High-efficiency screw press for sludge dewatering

Abstract

The application relates to the technical field of sludge dewatering, and discloses a high-efficiency screw press for sludge dewatering, which comprises a fixed frame one, the top of the fixed frame one is fixedly connected with a driving machine, the side wall of the driving machine is fixedly connected with a machine box, and the inner wall of the machine box is fixedly connected with a fixed frame two. In view of the low pressing efficiency, a pressure receiving assembly is arranged in the equipment. The sliding obstacle block is in the gap of the spiral fan blade before use. When the spiral fan blade rotates and drives the sludge to move towards the discharge box, the spiral fan blade simultaneously drives the sliding block to slide along the inner wall of the sliding rail through the sliding obstacle block. In the process, since the sliding obstacle block is always inserted into the inner wall of the sliding rail, the gap between single positions of the sliding rail is reduced, so that the flow speed of the sludge is slowed down. Through the application of the above-mentioned assembly, the reverse flow caused by the reduction of the sliding rail spacing is effectively prevented, and the pressing effect of the equipment is affected.

Description

Technical Field

[0001] This invention relates to the field of sludge dewatering technology, specifically to a high-efficiency screw press for sludge dewatering. Background Technology

[0002] The screw conveyor is divided into three sections: a transmission section, a compression section, and a discharge section. The transmission section ensures that the material enters the equipment smoothly. In the dewatering section, the screw pitch and inner diameter of the screw blades gradually decrease, thus gradually reducing the transmission space. As the transmission space gradually decreases, the pressure on the material gradually increases, forcing the material to shrink in volume and squeeze out the water. When the material enters the discharge section of the screw conveyor, the screw conveyor will apply an axial thrust to the material and push it out of the discharge port.

[0003] One method of dewatering by reducing the pitch and inner diameter of the screw blades to increase the extrusion pressure on the material has the following drawbacks: due to the high fluidity of the sludge itself, the sludge will flow and depressurize after being compressed, resulting in a decrease in dewatering efficiency. To address these issues, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a high-efficiency screw press for sludge dewatering, including a fixed frame one, a drive motor fixedly connected to the top of the fixed frame one, a machine housing fixedly connected to the side wall of the drive motor, a fixed frame two fixedly connected to the inner wall of the machine housing, a filter screen fixedly connected to the inner wall of the fixed frame two, a feed end connected through the top of the filter screen, and a collection pipe connected through the bottom of the machine housing, and further including:

[0005] The power mechanism is fixedly connected to the side wall of the drive unit and is used to provide power for the operation of the equipment.

[0006] The pressurizing mechanism is slidably connected to the inner wall of the power mechanism. It is used to insert into the sludge when the equipment rotates, thus restricting the flow of the sludge.

[0007] The control mechanism is fixedly connected to the outer wall of the booster mechanism and is used to control the sliding distance of the booster mechanism.

[0008] Before use, the fixing frame is first fixed in the required position, and it is ensured that the external sludge can be poured into the inside of the machine through the feed end. Then, the drive machine drives the power mechanism to run and squeeze out the excess water in the sludge.

[0009] Preferably, the power mechanism includes:

[0010] The drive assembly is fixedly connected to the side wall of the drive unit by an extrusion component;

[0011] The extrusion component includes a drive rod fixedly connected to the outer wall of the output shaft of the drive unit, and a spiral fan blade is fixedly connected to the outer wall of the drive rod;

[0012] The support assembly is fixedly connected to the outer wall of the second fixing frame by fasteners;

[0013] The fasteners include a fixed frame three that is fixedly connected to the outer wall of the fixed frame two, and a sliding rail is connected through the outer wall of the fixed frame three;

[0014] The closer the spiral fan blades are to the drive motor, the larger the gap becomes. This allows the sludge to move away from the drive motor as the drive motor rotates the drive rod and the spiral fan blades. As the gap between the spiral fan blades narrows, the sludge between the gaps is squeezed, removing excess water.

[0015] Preferably, the booster mechanism includes:

[0016] The pressure-bearing component is slidably connected to the inner wall of the sliding track via a tension member;

[0017] The pulling component includes a sliding block that is slidably connected to the inner wall of the sliding track, and a sliding obstruction block is slidably connected to the inner wall of the sliding block;

[0018] The limiting component is fixedly connected to the side wall of the sliding obstruction block by a spring component;

[0019] The spring component includes a return spring that is fixedly connected to the side wall of the sliding stop block;

[0020] During the sliding process of the pressure-bearing component, the sliding obstruction block will be displaced by pressure and inserted into the gap of the sliding track to limit the flow speed of the sludge.

