Abstract
Description
Technical Field
[0001] The utility model relates to the field of grinding rooms, in particular to an explosion-proof grinding room. Background Art
[0002] Grinding, as an indispensable part of modern industrial production, is widely used in many fields such as metal processing, plastic products, and automobile parts manufacturing. Its main function is to remove burrs, rust, and polish metal workpieces to meet the surface finish and precision requirements of the products. Traditional grinding operations are generally carried out directly in workshops or open areas, and the dust pollution problem generated during grinding is serious. Therefore, the existing grinding room came into being.
[0003] The grinding room, as an environmental protection equipment in industrial production, is mainly used to collect and purify the dust generated during the grinding and polishing of workpieces. According to the on-site conditions, the grinding and dust removal device is designed as a room. The grinding room usually adopts a steel structure frame and is covered with steel plates or insulation boards to form a closed working space. The grinding operation area is isolated from the external environment through a fully enclosed or semi-enclosed design, and an explosion-proof ventilation system is configured to remove harmful gases and dust generated during the operation, thereby ensuring the air quality of the working environment and achieving the purpose of protecting the environment and protecting the health of workers.
[0004] However, the existing grinding rooms still have some defects in actual use. First, due to the large amount of dust generated during the grinding operation, there is still a certain amount of dust pollution under the operation of the existing dust collection device and air purification system. Under the accumulation of a large amount of dust, and in some extreme conditions, such as high temperature, high pressure, strong electricity, etc., it is very easy to cause explosion accidents in the grinding room or pipeline, and there are certain safety hazards. When an explosion occurs, the existing grinding room is prone to secondary or even multiple explosions through the pipeline, causing the explosion shock wave to injure people or damage equipment. Secondly, the operating efficiency of the existing explosion-proof grinding room is relatively low, and the internal ventilation effect of the grinding room is poor, resulting in an excessively high concentration of dust inside, which is prone to combustion and explosion when encountering sparks, thereby affecting the safe use of users inside their grinding rooms. Utility Model Content

[0008] In the above description, the partition layer is arranged on the top of the room body, the dust collection slot and the ventilation slot are both opened on the top of the room body, the dust collection hood and the ventilation hood are both installed on the top of the room body, and the dust collection hood and the ventilation hood are respectively connected and paired with the dust collection slot and the ventilation slot. Due to the pairing of the dust collection hood and the dust collection slot, the dust-containing gas in the workroom flows to the top of the room body, thereby passing through the dust collection slot into the dust collection hood, and completing the dust removal work through the corresponding pipeline.
[0009] Further in the above description, the explosion-proof isolation valve is installed on the interval layer through a support frame, one end of the explosion-proof isolation valve is connected to the dust removal pipe, and the other end of the explosion-proof isolation valve is connected to the dust removal connecting pipe, an isolation flap is provided in the explosion-proof isolation valve, and the end of the isolation flap is rotatably installed in the explosion-proof isolation valve through a rotating shaft, and one end of the rotating shaft extends outside the explosion-proof isolation valve and is connected to a driving handle.
[0010] The purpose of the explosion-proof isolation valve is that when an explosion occurs, the explosion-proof isolation valve can sense the explosive airflow and cut off the pipeline instantly, preventing the explosive airflow from being directed along the pipeline into the explosion-proof dust collector and the room, thereby preventing secondary or even multiple explosions, or the explosion shock wave from injuring people or damaging equipment.
[0011] Specifically, the explosion-proof isolation valve adopts the one-way flow principle, which can prevent the flame and shock wave generated by the dust explosion from returning to the production station and causing secondary harm.
[0012] Further in the above description, the explosion-proof dust collector is installed on the interval layer through a support frame, the explosion-proof dust collector consists of a box body, an ash hopper and a filter cartridge arranged in the box body, the ash hopper is installed at the bottom end of the box body, and the end of the ash hopper away from the box body is connected to an explosion-proof ash unloading valve, the box body is installed on the support frame, and the filter cartridge is installed inside the box body through a partition.

[0015] Specifically, when the explosion-proof isolation valve cuts off the dust removal pipe and the dust removal connecting pipe, due to the structural setting of the explosion-proof isolation valve, there must be a gap in the isolation to prevent the dust removal pipe from being over-pressured and causing more serious combustion and explosion. Therefore, the hot and high-temperature gas that passes through the gap will still flow through the dust removal connecting pipe and enter the interior of the explosion-proof dust collector. Therefore, when a high-temperature combustion and explosion phenomenon occurs in the explosion-proof dust collector, the cooling component can quickly cool down the box.
[0016] Further in the above description, the air inlet is opened on one side of the ash hopper, the air outlet is arranged on the top of the box body, the air outlet is connected to the air inlet end of the centrifugal fan, and the air outlet end of the centrifugal fan is exposed to the outside.

[0018] Optionally, in the setting where clean air is directly discharged through a centrifugal fan, the centrifugal fan and the blower can be connected through a circulation duct, so that the filtered clean air passes through the ventilation hood through the ventilation slot, is introduced into the ventilation partition, and enters the workroom through the ventilation hole, thereby improving the internal ventilation efficiency, and the ventilation partition is set to improve the heat dissipation effect of the room body, thereby improving the comfort of the room body.
[0019] Further in the above description, a safety door is provided on the side of the room, and a visual window is provided on the safety door.
[0020] The beneficial effects of the utility model are as follows: through the coordinated use of the dust suction slot and the dust suction hood, the dust generated in the workshop can be effectively sucked into the dust removal pipe, and the dust-containing gas can pass through the pipe into the explosion-proof dust collector for filtration. The clean gas treated by the dust collector is discharged out of the room through the exhaust pipe by the centrifugal fan, thereby ensuring the air circulation and air quality of the workshop, reducing the pollution of the working environment by dust, and protecting the health of the staff. An explosion-proof isolation valve is arranged between the dust removal pipe and the dust removal connecting pipe. When an abnormal situation occurs inside the pipe, such as excessive dust concentration or spark generation, the explosion-proof isolation valve can be quickly closed to cut off the fire source and the circulation of dust, and prevent the occurrence of explosion accidents. The blower can be used to introduce the external cold air from the ventilation pipe into the ventilation interlayer. The ventilation interlayer improves the heat dissipation effect of the side wall of the room body, and the ventilation holes on the ventilation interlayer enable effective air convection to be formed inside the workshop, further reducing the accumulation of dust and reducing the dust concentration, thereby preventing the internal dust concentration from being too high to cause combustion and explosion, and improving the safety and comfort of the working environment inside the room body.
