Description

Technical Field

[0001] The utility model relates to the technical field of vertical mills, and in particular, to a screening structure and a vertical mill production system having the same. Background Art

[0002] A vertical mill is a widely used grinding equipment, mainly used for crushing granular materials into fine powder. In many industries, such as building materials, chemical industry, metallurgy, mining, etc., the application of vertical mills is very extensive. The secondary processing of screening powder in a vertical mill is to further screen and process the powder after preliminary crushing to meet the requirements of particle size and fineness of materials in different application fields. According to the different requirements of application fields, the powder can be customized processed and treated. In the prior art, a circulating fan is generally installed at the discharge port of the vertical mill to suck the ground material through the fan to form an air flow. After the material passes through the fan, a preliminary screening can be carried out. The coarse particles return to the inside of the mill for re-grinding, and the fine particles enter the next process.

[0003] However, the overall adaptability of the vertical mill that uses a fan to screen and extract materials is poor. Due to the space limitation of the vertical mill, for some materials with larger particle sizes, the expected screening effect may not be achieved, and there may still be some larger particles in the powder, which cannot fully meet the production requirements. Moreover, during the screening process, a large amount of electric energy is consumed, and some materials may accumulate in certain parts, resulting in equipment blockage and affecting production efficiency.

[0021] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0022] In order to solve the problem in the prior art that it is difficult for a vertical mill to screen materials with a relatively large particle size, resulting in poor screening effect, the present utility model provides a screening structure and a vertical mill production system having the same.

[0023] Please refer to Figure 1 As shown, in one aspect of applying the technical solution of the present utility model, a screening structure is provided for connecting with a vertical mill 1. The vertical mill 1 has a secondary feed inlet 2. The screening structure includes a storage bin 10, a mounting assembly 20, and a screening component 50. The mounting assembly 20 includes a conducting pipe 30 and a diverting pipe 40 that are connected to each other. One end of the conducting pipe 30 is connected to the storage bin 10. The diverting pipe 40 includes a first pipe section 41 and a second pipe section 42. The first pipe section 41 is connected to the secondary feed inlet 2, and the second pipe section 42 communicates with the middle of the conducting pipe 30. The screening component 50 is movably arranged between the conducting pipe 30 and the diverting pipe 40 to screen the materials flowing through the conducting pipe 30 in the storage bin 10, so that the materials passing through the screening component 50 flow back into the conducting pipe 30, and the materials not passing through the screening component 50 flow into the vertical mill 1.

[0024] In one aspect of applying the technical solution of this embodiment, when materials with different particle sizes in the storage bin 10 flow into the diverting pipe 40 through the conducting pipe 30, the screening component 50 screens the materials. Then, some of the screened materials flow into the second pipe section 42 and flow back into the conducting pipe 30, while the unscreened materials, which are the materials that need secondary processing, are located on the screening component 50. After that, they flow into the first pipe section 41 and then into the vertical mill 1 for secondary processing of abrasives, thereby solving the problem in the prior art that it is difficult for the vertical mill 1 to screen materials with a relatively large particle size, resulting in poor screening effect.

[0025] In this embodiment, the mounting assembly 20 further includes a connecting pipe 60. Opposite ends of the connecting pipe 60 are respectively connected to the conducting pipe 30 and the diverting pipe 40. The screening component 50 is movably arranged at the connection of the connecting pipe 60, the first pipe section 41, and the second pipe section 42, so that the materials screened by the screening component 50 flow into the first pipe section 41 and the second pipe section 42 respectively. In this way, after materials with different particle sizes flow through the conducting pipe 30 and the connecting pipe 60 in sequence and are screened by the screening component 50, the materials with too large particle sizes that need secondary processing remain on the screening component 50. Then, they are transported into the first pipe section 41 and flow into the vertical mill 1 through the secondary feed inlet 2 for secondary processing of abrasives.

[0026] Specifically, a spherical pipe section 61 is provided at one end of the connecting pipe 60. The first pipe section 41 and the second pipe section 42 are respectively connected to the spherical pipe section 61, and the connection point between the first pipe section 41 and the second pipe section 42 is the center of the spherical pipe section 61. The screening component 50 is movably connected to the connection point between the first pipe section 41 and the second pipe section 42 and respectively blocks the pipe orifices of the first pipe section 41 and the second pipe section 42. With the above settings, the end parts of the screening component 50 are respectively in contact with the inner wall of the spherical pipe section 61 and are movably arranged to respectively close the first pipe section 41 and the second pipe section 42. In this way, after the screening component 50 screens the materials with larger particle sizes, the screening component 50 is controlled to move to a position where the first pipe section 41 is opened, so that the materials remaining on the screening component 50 can flow into the first pipe section 41.

[0027] Specifically, the screening component 50 is a circular sieve plate, and the screening component 50 is rotatably arranged around the center of the spherical pipe section 61 so that the connecting pipe 60 is communicated with the first pipe section 41 or the second pipe section 42. In this way, when the screening component 50 screens materials with different particle sizes, the materials with smaller particle sizes directly flow into the second pipe section 42 through the screening component 50 and then flow back into the conduction pipe 30, while the materials with larger particle sizes remain on the screening component 50. After that, the screening component 50 is turned to an inclined state to open the pipe orifice of the first pipe section 41, so that the materials on the screening component 50 slide off the screening component 50 into the first pipe section 41 and then flow into the vertical mill 1 for secondary processing.