[0021] Preferably, the control mechanism includes:

[0022] The contact component is fixedly connected to the outer wall of the sliding block via a support member.

[0023] The support includes a support frame fixedly connected to the side wall of the sliding block, and a rotating rod rotatably connected to the inner wall of the support frame;

[0024] Anti-blocking component, the anti-blocking component is fixedly connected to the inner wall of the sliding track by a limiting member;

[0025] The limiting component includes a partition plate fixedly connected to the inner wall of the sliding track;

[0026] When the sliding block slides along the inner wall of the sliding track through the sliding obstruction block, the rotating rod will drive the contact assembly to move, releasing the restriction on the arc surface limiting block, so that the return spring drives the sliding obstruction block to reset.

[0027] Preferably, the drive assembly includes an outlet fixedly connected to the end of the chassis away from the drive motor, and a discharge box fixedly connected to the side wall of the chassis;

[0028] The spiral fan blades remove most of the water from the sludge, which then enters the inner wall of the discharge box through the discharge outlet to discharge impurities. The wastewater falls onto the inner wall of the collection pipe and is discharged outward from the side pipe.

[0029] Preferably, the support assembly includes a fixing block 1 fixedly connected to the inner wall of the sliding track, and an inclined panel is fixedly connected to the side wall of the fixing block 1.

[0030] When the sliding block is resetting and sliding, it will cause the pressure component to contact the inclined surface of the inclined panel, and force the sliding block to move outward.

[0031] Preferably, the pressure-bearing component includes a roller fixedly connected to the top of the sliding block, and a tension spring fixedly connected to the side wall of the sliding block, with the end of the tension spring away from the sliding block fixedly connected to the inner wall of the sliding track.

[0032] When the sliding block is resetting, the sliding obstruction block will cause the roller to contact the inclined surface of the inclined panel, and the roller will cause the sliding obstruction block to move outward.

[0033] Preferably, the limiting component includes arc-shaped limiting blocks slidably connected to both sides of the sliding obstruction block, and a spring is fixedly connected to the side wall of the arc-shaped limiting block;

[0034] When the sliding obstruction block moves outward, the arc-shaped limiting block will contact the inner wall of the contact component, and the contact component will restrict the movement of the arc-shaped limiting block and the sliding obstruction block. During this process, the return spring will be in a straightened state.

[0035] Preferably, the contact assembly includes a sliding rod slidably connected to the inner wall of the sliding block, a fixed rod two fixedly connected to the side wall of the sliding rod, the inner wall of the through hole of the rotating rod slidably connected to the inner wall of the fixed rod two, and an arc-shaped spring fixedly connected to the end of the rotating rod away from the fixed rod two.

[0036] When the spiral fan blades rotate, the inner wall of the gap in the spiral fan blades contacts the outer wall of the sliding obstruction block. This causes the sliding obstruction block to move synchronously toward the discharge box. During this process, the rotating rod will contact the side wall of the partition, forcing the rotating rod to move the fixed rod and the sliding rod away from the arc-shaped limiting block.

[0037] Preferably, the anti-blocking component includes a telescopic plate one fixedly connected to the inner wall of the sliding track, the other end of the telescopic plate one being fixedly connected to the side wall of the sliding block, and a telescopic plate two fixedly connected to the inner wall of the sliding track, the other end of the telescopic plate two being fixedly connected to the side wall of the sliding block.

[0038] During the sliding process of the sliding block, telescopic plate one and telescopic plate two will extend and retract accordingly.

[0039] The present invention has the following beneficial effects:

[0040] (1) In view of the problem of low pressing efficiency, the present invention has a pressure-bearing component inside the equipment. The sliding obstruction block is located inside the gap of the spiral fan blade before use. When the spiral fan blade rotates and drives the sludge to move towards the discharge box, the spiral fan blade drives the sliding block to slide along the inner wall of the sliding track through the sliding obstruction block. During this process, since the sliding obstruction block is always inserted into the inner wall of the sliding track, the gap of a single position of the sliding track is reduced, thereby slowing down the flow speed of the sludge. Through the application of the above component, the backflow caused by the reduction of the sliding track gap is effectively prevented, which would affect the pressing effect of the equipment.

