Embodiment Construction

[0016] The present invention will be further elaborated and illustrated below in conjunction with the accompanying drawings and specific embodiments.

[0017] As shown in the figure, a drum filter that facilitates the production of pharmaceutical intermediate catalysts includes a drum 1, a frame 2 and a motor. The middle of the drum 1 is provided with a pressure pipe 5 and a liquid outlet pipe 6. A feed pipe 7 is provided, the frame 2 is installed on the base 4, the surface of the drum 1 is provided with a filter cloth 1-1, and the filter cake 3 filtered out by the filter cloth 1-1 is placed on the drum The middle of one end of 1 is cut off by the lower scraper 9 and introduced into the feed bin 14. A slurry tank 8 is provided between the bottom end of the drum 1 and the frame 2, and a vertical shaft standing on the ground is provided outside the feed bin 14. Support 10, the top of the vertical support 10 is connected to the horizontal horizontal support 11, the horizontal sup...

Abstract

The invention relates to a drum filter capable of enabling medical intermediate catalysts to be produced conveniently. The drum filter comprises a rotary cylinder, a rack and a motor; a vertical bracket standing on the ground is further arranged on the outer side of a bin; the top end of the vertical bracket is connected with a horizontal transverse bracket; a feeding mechanism is arranged on thetransverse bracket, and the lower end of the feeding mechanism is fixedly connected with an upper scraper; the upper scraper is located above a lower scraper, is parallel to the lower scraper, and meanwhile tangentially makes contact with a filter cake; and the truncation end of the filter cake penetrates through the position between the upper scraper and the lower scraper. The drum filter has thecharacteristics of being easy to unload, low in abrasion degree of the scrapers, capable of effectively preventing the feedback phenomenon, high in cleanliness degree, and small in machine running resistance.

Description

technical field [0001] The invention belongs to the field of catalyst production equipment, and in particular relates to a drum filter for conveniently producing pharmaceutical intermediate catalysts. Background technique [0002] Drum filter is a kind of continuous filter, its structure is similar to that of drum vacuum filter, and its operating principle is also the same. It is a continuous filter with negative pressure as the driving force and the filter surface is on the surface of the cylindrical drum. The drum filter has good sealing performance, can obtain filter cake with low moisture content, and has high production efficiency. [0003] At present, the drum filter that adopts scraper discharge has disadvantages such as difficulty in unloading the filter cake with high viscosity, serious scraper wear, easy return to material, low cleanliness, and large machine rotation resistance. Contents of the invention [0004] In order to solve the above-mentioned technical ...
