Description

Technical Field

[0001] This utility model relates to the technical field of sintered brick processing equipment, and in particular to a raw material screening device for sintered brick production. Background Technology

[0002] The production process of sintered bricks is a complex process involving the processing, molding, drying, and high-temperature firing of raw materials such as clay, shale, and coal gangue into bricks. Its core follows the path of "raw material processing → molding → drying → sintering → finished product." After the raw materials for brick making are extracted from the mine, they need to be crushed. The crushed particles are then separated and screened to select the appropriate particle size for brick production. The screened particles are then recycled. This process requires the use of sieves to screen the raw materials.

[0003] During the screening and separation process, existing screens often experience material blockage inside the screen holes. If this blockage is not cleaned, the number of holes available for screening will be reduced, thus affecting the overall screening and separation efficiency. Consequently, when screening the same amount of raw materials, a longer screening time will be required.

[0004] Therefore, it is necessary to provide a new raw material screening device for sintered brick production to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a raw material screening device for sintered brick production.

[0007] The cleaning assembly includes a support frame, on the outer wall of which multiple telescopic rods are fixedly installed. The ends of the multiple telescopic rods are provided with the same fixedly connected mounting plate. Multiple evenly distributed cleaning blocks are fixedly installed on the outer wall of the mounting plate. Springs are sleeved on the outside of the telescopic rods.

[0008] The outer wall of the screening roller is provided with a plurality of evenly distributed screen holes. The inner wall of the screen holes abuts against the outer wall of the cleaning block, and both the inner wall of the screen holes and the outer wall of the cleaning block are inclined structures.

[0009] Preferably, a baffle, a support plate, and a partition plate are fixedly connected below the top screening roller of the base plate. A support plate is rotatably connected to the top of the baffle. A hydraulic rod is rotatably connected between the support plate and the baffle via a shaft. The outer wall of the support plate is fixedly connected to the support frame.

[0010] Preferably, the outer wall of the support plate is provided with a drive motor fixedly connected to it, the output end of the drive motor is provided with a mounting plate fixedly connected to it, one side wall of the mounting plate is fixedly connected to the outer wall of the screening roller, and the other side wall of the mounting plate is provided with a fixing ring fixedly connected to it.

[0011] Preferably, two symmetrically distributed docking half-rings are inserted inside the fixed ring. The outer wall of the docking half-ring abuts against and is rotatably connected to the inner wall of the fixed ring. Multiple fixedly connected support rods are provided on the outer wall of the docking half-ring, and the support rods are fixedly connected to the support plate.

[0012] Preferably, a retaining ring is provided on the side of the outer wall of the screening roller away from the mounting plate.

[0014] Compared with related technologies, the raw material screening device for sintered brick production provided by this utility model has the following beneficial effects:

[0015] 1. By setting up a cleaning component, this utility model allows the cleaning blocks located in the cleaning component outside the screening drum to be inserted sequentially into the screen holes of the screening drum along the outer wall of the screening drum during use. This can push out and clean the particulate matter stuck in the screen holes during screening and separation, thereby reducing the impact of screen hole blockage on the screening and separation work during use. This ensures that the screen holes in the screening drum are always in the screening and separation work, reducing the impact of screen hole blockage on the screening efficiency of the screening drum.

[0016] 2. By placing the cleaning component outside the screening drum, this utility model allows for easy disassembly of the cleaning component by staff when it is damaged during subsequent use, thereby reducing the difficulty of maintenance and replacement for staff.

[0017] 3. By setting the separation device to a drum-type structure, the rotating screening drum can continuously rotate and screen the sintered brick raw materials inside it during use. Compared with the inclined flat plate screening device, the screening and separation time of the raw materials can be increased, thereby reducing the phenomenon of incomplete screening and separation of raw materials due to insufficient screening time. Therefore, the separation effect of this device can be improved. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 6 The present invention provides a raw material screening device for sintered brick production, which includes a base plate 1.

[0028] In the embodiments of this utility model, please refer to Figures 1 to 6A screening roller 2 for separating raw materials is mounted on a base plate 1, and cleaning components 3 are provided on both sides of the screening roller 2 at the top of the base plate 1. The cleaning components 3 include a support frame 31, on which multiple telescopic rods 32 are fixedly installed. The ends of the multiple telescopic rods 32 are provided with the same fixedly connected mounting plate 33. Multiple evenly distributed cleaning blocks 331 are fixedly installed on the outer wall of the mounting plate 33. Springs 321 are sleeved on the outside of the telescopic rods 32. Multiple evenly distributed screen holes 21 are opened on the outer wall of the screening roller 2. The inner wall of the screen holes 21 and the cleaning blocks 331 are connected to the screen roller 2. The outer walls of block 331 abut each other, and the inner wall of screen hole 21 and the outer wall of cleaning block 331 are both inclined structures. One end of spring 321 is fixedly connected to the outer wall of mounting plate 33, and the other end of spring 321 is fixedly connected to the outer wall of support frame 31. Below the screening roller 2 at the top of bottom plate 1, there is a fixedly connected baffle 11, support plate 12, and partition plate 14. The top of baffle 11 is provided with a rotatably connected support plate 4. A rotatably connected hydraulic rod 13 is mounted between support plate 4 and baffle 11 through a shaft, and the outer wall of support plate 4 is fixedly connected to support frame 31.

[0029] It should be noted that during use, when the rotating screening drum 2 screens the internal raw materials, the cleaning block 331 in the cleaning component 3 can be inserted into the screen hole 21 in the screening drum 2 along the outer wall of the screening drum 2. This can push out and clean the particulate matter stuck in the screen hole 21 during screening and separation. Therefore, it can reduce the impact of screen hole 21 blockage on the screening and separation efficiency during use, and thus enable the device to carry out screening operations stably.

