Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a sedimentation rotary slag removal and slag collection device. Background Art

[0002] Oily residue wastewater is wastewater containing oil and solid residue. The source and state of oily substances Oily substances may exist in sewage in various states. It may be free oil droplets of different sizes. Larger oil droplets can be separated from sewage by gravity separation, while smaller oil droplets may form emulsified oil, which requires special treatment methods to remove. The composition and source of solid residue Solid residue is the so-called "oil residue", which contains a variety of components, including mineral particles and organic solids. In addition, metal debris and fiber impurities generated in some industrial production processes may also be mixed in the oil residue.

[0003] The harm of oily residue wastewater to the environment is very serious. When oily residue wastewater enters the water body, the oil substance will form an oil film on the water surface. This oil film will hinder the oxygen exchange between the water body and the atmosphere, resulting in a decrease in the dissolved oxygen content in the water body, affecting the respiration of aquatic organisms. At the same time, some toxic and harmful substances in the oil residue (such as heavy metals, polycyclic aromatic hydrocarbons, etc.) may accumulate in the water body and sediment, and cause harm to higher organisms through the enrichment of the food chain.

[0004] In addition, oil residue will clog the pipes and filters of sewage treatment equipment. Existing oily residue sewage is usually treated by physical, chemical, biological and other methods. Among them, physical treatment is a low-cost treatment method and is widely used. Its advantages are large treatment volume and low cost. It is widely used in the primary treatment of oily sewage. However, its disadvantages are poor water quality after treatment. It can only remove floating oil with larger particles and unstable dispersed oil, and has limited effect on the removal of emulsified oil and dissolved oil. Moreover, the equipment occupies a large area and has a low degree of automation, and cannot achieve continuous sewage treatment.

[0005] Tar residue usually contains a variety of toxic chemicals, which have potential risks of being carcinogenic, mutagenic and teratogenic. There are many hazards in the manual cleaning of tar residue, including exposure to toxic substances such as polycyclic aromatic hydrocarbons, benzene, etc., which may cause cancer, respiratory diseases and skin damage; high temperature and flammability make the cleaning process subject to the risk of burns and fire; at the same time, mechanical injuries may occur during the cleaning process, high labor intensity may lead to musculoskeletal injuries, and psychological stress from long-term work. In addition, air pollution and improper cleaning may pollute the environment and further affect the ecology and public health. Taking protective measures can effectively reduce these risks. Generally, manual cleaning of tar residue is a dangerous job, which may cause many hazards to the health and safety of the cleaning personnel;

[0006] Therefore, the present invention aims to provide a sedimentation rotary slag removal and slag collection device, based on the idea of ​​letting machines do what they can do in high-risk industries. Solve the risk of manual operation in high-risk industries, and replace manual labor with machines. The high degree of automation can replace traditional manual slag digging operations, which can significantly improve safety, reduce the risk of work-related injuries, improve production efficiency and accuracy, reduce long-term costs, improve the working environment, reduce labor intensity, and optimize the production process through data collection and analysis. This not only helps to protect the health of workers and reduce resource waste, but also promotes the industry to develop in the direction of intelligence and automation, and promotes sustainable development. Summary of the invention

[0007] In view of the shortcomings of the prior art, the present invention provides a sedimentation rotating slag removal and slag collection device, which solves the problems of the existing oily residue wastewater treatment equipment occupying a large area, having a low degree of automation and being unable to achieve continuous wastewater treatment, as well as solving the risks of manual operation in high-risk industries.

[0012] The grid mechanism is arranged in the gap between the collecting mechanism and the outer barrel. It is used to transport the large particles deposited in the outer barrel to the upper part of the collecting mechanism through rotation. The external motor drives the grid mechanism to rotate and the large particles fall naturally into the collecting mechanism by its own gravity. The large particles inside are transported to the designated fixed solid waste collection point through the spiral auger.

[0015] Preferably, the overflow outlet at the front of the outer barrel is a water outlet overflow outlet, and the overflow outlet in the closing mechanism at the rear of the outer barrel is a sewage inlet.

[0016] Preferably, the outer barrel and the inner barrel are supported by supporting partitions, and the inner barrel and the outer barrel are coaxial.

[0017] Preferably, the collecting mechanism comprises an inner barrel, and a tar residue collecting groove for receiving large particles of matter is provided on the upper portion of the inner barrel.

[0018] Preferably, a plurality of supporting baffles are equidistantly fixedly installed on the lower part of the inner barrel, the bottom of the supporting baffles is fixedly connected to the inside of the outer barrel, and the inner barrel is fixedly installed on the inner wall of the outer barrel through a plurality of supporting blocks.

[0019] Preferably, the grille mechanism comprises two rotating end plates and a rotating shaft installed between two closing mechanisms, and the two rotating end plates are connected by a connecting long plate.

[0023] 1. The present invention forms a complete and efficient treatment system through the coordinated operation of the outer barrel, the closing mechanism, the collecting mechanism and the grid mechanism. The various components have clear division of labor, which ensures that the purification process of oily residue wastewater is carried out in an orderly manner. At the same time, the sewage inflow path is strictly controlled to allow the oily residue wastewater to enter the treatment link stably, standardize the discharge channel of the treated clean water, maintain the orderly operation of the water flow inside the device, and realize the continuous treatment of oily residue wastewater.

