[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a sludge thickener extrusion device, including a housing 1. The top of the housing 1 has an extrusion groove. A cylinder 2 is installed inside the extrusion groove of the housing 1. One end of the cylinder 2 is connected to a push plate 3 for extruding sludge. The bottom of the housing 1 has a drainage trough 4 for collecting wastewater. A net 5 is installed at the top of the drainage trough 4. A drainage pipe 6 that penetrates the housing 1 is connected to the bottom of the drainage trough 4. A wastewater tank 7 is installed at the bottom of the drainage pipe 6. In use, the sludge to be extruded can be poured into the housing 1. Then, the cylinder 2 pushes the push plate 3 to move. The movement of the push plate 3 will extrude the sludge inside the housing 1. At the same time, the water in the sludge will flow into the drainage trough 4 when it is extruded, and then flow into the wastewater tank 7 through the drainage pipe 6 at the bottom of the drainage trough 4. The sludge can be intercepted in the housing 1 by the net 5, thereby extruding and removing the water in the sludge.

[0028] exist Figures 2-4 In the middle: the push plate 3 has a cavity 8 inside, a connection hole 23 is provided on one side of the cavity 8, a drain hole 9 is connected through the bottom of the cavity 8, and a filter screen 10 for filtering sludge is provided on the side of the push plate 3 near the connection hole 23.

[0029] exist Figures 2-4 In the middle: When the push plate 3 moves, it will squeeze the sludge. Some of the water in the sludge will flow into the cavity 8 through the connecting hole 23 on one side of the push plate 3, and then flow out of the cavity 8 through the drain hole 9 and flow into the drain trough 4 at the bottom, thereby accelerating the discharge speed of water in the sludge.

[0030] exist Figure 2 , Figure 6 and Figure 7 In the middle: both ends of the filter screen 10 are equipped with fixing blocks 11. The fixing blocks 11 are installed on one side of the push plate 3. The filter screen 10 is slidably connected to the two sets of fixing blocks 11. A protrusion 12 is installed on one side of the filter screen 10. A movable block 13 is sleeved on one end of the protrusion 12. A telescopic block 14 is provided on the side of the movable block 13 near the fixing block 11. The telescopic block 14 can extend and retract along the movable groove on one side of the fixing block 11. The telescopic block 14 can drive the movable block 13 to move. A first spring 15 is provided between the telescopic block 14 and the movable groove of the fixing block 11.

[0031] exist Figure 2 , Figure 6 and Figure 7 In the middle: the filter screen 10 on one side of the connecting hole 23 can filter the water in the sludge. At the same time, the movable block 13 can be pulled, so that the movable block 13 moves to one side of the fixed block 11 through the telescopic block 14, and the first spring 15 in the movable groove of the fixed block 11 is stretched. When the movable block 13 moves to one side, it will separate from the protrusion 12 on one side of the filter screen 10, so that the protrusion 12 moves out of the through hole of the movable block 13. Without the movable block 13 and the protrusion 12 limiting the filter screen 10, the filter screen 10 can be slidably removed from between the two sets of fixed blocks 11, so as to facilitate the cleaning and replacement of the filter screen 10.

[0032] Conversely, the filter screen 10 can be slid between the two sets of fixed blocks 11; when the protrusion 12 on one side of the filter screen 10 is aligned with the through hole in the middle of the movable block 13, the movable block 13 is released, and then the first spring 15 will drive the movable block 13 to move in the opposite direction through the telescopic block 14, so that the movable block 13 can be fitted onto the outside of the protrusion 12. Through the cooperation of the movable block 13 and the protrusion 12, the filter screen 10 can be stably installed on one side of the push plate 3, thereby separating the water in the sludge.

[0033] exist Figure 2 In the middle: A connecting groove is provided on the top of the box body 1. A second spring 16 is installed inside the connecting groove. A baffle 17 that passes through the connecting groove is connected to one side of the second spring 16.

[0034] exist Figure 2 In the middle: When squeezing sludge, the baffle 17 on the top of the box 1 can be pulled to one side, so that the second spring 16 is stretched and the baffle 17 covers the top of the box 1 to prevent sludge from overflowing from the top of the box 1 when squeezing sludge.

[0035] exist Figure 1 and Figure 3In the middle: A locking block 18 is inserted into the bottom of the baffle 17. The bottom of the baffle 17 has a slot that matches the size of the locking block 18, and the locking block 18 can be engaged with the slot at the bottom of the baffle 17. A rotating block 19 is provided at the bottom of the locking block 18. A groove is provided at the top of the box 1. The locking block 18 can move up and down along the groove of the box 1 through the rotating block 19. The middle of the rotating block 19 is connected to the groove of the box 1 through a rotating shaft. A third spring 20 is provided between the bottom of the rotating block 19 and the groove of the box 1.

[0036] exist Figure 2 and Figure 5 In the middle: When the baffle 17 moves to one side, it will squeeze the locking block 18 in the groove of the box 1. The locking block 18 will move downward when squeezed, and squeeze the rotating block 19 in the groove of the box 1, causing the rotating block 19 to rotate. When the rotating block 19 rotates, it will squeeze the third spring 20 at the bottom. When the baffle 17 continues to move, and the groove at the bottom of the baffle 17 is aligned with the locking block 18, the rotating block 19 will rotate in the opposite direction through the reset action of the third spring 20, thereby pushing the locking block 18 upward, so that the locking block 18 is engaged in the groove at the bottom of the baffle 17, thereby fixing the baffle 17.

[0037] exist Figure 2 and Figure 5 In the middle: A connecting block 21 is also provided at the bottom of the other end of the rotating block 19, and a connecting rod 22 that penetrates the groove of the box body 1 is installed on the top of the connecting block 21.

[0038] exist Figure 2 and Figure 5 In the middle: When it is necessary to open the baffle 17, simply pull the connecting rod 22 upward. Pulling the connecting rod 22 upward will cause the rotating block 19 to rotate through the connecting block 21. When the rotating block 19 rotates, it will not squeeze the locking block 18. Without being squeezed, the locking block 18 will move downward by gravity and separate from the groove at the bottom of the baffle 17. At this time, the baffle 17 will retract into the connecting groove of the housing 1 through the reset action of the second spring 16, thus making it easy to open the baffle 17.
