[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , the present invention provides a technical solution: an exhaust gas detection device for an external discharge of a flotation column in a workshop, including an assembly box 2. A hollow pump body 8 is fixedly connected to the front side of the assembly box 2. Two sides of the lower end of the pump body 8 are respectively connected through pipes to an air extraction pipe 3 and a gas collecting pipe 15. An upper side of the gas collecting pipe 15 is communicated with a gas collecting tank 4, and the gas collecting tank 4 is fixedly connected to the assembly box 2. The upper end of the air extraction pipe 3 is threadedly connected to an adjusting pipe, and the upper end of the adjusting pipe is communicated with a hollow air extraction head 1. A collecting component is rotatably connected inside the pump body 8. A connecting pipe 5 is fixedly connected to the upper end of the gas collecting tank 4, and the connecting pipe 5 is connected to an external gas detection device.

[0023] After placing the device at the position of the upper opening of the flotation column, the collecting component inside the pump body 8 collects the exhaust gas discharged from the flotation column at the end of the air extraction head 1. The collecting component transmits the collected exhaust gas of the flotation column to the gas collecting tank 4 through the gas collecting pipe 15, facilitating the centralized collection of the exhaust gas of the flotation column, and thus facilitating the external gas detection device to collect the exhaust gas of the flotation column, reducing the inconvenience for the external gas detection device to directly detect the exhaust gas of the flotation.

[0024] The collecting component includes an end cover 7 screwed to the front end of the pump body 8. A servo motor 9 is fixedly connected to the assembly box 2. The servo motor 9 is connected to a main shaft 13. One end of the main shaft 13 extends into the pump body 8 and is rotatably connected to the pump body 8. A hollow adjusting disc 10 is fixedly connected to the front end of the main shaft 13. A fixed shaft 12 is arranged at a non-central position inside the adjusting disc 10. The fixed shaft 12 is coaxial with the pump body 8. The front end of the fixed shaft 12 is fixedly connected to the end cover 7. Two baffle plates 11 are rotatably connected to the fixed shaft 12. Two sliding grooves are formed in the adjusting disc 10, and the baffle plates 11 are respectively inserted into the sliding grooves, and the baffle plates 11 are in contact with the inner wall of the pump body 8.

[0025] By turning on the servo motor 9, the servo motor 9 drives the main shaft 13 to rotate, and the main shaft 13 drives the adjusting disc 10 to rotate. Due to the insertion of the dial 11 into the chute, thus through the rotation of the adjusting disc 10, the gas at the penetrating part of the air extraction pipe 3 and the pump body 8 is transferred to the part between the right side of the adjusting disc 10 and the inner wall of the pump body 8, thereby pushing the gas into the gas collecting pipe 15 and entering the gas collecting tank 4 through the gas collecting pipe 15, facilitating the entry of the air in the air extraction pipe 3 into the gas collecting tank 4; the outer end of the dial 11 contacts the inner wall of the pump body 8, and the opening position of the gas collecting pipe 15 is on the upper side of the bottom of the pump body 8, thus facilitating the compression of the gas in the chamber surrounded by the upper sides of the two dials 11 into the inner side of the gas collecting pipe 15.

[0026] The pump body 8 is provided with two circular grooves, and circular plates 16 are inserted into the circular grooves. Slots are opened on the inner sides of the circular plates 16, and the dials 11 are inserted into the slots.

[0027] The circular plate 16 is made of plastic material.

[0028] The circular plate 16 made of plastic material plays a sealing role.

[0029] The air extraction head 1 is arranged in a horn shape.

[0030] The air extraction head 1 is in a horn shape, facilitating the collection of the exhausted gas discharged from the flotation column.

[0031] The gas collecting pipe and the connecting pipe 5 are both fixedly connected with ball valves 14.

[0032] The ball valve 14 has the function of opening and closing, which has been popularized in the market and will not be elaborated here.

[0033] Two insertion rods 6 are fixedly connected to the rear side of the assembly box 2, and an arc-shaped attachment groove is opened at the rear part of the assembly box 2.

[0034] By inserting the two insertion rods 6 into the inner wall of the flotation column, it is convenient to collect the exhausted gas discharged from the flotation column through the air extraction head 1.

[0035] When the present utility model is in use, first, after placing the device at the opening position on the upper side of the flotation column, the collection component in the pump body 8 collects the exhausted gas discharged from the flotation column at the end of the air extraction head. The collection component transfers the collected exhausted gas discharged from the flotation column to the gas collecting tank 4 through the gas collecting pipe 15, facilitating the centralized collection of the exhausted gas discharged from the flotation column. After that, it is convenient for external gas detection equipment to collect the exhausted gas discharged from the flotation column, reducing the inconvenience for external gas detection equipment to directly detect the exhausted gas discharged from the flotation column.

[0036] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
