Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically to a jet-discharge filter press. Background Technology

[0002] A blow-out filter press is a device used for solid-liquid separation. It uses pressure to force a suspension through a filter cloth, allowing the liquid to pass through the filter cloth and be discharged. Solid particles are trapped on the surface of the filter cloth, forming a filter cake. After filtration, high-pressure gas is blown from the opposite direction of the filter plate to peel the filter cake off the filter cloth, thus achieving unloading. Compared with the manual unloading or mechanical scraping of traditional filter presses, it is more efficient and thorough.

[0003] In the prior art, a filter press angle blowing process device with patent publication number CN215462274U includes a thrust plate and a pressing plate at both ends of the main beam. A filter plate is pressed between the thrust plate and the pressing plate. The angle blowing holes on both sides of the upper end of the filter plate are the upper air inlet and the angle blowing holes on both sides of the lower end of the filter plate are the lower air outlet. The corresponding angle blowing holes of each pressed filter plate are connected to form an internal channel of the filter plate. The thrust plate is provided with an upper air inlet and a lower air outlet corresponding to the air inlet and lower air outlet of the filter plate.

[0004] When the device uses an air pump for blow-off unloading, the airflow usually carries external impurities, dust, and various other contaminants through the duct. Over time, these substances adhere to and accumulate on the inner wall of the duct, eventually causing severe blockage and hindering the normal flow of air. This significantly reduces the efficiency of blow-off unloading. Furthermore, when disassembling and maintaining the duct, the lack of a mechanism to block moisture from the filter plates makes it easy for moisture to flow back through the duct, resulting in pollution of the workshop floor, impacting the working environment, and increasing maintenance costs.

[0012] Furthermore, the fixing tube includes a connecting column fixedly connected to the inner surface of the turbine column, and a scraper fixedly sleeved on the outer end face of the connecting column and used in conjunction with the filter screen.

[0013] Furthermore, a rotating bearing sleeve is installed at the connection between the connecting column and the fixed pipe, and the outer surface of the scraper is in frictional contact with the outer surface of the filter screen.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] Example: A blow-out filter press, as shown in the attached figure. Figure 1 -Appendix Figure 5 ,include,

[0032] The filter press body 100 includes a frame 110, a cylinder 120 adapted to be installed on the outside of the frame 110, a plurality of filter plates 130 disposed on the inside of the frame 110, a filter cake frame 140 disposed directly below the filter plates 130, an air duct 150 connected to the four corners of the filter plates 130, and an air pump 160 disposed on the outside of the frame 110 and used in conjunction with the air duct 150.

[0033] It should be noted that the frame 110 is used to support the equipment, fix components such as the cylinder 120 and the filter plate 130, and ensure structural stability. The cylinder 120 is used to provide pressing power to the filter plate 130, so that a sealed filtration chamber is formed between the filter plates 130. The filter plate 130 is used to support the filter cloth and form a solid-liquid separation space. The filter cake frame 140 is used to receive the filter cake that is peeled off during unloading. The air duct 150 is used to transport the high-pressure gas provided by the air pump 160 to the four corners of the filter plate 130 for spray unloading. The filter press body 100 is existing technology, and this solution will not describe it in detail. Moreover, those skilled in the art can clearly understand its working principle.

[0034] The sealing mechanism 200 includes an anti-blocking component 210 for preventing the duct 150 from being blocked, a connecting component 220 for connecting the anti-blocking component 210 and the duct 150, and a disconnecting component 230 that can automatically block the duct 150 when the anti-blocking component 210 and the duct 150 are disconnected.

[0035] And, a mobile trolley 300 that works in conjunction with the control air pump 160 to move;

[0036] The anti-blocking component 210 is located at the air outlet of the air duct 150, the connecting component 220 is located at the adjacent end of the anti-blocking component 210 and the air duct 150, and the cut-off component 230 is provided in two sets, which are located in the connecting components 220 on both sides respectively.

