Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a wet explosion-proof dust collector. Background Technique

[0002] Generally, a dust collector consists of a bottom water filtration chamber, a middle metal mesh primary filter element chamber, and an upper high-efficiency filtration chamber to form a filtration system. After dust is inhaled into the equipment, large particles of dust fall into the water to be isolated from the air under the action of gravity, centrifugal force, and the blocking effect of the metal mesh primary filter element. Fine dust will be filtered again by the high-efficiency paper filter element at the top. Over time, a large amount of fine dust adheres to the surface of the paper high-efficiency filter element and is extremely prone to spontaneous combustion when encountering static electricity, sparks, or even friction. Moreover, the explosion-proof fan of such an explosion-proof dust collector is inside the equipment and is in direct contact with metal powder. The fan runs at high speed for a long time and generates heat, further increasing the risk of fire.

[0003] Chinese Patent with the publication number of CN217746384U discloses a wet explosion-proof dust collector for metal dust. It includes a dust suction pipe, a dust collector main body, a bottom water filtration chamber, a primary filter element chamber, a fan, and a high-efficiency filter element chamber. The primary filter element chamber and the bottom water filtration chamber are sequentially arranged inside the dust collector main body from top to bottom; a dust settling space is formed between the primary filter element chamber and the bottom water filtration chamber; a dust removal space is formed between the top of the primary filter element chamber and the inside of the dust collector main body; the dust suction pipe is placed on the side of the dust collector main body and is communicated with the dust settling space; the fan is placed outside the dust collector main body and is communicated with the dust removal space; the high-efficiency filter element chamber is placed outside the dust collector main body and is communicated with the fan. This utility model provides a wet explosion-proof dust collector for metal dust that can greatly reduce the risk of dust spontaneous combustion and can quickly react and automatically extinguish fires.

[0004] For the dust collector involved in the above patent, it achieves the effect of fire and explosion prevention through an explosion-proof fan and an automatic fire extinguishing valve. It conducts explosion-proof treatment on the dust collector through special explosion-proof accessories, resulting in a higher explosion-proof cost and being not easy to conduct explosion-proof protection on the inside of the dust collector. Therefore, we need to propose a wet explosion-proof dust collector. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a wet explosion - proof dust collector, including a dust collector housing 1. Inside the dust collector housing 1, a bottom water filtration chamber 2, a middle - layer metal mesh primary filter element chamber 3, and an upper - layer high - efficiency filtration chamber 4 are sequentially arranged from bottom to top. An air inlet pipe 8 is fixedly installed on the back of the dust collector housing 1. The air inlet pipe 8 is arranged in an L - shape. One end of the air inlet pipe 8 penetrates through the dust collector housing 1 and extends into the inner cavity of the bottom water filtration chamber 2. An exhaust pipe 9 is fixedly installed on the top of the dust collector housing 1.

[0022] In this embodiment, through the setting of the air inlet pipe 8, the air containing dust can be injected into the inner cavity of the dust collector housing 1 through the air inlet pipe 8. At this time, the air sequentially passes through the bottom water filtration chamber 2, the middle - layer metal mesh primary filter element chamber 3, and the upper - layer high - efficiency filtration chamber 4. The dust contained in the air will first be preliminarily filtered by the water in the bottom water filtration chamber 2, and most of the dust can be filtered. The air after filtration still carries a small amount of dust, which will be filtered multiple times through the middle - layer metal mesh primary filter element chamber 3 and the upper - layer high - efficiency filtration chamber 4 to improve the filtration effect.

[0023] Preferably, a dust separation rack 5 is fixedly installed in the inner cavity of the bottom water filtration chamber 2. Baffles 6 are fixedly installed on both sides of the inner cavity of the bottom water filtration chamber 2. An air passage 7 is formed between the baffle 6 and the dust separation rack 5. In this embodiment, after the air enters the bottom water filtration chamber, it will flow through the air passages 7 on both sides of the dust separation rack 5, and the baffle 6 can block the dust carried in the air again, so that the dust falls into the water below, so as to improve the effect of preliminary dust filtration and make as little dust as possible reach the middle metal mesh primary filter element chamber 3 and the upper high-efficiency filtration chamber 4, thereby avoiding the relatively large explosion risk caused by the accumulation of more dust on their surfaces.

[0024] Among them, two groups of support frames 16 are fixedly installed in the inner cavity of the dust collector housing 1, and the bottom of the dust separation rack 5 is attached to the top of the support frame 16. Two groups of positioning frames 17 are fixedly installed in the inner cavity of the dust collector housing 1, and the top of the dust separation rack 5 is fixedly connected to the bottom of the positioning frame 17 by bolts. By using the positioning frame 17 and the support frame 16 in cooperation, the installation stability of the dust separation rack 5 can be improved.

[0025] It is worth noting that a water supply assembly is fixedly installed on one side of the dust collector housing 1 and corresponding to the bottom water filtration chamber 2. The water supply assembly includes a water supply tank 10 fixedly installed on one side of the dust collector housing 1. A water supply pipe 11 is communicated with the back of the water supply tank 10. A communication groove 12 is provided between the water supply tank 10 and the dust collector housing 1. The water supply tank 10 and the bottom water filtration chamber 2 are communicated through the communication groove 12. Through the setting of the water supply assembly, when injecting water into the inside of the bottom water filtration chamber, the user can inject water into the water supply tank 10 through the water supply pipe 11, and the water in the water supply tank 10 can flow into the bottom water filtration chamber 2 through the communication groove 12.

[0026] Furthermore, an installation plate 13 is fixedly installed on the front surface of the dust collector housing 1, and an observation window 14 is embedded on the surface of the installation plate 13. A cleaning door 15 is detachably installed at the bottom of one side of the dust collector housing 1, and the cleaning door 15 is arranged corresponding to the bottom water filtration chamber 2. Through the setting of the installation plate 13, an installation space can be provided for the observation window 14. Through the setting of the observation window 14, it is convenient for the user to see the filtration process in the bottom water filtration chamber 2. When there are too many dust impurities in the water, the user can stop the machine to drain the water and open the cleaning door 15 to clean the dust impurities in the water filtration chamber.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
