Description

Technical Field

[0001] This utility model relates to the field of iron removal equipment technology, and in particular to an auxiliary iron removal device for cement mills. Background Technology

[0002] Cement mills are key equipment for further pulverizing materials after they have been crushed. When using cement mills, it is necessary to remove iron from the fine powder after grinding to prevent the return chute of the cement mill from getting clogged. Therefore, in the existing technology, a professional iron removal device is usually used to filter the iron powder.

[0003] For example, in the prior art, there is an auxiliary iron removal device for a cement mill, patent number: CN218573911U. This auxiliary iron removal device for a cement mill is installed at the return chute of the cement mill by means of a mounting bracket. The drive motor in the drive assembly drives the rotating shaft and magnetic roller to rotate through the drive wheel, transmission belt and driven wheel. The magnetic roller adsorbs the iron powder in the fine powder. The iron powder adsorbed on the magnetic roller is hung off by the discharge inclined plate and enters the discharge inclined pipe. At the same time, the suction assembly is activated, so that the fine powder carried by the iron powder enters the discharge pipe through the recovery pipe, fixed pipe, adsorption pipe and connecting pipe. The discharge pipe enters the large filter bag of the air classifier for negative pressure dust collection, which realizes the goal of convenient iron removal and fine powder recovery of the cement mill.

[0004] However, in the existing technology, simply using magnetic rollers to adsorb iron powder in cement powder cannot improve the filtration degree of iron powder. Furthermore, using suction components to transport and clean cement powder cannot control the rate at which cement powder enters the iron removal device, which can easily cause dust to spread through various pipes and cause blockages, or even flow out of the pipes, causing losses and hazards. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing an auxiliary iron removal device for cement mills.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, an auxiliary iron removal device for a cement mill includes a device housing. The upper surface of the device housing has a rotating through-hole and a feed trough, with the inner diameter of the rotating through-hole being smaller than the inner diameter of the feed trough. A conical rotating cylinder is rotatably connected within the rotating through-hole. A hollow tube is fixedly connected between the rotating through-hole and the feed trough, and located on the upper surface of the device housing. A motor with a main shaft fixedly connected to the conical rotating cylinder is installed inside the hollow tube. A conical feed inlet is fitted onto the outer surface of the hollow tube. A drag handle is provided on the outer surface of the conical feed inlet. An annular stop is provided on the outer surface of the hollow tube, at the gap between the bottom of the conical feed inlet and the hollow tube. Two rows of slide rails are provided at the bottom of the device housing, with a receiving trough slidably connected within each slide rail. Several electromagnets are inserted into both sides of the inner wall of the device housing.

[0008] Preferably, two clamping blocks are symmetrically arranged on the inner wall of the hollow tube.

[0009] Preferably, a receiving plate is rotatably connected inside the outer casing of the device and between the conical rotating cylinder and the receiving trough, and a rotating disk is fixedly connected to the rotating shaft of the receiving plate extending outward through the outer casing of the device.

[0010] Preferably, a connecting handle is fixedly connected to the end face of the electromagnet.

[0011] Preferably, a rotating baffle is rotatably connected to the opening of the device housing.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the amount of cement powder fed at one time can be controlled by first pulling the drag handle to separate the conical feed inlet and the annular stop block. Then, the motor drives the conical drum to rotate and impact the fed cement powder so that it is evenly sprinkled on the electromagnet and the iron powder in the cement powder is adsorbed, thereby reducing the iron powder content in the cement powder.

[0014] 2. In this utility model, by setting a guide rail and a receiving trough on the inner wall of the bottom of the device shell, the cement fine powder after the iron removal process can be collected by pulling the receiving trough. At the same time, in order to improve the iron removal effect, the receiving trough can be pulled and the cement fine powder collected in the receiving trough can be poured back into the conical feed port of the device for filtration again.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figure 1-4 As shown, an auxiliary iron removal device for a cement mill includes a housing 1. A rotating through-hole 2 and a feed trough 4 are provided on the upper surface of the housing 1, with the inner diameter of the rotating through-hole 2 being smaller than the inner diameter of the feed trough 4. A conical rotating cylinder 3 is rotatably connected inside the rotating through-hole 2. A hollow tube 5 is fixedly connected between the rotating through-hole 2 and the feed trough 4, and located on the upper surface of the housing 1. A motor 6, with its main shaft fixedly connected to the conical rotating cylinder 3, is installed inside the hollow tube 5. A conical feed inlet 8 is fitted onto the outer surface of the hollow tube 5. A drag handle 7 is provided on the outer surface of the conical feed inlet 8. An annular stop block 11 is provided on the outer surface of the hollow tube 5, at the gap between the bottom of the conical feed inlet 8 and the hollow tube 5. Two rows of slide rails 17 are provided at the bottom of the housing 1, with a receiving trough 9 slidably connected inside each slide rail 17. Several electromagnets 10 are inserted into both sides of the inner wall of the housing 1.

