Description

Technical Field

[0001] This utility model relates to the field of waste treatment equipment, and in particular to an organic slurry impurity removal device. Background Technology

[0002] Currently, anaerobic digestion technology accounts for 76.1% of organic waste treatment technologies in my country. Anaerobic digestion refers to the digestion technology in which organic matter is decomposed into CH4, CO2, H2O, and H2S by facultative and anaerobic bacteria under anaerobic conditions. When using anaerobic digestion technology, organic waste is centrally processed in a centralized anaerobic digestion facility. This leads to the following problems: due to the dispersed collection sources of organic waste, it may contain solid waste such as tableware fragments, bones, and sand, which can easily cause equipment failure in the pretreatment system and may even require manual sorting. Existing organic slurry treatment uses impurity removal devices, but these devices are relatively complex and have low impurity removal efficiency. Utility Model Content

[0003] The present invention aims to at least partially solve the technical problems in the aforementioned technologies. Therefore, the purpose of this invention is to provide an organic slurry impurity removal device, which has a simple structure and high separation efficiency.

[0004] To achieve the above objectives, an embodiment of this utility model provides a waste disposal device, comprising: a base and a device body disposed on the base;

[0005] The device body has a tank for containing slurry and a good slurry tank for containing good slurry. The tank is equipped with a stirring element, a feed inlet, a discharge outlet, a heavy slag outlet, and a light slag outlet. The stirring element is rotatably configured to drive the slurry in the tank to perform centrifugal rotation. The feed inlet is connected to a pumping device to pump the slurry into the tank. The discharge outlet is equipped with a sieve plate and connected to the good slurry tank. When the pumping device continuously pumps, it can cause the filtered good slurry to flow into the good slurry tank. The heavy slag outlet is located away from the rotation axis of the stirring element, and the light slag outlet is located close to the rotation axis of the stirring element. The inlet of the external pipe of the feed inlet, as well as the outlet of the external pipes of the light slag outlet and the good slurry tank, are all located above the tank body. The external pipes of the light slag outlet and the good slurry outlet are equipped with valves that can adjust the discharge size.

[0006] An organic slurry impurity removal device according to an embodiment of this utility model separates heavy and light residues in the slurry through centrifugal force, and discharges them through corresponding heavy and light residue outlets. The slurry is then filtered through a screen plate at the discharge port to produce good slurry, which enters a good slurry tank. The inlet of the external pipe connecting to the feed port, and the outlets of the external pipes connecting to the light residue outlet and the good slurry tank, are all higher than the tank body, creating a pressure difference between the feed port and the light residue outlet, and between the feed port and the good slurry outlet. Valves on the feed port and the good slurry outlet control the internal pressure difference within the tank, thereby ensuring smooth rotation of the slurry within the tank and guaranteeing the discharge efficiency of the good slurry and the separation efficiency of the heavy and light residues. This organic slurry impurity removal device has a simple structure and high separation efficiency.

[0007] In addition, the organic slurry impurity removal device proposed in the above embodiments of this utility model may also have the following additional technical features:

[0008] Optionally, the tank is cylindrical, with one outer end of the tank recessed along the interior of the tank, and the light slag outlet is located in the recess.

[0009] Furthermore, the light slag inlet is located at the center of the concave area, and the heavy slag inlet is located at the tangent of the outer circular surface of the tank.

[0010] Furthermore, the trough is installed horizontally on the base.

[0011] Optionally, the external pipes of the feed inlet and the external pipes of the slurry outlet are equipped with pressure detection devices that can detect the pressure inside the pipes.

[0012] Optionally, the bottom of the tank is provided with a drain outlet.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] The following is for reference. Figures 1-2 The present invention describes in detail the implementation of an organic slurry impurity removal device according to an embodiment of the present invention.

[0025] An organic slurry impurity removal device according to an embodiment of the present invention includes: a base 1 and a device body 2 disposed on the base 1.

[0026] Specifically, the device comprises a base 1 and a device body 2 mounted on the base 1. The device body 2 has a tank 21 for containing slurry and a good slurry tank 22 for containing good slurry. The tank 21 is equipped with a stirring element 211, a feed inlet 212, a discharge outlet 213, a heavy slag outlet 214, and a light slag outlet 215. The stirring element 211 is rotatably mounted to drive the slurry in the tank 21 to perform centrifugal rotation. The feed inlet 212 is connected to a pumping device to pump the slurry into the tank 21. A sieve plate 21 is provided at the discharge outlet 213. 6. Connect to the good slurry tank 22. When the pumping device continuously pumps, the filtered good liquid can flow into the good slurry tank 22. The heavy slag port 214 is set away from the rotation axis of the agitator 211, and the light slag port 215 is set close to the rotation axis of the agitator 211. The inlet of the external pipe of the feed port 212, as well as the outlet of the external pipe of the light slag port 215 and the good slurry tank 22, are all set higher than the tank body 21. The external pipes of the light slag port 215 and the good slurry port 221 are equipped with valves that can adjust the discharge size.