[0041] (2) In this invention, the sliding block slides to Figure 5 When the position of U is in the middle, such as Figure 7 At this point, the upward-curved end of the rotating rod will contact the side wall of the partition. As the sliding block moves, the rotating rod, under pressure, will drive the fixed rod and the sliding rod to slide around the support frame, causing the sliding rod to move away from the arc-shaped limiting block. At this point, the sliding rod no longer restricts the arc-shaped limiting block, and the return spring generates a contraction force, causing the sliding obstruction block to penetrate deeper into the inner wall of the sliding block. At this point, the tension spring will release the compressed mechanical power, forcing the sliding block to return to its original position. When the sliding block returns to its original position, the sliding obstruction block will drive the roller to contact the inclined surface of the inclined panel. The roller will drive the sliding obstruction block to move outward, and at this point, the return spring will extend and accumulate mechanical power. Through the application of the above components, the autonomous operation of the equipment is achieved.

[0042] (3) The present invention utilizes the feature of the sliding block sliding along the inner wall of the sliding track and sets up an anti-blocking component inside the equipment. During the sliding process of the sliding block, the first telescopic plate and the second telescopic plate will expand and contract accordingly and block the end of the sliding track near the spiral fan blade, so as to prevent the sludge inside the machine box from being sprayed out from the inside of the sliding track due to high pressure, which would affect the internal pressure of the equipment.

[0043] (4) In this invention, when the sliding block reaches the inclined plate position, if the spiral fan blades obstruct the outward movement of the sliding block, the roller will be unable to slide along the inclined surface of the inclined plate. Figure 10 As the fan blades rotate, the restriction of the fan blades on the sliding block will gradually decrease and eventually lose its restriction on the sliding block. At this time, the tension spring will cause the sliding block to continue to contract, so that the roller will drive the sliding block into the inner wall of the fan blade along the inclined plate, ensuring that the sliding block can be accurately inserted into the inner wall of the fan blade during operation.

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Example 1, please refer to Figures 1-5 This invention relates to a high-efficiency screw press for sludge dewatering, comprising a fixed frame 13, a drive motor 14 fixedly connected to the top of the fixed frame 13, a housing 15 fixedly connected to the side wall of the drive motor 14, a fixed frame 16 fixedly connected to the inner wall of the housing 15, a filter screen 17 fixedly connected to the inner wall of the fixed frame 16, a feed end 18 penetratingly connected to the top of the filter screen 17, and a collection pipe 19 penetratingly connected to the bottom of the housing 15, and further comprising:

[0059] Power mechanism 1 is fixedly connected to the side wall of drive motor 14 and is used to provide power for the operation of the equipment;

[0060] The booster mechanism 2 is slidably connected to the inner wall of the power mechanism 1, and is used to insert the booster mechanism 2 into the sludge when the equipment rotates to restrict the flow of the sludge.

[0061] Control mechanism 3 is fixedly connected to the outer wall of pressurizing mechanism 2 and is used to control the sliding distance of pressurizing mechanism 2;

[0062] Before use, fix the bracket 13 in the required position and ensure that the external sludge can be poured into the inside of the housing 15 through the feed end 18. The closer the spiral fan blade 112 is to the drive motor 14, the larger the gap is. After the sludge enters the inner wall of the housing 15, as the drive motor 14 drives the drive rod 111 and the spiral fan blade 112 to rotate, the sludge will move away from the drive motor 14. At the same time, the gap of the spiral fan blade 112 narrows, squeezing the sludge between the gaps of the spiral fan blade 112 and removing excess water.

[0063] Before use, the fixing frame 13 is fixed in the required position, and it is ensured that the external sludge can be injected into the inside of the casing 15 through the feed end 18. Then, the drive motor 14 drives the power mechanism 1 to run and squeeze out the excess water in the sludge.

[0064] Power mechanism 1 includes:

[0065] Drive assembly 11 is fixedly connected to the side wall of drive unit 14 by an extrusion member;

[0066] The extrusion component includes a drive rod 111 fixedly connected to the outer wall of the output shaft of the drive motor 14, and a spiral fan blade 112 fixedly connected to the outer wall of the drive rod 111.

