Description

Technical Field

[0001] The utility model relates to the technical field of plastic granulation, in particular to an air collecting hood for cable material granulation and cable extrusion waste gas collection, which is used for collecting waste gas generated by a twin-screw or single-screw die head in the process of plastic granulation cable extrusion production. Background Art

[0002] In various cable material manufacturers, engineering plastic manufacturers, cable extrusion manufacturers and other granulation extrusion manufacturers, each must use environmental protection treatment equipment to effectively collect and treat the waste gas VOC generated during the production of granulation extrusion and then eliminate it in compliance with the standards. General environmental protection equipment, such as the treatment process of two-stage activated carbon plus pre-filter, has a high treatment effect, but the effective collection of each waste gas generation point is a long-standing problem. There are many collection processes at present, including range hoods, range hoods plus plastic curtains, range hoods plus small rooms, etc.

[0003] For the oil fume flat-mouth collection hood, there is a distance of about 300mm from the exhaust gas generation point to the collection hood. Since the generated smoke is naturally discharged upwards, when there is side wind during indoor operations, the exhaust gas from the machine head cannot be completely collected by the hood, and the collection rate is only 65%-75%. Therefore, unorganized emissions will occur, causing pollution to the environment.

[0004] The oil fume type air collection hood plus door curtain or oil fume type air collection room covers the entire location where the exhaust gas is generated. Although the collection effect is good, during the production process, due to the production process requirements, the mold, screen, screw, etc. will be changed from time to time, which brings great inconvenience to the operator and greatly reduces the production efficiency. The air collection hood is also not beautiful in the production workshop.

[0005] In view of the above actual situation, there is an urgent need for a gas collecting hood for collecting waste gas generated during the production process of cable material granulation, plastic granulation, and cable extrusion to ensure that the production environment and waste gas emissions meet the standards. Utility Model Content

[0006] In view of the problems existing in the above-mentioned prior art, the utility model provides an air collecting hood for cable material granulation and cable extrusion waste gas collection. Below the original oil fume collecting hood (flat collecting hood), in addition to the three surfaces of the machine head, three blades with a size suitable for the height of the machine head of the on-site production line are added on the left, right and front sides. A hinge is welded at the connection with the original flat collecting hood, and then a magnet is welded at the overlapping part where the newly added blades are folded upward. When the newly added blades below are flipped up, they are attracted by the magnet to form a flat collecting hood. When the three blades on the left, right and front sides are put down, it is a very closed collecting hood, and the collection effect is equivalent to that of an air collecting room.

[0007] The utility model adopts the following technical solutions:

[0008] A gas collecting hood for collecting waste gas from cable material granulation and cable extrusion, comprising a gas collecting hood body, blades, folding hinges, strong magnets and a waste gas collection outlet, wherein the blades are arranged directly below the gas collecting hood body and form a foldable structure with the side walls of the gas collecting hood body through the folding hinges; the strong magnets are arranged on the side walls of the gas collecting hood body so that the blades can be attracted by the strong magnets when they are flipped up along the folding hinges; the waste gas collection outlet is located at the top of the gas collecting hood body.

[0009] There are three blades, namely blade A, blade B and blade C, wherein blade A is located below the left side wall of the air collecting hood body, blade B is located below the front side wall of the air collecting hood body, and blade C is located below the right side wall of the air collecting hood body.

[0010] The width of the blade is consistent with the width of the side wall of the corresponding air collecting hood body.

[0011] The blade is an anti-corrosion iron sheet structure or a stainless steel sheet structure; when the blade is a stainless steel sheet structure, a ferromagnetic material needs to be provided at a position on the outer wall of the blade corresponding to the strong magnet provided on the wall of the air collecting hood body.

[0012] The technical solution of the utility model has the following advantages:

[0013] The utility model can collect waste gas generated in the production process of cable material granulation and the head of the cable extrusion equipment, with an efficiency of more than 95%. It has the advantages of beautiful appearance, simple operation, and no extra space occupation, and significantly improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 As shown, the utility model provides a gas collecting hood for collecting waste gas from cable material granulation and cable extrusion, comprising a gas collecting hood body 1, blades 2, folding hinges 3, strong magnets 4 and waste gas collection outlets 5. The blades 2 are arranged directly below the gas collecting hood body 1, and form a foldable structure with the side wall of the gas collecting hood body 1 through the folding hinges 3. Strong magnets 4 are arranged on the side wall of the gas collecting hood body 1, so that the blades 2 can be attracted by the strong magnets 4 when they are turned up along the folding hinges 3. The waste gas collection outlet 5 is located at the top of the gas collecting hood body 1, and is used to guide the collected waste gas to environmental protection treatment equipment.

[0020] Furthermore, the blade 2 is composed of three blades, namely blade A21, blade B22 and blade C23, wherein blade A21 is located below the left side wall of the hood body 1, blade B22 is located below the positive side wall of the hood body 1, and blade C23 is located below the right side wall of the hood body 1. The width of the blade 2 is consistent with the width of the side wall of the hood body 1 corresponding to it.

[0021] The blade 2 is made of an anti-corrosion iron sheet (such as a galvanized iron sheet) or a stainless steel sheet. When the blade 2 is made of a stainless steel sheet, a ferromagnetic material needs to be provided at a position on the outer wall of the blade 2 corresponding to the strong magnet 4 provided on the side wall of the gas collecting cover body 1.

[0022] Before the equipment is put into production, the three blades 2 are folded upwards and aligned with the center of the twin-screw extruder head; when the production equipment starts to extrude materials and generate waste gas, the left blade A21, the front blade B22 and the right blade C23 can be manually lowered to a horizontal position along the folding hinge 3 to completely cover and seal the twin-screw extruder head, thereby effectively collecting the waste gas generated during the production process, and all of it is sucked out through the negative pressure exhaust of the environmental protection equipment and treated to meet the emission standards, so that the effective collection rate is more than 95%. When it is necessary to replace the mold, replace the filter, and remove the screw for cleaning, the operator will flip the three blades 2 up to the folded state again through the folding hinge 3, and fix them through the strong magnet 4. The blades 2 are firmly attracted by the strong magnet, and there is enough space below to change the mold, change the filter, disassemble and install the screw, etc.

[0023] The utility model can collect waste gas generated in the production process of cable material granulation and the head of the cable extrusion equipment, with an efficiency of more than 95%. It has the advantages of beautiful appearance, simple operation, and no extra space occupation, and significantly improves production efficiency.