[0027] In other words, the overall organic slurry impurity removal device pumps the slurry into the tank 21 through the inlet 212. The agitator 211 inside the tank 21 rotates and agitates the slurry, causing it to undergo centrifugal motion. Due to the weight difference, the heavy and light slag in the slurry are dispersed by centrifugal force, causing the heavy slag to collect at the heavy slag inlet 214, which is farther from the rotation center of the agitator 211, while the light slag collects at the light slag inlet 215, which is closer to the rotation center of the agitator 211. The slurry is then pumped in... The slurry filtered through the sieve plate 216 at the discharge port 213 is delivered to the good slurry tank 22. Since the inlet of the external pipe at the feed inlet 212, as well as the outlets of the light slag outlet 215 and the good slurry tank 22, are all higher than the slurry body 21, adjusting the opening and closing of the valves on the external pipes of the light slag outlet 215 and the good slurry outlet 221 can adjust the pressure inside the slurry body 21. This ensures the rotational movement of the slurry within the slurry body 21 and the discharge of the good slurry, thereby improving the separation efficiency of light and heavy slag in the slurry. A valve can be installed on the external pipe at the feed inlet 212, and the agitator 211 is equipped with blades, which can be long, curved blades.

[0028] Optionally, the tank 21 is cylindrical, with one outer end of the tank 21 recessed along its interior 217. A light slag outlet 215 is located within this recess. Understandably, the cylindrical shape of the tank 21 and the recess 217 facilitate better coordination with the rotation of the agitator 211, enabling the slurry to quickly rotate and separate from the heavy slag. The light slag outlet 215's location within the recess 217 increases the contact area between the recess and the light slag, promoting the collection and discharge of the light slag. It also guides the light slag to the outlet 215, improving discharge efficiency. The agitator 211 can extend from the opposite end of the recess 217 towards the recess 217, facilitating thorough slurry refinement.

[0029] Furthermore, the light slag outlet 215 is located at the center of the recess 217, and the heavy slag outlet 214 is located at the tangent of the outer circular surface of the tank body 21. Understandably, by placing the light slag outlet 215 at the center of the recess 217 and the heavy slag outlet 214 at the tangent of the outer circular surface of the tank body 21, the distribution positions of the heavy and light slag after centrifugal motion can be better matched, thereby facilitating the collection and discharge of medium-heavy and light slag, and thus improving the impurity removal efficiency of the slurry. Valves are installed on the external pipes of both the light slag outlet 215 and the heavy slag outlet 214.

[0030] Furthermore, the tank 21 is installed horizontally on the base 1. Understandably, the horizontal arrangement of the tank 21 facilitates the flattening of the overall device, thereby reducing the space occupied by the entire device. It also prevents heavy and light slag from accumulating at the bottom, which would result in poor separation, as is the case with a vertical installation. The tank 21 can be connected to the base 1 at its midsection.

[0031] Optionally, both the external pipes of the feed inlet 212 and the external pipes of the good pulp outlet 221 are equipped with pressure detection elements 23 to detect the pressure inside the pipes. Understandably, the pressure detection elements 23 facilitate the observation of the pressure in the external pipes of the feed inlet 212 and the good pulp outlet 221, thereby facilitating the protection of the overall device operation. The pressure detection element 23 can be a pressure sensor or a pressure gauge.

[0032] Optionally, a drain port 218 is provided at the bottom of the tank 21. Understandably, the drain port 218 facilitates the discharge of substances other than heavy slag, light slag, and good liquid, thereby ensuring the operation of the entire unit. The external pipe of the drain port 218 is equipped with an automatic valve, facilitating switching between continuous and batch operation of the entire unit. When there is little light slag in the slurry, the valve of the drain port 218 can be closed to allow the light slag to be discharged from the drain port 218.

[0033] Optionally, a scraper is connected to the agitator 211, which rotates synchronously with the agitator 211 to scrape the sieve plate 216. Understandably, the scraper facilitates the removal of material adhering to or clogging the sieve plate 216, thus preventing clogging and ensuring the operation of the entire device. The agitator 211 can pass through the center of the sieve plate 216, which can be circular to allow for more thorough scraping by the rotating scraper.

[0034] Optionally, the sieve holes of the sieve plate 216 are arranged to gradually increase in size along its flow direction. Understandably, by arranging the sieve holes of the sieve plate 216 to gradually increase in size along its flow direction, it is easier to increase the speed at which the slurry passes through the sieve holes while ensuring the filtration effect of the sieve plate 216, thereby improving the filtration efficiency. The sieve holes can be stepped holes with varying diameters or conical holes.

[0035] Optionally, the system also includes a heavy slag tank 24, which is connected to a heavy slag inlet 214 to collect heavy slag and perform solid-liquid separation by rotation. The heavy slag tank 24 is also connected to a feed inlet 212 to return the separated slurry from the heavy slag to the feed inlet 212. Understandably, by setting up the heavy slag tank 24, the collected heavy slag can be rotated to separate the heavy slag from the slurry on it. The separated slurry is then returned to the feed inlet 212 and enters the tank 21 for further separation, thus achieving more thorough impurity removal from the slurry. The separated slurry can be pumped back into the tank 21, while the heavy slag separated from the slurry in the heavy slag tank 24 is rotated and discharged into the next stage of the process.

[0036] Optionally, the system also includes a drive assembly 25, which is connected to the agitator 211 to drive the agitator 211 to rotate. Understandably, connecting the agitator 211 to the drive assembly 25 facilitates the rotation of the agitator 211, thereby facilitating the rotational movement of the slurry within the tank 21. The drive assembly 25 may be a structure consisting of a motor, belt, and pulley.
