A gasket insertion method for inserting a gasket into an outer cylinder includes providing an outer cylinder having a base end opening section; providing a gasket having a recessed section that is open at a base end of the gasket and that includes a flat bottom surface; pushing the gasket into a sleeve configured to be inserted into the outer cylinder, by relatively moving an inserter in a tip end direction with respect to the sleeve while a flat tip end surface of a tip end section of the inserter abuts the bottom surface of the recessed section; inserting the sleeve into the outer cylinder through the base end opening section; and arranging the gasket inside the outer cylinder by relatively moving the sleeve in a base end direction with respect to the outer cylinder while maintaining relative axial positions of the outer cylinder, the gasket, and the inserter.

The invention relates to an electrolytic device and provides a device for preparing tetravalent uranium by electrolytic reduction to solve the problems of low tetravalent uranium yield of an existing diaphragm-free electrolysis device and complicated equipment, high cost and the like of a diaphragm electrolysis device. The device comprises an electrolytic tank body with an insulated inner wall, an anodic platinized and titanized rod and a cathodic titanium net, wherein the cathodic titanium net is barrel-shaped, the anodic platinized and titanized rod is arranged on the axial line of the barrel-shaped cathodic titanium net, and the surface area ratio of the cathodic titanium net to the anodic platinized and titanized rod is (10 to 1) to (20 to 1). The device for preparing tetravalent uranium by electrolytic reduction is simple in structure, high in tetravalent uranium yield and more convenient to operate and repair, overcomes the defect of low tetravalent uranium yield of the existing diaphragm-free electrolysis device and solves the problems of complicated equipment, high cost and the like of the diaphragm electrolysis device; the tetravalent uranium yield is more than 90% during a static electrolytic process.

The invention discloses a loofah sponge zeolite molecular sieve for water muddy matter adsorption separation and a preparation method of the loofah sponge zeolite molecular sieve. The loofah sponge zeolite molecular sieve comprises the following raw materials in parts by weight: 120-140 parts of loofah sponge fiber, 2-5 parts of zinc chloride, 3-6 parts of potassium hydroxide, 6-8 parts of sulfuric acid, 20-40 parts of silica gel, 30-50 parts of water glass, 15-25 parts of sodium silicate, 30-40 parts of aluminum orthophosphite, 20-40 parts of aluminum sulfate, 8-12 parts of hydrochloric acid, 20-30 parts of chitosan and the balance of water. According to the invention, the loofah sponge fiber can create a carrier environment for zeolite gel to enable a bundle structure and a pore structure of the loofah sponge fiber to be filled with the zeolite gel, so that the loofah sponge zeolite molecular sieve is more stable and does not deactivate easily, meanwhile, the surface area ratio is increased and adsorbability is improved.

The invention discloses a control device for heating temperature of a cylindrical workpiece, which comprises a control device body, the control device body is provided with a bracket supporting a plurality of workpieces to be heated, and the plurality of workpieces to be heated are evenly and symmetrically distributed among In the heating furnace, temperature-measuring thermocouples are installed at the positions where the bracket is in contact with multiple workpieces to be heated, a temperature-measuring camera is installed on the inner furnace surface of the heating furnace, and left-side The burner and the right burner, the heating furnace is electrically connected with a computer that collects and processes the heating temperature signals of multiple workpieces to be heated and controls the heating. The present invention abandons the traditional control method that takes the temperature in the furnace as the object, The temperature adjustment and control is directly targeted at the workpiece to be heated, which greatly improves the control accuracy of heating and the effective heating rate and heating quality of the workpiece to be heated.

The present invention provides an intake circulatory system for a zinc air fuel cell, including a housing, a zinc air cell, an air supply system and an air collecting system. The housing is partitioned on the inside of the intake circulatory system for a zinc air fuel cell to form a first space and a second space. The zinc air cell is assembled on the inside of the housing, and includes a discharging region that is located in the first space and a charging region that is located in the second space. Moreover, the air supply system includes an air supply device and an air intake device that is in connection with the air supply device and the first space. In addition, the air collecting system includes an air collecting device that is in connection with the air intake device, and at least one air output pipe exists in between the air collecting device and the second space. Further, in accordance with the present invention, the air supply device transmits external air to the first space via the air intake device. The discharging region of the zinc air cell has a chemical reaction with oxygen from the external air to generate electricity. The charging region produces oxygen by generating electricity to perform a reduction reaction. The air collecting device absorbs oxygen and also transmits the oxygen to the air intake device. The external air and the oxygen are mixed and subsequently enter the first space. As such, the power supply efficiency of the discharging region is increased in accordance with the present invention.
