Description

Technical Field

[0001] The utility model relates to the field of cement production equipment, in particular to a cement dust cleaning system. Background Art

[0002] The material conveyor used in the cement production process is used to transport various raw materials. Since most of these materials are in dry powder form and have adhesive properties, after the material conveyor feeds the materials, the materials will not completely detach from the surface of the conveyor belt, and a small amount of materials will adhere to it. When the conveyor belt rotates back, the attached materials will also adhere to the rollers below the conveyor belt. Moreover, as the conveyor belt operates for a long time, more and more materials will be attached to it. If it is not cleaned in time, it will affect the normal operation of the rollers. In addition, the materials adhered to the rollers will cause the belt surface of the conveyor belt to wear and age, affecting its service life. Summary of the Invention

[0057] According to a cement dust cleaning system 100 of the present invention, Figure 1As shown, it is applied to a cement conveyor 200, and the cement conveyor 200 includes: a box 220 and a conveyor belt 210 arranged in the box 220. The box 220 is also provided with a dust collection device for absorbing dust during the conveying process of the cement conveyor 200. The cement dust cleaning system 100 includes:

[0058] Blower 110;

[0059] a pressure pump 120 , connected to the blower 110 , configured to pressurize external air to form pressurized gas;

[0060] The nozzle 130 is connected to the pressure pump 120 through the nozzle 140 , and the nozzle 130 is installed on one side of the conveyor belt 210 and is configured to blow pressurized gas toward the surface of the conveyor belt 210 .

[0061] The working process of the cement dust cleaning system 100 is as follows: the blower 110 blows external air into the cleaning system 100, and the external air is pressurized by the pressure pump 120 to form pressurized gas. The pressurized gas flows through the nozzle 140 to the nozzle 130, and finally is sprayed onto the surface of the conveyor belt 210 by the nozzle 130, and then the cement dust on the surface of the conveyor belt 210 is blown off. The blown-off cement dust is negatively adsorbed by the dust collection equipment in the box 220, and the blown-off cement dust is adsorbed away; the cement dust cleaning system 100 can clean the material on the conveyor belt 210 in time, avoid the material adhering to the roller causing the belt surface of the conveyor belt 210 to be worn and aged, and extend the service life of the conveyor belt 210.

[0062] In one example of the present invention, it further includes: an adjustment device 150,

[0063] The adjusting device 150 is disposed near the conveyor belt 210 , the nozzle 130 is connected to the adjusting device 150 , and the adjusting device 150 is configured to adjust the angle of the nozzle 130 .

[0064] By providing the adjustment device 150 in the box body 220, the angle of the nozzle 130 can be flexibly adjusted, thereby adjusting the spraying angle of the nozzle 130 to match the surface of the conveyor belt 210, thereby obtaining the best cleaning angle.

[0065] In one example of the present invention, Figure 2 As shown, the regulating device 150 includes:

[0066] The sleeve 151 is pivotally connected to the box 220 , and the nozzle 130 is fixedly connected to the sleeve 151 on the side close to the conveyor belt 210 ;

[0067] a driving mechanism 152 connected to the sleeve 151 and configured to drive the sleeve 151 to rotate synchronously therewith;

[0068] Specifically, when it is necessary to adjust the angle of the nozzle 130, since the nozzle 130 is connected to the sleeve 151, the driving mechanism 152 drives the sleeve 151 to rotate around its own axis, thereby adjusting the rotation angle of the sleeve 151, and then achieving the optimal cleaning angle of the nozzle 130; since the nozzle 130 is arranged in the box 220 and is arranged close to the conveyor belt 210, the angle adjustment of the nozzle 130 can be easily achieved by setting an adjustment mechanism, thereby improving the safety of the angle adjustment.

[0069] In one example of the present invention,

[0070] The driving mechanism 152 includes:

[0071] Drive motor 1521;

[0072] A driving gear 1522 is fixedly connected to the output shaft of the driving motor 1521;

[0073] The driven gear 1523 is fixedly sleeved on the outer side of the sleeve 151 and meshes with the driving gear 1522; wherein the number of teeth of the driven gear 1523 is greater than the number of teeth of the driving gear 1522;

[0074] When the angle of the nozzle 130 needs to be adjusted, since the nozzle 130 is connected to the sleeve 151, the driving motor 1521 drives the driving gear 1522 to rotate, and then the driving gear 1522 drives the driven gear 1523 engaged with it to rotate, and then drives the sleeve 151 fixedly connected to the driven gear 1523 to rotate, so that the sleeve 151 rotates around its own axis, thereby adjusting the rotation angle of the sleeve 151, and then achieving the optimal cleaning angle of the nozzle 130; since the nozzle 130 is arranged in the box 220 and is arranged close to the conveyor belt 210, the angle adjustment of the nozzle 130 can be easily achieved by setting an adjustment mechanism, thereby improving the safety of the angle adjustment.

