Description

Technical Field

[0001] This utility model relates to the field of grinding oil filtration technology, specifically a grinding oil filtration machine based on a graded filtration and synergistic linkage composite system. Background Technology

[0002] During the production process of the grinding chip briquetting system, a large amount of highly polluted grinding oil is generated. This type of oil has prominent problems such as high solid content, small impurity particle size, high water content, and partial emulsification.

[0003] Existing conventional grinding oil filters typically employ a single filtration method, such as screen filtration or cartridge filtration. By allowing the sludge to flow through the filter medium, the pores of the medium intercept solid particulate impurities in the oil, achieving preliminary purification. However, this method has significant technical limitations, with insufficient filtration precision, failing to effectively remove tiny particulate impurities, and making it difficult to reduce the solid content of the oil. Consequently, the cleanliness of the treated oil does not meet the standards and cannot satisfy the requirements for recycling. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a grinding oil filter based on a graded filtration and synergistic linkage composite system, which solves the problems of high-pollution grinding oil with high solid content, moisture content, and fine impurities, as well as the insufficient precision of conventional filters and the need for frequent filter element replacement.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a grinding oil filter based on a graded filtration and synergistic linkage composite system, comprising: a primary filtration device, an intermediate treatment device fixedly connected to the top of the primary filtration device by bolts, a multi-stage precision filter fixedly connected to the top of the primary filtration device by bolts, a discharge device provided on the outer wall of the primary filtration device, the primary filtration device including filter paper, and a vacuum paper belt filter rotatably connected to the outer wall of the filter paper. The primary filtration device adopts a combination design of vacuum paper belt filter and low flow rate, high vacuum, which can efficiently intercept large particles and some small impurities by forming a deep filtration effect, significantly reducing the solid content of the oil.

[0006] Preferably, the intermediate treatment device includes a vacuum tank, which is an oil-gas separation type. The bottom end of the vacuum tank is fixedly connected to the top end of the vacuum paper tape filter by bolts. The intermediate treatment device achieves deep dehydration and degassing through the synergistic action of the vacuum tank, heater and vacuum pump, thus solving the problem of oil emulsification.

[0007] Preferably, the input end of the vacuum tank is fixedly connected to a heater via a pipe, and the output end of the vacuum tank is fixedly connected to a vacuum pump via a pipe.

[0008] Preferably, the bottom ends of the heater and vacuum pump are fixedly connected to the top end of the vacuum paper tape filter by bolts.

[0009] Preferably, the discharge device includes a speed reducer, and the discharge device also includes an automatic paper winding assembly. A slag cart is arranged below the automatic paper winding assembly. The cooperative design of the automatic paper winding assembly and the slag cart realizes automatic replacement of filter media and centralized collection of impurities, reducing manual cleaning costs.

[0010] Preferably, the outer wall of the reducer is fixedly connected to the end of the vacuum paper belt filter away from the filter paper, the outer wall of the automatic paper winding assembly is fixedly connected to the side wall of the vacuum paper belt filter, and the automatic paper winding assembly is located below the reducer. The linkage design of the reducer and the automatic paper winding assembly ensures that the filter material replacement and the filtration process are synchronized, avoids equipment downtime due to filter material blockage, and ensures continuous and stable operation.

[0011] Beneficial effects This invention provides a grinding oil filter based on a graded filtration and synergistic linkage composite system. It has the following beneficial effects: This invention utilizes a vacuum paper belt filter in conjunction with filter paper to achieve deep filtration through low flow rate and high vacuum, effectively removing large particulate impurities, significantly reducing solid content, lessening the load on subsequent processing, and extending the life of precision filter elements. The intermediate treatment unit, through the synergistic action of an oil-gas separation vacuum tank, heater, and vacuum pump, deeply dehydrates and degasses the oil, preventing emulsification and oxidation, and improving oil stability. Multi-stage precision filters ensure that the final oil cleanliness reaches NAS6 level, meeting the requirements of high-precision grinding. In the discharge device, the reducer and automatic paper winding assembly are linked, working with the slag cart to achieve automatic filter media replacement and impurity collection, reducing manual intervention. All devices are connected by bolts for easy disassembly and maintenance. The system has a high degree of automation, stable operation, reduced maintenance costs and energy consumption, conforms to the concept of green manufacturing, and significantly improves the recycling efficiency of grinding oil.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example Please see Figure 1-4 This utility model provides a technical solution: a grinding oil filter based on a graded filtration and synergistic linkage composite system, comprising: The primary filter device 1 is bolted to the top of the intermediate treatment device 2, which is bolted to the top of the multi-stage precision filter 3. The outer wall of the primary filter device 1 is equipped with a discharge device 4. The oil is initially filtered by the primary filter device 1, then processed by the intermediate treatment device 2, and then passed through the multi-stage precision filter 3 before being discharged from the discharge device 4. The oil that has undergone intermediate treatment then enters the multi-stage precision filter 3 to further remove residual fine impurities, ultimately outputting grinding oil with a cleanliness level of NAS6, meeting the requirements of high-precision grinding. The primary filtration device 1 includes filter paper 10, and a vacuum paper belt filter 11 is rotatably connected to the outer wall of the filter paper 10. The waste oil to be treated first enters the vacuum paper belt filter 11 of the primary filtration device 1. During the rotation of the filter paper 10 on the outer wall, the low flow rate reduces the impurity permeability, while the high vacuum causes impurities to accumulate on the filter paper 10 to form a deep filtration layer. Large particles and some micro particles are adsorbed and intercepted through the tiny gaps in the filtration layer, thus initially reducing the solid content of the oil and reducing the load on subsequent treatment.