[0030] By placing the cleaning component 3 outside the screening drum 2, when the cleaning component is damaged during subsequent use, the external device makes it easy for staff to disassemble the cleaning component 3, thereby reducing the difficulty of maintenance and replacement for staff in the later stages.

[0031] Furthermore, by setting up the hydraulic rod 13, after the raw materials are screened and separated, the extension of the hydraulic rod 13 can cause the connection between the support plate 4 and the baffle 11 to rotate as a node, thereby adjusting the external screening roller 2 to an inclined state so that the raw materials inside the screening roller 2 can be discharged outward.

[0032] By setting up the separator 14 and the baffle 11, the raw materials after screening can be classified so that the raw materials of different particles after classification can be processed independently in the later stage.

[0033] In this embodiment, a corrugated protective cover (not shown in the figure) can also be fitted over the outside of the spring 321 to protect the spring 321 and the telescopic rod 32. This can reduce the phenomenon of splashed particles scattering between the two during use and causing them to jam the telescopic movement of the two, thereby improving the stability of their movement.

[0034] In the embodiments of this utility model, please refer to Figures 1 to 6 A drive motor 62 is fixedly connected to the outer wall of the support plate 4. The output end of the drive motor 62 is fixedly connected to the mounting plate 6. One side wall of the mounting plate 6 is fixedly connected to the outer wall of the screening roller 2, and the other side wall of the mounting plate 6 is fixedly connected to the fixing ring 61. Two symmetrically distributed docking half-rings 42 are inserted inside the fixing ring 61. The outer wall of the docking half-ring 42 abuts against and is rotatably connected to the inner wall of the fixing ring 61. Multiple fixedly connected support rods 41 are provided on the outer wall of the docking half-ring 42, and the support rods 41 are fixedly connected to the support plate 4.

[0035] It should be noted that: through the abutment between the fixed ring 61 and the docking half ring 42, when the drive motor 62 drives the screening drum 2 to rotate through the mounting plate 6, the docking half ring 42 can support the outer side of the mounting plate 6 when it rotates through the support rod 41, so that the mounting plate 6 can stably drive the screening drum 2 to rotate.

[0036] In the embodiments of this utility model, please refer to Figures 1 to 6 A retaining ring 5 is provided on the side of the outer wall of the screening roller 2 away from the mounting plate 6. The retaining ring 5 abuts against the screening roller 2 and is rotatably connected. Multiple evenly distributed electric push rods 51 are fixedly installed on the outer wall of the retaining ring 5, and the ends of the electric push rods 51 away from the retaining ring 5 are fixedly connected to the outer wall of the support plate 4.

[0037] It should be noted that: by setting the retaining ring 5, when in use, the retaining ring 5, which abuts against the outer wall of the screening drum 2, can block the outer wall of the screening drum 2 after the raw material is added into the screening drum 2. This can reduce the phenomenon of raw material flowing out from the side wall of the screening drum 2, thus enabling the screening drum 2 to smoothly screen and separate the raw material.

[0038] Since the retaining ring 5 and the screening drum 2 are in contact, after the raw material is screened and separated, the retaining ring 5 can be moved away from the screening drum 2 by the operation of the electric push rod 51, so that the retaining ring 5 and the screening drum 2 are separated, thereby removing the obstruction to the side wall of the screening drum 2, so that the screened raw material can be discharged from the screening drum 2.

[0039] The working principle of the raw material screening device for sintered brick production provided by this utility model is as follows:

[0040] When using this device, the operator can add the sintered brick raw material to be separated into the screening drum 2. After the raw material is added, the drive motor 62 can be controlled to work. The working drive motor 62 can drive the screening drum 2 to rotate through the mounting plate 6. At this time, the rotating screening drum 2 can drive the raw material inside to rotate.

[0041] During this process, fine particles in the raw material can fall out through the screen holes 21 in the screening drum 2, thereby achieving the separation of the raw material. In this process, since the inner wall of the screen hole 21 and the outer wall of the cleaning block 331 are inclined structures, when the two inclined surfaces abut, the squeezing force can push the cleaning block 331 out of the screen hole 21. As the screening drum 2 continues to rotate, the cleaning block 331 can be inserted into the subsequent screen hole 21 under the action of the spring 321, thereby achieving the removal and cleaning of the material stuck inside the screen hole 21. Therefore, the impact of screen hole 21 blockage on screening and separation during use can be reduced, and the screen holes 21 in the screening drum 2 can always be in screening and separation operation, reducing the impact of screen hole 21 blockage on the screening efficiency of the screening drum 2.

[0042] After the screening and separation of the raw materials inside the screening drum 2 is completed, the hydraulic rod 13 can be extended. The extended hydraulic rod 13 can drive the support plate 4 connected to it. The rotating support plate 4 can rotate with the part connected to the baffle 11 as the node. The tilted support plate 4 will drive the external screening drum 2 to tilt synchronously. When the screening drum 2 is tilted, the electric push rod 51 can be controlled to work. The extended electric push rod 51 will drive the end retaining ring 5 to move away from the screening drum 2, so that the retaining ring 5 can be separated from the screening drum 2, and the obstruction of the side of the screening drum 2 away from the support plate 4 can be released. At this time, the raw materials inside the screening drum 2 can flow out smoothly from the tilted screening drum 2.

[0043] After the material is fed, the electric push rod 51 and hydraulic rod 13 can be controlled to reset so that the screening and separation of raw materials can continue.

[0044] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0045] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
