Description

Technical Field

[0001] This utility model is a waste gas collection device for a stirred tank, belonging to the field of stirred tank technology. Background Technology

[0002] When producing UV-curable coatings, a mixing tank is required for processing. The mixing tank can promote mixing and chemical reactions, and can effectively mix solid materials with liquid materials evenly. During the use of the mixing tank, a large amount of waste gas is generated, which needs to be collected by a collection device.

[0003] While existing waste gas collection devices can collect and transport waste gas through collection hoods, they are not effective in preventing backflow during normal gas transport and have low initial filtration and purification effects on the gas entering the collection device, thus reducing the efficiency of the collection device in treating waste gas. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a stirred tank exhaust gas collection device to solve the problems mentioned in the background art, such as poor anti-backflow effect for normal gas transportation and low preliminary filtration and purification effect for gas input into the collection device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stirred tank exhaust gas collection device, comprising a stirred tank body, an exhaust pipe at the top of the stirred tank body, a connecting cylinder threaded to the inner wall of the exhaust pipe, a first external spiral on the outer wall of the connecting cylinder, a second internal spiral at the connection between the inner wall of the exhaust pipe and the first external spiral, a flow port at one end of the connecting cylinder, a grid block fixedly connected to the other end of the connecting cylinder, a telescopic rod fixedly connected to the outer wall of the grid block, a spring fixedly connected to the outer wall of the telescopic rod, a sealing block fixedly connected to one end of the spring, a connecting ball slidably connected to the inner wall of the flow port fixedly connected to the outer wall of the sealing block, a filter screen threaded to the inner wall of the connecting cylinder, a second external spiral on the outer wall of the filter screen, and a first internal spiral at the connection between the inner wall of the connecting cylinder and the second external spiral.

[0006] Furthermore, the connecting cylinder forms an installation structure with the air outlet pipe through a first outer spiral and a second inner spiral.

[0007] Furthermore, the flow port is located on the gas output path.

[0008] Furthermore, the sealing block and the inner wall of the connecting cylinder are slidably connected, the outer wall profile of the sealing block is larger than the inner wall profile of the flow port, and the inner wall profile of the flow port is larger than the outer wall profile of the connecting ball.

[0009] Furthermore, the filter screen is installed with the connecting cylinder via a second outer spiral and a first inner spiral.

[0010] Furthermore, the filter screen is provided in two sets, and the central axes of the two sets of filter screens are arranged parallel to each other.

[0011] Furthermore, the filter screen is located at the connection port of the air outlet pipe.

[0012] The beneficial effects of this utility model are as follows: Considering that the existing stirred tank exhaust gas collection device has poor anti-backflow effect for normal gas transportation and low preliminary filtration and purification effect for gas input into the collection device, thus reducing the efficiency of the collection device in treating exhaust gas.

[0013] In use, the connecting cylinder is installed into the outlet pipe under the connection of the first external spiral and the second internal spiral threads. When the gas is continuously transported, it will press the connecting ball and squeeze the telescopic rod and spring, causing the sealing block to move away from the flow port, so that the gas can be output normally. When the output gas is less than the gas pressure at the end of the outlet pipe, the sealing block will block the flow port in time under the reaction of the spring being squeezed. At the same time, a filter screen can be detachably installed in the connecting cylinder, which can achieve the effect of preliminary purification and filtration of exhaust gas.

[0022] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a mixing vessel exhaust gas collection device, including a mixing vessel body 1, an exhaust pipe 2 at the top of the mixing vessel body 1, a connecting cylinder 3 threadedly connected to the inner wall of the exhaust pipe 2, a first external spiral 4 on the outer wall of the connecting cylinder 3, a second internal spiral 14 at the connection between the inner wall of the exhaust pipe 2 and the first external spiral 4, a flow port 5 at one end of the connecting cylinder 3, a grid block 6 fixedly connected to the other end of the connecting cylinder 3, a telescopic rod 7 fixedly connected to the outer wall of the grid block 6, a spring 8 fixedly connected to the outer wall of the telescopic rod 7, a sealing block 9 fixedly connected to one end of the spring 8 and a connecting ball 10 slidably connected to the inner wall of the flow port 5 on the outer wall of the sealing block 9, a filter screen 11 threadedly connected to the inner wall of the connecting cylinder 3, a second external spiral 12 on the outer wall of the filter screen 11, and a first internal spiral 13 at the connection between the inner wall of the connecting cylinder 3 and the second external spiral 12.

[0023] With the first outer spiral 4 and the second inner spiral 14 threaded together, the connecting cylinder 3 is installed into the outlet pipe 2. When the gas is continuously transported, it will press the connecting ball 10 and squeeze the telescopic rod 7 and the spring 8, causing the sealing block 9 to move away from the flow port 5, so that the gas can be output normally. When the output gas is less than the gas pressure at the end of the outlet pipe 2, the sealing block 9 will block the flow port 5 in time under the reaction of the spring 8 being squeezed. At the same time, a filter screen 11 can be detachably installed in the connecting cylinder 3, which can achieve the effect of preliminary purification and filtration of exhaust gas.

[0024] The connecting cylinder 3 forms an installation structure with the air outlet pipe 2 through the first outer spiral 4 and the second inner spiral 14.

[0025] The threaded connection between the first outer spiral 4 and the second inner spiral 14 enables the connecting cylinder 3 to engage with the air outlet pipe 2, facilitating the easy engagement, disassembly, and use of the connecting cylinder 3.

[0026] The flow port 5 is located on the gas output path.

[0027] The placement of the flow port 5 on the gas output path serves to prevent gas backflow.

[0028] The sealing block 9 and the inner wall of the connecting cylinder 3 are slidably connected. The outer wall profile of the sealing block 9 is larger than the inner wall profile of the flow port 5, and the inner wall profile of the flow port 5 is larger than the outer wall profile of the connecting ball 10.

[0029] The sliding connection between the sealing block 9 and the inner wall of the connecting cylinder 3 facilitates timely blocking of the flow port 5.

[0030] The filter screen 11 is installed with the connecting cylinder 3 through the second outer spiral 12 and the first inner spiral 13.

[0031] The threaded connection between the second outer spiral 12 and the first inner spiral 13 enables the filter screen 11 to engage with the connecting cylinder 3, facilitating easy disassembly and cleaning of the filter screen.

[0032] The filter screen 11 is provided in two sets, and the central axes of the two sets of filter screens 11 are arranged parallel to each other.

[0033] Among them, by setting two sets of parallel filter screens 11 between the central axes, the exhaust gas is filtered and transported in multiple ways.

[0034] The filter screen 11 is installed at the connection port of the air outlet pipe 2.

[0035] The filter screen 11 is installed at the connection port of the exhaust pipe 2 to improve the efficiency of the collection device in treating exhaust gas.

[0036] Working principle: When this stirred tank exhaust gas collection device is in use, the connecting cylinder 3 is installed into the exhaust pipe 2 under the threaded connection of the first outer spiral 4 and the second inner spiral 14. When the gas is continuously transported, it will press the connecting ball 10 and squeeze the telescopic rod 7 and the spring 8, causing the sealing block 9 to move away from the flow port 5, so that the gas can be output normally. When the output gas is less than the gas pressure at the end of the exhaust pipe 2, the sealing block 9 will block the flow port 5 in time under the reaction of the spring 8 being squeezed. At the same time, a filter screen 11 can be detachably installed in the connecting cylinder 3, which can achieve the effect of preliminary purification and filtration of exhaust gas.
