Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a cooling tower sand filter. Background Art

[0002] Cooling tower sand filter is a filter used in cooling towers, mainly used to filter impurities and particulate matter in water to ensure the cleanliness of water quality and cooling effect; this sand filter usually consists of a cylindrical outer shell and an internal filter medium, and the filter medium is generally particulate matter such as sand or anthracite.

[0003] When water flows through the cooling tower sand filter, larger particles will be blocked by the filter medium, while smaller particles will be adsorbed on the surface of the filter medium, thereby achieving a filtering effect. As the use time increases, the filter medium will gradually become clogged, so it needs to be replaced regularly. However, when the sand filter is currently replacing the medium, the shell cannot be fully unfolded, and the medium can only be exported and replaced by extraction, which is rather troublesome. For this reason, we propose a cooling tower sand filter. Utility Model Content

[0022] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0023] Example:

[0024] like Figure 1-Figure 6As shown, a cooling tower sand filter comprises a tank body 1, a water inlet 2, a water outlet 3, a medium inlet 4, a support column 5, and a connecting tube 6. The top surface of the tank body 1 is provided with a water inlet 2, and the upper and lower ends of one side wall of the tank body 1 are respectively provided with a medium inlet 4 and a water outlet 3. The bottom surface of the inner wall of the tank body 1 is fixedly installed with a connecting tube 6, and a plurality of support columns 5 are fixedly installed on the bottom surface of the tank body 1. The top surface of the connecting tube 6 is provided with a medium groove 7, and the bottom surface of the medium groove 7 is provided with a guide outlet 9. A discharge port 8 connected to the guide outlet 9 is provided at the center of the bottom surface of the tank body 1. The medium groove 7 is in a conical shape with a larger upper portion and a smaller lower portion. A blocking block 12 is inserted into the inner wall of the top opening of the guide outlet 9, and the top surface of the blocking block 12 protrudes above the top opening of the guide outlet 9. A connecting groove 13 is provided on the bottom surface of the blocking block 12, and the connecting groove 13 extends from bottom to top to above the opening of the guide outlet 9, and the connecting groove 13 does not exceed the top surface of the blocking block 12, the inner wall of the connecting groove 13 is inserted with an insert block 131, the connecting groove 13 and the insert block 131 are both in a cross-shaped shape, a support shaft 14 is fixedly installed on the bottom surface of the insert block 131, a collar is sleeved on the outer surface of the support shaft 14, a support rod 16 is fixedly installed on one side wall of the collar, a hydraulic rod 17 is provided on the top surface of one end of the support rod 16 away from the support shaft 14, the top surface of the shell of the hydraulic rod 17 is fixed to the bottom edge of the discharge port 8, a water outlet 10 connected to the water outlet 3 is opened on one side of the inner wall of the medium tank 7, and an isolation net 11 is fixedly installed on the inner wall of the top opening of the water outlet 10, so that the filtered water can be discharged normally, and the isolation net 11 can block the outflow of the medium.

[0025] The working principle of the above technical solution is as follows:

[0026] When replacing the medium, the hydraulic rod 17 is directly driven to extend the telescopic end downward. At this time, the support rod 16 will move downward with the collar, so that the support shaft 14 is pulled down. At this time, the pulling of the support shaft 14 can make the plug 131 leave the inner wall of the connecting groove 13. At this time, the side wall of the blocking block 12 can leak out of the opening of the connecting groove 13, and then the medium is guided downward through the inner wall of the medium groove 7 and discharged from the discharge port 8. When the medium is discharged, the hydraulic rod 17 is retracted to restore the support shaft 14 to its original position, and then the plug 131 is inserted back into the inner wall of the connecting groove 13, and then new medium can be added to the inside of the tank body 1 from the medium inlet 4.

[0027] In another embodiment, if Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a first bevel gear 18 is fixedly installed at the bottom end of the support shaft 14, and a second bevel gear 19 is meshedly connected to a side wall of the first bevel gear 18, and a rotating shaft 20 is fixedly installed on one side of the second bevel gear 19. A motor 21 is provided on one side of the bottom of the discharge port 8, and the output end of the motor 21 rotates with the rotating shaft 20. The collar is specifically a bearing 15, and the inner wall of the bearing 15 is fixedly connected to the outer surface of the support shaft 14. A lever 22 is fixedly installed on both sides of the top surface of the blocking block 12, and the lever 22 is inclined, and the bottom surface of the lever 22 is in contact with the inner wall of the medium tank 7. A support seat 23 is fixedly installed at the eccentric position of the bottom surface of the tank body 1, and the support seat 23 is U-shaped. The side wall of the motor 21 is tightly fitted with the inner wall of the support seat 23. By setting the support seat 23 with a U-shaped opening, the motor 21 can be conveniently placed and used. At the same time, the side wall of the motor 21 is tightly fitted with the inner wall of the support seat 23, so that the rotation of the motor 21 is stable.

[0028] When using the device, the motor 21 together with the rotating shaft 20 and the second bevel gear 19 are placed on the inner wall of the support seat 23, and then the second bevel gear 19 is meshed with the tooth groove of the first bevel gear 18. Then the motor 21 is driven to make the rotating shaft 20 rotate with the second bevel gear 19, so that the first bevel gear 18 can rotate and rotate with the support shaft 14. In this state, the rotation of the support shaft 14 can make the plug block 131 stuck in the connecting groove 13 rotate with the blocking block 12, and then the lever 22 can be rotated on the inner wall of the medium groove 7 to stir the medium to avoid accumulation. When the discharge port 8 needs to replace the medium, the motor 21 needs to be taken out of the support seat 23 to allow the support shaft 14 to move downward without restriction.

[0029] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
