The air inlet (2) is formed in the upper portion of the tank (1), and an air distributing plate (3) is arranged between the air inlet (2) and the tank (1); the feed hopper (7) is arranged on the top of the tank (1), and a feed guide pipe (5) is arranged below the feed hopper (7); a spiral distributing machine (6) is arranged between the feed hopper (7) and the feed guide pipe (5); the upper end of the screen cloth (4) is fixed to the inner wall of the tank (1) and is hinged to the rear side of the feed guide pipe (5), and the lower end of the screen cloth (4) is hinged to the upper end of an arc-shaped partition plate (12); the lower end of the arc-shaped partition plate (12) extends between a pair of rolls (13) which are fixed to the inner wall of the tank (1). The novel combined screening machine has the obvious advantages that the novel combined screening machine is simple in structure, convenient to operate and high in mud (or stone) powder removing efficiency, is economical and practical and can run stably and reliably, and the product grading quality can be guaranteed.

The invention discloses a manufacturing method of a silk screen plate capable of reducing gate breaking under electroluminescence imaging. The mesh of the silk screen plate is 290. The silk diameter of the screen cloth on the silk screen plate is 20 micrometers. The membrane thickness of the silk screen plate is 15 micrometers. The tension of the silk screen plate is 26N. The total thickness of the silk screen plate is 45 micrometers. Terpineol is added to the silver paste of the printing silk screen plate, the volume mass ratio of the terpineol is 0.5%, the distance between the screen plate and a printing tabletop is 800-1000 micrometers, and the printing speed is 180-200mm / s. The specification of original silk screen plates is changed, the mesh, silk diameter and membrane thickness of the silk screen plate are lowered, the screen quantity of paste is increased, gate breaking during printing is reduced, the paste is thinned by adding the terpineol into the silver paste, the silver paste can be evenly sprayed by the silk screen plate distance and the printing speed, battery gate breaking quantity is reduced, and battery piece production yield is increased. The silk screen plate is simple in structure, convenient to operation and refined in process, battery piece production efficiency is increased, and gate breaking is reduced.

The invention relates to a mixed product comprising beta-glucan, which is prepared by the following raw materials in ratio by weight: 7.5-80% of beta-glucan, 6-20% of cocoa butter, 0-30% of supermicro carrot powder, 0-30% of supermicro highland barley, and 0-40% of erythritol. Meanwhile, the invention further discloses a preparation method of the product. In the mixed product, beta-glucan can be quickly dissolved in daily drinking water. The mixed product has a certain healthcare effect, is convenient to have and good in taste, and can meet the recommended dose of beta-glucan to reach the health keeping effect.

The invention provides a work bench of a laser cutting ceramic circuit substrate. The work bench is a combined unit of an upper structure and a lower structure and is composed of a fixed base and a flexible connecting mobile station; the fixed base is a hollow columnar cylinder body; the bottom end of the fixed base is sealed; the cylinder body is radially provided with a vacuum port air nozzle (7) which is connected with a vacuum apparatus; the flexible connecting mobile station is located above the fixed base (6) and is an annular plate with a radial outer edge, and is axially provided with a locating annular base (2) with a conical lug boss and a locking ring (1) which is coaxially fitted on a conical surface of the conical lug boss; circular ring steps, which are gradually amplified along an inner wall conical surface, are arranged on a conical hole surface of an inner cavity of the locating ring base; a wire mesh for supporting and locating the drilling ceramic substrate to be cut is tightened on an annular end plane of a central hole of the locating ring base (2); clamping and tightening are accomplished through a conical degree fitting surface between the locking ring and the locking ring base. According to the work bench, the problems that the laser cutting drilling ceramic circuit board is always hard to clean and needs to re-condense Al2O3 ceramic nodule are solved.

The invention relates to a membrane producing method capable of improving surface smoothness of a lined microfiltration membrane. The membrane producing method comprises the following specific steps: putting resin, a solvent and an additive into a stirring kettle according to a certain proportion, stirring and dissolving to form a membrane casting solution; defoaming the formed membrane casting solution, and enabling the membrane casting solution to pass through a spinning kettle and a filter and enter a spinneret plate; atomizing a supporting body by using an atomizing device, enabling the supporting body to enter the spinneret plate, and combining the supporting body and the membrane casting solution at an outlet of the spinneret plate so as to uniformly coat the surface of the supporting body with the membrane casting solution to form membrane filaments; primarily shaping the membrane filaments after passing through a gel bath, then passing through other gel tanks to further separate out DMAC in the membrane casting solution into a water solution, diffusing water into membrane pores, and finally winding and post-processing to form the finished membrane filaments, and storing the finished membrane filaments in a filament receiving machine. By the preparation process, through atomization of the supporting body, the cost of the supporting body can be reduced while the surface smoothness of the membrane is ensured; the membrane producing method is simple and controllable in preparation process; in the process of combining the membrane casting solution and the supporting body, an adjustable variant is increased, so that the breadth of a product is increased.

The invention discloses a horizontal stirring and drying device capable of preventing caking of materials. The horizontal stirring and drying device capable of preventing caking of materials comprisesa base, an outer shell and an inner shell, wherein the outer shell is fixedly mounted on the base; the inner shell is accommodated in the outer shell; the length of the inner shell is consistent to that of the outer shell; one side of the outer shell and one side of the inner shell are fixedly connected in a sealed manner through a first sealing plate; the other side of the outer shell and the other side of the inner shell are fixedly connected in a sealed manner through a second sealing plate; a stirring arm which is inserted into the inner shell is rotatably arranged on the second sealing plate in a sealed manner; and a swing mechanism which is matched with the stirring arm is arranged at the lower end of the inside of the inner shell. The swing mechanism is cooperatively designed at the bottom of the drying device, materials are pulverized, and the problem that materials in a horizontal dryer are caked is solved effectively.
