Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet water quality requirements for drainage or reuse. It involves the integrated application of multiple fields, including physics, chemistry, and biology. Wastewater treatment is widely used in various fields, including construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscapes, healthcare, and catering, and is closely related to people's lives and the quality of the environment. Currently, sewage treatment often requires the use of sewage treatment tanks.

[0003] Traditional sewage treatment equipment usually uses a fixed filter structure. Although this design can effectively intercept suspended matter in sewage, when the filter is clogged or aged, the process of replacing the filter is very complicated. A lot of sludge and impurities will be deposited inside, making it difficult to remove the filter for cleaning. Utility Model Content

[0004] The utility model aims to provide a sewage treatment device to solve the problem of complex filter screen replacement in the prior art.

[0005] A sewage treatment device in this solution includes a treatment tank and a group of symmetrically arranged lifting mechanisms. A filter screen is provided in the treatment tank, and the lifting mechanisms are used to raise and lower the filter screen at a uniform speed.

[0006] Furthermore, "Π"-shaped connecting rods are provided on both sides of the filter screen, and the connecting rods are hung on the sides of the treatment tank. The lifting mechanism drives the filter screen to rise and fall through the connecting rods.

[0007] Furthermore, the lifting mechanism includes a spiral-shaped abutment block, the radius of which gradually increases from the center outward. A motor is connected to the center of the abutment block to drive its rotation, and the abutment block contacts the connecting rod. The motor drives the abutment block to rotate, and the top of the abutment block contacts the connecting rod during rotation. Since the radius of the abutment block gradually increases from the center, it can gradually move the connecting rod upward during rotation, thereby raising the filter screen via the connecting rod. Since there are two lifting mechanisms, both sides of the filter screen can be lifted simultaneously, allowing the filter screen to rise in parallel.

[0008] Furthermore, a connecting plate is provided at the bottom of the connecting rod, and the supporting block contacts the bottom of the connecting plate. The connecting plate is provided to increase the contact area and make the lifting more stable.

[0009] Furthermore, a locking block is provided at an angled end of the abutment block, and a slot is provided at an angled bottom of the connecting plate for retaining the locking block. When the abutment block rotates and raises the connecting plate to its highest point, the locking block engages in the slot, preventing the abutment block from further rotation. After the motor is flipped, the filter can be lowered. The locking block and slot serve to limit the abutment block and the filter.

[0010] The beneficial effects of this solution are: the device in this solution can lift the filter screen at a uniform speed, smoothly and in parallel, and when the filter screen moves to the highest position, the cooperation of the card block and the card slot will lock the connection between the support block and the connecting plate, preventing the filter screen from continuing to move, so that the filter screen can be cleaned. At this time, it can be cleaned directly or removed for cleaning. The rising level of the filter screen can lift up floating objects floating on the surface of the treatment pool, and the floating objects can be cleaned together with the sludge. After cleaning, the motor can be turned over to place the filter screen in the treatment pool to continue filtering. At this time, limestone can also be added for sewage treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a structural diagram of a sewage treatment device of the utility model;

[0012] Figure 2 for Figure 1 AA section view. DETAILED DESCRIPTION

[0013] The following is a further detailed description through specific implementation methods:

[0014] The reference numerals in the drawings of the specification include: treatment tank 1, supporting block 2, clamping block 3, connecting plate 4, connecting rod 5, filter screen 6, and clamping slot 7.

[0015] The embodiment is basically as shown in the attached Figure 1 and Figure 2 As shown: A sewage treatment device, including a treatment tank 1 and a group of symmetrically arranged lifting mechanisms, a filter screen 6 is provided in the treatment tank 1, and a "Π"-shaped connecting rod 5 is provided on both sides of the filter screen 6. The connecting rod 5 is hung on the side of the treatment tank 1, and a connecting plate 4 is provided at the bottom of the connecting rod 5. The lifting mechanism includes a spiral supporting block 2, the radius of the supporting block 2 gradually increases from the center to the outside, the center of the supporting block 2 is connected to a motor that drives it to rotate, the supporting block 2 is in contact with the connecting plate 4, and the end of the supporting block 2 is inclined to provide a clamping block 3, and the bottom of the connecting plate 4 is inclined to provide a clamping groove 7 for clamping the clamping block 3.

[0016] When in use, the motor drives the supporting block 2 to rotate. When the supporting block 2 rotates, the top of the supporting block 2 abuts the connecting plate 4. Since the radius of the supporting block 2 gradually increases from the center, the connecting plate 4 can be gradually moved up during the gradual rotation, thereby lifting the filter screen 6 through the connecting rod 5. Since there are two lifting mechanisms, both sides of the filter screen 6 can be lifted at the same time, so that the filter screen 6 can rise in parallel. When the filter screen 6 moves to the highest position, the cooperation of the card block 3 and the card slot 7 will lock the connection between the supporting block 2 and the connecting plate 4 to prevent the filter screen 6 from continuing to move. After rising, the filter screen 6 can be removed, or the sludge on the filter screen 6 can be directly cleaned. The horizontal rise of the filter screen 6 can lift up the floating objects floating on the surface of the treatment tank 1, and the floating objects can be cleaned together with the sludge. After cleaning, the motor can be turned over to place the filter screen 6 in the treatment tank 1 to continue filtering.

It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
