Description

Technical Field

[0001] This utility model relates to the field of single-axis vacuum dough mixer technology, specifically a high-temperature oil temperature machine with oil circulation and filtration function. Background Technology

[0002] High-temperature oil temperature controllers are commonly used heating equipment in industrial production. They achieve precise temperature control by heating oil and circulating it to the equipment or workpiece that needs to be heated. However, during long-term circulation, the oil will produce particulate impurities due to mechanical wear. At the same time, the oil will oxidize and deteriorate, generating colloidal contaminants. If these impurities and contaminants accumulate on the surface of oil pipes, heating components, or heat exchange parts, it will lead to a decrease in heat exchange efficiency, an increase in energy consumption, and in severe cases, it will cause pipeline blockage or equipment failure, shortening the service life of the oil temperature controller. However, existing high-temperature oil temperature controllers still have some problems in use: For example, an energy-saving and environmentally friendly high-temperature oil temperature controller with application number CN201920296168.X includes a protective shell, a high-temperature oil temperature controller, a heat dissipation mesh, an isolating and filtering exhaust pipe structure, a buffer protective frame structure, a protective solar charging panel structure, a storage box, a base plate, a support pipe, a support rod, adjusting bolts, a base, a sealing cover, a handle, and a protective sleeve. The high-temperature oil temperature controller is embedded in the upper part of the inner side of the protective shell; the heat dissipation mesh is embedded in the upper part of the inner side of the protective shell; the heat dissipation mesh is located in the upper part of the high-temperature oil temperature controller; the isolating and filtering exhaust pipe structure penetrates the protective shell and is installed in the middle position on the right side of the high-temperature oil temperature controller. Traditional high-temperature oil temperature controllers typically only have a single filter at the oil inlet, resulting in low filtration accuracy. Furthermore, the filter is connected in series with the main circulation loop, requiring the machine to be stopped when the filter element needs to be replaced, which affects production continuity.

[0003] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0004] To address the aforementioned issues, an innovative design was implemented based on the existing high-temperature oil temperature controller. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature oil temperature controller with an oil circulation filtration function, in order to solve the problems mentioned in the background art, where high-temperature oil temperature controllers typically only have a single filter at the oil inlet, resulting in low filtration accuracy. Furthermore, the filter is connected in series with the main circulation loop, requiring machine shutdown for filter element replacement, which affects production continuity.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-temperature oil temperature controller with oil circulation and filtration function includes a housing and an oil tank. The oil tank is placed above a partition at the top of the housing. An exhaust valve and an oil replenishment port extending outwards from the oil tank are located above it. An oil outlet and a return port extending outwards from the front of the housing are located on one side of the oil tank. An oil supply pipeline is sealed to the bottom of the oil tank via a flange. An electric heating element and a circulation pump are installed inside the housing. A branch pipe is connected in parallel to the middle of the oil supply pipeline. A solenoid valve is installed in the middle of the branch pipe. A filter housing is fixed to the bottom of the branch pipe. A primary filter screen is embedded inside the filter housing. A primary filter box and a secondary filter box are located at the bottom of the housing. The bottom of the filter housing is sealed to the primary filter box via a flange. The secondary filter box is connected in parallel to the oil supply pipeline via an oil pipe. Filter components are installed inside both the primary and secondary filter boxes.

[0007] Using the above technical solution, the oil in the storage tank is transported through the oil pipeline, and part of it enters the filter housing, primary filter box and secondary filter box through the branch pipe to complete two-stage filtration. After filtration, the oil merges with the main pipeline oil, is heated by the electric heating tube and driven by the circulation pump, and is supplied to external equipment through the oil outlet. After use, the oil flows back to the storage tank from the return oil port, realizing oil circulation heating and online two-stage filtration to remove impurities and ensure stable equipment operation. In addition, the oil pipeline and the filter components are connected in parallel, which allows the oil to be continuously filtered and circulated without stopping the machine, ensuring the continuity of production. At the same time, the exhaust valve and oil replenishment port facilitate exhaust and timely oil replenishment, meeting the requirements of precise temperature control and oil purification under high temperature conditions.

