Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, specifically to a vertical sludge pressing device. Background Technology

[0002] With the rapid development of the national wastewater treatment industry, industry policies have gradually shifted from "emphasizing water treatment over sludge treatment" to "emphasizing both water and sludge treatment." Sludge treatment technologies have experienced rapid development during this policy transformation. Among the most important sludge reduction technologies, mechanical pressing dewatering offers advantages such as low investment, low operating costs, and low energy consumption.

[0003] Traditional mechanical dewatering technology for sludge mainly uses horizontal plate and frame filter presses. However, the adoption of horizontal plate and frame filter presses is limited due to their low level of automation, large footprint, complex structure, and frequent manual operation.

[0004] Vertical sludge pressing equipment typically uses a fixed filter press chamber with a lifting mechanism at the bottom. This type of equipment usually only has one filter press chamber, and during the pressing process, the press is in standby mode during both the feeding and discharging stages, resulting in high energy consumption. Summary of the Invention

[0005] This invention provides a vertical sludge pressing device, which is equipped with two movable filter chambers so that the feeding and discharging and pressing processes are carried out in different places. This allows a single press to process sludge from different filter chambers at different times, thereby improving sludge treatment capacity and reducing the energy consumption of the press during standby.

[0006] This invention is achieved through the following technical solution: a vertical sludge pressing device, comprising a frame, a press, a slide rail, a first filter chamber, a second filter chamber, a first sliding thrust cylinder, and a second sliding thrust cylinder. The first and second filter chambers are located on opposite sides of the press, and their tops are horizontally slidably fitted with the slide rail. The slide rail, the first sliding thrust cylinder, and the second sliding thrust cylinder are all mounted on the frame. The output shafts of the first and second sliding thrust cylinders are horizontally connected to the first and second filter chambers, respectively. The first and second sliding thrust cylinders can push the first and second filter chambers into the press, respectively.

[0007] Furthermore, both the first and second filter press chambers are provided with supports below them, and the first and second filter press chambers can be located on the two supports respectively.

[0008] Furthermore, the frame is connected to two sets of lifting cylinders, which are located on both sides of the slide rail, and the output shaft of the lifting cylinder is connected to the slide rail.

[0009] Furthermore, a lifting cylinder is connected to the support, and a lifting base plate is vertically slidably fitted inside both the first and second filter chambers. A lifting platform is connected to the output shaft of the lifting cylinder, and the lifting platform is detachably connected to the lifting base plate. A limiting base plate is connected to the bottom of both the first and second filter chambers, and the limiting base plate can limit the lowest position of the lifting base plate.

[0010] Furthermore, the lifting base plate includes an upper plate and a lower plate. The upper plate is located at the top of the lower plate and is connected to the lower plate. The lower plate has a plurality of countersunk holes evenly distributed on it. The lifting platform has a plurality of pneumatic positioning hooks evenly distributed on it. The plurality of countersunk holes on the lower plate can be sequentially engaged with the plurality of pneumatic positioning hooks on the lifting platform.

[0011] Furthermore, the inner walls of the first and second filter press chambers have a powder coating layer or are connected with plastic lining plates, wherein the powder coating layer and the plastic lining plates are made of polytetrafluoroethylene or ultra-high molecular weight polyethylene.

[0012] Furthermore, a side seam sealing gasket is connected to the lifting base plate, and the edge of the side seam sealing gasket is bent upward and attached to the inner wall of the filter press chamber.

[0013] Furthermore, the support is provided with a docking base, and the bottoms of the first and second filter press chambers are detachably connected to the docking base.

[0014] Furthermore, rollers are connected to the top of both the first and second filter press chambers. The rollers can slide along the slide rail, which is a V-shaped slide rail, and the shape of the rollers is adapted to the shape of the slide rail.

[0015] Furthermore, both the first and second filter press chambers are connected to lugs, and the first and second sliding thrust cylinders are respectively connected to the lugs on the first and second filter press chambers.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects: This invention separates the material feeding / discharging and pressing processes by setting up two filter chambers at two horizontal positions, allowing the feeding / discharging and pressing processes to occur in different locations. Thus, while the first sliding thrust cylinder pushes the first filter chamber to the pressing position for pressing, the other filter chamber can feed or discharge material. After the first filter chamber at the pressing position completes its pressing, the first sliding thrust cylinder pulls it back to its initial position for unloading, and the second sliding thrust cylinder then pushes the second filter chamber to the pressing position for pressing. This allows a single press to process sludge from different filter chambers at different times.

