Description

Technical Field

[0001] The utility model relates to the technical field of polypropylene production, in particular to a smoke adsorption device used for polypropylene cooling. Background Art

[0002] In the production of engineering plastic modification, the material strips extruded from the extruder head after high-temperature melting in the plastic extruder need to be cooled before entering the pelletizing system for pelletizing. This cooling process is the process of the material strips passing through the water tank.

[0003] The cooling process of the material strip from the extruder to the water tank will release a lot of heat, and a lot of smoke and dust will be generated in the area where the material strip and water contact. Usually, a vacuum cleaner is set up to absorb and reduce smoke and dust. However, the existing vacuum cleaner has poor absorption effect, and some of the scattered smoke and dust will pollute the internal environment of the factory, and long-term inhalation of operators will cause health damage. In addition, the water cooling process of the material strip consumes a lot of water resources. The material strip is air-cooled before water cooling. How to use the vacuum cleaner to achieve a multi-functional effect is an urgent problem to be solved. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a smoke adsorption device for polypropylene cooling.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A smoke adsorption device for polypropylene cooling comprises a dust suction mechanism arranged between an extruder and a cooling water trough, the dust suction mechanism comprises a dust collector and a dust suction hood plate connected to the dust collector, a front baffle plate and side baffle plates which can be adjusted vertically are arranged on the front and both sides of the dust suction hood plate, a groove plate is detachably arranged below the dust suction hood plate, the groove plate forms a guide air chamber with the inner cavity of the dust suction hood plate between the extruder and the cooling water trough, and a folded smoke pipe and a ventilation pipe are arranged on the top of the dust suction hood plate.

[0007] Furthermore, the four ends of the dust hood plate are vertically provided with slide grooves, and the front baffle plate and the side baffle plate are adapted to be slidably connected with the slide grooves. According to the height of the dust hood plate from the cooling water tank, the front baffle plate and the side baffle plate are adjusted to cover the bottom of the dust hood plate respectively. Since the back of the dust hood plate is close to the extruder, it is only necessary to cover the junction between the dust hood plate and the cooling water tank.

[0008] Furthermore, a locking assembly for fixing the front baffle or the side baffle is provided at the bottom of the slideway. The locking assembly can be a tightening bolt or a lock buckle. After the height of the front baffle and the side baffle is adjusted, the height is fixed by the locking assembly.

[0009] Furthermore, the slot plate is a U-shaped structure, and a water storage space is formed around the slot plate. After the material strip is led out of the extruder and before entering the cooling water tank, an unobstructed space is formed below the material strip, which is covered and closed by the slot plate, so that a relatively closed environment can be formed below the dust cover plate, and the gas flow is introduced by the ventilation pipe and led out at the folded smoke pipe to form a gas flow. Water is poured into the slot plate to prevent the falling debris from scalding the slot plate.

[0010] Furthermore, the side baffles are provided with mounting holes, and the two ends of the slot plate are provided with mounting openings adapted to the mounting holes. After the position adjustment and installation of the dust hood plate are completed, the height of the front baffle and the side baffles are adjusted. Then, the two ends of the detachable slot plate are installed on the two side baffles and fixed through the mounting holes.

[0011] Furthermore, the four ends of the dust hood plate are provided with mounting rods extending vertically upwards. The mounting rods are used to be fixed on the top of the factory building and other steel structure materials to complete the construction of the dust hood plate.

[0012] Furthermore, the dust collecting hood plate is connected to the vacuum cleaner through a foldable smoke pipe. The vacuum cleaner generates an adsorption airflow below the dust collecting hood plate through negative pressure suction, thereby guiding the smoke and dust into the foldable smoke pipe.

[0013] Furthermore, a smoke filter is arranged on the ventilation pipe, which can filter the external floating particulate impurities and suspended matter to prevent them from being introduced into the vacuum cleaner through the airflow, and also prevent them from adhering to the material strips.

[0014] Furthermore, the width of the slot plate is less than or equal to the distance between the extruder and the cooling water tank. After the side baffles are arranged, there is an area between the extruder and the cooling water tank that cannot be blocked by the side baffles, and there is still space under the material strip that is connected to the outside world. By setting the slot plate, the above area can be covered to form a relatively closed chamber.

[0015] Furthermore, the height of the front baffle and the side baffle is not less than the distance between the dust collecting cover plate and the cooling water tank. By adjusting the height of the front baffle and the side baffle, the smoke generating area can be covered.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The utility model has a better covering effect, reducing the smoke and dust from escaping into the factory and affecting the health of workers who work for a long time;

[0018] 2. In the process of absorbing smoke and dust by the vacuum cleaner, the utility model guides the gas to the outlet end of the extruder through the guide mechanism, and the high-temperature material strips are air-cooled to reduce the initial temperature of the material strips;

[0019] 3. The utility model uses air cooling before water cooling, which can reduce the water consumption and replacement frequency of water cooling, thereby achieving the purpose of energy saving and efficiency improvement. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0025] Embodiment 1, as Figure 1 , 2 As shown in Figure 3, the utility model discloses a smoke adsorption device for polypropylene cooling, including a dust suction mechanism arranged between an extruder 1 and a cooling water trough 2, wherein the dust suction mechanism includes a dust collector and a dust suction hood plate 3 connected to the dust collector, and the front and both sides of the dust suction hood plate 3 are respectively arranged with a vertically adjustable front baffle 4 and a side baffle 5, and a groove plate 6 is detachably arranged below the dust suction hood plate 3, and the groove plate 6 forms a guide air chamber with the inner cavity of the dust suction hood plate 3 between the extruder 1 and the cooling water trough 2, and the top of the dust suction hood plate 3 is provided with a folded smoke pipe 7 and a ventilation pipe 8.

