Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment devices, and particularly relates to a composite biological trickling filter. Background Art

[0002] The biological filter is a relatively advanced process technology in the biochemical treatment of sewage in recent years. It has been widely used and promoted in the treatment of domestic sewage and has achieved good results.

[0003] Existing devices usually use a rotary water distributor to spray sewage. Since the position of most rotary water distributors is fixed and cannot be adjusted up and down according to the size of the water flow, the sewage sprayed from the nozzle to the top of the biological filter will have a heavy water distribution area or will not be completely distributed on the top of the biological filter, which affects the filtering effect of the device and reduces the filtering efficiency of the device. Utility Model Content

[0004] The purpose of the utility model is to provide a composite biological trickling filter. By adjusting the components, the water spray box can move up and down on the inner wall of the water distributor, which solves the problem that the sewage sprayed from the nozzle to the top of the biological filter will have a heavy water distribution area or is not completely distributed on the top of the biological filter, which affects the filtering effect of the device and reduces the filtering efficiency of the device.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

A fixed block 1 is fixedly connected to the outer surface of the slide rail, and the number of the fixed blocks 1 is four. By setting the slide groove, the water distributor can operate more stably when rotating.

[0015] 2. The utility model sets a nozzle. Specifically, when the water distributor rotates, as the distance from the central axis increases, the area that the nozzle needs to spray becomes larger. The size of the corresponding nozzle is increased, so that the water flow rate of the nozzle farther from the central axis is greater, so that the water distributor can evenly spray sewage to the top of the biological filter, thereby improving the practicability of the device.

[0027] See also Figure 1-6 As shown, the utility model is a composite biological trickling filter, including a trickling filter body 1, a drain pipe 2 is fixedly connected to the right side of the trickling filter body 1, a slide rail 3 is fixedly connected to the top of the trickling filter body 1, a cylinder 4 is fixedly connected to the bottom of the inner wall of the trickling filter body 1, a circular groove 1 is opened inside the cylinder 4, an adjustment component 22 is arranged above the cylinder 4, the adjustment component 22 includes a water distribution tank 211, and water distributors 212 are fixedly connected to the four sides of the water distribution tank 211, and the four water distributors 212 are arranged in a circular array with the water distribution tank 211 as the center, and the parts contained in the four water distributors 212 are the same.

[0028] The bottom of the water distribution tank 211 is rotatably connected to the inner wall of the circular groove 1, and the top of the water distributor 212 is fixedly connected to a fixed block 213.

The front and back sides of the two moving blocks 216 are rotatably connected to the rotating rod 217. A slide groove 1 is opened inside the water distributor 212. By setting the adjustment component 22, specifically turning on motor 220 to drive the two moving blocks 216 to move, the water spray box 219 moves up and down on the inner wall of the water distributor 212, and the distance between the nozzle 221 and the biological filter 6 is adjusted, so that the water distributor 212 can distribute sewage, and there will be no heavy water distribution area or the water is not completely distributed on the top of the biological filter, thereby improving the filtration efficiency of the device.

[0030] A water spray box 219 is slidably connected to the inner wall of the slide, and round rods 218 are fixedly connected to the front and back of the water spray box 219.

A plurality of nozzles 221 are fixedly connected to the bottom of the water spray box 219, and the plurality of nozzles 221 are set in different sizes. By setting the nozzles 221, specifically when the water distributor 212 rotates, as the distance from the central axis increases, the area that the nozzle needs to spray is also larger, and the size of the corresponding nozzle 221 is increased, so that the farther the nozzle 221 is from the central axis, the greater the water flow rate sprayed, so that the water distributor can evenly spray sewage to the top of the biological filter, thereby improving the practicability of the device.

[0031] A slide groove 2 is provided inside the slide rail 3, and the inner wall of the slide groove 2 is slidably connected to the side of the water distributor 212 away from the water distribution tank 211.

The left side of the water pipe 5 passes through the cylinder 4 and the trickling filter body 1 respectively and extends to the outside.

[0035] A specific application of this embodiment is: first, turn on the motor 220 to drive the two-way threaded rod 214 to rotate. During the rotation of the two-way threaded rod 214, the two moving blocks 216 will be driven to move away from each other. During the movement of the two moving blocks 216, the four rotating rods 217 will be driven to rotate. The four rotating rods 217 will rotate in the direction close to the fixed block 3 215 to make the water spray box 219 move downward on the inner wall of the water distributor 212, so that the device can adjust the distance between the nozzle 221 and the biological filter 6, so that the water distributor 212 can distribute the sewage and spray the sewage more evenly on the top of the biological filter 6. The external sewage is pumped into the water distribution tank 211 along the water pipe 5 through the water pump. Four circular grooves are opened inside the water distribution tank 211 to connect the four water distributors 212 respectively. The sewage entering the water distribution tank 211 will be evenly discharged from the circular grooves. The sewage will enter the inner wall of the four water distributors 212, and the sewage entering the water distributors 212 will flow into the spray box 219, and the sewage will be sprayed to the top of the biological filter 6 from several nozzles connected to the bottom of the spray box 219. The motor 13 is turned on to drive the rotating shaft 14 to rotate, and the rotating shaft 14 will drive the water distribution box 211 to rotate. The rotation of the water distribution box 211 will drive the four water distributors 212 to continuously rotate on the inner wall of the drip filter body 1, so that the biological filter 6 can be completely sprayed by the nozzles 221. Since the drip filter body 1 is circular, when the four water distributors 212 rotate with the increase of the center axis distance, the spraying area is also larger. By setting several nozzles 221 of different sizes, the amount of sewage received by the top of the biological filter 6 when the water distributor 212 rotates is the same, so that the filtration efficiency of the biological filter 6 is higher, and the practicability of the device is improved.