[0017] In this two-chamber filter press system, one chamber is performing the pressing process while the other is handling the feeding and discharging of materials. This alternating operation of the two chambers effectively improves the overall sludge processing capacity of the equipment and reduces the standby energy consumption during feeding and discharging. The alternating operation of the two chambers also enhances the overall efficiency of the sludge pressing process. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0021] Example 1 Figures 1-3 As shown, this embodiment 1 provides a vertical sludge pressing device, including a frame 6, a press 4, a slide rail 5, a filter chamber (in this embodiment, the filter chamber includes a first filter chamber 3 and a second filter chamber 301), a first sliding thrust cylinder 1, and a second sliding thrust cylinder 101.

[0022] The press 4 is located at the center of the frame 6. The first filter chamber 3 and the second filter chamber 301 are located on both sides of the press 4, and the tops of the first filter chamber 3 and the second filter chamber 301 are horizontally slidably engaged with the slide rail 5. In this embodiment, there are two slide rails 5, which are arranged one in front of the other. The slide rail 5, the first sliding thrust cylinder 1 and the second sliding thrust cylinder 101 are all mounted on the frame 6. In this embodiment, the left and right sides of the frame 6 have a platform. The first filter chamber 3, the second filter chamber 301 and the press 4 are all located between the two platforms.

[0023] Both the first filter press chamber 3 and the second filter press chamber 301 are provided with supports 8 below them. The two supports 8 are located between the two platforms, and the first filter press chamber 3 and the second filter press chamber 301 can be respectively located on the two supports 8. Figure 2 and Figure 3 As shown, in this embodiment, both supports 8 are equipped with docking bases 3.6. The docking bases 3.6 can be connected to the supports 8 by bolts or by other means, such as welding or snap-fitting, as long as the docking bases 3.6 and supports 8 are kept in a fixed state. The bottoms of the first filter press chamber 3 and the second filter press chamber 301 are detachably connected to the two docking bases 3.6 respectively. Specifically, in this embodiment, a pneumatic positioning hook pin 3.5 is installed on the docking base 3.6. The bottoms of the first filter press chamber 3 and the second filter press chamber 301 are provided with positioning holes. The first filter press chamber 3 and the second filter press chamber 301 are connected to the docking base 3.6 through the mutual connection and cooperation between the positioning holes and the pneumatic positioning hook pin 3.5. In this embodiment, the end of the positioning hole is chamfered, which can play a guiding role, so that the pneumatic positioning hook pin 3.5 on the docking base 3.6 can be smoothly inserted into the positioning hole to achieve connection and positioning. The pneumatic positioning hook in this embodiment is existing technology. A suitable pneumatic positioning hook can be selected according to the actual situation, such as the hook with publication number CN106392440B in the prior art.

[0024] In this embodiment, the output shaft of the first sliding thrust cylinder 1 and the output shaft of the second sliding thrust cylinder 101 are horizontally connected to the first filter chamber 3 and the second filter chamber 301, respectively. The first sliding thrust cylinder 1 and the second sliding thrust cylinder 101 can push the first filter chamber 3 and the second filter chamber 301 into the press 4, respectively.

[0025] In this embodiment, two sets of lifting cylinders 2 are connected to the frame. The two sets of lifting cylinders 2 are located on both sides of the slide rail 5, and the number of lifting cylinders 2 in each set matches the number of slide rails 5. The output shaft of the lifting cylinder 2 is connected to the slide rail 5, and the bottom of the cylinder body of the two sets of lifting cylinders 2 is connected to the top of the platform on both sides of the frame 6. In this embodiment, by setting the lifting cylinders 2, the first filter chamber 3 and the second filter chamber 301 can be lifted to a set height, and then pushed horizontally by the first sliding thrust cylinder 1 and the second sliding thrust cylinder 101. This can reduce the friction between the first filter chamber 3 and the second filter chamber 301 and the support 8 during the horizontal movement, thereby extending the service life of the first filter chamber 3 and the second filter chamber 301.

