Description

Technical Field

[0001] This utility model relates to the field of spray painting exhaust gas treatment technology, and more specifically, to a combined structure spray painting exhaust gas collection device. Background Technology

[0002] In painting operations such as machining or furniture manufacturing, waste gas containing harmful substances such as paint mist and organic solvents is generated. In order to protect the environment and the health of operators, these waste gases usually need to be collected and purified. Existing painting waste gas collection devices usually include a collection hood and a waste gas treatment unit connected to the rear end. The waste gas treatment unit is equipped with a purification device, such as an activated carbon adsorption box or a spray tower, in which the waste gas is drawn in and purified.

[0003] However, the processing capacity and volume of these purification devices are limited. For example, activated carbon will reach adsorption saturation after a period of use and needs to be replaced or regenerated; the washing liquid in the spray tower also needs to be replaced regularly to ensure the purification effect. When the purification device reaches its processing limit or needs maintenance (such as replacing filter media or cleaning residues), the entire exhaust gas treatment system must be shut down. This means that the front-end spraying production line must also be interrupted to wait for the exhaust gas treatment unit to resume normal operation. This frequent shutdown not only seriously affects the continuity of production and overall efficiency, but also increases unnecessary time and labor costs, becoming a bottleneck restricting the automation and efficiency development of the spraying industry.

[0004] Therefore, this utility model proposes a combined structure spraying exhaust gas collection device to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the spraying exhaust gas collection device, such as the limited purification capacity of a single gas storage chamber, which requires the equipment to stop the front-end exhaust gas collection work during the purification or cleaning process, resulting in production interruption, low work efficiency, and cumbersome and laborious cleaning process of the gas storage chamber, this utility model aims to provide a spraying exhaust gas collection device with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a combined structure spraying exhaust gas collection device, including: a base plate, at least two gas storage chambers disposed on the base plate, and a diversion mechanism; the diversion mechanism includes a diversion chamber, a flow control plate disposed inside the diversion chamber, and a motor for driving the flow control plate to rotate.

[0007] The diversion chamber has an exhaust gas inlet and two outlets respectively connected to the at least two gas storage chambers.

[0008] Furthermore, the motor is connected to the flow control plate, and by driving the flow control plate to rotate inside the flow distribution chamber, it can selectively close the outlet to one of the gas storage chambers and simultaneously open the outlet to the other gas storage chamber.

[0009] Preferably, the diversion mechanism further includes a fan, a fan hood, and a hose connecting the fan hood and the diversion chamber located upstream of the exhaust gas inlet of the diversion chamber.

[0010] Preferably, the diversion mechanism further includes a guide pipe connected between the outlet of the diversion chamber and the gas storage chamber.

[0011] Preferably, the diversion mechanism further includes a gas flow warning light, which is disposed on the guide tube and electrically connected to the control circuit of the motor.

[0012] Preferably, the diversion mechanism is supported on the base plate by a support rod.

[0013] Preferably, the spraying exhaust gas collection device of this combined structure also includes a cleaning mechanism for cleaning the gas storage tank.

[0014] In one specific implementation, the cleaning mechanism includes a cover plate that is detachably sealed to the top of the gas storage chamber, a water pipe interface on the cover plate, and a water spray hole on the bottom surface of the cover plate that communicates with the water pipe interface.

[0015] Furthermore, the cleaning mechanism also includes a wastewater recovery tank and a second motor, which drives a pump located in the wastewater recovery tank to pump the sewage from the bottom of the gas storage chamber into the wastewater recovery tank.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting up a diversion mechanism with a rotatable flow control plate, realizes the intelligent switching of waste gas between at least two gas storage chambers, which solves the problem of production interruption caused by the limited processing capacity of a single gas storage chamber in the prior art. It achieves the technical effect of uninterrupted collection of waste gas, and significantly improves the efficiency of equipment use and the continuity of production.

[0017] 2. This utility model solves the problems of low efficiency and incomplete cleaning of gas storage tanks in the prior art by integrating a cleaning mechanism with a cover plate spray hole, a wastewater recycling tank and a motor. It achieves the technical effect of automatically cleaning the residue inside the gas storage tank and recycling wastewater, which not only improves cleaning efficiency and shortens equipment standby time, but also reduces the safety risks of manual operation.

[0018] 3. This utility model solves the problem of fixed air inlet position and limited application range of the existing collection device by setting a wind hood and adjustable hose at the front end of the exhaust gas collection. It achieves the technical effect of flexibly adjusting the collection position and angle according to the actual working conditions, which greatly enhances the applicability and ease of operation of the device.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example Please refer to Figures 1 to 4 This utility model provides a combined structure spraying exhaust gas collection device, which aims to solve the problem in the prior art that the exhaust gas collection equipment needs to be shut down due to the limited purification speed of the gas storage chamber 301.

