Description

Technical Field

[0002] A filter press is a type of filtration equipment used for solid-liquid separation, widely used in various fields such as chemical, fuel, pharmaceutical, food, papermaking, coal washing, and sewage treatment. The working principle of a filter press is to use the pores of the filter medium to separate solid particles from a suspension through applied pressure. A filter press typically consists of a compression plate, thrust plate, filter plates, hydraulic cylinder, main beam, transmission, and pull-out mechanism. During operation, the hydraulic cylinder piston pushes the head plate, pressing the filter plates against adjacent filter plates to form a filter chamber. A feed pump delivers slurry into the filter chamber, where water permeates the filter cloth and is discharged through the drain port. The solid slurry forms a filter cake in the filter chamber. Once the chamber is filled with slurry, a high-pressure pump continues to pressurize the slurry, separating the solids and liquids within the chamber.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1 、 Figure 2 and Figure 3The present invention provides a technical solution: there are many methods for separating and purifying the reaction mixture, including natural sedimentation, accelerated sedimentation, filtration separation, distillation separation, etc. The selection of the specific method depends on the properties of the mixture and the substances to be separated. When a filter press separator is used to separate the reaction mixture, the filter press separator has the advantages of high efficiency and energy saving, and can simultaneously complete the separation process of solids and liquids, thereby improving production efficiency. The reaction mixture filter press separation device includes a filter press frame 100, one end of the filter press frame 100 is fixedly mounted with a feed seat plate 101, the other end of the filter press frame 100 is fixedly mounted with a press drive cylinder 105, one end of the press drive cylinder 105 is located on the inner side of the filter press frame 100 and a press plate 104 is installed, and one end of the feed seat plate 101 is fixedly mounted with a press drive cylinder 105. A feed pipe 102 is installed at the end, and the feed pipe 102 can pass the reaction mixture into the filter press plate 103. A gear assembly is installed on one side of the filter press frame 100, and the gear assembly includes a telescopic block 204. A reciprocating motor 200 is fixedly installed on the front surface of the other end of the filter press frame 100. One end of the reciprocating motor 200 is located in the filter press frame 100 and a threaded drive rod 203 is installed. A reciprocating groove 201 is provided inside the filter press frame 100, and a movable threaded guide block 202 is installed in the reciprocating groove 201, and a telescopic block 204 is installed at the bottom of the threaded guide block 202. When using the filter press separator in this application, the reaction mixture is passed into the filter press equipment through the feed pipe 102. After the reaction mixture is passed into the equipment, the equipment works and passes The overpressure driving cylinder 105 works to push the pressure plate 104 to move and squeeze the filter press plate 103, thereby separating the solid and liquid in the reaction mixture. During the separation operation and installation of the filter press plate 103, multiple filter press plates 103 need to be assembled individually. If they shake unstable during assembly and placement, the stability of the installation will be affected, and the work efficiency will be affected. After the pressure plate 104 is placed, the reciprocating motor 200 on the filter press frame 100 works to drive the threaded drive rod 203 inside the reciprocating groove 201 to rotate. The rotation of the threaded drive rod 203 drives the threaded guide block 202 to move in the reciprocating groove 201 through the thread. When the threaded guide block 202 moves, the telescopic block seat 204 moves synchronously. When the filter press plate 103 is placed on the filter plate support arm 106 After the filter press frame 100 is mounted, the telescopic stopper 204 moves to the edge of the filter press plate 103 and contacts and squeezes the filter press plate 103 through the filter plate stopper 205, thereby ensuring the stability of the filter press plate 103 after installation and preventing the filter press plate 103 from shaking during assembly.

When the filter plate stopper 205 contacts the pressure plate 104, it can be pushed back better. A telescopic limit rod 206 is fixedly installed at one end of the stopper 205, and a telescopic spring 207 is sleeved on the inner side of the telescopic groove 208 on the telescopic limit rod 206. The filter plate stopper 205 is limited and installed on the telescopic stopper seat 204 by the telescopic limit rod 206, and the filter plate stopper 205 is telescopically moved in the telescopic groove 208 by the telescopic limit rod 206. When the filter press plate 103 contacts the filter plate stopper 205, the filter plate stopper 205 will not move. When the pressing plate 104 contacts the inclined surface of the filter plate stopper 205, the filter plate stopper 205 can be squeezed back into the telescopic stopper seat 204.
