Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, and in particular to a sewage mixing and treatment tank for sewage treatment. Background Technology

[0002] Manure treatment is a crucial link in environmental protection and resource recycling. Whether it's the large quantities of livestock and poultry manure generated in the livestock industry or household waste, improper treatment can cause serious pollution to soil, water, and air. As one of the core pieces of equipment in manure treatment, the manure mixing tank's main function is to thoroughly mix manure with treatment agents, achieving the harmless treatment and resource utilization of manure through chemical reactions or biodegradation.

[0003] Currently, there are still some shortcomings in the use of sewage mixing tanks on the market. In terms of chemical spraying, traditional spraying devices are mostly fixed structures with limited spraying range, resulting in the inability of the chemical to evenly cover all the sewage in the tank. Some areas have excessively high chemical concentrations while others have insufficient concentrations, affecting the sewage treatment effect. At the same time, the installation and disassembly of chemical spraying components are relatively cumbersome, making it inconvenient for later maintenance and cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a manure mixing and treatment tank for manure treatment, which solves the problem that traditional spraying devices in the prior art are mostly fixed structures with limited spraying range, resulting in the inability of the agent to evenly cover all the manure in the tank, and the agent concentration being too high in some areas and too low in others, thus affecting the manure treatment effect.

[0005] To achieve the above objectives, this utility model provides a sewage mixing and treatment tank for sewage treatment, comprising a tank body, an agent spraying assembly disposed inside the side wall of the tank body; a stirring assembly disposed between the inner walls of the tank body; the agent spraying assembly includes an installation groove, the installation groove being opened on both sides of the top of the tank body, a horizontal lead screw rotatably connected between the inner walls of the installation groove, a slider threadedly connected to the outer wall of the horizontal lead screw, a limiting slide rod fixedly connected between the inner walls of the other installation groove, a slider slidably connected to the outer wall of the limiting slide rod, a sleeve fixedly connected to the top of the slider, an insert rod inserted into the inside of the sleeve, a horizontal plate fixedly connected to the top of the two insert rods, lower convex plates fixedly connected to the bottom ends of the horizontal plate, an assembly tube fixedly connected between the two lower convex plates, a first servo motor fixedly connected to one side of the tank body, and the output shaft of the first servo motor fixedly connected to one end of the horizontal lead screw.

[0006] The assembly tube has a nozzle fixedly connected to the bottom of its outer wall, and the nozzles are arranged in an array along the direction of the assembly tube.

[0007] The outer wall of the assembled tube is fixedly connected to a connecting pipe, which is connected to an external drug infusion pipeline.

[0008] The agent spraying assembly also includes a mounting box, which is fixedly connected to one side of one of the sleeve blocks. A combination block is slidably connected between the inner walls of the mounting box, and a pin is fixedly connected to one side of the combination block. The pin passes through one side wall of the sleeve block and is inserted into the inside of the insert rod.

[0009] A pull rod is fixedly connected to the other side of the assembly block, the pull rod passes through one side of the mounting box, and a spring is also fixedly connected to the other side of the assembly block, one end of the spring being fixedly connected to one side of the inner wall of the mounting box.

[0010] The slider is rectangular in shape and is slidably connected to the inner wall of the mounting groove. A roller is fixedly connected to the bottom of the slider and makes rolling contact with the inner bottom of the mounting groove.

[0011] The stirring assembly includes two rotating shafts, which are rotatably connected to the inner wall of the tank and arranged parallel to each other. Stirring rods are fixedly connected to the outer wall of the rotating shafts. The stirring rods are arranged in groups of three in a circumferential pattern, and each group is arranged in an array along the direction of the rotating shaft. A worm gear is fixedly connected to one end of each of the two rotating shafts.

[0012] The pool body is fixedly connected to a protective box on one side. A worm gear is rotatably connected between the inner walls of the protective box. The worm gear is located between and meshes with two worm wheels, which are also located inside the protective box. A second servo motor is fixedly connected to the top of the protective box. The output shaft of the second servo motor is fixedly connected to one end of the worm gear.

[0013] Beneficial effects Compared with existing technologies, it has the following advantages: 1. In this utility model, a movable agent spraying component is provided. A first servo motor drives a horizontal lead screw to rotate, causing the slider and assembly tube to reciprocate along the top of the tank. Combined with an array of atomizing nozzles, this achieves all-around uniform spraying of the agent, effectively solving the problems of limited coverage and uneven agent distribution in traditional fixed spraying devices. This ensures consistent agent concentration in all areas of the sewage, improving treatment efficiency. The agent spraying component uses a plug-in connection between a rod and a sleeve block, achieving quick fixing via a pin and spring. Pulling the rod releases the fixation and completes disassembly. The structure is simple and easy to operate, significantly reducing the difficulty and workload of subsequent maintenance and cleaning, and improving the ease of use of the equipment.

