Detailed implementation mode

[0023] The technical solutions in the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] As Figure 1 And Figure 2 As shown in the figure, an embodiment of the present utility model provides a crushing and dust suppression device for barium sulfate powder production, which is installed at the feed inlet 1 and includes:

[0025] An air guide cover 2, an air outlet 9 is provided at the feed inlet 1, the air guide cover 2 is passed through the air outlet 9, and a fan 3 is provided on the air guide cover 2;

[0026] A filter screen 4, clamping blocks 10 are fixedly provided on both sides of the air guide cover 2, and the filter screen 4 is clamped between the two clamping blocks 10; and

[0027] A positioning block 11 is passed through the clamping block 10 and abuts against the side surface of the filter screen 4 for limiting the filter screen 4 between the two clamping blocks 10.

[0028] In the embodiment of the present utility model, before crushing, barium sulfate is conveyed to the position of the feed inlet 1 of the crusher through a conveyor belt, and at the same time, the fan 3 is started, so that the feed inlet 1, the air outlet 9, and the air guide cover 2 form a through air channel. The air flow enters the air guide cover 2 through the feed inlet 1 and the inside of the crusher, and finally is discharged through the fan 3. Under the action of the filter screen 4, the dust carried in the air flow can be adsorbed to prevent it from spreading through the feed inlet 1.

[0029] Secondly, in terms of the installation method of the filter screen 4, when installing it, since two clamping blocks 10 are mirror-symmetrically arranged on both sides of the air guide cover 2, the clamping blocks 10 are in an L-shaped structure, and the distance between the two clamping blocks 10 is adapted to the width of the filter screen 4, the filter screen 4 can be directly clamped between the two clamping blocks 10, and the end of the clamping block 10 has a limiting structure, so that after the filter screen 4 is clamped onto the clamping block 10, it will not slide out from the other end, completing the preliminary positioning of the filter screen 4. In order to ensure its stability, with the cooperation of the positioning block 11, the positioning block 11 is passed through the clamping block 10, so that the positioning block 11 can abut against the side surface of the filter screen 4, limiting the filter screen 4 between the two clamping blocks 10 and preventing it from moving, completing the final fixed installation of the filter screen 4. The method of limiting with the positioning block 11 enables the filter screen 4 to be quickly disassembled and replaced, greatly reducing the time required for maintenance. Moreover, the convenient disassembly and maintenance of the filter screen 4 can ensure the normal permeability of the filter screen 4, avoiding the blockage problem caused by long-term use, thereby maintaining a good dust removal effect.

[0030] Based on the above scheme, as Figure 2 And Figure 4As shown in the figure, the air guide cover 2 is provided with a groove 18. Two connecting rods 13 are slidably arranged in the groove 18. The two connecting rods 13 are respectively connected to the two positioning blocks 11. Tooth grooves 14 are formed in the two connecting rods 13. A gear 15 is rotatably arranged in the groove 18. The gear 15 is arranged between the two connecting rods 13 and meshes with the tooth grooves 14.

[0031] Under the action of the tooth grooves 14, accessories such as the connecting rods 13 and the gear 15 can be installed in an embedded manner, so that they do not protrude from the side surface of the air guide cover 2, enabling the air guide cover 2 to be completely installed at the position of the air outlet 9. And with the cooperation of the gear 15, the connecting rods 13 and the formed tooth grooves 14, since the two connecting rods 13 are both meshed with the gear 15 through the tooth grooves 14, when one of the connecting rods 13 is moved, the other connecting rod 13 can be driven to move synchronously, so that the two positioning blocks 11 can synchronously complete the limiting of the filter net 4 or release the limiting of it.

[0032] Secondly, a pull ring 17 corresponding to the connecting rod 13 is arranged on the inner wall of the groove 18. A tension spring 12 is arranged between the pull ring 17 and the connecting rod 13. Under the action of the tension spring 12, the initial state of the positioning block 11 is to abut against the side surface of the filter net 4. When the filter net 4 is between the two clamping blocks 10, the positioning block 11 is always subjected to the pulling force of the tension spring 12, ensuring the stability of the positioning block 11 and not easily moving. Before installing the filter net 4, by moving the connecting rod 13, the connecting rod 13 drives the tension spring 12 to deform. After the filter net 4 is clamped between the two clamping blocks 10, directly releasing the connecting rod 13 can make it reset under the action of the tension spring 12, simplifying the operation. The air guide cover 2 is rotatably provided with an adjusting knob 16. The adjusting knob 16 is fixedly connected to the gear 15. Under the action of the adjusting knob 16, the gear 15 can also be driven to rotate by rotating the adjusting knob 16, and the two connecting rods 13 can be adjusted synchronously through the gear 15.

[0033] Specifically, as Figure 3 shown, the air guide cover 2 is provided with a rectangular frame 8. When the air guide cover 2 passes through the air outlet 9, the rectangular frame 8 abuts against the top of the feed inlet 1. Through the action of the rectangular frame 8, it can play a role in carrying the air guide cover 2, facilitating the installation of the air guide cover 2 at the position of the air outlet 9. Moreover, the rectangular frame 8 increases the contact area between the air guide cover 2 and the feed inlet 1, ensuring the stability after installation.

[0034] Secondly, connecting brackets 7 are provided on both sides of the rectangular frame 8, telescopic rods 5 are provided on both sides of the feed inlet 1, the end portions of the connecting brackets 7 are bent outward to form bent portions 701, and the telescopic ends of the telescopic rods 5 are fixedly connected to the bent portions 701; in order to facilitate the disassembly, replacement and maintenance of the filter net 4, under the action of the telescopic rods 5, by starting the telescopic rods 5, the telescopic ends of the telescopic rods 5 can be extended, so as to lift the connecting brackets 7 on both sides of the rectangular frame 8, so that the rectangular frame 8 drives the air guide cover 2 to separate from the air outlet 9, exposing the entire air guide cover 2 structure for convenient disassembly operation; subsequently, by starting the telescopic rods 5 again, the telescopic ends of the telescopic rods 5 are contracted, and the air guide cover 2 can be driven to be installed in the air outlet 9 again to complete the installation. The above telescopic rods 5 can be one of an electric rod and a hydraulic rod.

[0035] Furthermore, limit blocks are provided on the inner side surfaces of the connecting brackets 7, limit grooves 6 are provided on both sides of the feed inlet 1, and the limit blocks are slidably clamped in the limit grooves 6; through the action of the limit blocks, the connecting brackets 7 can be clamped into the limit grooves 6 to limit the connecting brackets 7, ensuring that the connecting brackets 7 can only slide in the limit grooves 6, thereby ensuring the accuracy of the installation of the air guide cover 2 in the air outlet 9.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