[0026] In this embodiment, both the first filter press chamber 3 and the second filter press chamber 301 are connected to ear seats 3.1. The ear seat 3.1 of the first filter press chamber 3 is fixed to the upper left part of the first filter press chamber 3 by bolts, and the ear seat 3.1 of the second filter press chamber 301 is fixed to the upper right part of the second filter press chamber 301 by bolts. The output shafts of the first sliding thrust cylinder 1 and the second sliding thrust cylinder 101 are respectively connected to the lugs 3.1 on the first filter chamber 3 and the second filter chamber 301. In this embodiment, the first sliding thrust cylinder 1 and the second sliding thrust cylinder 101 are rotatably connected to the first filter chamber 3 and the second filter chamber 301 by pins. In this way, when the lifting cylinder 2 lifts the slide rail 5 upward to raise the first filter chamber 3 and the second filter chamber 301, the output shafts of the first sliding thrust cylinder 1 and the second sliding thrust cylinder 101 and the lugs 3.1 can rotate, thereby avoiding the first sliding thrust cylinder 1 and the second sliding thrust cylinder 101 from hindering the normal lifting and lowering movement of the first filter chamber 3 and the second filter chamber 301.

[0027] Furthermore, such as Figure 1 As shown, in this embodiment, each support 8 is connected to a lifting cylinder 7. The top and bottom ends of the first filter chamber 3 and the second filter chamber 301 are open. Each of the first filter chamber 3 and the second filter chamber 301 is vertically slidably fitted with a lifting base plate 3.9. The lifting base plate 3.9 can seal the bottom of the filter chamber to prevent material leakage.

[0028] Combination Figure 3As shown, a lifting platform 701 is connected to the output shaft of the lifting cylinder 7. The lifting platform 701 and the output shaft of the lifting cylinder 7 can be welded together or connected and fixed by bolts, plugs, snap-fits, etc. The lifting platform 701 is detachably connected to the lifting base plate 3.9. Specifically, the lifting base plate 3.9 is designed as a two-layer structure, including an upper plate 3.91 and a lower plate 3.92. The upper plate 3.91 is located at the top of the lower plate 3.92 and is connected to it. The upper plate 3.91 is located at the top and is made of 304 stainless steel, mainly used for contacting and supporting materials. The lower layer is made of 16Mn material with a rust-proof surface treatment. The upper plate 3.91 and the lower plate 3.92 are connected by bolts. In this embodiment, the outer side of the upper plate 3.91 abuts against the inner wall of the filter press chamber, and the width of the lower plate 3.92 is smaller than the width of the upper plate 3.91, thus forming a stepped shape between the lower plate 3.92 and the upper plate 3.91.

[0029] In this embodiment, the lower plate 3.92 has four countersunk holes evenly distributed, and the lifting platform 701 has four pneumatic positioning pins 3.5 evenly distributed. The four countersunk holes on the lower plate 3.92 can sequentially engage with the four pneumatic positioning pins 3.5 on the lifting platform 701. The bottom of the countersunk holes in this embodiment is chamfered to guide the pneumatic positioning pins when they are inserted into the countersunk holes. When the pneumatic positioning pins are inserted into place, the locking tongue of the pneumatic positioning pins pops out, locking the entire lifting base plate 3.9 to the lifting platform 701.

[0030] like Figure 3 As shown, in this embodiment, a limiting base plate 3.10 is connected to the bottom of both the first filter press chamber 3 and the second filter press chamber 301. The limiting base plate 3.10 can limit the lowest position of the lowering base plate 3.9. Specifically, the limiting base plate 3.10 has a through hole in the center. In this embodiment, the lower plate 3.92 of the lowering base plate 3.9 can move into the through hole in the center of the limiting base plate 3.10, while the upper plate 3.91 is located at the top of the limiting base plate 3.10. The upper plate 3.91 is limited by the limiting base plate 3.10 and will not fall out of the filter press chamber. The limiting base plate 3.10 of the filter press chamber can ensure that the sludge will not leak during the movement of the filter press chamber.

[0031] Furthermore, in this embodiment, the inner walls of the first filter press chamber 3 and the second filter press chamber 301 have a powder-coated layer or are connected to an engineering plastic liner 3.7 by countersunk bolts. Both the powder-coated layer and the engineering plastic liner 3.7 are made of polytetrafluoroethylene or ultra-high molecular weight polyethylene. The self-lubricating and non-stick properties of these materials can greatly reduce the friction on the inner wall of the filter press, thus extending the lifespan of the filter cloth inside the filter press. Moreover, the powder-coated layer or the engineering plastic liner 3.7 makes the inner wall of the filter press smooth and prevents mud adhesion, thereby reducing friction between the lifting base plate 3.9 and the inner wall of the filter press during lifting and lowering, and consequently reducing the wear rate of the filter cloth inside the filter press.

