Description

Technical Field

[0001] The utility model relates to the technical field of ultrafine pulverizers, in particular to an impurity removal mechanism for ultrafine pulverizers. Background Art

[0002] Ultrafine pulverizer is a kind of equipment that uses air separation, heavy pressure grinding, shearing and other forms to achieve ultrafine grinding of dry materials. The whole system is generally composed of silo, mechanical pulverizer, induced draft fan, cyclone, vibrating screen, liquid nitrogen tank, etc. Working principle: Ultrafine pulverizer uses air separation, heavy pressure grinding, shearing and other forms to achieve ultrafine grinding of materials. In the air flow pulverizing host, the high-pressure air generated by the air compressor is instantly released into the inside of the pulverizing host through the air flow nozzle of the pulverizer. Driven by the high-pressure air, the materials collide with each other inside the pulverizing host to achieve the purpose of pulverization;

[0003] When using an ultrafine pulverizer, a negative pressure fan is also required to suck the raw materials into the ultrafine pulverizer through a suction pipe for pulverization. However, the traditional suction pipe directly sucks the raw materials away without screening the raw materials, thereby screening out metals and other impurities in the raw materials, thereby affecting the quality of pulverization. Therefore, an ultrafine pulverizer is needed to use an impurity removal mechanism to solve the above problems. Utility Model Content

[0004] The utility model aims to provide an impurity removal mechanism for an ultrafine pulverizer, so as to solve the defect that it is inconvenient to remove impurities from raw materials when the raw materials are sucked into the ultrafine pulverizer through a suction pipe.

[0007] Preferably, two groups of springs are provided, and the two groups of springs are symmetrically distributed on one side of the screening grid.

[0008] Preferably, one side of the spring is connected to the spring plate, and a tensile structure is formed between the spring and the spring plate.

[0011] Preferably, a plurality of the bolts are provided, and the plurality of the bolts are distributed in a ring shape at the top end of the first flange.

[0012] The utility model provides a kind of impurity removal mechanism for ultrafine pulverizer, which has the advantages of:

[0013] By setting the impurity outlet, when the raw material passes through the impurity removal pipe, the metal impurities inside it will directly fall into the impurity outlet because they are heavier than the original material. And by using the screening grid, since its filter holes are only slightly larger than the raw material particles, only the raw material can pass through, while other impurities in the raw material will be screened out and fall into the impurity outlet, thus completing the impurity removal work.

[0014] Furthermore, when it is necessary to clean the raw materials stuck on the screening grid, through the cooperation of the spring and the spring plate, when the screening grid is taken out, the spring plate can be pulled, and then the spring plate will hit the screening grid according to the return force of the spring to drive the internal screening net to vibrate, and the raw materials stuck on the screening net will be cleaned off, making it more convenient to clean the raw materials stuck on the screening net, thereby improving the cleaning efficiency.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model embodiment provides a kind of impurity removal mechanism for superfine pulverizer, such as Figure 1-Figure 5 As shown, a superfine pulverizer impurity removal mechanism includes an impurity removal tube 1 and a feed tube 3; a feed port 2 is provided at the top of the impurity removal tube 1, a feed tube 3 is provided at the top of the feed port 2, a sealing structure 7 is provided at the connection between the feed port 2 and the feed tube 3, a suction tube 5 is provided on one side of the impurity removal tube 1; an impurity outlet 6 is provided at the bottom of the impurity removal tube 1, and an impurity removal structure 4 is provided inside the impurity removal tube 1

[0023] Specifically, in this embodiment: when using the impurity removal pipe 1, the impurities in the raw material can be removed by setting the impurity removal structure 4 to make the raw material cleaner, and the sealing structure 7 can be set to enhance the sealing of the connection between the feed port 2 and the feed pipe 3 so that there will be no leakage at the connection when sucking the material.

[0024] In a further preferred embodiment of the present invention, Figure 1-Figure 5 As shown: the impurity removal structure 4 includes a screening grid 401, a spring 402, a spring plate 403, a connecting rod 404, a mounting plate 405 and a handle 406. The screening grid 401 is arranged on one side of the impurity removal pipe 1. The two ends of one side of the screening grid 401 are provided with springs 402, and one side of the spring 402 is provided with a spring plate 403. The two ends of the other side of the screening grid 401 are provided with connecting rods 404, and one side of the connecting rod 404 is provided with a mounting plate 405. One side of the mounting plate 405 is provided with a handle 406.

One side of the spring 402 is connected to the spring plate 403, and a tensile structure is formed between the spring 402 and the spring plate 403.

[0025] Specifically, in this embodiment: when removing impurities from the raw material, the suction pipe 5 is connected to the ultrafine pulverizer and a suction operation is performed. When the raw material enters the interior of the impurity removal pipe 1 through the feed pipe 3, the heavier metal impurities inside it will directly fall into the interior of the impurity outlet 6 to perform preliminary impurity removal work, and when the raw material encounters the screening grid frame 401, the internal screening net will perform a secondary screening on the raw material to screen out other impurities in the raw material and drop them into the interior of the impurity outlet 6. Since the filter holes of the screening net are only slightly larger than the raw material particles, only the raw material can pass through, thereby completing the impurity removal work. When it is necessary to clean the raw material and impurities adhering to the screening net inside the screening grid frame 401, the screening grid frame 401 is pulled out, and then the spring plate 403 is pulled and then released, so that the spring plate 403 hits the screening net under the action of the spring 402, causing the screening net to vibrate, thereby vibrating the adhering raw material and impurities off, making it more convenient to clean.

[0026] In a further preferred embodiment of the present invention, Figure 1-Figure 5 As shown: the sealing structure 7 includes a first flange 701, a second flange 702, a sealing ring 703 and a bolt 704.

The sealing ring 703 is installed in the middle of the sealing ring 703 and the second flange 702. The bolt 704 is arranged at the top of the first flange 701. The bolt 704 penetrates the first flange 701 and is inserted into the interior of the second flange 702. A threaded connection is formed between the bolt 704 and the second flange 702. A plurality of bolts 704 are arranged, and the plurality of bolts 704 are distributed in a ring shape at the top of the first flange 701.

[0027] Specifically, in this embodiment, before sucking the material, the sealing ring 703 is installed at the connection between the feed port 2 and the feed pipe 3, and then fixed by a bolt 704. At this time, the use of the sealing ring 703 can enhance the sealing of the connection between the feed port 2 and the feed pipe 3, so that there will be no leakage at the connection when sucking the material, thereby completing the sealing work.
