DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without making creative efforts fall within the protection scope of the utility model.

[0023] In the description of the utility model, it is necessary to explain that, unless explicitly defined and limited, the terms "mounting", "connection" and "connection" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For the ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0024] Embodiment 1:

[0025] The embodiment provides a sludge filter pressing dewatering equipment, specifically as Figure 1 、 Figure 2As shown, the system includes a collection tank 101, on which a partition 102 is provided, dividing the collection tank 101 into a sludge collection area 11 and a wastewater collection area 12. A support 116 is installed on the collection tank 101, and a filter press cylinder, a drive motor 107, and a transmission shaft are installed on the support 116. The filter press cylinder is provided with filter holes, a feed inlet, and a discharge outlet, and a feed hopper 103 is provided on the feed inlet. A spiral blade 108 is installed on the transmission shaft, and the pitch of the spiral blade 108 decreases from the feed inlet end to the discharge outlet end. The drive motor 107 is connected to the transmission shaft. A discharge control unit is also provided on the support 116, which is used to control the opening and closing of the discharge outlet of the filter press cylinder.

[0026] Sludge water is introduced into the feed hopper 103 and then flows from the feed hopper 103 into the filter press. When the drive motor 107 is started, the drive shaft begins to rotate. At this time, the spiral blade 108 gradually pushes the sludge water towards the discharge port. During this process, water begins to be discharged from the fine filter holes on the filter press and drips into the wastewater collection area 12. As the pitch of the spiral blade 108 gradually decreases along the direction of sludge water pushing, the sludge begins to be gradually squeezed, thereby improving the sludge-water separation rate. When the sludge reaches the discharge port, after the water has been fully squeezed out, the discharge control unit opens the discharge port of the filter press. As the sludge is continuously pushed by the spiral blade 108, the sludge with the squeezed water is squeezed out from the discharge port and falls into the sludge collection area 11 for collection.

[0027] By setting the spiral blade 108 with variable pitch and the discharge control unit for sealing the discharge port, the sludge water is fully squeezed in the filter press cylinder; and it can operate continuously. The sludge squeezing operation can also be carried out synchronously during the discharge at the discharge port, that is, there is no need to stop the machine to remove the sludge and then start the machine to perform sludge squeezing operation, which greatly improves the operating efficiency.

[0028] Example 2:

[0029] This embodiment further expands the material discharge control unit based on the above embodiment, specifically as follows: Figures 3-5 As shown, the discharge control unit includes a support cylinder 106, a spring 114, a sealing plate connecting rod 120, and a sealing plate 112; the transmission shaft includes an output shaft 122, an adjusting shaft 113, and a spiral blade shaft 121. The spiral blade 108 is mounted on the spiral blade shaft 121, the output shaft 122 is mounted on the output end of the drive motor 107, and the adjusting shaft 113 is slidably connected to the spiral blade shaft 121 and the output shaft 122 respectively; a spring 114 is provided between the adjusting shaft 113 and the filter press cylinder, the sealing plate 112 is mounted on the sealing plate connecting rod 120, the sealing plate connecting rod 120 cooperates with the adjusting shaft 113, and the sealing plate 112 cooperates with the discharge port of the filter press cylinder.

[0030] When sludge needs to be discharged from the discharge port, the adjusting shaft 113 is moved closer to the spiral blade shaft 121 by overcoming the elastic force of the spring 114. At this time, the sealing plate connecting rod 120 starts to rotate, causing the sealing plate 112 to disengage from the filter press cylinder, thus opening the discharge port. After the discharge is completed, the adjusting shaft 113 is released, and under the elastic force of the spring 114, the adjusting shaft 113 automatically returns to its original position and moves closer to the output shaft 122. At this time, the sealing plate connecting rod 120 rotates, causing the sealing plate 112 to block the discharge port, preventing the sludge from being discharged further. When the sealing plate 112 blocks the discharge port, the pressure on the sludge in the filter press cylinder increases as the spiral blade 108 continues to advance, thus effectively filtering out water. The intermittent opening and closing of the sealing plate 112 creates periodic squeezing of the wastewater in the filter press cylinder, ensuring that the wastewater filtration rate meets the standards and that the moisture content of the subsequently discharged sludge is within acceptable limits.

[0031] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0032] Example 3:

[0033] This embodiment further extends the above embodiment, specifically as follows: Figures 3-5 As shown, a discharge control disk 111 is installed on the adjusting shaft 113, and an arc-shaped protrusion is provided on the discharge control disk 111. A top block 115 is installed on the bracket 116, and the top block 115 cooperates with the discharge control disk 111.