[0067] Support component 12 is fixedly connected to the outer wall of the second fixing frame 16 by fasteners;

[0068] The fasteners include a fixed frame three 121 fixedly connected to the outer wall of the fixed frame two 16, and a sliding rail 122 is connected through the outer wall of the fixed frame three 121;

[0069] The closer the spiral fan blades 112 are to the drive motor 14, the larger the gap is. This allows the sludge to move away from the drive motor 14 as the drive motor 14 drives the drive rod 111 and the spiral fan blades 112 to rotate. As the gap between the spiral fan blades 112 narrows, the sludge between the gaps in the spiral fan blades 112 is squeezed, removing excess water.

[0070] The booster mechanism 2 includes:

[0071] The pressure-bearing component 21 is slidably connected to the inner wall of the sliding track 122 via a tension member;

[0072] The pulling component includes a sliding block 211 that is slidably connected to the inner wall of the sliding track 122, and a sliding obstruction block 212 is slidably connected to the inner wall of the sliding block 211;

[0073] Limiting component 22 is fixedly connected to the side wall of sliding obstruction block 212 by a spring member;

[0074] The spring component includes a return spring 221 that is fixedly connected to the side wall of the sliding stop block 212;

[0075] During the sliding process of the pressure-bearing component 21, the sliding obstruction block 212 will be displaced by the pressure and inserted into the gap of the sliding track 122 to limit the flow speed of the sludge.

[0076] Control mechanism 3 includes:

[0077] Contact component 31 is fixedly connected to the outer wall of sliding block 211 by a support member;

[0078] The support includes a support frame 313 fixedly connected to the side wall of the sliding block 211, and a rotating rod 314 rotatably connected to the inner wall of the support frame 313;

[0079] Anti-blocking component 32 is fixedly connected to the inner wall of sliding track 122 by a limiting member;

[0080] The limiting component includes a partition 323 fixedly connected to the inner wall of the sliding track 122;

[0081] When the sliding block 211 slides along the inner wall of the sliding track 122 via the sliding obstruction block 212, the rotating rod 314 will drive the contact component 31 to move, releasing the restriction on the arc surface restriction block 222, so that the reset spring 221 drives the sliding obstruction block 212 to reset.

[0082] Example 2, please refer to Figures 3-10 The present invention is a high-efficiency screw press for sludge dewatering. Based on Example 1, the drive assembly 11 includes an outlet 113 fixedly connected to the end of the housing 15 away from the drive motor 14, and a discharge box 114 fixedly connected to the side wall of the housing 15.

[0083] The clearance between the spiral fan blade 112 and the drive motor 14 is relatively large, such as Figure 5 The state of G is such that the gap near the discharge box 114 is smaller, presenting as... Figure 5 In the state of H, the device also has two sets of sliding obstruction blocks 212 inside. The width of the set closer to the drive motor 14 is smaller than the width of G, but... Figure 5 The width of position U is equal to that of position H; while the width of the group closest to the discharge box 114 is smaller than that of position U, but equal to the width of position H, and the two groups operate in the same way.

[0084] The spiral fan blades 112 remove most of the water from the sludge and then enter the inner wall of the discharge box 114 through the discharge port 113 to complete the discharge of impurities. The sewage will fall onto the inner wall of the collection pipe 19 and be discharged outward from the side pipe.

[0085] The support assembly 12 includes a fixing block 123 fixedly connected to the inner wall of the sliding track 122, and an inclined panel 124 fixedly connected to the side wall of the fixing block 123.

[0086] To address the issue of low pressing efficiency, a pressure-bearing component 21 is installed inside the equipment. The sliding obstruction block 212 is positioned inside the gap of the spiral fan blade 112 before use. When the spiral fan blade 112 rotates and moves the sludge towards the discharge box 114, the spiral fan blade 112 simultaneously drives the sliding block 211 to slide along the inner wall of the sliding track 122 via the sliding obstruction block 212. During this process, because the sliding obstruction block 212 is always inserted into the inner wall of the sliding track 122, the gap at a single position of the sliding track 122 is reduced, thereby slowing down the flow rate of the sludge. Through the application of this component, backflow caused by the reduced spacing of the sliding tracks 122 is effectively prevented, thus preventing the pressing effect of the equipment from being affected.

[0087] When the sliding block 211 is reset and sliding, it will cause the pressure component 21 to contact the inclined surface of the inclined panel 124, and force the sliding blocking block 212 to move outward.