[0008] Preferably, the filter assembly includes a fixed frame integrally disposed inside the filter box, with positioning screws vertically fixed at the four corners of the fixed frame, a frame attached to the top of the fixed frame, a filter element disposed in the middle of the frame, positioning holes corresponding to the positioning screws being opened at the four corners of the frame, and fastening nuts sleeved on the outer surface of the positioning screws.

[0009] Using the above technical solution, the filter assembly is positioned by the positioning screws of the fixed frame and the positioning holes of the frame, and then locked with fastening nuts, so that the filter element is stably installed in the filter box, providing a fixed carrier for oil filtration, realizing the rapid positioning and firm installation of the filter element, facilitating the subsequent disassembly and replacement of the filter element, while ensuring the stability of the filter element during the filtration process and improving the oil filtration effect.

[0010] Preferably, the pore size of the filter element installed inside the primary filter box is larger than the pore size of the filter element installed inside the secondary filter box, and the pore size of the primary filter screen is larger than the pore size of the filter element installed inside the primary filter box.

[0011] By adopting the above technical solution, the pore size of the filter element installed inside the secondary filter box is smaller than that of the filter element installed inside the primary filter box, and the pore size of the filter element in the filter box is smaller than that of the filter screen inside the filter housing. This allows the oil to pass through coarse filtration, medium filtration, and fine filtration in sequence, intercepting impurities of different sizes at each stage. This prevents large particles from clogging the filter element, extends the service life of the filter element, improves the thoroughness of filtration, and ensures the operation requirements of the high-temperature oil temperature controller.

[0012] Preferably, the oil inlet end of the electric heating tube is sealed to the oil pipeline flange via an oil pipe, and the oil outlet end of the electric heating tube is sealed to the circulating pump flange via an oil pipe, and the oil outlet end of the circulating pump is sealed to one end flange of the oil outlet interface via an oil pipe.

[0013] Using the above technical solution, the oil in the oil pipeline enters the electric heating tube for heating through the oil pipe. The heated oil is then pressurized and transported by the circulating pump and supplied to external equipment through the oil outlet. The oil pipeline is connected to the electric heating tube and the circulating pump by flange sealing, which can ensure sealing and stability when transporting high-temperature oil. With the help of heating by the electric heating tube and pressurization by the circulating pump, the oil temperature is accurately raised and the supply is stable, meeting the high-temperature heat demand of the external equipment.

[0014] Preferably, a control panel is installed on the outer surface of the housing, an alarm is installed on the top of the housing, and the alarm, heating element, circulating pump and solenoid valve are all electrically connected to the control panel.

[0015] By adopting the above technical solution, the control panel is electrically connected to the alarm, electric heating element, circulating pump, and solenoid valve. It centrally receives equipment operation signals and outputs control commands, forming an integrated intelligent control loop. This enables centralized control of core functions such as oil heating, circulation, and filtration. At the same time, the alarm promptly reports equipment abnormalities, improving operational convenience and safety.

[0016] Preferably, the bottom of the outer casing is bolted with casters at the four corners, and the casters have a braking function.

[0017] By adopting the above technical solution, four sets of omnidirectional wheels are installed at the bottom of the machine body, which can be used to move the equipment. The wheels can be locked by the braking function to restrict movement, thereby fixing the position of the equipment and avoiding the impact of accidental movement on the safety and stability of use during operation. This also facilitates the flexible transfer and position adjustment of the high-temperature oil temperature controller.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this high-temperature oil temperature controller with oil circulation and filtration function... 1. The oil in the storage tank is transported through the oil pipeline. Part of it enters the filter housing, primary filter box and secondary filter box through the branch pipe to complete two-stage filtration. After filtration, the oil merges with the main oil, is heated by the electric heating tube and driven by the circulation pump, and is supplied to external equipment through the oil outlet. After use, the oil flows back to the storage tank from the return oil port, realizing oil circulation heating and online two-stage filtration to remove impurities and ensure stable operation of the equipment. In addition, the oil pipeline and the filter components are connected in parallel, which can continuously filter and circulate the oil without stopping the machine, ensuring the continuity of production. 2. The filter assembly is positioned by the positioning screws of the fixed frame and the positioning holes of the frame, and then locked with the fastening nuts, so that the filter element is stably installed in the filter box, providing a fixed carrier for oil filtration, realizing the quick positioning and firm installation of the filter element, facilitating the subsequent disassembly and replacement of the filter element, while ensuring the stability of the filter element during the filtration process and improving the oil filtration effect. 3. By making the pore size of the filter element installed inside the secondary filter box smaller than that of the filter element installed inside the primary filter box, and by making the pore size of the filter element inside the filter box smaller than that of the filter screen inside the filter housing, the oil is filtered through coarse, medium and fine filters in sequence, intercepting impurities of different sizes at each stage. This prevents large particles from clogging the filter element, extends the service life of the filter element, improves the thoroughness of filtration, and ensures the operation requirements of the high-temperature oil temperature controller.