[0028] In an exemplary embodiment of the present application, a plurality of sieve holes are provided on one end face of the screening component 50 close to the second pipe section 42, and the plurality of sieve holes are respectively communicated with the second pipe section 42, so that the materials passing through the plurality of sieve holes flow back into the conduction pipe 30 through the second pipe section 42. In this way, after the materials flow into the spherical pipe section 61 through the connecting pipe 60, a part of the materials with smaller particle sizes respectively pass through the plurality of sieve holes and directly flow into the second pipe section 42, and then flow back into the conduction pipe 30.

[0029] In another exemplary embodiment of the present application, a sliding layer is provided on the screening component 50 to avoid the plurality of sieve holes, and the sliding layer is made of polyethylene material. In this way, after the screening component 50 screens the materials and the materials with larger particle sizes remain on the screening component 50, by controlling the screening component 50 to turn to a position where the first pipe section 41 is opened, under the action of the sliding layer, the materials on the screening component 50 slide into the first pipe section 41 and then flow into the vertical mill 1 for processing.

[0030] In this embodiment, a fan component is provided on the conduction pipe 30 for conveying the materials through the conduction pipe 30 to the shunt pipe 40. In this way, when screening the materials in the storage bin 10, the materials can be pumped from the conduction pipe 30 into the spherical pipe section 61 by controlling the fan component.

[0031] Optionally, a detection component is provided on the screening component 50 for detecting the particle size of the material located on the screening component 50. In this way, after the screening component 50 screens the material, some of the materials with larger particle sizes that need to be reprocessed will remain on the screening component 50. Then, the detection component is used to detect the material located on the screening component 50. If it is detected that the particle size of the material located on the screening component 50 is not too large, the screening component 50 is controlled to perform a slight left-right flipping and swinging motion (without opening the first pipe section 41 and the second pipe section 42) to perform another screening on the materials with larger particle sizes located on the screening component 50, greatly improving the screening effect of the screening component 50 and the screening accuracy.

[0032] Specifically, the conduction pipe 30 is arranged in the vertical direction, and a storage component 31 is provided at the bottom end of the conduction pipe 30. The screening structure further includes a moving assembly 70. A collection component 71 is provided on the moving assembly 70. The collection component 71 is located below the storage bin 10 for collecting the materials in the storage bin 10. At least part of the moving assembly 70 is movably arranged to drive the collection component 71 to move above the storage component 31 and pour the materials into the storage component 31. In this way, the collection component 71 sequentially picks up and collects the materials in the storage bin 10 and transports them to a position close to the storage component 31 on the conduction pipe 30, so as to facilitate the transfer of the materials in the collection component 71 into the storage component 31. And, through the design of the storage component 31, the materials with smaller particle sizes that pass through the multiple sieve holes on the screening component 50 flow into the second pipe section 42 and then flow back to the conduction pipe 30 and are directly collected in the storage component 31, facilitating the subsequent collection and storage of the materials.

[0033] Specifically, the moving assembly 70 includes a moving body 72. A conveyor is movably provided on the moving body 72. The collection component 71 is located on the conveyor. One end of the moving body 72 close to the conduction pipe 30 is provided with a tipping platform 73, so that the collection component 71 moves to the tipping platform 73 for tipping. With the above arrangement, the conveyor is a conveyor belt. In this way, the collection component 71 collecting the materials is transported to the tipping platform 73 through the conveyor belt, and then the collection component 71 is operated to tip the materials into the storage component 31 at the tipping platform 73 for screening treatment.

[0034] On another aspect of applying the technical solution of the present utility model, a vertical mill production system is provided, including the above-mentioned screening structure and a vertical mill 1, and the screening structure is connected to the vertical mill 1.

[0035] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

[0036] The screening structure is used to connect with a vertical mill 1, and the vertical mill 1 has a secondary feed inlet 2. The screening structure includes a storage bin 10, a mounting assembly 20, and a screening component 50. The mounting assembly 20 includes a conduction pipeline 30 and a diversion pipeline 40 that are connected to each other. One end of the conduction pipeline 30 is connected to the storage bin 10. The diversion pipeline 40 includes a first pipe section 41 and a second pipe section 42. The first pipe section 41 is connected to the secondary feed inlet 2, and the second pipe section 42 communicates with the middle of the conduction pipeline 30. The screening component 50 is movably arranged between the conduction pipeline 30 and the diversion pipeline 40 to screen the materials flowing through the conduction pipeline 30 in the storage bin 10, so that the materials passing through the screening component 50 flow back into the conduction pipeline 30, and the materials not passing through the screening component 50 flow into the vertical mill 1. In this way, when materials of different particle sizes in the storage bin 10 flow into the diversion pipeline 40 through the conduction pipeline 30, the screening component 50 screens the materials. Then, some of the screened materials flow into the second pipe section 42 and flow back into the conduction pipeline 30, while the unscreened materials indicate the materials that need secondary processing. They are located on the screening component 50 and then flow into the first pipe section 41 and then into the vertical mill 1 for secondary processing of abrasives, thus solving the problem in the prior art that it is difficult for the vertical mill 1 to screen materials with larger particle sizes, resulting in poor screening effects.