[0034] Each time the discharge control disc 111 rotates, the protrusion on the discharge control disc 111 will contact the top block 115 once. When the top block 115 contacts the protrusion, the discharge control disc 111 will push the adjusting shaft 113 closer to the spiral blade shaft 121. When the top block 115 does not contact the protrusion, under the elastic force of the spring 114, the top block 115 will press against the air area of ​​the discharge control disc 111, at which time the adjusting shaft 113 will approach the output shaft 122. If the discharge control disc 111 is fixedly installed on the adjusting shaft 113, the discharge control disc 111 will rotate synchronously with the adjusting shaft 113. If the discharge control disc 111 is rotatably connected to the adjusting shaft 113, then an external force is needed to rotate the discharge control disc 111. Both of these methods can achieve the effect of the discharge control disc 111 driving the adjusting shaft 113 to move. By setting the discharge control disc 111, the distance that the adjusting shaft 113 moves laterally each time is equal, that is, the opening of the sealing plate 112 is fixed, avoiding the problem of the opening being too small or too large due to manual opening of the sealing plate 112.

[0035] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0036] Example 4:

[0037] The embodiment is further extended on the basis of the above-mentioned embodiment, and specifically as shown in Figures 3-5 When the discharge control disc 111 is rotationally connected to the adjusting shaft 113, the first gear 117 is installed on the output shaft 122, the second gear 119 is rotationally connected to the bracket 116, the third gear 118 is installed on the second gear 119, the tooth ring 110 is installed on the discharge control disc 111, the tooth ring 110 is engaged with the third gear 118, and the first gear 117 is engaged with the second gear 119.

[0038] The first gear 117 is driven to rotate by the output shaft 122, the second gear 119 is driven by the first gear 117, the second gear 119 and the third gear 118 are coaxially and synchronously rotated, the third gear 118 drives the tooth ring 110 to rotate, and the tooth ring 110 drives the discharge control disc 111 to rotate, so that the power of the driving motor 107 is introduced and supplied to the discharge control disc 111 for use, without the need to additionally set an extra driving source.

[0039] The other parts of the embodiment are the same as those of the above-mentioned embodiment, and will not be described herein again.

[0040] Embodiment 5

[0041] The embodiment is further extended on the basis of the above-mentioned embodiment, and specifically as shown in Figure 4 The transmission ratio of the first gear 117 to the second gear 119 is greater than 1, and the transmission ratio of the third gear 118 to the tooth ring 110 is greater than 1.

[0042] Through the above-mentioned setting, the rotation speed of the discharge control disc 111 is far less than the rotation speed of the adjusting shaft 113, that is, the blocking plate 112 is opened once after the spiral blade 108 pushes and extrudes the sludge for a period of time; compared with the case that the blocking plate 112 is opened once after the spiral blade 108 rotates one circle; the setting gives the sludge extrusion enough time and improves the dewatering rate of the sludge. Moreover, by replacing the first gear 117 and the second gear 119, the transmission ratio can be changed to control the extrusion time of the sludge.

[0043] The other parts of the embodiment are the same as those of the above-mentioned embodiment, and will not be described herein again.

[0044] Embodiment 6

[0045] The embodiment is further extended on the basis of the above-mentioned embodiment, and specifically as shown in Figure 1 , Figure 2 The filter cylinder includes a drainage cylinder 104, a sludge discharge cylinder 105, and an end plate 109. The drainage cylinder 104 is provided with filter holes, and the feed inlet is located on the drainage cylinder 104. The sludge discharge cylinder 105 is not provided with filter holes, and the discharge port is located on the sludge discharge cylinder 105. The end plate 109 is used to block the two ends of the filter cylinder.

[0046] By segmenting the filter cylinder, the installation and later maintenance are facilitated, and the water dripping from the filter cylinder 105 is prevented when the sludge is extruded again, and the accumulated water can only drip from the drainage cylinder 104 into the sewage collection area 12.

[0047] The other parts of the embodiment are the same as those of the above-described embodiments, and will not be described again.

[0050] By separating the drainage cylinder 104 and the sludge discharge cylinder 105 by the partition plate 102, the problem of the water filtered at the drainage cylinder 104 flowing to the sludge discharge cylinder 105 due to the uneven installation ground is effectively prevented, and the water flow into the sludge collection area 11 is avoided.

[0051] The other parts of the embodiment are the same as those of the above-described embodiments, and will not be described again.