[0088] The pressure-bearing component 21 includes a roller 213 fixedly connected to the top of the sliding block 212, and a tension spring 214 fixedly connected to the side wall of the sliding block 211. The end of the tension spring 214 away from the sliding block 211 is fixedly connected to the inner wall of the sliding track 122.

[0089] Taking advantage of the characteristic that the sliding block 211 slides along the inner wall of the sliding track 122, an anti-blocking component 32 is installed inside the equipment. During the sliding of the sliding block 211, the first telescopic plate 321 and the second telescopic plate 322 will expand and contract accordingly, and block the end of the sliding track 122 near the spiral fan blade 112, so as to prevent the sludge inside the casing 15 from being sprayed out from the inside of the sliding track 122 due to high pressure, which would affect the internal pressure of the equipment.

[0090] When the sliding block 211 is reset and moving, the sliding obstruction block 212 will drive the roller 213 to contact the inclined surface of the inclined panel 124, and the roller 213 will drive the sliding obstruction block 212 to move outward.

[0091] The limiting component 22 includes arc-shaped limiting blocks 222 that are slidably connected to both sides of the sliding blocking block 212, and a spring 223 is fixedly connected to the side wall of the arc-shaped limiting block 222.

[0092] Taking advantage of the characteristic that the sliding obstruction block 212 follows the sliding track 122, a control mechanism 3 is provided inside the equipment. When the sliding obstruction block 212 is in the extended state, the sliding rod 311 restricts the reset of the sliding obstruction block 212 through the arc surface limiting block 222. At this time, the reset spring 221 will extend and accumulate mechanical power.

[0093] When the sliding obstruction block 212 moves outward, the arc surface restriction block 222 will contact the inner wall of the contact component 31, and the contact component 31 will restrict the movement of the arc surface restriction block 222 and the sliding obstruction block 212. During this process, the return spring 221 will be in a straightened state.

[0094] The contact assembly 31 includes a sliding rod 311 slidably connected to the inner wall of the sliding block 211, a fixed rod 312 fixedly connected to the side wall of the sliding rod 311, the inner wall of the through hole of the rotating rod 314 slidably connected to the inner wall of the fixed rod 312, and an arc spring 315 fixedly connected to the end of the rotating rod 314 away from the fixed rod 312.

[0095] After the spiral fan blades 112 remove most of the water from the sludge, the sludge will enter the inner wall of the discharge box 114 through the discharge port 113 to complete the discharge of impurities, while the sewage will fall onto the inner wall of the collection pipe 19 and be discharged outward from the side pipe.

[0096] When the spiral fan blade 112 rotates, the inner wall of the gap of the spiral fan blade 112 contacts the outer wall of the sliding obstruction block 212, which causes the sliding obstruction block 212 to drive the sliding block 211 to move synchronously towards the discharge box 114. During this process, the rotating rod 314 will contact the side wall of the partition 323, forcing the rotating rod 314 to drive the fixed rod 312 and the sliding rod 311 away from the arc surface restriction block 222.

[0097] The anti-blocking component 32 includes a telescopic plate 321 fixedly connected to the inner wall of the sliding track 122, the other end of the telescopic plate 321 being fixedly connected to the side wall of the sliding block 211, and a telescopic plate 322 fixedly connected to the inner wall of the sliding track 122, the other end of the telescopic plate 322 being fixedly connected to the side wall of the sliding block 211.

[0098] Slide the slider 211 to Figure 5 When the position of U is in the middle, such as Figure 7At this time, the upward-curved end of the rotating rod 314 will contact the side wall of the partition 323. As the sliding block 211 moves, the rotating rod 314, under pressure, will drive the fixed rod 312 and the sliding rod 311 to slide around the support frame 313, causing the sliding rod 311 to move away from the arc surface limiting block 222. At this time, the sliding rod 311 no longer restricts the arc surface limiting block 222, and the return spring 221 generates a contraction force, causing the sliding obstruction block 212 to extend into the inner wall of the sliding block 211. At this time, the tension spring 214 will release the compressed mechanical power, forcing the sliding block 211 to return to its original position. When the sliding block 211 returns to its original position, the sliding obstruction block 212 will drive the roller 213 to contact the inclined surface of the inclined panel 124. The roller 213 will drive the sliding obstruction block 212 to move outward. At this time, the return spring 221 will extend and accumulate mechanical power. Through the application of the above components, the autonomous operation of the equipment is realized.