[0023] like Figure 1As shown, the combined structure of the spraying exhaust gas collection device includes a base plate 1, a diversion mechanism 2, at least two gas storage chambers 301, and a cleaning mechanism 3, all mounted on the base plate 1. The base plate 1 provides an installation platform for the entire device. The diversion mechanism 2 is used to guide the collected exhaust gas into different gas storage chambers 301. The gas storage chambers 301 are used to temporarily store the exhaust gas for later treatment, while the cleaning mechanism 3 is used to clean the interior of the gas storage chambers 301 after the exhaust gas is treated.

[0024] To solve the above-mentioned technical problems, the technical solution of this embodiment lies in the specific structural cooperation and connection relationship inside the diversion mechanism 2.

[0025] Please refer to the following carefully. Figures 1 to 3 The structure will be described in detail below: The diversion mechanism 2 is fixedly connected to the top of the base plate 1 via a support rod 4. The diversion mechanism 2 includes a fan 208, with a fan shroud 207 fixedly connected to the inlet end of the fan 208. The outlet end of the fan 208 is flexibly connected to the exhaust gas inlet of the diversion chamber 201 via a flexible hose 206. The diversion chamber 201 has two exhaust gas outlets. A flow control plate 202 is rotatably connected inside the diversion chamber 201. A motor 204 is fixedly installed on the outer wall of the diversion chamber 201. The output shaft of the motor 204 passes through the chamber wall of the diversion chamber 201 and is fixedly connected to the flow control plate 202. The two exhaust gas outlets of 201 are fixedly connected to the top air inlets of the two gas storage chambers 301 through guide pipes 205. A gas flow warning light 203 is installed on the guide pipe 205. The gas flow warning light 203 is electrically connected to the control circuit of motor 204. This structure, in which the flow control plate 202 is driven by motor 204 to rotate inside the diversion chamber 201, can change the channel of exhaust gas flow, allowing it to switch between the two guide pipes 205, thereby selectively flowing into different gas storage chambers 301, ensuring the continuity of exhaust gas collection.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, to achieve automatic cleaning of the gas storage chamber 301, the device further includes a cleaning mechanism 3, please refer to... Figure 4The cleaning mechanism 3 includes a cover plate 302 that is detachably sealed to the top of the gas storage chamber 301. The top of the cover plate 302 is provided with a water pipe interface 303 for connecting to an external water source. The bottom surface of the cover plate 302 is provided with multiple water spray holes 304. These water spray holes 304 and the water pipe interface 303 are interconnected through the flow channel inside the cover plate 302. As a further improvement to the cleaning function, the cleaning mechanism 3 also includes a wastewater recovery tank 305 and a second motor 306 that drives it. The wastewater recovery tank 305 is set on the base plate 1. The second motor 306 is fixed to the wastewater recovery tank 305 and is used to drive the water pump inside the wastewater recovery tank 305. The suction port of the water pump is connected to the bottom of the gas storage chamber 301 through a pipe.

[0027] Working principle: When exhaust gas collection is required, the diversion mechanism 2 can be used to align the fan 208 with the area to be collected. The fan 208 will draw in the exhaust gas, and the hood 207 will prevent the collected gas from escaping. The hose 206 can be adjusted in angle and length at any time to cope with different environments. When the gas flows along the guide pipe 205 and passes through the area where the warning light 203 is located, the warning light 203 will detect the beginning and end of the gas flow and transmit a signal to the drive motor 204 to prevent it from easily changing direction. When one of the gas storage chambers 301... When full, because motor 204 is fixedly connected to flow control plate 202, motor 204 can drive flow control plate 202 inside flow distribution chamber 201, causing it to turn inside flow distribution chamber 201, and then flow into guide pipe 205 at the other end. Finally, it enters another gas storage chamber 301 for processing through guide pipe 205, achieving non-stop operation. The support rod 4 at the top of the base plate 1 can support the entire flow distribution mechanism 2, solving the problem in the prior art that the gas storage chamber 301 has limited gas purification speed, causing equipment shutdown during waste gas treatment. After the exhaust gas treatment is completed, the cleaning mechanism 3 can be used. The water pipe is connected to the water pipe interface 303 on the top of the cover plate 302. The cover plate 302 seals the gas storage chamber 301. After the water valve is started, the water spray hole 304 at the bottom of the cover plate 302 can clean the inner wall of the gas storage chamber 301. The treated residue inside the gas storage chamber 301 is collected at the bottom of the gas storage chamber 301. Then the motor 306 is started, and the wastewater recovery tank 305 will draw the sewage inside the gas storage chamber 301 and collect it inside itself. Finally, it is discharged through the drain outlet. The base plate 1 provides an operating platform for the entire cleaning mechanism 3, which can effectively clean the residue after exhaust gas treatment and speed up the treatment process.