[0032] In this embodiment, a side seam sealing gasket 3.8 is connected to the lifting base plate 3.9. Specifically, the side seam sealing gasket 3.8 is located on the upper plate 3.91 and connected to the upper plate 3.91 by screws. The edge of the side seam sealing gasket 3.8 is curved upwards and adheres to the inner side wall of the filter press chamber, which improves the sealing effect. When the filter press chamber needs to be moved, the lifting platform 701 is disengaged from the lifting base plate 3.9. At this time, the lifting base plate 3.9 descends onto the filter press chamber limiting base plate 3.10, ensuring that sludge does not fall directly from the bottom of the filter press chamber. The side seam sealing gasket 3.8, under the pressure of the sludge on it, adheres tightly to the gap between the lifting base plate 3.9 and the side wall of the filter press chamber, preventing the filter cloth or sludge from falling into the side seam and causing leakage.

[0033] Combination Figure 1 and Figure 2 As shown, rollers 3.4 are connected to the top of both the first filter chamber 3 and the second filter chamber 301. The rollers 3.4 can slide along the slide rail 5. In this embodiment, the slide rail 5 is a V-shaped slide rail 5, and the shape of the rollers 3.4 is adapted to the shape of the slide rail 5, that is, the contact position between the rollers 3.4 and the slide rail 5 is also a V-shaped structure. In this way, the rollers 3.4 are more stable when they contact the slide rail 5 and move along the slide rail 5.

[0034] The specific implementation process is as follows: the two filter press chambers are in... Figure 1 The material is fed into and discharged at the indicated locations, and is pressed inside press 4. The vertical sludge pressing equipment in this scheme adopts a feeding-pressing-discharging cycle working mode.

[0035] When operation begins, the first filter press chamber 3 and the second filter press chamber 301 are in the following positions: Figure 1 Location. The equipped cloth-laying device fills the filter press chamber with filter cloth containing sludge. During the cloth-laying process, the lifting platform 701 locks the lifting base plate 3.9.

[0036] After the material is laid, the pneumatic positioning hook 3.5 on the lifting platform 701 is disengaged from the lifting base plate 3.9, and the pneumatic positioning hook 3.5 on the docking base 3.6 is also disengaged. Then, the lifting cylinder 2 is driven to lift the slide rail 5 to the set position, thereby raising the two filter chambers and the sludge together to the ready-to-move height. After the slide rail 5 is in place, the first sliding thrust cylinder 1 extends and pushes the first filter chamber 3 into the press 4 for filtration by moving the V-shaped track roller 3.4 on the slide rail 5.

[0037] Once the first filter press chamber 3 is in position, it stops at the set position. Then, the lifting cylinder 2 is controlled to retract, resetting the slide rail 5. At this time, the second filter press chamber 301, placed in the filter press position, is connected to the docking base 3.6. The chamfered positioning hole of the second filter press chamber 301 is inserted into the pneumatic positioning hook pin 3.5 on the docking base 3.6 of the second filter press chamber 301, and the pneumatic positioning hook pin 3.5 is locked after the slide rail 5 is lowered into position.

[0038] After the first filter press chamber 3 is in place, the filter pressing operation begins. The press 4 filters the sludge according to the set process parameters. Wastewater passes through the filter cloth and exits the filter press chamber through the strip groove on the side. After the filter pressing is completed, the pneumatic positioning hook pins 3.5 on the docking base 3.6 of the first filter press chamber 3 and the second filter press chamber 301 are opened, and the lifting cylinder 2 lifts the lifting slide rail 5 to the moving ready position. The first sliding thrust cylinder 1 retracts, pulling the first filter press chamber 3 back to the inlet and outlet position.

[0039] After the first filter chamber 3 is in place, the lifting cylinder 2 lowers the slide rail 5, so that the positioning holes of the first filter chamber 3 and the second filter chamber 301 are inserted into the pneumatic positioning hook pin 3.5 on the docking base 3.6, and the pneumatic positioning hook pin 3.5 is locked after the slide rail 5 is lowered into place.

[0040] After the first filter press chamber 3 reaches its inlet / outlet position, the discharge process begins. At this time, the pneumatic positioning hook pin 3.5 on the lifting platform 701 extends into the positioning hole of the lifting floor and locks. The on-site discharge equipment removes the filter cake layer by layer. At this time, the side seam sealing gasket 3.8 seals the seam between the lifting base plate 3.9 and the powder coating layer / engineering plastic liner plate 3.7 to prevent sludge leakage.