[0014] 2. In this invention, the mixing assembly employs a dual-shaft counter-rotating design, coupled with three sets of circumferentially distributed and staggered mixing rods, increasing the mixing contact area and mixing force. This enables rapid and thorough mixing of manure and chemicals, accelerating the reaction process. Compared to traditional single-shaft mixing structures, the mixing efficiency and mixing uniformity are significantly improved, shortening the manure treatment cycle. The protective box seals and protects the worm gear, worm shaft, and other transmission components, effectively preventing manure corrosion and debris from entering the meshing area, ensuring the operational stability of the transmission mechanism, reducing component wear, and further extending the maintenance cycle and service life of the mixing assembly.

[0020] Reference Figure 1 , Figure 3 In one aspect of this embodiment, the stirring assembly 3 includes two rotating shafts 31, both rotatably connected between the inner walls of the tank body 1 and arranged parallel to each other. The rotating shafts 31 are made of stainless steel to improve corrosion resistance. Stirring rods 32 are fixedly connected to the outer walls of the rotating shafts 31. The stirring rods 32 are made of high-strength alloy material, and are arranged in groups of three in a circumferential pattern, with each group arranged in an array along the direction of the rotating shafts 31. The two groups of stirring rods 32 are staggered to improve the stirring effect. Worm gears 33 are fixedly connected to one end of each of the two rotating shafts 31, and the worm gears 33 are coaxially arranged with the rotating shafts 31. A protective box 36 is fixedly connected to one side of the tank body 1. The protective box 36 has a sealed structure and is filled with grease. A worm gear 34 is rotatably connected between the inner walls of the protective box 36. The worm gear 34 is located between and meshes with the two worm gears 33, and the rotation of the worm gear 34 can simultaneously drive the two worm gears 33 to rotate in opposite directions. Both worm gears 33 are located inside the protective housing 36, which prevents feces and debris from entering the meshing point between the worm gears 33 and the worm 34, thus avoiding damage to the transmission mechanism. A second servo motor 35 is fixedly connected to the top of the protective housing 36, and the output shaft of the second servo motor 35 is fixedly connected to one end of the worm 34, providing power for the rotation of the worm 34.

[0021] Working Principle: When the sewage treatment tank is in operation, the sewage to be treated is first introduced into the tank body 1. Then, the external chemical delivery pipeline is connected to the connecting pipe 212. The chemical enters the assembly pipe 210 through the connecting pipe 212 and is atomized by the array of nozzles 211 before being sprayed onto the sewage in the tank body 1. The slider 24, through the sleeve block 26 and the insert rod 27, drives the horizontal plate 28, the lower convex plate 29, and the assembly pipe 210 to form a whole. Then, the first servo motor 218 is activated. The output shaft of the first servo motor 218 drives the horizontal lead screw 22 to rotate. Since the horizontal lead screw 22 is threadedly connected to one slider 24, and the other slider 24 is slidably engaged with the limiting slide rod 23, the rotation of the horizontal lead screw 22 causes the two sliders 24 to move synchronously horizontally along the mounting groove 21. The rollers 25 at the bottom of the slider 24 roll within the mounting groove 21, reducing movement resistance and making the slider 24 move more smoothly. The slider 24 drives the horizontal plate 28, the lower convex plate 29, and the assembly tube 210 to move synchronously via the sleeve block 26 and the insert rod 27, realizing the reciprocating movement of the agent spraying component 2 at the top of the tank 1, ensuring that the agent is evenly sprayed onto the feces and sludge in various areas of the tank. Simultaneously with the agent spraying, the second servo motor 35 is activated. The output shaft of the second servo motor 35 drives the worm gear 34 to rotate. The worm gear 34 meshes with two worm wheels 33, and due to the rotation direction of the worm gear 34, the two worm wheels 33 drive the corresponding rotating shaft 31 to rotate in opposite directions. When the rotating shaft 31 rotates, the stirring rods 32 on its outer wall rotate synchronously. The two sets of staggered stirring rods 32 thoroughly stir the feces and sludge and the agent in the tank 1, ensuring uniform mixing of the feces and sludge, accelerating the chemical reaction or biodegradation process, and improving the efficiency of feces and sludge treatment. When maintenance or cleaning of the pesticide spraying assembly 2 is required, pull rod 217. Pull rod 217 moves assembly block 214 into mounting box 213. Assembly block 214 compresses spring 216, simultaneously pulling pin 215 out of the insert rod 27, releasing the fixed relationship between insert rod 27 and sleeve block 26. Then, lift horizontal plate 28 upward to pull insert rod 27 out of sleeve block 26, achieving quick disassembly of pesticide spraying assembly 2. After maintenance and cleaning, insert rod 27 is inserted into sleeve block 26, pull rod 217 is released, spring 216 returns to its original position, pushing assembly block 214 and pin 215 to move. Pin 215 is re-inserted into insert rod 27, completing assembly and fixation. Protective box 36 effectively protects transmission components such as worm gear 33 and worm 34, preventing corrosion from fecal matter and interference from debris, ensuring long-term stable operation of mixing assembly 3.
