Description

Technical Field

[0001] The utility model relates to the technical field of graphite processing, in particular to a dust recovery device for producing graphite negative electrode materials. Background Art

[0002] Graphite vacuum cleaners are widely used machines in the graphite processing industry to eliminate graphite dust generated during the processing. Since graphite is a conductive material, once it enters the electrical box, it will cause a short circuit in the electrical components and cause damage to the machine. Therefore, the electrical box must be sealed. Traditional graphite vacuum cleaner electrical boxes mostly use the method of installing sealing strips around the box to seal the electrical box. However, once the electrical box door is opened or the sealing strips are aged and damaged, the external graphite dust will still enter the box through the door or damaged area, causing short circuits and damage to the electrical components.

[0003] Prior art CN206701913U discloses a dust collection device for graphite negative electrode material production equipment, including a dust collection hood arranged on the graphite negative electrode material production equipment, and an air duct connected to the dust collection hood and a fan on the air duct, the other end of the air duct is connected to a trumpet-shaped dust collecting hopper, the end of the dust collecting hopper is connected to a dust collecting bag, a storage tank is provided at the lower end of the dust collecting bag, and the storage tank is connected to the material inlet of the negative electrode material production equipment through a valve. The dust removal equipment is used to absorb the dust generated by the negative electrode material in the production process through the mechanical wind suction of the fan and the addition of the air duct. Through the transformation and addition of devices, this equipment system has achieved dust-free production in the existing production process, a good production environment, and meets the national environmental protection requirements.

[0004] However, when the dust collection device of the above-mentioned graphite negative electrode material production equipment is actually used, the fan works to suck the dust into the dust collection bag for centralized collection. However, when the dust collection bag is subsequently cleaned, the dust is easy to fly around and even inhaled into the body by the cleaning personnel, seriously affecting the work safety of the cleaning personnel.

The above scheme can be used to improve the work safety of cleaning personnel when recycling dust for graphite negative electrode material production. It can be understood that the above scheme can improve the work safety of cleaning personnel when used.

[0022] In this embodiment, the processing box 101 is used for centralized storage and processing of dust gas, and rectangular slide grooves are symmetrically arranged at the bottom of the processing box 101 to facilitate sliding guidance of the rectangular protrusion at the bottom of the receiving box 102 .

[0023] Among them, the receiving box 102 is detachably connected to the processing box 101 and is located at the front side of the processing box 101, the locking pin 103 is slidably connected to the receiving box 102, and is threadedly connected to the processing box 101, and is located on the side of the processing box 101 close to the receiving box 102, the water pipe 104 is fixedly connected to the processing box 101 and is located on the processing box 101, the electric valve 105 is fixedly connected to the water pipe 104 and is located on the water inlet side of the water pipe 104, the atomizing nozzle 106 is threadedly connected to the water pipe 104 and is located at the lower side of the water pipe 104, the exhaust bag 107 is fixedly connected to the processing box 101 and is located at the top of the processing box 101, and the extraction component is arranged on the top of the processing box 101. The top of the receiving box 102 is a sealing part, and the bottom is a receiving chamber. During installation, the rectangular protrusion at the bottom of the receiving box 102 is first matched with the rectangular slide groove at the bottom of the processing box 101 and pushed inward, and then it can be fixed by installing the locking pin 103. The mounting plate of the water guide pipe 104 is installed on the processing box 101 by bolts, and is symmetrically arranged. The electric valve 105 is installed on the water guide pipe 104 by screws and nuts, and its water inlet side is connected to the external water supply pipeline. The water guide pipe 104 is located on the bottom of the inner end of the processing box 101 and has a plurality of threaded mounting holes at intervals, which is convenient for the installation of the atomizing nozzle 106. The exhaust bag 107 is fixed to the air outlet pipe at the top of the processing box 101 by a clamp, which is used for exhausting and preventing internal dust from overflowing. The extraction component is arranged on the top of the processing box 101, and is used to extract and transport the dust generated during the processing of the production equipment into the processing box 101 for collection and treatment.

[0024] Secondly, the one-way valve 108 is fixedly connected to the treatment box 101 and is located at the top of the treatment box 101; the exhaust pipe 109 is threadedly connected to the one-way valve 108 and is located below the atomizing nozzle 106; the power component is arranged at the inlet side of the one-way valve 108. The one-way valve 108 is installed on the treatment box 101 by bolts, and the threaded cavity installed at the bottom of the one-way valve 108 will facilitate the direct installation of the exhaust pipe 109.

At this time, the electric valve 105 is turned on. When the movable valve 105 is in the open state, water is transported into the water pipe 104, and the water is sprayed out through the atomizing nozzle 106. These water mist particles quickly diffuse in the internal air and collide with the dust particles in the air to moisten and condense the dust particles. The wet dust particles gradually increase in size and fall into the receiving box 102 under the action of gravity for collection, thereby achieving a dust removal effect. When the locking pin 103 is removed and the receiving box 102 is taken out for cleaning, the dust will not fly around, thereby improving the work safety of the cleaning personnel when recycling the dust used in the production of graphite negative electrode materials.
