Description

Technical Field

[0001] This utility model mainly relates to the field of aquaculture wastewater treatment technology, specifically to a device for treating rice planting wastewater in rice-shrimp co-cultivation areas. Background Technology

[0002] Rice-crayfish co-cultivation is a highly efficient and ecological agricultural farming model that combines rice and crayfish farming, achieving "dual use of water and double harvest from one field." Under this model, in order to maintain a good water quality environment to meet the shared growth needs of rice and crayfish, and to meet environmental emission requirements, the wastewater discharged from the rice paddies needs to be treated regularly.

[0003] Currently, for the treatment of wastewater from rice-shrimp co-cultivation areas, physical filtration is usually a pretreatment or crucial step. It removes large suspended solids from the wastewater, reducing the load on subsequent biological treatment units, preventing clogging, and improving overall treatment efficiency. When wastewater passes through the filter, these impurities accumulate in large quantities on the filter surface and within the mesh within a short period. This drastically reduces the effective filtration area of ​​the filter and rapidly decreases its flow capacity. The filter often becomes saturated and clogged after a short period of operation, requiring frequent disassembly and cleaning, which in turn affects overall operating efficiency. Utility Model Content

[0004] 1. The technical problem to be solved by the utility model:

[0005] This utility model provides a wastewater treatment device for rice cultivation in rice-shrimp co-cultivation areas to solve the technical problems existing in the background art.

[0006] 2. Technical Solution:

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: a wastewater treatment device for rice planting in a rice-shrimp co-cultivation area, comprising a filter box, wherein an inclined filter plate is fixedly installed inside the filter box, a water inlet channel is provided at the upper inclined end of the filter plate at the top of the filter box, a residue outlet is provided at the lower inclined end of the filter plate on the side wall of the filter box, and an open collection box is provided at the residue outlet.

[0008] The filter box is equipped with a drive mechanism, which is connected to a connecting plate and drives it to reciprocate in a direction parallel to the surface of the filter plate. The bottom of the connecting plate is connected to a mounting plate through a telescopic mechanism. The telescopic mechanism extends and retracts in a direction perpendicular to the surface of the filter plate. A brush plate is detachably connected to the bottom of the mounting plate.

[0009] Furthermore, the driving mechanism includes a lead screw and a guide rod that are parallel to and symmetrically distributed on the surface of the filter plate.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "equipped with" 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 utility model according to the specific circumstances. Example

[0028] See attached document Figure 1-5 A wastewater treatment device for rice cultivation in a rice-shrimp co-cultivation area includes a filter box 1. An inclined filter plate 2 is fixedly installed inside the filter box 1. A water inlet channel 3 is provided at the top of the filter box 1 at the upper inclined end of the filter plate 2. A residue discharge outlet 4 is provided on the side wall of the filter box 1 at the lower inclined end of the filter plate 2. An open collection box 5 is provided at the residue discharge outlet 4. A drive mechanism 6 is provided inside the filter box 1. The drive mechanism 6 is connected to a connecting plate 7 and drives it to reciprocate in a direction parallel to the surface of the filter plate 2. A mounting plate 9 is connected to the bottom of the connecting plate 7 through a telescopic mechanism 8. The telescopic direction of the telescopic mechanism 8 is perpendicular to the surface of the filter plate 2. A brush plate 10 is detachably connected to the bottom of the mounting plate 9.

[0029] In this embodiment, after the wastewater enters the filter box 1 through the water inlet channel 3, it will fall on the upper inclined end of the filter plate 2 to filter impurities. As the impurities accumulate and are flushed by the wastewater, the impurities will slide down the filter plate 2 until they fall into the collection box 5 through the residue discharge outlet 4, thus saving the need for manual cleaning of impurities and greatly improving the overall work efficiency.

[0030] When the filter plate 2 becomes clogged due to prolonged use, the mounting plate 9 is first moved perpendicular to the surface of the filter plate 2 by the telescopic mechanism 8 until the brush plate 10 comes into contact with the surface of the filter plate 2. Then, the connecting plate 7 is moved reciprocally in a direction parallel to the surface of the filter plate 2 by the drive mechanism 6, and the brush plate 10 moves synchronously to clean the filter plate 2.

[0031] In the above embodiments, the wastewater filtered by the filter plate 2 is then pumped into existing wastewater treatment equipment such as sedimentation tank, aeration tank, and biological reactor until it meets the discharge standards.

[0032] The drive mechanism 6 includes a lead screw 601 and a guide rod 602 that are parallel to the surface of the filter plate 2 and symmetrically distributed. The lead screw 601 is rotatably connected to the side wall of the filter box 1. Its rod body passes through the threaded through groove 603 opened on the connecting plate 7 and is threadedly engaged with it. One end of the lead screw 601 extends to the outside of the filter box 1 and is fixedly installed with a handle 605. The guide rod 602 is fixedly connected to the filter box 1. Its rod body passes through the sliding through groove 604 opened on the connecting plate 7 and is slidably engaged with it.

[0033] In this embodiment, after the grip 605 drives the lead screw 601 to rotate, the connecting plate 7 can reciprocate along a direction parallel to the surface of the filter plate 2 through the sliding engagement of the sliding groove 604 and the guide rod 602, in conjunction with the threaded engagement of the lead screw 601 and the threaded groove 603.

[0034] Inside the filter box 1, there are two baffles 11 symmetrically fixed. The two baffles 11 are located directly above the lead screw 601 and the guide rod 602, respectively, and have a guide slope inclined towards the center line of the filter box 1 on their inner sides.

[0035] In this embodiment, the baffle 11 can block wastewater, preventing wastewater from falling directly onto the lead screw 601 and guide rod 602 and affecting their transmission effect. Both the lead screw 601 and guide rod 602 are made of corrosion-resistant materials, which can ensure their service life in humid environments.

[0036] The telescopic mechanism 8 includes an electric push rod 801 fixed at the bottom center of the connecting plate 7, and guide sleeves 802 symmetrically distributed on both sides of the electric push rod 801. The telescopic end of the electric push rod 801 and the axis of the guide sleeve 802 are both perpendicular to the surface of the filter plate 2. A sliding rod 803 that slides with the guide sleeve 802 is fixed on the top of the mounting plate 9.

[0037] In this embodiment, after the electric actuator 801 is activated, it can drive the mounting plate 9 to move in a direction perpendicular to the surface of the filter plate 2. Furthermore, the sliding engagement between the guide sleeve 802 and the sliding rod 803 makes the movement process more stable.

[0038] The bottom of the mounting plate 9 is fixed with several evenly distributed positioning blocks 901 along its length. A first positioning hole 902 is opened through the positioning block 901. The top of the brush plate 10 is provided with a corresponding insertion groove 1001 that fits with the positioning block 901. A second positioning hole 1002 corresponding to the first positioning hole 902 is opened on the side wall of the insertion groove 1001.

[0039] In this embodiment, after the positioning block 901 is inserted into the insertion slot 1001, the brush plate 10 is fixed by the locking screw 12 that passes through the first positioning hole 902 and the second positioning hole 1002.

[0040] The bottom of the positioning block 901 is provided with a first magnetic element 13, and the bottom of the insertion slot 1001 is provided with a second magnetic element 14 that magnetically engages with the first magnetic element 13.

[0041] In this embodiment, the first magnetic component 13 and the second magnetic component 14 constitute a magnetic pre-positioning assembly, which is used to maintain the temporary fixed state of the brush plate 10 and the mounting plate 9 before the locking screw 12 is assembled.

[0042] The above embodiments only illustrate a certain implementation of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present utility model, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent should be determined by the appended claims.

[0043] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art.