[0023] Further explanation of this solution: When using the auxiliary iron removal equipment, the power is turned on, and the motor 6 inside the hollow tube 5 drives the conical drum 3 to rotate and add cement powder containing iron powder into the conical feed inlet 8. Pulling the drag handle 7 upwards separates the bottom of the conical feed inlet 8 from the annular stop block 11. The cement powder slides down the inner wall of the conical feed inlet 8 and enters the device shell 1 through the feed trough 4. The conical drum 3 rotates and impacts the cement powder, causing it to be evenly sprinkled onto the electromagnet 10 on the inner wall of the device shell 1. The electromagnet 10 adsorbs the iron powder in the cement powder, and the cement powder is collected in the receiving trough 9, thus realizing the removal of iron from the cement powder.

[0024] Meanwhile, in order to further ensure the iron removal effect of the device, after a single iron removal operation is completed, the receiving trough 9 can be pulled out along the slide rail 17, and the cement powder inside the receiving trough 9 can be poured back into the conical feed inlet 8. The above operation is repeated to complete the iron removal process again and reduce the iron powder content in the cement powder.

[0025] like Figure 1 As shown, two clamping blocks 12 are symmetrically arranged on the inner wall of the hollow tube 5.

[0026] The purpose of this solution is to fix the position of the motor 6 when the motor 6 drives the conical drum 3 to rotate in the hollow tube 5 by setting the clamping block 12, so as to prevent the motor 6 from rotating inside the hollow tube 5 and affecting the normal operation of the device.

[0027] like Figure 2 and Figure 3 As shown, inside the device housing 1, and between the conical rotating cylinder 3 and the receiving trough 9, there is a receiving plate 13 rotatably connected. The rotating shaft of the receiving plate 13 passes through the end face of the device housing 1 extending outward and is fixedly connected to a rotating disk 14.

[0028] The purpose of this solution is as follows: when cement powder slides into the device housing 1 along the inner wall of the conical feed inlet 8, some of the iron powder in the cement powder is impacted and adsorbed onto the electromagnet 10 by the conical rotating drum 3. The remaining small amount of iron powder falls onto the receiving plate 13 along with the cement powder. At this time, the remaining cement powder on the receiving plate 13 can be made to slide again along the upper surface of the receiving plate 13 to the inner wall on both sides where the electromagnets 10 are set, by swinging the rotating disk 14 back and forth. This achieves secondary recycling and filtration of the remaining iron powder in the cement powder, further improving the iron removal efficiency.

[0029] like Figure 1 As shown, a connecting handle 15 is fixedly connected to the end face of the electromagnet 10;

[0030] A rotating baffle 16 is rotatably connected to the opening of the outer casing 1 of the device.

[0031] Further explanation of this solution: By setting the connecting handle 15, when cleaning the iron powder and other substances adsorbed on the outer surface of the electromagnet 10, the connecting handle 15 is pulled directly. Based on the gap between the electromagnet 10 and the plug interface, the iron powder and other useless substances are squeezed and separated from the outer surface of the electromagnet 10, thereby cleaning the electromagnet 10.

[0032] Meanwhile, by setting a rotating baffle 16, cement powder is prevented from spreading to the outside of the device due to the impact of the conical rotating drum 3 during operation, thus avoiding leakage and potential danger.

[0033] Working principle: When the device is powered on, iron-containing cement powder is added into the outer shell 1 of the device through the conical feed port 8. The motor 6 drives the conical drum 3 to rotate and impacts the cement powder entering the outer shell 1 onto the electromagnets 10 on both sides of the device. The electromagnets 10 adsorb the iron filings in the cement powder. After the iron removal operation is completed, the cement powder slides down the inner wall of the outer shell 1 and is finally collected in the receiving trough 9, thus realizing the iron removal operation.

[0034] The wiring diagrams of the motor 6 and electromagnet 10 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the motor 6 and electromagnet 10 will not be explained in detail.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
