Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to an explosion-proof filter press. Background Art

[0002] A filter press is a mechanical device that uses a special filter medium to apply a certain pressure to an object, causing the liquid to seep out to achieve solid-liquid separation. The main components of a filter press include a frame, a hydraulic system, a clamping plate, a thrust plate, a filter plate, and a filter cloth. During operation, when the liquid passes through the filter medium (usually composed of multiple layers of filter cloth or filter plates), the filter press applies a certain pressure, which can be generated by a hydraulic system or a mechanical device. The purpose of applying pressure is to increase the penetration rate and filtering effect of the liquid in the filter medium. Under pressure, the liquid will penetrate from the top to the bottom of the filter medium. In this process, suspended matter or solid particles are intercepted, and the liquid flows out through the filter medium.

[0003] Explosion-proof filter press is a specially designed filter press, which is mainly used for solid-liquid separation in industrial fields (chemical, pharmaceutical, mining, etc.) where explosive environments may exist. It is achieved by using explosion-proof electrical components, explosion-proof housings and special explosion-proof measures. Its main feature is that it can operate safely in dangerous environments and avoid explosion accidents caused by improper operation or equipment failure.

[0004] After the existing explosion-proof filter press finishes squeezing the material, some of the material will adhere to the extrusion plate. If the material adhered to the extrusion plate is not cleaned, the extrusion effect of the material will be reduced during the next filtration, and the material will not be squeezed thoroughly enough. If the filter press barrel is opened to clean the extrusion plate after each extrusion, the frequency of manual cleaning will be high, which increases the workload of the workers.

[0021] In order to facilitate the discharge of solid waste in the filter press chamber 2, the bottom surface of the inner wall of the barrel 1 is symmetrically arranged with a slag discharge opening 16, and the two slag discharge openings 16 are respectively arranged on the left and right sides of the liquid discharge opening. The left and right sides of the bottom surface of the inner wall of the liquid storage tank 14 are fixedly connected with a fourth cylinder 17, and the telescopic end of each fourth cylinder 17 is fixedly connected with a sealing block 18. The two sealing blocks 18 are respectively inserted into the slag discharge openings 16 on the left and right sides. The fourth cylinder 17 is electrically connected to the controller 10, and the left and right sides of the liquid storage tank 14 are opened with cleaning openings 19.

[0022] In order to prevent the liquid entering the liquid storage tank 14 from flowing to the fourth cylinder 17 on both sides, a partition 20 is fixedly connected to the front and rear sides of the inner wall of the liquid storage tank 14. The top surface and the bottom surface of the partition 20 are respectively fixedly connected to the bottom surface of the inner wall of the liquid storage tank 14 and the bottom surface of the barrel 1.

[0023] In order to enter the filter press chamber 2 to inspect or clean the mechanism in the filter press chamber 2, an inspection opening is opened in the middle of the front side of the barrel 1, and a sealing door 21 is hingedly connected to the middle of the front side of the barrel 1.

[0024] In order to allow the feed pipe 11 to pass through the movable cleaning scraper 9 and thus allow the material in the feed pipe 11 to fall into the filter press chamber 2 , a through hole 22 is opened in the middle of the cleaning scraper 9 , and the through hole 22 is adapted to the feed pipe 11 .

[0025] In order to facilitate knowing the pressure inside the barrel 1 and avoid the barrel 1 exploding due to not knowing that the internal pressure of the barrel 1 is too high, a pressure gauge 23 is fixedly connected to the left side of the top of the barrel 1, and the detection head on the pressure gauge 23 penetrates into the filter press chamber 2.

[0026] In order to prevent the material from flowing to the separated sides of the first extrusion plate 6 and the second extrusion plate 7, which makes it difficult to discharge the material, the front and rear sides of the first extrusion plate 6 and the second extrusion plate 7 are respectively fitted with the front and rear sides of the filter press chamber 2, and the top and bottom surfaces of the first extrusion plate 6 and the second extrusion plate 7 are respectively fitted with the top and bottom surfaces of the filter press chamber 2, and the side surfaces of the first extrusion plate 6 and the second extrusion plate 7 are fixedly sleeved with sealing rings.

[0027] Working principle: When the utility model is used, the third cylinder 8 is first started by the controller 10, and the third cylinder 8 pushes the cleaning scraper 9 to descend, so that the left and right sides of the cleaning scraper 9 scrape the left side of the first extrusion plate 6 and the right side of the second extrusion plate 7 respectively, and the materials attached to the first extrusion plate 6 and the second extrusion plate 7 are scraped off, thereby cleaning the first extrusion plate 6 and the second extrusion plate 7 to ensure the effect of the next material extrusion and the thorough extrusion of the materials, reducing the frequency of manual cleaning of the first extrusion plate 6 and the second extrusion plate 7, thereby reducing the workload of the workers. After the first extrusion plate 6 and the second extrusion plate 7 are cleaned, the third cylinder 8 drives the cleaning scraper 9 to rise and enter the storage chamber 3, and the lower end of the feed pipe 11 passes through the through hole 22, and then the raw material is poured into the feed hopper 12. The raw material falls into the filter press chamber 2 through the feed pipe 11 and is located between the first extrusion plate 6 and the second The first and second cylinders 4 and 5 are respectively pushed by the first and second cylinders 5 to move the first and second extrusion plates 6 and 7 toward the middle of the filter press chamber 2 to extrude the material. After the material is extruded, it is filtered through the filter screen 13, and the liquid enters the liquid storage tank 14 and is discharged through the drain pipe 15. After the liquid in the filter press chamber 2 is discharged, the fourth cylinder 17 is started by the controller 10, and the fourth cylinder 17 drives the sealing block 18 to descend, so that the sealing block 18 is moved out of the slag discharge opening 16. Then, by using the first cylinder 4 and the second cylinder 5 to drive the first extrusion plate 6 and the second extrusion plate 7 to move, the solid waste in the filter press chamber 2 can be discharged through the slag discharge opening 16, so that the solid waste falls into the liquid storage tank 14, and the solid waste is taken out of the liquid storage tank 14 through the cleaning opening 19.

[0028] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