[0024] 2. The present invention uses the lower end support baffle to effectively intercept large particles in the liquid, allowing them to settle statically, laying a solid foundation for subsequent slag removal, efficiently separating large particles of impurities, and improving the initial sewage purification effect. At the same time, the grid mechanism uses the rotation effect and gravity to continuously transport the deposited large particles to the tar residue collection tank, realizing an automated rotary slag removal process. The cyclic operation can stably and continuously purify sewage with high work efficiency.

[0025] 3. When there is excessive accumulation of large particles in the tar residue collection tank, the tar residue is cleaned and transported to the designated solid waste treatment point with the help of a spiral auger. It is simple to operate and easy to clean, ensuring the sustainable operation of the device and facilitating the long-term treatment of oil residue-containing wastewater.

[0036] Please refer to the attached Figure 1 -Attached Figure 8 The embodiment of the present invention provides a sedimentation rotary slag removal and slag collection device, comprising:

[0037] The outer barrel 1 has flanges fixedly mounted at both the front and rear ends of the outer barrel 1, which provide a stable interface for subsequent component connections and ensure the overall structural strength and sealing of the device;

[0038] Please refer to the attached Figure 3 -Attached Figure 4There are two closing mechanisms 2, which are respectively connected to the flanges at both ends of the outer barrel 1 to achieve the closure of both ends of the outer barrel 1. It includes a flange cover 201, which is tightly connected to the end flange of the outer barrel 1. A bearing pressure cover 203 is fixedly installed in the middle. A rotating bearing 204 is installed in the bearing pressure cover 203 to ensure the smooth rotation of related components. An overflow outlet 202 is arranged on one side of the middle of the flange cover 201. The overflow outlet 202 at the front of the outer barrel 1 is used as a water overflow outlet, and the overflow outlet 202 of the rear closing mechanism 2 is a sewage inlet, each of which performs its function to guide the water flow in and out.

[0039] Please see attached Figure 5 -Attached Figure 7 The collecting mechanism 3 is arranged inside the outer barrel 1 and is used to block and keep large particles in the liquid. The collecting mechanism 3 includes an inner barrel 301. The upper part of the inner barrel 301 is provided with a tar residue collecting tank 302 for receiving large particles. A spiral auger 305 is arranged in the tank. The tail end of the spiral auger 305 is connected with a flange, which is connected to the solid waste collection device through the flange.

[0040] It is convenient to clean the materials in the collection tank regularly.

[0041] A plurality of support baffles 303 are fixedly installed at equal intervals at the lower part of the inner barrel 301 , the bottom of the support baffles 303 is fixedly connected to the inside of the outer barrel 1 , and the inner barrel 301 is fixedly installed on the inner wall of the outer barrel 1 through a plurality of support blocks 304 .

[0042] Please see attached Figure 8 The grid mechanism 4 is arranged in the gap between the collecting mechanism 3 and the outer barrel 1, and is used to transport the large particles to the upper part of the collecting mechanism 3 by relying on gravity through rotation.

[0043] The grid mechanism 4 includes two rotating end plates 401 and a rotating shaft 403 installed between the two closing mechanisms 2 . The two rotating end plates 401 are connected by a connecting long plate 402 .

[0044] The rotating shaft 403 passes through one side of the two rotating end plates 401 in sequence, and a plurality of rotating grilles 404 are fixedly installed at equal intervals on one side of the connecting long plate 402 .

[0045] Both sides of the outer wall of the rotating shaft 403 are respectively connected to the middle of the rotating bearings 204 on both sides, and can be connected to the rotating shaft 403 through an external motor to drive it to rotate.

[0046] Working principle: In actual use, this device mainly includes the following steps:

[0047] The first step is the entry of oily residue-containing sewage: In the present invention, both ends of the outer barrel 1 are equipped with a closing mechanism 2, which is mainly used to close the front and rear openings of the outer barrel 1. The overflow opening 202 in the front closing mechanism 2 is the water outlet overflow opening, and the overflow opening 202 in the rear closing mechanism 2 is the sewage inlet. The sewage first enters the collection mechanism 3 through the sewage inlet to start the sewage treatment;

[0048] Step 2: filtering and blocking large particles: large particles in the liquid are blocked and allowed to stand still by the support baffle 303 at the lower end of the inner barrel 301, and the large particles in the liquid are deposited in the rotating grid 404 inside the grid mechanism 4;

[0049] Step 3, rotary slag removal: After the grid mechanism 4 rotates to the upper position of the inner barrel 301, under the action of gravity, the large particles brought out from the rotating grid 404 inside the grid mechanism 4 fall into the tar residue collection tank 302 at the upper part of the inner barrel 301, thus completing a rotary slag removal process, and then repeat the above steps.

[0050] When there is too much large particle matter in the tar slag collecting tank 302 , the large particle matter in the tar slag collecting tank 302 can be discharged to a designated solid waste treatment point through the spiral auger 305 .

[0051] The present invention uses the lower end support baffle 303 to effectively intercept large particles in the liquid, allowing them to settle and lay a solid foundation for subsequent slag removal, efficiently separate large particles of impurities, and improve the initial sewage purification effect. At the same time, by utilizing the rotation of the grid mechanism 4 and the coordination of gravity, the deposited large particles are continuously transported to the tar residue collection tank 302, realizing an automated rotary slag removal process. The cyclic operation can stably and continuously purify sewage with high work efficiency.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
