[0002] With the rapid pace of urbanization and booming industrial development, the amount of sludge generated is increasing dramatically. Urban wastewater treatment plants process large quantities of domestic sewage daily, producing significant amounts of sludge in the process. Similarly, industrial production sectors, such as chemical, printing and dyeing, and papermaking industries, also generate industrial sludge rich in various pollutants.

[0003] Expanded clay aggregate is a lightweight, porous building material with many excellent properties such as light weight, thermal insulation, fire resistance, and earthquake resistance. It is widely used in construction, horticulture, water treatment, and other fields. Preparing sludge into expanded clay aggregate can not only reduce, render harmless, and recycle sludge, thus reducing its harm to the environment, but also produce economically valuable expanded clay aggregate products, realizing the recycling of waste and achieving good environmental and economic benefits.

[0004] The process of preparing ceramsite from sludge usually includes key steps such as raw material pretreatment, batching and mixing, granulation, and calcination. The main purpose of feed pretreatment is to pre-condition and modify the sludge, reduce its moisture content, and improve its physical and chemical properties to make it more suitable for subsequent batching, mixing, and granulation operations.

[0005] In the traditional pretreatment process of sludge to ceramsite feed, the main method is to manually operate simple pressing equipment, such as manual screw presses, to squeeze the sludge to remove some of the moisture. However, during the pressing process, the operator needs to forcefully turn the handle of the pressing equipment or operate other mechanical parts, which is time-consuming, labor-intensive, and inefficient.

[0006] Therefore, in order to address the above problems, the applicant needs to design a feed pretreatment device for sludge to prepare ceramsite. Utility Model Content

A telescopic rod is disposed on the fixing plate, and a support plate is disposed at the end of the telescopic rod away from the fixing plate.

[0010] The control component is located inside the moving block and is used to drive the moving block to move linearly.

[0011] Furthermore, the control component includes a threaded rod that is threadedly connected to the moving block, and a linkage wheel is fixedly provided at one end of the threaded rod. A belt is coupled to the linkage wheel, and a rotating wheel is coupled to the belt. A servo motor is provided on the rotating wheel, and the servo motor is fixedly connected to the support plate.

[0012] Furthermore, a bearing seat is provided at the end of the threaded rod away from the linkage wheel, and a fixing column is fixedly provided on the bearing seat, and the fixing column is fixedly connected to the support plate.

[0013] Furthermore, the bearing housing includes a bearing outer ring fixedly connected to a fixed column, and a ball is provided on the inner side of the bearing outer ring. An inner bearing ring is provided on the inner side of the ball, and the bearing inner ring is connected to a threaded rod.

[0014] Furthermore, the bottom surface of the placement seat is provided with a base, and the base is provided with water-permeable holes.

[0025] like Figures 1-4As shown, the present invention discloses a feeding pretreatment device for preparing ceramsite from sludge, comprising a placement seat 11, wherein a filter screen 12 is provided inside the placement seat 11, and further comprising: a pressing plate 13 disposed above the placement seat 11, wherein an extrusion mechanism 2 is disposed above the pressing plate 13 for moving the pressing plate 13, the extrusion mechanism 2 comprising a lifting plate 20 fixedly connected to the pressing plate 13, wherein a lower rotating rod 21 is rotatably disposed on the lifting plate 20, wherein a moving block 22 is rotatably disposed at the end of the lower rotating rod 21 away from the lifting plate 20, wherein an upper rotating rod 23 is rotatably disposed on the moving block 22, wherein a connecting block 24 is rotatably disposed at the end of the upper rotating rod 23 away from the moving block 22, wherein a fixing plate 240 is fixedly disposed on the connecting block 24, wherein a telescopic rod 241 is disposed on the fixing plate 240, wherein a support plate 25 is disposed at the end of the telescopic rod 241 away from the fixing plate 240; and a control component 27 disposed inside the moving block 22, wherein the control component 27 is used to drive the moving block 22 to move linearly.

[0026] The control component 27 includes a threaded rod 270 that is threadedly connected to the movable block 22. One end of the threaded rod 270 is fixedly provided with a linkage wheel 271. A belt 272 is coupled to the linkage wheel 271, and a rotating wheel 273 is coupled to the belt 272. A servo motor 274 is provided on the rotating wheel 273, and the servo motor 274 is fixedly connected to the support plate 25. The servo motor 274 drives the belt 272 to drive the linkage wheel 271 and the threaded rod 270, thereby achieving the stability and controllability of power transmission. The threaded connection design between the threaded rod 270 and the movable block 22 accurately converts the rotational motion into linear displacement.

[0027] A bearing seat 275 is provided at the end of the threaded rod 270 away from the linkage wheel 271. A fixing column 276 is fixedly installed on the bearing seat 275 and is fixedly connected to the support plate 25. The cooperation between the bearing seat 275 and the fixing column 276 provides reliable radial support for the threaded rod 270, effectively preventing the threaded rod 270 from deflecting or vibrating under load.

[0030] The bottom surface of the base 1 is provided with a collection pool 14, and a drainage pipe 15 is connected to the collection pool 14. The connection design between the collection pool 14 and the drainage pipe 15 realizes the centralized recycling and directional discharge of the squeezed wastewater.

[0031] A support rod 26 is fixedly installed on the collection pool 14, and the end of the support rod 26 away from the collection pool 14 is fixedly connected to the bottom surface of the support plate 25.

[0032] Working principle: When using the sludge pretreatment device for preparing ceramsite, the servo motor 274 drives the rotating wheel 273 to rotate, and the belt 272 drives the linkage wheel 271 and the threaded rod 270 to rotate synchronously. The threaded rod 270 is threadedly engaged with the moving block 22 of the control component 27, converting the rotational motion into the horizontal linear displacement of the moving block 22. The moving block 22 pushes the lifting plate 20 to move vertically through the hinged lower rotating rod 21 and upper rotating rod 23, which in turn drives the pressing plate 13 to apply downward pressure to the sludge in the placement seat 11. After the sludge is pressed, the water seeps out through the filter screen 12 and the water-permeable holes 10 of the base 1 to the collection tank 14, and is finally discharged through the drainage pipe 15. The dewatered sludge is left in the placement seat 11, completing the pretreatment. The operation is convenient and the working efficiency is high.
