[0002] In the production field of organic silica gel, the effective control of workshop environment is very important for product quality, production efficiency and personnel health, the organic silica gel production process involves the mixing, reaction and processing of multiple raw materials, during which a large amount of fine dust, volatile organic compounds and other harmful gases and odor substances will inevitably be produced, these pollutants diffuse in the workshop, not only will make the workshop air turbid, visibility reduces, more seriously, long-term exposure in such an environment, the operator is prone to respiratory diseases, skin allergies and other health problems, greatly influence the worker's work comfort and physical health condition, the traditional ventilation equipment when coping with the ventilation demand of organic silica gel production workshop, exposed many defects, common ventilation equipment adopts single fixed filter structure, for example, simple filter screen or filter core type filter, in the initial use stage, these filter devices can intercept dust and part of harmful gas to a certain extent, but with the production process, pollutants accumulate on the surface of filter medium, since the dust particles in the production process of organic silica gel often have small particle size, easily adhere and block the filter pore, make the ventilation resistance of filter device grow exponentially, this directly leads to sharp reduction of ventilation volume, the air in the workshop cannot be updated in time and effectively, the concentration of pollutants gradually increases, forms vicious circle, in order to maintain the ventilation effect, enterprises have to frequently replace filter devices, this process not only needs to purchase a large number of spare filter elements, increases material cost, and each replacement needs to stop operation, which undoubtedly interrupts the production process, reduces production efficiency, causes time and economic double loss, at the same time, the cleaning method of traditional filter device depends on manual disassembly and cleaning or replacement, the operation is complicated and the labor intensity is big, for some large ventilation systems, the disassembly and installation of filter device often need professional tools and many people to cooperate, further increase the difficulty and cost of maintenance. UTILITARIAN CONTENT

[0003] The utility model aims at providing a reverse blowing self -cleaning's organic silica gel production workshop ventilation equipment to solve the problem of poor cleaning method of ventilation equipment in the above background technology.

[0004] In order to achieve the above object, the utility model provides the following technical scheme: a reverse blowing self -cleaning's organic silica gel production workshop ventilation equipment, including ventilation pipeline, the inside of one end of ventilation pipeline is installed with ventilation fan, the side surface of ventilation pipeline is provided with switching filter mechanism, the rotation of switching filter mechanism is guaranteed to the stable filtration of the air discharged from ventilation pipeline;

[0005] The switching filter mechanism comprises a switching motor fixedly installed on the outer surface of the ventilation duct, and the output shaft of the switching motor is fixedly connected with a switching wheel, and the outer surface of the switching wheel is embeddedly installed with a filter plate.

[0006] Preferably, the outer surface of the switching wheel is in close contact with the inner surface of the ventilation duct, and the filter plates are evenly arranged on the side surface of the switching wheel.

[0007] The above technical solution enables the switching wheel to form a relatively sealed space with the ventilation duct during rotation, ensuring that air can only be filtered through the filter plate, and the uniform distribution of multiple filter plates enables continuous and stable switching of the filtering operation, improving the continuity and stability of ventilation and filtration.

[0008] Preferably, the outer surface of the ventilation duct is fixedly provided with a transfer cylinder, and the surface of the ventilation duct opposite to the lower end of the transfer cylinder is provided with a back blowing port, and the outer surface of the ventilation duct opposite to the back blowing port is fixedly provided with a baffle, the output shaft of the switching motor is fixedly connected with a drive gear, the surface of the baffle on one side of the drive gear is installed with a rotating transmission gear, and the rotating end of the transmission gear is fixedly connected with a poking gear, the upper end of the baffle is fixedly provided with a piston cylinder, the inside of the piston cylinder is installed with a sliding piston plate, and the lower surface of the piston plate is fixedly connected with a tooth rod, the upper and lower surfaces of the piston cylinder are both fixedly provided with an air inlet one-way valve and an air outlet one-way valve, the upper surface of the transfer cylinder is fixedly provided with an air inlet connector, and the air inlet connector and the air outlet one-way valve at one end of the piston cylinder are connected with a connecting pipe.

[0009] The above technical solution utilizes the rotation of the switching motor to drive the reciprocating motion of the piston plate in the piston cylinder through a series of gear transmissions, realizing the suction, compression and directional delivery of air, and providing a power source and an air flow path for the back blowing cleaning of the filter plate.

[0010] Preferably, the baffle is designed in an L shape, and the baffle is located between the back blowing port and the transmission gear.

[0011] The above technical solution provides a stable mounting base and protection for the transmission gear and other components, ensuring that the blown-off impurities do not affect the normal operation and stability of the transmission structure.

[0012] Preferably, the drive gear and the transmission gear are meshingly connected, and the transmission gear and the poking gear are designed in a concentric manner.

[0013] The above technical solution stably and efficiently transmits the power of the switching motor to the poking gear.

[0014] Preferably, the poking gear is designed with missing teeth, and the lower surface of the tooth rod opposite to the poking gear is evenly provided with tooth blocks.

[0015] By means of the toothless characteristic of the shifting gear and the cooperation with the toothed rod tooth block, intermittent reciprocating movement of the toothed rod is realized, thereby driving the piston plate to slide up and down in the piston cylinder periodically, and the air suction and compression process is accurately controlled, thereby providing stable and adjustable air flow supply for the back blowing cleaning.

[0018] Compared with the prior art, the organic silicone rubber production workshop ventilation equipment has the advantages that:

[0019] 1. By means of the unique design of the switching filter mechanism, uninterrupted and high efficiency of the ventilation and filtration process are realized, the switching motor drives the switching wheel to rotate, so that a plurality of filter plates are switched into the air flow channel of the ventilation pipeline in turn, and this rotation mode ensures that at any time, the filter plate in good filtering state purifies the discharged air, even if the filter plate gradually accumulates pollutants with the increase of the use time, and the filtering efficiency decreases, the system can switch to a new filter plate in time, so that the stable and efficient ventilation and purification capacity is always maintained;

[0020] 2. When the switching wheel rotates, the driving gear connected therewith drives the transmission gear and the shifting gear to move. Due to the toothless design of the shifting gear and the cooperation with the toothed rod, the toothed rod drives the piston plate to reciprocate up and down in the piston cylinder, in this process, the air inlet and outlet one-way valves on the piston cylinder work cooperatively, the air suction, compression and discharge are realized, the compressed air enters the transfer cylinder through the connecting pipe, and then the filter plate below the transfer cylinder is strongly back blown through the back blowing port. This back blowing and self-cleaning mode fully utilizes the power of the equipment itself, without the need for additional complex external cleaning equipment or large air supply system, thereby greatly reducing the operation cost and energy consumption of the equipment.

[0021] 3. The back blowing process can effectively remove the dust, impurities and other pollutants attached to the surface of the filter plate, so that the filtering performance of the filter plate can be quickly restored, which not only significantly prolongs the service life of the filter plate and reduces the replacement frequency of the filter plate, but also reduces the equipment downtime caused by the replacement of the filter plate, thereby improving the overall operation efficiency and production continuity of the production equipment.
