Description

Technical Field

[0001] This utility model relates to the technical field of waste recycling devices, specifically a separation device for recycling solid and liquid waste from cement kilns. Background Technology

[0002] During the production process of cement kilns, a large amount of solid-liquid mixed waste containing cement clinker residue, fine dust, alkaline substances, and soluble harmful substances is generated. If such waste is discharged directly, it will not only cause soil and water pollution, but also waste the recyclable solid particles and water resources. Therefore, solid-liquid separation is the core link of cement kiln environmental protection and resource recycling. At present, cement kiln solid-liquid waste separation mainly adopts technologies such as sedimentation, centrifugation, or filtration.

[0003] The cement kiln solid-liquid waste recycling device with reduction treatment according to announcement number CN213792219U includes a main housing, a baffle and a fan. A motor is fixed on the main housing, and a drive gear is fixed at the end of the motor output shaft. The drive gear and the driven gear are connected to each other, and the driven gear bearing is fixed on the main housing.

[0004] The aforementioned device increases the separation speed through centrifugal force, but the filter screen is fixed inside the separation chamber. Cleaning requires disassembling the separation chamber and connecting rod, which is cumbersome and time-consuming. In addition, the filter screen lacks sealing optimization, allowing fine particles to easily leak through the gap between the filter screen and the separation chamber, resulting in insufficient separation accuracy. Subsequent liquids require additional secondary filtration, increasing processing costs. Utility Model Content

[0005] The purpose of this utility model is to provide a separation device for recycling solid and liquid waste from cement kilns, so as to solve the technical problems of insufficient separation accuracy, high processing cost and complicated operation of existing solid-liquid separation devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A separation device for recycling solid and liquid waste from a cement kiln includes a support block and a first filter screen.

[0012] As a preferred embodiment of this utility model, the collecting cylinder is provided with a feeding hole below the filter grid, and a feeding pipe is fixedly connected to the inner wall of the feeding hole.

[0013] As a preferred embodiment of this utility model, a box door is hinged to one side of the outer wall of the collection cylinder, and the box door is provided with an observation window.

[0014] Compared with the prior art, the beneficial effects of the separation device for solid-liquid waste recycling in cement kilns of this utility model are as follows: the device drives the filter screen and filter grid to rise and fall synchronously through the slider, so as to realize the graded filtration of coarse impurities first by the grid and fine slag second by the filter screen. At the same time, when the slider moves, it drives the stirring blade to stir the waste liquid, thereby increasing the mixing effect. The filter screen and filter grid are detachably connected to the slider through the pin, and can be removed for cleaning or replacement simply by pulling out the pin. The slag cleaning time is shortened, avoiding long-term downtime. At the same time, the rubber ring ensures the filter sealing and prevents small particles from flowing out from the gaps in the filter screen. Attached Figure Description

[0025] See Figure 1-5As shown in the figure, an embodiment of the present invention provides a separation device for recycling solid and liquid waste from a cement kiln, comprising a support block 1 and a first filter screen 2. A sliding hole is provided on one side of the outer wall of the support block 1, and a slider 3 is slidably connected to the inner wall of the sliding hole. A collection cylinder 4 is fixedly connected to one end of the outer wall of the support block 1.

[0026] A fixing groove is provided through the upper end of the collecting cylinder 4. A filter grid 5 is snapped into the inner wall of the fixing groove. A first filter screen 2 is provided inside the collecting cylinder 4. One end of the slider 3 extends into the collecting cylinder 4 and is fixedly connected to the filter grid 5 and the first filter screen 2. A stirring blade 6 is rotatably connected below the first filter screen 2. One end of the first filter screen 2 and the filter grid 5 are provided with a protrusion that extends through into the slider 3. A pin hole is provided through the outer wall of one end of the slider 3. The pin hole extends through into the first filter screen 2 and the filter grid 5 and is inserted with a pin 7. One end of the pin 7 is provided with an anti-slip handle. A rubber ring 9 is fixedly connected to the outer wall of the first filter screen 2. The rubber ring 9 abuts against the inner wall of the collecting cylinder 4. An inclined guide surface is provided on the semi-circular inner wall of the lower end of the collecting cylinder 4.

[0027] A hydraulic rod 10 is fixedly connected to one side of the outer wall of the support block 1. The output end of the hydraulic rod 10 is fixedly connected to the slider 3, which facilitates the use of the hydraulic rod 10 to push the slider 3 up and down. A drain hole is provided on the inner wall of one end of the collecting cylinder 4 and a drain pipe 11 is fixedly connected to it. The drain pipe 11 extends to the outside of the collecting cylinder 4 and is equipped with a valve. A second filter screen 8 is provided at the end of the drain pipe 11 near the collecting cylinder 4, which facilitates the use of the drain pipe 11 to discharge the waste liquid in the collecting cylinder 4. The lower end of the collecting cylinder 4 is semi-circular and has a drain opening. The inner wall of the discharge hole is fixedly connected to a discharge pipe 12, which extends to the outside of the collection cylinder 4 and is equipped with a valve to facilitate the discharge of flocculated material. The collection cylinder 4 is located below the filter grid 5 and has a feeding hole.

The door 14 is equipped with an observation window to facilitate closing the door 14 to prevent impurities from entering the collection cylinder 4.

[0028] In use, the hydraulic rod 10 is connected to an external drive source via a controller. Waste feeding and preliminary filtration involve slowly pouring cement kiln solid-liquid waste into the collection cylinder 4 through the upper opening. The waste first passes through the filter grid 5, which traps clinker residue. The remaining waste liquid containing fine particles passes through the filter grid 5 and enters above the first filter screen 2. Fine dust in the waste liquid is trapped by the first filter screen 2. The pre-filtered waste liquid flows into the lower part of the collection cylinder 4, where flocculant is added through the feeding pipe 13. The hydraulic rod 10 is activated, causing the slider 3 to move upwards. The slider 3 moves the filter grid 5 and the first filter screen 2 out of the collection cylinder 4. As the first filter screen 2 rises, it moves the stirring blade 6, which, along with the first filter screen 2, stirs the solution in the collection cylinder 4. After removal, the anti-slip handle is used to pull the pin 7 out of the pin hole, removing the first filter screen 2 and the filter grid 5 for solid waste recycling.

[0029] After recycling, insert the first filter screen 2 and the filter grid 5 into the slider 3, and reinsert the pin 7 into the pin hole to limit and fix the first filter screen 2 and the filter grid 5. Close the box door 14. You can observe whether the waste has completed flocculation through the observation window. After flocculation is completed, open the drain pipe 11 to discharge the clear liquid on the upper layer of the flocculated liquid. Place the flocculated material on the second filter screen 8 to be discharged from the drain pipe 11. After the clear liquid is discharged, open the discharge pipe 12. The deposited flocculated material is discharged from the discharge pipe 12 under the guidance of the inclined guide surface.
