DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the embodiments of the present disclosure are further described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present disclosure and not to limit the embodiments of the present disclosure.
[0027] As Figure 1 shown, the flow guide device according to an embodiment of the present disclosure comprises a conical flow guide 100 arranged in the central region of the cyclone separator 300, and a plurality of first flow guide plates 200 are uniformly arranged on the side wall of the conical flow guide 100 along the direction of the cyclone flow, and the first flow guide plates 200 and the side wall of the conical flow guide 100 have a first preset space 220 therebetween, so that when the cyclone flows through the first flow guide plates 200, a vortex is formed in the first preset space 220.
[0028] The flow guide device according to an embodiment of the present disclosure is arranged in the cyclone separator, and the cyclone separator is mainly applied to an environmental protection powder coating grinding machine to control the particle size of the powder. The conical flow guide can be a conical flow guide. After the powder pieces are ground, the particles pass through the pipeline to the cyclone separator. During the separation process of the cyclone separator, the powder particles will impact the inclined surface of the "conical flow guide", forming a recoil force. Firstly, the original movement route of the powder particles in the cyclone separator can be changed. Secondly, the residence time of the powder particles in the cyclone separator can be increased.
[0029] To further increase the residence time of powder particles in the cyclone separator, and improve the particle separation efficiency, the side wall of the conical flow guide of the embodiment of the present disclosure is additionally provided with a plurality of first flow guide plates, and a first preset space is formed between the first flow guide plates and the side wall of the conical flow guide. The cyclone of the cyclone separator passes through the first flow guide plates, and a vortex is formed in the first preset space. The vortex can increase the residence time of powder particles in the cyclone separator, and further subdivide the coarse and fine particles. The coarse particles with a larger specific gravity stay in the first preset space for a longer time, and the fine particles are more easily sucked away by the induced draft equipment. The coarse particles with a larger specific gravity finally flow out of the discharge port of the cyclone separator, and the fine particles are sucked away by the induced draft equipment.
[0030] The flow guide device changes the movement route of the powder particles and increases the residence time of the powder particles, so that the induced draft filtration system of the flour mill can better suck away more superfine particles. The advantages of setting the flow guide device in the cyclone separator are as follows: 1. The particle size of the output is more uniform, and the product stability is improved. 2. The production time is saved, and the efficiency is improved. 3. The cost of replacing parts of the equipment is reduced.

[0032] The embodiment of the present disclosure can increase the residence time of powder particles in the cyclone separator by arranging a plurality of first flow guide plates.
[0033] As shown in Figure 2 , as a specific example of the first flow guide plate, one end of the first flow guide plate 200 is arranged on the side wall of the conical flow guide 100, and the other end extends in the cyclone direction to form a flow guide wall 210. The flow guide wall 210 and the side wall of the conical flow guide 100 have a first preset space 220 therebetween.
[0034] The cyclone passes through the flow guide wall at one end of the first flow guide plate, and when it reaches the first preset space, a vortex is formed in the first preset space, increasing the residence time of the powder particles. When the powder particles stay, more fine powder is sucked away, the coarse particles are separated out, and finally fall into the discharge port.
[0035] As shown in Figure 1 and Figure 2 , as a specific example of the flow guide wall, the shape of the flow guide wall 210 is arc-shaped or L-shaped.
[0036] The specific shape of the flow guide wall can be set according to actual conditions.

[0040] The mounting portion is uniformly provided with a plurality of mounting portions along the conical surface of the conical flow guide. The detachable mounting structure of the first flow guide plate of the present disclosure is simple, and the material of the first flow guide plate can be selected from high-density metals and the like. When in use, the clamping plate of the first flow guide plate is inserted into the mounting groove, and when disassembled, the first flow guide plate is directly pulled out.

[0044] That is, the central region and the inner wall of the cyclone separator are provided with guide plates, and arranging multiple guide plates can effectively improve the particle residence time. The cyclone flows through the second guide plate to form a vortex in the second preset space.

[0046] As shown in Figure 5 Another aspect of the embodiment of the present disclosure provides a cyclone separator, which comprises the guide device as described above, and the conical guide 100 is arranged in the central region of the cyclone separator 300.
[0047] When the guide device comprises the second guide plate, the second guide plate is arranged on the inner wall of the cyclone separator.
[0048] After the particles enter the cyclone separator, under the action of the guide device, the original movement path of the powder particles in the cyclone separator can be changed, and the residence time of the powder particles is also prolonged, more superfine particles enter the dust removal cabinet through the air guide channel, and the production efficiency of the finished product is improved.
