Description

Technical Field

[0001] This utility model relates to the field of paraffin filtration, specifically to a paraffin heating and filtration device. Background Technology

[0002] Paraffin wax is extracted from certain distillates of petroleum, shale oil, or other bituminous mineral oils. It is a white or pale yellow translucent substance. Paraffin wax is classified into three categories based on its degree of refining: fully refined, semi-refined, and crude. It has a wide range of uses, including food packaging, waxed paper, crayons, and pharmaceutical sealing. It can also be used in high-frequency ceramics, electronic component insulation, precision casting, and waterproof coatings. Furthermore, it serves as a fruit preservative, rubber softener, and a lubricant or embedding agent in laboratories. Today, paraffin wax is present in every aspect of human production activities and is inseparable from human life.

[0003] The initial state of the processed paraffin wax is liquid paraffin wax, which contains various impurities, including solid impurities and other high-melting-point liquid impurities. To ensure the purity of the paraffin wax product, it needs to be filtered. Existing paraffin wax filtration processes typically require heating to a waxy liquid state before a filtration device removes solid particulate impurities. However, in practical use, traditional filtration devices can only add a certain amount of paraffin wax at a time for batch heating and filtration, failing to achieve continuous addition and discharge, resulting in low filtration efficiency. Therefore, we propose a paraffin wax heating and filtration device that enables automatic continuous filtration. Summary of the Invention

[0004] To address the aforementioned shortcomings of the existing technology, this utility model provides a paraffin heating and filtering device.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows: it includes a heated filter tank, a filter cover disposed inside the heated filter tank, and an overflow filter pipe disposed at the bottom of the heated filter tank. The filter cover has a filter opening on its side and covers the outside of the overflow filter pipe. A filter screen is disposed on the top of the overflow filter pipe. A feeding pipe is disposed on the top of the heated filter tank, and a tank heating component is disposed outside the feeding pipe. A liftable lifting shaft is disposed on the top of the heated filter tank. The bottom of the lifting shaft is fixedly connected to the filter cover, and the top of the lifting shaft is connected to the heated filter tank through a telescopic cylinder.

[0006] Furthermore, it also includes an outer rotating cylinder disposed outside the lifting shaft, on which a material leveling assembly is fixed. The material leveling assembly includes an inner sleeve fixed on the outer rotating cylinder, a plurality of material leveling blades fixed outside the inner sleeve, and an outer connecting ring fixed to the plurality of material leveling blades.

[0007] Furthermore, a drive assembly is provided on the top of the outer rotating cylinder. The drive assembly includes a motor, a drive gear fixed to the output end of the motor, and a driven gear mounted on the top of the outer rotating cylinder. The drive gear meshes with the driven gear.

[0008] Furthermore, a flange is provided on the heating filter tank, and a sealing flange plate is provided on the flange.

[0009] Furthermore, a temperature sensor is installed inside the heated filter tank, and the temperature sensor is electrically connected to the PLC controller.

[0010] Furthermore, when the filter cover is in its lowest position, the top height of the overflow filter tube is higher than the top height of the filter opening.

[0011] Furthermore, the tank heating assembly is a flexible heating jacket.

[0012] Furthermore, the telescopic cylinder is either an electric telescopic rod or a hydraulic cylinder.

[0013] The beneficial effects of this utility model are as follows:

[0014] The paraffin heating and filtering device of this utility model forms a communicating vessel structure through a filter cover, a filter opening and an overflow filter pipe. Through the principle of communicating vessels, after solid paraffin is added, the melted paraffin can be automatically filtered and discharged, thereby realizing continuous filtration of paraffin.

[0015] The driving component of this invention drives the outer rotating cylinder and the uniform material component to rotate. The rotating uniform material component can guide and disperse the falling solid paraffin wax, thereby dispersing the solid paraffin wax to various parts inside the heating and filtering tank. The solid paraffin wax accumulates inside the heating and filtering tank, allowing it to melt efficiently.

[0016] The telescopic cylinder of this invention can drive the filter cover to rise and fall via a lifting shaft. When the filter cover is at its lowest position, the bottom of the filter cover contacts the bottom of the heated filter tank. At this time, the filter cover covers the outside of the overflow filter pipe, and the filter cover and the overflow filter pipe form a communicating vessel. When the filter cover is at its highest position, the bottom of the filter cover protrudes from the top of the overflow filter pipe, facilitating the replacement or cleaning of the filter cover at the top of the overflow filter pipe.

