Description

TECHNICAL FIELD

[0001] The utility model relates to a filter, specifically to a quartz sand filter. BACKGROUND

[0002] The quartz sand filter is a high-efficiency filtering device which uses quartz sand as filtering medium to filter water with high turbidity through a certain thickness of granular or non-granular quartz sand under certain pressure, effectively intercepting and removing suspended matter, organic matter, colloidal particles, microorganisms, chlorine, odor and part of heavy metal ions in water, so as to reduce water turbidity and purify water quality.

[0003] During use of the quartz sand filter, the filtered substances are accumulated in the quartz sand, which easily causes blockage and reduces the filtering efficiency. The mainstream solution to the technical problem is backwashing, but the backwashing water flow is slow and the flushing force is small due to the dense quartz sand and the accumulation of various substances in the voids, which causes poor flushing efficiency.

[0034] Embodiment:

[0035] Referring to Figure 1 and Figure 2 , the embodiment discloses a quartz sand filter, comprising a rack 10, a tank 20, a baffle 30, a corrugated pipe 40, a stud 50 and a hand wheel 60. Wherein, the tank 20 is arranged on the rack 10, the baffle 30 is arranged in the tank 20, the baffle 30 is arranged between the baffle 30 and the tank 20, the stud 50 is rotationally connected with the baffle 30 and fixedly connected with the hand wheel 60. The baffle 30 can be directly driven to move in the tank 20 through the hand wheel 60 and the stud, and the volume of the tank 20 is changed to realize efficient flushing of the quartz sand in the tank 20.

[0036] Specifically, the length direction of the tank 20 is arranged along the horizontal direction, and one water inlet 21 and one water outlet 22 are arranged at two ends of the tank 20 respectively, and a flushing port 23 is arranged at the bottom of the tank 20. Flanges are arranged on the water inlet 21, the water outlet 22 and the flushing port 23 respectively for connecting with corresponding water inlet / outlet pipelines.

[0037] The baffle 30 is movably arranged in the tank 20, and the baffle 30 divides the inside of the tank 20 into two parts. The water inlet 21 is located at the end of one part, the water outlet 22 is located at the end of the other part, and the baffle 30 is close to the water outlet 22. A connecting port 31 is arranged on the baffle 30, which is arranged corresponding to the water outlet 22. The corrugated pipe 40 is installed on one end of the water outlet 22 and the other end of the connecting port 31.

[0038] One end of the stud 50 is rotationally connected with the baffle 30, and the other end of the stud 50 penetrates one end of the tank 20 having the water outlet 22. The end of the tank 20 has a threaded hole, and the stud 50 matches the threaded hole.

[0039] A hand wheel 60 is arranged on the end of the stud 50 penetrating the tank 20. The stud 50 can be directly driven to rotate by rotating the hand wheel 60, and the baffle 30 is driven to move in the tank 20.

[0040] The working principle of the embodiment is that the baffle 30 is driven to move in the tank 20 by the stud 50 and the hand wheel 60, and the quartz sand is filled on one side of the baffle 30. In the normal filtering process, the baffle 30 tightly abuts the quartz sand in one end of the tank 20, and the water to be filtered is input into the tank 20 through the water inlet 21. The filtered water is discharged through the connecting port 31, the corrugated pipe 40 and the water outlet 22.

[0041] During backwashing, the baffle 30 is moved by the stud 50 and the hand wheel 60, so that the space filled with quartz sand in the tank 20 is increased, and then water is flushed into the tank 20 through the flushing port 23. During this process, since the quartz sand is no longer in a compacted state, the substances accumulated in the quartz sand are separated from the quartz sand under the action of high-pressure water, and the quartz sand is also moved under the action of high-pressure water, so that the quartz sand is rinsed. The water after backwashing is discharged from the water outlet 22.

[0042] In the technical solution, the quartz sand can be efficiently flushed.

[0043] In one specific embodiment,

[0044] The filter further comprises a supporting wheel 70, a traction machine 80 and a cable 90, wherein one end of the tank 20 close to the water inlet 21 is rotationally arranged on the rack 10. Specifically, one end of the cable 90 is fixedly arranged on the other end of the tank 20, the supporting wheel 70 is arranged above the end of the tank 20 rotationally connected with the rack 10, the traction machine 80 is arranged on the rack 10, and the traction machine 80 is located at a distance from the end of the tank 20 rotationally connected with the rack 10.

[0045] The end of the cable 90 away from the tank 20 is fixedly arranged on the traction end of the traction machine 80 after passing around the supporting wheel 70.

[0046] In this embodiment, the tank 20 can be driven to rotate on the rack 10 by arranging the traction machine 80, the supporting wheel 70 and the cable 90, and the tank 20 is kept in a vertical state. At this time, the water inlet 21 is located at the bottom of the tank 20, the water outlet 22 is located at the top of the tank 20, and the flushing port 23 is located at the side of the tank 20.

[0047] When the tank 20 is in a vertical state, normal filtering work can be carried out, and the filtering effect can be improved by the way of bottom water inlet.

[0048] When the quartz sand needs to be flushed, the tank 20 is lowered by the traction machine 80 and placed on a horizontal surface to start the above-mentioned flushing work.

[0049] Preferably, the rack 10 is provided with a support frame 12 located below the end of the tank 20 away from the traction machine 80, and the support frame 12 is used to support the tank 20 in a horizontal state. The top of the support frame 12 has an arc-shaped rod, which increases the contact area between the support frame 12 and the tank 20, thereby avoiding indentation or damage to the outer wall of the tank 20.

[0050] In another preferred embodiment, the traction machine 80 comprises two traction wheels 83, and the support wheels 70 and the pull ropes 90 are symmetrically arranged on both sides of the tank body 20. By symmetrically arranging the traction wheels 83, the support wheels 70 and the pull ropes 90 on both sides of the tank body 20, the tank body 20 can be kept stable when the tank body 20 is driven to rotate. In addition, a support table 11 is arranged on the frame 10, which is used to support the tank body 20 in a vertical state. When the tank body 20 is in a vertical state, the support table 11 supports the bottom of the tank body 20.

[0051] In another preferred embodiment, the two traction wheels 83 are arranged on the same shaft 81, and the shaft 81 is driven by a motor 82. The traction wheels 83 are the traction end of the traction machine 80.

[0052] In another specific embodiment, a strip-shaped observation window 24 is arranged on the tank body 20. Through the observation window 24, the cleaning state of the quartz sand in the tank body 20 and whether the baffle 30 can press the quartz sand can be observed.

[0053] The above-mentioned embodiments only express the specific implementation manners of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