[0041] After the sludge is unloaded, the equipment repeats the feeding and discharging process. Then, the above steps are repeated, allowing the second filter chamber 301 to enter the press 4 for pressing, while the first filter chamber 3 begins feeding. When the second filter chamber 301 finishes pressing and the first filter chamber 3 finishes feeding, the lifting cylinder 2 lifts the slide rail 5 to the set position, and the V-shaped track rollers 3.4 lift both filter chambers and the sludge together to the ready-to-move height.

[0042] When the lifting slide rail 5 is in position, the second sliding thrust cylinder 101 retracts, retracting the second filter chamber 301 back to the inlet / outlet position of the right filter chamber station; while the first sliding thrust cylinder 1 extends, pushing the first filter chamber 3 towards the filter position inside the press 4 for pressing. When the first filter chamber 3 and the second filter chamber 301 are in position respectively, they stop at the set position; then the lifting cylinder 2 is driven to retract, resetting the slide rail 5, so that the first filter chamber 3 and the second filter chamber 301 are respectively connected to the pneumatic positioning hooks 3.5 on the corresponding docking base 3.6 (the bottom of the press 4 is also equipped with a docking base 3.6, and the docking base 3.6 is also equipped with pneumatic positioning hooks 3.5, which facilitates connection and positioning with the first filter chamber 3 and the second filter chamber 301). At this time, the chamfered positioning holes at the four corners of the first filter chamber 3 and the second filter chamber 301 are inserted into the pneumatic positioning hook pins 3.5 on the corresponding docking base 3.6, and the pneumatic positioning hook pins 3.5 are locked after the slide rail 5 is lowered into place.

[0043] Thus, the second filter press 301 begins its discharge-feed process, which is the same as the discharge-feed process of the first filter press 3. Meanwhile, the first filter press 3 begins its filtration operation. The press 4 filters the sludge according to the set process parameters. By alternating between the first filter press 3 and the second filter press 301, the processing capacity of the press 4 can be doubled, the overall manufacturing cost per ton of sludge can be reduced by 25%, the filter cloth life can be doubled, and the operating cost can be reduced by 20%. Furthermore, it reduces the waiting time for feeding and discharging, improving overall work efficiency.

[0044] Example 2: The difference between this example and Example 1 is that no support 8 is provided in this example, and the lifting cylinder 7 can be directly installed at the bottom of the frame 6. In this case, the docking base 3.6 at the bottom of the first filter chamber 3 and the second filter chamber 301 can be directly connected and fixed to them. Thus, the two filter chambers can also work alternately by suspending them on the slide rail 5. However, the method in Example 2 is inferior to the method in Example 1 where a support 8 is provided to support the filter chambers, and is only considered as one possible implementation.

[0045] Example 3 Figure 4As shown, the difference between this embodiment and Embodiment 1 is that this embodiment uses an automatic control method to achieve the alternating operation of the two filter chambers. The vertical sludge pressing equipment in this embodiment also includes a controller. Limit blocks 3.2 are installed on the left side and above the first filter chamber 3 and on the right side and above the second filter chamber 301. First position sensors are installed on both sides of the press 4. The first position sensors and the lifting cylinder 7 are electrically connected to the controller. When the first filter chamber 3 and the second filter chamber 301 move into the press 4, the limit blocks 3.2 on the first and second filter chambers 301 contact the contacts of the first position sensors, triggering the first position sensors. This indicates that either the first filter chamber 3 or the second filter chamber 301 is in position. The first position sensor transmits a signal to the controller, which controls the lifting cylinder 2 to retract, resetting the slide rail 5, thereby placing the filter chamber onto the docking base 3.6 and connecting it to the docking base 3.6.

[0046] In this embodiment, a level gauge is installed on the upper part of the filter press chamber. Both the level gauge and the lifting cylinder 7 are electrically connected to the controller. When the level gauge detects a high material level in the filter press chamber, a command is given to the lifting cylinder 7 to descend. When a low material level is detected, the descent of the lifting platform 701 of the lifting cylinder 7 is stopped. Thus, as the discharge equipment removes the filter cake layer by layer, the lifting platform 701 of the lifting cylinder 7 drives the lifting base plate 3.9 to gradually rise according to the material level signal detected by the level gauge, reducing the discharge height and making unloading easier and faster.

[0047] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
