Description

Technical Field

[0001] The utility model belongs to the technical field of pretreatment of raw materials for ceramsite production, and in particular relates to a sludge raw material pretreatment device for ceramsite production. Background Art

[0002] The raw materials for the production of ceramsite mainly include base materials and auxiliary materials. The base materials of ceramsite come from a wide range of sources. In recent years, they have gradually evolved from early mineral resources such as clay and shale to industrial solid waste. Among them, industrial solid waste used in the production of ceramsite can be divided into coal-based solid waste (fly ash, coal gangue, etc.), industrial waste slag (steel slag, slag, blast furnace slag, non-ferrous metal slag, coal slag, etc.), industrial tailings (various tailings produced by mineral processing) and sludge, etc. according to their sources.

[0003] A crusher is needed to crush the dewatered sludge. The existing crushers mainly use crushing rollers to crush the soil entering the crushing box of the crusher. The crushed soil is discharged through the discharge port. However, it is difficult to crush it completely at one time. The discharged soil contains large sludge particles. The staff is required to pour the discharged sludge back into the crusher for secondary crushing. The operation is repeated until it is completely crushed. The staff repeatedly collects the powder and pours it into the crusher, which not only slows down the crushing process, but also consumes manpower and is more troublesome. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a sludge raw material pretreatment device for ceramsite production.

[0005] To achieve the above-mentioned purpose, the utility model proposes a sludge raw material pretreatment device for expanded clay production, comprising a bracket, the upper surface of the bracket is fixedly connected to a circular shell, the upper and lower surfaces of the circular shell are both provided with square through grooves, the inside of the circular shell is rotatably connected to a circular plate, the two circular plates are fixedly connected to the square shell, the upper and lower surfaces of the square shell are matched with the inner wall of the circular shell, the upper and lower sides of the square shell are both provided with second square through grooves, the second square through grooves are larger than the first square through grooves, the inner wall of the square shell is rotatably connected to an arc filter plate at the position of the two second square through grooves, a torsion spring is provided at the connection between the filter plate and the square shell, the inside of the square shell is rotatably connected to two rolling rollers, and the two rolling rollers are horizontally arranged in the middle position of the square shell.

[0006] In one example, the main shaft of the rolling roller passes through the square shell and the circular plate, and the main shafts of the two rolling rollers are fixedly connected to gears, and the two gears are meshed. One side of one of the circular plates is fixedly connected to a fixing frame, and a servo motor is installed on the fixing frame. The main shaft of the servo motor is fixed at the center position of one of the gears.

[0007] In one example, the inner wall of the square shell is located on both sides of the rolling roller and is fixedly connected to the arc plates, and the four arc plates are against the outer side of the rolling roller.

[0008] In one example, one side of the circular shell is fixedly connected to a protective shell, a driving motor is installed in the protective shell, the main shaft of the driving motor passes through the circular shell, the main shaft of the driving motor is fixedly connected to another circular plate, and the connection position is located at the center of the circular plate.

[0009] In one example, a feeding pipe is fixedly connected to the outer side of the circular shell near the upper first square through groove.

[0010] In one example, the inner wall of the feeding tube is slidably connected to a sliding tube, and the lower end of the sliding tube is tapered.

[0011] In one example, four vertical rods are fixedly connected to the upper surface of the feeding tube, and the vertical rods all penetrate the upper wall of the sliding tube. A spring is fixedly connected between the sliding tube and the feeding tube.

[0012] The sludge raw material pretreatment device for ceramsite production proposed by the utility model can bring the following beneficial effects:

[0013] First, by setting a square shell, the dewatered sludge raw material is poured into the square shell through the gap. When the sludge passes between two rolling rollers, the rolling roller rolls the sludge, squeezes and breaks the sludge blocks to form powder. The powder passes through the filter plate below and leaves the circular shell, while the larger sludge particles or sludge particles agglomerated due to rolling remain on the filter plate below. At this time, the square shell rotates and exchanges up and down, and the larger sludge particles go to the top, causing the larger sludge to fall again and pass through the rolling rollers for rolling and crushing again. This exchange is repeated many times, and the rolling is repeated until all the sludge in the square shell is crushed to a state that meets the requirements, thereby improving the rolling and crushing effect of the sludge and avoiding residue.

[0014] Secondly, by setting a sliding tube, when adding materials, the sliding tube is pressed down, and the sliding tube pushes the filter plate to open the square shell, and the material enters the square shell through the sliding tube. After adding materials, the sliding tube is released, and under the push of the spring, the sliding tube leaves the square shell and the filter plate is reset. The opening above the feeding tube is far away from the square shell, which can reduce the dust flying out during rolling, and there is no need to press down the filter plate by hand, which is safer.

