Description

Technical Field

[0001] This utility model belongs to the field of wastewater phosphorus removal technology, specifically referring to an attapulgite adsorption phosphorus removal device. Background Technology

[0002] Attapulgite is a natural layered chain magnesium aluminum silicate mineral with a unique fibrous crystal structure and porous structure. Attapulgite adsorption for phosphorus removal refers to the process of removing phosphorus (usually in the form of phosphate) from water bodies (such as sewage, wastewater, and polluted natural water bodies) by utilizing the adsorption properties of attapulgite mineral.

[0003] In existing technologies, attapulgite after phosphorus removal needs to be replaced periodically. Since attapulgite is in block form, it is generally placed directly into the wastewater for phosphorus adsorption and removal. However, this method has drawbacks: it is inconvenient to replace the attapulgite afterward, and the attapulgite is in a static state, resulting in low phosphorus adsorption and removal efficiency. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that, in the prior art, when adsorbing and removing phosphorus from wastewater, it is inconvenient to replace attapulgite, and at the same time, when attapulgite is in a static state during adsorption, the phosphorus removal efficiency is low.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: an attapulgite adsorption and phosphorus removal device includes a treatment tank, with trough plates symmetrically fixed to the upper end of the treatment tank, a support slidably arranged across the trough plate, a sliding adsorption drive device arranged in the trough plate and poweredly connected to the support, a depth adjustment device arranged on the support, a box with an open bottom connected to the lower end of the depth adjustment device, mesh holes evenly distributed on all four sides of the box, a feeding port arranged at the upper end of the box, and a locking device arranged at the bottom of the box.

[0006] Furthermore, the locking device includes a sealing plate, which is L-shaped and passes through the bottom of the box. A buckle is provided on the outer end face of the sealing plate. A fixing block is provided on the side wall of the box, and a buckle plate is hinged to the fixing block. The buckle plate can be fastened to the buckle ring. Pushing the sealing plate into the box and fastening it to the buckle ring can lock the sealing plate. Pulling open the sealing plate allows the attapulgite in the box to be unloaded and replaced.

[0007] Furthermore, the sliding adsorption drive device includes a motor, which is fixed to the end face of the tank plate. The output end of the motor is provided with a lead screw and is threadedly connected to the support. On the other side of the tank plate, a sliding rod is fixed and passes through the support. The sliding rod is parallel to the lead screw. By rotating the lead screw, the support can drive the box to move horizontally, so that the attapulgite can be moved to adsorb phosphorus in the treatment tank, which is more efficient.

[0008] Furthermore, the depth adjustment device includes an electric push rod, which is fixed to the top wall of the bracket. The output end of the electric push rod is connected to the housing. Two sets of guide rods are fixed to the upper end of the housing and located on both sides of the electric push rod. The guide rods extend upward through the bracket, and the depth of the housing can be adjusted by the electric push rod.

[0009] Furthermore, the guide rod is parallel to the extension and retraction direction of the electric push rod.

[0010] The beneficial effects achieved by adopting the above-described structure are as follows:

[0011] 1. This utility model, by setting a locking device, allows the attapulgite inside the box to fall down when the sealing plate is pulled, thus enabling the replacement of the attapulgite inside the box.

[0012] 2. This utility model, by setting up a sliding adsorption drive device, uses a motor to drive a lead screw to rotate, and the lead screw drives a support to slide in the trough plate, which can realize the movement of the box. Thus, the attapulgite inside the box can move to adsorb phosphorus in the treatment tank, thereby improving the adsorption efficiency of phosphorus. Attached Figure Description

Detailed Implementation

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0020] like Figure 1-4 This utility model discloses an attapulgite adsorption and phosphorus removal device, comprising a treatment tank 1, with trough plates 2 symmetrically fixed to the upper end of the treatment tank 1, a support 3 slidably arranged across the trough plate 2, a sliding adsorption drive device 4 arranged in the trough plate 2 and poweredly connected to the support 3, a depth adjustment device 5 arranged on the support 3, a box 6 with an open bottom connected to the lower end of the depth adjustment device 5, mesh holes 7 evenly distributed on all four sides of the box 6, a feeding port 8 arranged at the upper end of the box 6, and a locking device 9 arranged at the bottom of the box 6.

[0021] like Figure 1-3 The locking device 9 includes a sealing plate 10, which is L-shaped and passes through the bottom of the box 6. A buckle 11 is provided on the outer end face of the sealing plate 10. A fixing block 12 is provided on the side wall of the box 6. A buckle 13 is hinged to the fixing block 12. The buckle 13 can be fastened to the buckle 11. When the sealing plate 10 is pushed into the box 6, the buckle 13 is fastened to the buckle 11, which can lock the sealing plate 10. When the sealing plate 10 is pulled open, the attapulgite in the box 6 can be unloaded and replaced.

[0022] like Figure 1-2The sliding adsorption drive device 4 includes a motor 14, which is fixed to the end face of the tank plate 2. The output end of the motor 14 is provided with a lead screw 15 and is threadedly connected to the support 3. A sliding rod 16 is fixed in the tank plate 2 on the other side and passes through the support 3. The sliding rod 16 is parallel to the lead screw 15. By rotating the lead screw 15, the support 3 can drive the box 6 to move, so that the attapulgite can be moved to adsorb phosphorus in the treatment tank 1, which is more efficient.

[0023] like Figure 1-2 The depth adjustment device 5 includes an electric push rod 17, which is fixed to the top wall of the bracket 3. The output end of the electric push rod 17 is connected to the housing 6. Two sets of guide rods 18 are fixed to the upper end of the housing 6 and located on both sides of the electric push rod 17. The guide rods 18 extend upward through the bracket 3 and are parallel to the extension and retraction direction of the electric push rod 17. The depth of the housing 6 can be adjusted by the electric push rod 17.

[0024] In practical use, the sealing plate 10 first seals the lower part of the tank 6, and attapulgite is added into the tank 6 through the feeding port 8. Then, by activating the electric push rod 17, the tank 6 moves down until all the attapulgite is submerged in the sewage in the treatment tank 1. The sewage can come into contact with the attapulgite through the mesh 7, thereby adsorbing the phosphorus element in the sewage.

[0025] During adsorption, by starting the motor 14, the lead screw 15 will drive the support 3 to slide in the tank plate 2. In this way, the attapulgite in the box 6 will move to adsorb the phosphorus element in the treatment tank 1, which greatly improves the adsorption efficiency.

[0026] When the attapulgite in the box 6 needs to be replaced, the box 6 is pulled above the treatment pool 1 by the electric push rod 17. A collection trough is placed below the box 6 and above the treatment pool 1. Then, the buckle plate 13 is released, the buckle ring 11 is pulled, and the sealing plate 10 is pulled horizontally. In this way, the attapulgite in the box 6 can fall into the collection trough, completing the collection of the attapulgite. Then, new attapulgite is added through the feeding port 8.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