Detailed Implementation

[0021] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0022] like Figure 1 As shown, the paraffin heating and filtering device includes a heating and filtering tank 1, a filter cover 3 disposed inside the heating and filtering tank 1, and an overflow filter pipe 2 disposed at the bottom of the heating and filtering tank 1. The filter cover 3 has filter openings on its sides and covers the overflow filter pipe 2. A filter screen 4, which is barrel-shaped, is disposed on the top of the overflow filter pipe 2 and is inserted and fixed to the top of the overflow filter pipe 2. A feeding pipe 11 is disposed on the top of the heating and filtering tank 1, and a tank heating assembly 12 is disposed outside the feeding pipe 11. The tank heating assembly 12 is preferably a flexible heating sleeve. A liftable lifting shaft 5 is disposed on the top of the heating and filtering tank 1. The bottom of the lifting shaft 5 is fixedly connected to the filter cover 3, and the top of the lifting shaft 5 is connected to the heating and filtering tank 1 through a telescopic cylinder 6. The telescopic cylinder 6 is preferably an electric telescopic rod or a hydraulic cylinder. When the filter cover 3 is in its lowest position, the top of the overflow filter pipe 2 is higher than the top of the filter opening. The overflow filter pipe 2, in conjunction with the filter opening, allows the melted paraffin wax at the bottom to be filtered and discharged, achieving the filtration of melted paraffin wax. Simultaneously, it prevents unmelted paraffin wax from entering and being filtered out through the overflow filter pipe 2, thus achieving continuous paraffin wax filtration. A tank heating assembly 12 is also installed outside the overflow filter pipe 2. The tank heating assembly 12 heats the overflow filter pipe 2, allowing the filtered melted paraffin wax to be discharged smoothly.

[0023] like Figure 2 As shown, it also includes an outer rotating cylinder 7 disposed outside the lifting shaft 5. A material leveling assembly 8 is fixed on the outer rotating cylinder 7. The material leveling assembly 8 includes an inner sleeve 81 fixed on the outer rotating cylinder 7, a plurality of material leveling blades 82 fixed outside the inner sleeve 81, and an outer connecting ring 83 fixed to the plurality of material leveling blades 82. The material leveling assembly 8 can also be a conical frustum mask with a frosted upper surface, which can also guide and disperse the falling solid paraffin wax.

[0024] A drive assembly 9 is installed at the top of the outer rotating cylinder 7. The drive assembly 9 drives the outer rotating cylinder 7 and the material leveling assembly 8 to rotate. The rotating material leveling blades 8 can guide and disperse the solid paraffin falling from the feeding pipe 11, preventing the solid paraffin from accumulating inside the heating filter tank 1, so that the solid paraffin can be uniformly heated and melted in the heating filter tank 1. The drive assembly 9 includes a motor 93, a drive gear 92 fixed to the output end of the motor 93, and a driven gear 91 fixed to the top of the outer rotating cylinder 7. The drive gear 92 meshes with the driven gear 91. The length of the outer rotating cylinder 7 is half the length of the lifting shaft 5. When the filter cover 3 is raised and lowered to its highest position, the bottom of the filter cover 3 can expose the top of the overflow filter pipe 2, thereby facilitating the subsequent cleaning or replacement of the filter screen 4. Specifically, the motor 93 drives the driven gear 91 to rotate through the drive gear 92, and the driven gear 91 drives the outer rotating cylinder 7 to rotate, thereby using the rotating material leveling assembly 8 to guide and disperse the falling solid paraffin.

[0025] In this embodiment, a flange is provided on the heating filter tank 1, and a sealing flange plate 13 is provided on the flange. By disassembling the sealing flange plate 13, the heating filter tank 1 can be cleaned and the filter screen 4 can be replaced conveniently.

[0026] In this embodiment, a temperature sensor is installed inside the heated filter tank 1, and the temperature sensor is electrically connected to the PLC controller. The temperature sensor enables real-time monitoring of the temperature inside the heated filter tank 1, allowing the PLC controller to control the tank heating assembly 12 to maintain the temperature of the heated filter tank 1 within a suitable range, thereby melting the paraffin wax. The PLC controller is electrically connected to the telescopic cylinder 6 and the motor 93, facilitating the control of the rotation of the material leveling assembly 8 and the lifting and lowering of the filter cover 3. A control panel is also included, comprising a power switch, a lifting switch, a stirring switch, and a digital display panel for showing the temperature.

[0027] Working process and principle: S1. First, start the tank heating component 12 to heat the temperature inside the heating filter tank 1 to the preset value, and raise and lower the filter cover 3 to a position that is in contact with the bottom of the heating filter tank 1; S2. Heat solid paraffin wax into the heating filter tank 1 through the feeding pipe 11, so that the volume of solid paraffin wax is at the top position of the filter cover 3; S3. The solid paraffin wax gradually melts in the heating filter tank 1. After the added paraffin wax melts, add an equal amount of solid paraffin wax continuously through the feeding pipe 11, and guide and disperse the solid paraffin wax through the rotating uniform blades; S4. The solid paraffin wax that is guided and dispersed falls onto the surface of the melted paraffin wax. The solid paraffin wax will float on the surface of the melted paraffin wax. Due to the connecting effect of the filter opening on the filter cover 3 and the overflow filter pipe 2, every time a certain amount of solid paraffin wax is added, an equal amount of melted paraffin wax can be filtered and discharged from the overflow filter pipe 2, thereby realizing the continuous filtration operation of paraffin wax.