[0022] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0023] like Figure 1 to Figure 4As shown, an embodiment of the utility model proposes a sludge raw material pretreatment device for ceramsite production, including a bracket 1, the upper surface of the bracket 1 is fixedly connected to a circular shell 2, the upper and lower surfaces of the circular shell 2 are both provided with square through grooves, the inside of the circular shell 2 is rotatably connected to a circular plate 3, the two circular plates 3 are fixedly connected to a square shell 4, the upper and lower surfaces of the square shell 4 match the inner wall of the circular shell 2, the upper and lower sides of the square shell 4 are both provided with a second square through groove, the second square through groove is larger than the first square through groove, the inner wall of the square shell 4 is located at the position of the two second square through grooves and is rotatably connected to an arc filter plate 5, a torsion spring is provided at the connection between the filter plate 5 and the square shell 4, the inside of the square shell 4 is rotatably connected to two rolling rollers 6, the two rolling rollers 6 are horizontally arranged in the middle position of the square shell 4, when adding materials, the second square through groove is aligned with the first square through groove respectively, and the first square through groove at the top of the circular shell 2 is used to filter the material. The filter plate 5 in the square shell 4 is pressed down to rotate the filter plate 5 inward, and a gap appears between the two filter plates 5. The dewatered sludge raw material is poured into the square shell 4 through the gap. The filter plate 5 is restored, and the sludge falls. When it passes between the two rolling rollers 6, the rolling rollers 6 are in a rotating state at this time, and the sludge is rolled to crush the sludge blocks to form powder. The powder passes through the filter plate 5 below, the second square through groove below and the first square through groove, and leaves the circular shell 2, while the larger sludge particles or the sludge particles agglomerated due to rolling remain on the filter plate 5 below. At this time, the square shell 4 rotates, exchanges up and down, and the larger particles of sludge turn to the top, causing the larger sludge to fall again, pass between the rolling rollers 6 again, and be crushed again. This exchange is repeated for many times, and the rolling is repeated until all the sludge in the square shell 4 is crushed to a state that meets the requirements, thereby improving the crushing effect of the sludge and avoiding residue.

[0024] like Figure 3 As shown, the main shaft of the rolling roller 6 passes through the square shell 4 and the circular plate 3, and the main shafts of the two rolling rollers 6 are fixedly connected to the gear 7, and the two gears 7 are meshed. One side of one of the circular plates 3 is fixedly connected to the fixing frame 8, and a servo motor 9 is installed on the fixing frame 8. The main shaft of the servo motor 9 is fixed at the center position of one of the gears 7. The rolling roller 6 is driven by the servo motor 9, and the servo motor 9 drives the two rolling rollers 6 to rotate in opposite directions through the gear 7. At the same time, the rotation direction of the two rolling rollers 6 is the same as the direction of sludge falling, which helps to speed up the speed of the sludge passing through the two rolling rollers 6. When the square shell 4 rotates, the upper and lower parts are exchanged, and the larger particles of sludge move to the top, and the servo motor 9 drives the rolling roller 6 in the opposite direction, so that the rotation direction of the two rolling rollers 6 is always the same as the direction of sludge falling.

[0025] like Figure 2 and Figure 4As shown, the inner wall of the square shell 4 is located on both sides of the rolling roller 6 and is fixedly connected to the arc plate 10. The four arc plates 10 are all against the outside of the rolling roller 6. The arc plate 10 covers the two rolling rollers 6 and has a guiding function, so that the sludge gathers between the two rolling rollers 6, and promotes the sludge to contact the rolling roller 6 for rolling. The arc plate 10 is against the outside of the rolling roller 6, and the sludge attached to the rolling roller 6 due to rolling can be shoveled off.

[0026] like Figure 1 As shown, one side of the circular shell 2 is fixedly connected to the protective shell 11, and a driving motor is installed in the protective shell 11. The main shaft of the driving motor passes through the circular shell 2. The main shaft of the driving motor is fixedly connected to another circular plate 3, and the connection position is located at the center of the circular plate 3. The driving motor is used to drive the circular plate 3 and the square shell 4 to rotate simultaneously to exchange the upper and lower parts.

[0027] like Figure 1 As shown, a feeding pipe 12 is fixedly connected to the outer side of the circular shell 2 near the first square through groove at the top, and the sludge raw material enters the square shell 4 through the feeding pipe 12. The upper opening of the feeding pipe 12 is far away from the square shell 4, which can reduce the dust floating out during rolling.

[0028] like Figure 1 and Figure 2 As shown, the inner wall of the feeding tube 12 is slidably connected to the sliding tube 13, and the lower end of the sliding tube 13 is conical. When feeding, the sliding tube 13 is pressed down, and the sliding tube 13 pushes the filter plate 5 to open the square shell 4. The material enters the interior of the square shell 4 through the sliding tube 13. Feeding is more convenient and there is no need to press down the filter plate 5 by hand, which is safer.

[0029] like Figure 1 As shown, four vertical rods 14 are fixedly connected to the upper surface of the feeding tube 12, and the vertical rods 14 all penetrate the upper wall of the sliding tube 13. A spring 15 is fixedly connected between the sliding tube 13 and the feeding tube 12. After feeding, the sliding tube 13 is released, and under the push of the spring 15, the sliding tube 13 leaves the square shell 4 and the filter plate 5 is reset, which is more convenient to use.

[0030] Working principle: when feeding, press down the sliding tube 13, the sliding tube 13 pushes the filter plate 5 to open the square shell 4, and the material enters the inside of the square shell 4 through the sliding tube 13. After feeding, release the sliding tube 13. Under the push of the spring 15, the sliding tube 13 leaves the square shell 4 and the filter plate 5 is reset. The servo motor 9 drives the two rolling rollers 6 to rotate in opposite directions through the gear 7. At the same time, the rotation direction of the two rolling rollers 6 is the same as the direction of sludge falling. When the sludge falls and passes between the two rolling rollers 6, the rolling rollers 6 are in a rotating state, rolling the sludge, squeezing and crushing the sludge blocks to form powder. The powder passes through the filter plate 5 below, the second square through groove below and the first square through groove, and leaves the circular shell 2. The larger sludge particles or the sludge particles agglomerated by rolling stay on the filter plate 5 below. The driving motor drives the circular plate 3 and the square shell 4 to rotate at the same time, so that the upper and lower parts are exchanged, and the larger particles of sludge turn to the upper side, so that the larger sludge falls again, passes between the rolling rollers 6 again, and is crushed again. This exchange is repeated for many times and the rolling is repeated.
