Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to an injection molding waste gas adsorption and cleaning device. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity. The injection molding machine will produce organic waste gas during the heating process, including hot dust particles, styrene, toluene, etc. Since these harmful gases are polluting, directly discharging them into the air will not only cause physical harm to the workers, but also pollute the environment.

[0003] Traditional exhaust gas treatment devices directly treat hot exhaust gas, which seriously affects the service life of the purification layer. In addition, simply using activated carbon to adsorb harmful substances in the exhaust gas is not only not ideal, but the dust and particulate matter mixed in the exhaust gas will cause the activated carbon to quickly become blocked and ineffective.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an injection molding waste gas adsorption and cleaning device is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide an injection molding waste gas adsorption and cleaning device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an injection molding waste gas adsorption and cleaning device, comprising a cylinder and a spray dust removal assembly, a spray dust removal assembly is arranged at the bottom end of the cylinder, the spray dust removal assembly comprises a sedimentation tank, a slag discharge pipe, a circulation pipe, a filter screen, a water pump and a spray pipe, one side of the sedimentation tank is connected to the slag discharge pipe, and the other side of the sedimentation tank is connected to the circulation pipe, a filter screen is arranged at the inlet of the circulation pipe, and the middle part of the circulation pipe is connected to the water pump, the outlet of the circulation pipe is connected to the spray pipe, and the spray pipe is fixed to the middle part of the inner wall of the cylinder.

[0007] Furthermore, the water pump input end is connected to the sedimentation tank through the circulation pipe inlet, and the water pump output end is connected to the spray pipe through the circulation pipe outlet.

[0008] Furthermore, three air inlets are distributed in an array on the top of the cylinder, and threaded joints are provided at the openings of the air inlets.

[0009] Furthermore, a photocatalytic component is fixed to the side of the cylinder, and the photocatalytic component includes a shell, an exhaust pipe and a waterproof cover. The bottom of the shell is connected to the exhaust pipe, and a waterproof cover is arranged above the connection between the exhaust pipe and the cylinder.

[0010] Furthermore, the photo-oxidation catalytic component also includes activated carbon limiting filter cotton, UV ultraviolet lamp tube and honeycomb catalytic plate. The activated carbon limiting filter cotton is inserted into the bottom end of the shell, and the UV ultraviolet lamp tube is arranged in an array at the top end of the shell, and a honeycomb catalytic plate is arranged between the UV ultraviolet lamp tube array.

[0011] Furthermore, the top of the shell is connected to a bracket, and an air outlet is opened on the side of the bracket.

[0012] Furthermore, a motor is fixed on the top of the bracket, and a centrifugal impeller is fixed on the output end of the motor.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When the utility model is in use, a corrugated suction head is connected to the outside of the corresponding threaded joint according to needs, and the idle air inlet is blocked with a rubber plug. Then, the motor is activated to drive the centrifugal impeller inside the bracket to rotate, so that negative pressure is generated in the cylinder, and the waste gas generated when the injection molding material is taken out is sucked into the cylinder. On the one hand, the input end of the water pump is connected to the sedimentation tank through the inlet of the circulation pipe, and on the other hand, the output end of the water pump is connected to the spray pipe through the outlet of the circulation pipe. The liquid mixed with the chemical absorbent in the sedimentation tank is combined with the waste gas by atomization, which is used to clean the waste gas and remove a large amount of dust, while reducing the temperature of the waste gas and improving the subsequent treatment efficiency.

[0015] 2. When the utility model is in use, the waste gas with reduced temperature enters the photocatalytic component through the exhaust pipe. The waterproof cover above the connection between the exhaust pipe and the cylinder is used to prevent the spray water from being sucked into the shell. By arranging activated carbon limiting filter cotton, UV ultraviolet lamp and honeycomb catalytic plate in the shell in sequence, the waste gas molecular chain is interrupted by UV light irradiation, so that the waste gas is cracked and differentiated. At the same time, the strong oxidizing property of the honeycomb catalytic plate further oxidizes and decomposes the waste gas molecules, so as to achieve harmless treatment of injection molding waste gas and discharge it from the air outlet.
