[0002] The ultra-high pressure filtration device for leachate treatment is a device used to treat leachate (i.e. liquid containing solid particles). It is generally used in garbage disposal operations. This device uses ultra-high pressure to pass the leachate through the filter medium, thereby separating the solid particles and obtaining a relatively pure liquid product.

[0003] After searching, Chinese patent announcement number: CN219256549U discloses an ultra-high pressure filtering device for landfill leachate treatment equipment, including a base, the upper end surface of the base is fixedly connected to two support rods, and a movable plate is slidably connected between the two support rods. The utility model can clamp and fix the separation box so that it is not easy to deviate during separation.

[0004] Although the above device can fix the separation box, during use, since the device drives the extrusion plate downward through the motor transmission, and the two sets of clamping plates move to clamp the separation box, when the width of the separation box is too large, the extrusion plate may not move downward far enough after the clamping plate completes the clamping, resulting in failure to squeeze. Or when the width of the separation box is too small, the clamping plate has not yet contacted the side wall of the separation box after the extrusion plate moves downward for squeezing, thereby failing to achieve a good clamping and fixing effect. The device has poor adaptability to garbage separation boxes of different sizes. Therefore, an ultra-high pressure filtration device for leachate treatment is proposed to solve the above problems.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 The utility model provides an embodiment: an ultra-high pressure filtering device for leachate treatment, comprising a base 1, which can be placed on a bracket or a workbench to support the device as a whole and perform leachate treatment operations. The top outer wall of the base 1 is fixedly connected with a vertical plate 5, and the vertical plate 5 is provided with two groups. The top outer wall of the vertical plate 5 is fixedly connected with a motor 6, and the output shaft of the motor 6 is fixedly connected with a threaded rod 7. When the motor 6 is started, the output shaft of the motor 6 can drive the threaded rod 7 to rotate.

[0034] Reference Figure 1 The inner wall of the vertical plate 5 is fixedly connected with a guide rod 8, and the outer wall of the guide rod 8 is slidably connected with a movable plate 9, and the movable plate 9 is threadedly connected with the threaded rod 7. When the threaded rod 7 rotates, the guide rod 8 can guide the movable plate 9, so that the movable plate 9 can move vertically up and down along the inner wall of the vertical plate 5, and can drive the squeezing plate 404 to move up and down to squeeze the garbage inside the processing box 10. The outer wall of the movable plate 9 is provided with a mounting mechanism 4, and the squeezing plate 404 can be disassembled and installed through the mounting mechanism 4, and the squeezing plate 404 can be replaced to adapt to processing boxes 10 of different sizes.

[0035] Reference Figure 1 The top outer wall of the base 1 contacts with a processing box 10, and the inner wall of the processing box 10 is fixedly connected with a filter screen 11. The processing box 10 and the filter screen 11 are prior art. The garbage to be squeezed and filtered can be placed in the processing box 10. After squeezing, the liquid passes through the filter screen 11 and is discharged from the through hole at the bottom of the processing box 10. The inner wall of the base 1 is provided with a fixing mechanism 2. Through the fixing mechanism 2, the processing boxes 10 of different sizes can be clamped and fixed conveniently and quickly to avoid displacement during the squeezing and filtering process and affecting the squeezing effect.

[0036] Reference Figure 2-Figure 3 The fixing mechanism 2 includes a fixing plate 201, which is provided with two groups and symmetrically distributed on both sides of the base 1. The outer wall of the fixing plate 201 is hinged with a pull rod 205 through a connecting rod 204. One end of the connecting rod 204 is hinged to the outer wall of the fixing plate 201, and the other end of the connecting rod 204 is hinged to the outer wall of the pull rod 205. When the pull rod 205 is pulled or pushed, the fixing plate 201 can be driven to move to the middle or both sides by flipping the connecting rod 204.

[0037] Reference Figure 2-Figure 3 The pull rod 205 is slidably connected to the inner wall of the base 1, and a groove 206 is provided on the outer wall of the bottom end of the pull rod 205. There are multiple groups of grooves 206, so that the pull rod 205 can be fixed at multiple positions to move the fixing plate 201 to multiple positions for fixing, which is suitable for treatment boxes 10 of different widths. The outer wall of the base 1 is provided with a water outlet 203. When the base 1 is placed on a bracket or a workbench, the water outlet 203 is connected to an external treatment pipe, and the filtered leachate in the treatment box 10 can be discharged through the water outlet 203.

[0038] Reference Figure 2-Figure 3 A through slot 202 is provided on the outer wall of the base 1, and the fixed plate 201 is slidably connected to the inner wall of the through slot 202. When the moving rod 205 moves the fixed plate 201, the through slot 202 guides it, so that the fixed plate 201 can keep moving toward the middle or both sides at the same time. A limiting component is provided on the front outer wall of the base 1, and the position of the pull rod 205 can be fixed by the limiting component, and the limit of the pull rod 205 can be released quickly and conveniently.