[0037] The anti-clogging component 210 includes a fixed pipe 211 fixedly sleeved on the air outlet of the air duct 150, a filter screen 212 threadedly connected to the inner wall of the fixed pipe 211 and used to prevent dust from entering the air duct 150, and a turbine column 213 located at the center of the inner cavity of the fixed pipe 211.

[0038] Specifically, the fixed tube 211 includes a connecting column 214 fixedly connected to the inner surface of the turbine column 213, and a scraper 215 fixedly sleeved on the outer end face of the connecting column 214 and used in conjunction with the filter screen 212.

[0039] It should be noted that the fixing pipe 211 is used to support the filter screen 212 and the turbine column 213, and forms an airflow channel with the air outlet of the air duct 150. The filter screen 212 is used to intercept dust and impurities in the airflow, preventing dust and impurities from entering the air duct 150 and causing it to become blocked. The threaded connection makes it easy to disassemble and clean the filter screen 212 regularly. The turbine column 213 can rotate using the airflow power provided by the air pump 160, and drives the scraper 215 to rotate synchronously through the connecting column 214, so that the scraper 215 sweeps the impurities and dust attached to the surface of the filter screen 212 to the surrounding area, thereby preventing the filter screen 212 from becoming blocked when the air pump 160 is running.

[0040] Furthermore, a rotating bearing sleeve is installed at the connection between the connecting column 214 and the fixed tube 211, and the outer surface of the scraper 215 is in frictional contact with the outer surface of the filter screen 212.

[0041] Preferably, the connecting assembly 220 includes a plug tube 221 threaded to the inner wall of the fixed tube 211, a connecting sleeve 222 fixedly sleeved on the outer surface of the air duct 150 and used in conjunction with the fixed tube 211, a limiting groove 223 formed on the outer surface of the plug tube 221, and a plurality of balls 224 movably connected to the inner surface of the connecting sleeve 222 and used to limit the plug tube 221 in conjunction with the limiting groove 223.

[0042] It should be noted that the connecting assembly 220 also includes a sliding sleeve 225 that is slidably sleeved on the outer surface of the connecting cylinder 222 and is used to apply pressure to the ball 224, and a first spring 226 that is sleeved on the outside of the connecting cylinder 222 and is used to drive the sliding sleeve 225 to return to its original position.

[0043] It should be noted that when the insertion tube 221 is inserted into the connecting tube 222, the inner walls of the two are in contact to form an airflow channel. At the same time, the ball 224 slides on the outer surface of the insertion tube 221. When the insertion tube 221 is fully inserted into the connecting tube 222, it automatically falls into the limiting groove 223 and engages with it. The sliding sleeve 225 is used to push and squeeze the ball 224 inward to embed it into the limiting groove 223. When the sliding sleeve 225 is pulled outward, it can not only release the limiting of the ball 224, but also squeeze the first spring 226. The reaction force of the first spring 226 can reset the sliding sleeve 225 after it is released.

[0044] Furthermore, the first spring 226 is fixedly installed on the outer surface of the connecting cylinder 222, and its other end is fixedly connected to the sliding sleeve 225.

[0045] Specifically, the connecting assembly 230 includes a perforated plate 231 fixedly connected to the inner walls of the insertion tube 221 and the connecting cylinder 222, a telescopic rod 232 fixedly installed on the outer end face of the perforated plate 231, a plug 233 fixedly connected to the telescopic segment of the telescopic rod 232 and used to seal the insertion tube 221 and the connecting cylinder 222, a force-bearing end 234 integrally formed on the other end of the plug 233, and a second spring 235 sleeved on the outside of the telescopic rod 232.

