Technical Field

[0001] This utility model relates to the field of dosing device technology, specifically a dosing device for coal slime flotation. Background Technology

[0002] Coal slime flotation is a commonly used coal separation process. By adding reagents and air, it separates coal and impurities from the ore and impurities based on the density and surface property differences between them. For effective coal slime flotation, a specialized dosing device is needed to uniformly add the reagents to the coal slime.

[0003] Utility model patent CN217725864U discloses a coal slime flotation reagent dosing and metering device, including a flotation machine with flotation inlets and outlets on both sides. The top of the flotation machine has reagent inlets A and B spaced apart. It also includes two reagent cartridges, cartridge A and cartridge B. This utility model effectively solves the problem of errors and poor flotation results caused by manual reagent dosing in traditional coal slime flotation.

[0004] In existing technologies, during the use of dosing devices, wastewater from the flotation tank can easily enter the reagent output pipeline, causing pollution. Furthermore, it is inconvenient to replenish the reagent cartridge in a timely manner during dosing, which is detrimental to the continuity of the dosing process. Therefore, improvements are needed.

A float is fixedly connected to the outside of the guide seat, and contact blocks are fixedly connected to both the upper and lower ends of the float. Contact switches are installed at the top and bottom of the inner wall of the medicine cartridge. By designing this liquid addition mechanism, the medicine cartridge can be automatically replenished with liquid.

[0009] Preferably, the guide seat has a guide groove inside, and a guide rod is slidably connected inside the guide groove. By designing the guide groove, the guide seat can slide along the guide rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1.

When the liquid medicine is output from the output head, the baffle is pushed open and separated from the output head, allowing the liquid medicine to be output. After the liquid medicine is output, the baffle can automatically reset and re-seal the output head, which can prevent wastewater from the flotation tank from entering the fixed pipe and causing pollution.

[0014] 2. This utility model utilizes the design of a float ball, which floats on the surface of the liquid inside the medicine cylinder. When the liquid level inside the medicine cylinder is low, the float ball will descend and make the contact block contact the contact switch. At this time, the solenoid valve will open and output the liquid inside the connecting cylinder to the inside of the medicine cylinder, thereby achieving the purpose of automatically replenishing the liquid inside the medicine cylinder and ensuring the continuity of the dosing process.

A dosing mechanism 8 is provided on the reagent cartridges 2. An output mechanism 9 is provided on the output head 7.

[0022] Please see Figure 1 , Figure 2 , Figure 3The liquid addition mechanism 8 includes a connecting port 81. The connecting port 81 is fixedly connected to the inside of the connecting cylinder 11. The connecting port 81 is fixedly connected to the cartridge 2. A solenoid valve 82 is provided on the connecting port 81. A guide rod 83 is fixedly connected to the inside of the cartridge 2. A guide seat 84 is slidably sleeved on the outside of the guide rod 83. A guide groove 85 is opened inside the guide seat 84. The guide rod 83 is slidably connected inside the guide groove 85. By designing the guide groove 85, the guide seat 84 can slide along the guide rod 83. A float ball 86 is fixedly connected to the outside of the guide seat 84. A contact block 87 is fixedly connected to the upper and lower ends of the float ball 86. A contact switch 88 is provided at the top and bottom of the inner wall of the cartridge 2. By designing the liquid addition mechanism 8, the liquid can be automatically added to the inside of the cartridge 2.

[0023] Please see Figure 1 , Figure 2 , Figure 4 The output mechanism 9 includes a plug 91, which is slidably fitted inside the output head 7. A connecting rod 92 is fixedly connected to the bottom of the plug 91, and a spring 93 is provided on the outside of the connecting rod 92. One end of the spring 93 is fixedly connected to the plug 91, and the other end of the spring 93 is fixedly connected to the fixing strip 94. By designing the spring 93, the force of the spring 93 can act on the plug 91. The fixing strip 94 is slidably fitted on the outside of the connecting rod 92 and is fixedly connected to the output head 7. A baffle 95 is fixedly connected to the bottom of the connecting rod 92, and a rubber sleeve 96 is fixedly fitted on the outside of the baffle 95.

[0024] The specific implementation process of this utility model is as follows: When it is needed to add chemicals, the water pump 3 draws the chemical solution inside the chemical cylinder 2 through the inlet 4. Then, the chemical solution enters the fixed pipe 6 through the outlet 5. The chemical solution then enters the output head 7, which pushes the plug 91 to move down. The plug 91 drives the connecting rod 92 to move down. At the same time, the plug 91 presses down the spring 93. Then, the connecting rod 92 drives the baffle 95 and the rubber sleeve 96 to move down and separate from the output head 7. At this time, the chemical solution flows out through the gap between the plug 91 and the inner wall of the output head 7 and is finally output through the output head 7, which can add chemicals to the flotation tank. After the chemical addition is completed, the water pump 3 stops working. Under the elastic action of the spring 93, the plug 91 and the baffle 95 will be pushed back to their original positions. At this time, the output head 7 can be resealed, which can prevent the sewage inside the flotation tank from entering the fixed pipe 6 and causing pollution.

[0025] As the liquid medicine is output from the cartridge 2, when the liquid level inside the cartridge 2 decreases, the float 86 will descend with the liquid medicine. The float 86 drives the guide seat 84 to slide along the guide rod 83, so that the lower contact block 87 of the float 86 contacts the contact switch 88. At this time, the solenoid valve 82 opens, and then the liquid medicine inside the connecting cylinder 11 is output into the cartridge 2 through the connecting port 81. As the liquid level inside the cartridge 2 rises, the float 86 can rise again and contact the upper contact switch 88. At this time, the solenoid valve 82 closes, thereby achieving the purpose of automatically replenishing the liquid medicine inside the cartridge 2, which can ensure the continuity of the dosing process.
