Description

TECHNICAL FIELD

[0002] In the food processing industry, the cleanliness and safety of the production environment are of great importance. With the increasing demand for food safety, there are more stringent standards for air quality in food processing plants. Dust not only affects the quality and taste of food, but also causes static reactions when it enters the processing equipment, which can damage the processing equipment and even cause safety accidents.

[0003] Currently, to solve the problems of dust and static electricity in the workshop, air filtration equipment and anti-static equipment are usually installed separately. Dust particles in the air are intercepted and adsorbed by air filtration equipment, and static charges in the air are neutralized by special anti-static equipment to eliminate static electricity.

[0004] However, the traditional air filtration equipment can only filter dust simply and cannot be effectively combined with the anti-static system, so it cannot solve the problems of dust and static electricity at the same time. It is inconvenient to use and difficult to meet the increasingly stringent requirements of the food processing industry for the production environment. In addition, the filter screen of the traditional air filtration equipment is easy to block after long-term use, which reduces the filtering efficiency and requires frequent replacement or removal of the filter screen for cleaning. It is inconvenient to use and increases the maintenance cost and workload.

The fixing member is connected to the shell 1, one end of the pawl is hingedly connected to the fixing member, the other end of the pawl cooperates with the ratchet wheel 534, and the two ends of the spring are connected to the pawl and the fixing member respectively. The spring has a pushing force on the pawl, so that the pawl is kept in contact with the ratchet wheel 534. The number of pawl groups 535 can be set as needed and can be distributed at intervals in the circumferential direction of the ratchet wheel 534.

[0052] As shown in Figure 2 , Figure 6 and Figure 8 , the shell 1 is provided with an upper mounting layer 14 and a lower mounting layer 15. The driving member 42, the upper sprocket 5182 and the vibration assembly can be arranged on the upper mounting layer 14, and the first gear 511, the rack 512, the second gear 513, the first bevel gear 516, the second bevel gear 517 and the lower sprocket 5181 can be arranged on the lower mounting layer 15. The upper mounting layer 14 and the lower mounting layer 15 form an air filtering space therebetween, so that air flows only in the air filtering space, thereby ensuring the filtering effect.

[0053] As shown in Figure 1 , Figure 2 and Figure 3 , optionally, the anti-static mechanism includes a metal mesh 31 and a grounding wire 32. The metal mesh 31 is arranged in the shell 1 and is arranged on the side of the first filtering mechanism away from the air inlet door 11, for intercepting and neutralizing static electricity in the air. One end of the grounding wire 32 is connected to the metal mesh 31, and the other end of the grounding wire 32 is grounded. The metal mesh 31 can timely conduct the static electricity accumulated thereon to the ground, thereby avoiding the accumulation of static electricity in the device and ensuring the safe and stable operation of the food processing anti-static dust removal device and preventing safety hazards caused by static electricity. The density of the metal mesh 31 can be set as needed, and the grounding wire 32 is a metal wire.

[0054] As shown in Figure 1 , Figure 2 and Figure 3As shown, the device further comprises a second filtering mechanism 6, which is arranged on the side of the air supply mechanism away from the first filtering mechanism, and can filter the air passing through the first filtering mechanism again to optimize the filtering effect. The horizontal distance between the second filtering mechanism 6 and the anti-static mechanism is sufficient to enable the air supply member 41 to rotate, reducing the risk of interference. The second filtering mechanism 6 can be a dust removal filter element, and the filtering precision of the second filtering mechanism 6 is greater than that of the first filtering mechanism, so as to achieve a better filtering effect. In the cleaning state, the reverse blowing can also achieve a certain cleaning effect on the second filtering mechanism 6, and because the filtering precision is greater than the first filtering precision, the impurities blown out by the second filtering mechanism 6 can be blown out through the first filtering mechanism, without affecting the cleaning effect.

[0055] It can be understood that the device further comprises necessary structures for connection, support, driving, positioning, limiting, sealing, and control, etc., so that the device can normally operate; the shape, size, material, and setting number of each part of the device can be determined according to needs, and the corresponding functions can be realized.

[0056] The implementation principle of the food processing anti-static dust removal device according to the embodiment of the present application is as follows: in the filtering state, the air supply member 41 enables the air to enter the shell 1 from the air inlet door 11, and the air is filtered by the first filtering mechanism to intercept the impurities such as dust in the air at the first filtering mechanism, and then the purified air flows out from the air outlet door 12, meeting the requirement of the food processing environment on air cleanliness; and the anti-static mechanism can prevent static electricity from being generated, avoiding affecting the normal operation of the device and the air filtering effect due to static electricity adsorbing dust. When it is necessary to clean the first filtering mechanism, the driving assembly drives the air supply member 41 to rotate to switch to the cleaning state, at which time the air flows into the air outlet door 12, flows to the air inlet door 11 after passing through the air supply mechanism, and realizes the reverse blowing cleaning of the first filtering mechanism. At the same time, since the transmission assembly is in transmission connection with the driving assembly and the cleaning member 52, the driving assembly drives the air supply member 41 to rotate, and the transmission assembly transmits power to the cleaning member 52, so that the cleaning member 52 scrapes the surface of the first filtering mechanism when the state of the air supply member 41 is switched, and scrapes off the dust and other impurities attached to the first filtering mechanism, thereby assisting in realizing the automatic cleaning of the first filtering mechanism and guaranteeing the continuous and effective filtering capability of the first filtering mechanism.

[0057] The above are the preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