[0039] Reference Figure 4 The limit assembly includes a fixed block 301, which is fixedly connected to the front outer wall of the base 1. The inner wall of the fixed block 301 is elastically connected to a stopper 303 through a spring A302. The arc surface of the stopper 303 remains facing the base 1, and a shift block is provided on the outer wall of the stopper 303. The shift block passes through the outer wall of one side of the fixed block 301. The shift block can be driven to move downward. One end of the spring A302 is fixedly connected to the outer wall of the stopper 303, and the other end of the spring A302 is fixedly connected to the inner wall of the fixed block 301. Under the influence of force, the spring A302 drives the block 303 to remain in an upward pop-up state due to the elastic force, and the straight surface of the block 303 contacts the inner wall of the groove 206, so that the pull rod 205 cannot move inward, and the clamping state of the fixed plate 201 is maintained. The outer wall of the block 303 is slidably connected with the inner wall of the fixed block 301, and the block 303 is engaged with the groove 206. When the pull rod 205 is pulled outward, the inner wall of the groove 206 squeezes the arc surface of the block 303, so that the block 303 moves downward along the inner wall of the fixed block 301, and the pull rod 205 can be pulled outward.

[0040] Reference Figure 5The mounting mechanism 4 includes a connecting block 401, which is fixedly connected to the outer wall of the bottom end of the movable plate 9. The extrusion plate 404 can be installed on the connecting block 401. The inner wall of the connecting block 401 is elastically connected with a card block 403 through a spring B402. The card block 403 includes two protrusions, which are symmetrically distributed at the top and bottom. One end of the spring B402 is fixedly connected to the outer wall of the card block 403, and the other end of the spring B402 is fixedly connected to the inner wall of the connecting block 401. When the extrusion plate 404 is installed on the connecting block 401, the spring B402 can drive the card block 403 to pop out due to its own elastic force, and a group of protrusions below are engaged with the card slot 405, thereby limiting the extrusion plate 404.

[0041] Reference Figure 5 The outer wall of the card block 403 is slidably connected to the inner wall of the connecting block 401, and the outer wall of the connecting block 401 is detachably installed with an extrusion plate 404. When the motor 6 is started, the threaded rod 7 rotates to drive the movable plate 9 and the extrusion plate 404 to move downward, so that the garbage inside the treatment box 10 can be squeezed and the leachate can be filtered. The outer wall of the extrusion plate 404 is provided with a card slot 405, and the card block 403 is engaged with the card slot 405. By pressing a group of protrusions on the top, the protrusions on the bottom can be driven to move and disengage from the card slot 405, and the extrusion plate 404 can be removed, and the appropriate extrusion plate 404 can be replaced according to the size of the treatment box 10.

[0042] Working principle: The operator can first place the garbage on the filter screen 11 in the treatment box 10, and then place the treatment box 10 on the base 1, so that the through hole at the bottom of the treatment box 10 corresponds to the position of the water outlet 203, and then adjust the position of the two sets of fixed plates 201 according to the size of the treatment box 10. At this time, the pull rod 205 can be directly pulled outward, and the inner wall of the groove 206 exerts a squeezing force on the arc surface of the stopper 303, so that the stopper 303 moves downward along the inner wall of the fixed block 301, and the pull rod 205 can be pulled out, and the two sets of fixed plates can be driven by the connecting rod 204. The fixed plate 201 moves, and the fixed plate 201 is guided by the through groove 202 and moves toward the middle at the same time. When the fixed plate 201 moves to fit the outer walls of the two sides of the processing box 10, the stopper 303 pops up upward due to the elastic force of the spring A302 and engages with the groove 206, which can limit the pull rod 205 in one direction and make it impossible for the pull rod 205 to move. The positions of the two groups of fixed plates 201 can be fixed, and the clamping and fixing effect of the processing box 10 is maintained, avoiding the problem that the processing box 10 is offset due to the force during the extrusion and filtration process, thereby affecting the extrusion and filtration effect.

[0043] When it is necessary to replace a processing box 10 of a different size, the push block on the outer wall of the stop block 303 can be pushed downward to drive the stop block 303 to move downward and out of contact with the groove 206, so that the limit of the pull rod 205 can be released, and the pull rod 205 can be pushed inward to drive the fixing plate 201 to move to both sides through the connecting rod 204 to adapt to a larger processing box 10. By setting multiple groups of grooves 206, the pull rod 205 can be fixed in multiple positions, thereby fixing the two groups of fixing plates 201 in multiple positions, and processing boxes 10 of different widths can be clamped, which has higher adaptability and is more convenient and quick to operate.

[0044] When squeezing the garbage inside the treatment box 10, the motor 6 can be started to rotate the threaded rod 7 to drive the movable plate 9 to move downward, and the garbage inside the treatment box 10 is squeezed through the squeezing plate 404. The squeezed leachate is filtered by the filter screen 11 and flows out through the through hole at the bottom of the treatment box 10 and the water outlet 203 to the external device for the next step of processing. When squeezing and filtering treatment boxes 10 of different sizes, the size of the adapted squeezing plate 404 needs to be replaced. At this time, a group of protrusions above the card block 403 can be pressed to drive the protrusions below to move along the connecting The inner wall of the connecting block 401 moves inward and disengages from the slot 405, so that the limit of the extrusion plate 404 can be released and the extrusion plate 404 can be removed for replacement. When installing the adapted extrusion plate 404, the upper protrusion can be pressed again to move the extrusion plate 404 upward along the bottom end of the connecting block 401. When the extrusion plate 404 moves to the position corresponding to the slot 405 and the position of the lower group of protrusions, the elastic force of the spring B402 drives the block 403 to pop outward, so that the lower group of protrusions are engaged with the slot 405, and the installation of the extrusion plate 404 is completed, which is more convenient.