[0016] The intermediate treatment unit 2 includes a vacuum tank 20, which is an oil-gas separation type. The bottom end of the vacuum tank 20 is fixedly connected to the top end of the vacuum paper tape filter 11 by bolts. The input end of the vacuum tank 20 is fixedly connected to a heater 21 through a pipe, and the output end of the vacuum tank 20 is fixedly connected to a vacuum pump 22 through a pipe. The bottom ends of the heater 21 and the vacuum pump 22 are fixedly connected to the top end of the vacuum paper tape filter 11 by bolts. The oil after primary filtration enters the intermediate treatment unit 2. The oil-gas separation type vacuum tank 20 forms a vacuum environment through the vacuum pump 22 connected by the pipe. In conjunction with the heater 21, the oil is heated, which promotes the evaporation of water and gas in the oil and separates them into the oil-gas separation chamber, thereby achieving deep dehydration and degassing and avoiding oil emulsification and oxidative deterioration.

[0017] The discharge device 4 includes a reducer 40 and an automatic paper winding assembly 41. A slag cart 42 is located below the automatic paper winding assembly 41. The outer wall of the reducer 40 is fixedly connected to the end of the vacuum paper belt filter 11 away from the filter paper 10. The outer wall of the automatic paper winding assembly 41 is fixedly connected to the side wall of the vacuum paper belt filter 11 and is located below the reducer 40. During the entire process, the discharge device 4 operates in coordination. The reducer 40 drives the automatic paper winding assembly 41. After the filter paper 10 is saturated with impurities, it automatically replaces the filter material with new material. Waste filter material and impurities fall into the slag cart 42 below for collection. All devices are fixedly connected by bolts to form a whole. The control system monitors the operating status of each unit in real time and automatically adjusts parameters such as vacuum degree and heating temperature to ensure coordinated linkage of graded filtration and achieve continuous, stable and efficient filtration.

[0018] During use, the oil is initially filtered by the primary filter device 1, then processed by the intermediate treatment device 2, then passed through the multi-stage precision filter 3, and finally discharged from the discharge device 4. The waste oil to be treated first enters the vacuum paper belt filter 11 of the primary filtration device 1. During the rotation of the filter paper 10 on the outer wall, the low flow rate reduces the impurity permeability, while the high vacuum causes the impurities to accumulate on the filter paper 10 to form a deep filtration layer. Large particles and some micro particles are adsorbed and intercepted through the tiny gaps in the filtration layer, thus initially reducing the solid content of the oil and reducing the load on subsequent treatment.

[0019] After primary filtration, the oil enters the intermediate treatment unit 2. The oil-gas separation vacuum tank 20 creates a vacuum environment through a vacuum pump 22 connected by a pipeline. Combined with a heater 21, the oil is heated, causing water and gas in the oil to evaporate and separate into the oil-gas separation chamber. This achieves deep dehydration and degassing, preventing oil emulsification and oxidative deterioration. The intermediate-treated oil then enters the multi-stage precision filter 3 to further remove residual fine impurities, ultimately outputting grinding oil with a cleanliness level of NAS6, meeting the requirements of high-precision grinding.

[0020] Throughout the process, the discharge device 4 operates in coordination, and the reducer 40 drives the automatic paper winding assembly 41. After the filter paper 10 is saturated with impurities, it automatically replaces the filter material with a new one. Waste filter material and impurities fall into the slag cart 42 below for centralized collection. All devices are connected by bolts to form a whole. The control system monitors the operating status of each unit in real time and automatically adjusts parameters such as vacuum degree and heating temperature to ensure coordinated linkage of graded filtration and achieve continuous, stable and efficient filtration.
