[0027] Refer to Figures 1-4 is the structural schematic diagram of the present utility model. An acid fracturing plugging agent mixing device for oil and water wells includes a mixing box 1. A mixing discharge pipe 2 is arranged on the right side of the mixing box 1. A mixing material box 3 is arranged on the top of the mixing box 1. The mixing material box 3 is used for storing the acid fracturing plugging agent to be mixed. A throat is formed at a position with a relatively small internal space in the mixing discharge pipe 2, and a diffuser is formed at a position with a relatively large internal space on the right side of the mixing discharge pipe 2. An attracting space is formed inside the mixing box 1. An intake pipe 4 is arranged inside the left side of the mixing box 1. During the gas transmission process, the intake pipe 4 enters the inside of the mixing box 1, forms a negative pressure through the attracting space, and after forming the negative pressure, the acid fracturing plugging agent to be mixed is sucked into the inside of the mixing box 1, and the mixing work is carried out through the gas, so as to improve the mixing effect.

[0028] The acidizing plugging removal agent after mixing enters the inside of the mixing and discharging pipe 2, and after entering, it is diffused and discharged through the diffusion pipe. The mixing and discharging pipe 2 is connected to the acid fume recovery device to carry out the treatment work. A connecting piece 5 is arranged at the top end of the air inlet pipe 4. The connecting piece 5 is used to provide an installation position for the connecting head 6. At the same time, the water delivery pipe 7 is connected to the connecting head 6. During the treatment process, the delivery pipe 7 will enter the inside of the air inlet pipe 4 to cooperate with the harmful gas in the acidizing plugging removal agent that can be diluted and mixed with the gas. Inside the top end of the connecting piece 5, there is a connecting head 6. At the top end of the connecting head 6, there is a water delivery pipe 7. Inside the bottom end of the connecting piece 5, there is a filter plate 8. The filter plate 8 is used to filter the gas and water. At the bottom end of the air inlet pipe 4, there is a sealing assembly. After the sealing assembly is opened, the cleaning work can be carried out.

[0029] It should be noted that a groove for installing the filter plate 8 is arranged inside the connecting piece 5. At the same time, a groove consistent with the installation groove is arranged at the inner bottom end of the air inlet pipe 4. The filter plate 8 can be inserted and pulled out from the inside of the groove. The groove is used to provide installation limit for the filter plate 8 and can increase the use strength of the filter plate 8. The filter plate 8 is arranged in an arc shape inside the connecting piece 5 and the air inlet pipe 4.

[0030] Specifically, the sealing assembly includes a water outlet pipe 9. The water outlet pipe 9 is arranged inside the bottom end of the air inlet pipe 4.

After connection, connect it to the connecting piece 5. After connection, add the acidizing plugging removal agent to be mixed into the mixing material box 3. After adding, the gas enters the inside of the mixing box 1 through the air inlet pipe 4. After entering, a negative pressure is formed. After the negative pressure is formed, the acidizing plugging removal agent inside the mixing box 3 is sucked into the inside of the mixing box 1 for mixing work. After mixing, it enters the mixing and discharging pipe 2 for diffusion and discharge. After discharge, it enters the inside of the acid fume recovery device for treatment work. When it is necessary to dilute and treat the harmful substances during the mixing process, the water delivery pipe 7 delivers water into the inside of the air inlet pipe 4. After entering, it is atomized in cooperation with the gas, and the atomized gas is used for mixing and diluting the harmful substances. When it is necessary to clean the filter plate 8, remove the seal 10 from the water outlet pipe 9. After removal, wash the filter plate 8 with the water delivered by the water delivery pipe 7. The impurities washed down are discharged through the water outlet pipe 9, thus completing the cleaning work. When it is necessary to replace the filter plate 8, remove the connecting piece 5 from the air inlet pipe 4. After removal, take out the filter plate 8 from the inside of the air inlet pipe 4 and carry out the replacement work.
