Description

Technical Field

[0001] The utility model relates to the technical field of crude salt production equipment, in particular to a crude salt dust removal device. Background Art

[0002] Coarse salt is crystallized from brine in seawater or salt wells, salt ponds, and salt springs through frying and drying. It is natural salt and unprocessed large-grain salt. When it is used, the coarse salt needs to be screened for subsequent processing.

[0003] The most commonly used screening method is manual screening, which is inefficient. Therefore, some manufacturers have begun to use screening equipment for automated operation. However, in the actual screening process, the coarse salt is not only accompanied by impurities, but its surface is also easily contaminated with dust. At the same time, during the screening process, some coarse salt is broken into extremely small particles and is easily blown up during the screening process. However, the existing screening equipment does not have a dust removal effect, so it is easy to cause dust to contaminate the coarse salt again. The dust is also very likely to affect the surrounding working environment. Utility Model Content

A large amount of dust will be generated during the screening process of coarse salt, and the dust contains salt powder, which not only easily causes secondary pollution, but also affects the surrounding working environment.

[0019] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0021] Combination Figure 1 and Figure 2 As shown, a coarse salt dust removal device comprises:

[0022] The box body 1 is a rectangular metal shell, with a feed port 11 on the top, and the bottom end of the box body 1 is an inverted cone, with a material guide port 12 at the center of the bottom surface;

[0023] The screening assembly 2 is composed of three filter plates 21 arranged at intervals in the upper and lower parts. The mesh apertures of the filter plates 21 are different and arranged obliquely, so as to achieve a rapid sorting effect according to the particle size of the coarse salt;

[0024] The exhaust assembly 3 is arranged on the side wall of the box body 1, and absorbs the dust raised during the material guiding process by exhausting air, so as to quickly collect the dust and carry out dust reduction treatment.

[0025] Specifically, the screening assembly 2 also includes a fixing frame 22 arranged around the inner wall of the box body 1. The fixing frame 22 is made of rubber material and is fixed to the inside of the box body 1 by bolts, and the inner annular surface is fixed to the filter plate 21.

[0026] In addition, in order to facilitate the filter plate 21 to collect the coarse salt or impurities screened out, the filter plate 21 should be arranged at an angle. At the same time, considering that the coarse salt on the filter plate 21 rolls during the screening process, its position tends to shift with the tilt direction of the screen plate. Therefore, multiple filter plates 21 arranged at intervals up and down should be arranged in a cross shape, so that they roll in opposite directions on the filter plate 21 below, thereby increasing the retention time on the filter screen and avoiding confusion in the grading process caused by excessive rolling.

[0027] At the same time, in order to enhance the lifting effect and prevent material accumulation during the filtering and grading process, a vibration motor should be set on the back of the filter plate 21. Multiple vibration motors are connected to the same controller, and the screening process is accelerated by vibration. At the same time, strong vibration can also quickly lift the dust attached to the material.

[0028] During the above-mentioned vibration process, since the coarse salt is granular, it has various shapes. Some granular coarse salt may just match the aperture size of the filter plate 21. In the actual filtration process, it is very likely to be stuck due to vibration. Therefore, an elastic rope 23 is provided on the back of the filter plate 21, and a rubber ball 24 is simultaneously provided at its bottom. Therefore, during the up and down vibration of the filter plate 21, the filter plate 21 will move up and down quickly, and at the same time, the rubber ball 24 will be pulled to continuously hit the filter plate 21, so that the coarse salt stuck in the holes of the filter plate 21 will come out, thereby effectively avoiding the occurrence of blockage.

[0029] The exhaust assembly 3 is composed of three exhaust pipes 31, and the three exhaust pipes 31 are arranged at intervals up and down, and one end of each of them extends horizontally and is connected to the inside of the box body 1, and the other end is gathered in the same pipe and connected to the dust reduction box 33. At the same time, an exhaust fan 32 is also arranged at the connection point. Therefore, in the above-mentioned vibration filtration process, the rapidly raised dust and coarse salt particle dust will be quickly extracted into the dust reduction box 33, and quickly reduced through the atomizing spray pipe for centralized treatment. At the same time, the box body should adaptively open a through hole on the side wall that is breathable to the outside world, so as to cooperate with the exhaust assembly to circulate the airflow.

[0030] Since dust moves upward when it is raised, each exhaust pipe 31 should be arranged above a filter plate 21 so that it can smoothly absorb the dust raised inside.

[0031] A material guide pipe 13 is arranged at the bottom of the discharge port 15 and the bottom of the material guide port 12 at the bottom of the box body 1. The material guide pipe 13 is connected to the collection box 14 for classifying and recovering coarse salt of different particle sizes.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