[0026] The four ends of the dust hood plate 3 are vertically provided with slide grooves 9, and the front baffle plate 4 and the side baffle plate 5 are adapted to be slidably connected with the slide grooves 9. Specifically, according to the height of the dust hood plate 3 from the cooling water tank 2, the front baffle plate 4 and the side baffle plate 5 are adjusted to cover the bottom of the dust hood plate 3 respectively. Since the back of the dust hood plate 3 is close to the extruder 1, it is only necessary to cover the junction between the dust hood plate 3 and the cooling water tank 2. When a large amount of smoke and dust is generated when the material strip contacts water, most of the smoke and dust will be absorbed into the vacuum cleaner to reduce the smoke and dust from escaping outward.

[0027] The bottom of the chute 9 is provided with a locking assembly for fixing the front baffle 4 or the side baffle 5. Specifically, the locking assembly can be a tightening bolt or a lock buckle, and after adjusting the height of the front baffle 4 and the side baffle 5, the height is fixed by the locking assembly.

[0028] The slot plate 6 is a U-shaped structure, and a water storage space is formed around the slot plate 6. Specifically, after the material strip is exported from the extruder 1 and before entering the cooling water tank 2, an unobstructed space is formed below the material strip, which is covered and closed by the slot plate 6, so that a relatively closed environment can be formed below the dust cover plate 3, and the gas flow is introduced by the ventilation pipe 8 and exported at the folded smoke pipe 7 to form a gas flow. When the material strip comes out of the extruder, the temperature is very high. If high-temperature fragments fall, it will damage the slot plate 6. Therefore, water is poured into the slot plate 6 to prevent the falling fragments from scalding the slot plate 6.

[0029] The side baffles 5 are provided with mounting holes 10, and both ends of the slot plate 6 are provided with mounting openings 11 adapted to the mounting holes 10. Specifically, after the position adjustment and installation of the dust hood plate 3 are completed, the heights of the front baffle 4 and the side baffles 5 are adjusted. Then, the two ends of the detachable slot plate 6 are installed on the two side baffles 5 and fixed through the mounting holes 10.

[0030] The four ends of the dust hood plate 3 are provided with mounting rods 12 extending vertically upward. Specifically, the mounting rods 12 are used to be fixed on the top configuration of the factory building and other steel structure materials to complete the construction operation of the dust hood plate 3.

[0031] The dust collecting hood plate 3 is connected to the vacuum cleaner through the folding smoke tube 7. Specifically, the vacuum cleaner generates an adsorption airflow below the dust collecting hood plate 3 through negative pressure suction, thereby introducing smoke and dust into the folding smoke tube 7.

[0032] The ventilation pipe 8 is provided with a smoke filter 13. Specifically, the smoke filter 13 can filter the external floating particulate impurities and suspended matter to prevent them from being introduced into the vacuum cleaner through the airflow, and also prevent them from adhering to the material strip. In addition, a partition is inserted between the ventilation pipe 8 and the folded smoke pipe 7, and the partition extends downward to the material strip, which can ensure that the airflow is generated at the material strip, thereby achieving an air cooling effect.

[0033] The width of the slot plate 6 is less than or equal to the distance between the extruder 1 and the cooling water tank 2. Specifically, after the side baffles 5 are arranged, there is an area between the extruder 1 and the cooling water tank 2 that cannot be blocked by the side baffles 5, and there is still space under the material strip that is connected to the outside. By setting the slot plate 6, the above area can be covered to form a relatively closed chamber.

[0034] The height of the front baffle plate 4 and the side baffle plate 5 is not less than the distance between the dust collecting cover plate 3 and the cooling water tank 2. Specifically, by adjusting the height of the front baffle plate 4 and the side baffle plate 5, the smoke generating area is covered.

[0035] Embodiment 2: Based on Embodiment 1, this embodiment proposes a specific working principle of a smoke adsorption device for polypropylene cooling.

[0036] The specific implementation principle process is as follows:

[0037] First, the extruder 1 extrude the polypropylene material and form the desired finished product. During this process, smoke and particulate matter will be generated and released into the surrounding environment along with the airflow. The dust collection mechanism is located between the extruder 1 and the cooling water tank 2. By using the negative pressure principle, the smoke is guided into the bottom of the dust collection hood plate 3 through the adsorption airflow generated by the vacuum cleaner. The front and both sides of the dust collection hood plate 3 are equipped with vertically adjustable baffles to ensure that the area where smoke is generated is covered to prevent smoke from escaping.

[0038] The function of the slot plate 6 is to form a guide air chamber, which closes the inner cavity of the dust cover plate 3 and forms a water storage space inside it. This water storage space can not only prevent high-temperature debris from falling and damaging the slot plate 6, but also provide a relatively closed environment, making it easier for smoke to be adsorbed and filtered. The folding smoke pipe 7 connects the dust cover plate 3 and the vacuum cleaner to guide the adsorbed smoke into the vacuum cleaner. A smoke filter 13 is arranged on the ventilation pipe 8 to filter external particulate impurities and suspended matter to prevent them from entering the vacuum cleaner or adhering to the product. Finally, by adjusting the height of the baffle and installing the slot plate 6, ensure that the dust cover plate 3 covers the area where smoke is generated and forms a relatively closed chamber. When the vacuum cleaner is working, a negative pressure suction force will be generated. If the bottom of the dust cover plate 3 is not blocked, the smoke will be directly sucked into the vacuum cleaner, but an airflow cannot be generated. The lower part of the dust collecting hood plate 3 is shielded and only the ventilation pipe 8 is retained. By reducing the air inlet, a relatively large airflow can be generated. In the process of absorbing smoke and dust, the material strips are initially cooled by the air-cooling airflow to reduce the initial temperature of the material strips.

[0039] Of course, the present invention may have many other implementation modes. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
