Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and specifically relates to a wastewater treatment device for pig farming. Background Technology

[0002] Wastewater generated in pig farms needs to be pre-treated using wastewater treatment equipment.

[0003] For example, Chinese patent CN215855511U discloses a wastewater treatment device for a pig farm, which includes a body, a rotating motor and a medicine storage tank. Supports are installed at the four corners of the lower end of the body, the rotating motor is installed in the middle of the upper end of the body, and a PLC controller is installed on the upper end of the rotating motor.

[0004] While the aforementioned patent addresses the issue of enabling wastewater treatment devices to perform automatic dosing, allowing them to replace manual laborers and thus reduce workload and improve efficiency, the device still has some shortcomings that require improvement. Specifically, the injection pipe lacks a structure to intercept debris such as feces and straw. These debris not only easily clog subsequent treatment pipes, affecting the continuity of the wastewater treatment process, but also cause the stirring rod to frequently become entangled in debris, exacerbating equipment wear, interfering with normal stirring operations, reducing mixing efficiency, and ultimately affecting the overall treatment effect.

[0023] Example

[0024] refer to Figures 1 to 5 This embodiment describes a wastewater treatment device for pig farming, comprising a treatment tank 1, a tank cover 2 at the top of the treatment tank 1, an injection pipe 7 fixedly connected to one side of the tank cover 2, a mesh grid 9 fixedly connected to one side of the inside of the injection pipe 7, a material guide hole 8 on one side of the injection pipe 7, a material guide hole 8 extending from one side of the mesh grid 9, a cleaning component 10 on one side of the injection pipe 7, a collection box 12 fixedly connected to one side of the injection pipe 7, a mesh grid 9 located above the collection box 12, a weighing component 13 located below the collection box 12, a medicine storage tank 3 fixedly connected to one side of the treatment tank 1 and the medicine storage tank 3 fixedly connected to one side of the tank cover 2, a stirring frame 16 fixedly connected to the output end of the motor 15, the stirring frame 16 being rotatably connected inside the treatment tank 1, and a liquid level sensor 6 fixedly connected to the bottom end of the tank cover 2.

[0025] refer to Figure 1-2 The top of the medicine storage tank 3 is fixedly connected to a medicine injection valve 4, and the bottom of the medicine storage tank 3 is fixedly connected to an electric metering valve 5. The medicine enters the medicine storage tank 3 through the medicine injection valve 4. The amount of wastewater in the treatment tank 1 is detected by the liquid level sensor 6. Then, the electric metering valve 5 can be controlled to dispense a certain amount of medicine according to the set ratio value. This is a conventional setting in the prior art, and the specific principle will not be repeated here.

[0026] refer to Figure 1 , Figure 3 , Figure 5 The cleaning component 10 includes a mounting base 102, which is slidably connected inside the injection pipe 7. A pusher block 103 is connected to the bottom end of the mounting base 102. One side of the pusher block 103 is in contact with one side of the mesh grid 9. An electric push rod 101 is fixedly connected to one side of the injection pipe 7. One side of the electric push rod 101 is fixedly connected to one side of the pusher block 103. Springs 104 are fixedly connected to both sides of the bottom end of the mounting base 102. One side of the spring 104 is fixedly connected to one side of the pusher block 103. By setting the cleaning component 10, the electric push rod 101 drives the mounting base 102 to move, and the mounting base 102 drives the pusher block 103 to move on the mesh grid 9. This can push the waste material on the mesh grid 9 out of the injection pipe 7, avoiding blockage on the mesh grid 9. By setting the springs 104, the pusher block 103 can better contact the mesh grid 9, facilitating the pushing operation.

[0027] refer to Figure 5 The top of the pusher block 103 is fixedly connected to a sleeve 105 inside the spring 104. A slide rod 106 is slidably connected inside the sleeve 105. One side of the slide rod 106 is fixedly connected to one side of the mounting base 102. By setting the sleeve 105 and the slide rod 106, the deformation of the spring 104 is stabilized, avoiding large displacement that would affect the operation of the pusher block 103.

[0028] refer to Figure 4 The weighing assembly 13 includes a weighing device 131, which is fixedly connected to the injection pipe 7 located below the collection box 12. A display screen 132 is fixedly connected to one side of the weighing device 131, and a placement plate 133 is fixedly connected to the upper side of the weighing device 131. The collection box 12 is placed on the placement plate 133. By setting the weighing assembly 13, a weighing sensor is provided inside the weighing device 131. The collection box 12 is placed on the placement plate 133. As debris continuously enters the collection box 12, the weight displayed on the display screen 132 also changes. After the staff observes that the set value has been reached, it is convenient to remove the collection box 12 and empty the debris inside.

[0029] refer to Figure 4 The top two sides of the placement plate 133 are provided with sliding grooves 134, and a slider 135 is slidably connected inside the sliding groove 134. One side of the slider 135 is fixedly connected to one side of the collection box 12. By setting the sliding grooves 134 and the slider 135, it is easy to install the collection box 12 on the placement plate 133.

[0030] Operating principle and advantages: Wastewater from pig farming, containing manure, straw, and other debris, is introduced into the treatment tank 1 through the injection pipe 7. The mesh screen 9 inside the injection pipe 7 intercepts the debris in the wastewater. The debris is blocked at the mesh screen 9, while the wastewater passes through the mesh screen 9 into the treatment tank 1. As debris accumulates on the mesh screen 9, the electric push rod 101 is activated, causing the mounting base 102 to slide within the injection pipe 7. The mounting base 102, connected to the push block 103 via spring 104, adheres to the mesh screen 9, pushing the debris off the mesh screen 9 during movement. The debris falls into the collection box 12 through the guide hole 8. The liquid level sensor 6 monitors the wastewater volume in the treatment tank 1 in real time and feeds the data back to the control system. The control system, based on a pre-set ratio, controls the electric metering valve 5 to open, allowing... The reagent in the storage tank 3 is injected into the treatment tank 1 according to the prescribed amount through the electric metering valve 5. At the same time, the motor 15 on the tank cover 2 is started, and its output end drives the stirring frame 16 to rotate inside the treatment tank 1, so as to fully stir and mix the wastewater and reagent to achieve a good treatment effect. The collection box 12 is placed on the placement plate 133 of the weighing component 13. The slider 135 on the placement plate 133 cooperates with the slide groove 134 to facilitate the installation and positioning of the collection box 12. The weighing sensor in the weighing device 131 monitors the weight of the debris in the collection box 12 in real time and displays it on the display screen 132. When the weight displayed on the display screen 132 reaches the set value, the staff can remove the collection box 12, pour out the debris inside for subsequent processing, and then reinstall the collection box 12 back on the placement plate 133 after cleaning.
