[0022] Specifically, please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the overall structure of the dust removal equipment for cementing material production provided in the embodiment of the present application. Figure 2This is a schematic diagram of the overall cross-sectional structure of the dust removal equipment for cementing material production provided in the embodiment of the present application. Figure 3 A schematic diagram of a local structure of a mesh plate provided in an embodiment of the present application, Figure 4 A schematic diagram of the local structure of the equalizing pipe provided in the embodiment of the present application. The dust removal equipment 100 for unloading cementing materials production includes a unloading box 110, which can be used in conjunction with the unloading box 110 for any operation such as mixing, stirring, and crushing the raw materials of the cementing materials. The bottom of the unloading box 110 is integrally connected with a connecting tube 120, and a flange is provided at the bottom end of the connecting tube 120. The size of the connecting tube 120 can be set according to the corresponding equipment. For example, when it is necessary to unload the mixer, the bottom diameter of the connecting tube 120 should be designed according to the feed inlet of the mixer. The cross-section of the unloading box 110 is square, and an annular lap joint 130 matching the unloading box 110 is provided on the inner wall near the top of the unloading box 110. The annular lap joint 130 is fixed in the inner cavity of the unloading box 110, and the annular lap joint 130 is close to the top end of the unloading box 110. The top of the annular lap joint 130 forms a lap platform 131, which is used to contact the mesh plate 140 and provide a certain support. Four mesh plates 140 are arranged on the lap platform 131, and the other end of the mesh plate 140 is tilted upward and connected to the top wall of the material box 110. The inner wall of the material box 110, the lap platform 131 and the mesh plate 140 together enclose an air suction chamber 150. During the process of material being discharged through the material box 110, the dust that is scattered is sucked out through the air suction chamber 150. A negative pressure dust removal box 160 is fixed to the outside of the material box 110. The negative pressure dust removal box 160 is connected to at least one negative pressure pipe 161, which is connected to the air suction chamber 150. The negative pressure pipe 161 uses negative pressure to suck the dust in the air suction chamber 150 into the negative pressure dust removal box 160. A filter bag 162 is provided on one side of the negative pressure dust removal box 160. The filter bag 162 can be purchased on the market and is used to separate powder from gas. The filter bag 162 is connected to a negative pressure fan 163. The negative pressure fan 163 is used to generate negative pressure in the negative pressure dust removal box 160, so that the dust spilled from the top of the unloading box 110 when unloading is sucked into the negative pressure dust removal box 160 by using the negative pressure pipe 161 and the suction cavity 150. The dust is separated by the bag filter and remains in the negative pressure dust removal box 160, and the gas is discharged from the air outlet of the negative pressure fan 163. An electromagnetic gate valve 164 is provided at the bottom of the negative pressure dust removal box 160, and the electromagnetic gate valve 164 is connected to the inner cavity of the discharge box 110. When the material in the negative pressure dust removal box 160 accumulates to a certain amount, the negative pressure fan 163 can be closed and the electromagnetic gate valve 164 can be opened. At this time, the material accumulated in the electromagnetic gate valve 164 will enter the discharge box 110.

[0023] As can be seen from the above, in the embodiment of the present application, by setting the annular lap joint 130 and the mesh plate 140 on the inner side of the material box 110, the annular lap joint 130, the mesh plate 140 and the inner wall of the material box 110 together form an air suction chamber 150, and the air suction chamber 150 acts on the four sides of the material box 110, so that when the material is discharged to the material box 110, the spilled dust will be sucked into the air suction chamber 150 around the material box 110, thereby reducing the dust content in the factory area, and because the present application directly acts on the dust generation site, the dust removal effect is better than other dust removal equipment. On the other hand, the present application sets a negative pressure dust removal box 160 and uses it with a negative pressure fan 163, so that the material in the air suction chamber 150 can be sucked into the negative pressure dust removal box 160 for storage, so that the collected dust can be re-injected into the material box 110 in the form of opening the electromagnetic gate valve 164 later, thereby avoiding the waste of raw materials and reducing costs.

[0024] In some embodiments, there are multiple negative pressure pipes 161, and the multiple negative pressure pipes 161 are respectively connected to the air suction chamber 150 after passing through multiple side walls of the material box 110. In the embodiment of the present application, through the above-mentioned setting, the negative pressure pipe 161 is set according to the number of sides of the material box 110, and the cross-section of the material box 110 is a quadrilateral. Correspondingly, the number of negative pressure pipes 161 is four, and the four negative pressure pipes 161 are respectively inserted into the side of the material box 110 and then connected to the air suction chamber 150, so that the negative pressure generated at each position in the air suction chamber 150 is more uniform, so that the dust can be more effectively adsorbed.

[0025] In some embodiments, the negative pressure dust removal box 160 is detachably fixed to the discharge box 110, and multiple negative pressure tubes 161 are detachably fixed to the negative pressure dust removal box 160 through connecting sleeves 165, and the bottom of the negative pressure dust removal box 160 forms an inclined discharge platform 166. In the embodiment of the present application, through the above arrangement, the operator can remove the negative pressure dust removal box 160 from the discharge box 110 for cleaning or replacement after removing the corresponding negative pressure tube 161, and the bottom of the negative pressure dust removal box 160 forms an inclined discharge platform 166 to facilitate the complete introduction of dust in the negative pressure dust removal box 160 into the discharge box 110.

[0026] In some embodiments, the top of the mesh 140 is folded outward to form a U-shaped connecting end 141, and corresponding threaded holes are provided at the connecting end 141 and on the outer wall of the material box 110, and screws are provided in the threaded holes. In the embodiment of the present application, through the above-mentioned arrangement, the mesh 140 and the material box 110 will be detachably connected, and during the installation process, the mesh 140 only needs to be placed in a suitable position and then it can be conveniently fixed by screws. In some embodiments, the side of the lap platform 131 away from the material box 110 forms an arc-shaped abutting end 131a, and the side of the bottom end of the mesh 140 close to the lap platform 131 forms an arc-shaped groove 142 matching the arc-shaped abutting end 131a, and the arc-shaped abutting end 131a extends into the arc-shaped groove 142. In the embodiment of the present application, through the above-mentioned setting, the mesh plate 140 and the overlapping platform 131 will be in an active connection, and the two will only abut against each other but not be fixed. On the one hand, it is convenient for fixation, and on the other hand, when the present application is used in conjunction with the vibration motor 170, the vibration amplitude of the mesh plate 140 will be larger, thereby facilitating shaking off the material on the top of the mesh plate 140.

[0027] In some embodiments, a vibration motor 170 is provided at the connection tube 120, and the vibration end of the vibration motor 170 abuts against the outer wall of the connection tube 120. In the embodiment of the present application, by providing the vibration motor 170, on the one hand, the accumulation of materials in the material box 110 is avoided, and on the other hand, the materials dropped at the mesh plate 140 can be vibrated so that the materials are separated from the mesh plate 140 and slide downward into the material box 110.

[0028] In some embodiments, a pressure equalizing tube 167 is included, the pressure equalizing tube 167 is transversely arranged in the air suction chamber 150, the pressure equalizing tube 167 is connected to the negative pressure tube 161, and a plurality of air inlets 167a are arranged on the pressure equalizing tube 167 along the axial direction of the pressure equalizing tube 167. In the embodiment of the present application, by providing the pressure equalizing tube 167, the air inlets 167a on the negative pressure tube 161 can be evenly arranged in the air suction chamber 150, so that negative pressure can be generated more stably and evenly in various places of the air suction chamber 150, and the dust removal effect will be further enhanced.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