[0075] In one example of the present invention, the driving motor 1521 is a servo motor; the servo motor has very high motion accuracy and control accuracy, can achieve very precise positioning and motion control, and facilitates the angle adjustment of the sleeve 151.

[0076] In one example of the present invention, the adjustment device 150 further includes:

[0077] The bearings 160 are respectively provided on both sides of the sleeve 151 , with the inner ring of the bearings 160 fixedly connected to the sleeve 151 and the outer ring of the bearings 160 fixedly connected to the housing 220 ;

[0078] Specifically, bearings 160 are respectively provided on both sides of the sleeve 151. By providing the bearings 160, on the one hand, the sleeve 151 can be supported, and on the other hand, the sleeve 151 can be rotatably connected in the box body 220. The adjusting device 150 also includes: a support platform 170, which is provided on the lower end side of the bearing 160 and is fixedly connected to the outer ring of the bearing 160 for supporting the sleeve 151.

[0079] In one example of the present invention, the nozzle 140 includes a main tube portion 141 and an auxiliary tube portion 142 connected to the main tube portion 141, wherein the main tube portion 141 is disposed in the sleeve 151, and the auxiliary tube portion 142 is connected to the nozzle 130, and the auxiliary tube portion 142 is a flexible tube;

[0080] That is to say, when the driving mechanism 152 drives the sleeve 151 to rotate, the nozzle 130 is fixed on the sleeve 151, so it rotates along with the rotation of the sleeve 151. Since the auxiliary tube portion 142 is a flexible tube, the main tube portion 141 remains stationary, and the auxiliary tube portion 142 rotates along with the rotation of the nozzle 130.

[0081] For example, mounting holes are opened on the outer peripheral wall of the sleeve 151, and the mounting holes are arranged at intervals along the length direction of the sleeve 151. The nozzle 130 can be connected to the sleeve 151 by threaded connection.

[0082] In short, by providing the sleeve 151 on the outside of the nozzle 140 , the angle of the nozzle 140 can be easily adjusted.

[0083] In one example of the present invention, at the distal end of the auxiliary tube portion 142 (connected to the nozzle 130), one or more elongated thinning portions are provided on the outer circumferential surface or the inner circumferential surface of its outer tube layer, and the extension direction of the one or more elongated thinning portions is at an angle to the longitudinal direction of the auxiliary tube portion 142, thereby improving the end flexibility of the auxiliary tube portion 142.

[0084] The extending direction of the thinned portion is not parallel to the longitudinal direction of the auxiliary tube portion 142, thereby improving the flexibility of the catheter end portion while maintaining the strength of the auxiliary tube portion 142. It should be noted that one or more elongated thinned portions may also be provided on the inner circumferential surface of the outer tube layer, or on both the outer circumferential surface and the inner circumferential surface.

[0085] In one example of the present invention, Figure 3 As shown, the one or more elongated thinned portions are one or more spiral grooves 1421 located on the outer circumferential surface or the inner circumferential surface of the auxiliary tube portion 142 .

[0086] Wherein, at the distal end of the auxiliary tube portion 142, a plurality of annular grooves 1422 are provided on the outer peripheral surface of the outer tube layer thereof. Preferably, the plurality of annular grooves 1422 are transverse to the longitudinal direction of the auxiliary tube portion 142.

[0087] In one example of the present invention, Figure 4 As shown, the one or more elongated thinned portions are a plurality of annular grooves 1422 located on the outer circumferential surface or the inner circumferential surface of the auxiliary tube portion 142 .

[0088] At the distal end of the auxiliary tube portion 142, a plurality of spiral grooves 1421 are provided on the outer circumferential surface of the outer tube layer thereof. These spiral grooves 1421 may form an angle between 0 and 90 degrees with respect to the longitudinal direction of the auxiliary tube portion 142, such as, but not limited to, 10, 20, 30, or 40 degrees.

[0089] Furthermore, although not shown, the plurality of annular grooves 1422 or the plurality of spiral grooves 1421 may also be on the inner circumferential surface of the outer tube layer, or on both the outer circumferential surface and the inner circumferential surface.

[0090] The above technical solution solves the problem of the auxiliary tube 142 being stiff and difficult to turn at its distal end. By providing several thinned portions in specific directions at the distal end of the auxiliary tube 142, on the outer or inner circumferential surface of the outer tube layer, the head flexibility of the auxiliary tube 142 can be reduced in a simple manner. The auxiliary tube, relying on its own flexibility, allows the nozzle 130 to rotate along with the sleeve 151 while the main tube 141 remains stationary.

[0091] In one example of the present invention, it further includes: an on-off valve 180,

[0092] It is disposed between the pressure pump 120 and the nozzle 130 and is configured to switch the pressurized gas between the pressure pump 120 and the nozzle 130 on and off, thereby controlling the pressurized gas.

[0093] The exemplary implementation of the cement dust cleaning system 100 proposed in the present invention is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present invention, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present invention can be combined in various ways without exceeding the scope of protection of the present invention, which is determined by the appended claims.
