Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer production technology, and in particular to a wastewater treatment device for organic fertilizer production. Background Technology

[0002] Organic fertilizer is a type of fertilizer made primarily from organic matter such as plant and animal remains and excrement, which is fermented and decomposed. It is rich in organic matter and various nutrients, and can improve soil structure, enhance soil fertility, and promote crop growth.

[0003] In the process of organic fertilizer production, wastewater treatment often faces a thorny problem. This wastewater contains a large amount of large-particle solid impurities such as straw and residue, which need to be intercepted by the filters in the filtration device.

[0004] However, these filters are usually installed deep inside the filtration system. After long-term operation, the trapped solid impurities gradually accumulate on the surface of the filter, forming a thick layer of blockage. Over time, these deposits become increasingly dense, severely hindering the normal flow of wastewater and significantly reducing filtration efficiency.

[0005] What's more troublesome is that, because the filter is hidden, operators find it difficult to directly observe the blockage, often only discovering the problem when the system exhibits obvious abnormalities. At this point, cleaning becomes extremely difficult, requiring shutdown and disassembly of the equipment, impacting production efficiency and increasing maintenance costs. In high-temperature and high-humidity production environments, these organic impurities are also prone to fermentation and spoilage, producing odors and further deteriorating the working environment.

[0006] Chinese patent discloses a wastewater treatment device for organic fertilizer production (authorization announcement number CN222204824U). The patented technology mainly includes wastewater treatment equipment, a base, an inlet, an outlet, two fixing blocks, and four connecting blocks. The base is located at the bottom of the wastewater treatment equipment. The inlet is located on the right side of the front of the wastewater treatment equipment and is fixedly connected to the wastewater treatment equipment. The outlet is located on the left side of the front of the wastewater treatment equipment and is fixedly connected to the wastewater treatment equipment. The two fixing blocks are located on the front and rear sides of the wastewater treatment equipment, respectively, and are fixedly connected to the wastewater treatment equipment.

[0007] However, this patent still has shortcomings. During the production of organic fertilizer, a large amount of wastewater is generated, containing large particulate solid impurities. Typically, this wastewater is poured into a filtration device equipped with a filter screen to filter out these large particles. However, since the filter screen is located inside the filtration device, over time, these large particles accumulate on the screen, causing blockage and making cleaning difficult. Therefore, those skilled in the art have provided a wastewater treatment device for organic fertilizer production to solve the problems mentioned in the background section. Utility Model Content

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Example 1

[0042] Please see Figures 1-3 As shown, this embodiment is a wastewater treatment device for organic fertilizer production, including:

[0043] The tank assembly 100 includes a water tank 120, a groove 121 formed on the upper surface of the water tank 120, and a water trough 122 formed at the bottom of the inner wall of the groove 121;

[0044] The filter assembly 200 is located on one side of the housing assembly 100;

[0045] The filter assembly 200 includes a fixed plate 210 at the front and rear ends of one side of the water tank 120, a rotating shaft 220 rotatably connected to the fixed plate 210, a rotating plate 230 fixed to the rotating shaft 220, a mounting groove 231 opened on the upper surface of the rotating plate 230, and a filter screen 250 fixed to the inner wall of the mounting groove 231.

[0046] Four pillars 110 arranged in a rectangular array are fixed to the lower surface of the water tank 120;

[0047] A mounting hole 123 is provided on the lower surface of the water tank 120, and a pipe 130 is inserted into the mounting hole 123 and fixed therein;

[0048] The front end of the fixing plate 210 has a circular hole 211, and a motor 240 is fixed to the front end of the fixing plate 210. The rear end of the drive shaft of the motor 240 extends into the circular hole 211, and a rotating shaft 220 is fixed to the rear end of the drive shaft of the motor 240.

[0049] Motor 240 provides power for the rotation of shaft 220, rotating plate 230 and filter screen 250, so that rotating plate 230 and filter screen 250 can rotate as needed, making it easy to pour out the impurities accumulated on filter screen 250 and prevent filter screen 250 from becoming clogged after long-term use.

[0050] Use the filter component 200;

[0051] When wastewater from organic fertilizer production needs to be treated, the wastewater is poured into the water tank 122. When the wastewater passes through the filter screen 250, the filter screen 250 can filter out large solid impurities in the wastewater. The filtered wastewater enters the water tank 122 and is then discharged through the pipe 130. At the same time, after a long period of filtration, when large impurities accumulate on the filter screen 250, the motor 240 is started to rotate the rotating plate 230, and the impurities on the filter screen 250 are poured out. This achieves the effect of facilitating the removal of impurities from the filter screen 250 and preventing the accumulation and blockage of impurities on the filter screen 250 over a long period of time. Example 2

[0052] Please see Figure 4 As shown, and;

[0053] Cleaning component 300 is located on one side of housing component 100;

[0054] The cleaning component 300 includes a long plate 370 fixed to one side of the water tank 120, a long groove 372 formed on the upper surface of the long plate 370, a connecting block 360 inserted into the long groove 372, a movable plate 310 fixed to the upper surface of the connecting block 360, a mounting plate 330 fixed to the upper surface of the movable plate 310, and a brush 320 fixed to the upper surface of the mounting plate 330.

[0055] A threaded hole 361 is provided on one side of the connecting block 360, and a round hole 371 is provided on one side of the long plate 370. A motor 340 is fixed on one side of the long plate 370. One side of the drive shaft of the motor 340 extends into the round hole 371. A screw 350 is fixed on one side of the drive shaft of the motor 340. One side of the screw 350 passes through the threaded hole 361 and is threadedly connected.

[0056] The drive shaft fixing screw 350 of the motor 2 340 provides power for the rotation of the screw 350, so that the connecting block 360, the moving plate 310, the mounting plate 330 and the brush 320 can be moved as needed, and the brush 320 can clean the impurities adhering to the filter screen 250.

[0057] Motor 1 (240) and Motor 2 (340) are servo motors. The servo motor structure mainly consists of three parts: the motor body, the encoder, and the driver. The motor body typically uses a permanent magnet synchronous motor or a brushless DC motor. Its rotor is composed of permanent magnets, and the stator contains multi-phase windings. A rotating magnetic field is generated by precisely controlling the current, driving the rotor to rotate. The encoder is used to detect the rotor's position and speed in real time and feeds the signal back to the driver, forming a closed-loop control to ensure the motor accurately follows commands. The driver receives signals from the controller and, combined with the encoder feedback, adjusts the motor's current, voltage, and phase to achieve precise speed, torque, and position control.

[0058] The working principle of a servo motor is based on closed-loop feedback control. When the controller sends a motion command, the driver compares the actual position with the target value, calculates the error signal, and adjusts the output current through a PID algorithm to enable the motor to quickly and stably reach the target state.

[0059] The width of the long slot 372 on the upper surface of the long plate 370 matches the width of the connecting block 360.

[0060] Use the cleanup component 300;

[0061] After the rotating plate 230 and the filter screen 250 are rotated to the horizontal position, the motor 340 is started, which causes the screw 350 to rotate. The connecting block 360, the moving plate 310, the mounting plate 330 and the brush 320 can be moved as needed. The brush 320 can clean the impurities stuck on the filter screen 250, thus achieving the effect of facilitating the cleaning of the impurities stuck on the filter screen 250.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0063] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