[0046] It should be explained that the perforated plate 231 is used to ensure that airflow can pass through the connector 221 and the connecting cylinder 222, the telescopic rod 232 is used to support the plug 233 and provide it with telescopic guidance so that it can perform axial telescopic movement, the plug 233 is used to seal the interface between the connector 221 and the connecting cylinder 222 to prevent the filtrate from flowing back through the air duct 150. When the connector 221 and the connecting cylinder 222 are connected, the two force-bearing ends 234 squeeze each other, pushing the plug 233 to compress the second spring 235 at the same time, opening the channel. When the connector 221 and the connecting cylinder 222 are disconnected, the reaction force of the second spring 235 drives the plug 233 to reset, sealing the interface between the connector 221 and the connecting cylinder 222. The bottom of the moving trolley 300 is equipped with rollers, which can be manually pushed to drive the air pump 160 to connect to the air duct 150 interface.

[0047] Preferably, the two ends of the second spring 235 abut against the hollow plate 231 and the plug 233 respectively;

[0048] When the two force-bearing ends 234 press against each other, they can simultaneously drive the two plugs 233 to release the blockage of the insertion pipe 221 and the connecting cylinder 222, and connect the air duct 150, the fixed pipe 211, the insertion pipe 221, the connecting cylinder 222 and the air pump 160.

[0049] When using,

[0050] The trolley 300 drives the air pump 160 to the duct 150 interface, pulls the sliding sleeve 225 to release the limit on the ball 224, and then inserts the insertion tube 221 into the connecting tube 222. During the insertion process, the ball 224 slides along the outer surface of the insertion tube 221. After the insertion tube 221 is fully inserted into the connecting tube 222, the ball 224 automatically falls into the limiting groove 223 and engages with it.

[0051] At this time, the sliding sleeve 225 is released, and the sliding sleeve 225 is driven to return to its original position by the reaction force of the first spring 226, so that it squeezes the ball 224 and further embeds it into the limiting groove 223, ensuring the connection between the insertion tube 221 and the connecting tube 222.

[0052] When the insertion pipe 221 is connected to the connecting cylinder 222: the two force-bearing ends 234 press against each other, pushing the plug 233 to compress the second spring 235, releasing the blockage on the insertion pipe 221 and the connecting cylinder 222, so that the air duct 150, the fixed pipe 211, the insertion pipe 221, the connecting cylinder 222 and the air pump 160 are connected.

[0053] Next, the air pump 160 is started. The high-pressure gas generated by the air pump 160 is delivered to the four corners of the filter plate 130 through the air duct 150 for spraying and unloading. When the airflow passes through the fixed pipe 211, it impacts the turbine column 213 to make it rotate. The turbine column 213 drives the scraper 215 to rotate synchronously through the connecting column 214. Then, the scraper 215 comes into contact with the outer surface of the filter screen 212 through friction, sweeping the impurities and dust attached to the surface of the filter screen 212 to the surrounding area to prevent the filter screen 212 from clogging.

[0054] After unloading, when disassembling and maintaining the fixing pipe 211: pull the outer sliding sleeve 225 to release the limit on the ball 224. At the same time, the first spring 226 stretches and stores energy, pulling the insertion pipe 221 out of the connecting cylinder 222. The insertion pipe 221 is disconnected from the connecting cylinder 222, and the force-bearing end 234 is no longer squeezed. The elastic potential energy is released through the second spring 235, which drives the plug 233 to reset, sealing the interface between the insertion pipe 221 and the connecting cylinder 222, and preventing the water in the filter plate from flowing back through the air duct 150.

[0055] Subsequently, unscrew the connector 221 and the filter screen 212 in sequence, move the filter screen 212 to the designated area for cleaning, and after cleaning, screw the filter screen 212 and the connector 221 back into the connecting cylinder 222 in sequence, ensuring that the surfaces of the filter screen 212 and the scraper 215 are in contact.

[0056] In summary, by setting up the sealing mechanism 200, not only can the air duct 150 be prevented from being blocked by impurities in the airflow during the spray unloading process, ensuring smooth airflow, but also the path of water in the filter press 130 flowing back through the air duct 150 can be automatically blocked after the spray unloading is completed, thus preventing workshop pollution. This achieves the effect of ensuring unloading efficiency while avoiding increased maintenance costs.

[0057] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