[0099] During the sliding process of the sliding block 211, the telescopic plate 321 and the telescopic plate 322 will extend and retract accordingly.

[0100] One specific application of this embodiment is as follows: Before use, fix the fixing frame 13 in the required position and ensure that the external sludge can be injected into the inside of the casing 15 through the feed end 18. The gap of the spiral fan blade 112 is larger as it is closer to the drive motor 14. After the sludge enters the inner wall of the casing 15, as the drive motor 14 drives the drive rod 111 and the spiral fan blade 112 to rotate, the sludge will move away from the drive motor 14. At the same time, the gap of the spiral fan blade 112 narrows, squeezing the sludge between the gaps of the spiral fan blade 112 and removing excess water.

[0101] In addition, the gap between the spiral fan blade 112 and the drive motor 14 is relatively large, such as Figure 5 The state of G is such that the gap near the discharge box 114 is smaller, presenting as... Figure 5 In the state of H, the device also has two sets of sliding obstruction blocks 212 inside. The width of the set closer to the drive motor 14 is smaller than the width of G, but... Figure 5 The width of position U is equal to that of position H; while the width of the group closest to the discharge box 114 is smaller than that of position U, but equal to the width of position H, and the two groups operate in the same way.

[0102] To address the issue of low pressing efficiency, a pressure-bearing component 21 is installed inside the equipment. The sliding obstruction block 212 is positioned inside the gap of the spiral fan blade 112 before use. When the spiral fan blade 112 rotates and moves the sludge towards the discharge box 114, the spiral fan blade 112 simultaneously drives the sliding block 211 to slide along the inner wall of the sliding track 122 via the sliding obstruction block 212. During this process, because the sliding obstruction block 212 is always inserted into the inner wall of the sliding track 122, the gap at a single position of the sliding track 122 is reduced, thereby slowing down the flow rate of the sludge. Through the application of this component, backflow caused by the reduced spacing of the sliding tracks 122 is effectively prevented, thus preventing the pressing effect of the equipment from being affected.

[0103] Taking advantage of the characteristic that the sliding obstruction block 212 follows the sliding track 122, a control mechanism 3 is provided inside the equipment. When the sliding obstruction block 212 is in the extended state, the sliding rod 311 restricts the reset of the sliding obstruction block 212 through the arc surface limiting block 222. At this time, the reset spring 221 will extend and accumulate mechanical power.

[0104] While sliding block 211 slides to Figure 5 When the position of U is in the middle, such as Figure 7 At this time, the upward-curved end of the rotating rod 314 will contact the side wall of the partition 323. As the sliding block 211 moves, the rotating rod 314, under pressure, will drive the fixed rod 312 and the sliding rod 311 to slide around the support frame 313, causing the sliding rod 311 to move away from the arc surface limiting block 222. At this time, the sliding rod 311 no longer restricts the arc surface limiting block 222, and the return spring 221 generates a contraction force, causing the sliding obstruction block 212 to extend into the inner wall of the sliding block 211. At this time, the tension spring 214 will release the compressed mechanical power, forcing the sliding block 211 to return to its original position. When the sliding block 211 returns to its original position, the sliding obstruction block 212 will drive the roller 213 to contact the inclined surface of the inclined panel 124. The roller 213 will drive the sliding obstruction block 212 to move outward. At this time, the return spring 221 will extend and accumulate mechanical power. Through the application of the above components, the autonomous operation of the equipment is realized.

[0105] Taking advantage of the characteristic that the sliding block 211 slides along the inner wall of the sliding track 122, an anti-blocking component 32 is installed inside the equipment. During the sliding of the sliding block 211, the first telescopic plate 321 and the second telescopic plate 322 will expand and contract accordingly, and block the end of the sliding track 122 near the spiral fan blade 112, so as to prevent the sludge inside the casing 15 from being sprayed out from the inside of the sliding track 122 due to high pressure, which would affect the internal pressure of the equipment.

[0106] Finally, after the spiral fan blades 112 remove most of the water from the sludge, it will enter the inner wall of the discharge box 114 through the discharge port 113 to complete the discharge of impurities, while the sewage will fall onto the inner wall of the collection pipe 19 and be discharged outward from the side pipe.
