Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, and more specifically, to a blow molding organic waste gas treatment device. Background Technology
[0002] Blow molding is an important manufacturing process for plastic products. In the blow molding process, plastic is melted and extruded to form a tube. Then, one end of the tube is clamped by a mold, and the other end is fused to form the bottle bottom. Pressurized air is blown in to solidify the plastic and form the bottle. The blow molding process generates organic waste gas, which must be treated before it can be discharged.
[0003] A search revealed a Chinese patent publication (CN 216171323 U) that discloses an organic waste gas treatment device. While this device allows for separation of the connecting frame from the filter box by pulling it, facilitating the replacement of the saturated activated carbon screen and improving its purification effect, the need to stop the device during activated carbon screen replacement causes delays, impacting the bottle blowing organic waste gas treatment process and reducing efficiency. Therefore, this invention designs a bottle blowing organic waste gas treatment device to address these issues. Utility Model Content
[0004] The purpose of this invention is to provide a device for treating organic waste gas from blow molding, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A device for treating organic waste gas from bottle blowing includes a base frame, an inlet pipe, and an activated carbon mesh. An absorption tower is installed at the front end of the base frame, and a filter box is installed at the rear end. A partition is fixedly installed inside the filter box, dividing the interior into an upper cavity and a lower cavity from top to bottom. An air intake pipe I is fixedly connected to the upper cavity and the inlet pipe, and an air intake pipe II is fixedly connected to the lower cavity and the inlet pipe. Several filter elements slide through the sides of both the upper and lower cavities at intervals. The filter box and the filter frame are threaded together by a T-shaped stud. The filter frame is fixedly sleeved on the outside of the activated carbon mesh. A heating chamber is provided between the absorption tower and the filter box. An electric heater is fixedly installed in the heating chamber. A vent pipe I is fixedly connected between the upper cavity and the heating chamber. A vent pipe II is fixedly connected between the lower cavity and the heating chamber. Solenoid valves are provided on the vent pipe I, vent pipe II, and vent pipe II. A guide pipe is fixedly connected between the absorption tower and the heating chamber.
[0007] As a preferred embodiment of this utility model, a control panel is fixedly installed on the end face of the filter box, and the output end of the control panel is electrically connected to the input end of the solenoid valve and the electric heater.
[0008] As a preferred embodiment of this utility model, the filter box has a groove on its side and the filter frame has a sealing protrusion on its inner side, the sealing protrusion being adapted to the groove.
[0009] As a preferred embodiment of this utility model, an inlet pipe is fixedly connected to the top side of the absorption tower, one end of the inlet pipe is fixedly connected to a nozzle, an exhaust pipe is fixedly connected to the upper end of the base frame, an outlet pipe is fixedly connected to the bottom end of the absorption tower, and a packing layer is provided inside the absorption tower between the nozzle and the inlet pipe.
[0010] As a preferred embodiment of this utility model, a handle is fixedly connected to the outer side of the filter frame, and the cross-sectional shape of the handle is U-shaped.
[0011] As a preferred embodiment of this utility model, the outer fixed sleeve of the air guide tube is provided with a heat insulation sleeve.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] In the initial state of use, the solenoid valves on the air intake pipe I and the ventilation pipe I are open, while the solenoid valves on the air intake pipe II and the ventilation pipe II are closed. If it is necessary to replace the saturated activated carbon screen in the upper chamber, the solenoid valves on the air intake pipe I and the ventilation pipe I are closed, while the solenoid valves on the air intake pipe II and the ventilation pipe II are opened. The organic waste gas generated during the blow molding process is then introduced into the lower chamber through the air intake pipe and the air intake pipe II. The activated carbon screen in the lower chamber continues to purify the organic waste gas. The waste gas is then introduced into the heating chamber through the ventilation pipe II. The T-shaped stud is loosened, and the filter frame is slid outwards along the side of the upper chamber for replacement. If it is necessary to replace the saturated activated carbon screen in the lower chamber later, the process can be switched back to the initial state described above. Therefore, replacing the activated carbon screen does not require stopping the operation, effectively avoiding delays and ensuring the smooth progress of the blow molding organic waste gas treatment process, thus improving the efficiency of organic waste gas treatment.

The filter frames 5 are fixedly sleeved on the outside of the activated carbon mesh 6. A heating chamber 8 is provided between the absorption tower 2 and the filter box 3. An electric heater 801 is fixedly installed in the heating chamber 8. A vent pipe I306 is fixedly connected between the upper cavity 302 and the heating chamber 8. A vent pipe II307 is fixedly connected between the lower cavity 303 and the heating chamber 8.

A guide pipe 201 is fixedly connected between the absorption tower 2 and the heating chamber 8.
[0021] Among them, such as Figure 1As shown, a control panel 9 is fixedly installed on the end face of the filter box 3.

[0022] Among them, such as Figure 3 and Figure 4 As shown, a groove 308 is provided on the side of the filter box 3, and a sealing protrusion 502 is provided on the inner side of the filter frame 5. The sealing protrusion 502 is adapted to the groove 308, so that the sealing protrusion 502 can be fitted into the groove 308 to ensure the sealing effect between the filter box 3 and the filter frame 5.
[0023] Among them, such as Figure 2 As shown, an inlet pipe 202 is fixedly connected to the top side of the absorption tower 2, and a nozzle 2021 is fixedly connected to one end of the inlet pipe 202.

[0026] The working principle of this utility model:
[0027] During operation, the initial state is that the solenoid valves 7 on the air intake pipe I304 and the ventilation pipe I306 are open, and the solenoid valves 7 on the air intake pipe II305 and the ventilation pipe II307 are closed. The organic waste gas generated during the blow molding process is introduced into the upper cavity 302 through the air inlet pipe 4 and the air intake pipe I304. The activated carbon mesh 6 inside the upper cavity 302 purifies the organic waste gas. The waste gas then enters the heating chamber 8 through the ventilation pipe I306, where the electric heater 801 heats the passing waste gas. The waste gas then enters the absorption tower 2 through the air guide pipe 201. The absorbent liquid enters the nozzle 2021 through the liquid inlet pipe 202, and the nozzle 2021 sprays the absorbent liquid onto the packing layer 205. The waste gas and absorbent liquid contact each other in the gaps of the packing layer 205, and the absorbent liquid absorbs the organic matter in the waste gas. The absorbent liquid is finally discharged through the liquid outlet pipe 204, and the purified waste gas is discharged through the exhaust pipe 203. If necessary... When replacing the saturated activated carbon mesh 6 in the upper cavity 302, close the solenoid valves 7 on the air intake pipe I304 and the ventilation pipe I306, and open the solenoid valves 7 on the air intake pipe II305 and the ventilation pipe II307. The organic waste gas generated during the blow molding process is then introduced into the lower cavity 303 through the air intake pipe 4 and the air intake pipe II305. The activated carbon mesh 6 in the lower cavity 303 continues to purify the organic waste gas. The waste gas is then introduced into the heating chamber 8 through the ventilation pipe II307. Loosen the T-shaped stud 501 and use the handle 503 to pull the filter frame 5 outwards along the side of the upper cavity 302 for replacement. If the saturated activated carbon mesh 6 in the lower cavity 303 needs to be replaced later, simply switch back to the initial state described above for replacement. This eliminates the need to stop operation when replacing the activated carbon mesh 6, effectively avoiding delays and ensuring a smoother blow molding process for treating organic waste gas.