[0021] 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.

[0022] Example 1 Please see Figures 1-5 This utility model provides a technical solution: A high-temperature oil temperature controller with oil circulation and filtration function includes a housing 1 and an oil tank 5. The oil tank 5 is placed above a partition at the top of the housing 1. An exhaust valve 6 and an oil replenishment port 7 extending outwards from the oil tank 5 are located above the housing 1. An oil outlet port 8 and a return port 9 extending outwards from the front of the housing 1 are located on one side of the oil tank 5. An oil supply pipeline 10 is sealed to the bottom flange of the oil tank 5. An electric heating element 11 and a circulation pump 12 are installed inside the housing 1. The oil supply pipeline 10... A branch pipe 13 is connected in parallel to the main body. A solenoid valve 14 is installed in the middle of the branch pipe 13. A filter housing 15 is fixed at the bottom of the branch pipe 13. A primary filter screen 16 is embedded inside the filter housing 15. A primary filter box 17 and a secondary filter box 18 are provided at the bottom of the inner part of the main body 1. The bottom of the filter housing 15 is connected to the primary filter box 17 by a flange seal. The secondary filter box 18 is connected in parallel to the oil supply pipeline 10 by an oil pipe. Both the primary filter box 17 and the secondary filter box 18 are provided with filter components 19. The oil inlet end of the electric heating tube 11 is connected to the oil supply pipeline 10 by a flange seal through an oil pipe. The oil outlet end of the electric heating tube 11 is connected to the circulation pump 12 by a flange seal through an oil pipe. The oil outlet end of the circulation pump 12 is connected to one end of the oil outlet port 8 by a flange seal through an oil pipe.

[0023] This high-temperature oil temperature controller with oil circulation and filtration function outputs oil from the oil storage tank 5 through the oil supply pipeline 10, which is sealed by the bottom flange. A portion of the oil flows along the main pipeline to the inlet of the heating element 11, where it is heated and then transported from the outlet to the circulation pump 12 via an oil pipe. After being pressurized by the circulation pump 12, the oil is sent from the outlet to the outlet port 8 via an oil pipe, providing high-temperature oil for external equipment. The used oil then flows back to the oil storage tank 5 through the return port 9. The other portion of the oil is diverted through a branch pipe 13 connected in parallel in the middle of the oil supply pipeline 10. Under the control of the solenoid valve 14, it enters the filter housing 15, undergoes preliminary coarse filtration through the internally embedded primary filter screen 16, and then flows into the primary filter box 17 through the flange-sealed pipeline. After passing through the internal filter assembly 19... After a single-stage filtration, the oil undergoes further deep filtration through a secondary filter box 18. The filtered clean oil then flows into the main oil pipeline 10 via parallel oil pipes, where it merges with the undiverted oil and participates in heating and transportation. All components are sealed with oil pipe flanges to ensure the sealing and stability of the high-temperature oil transportation. With the design of heating and transportation in the main pipeline and graded filtration in the branch pipelines, the electric heating tube 11 achieves precise oil heating, and the circulating pump 12 ensures a stable supply to meet the high-temperature heat requirements of external equipment. Furthermore, the graded filtration through the primary filter screen 16, the first-stage filter box 17, and the second-stage filter box 18 removes impurities of different sizes from the oil, preventing impurities from affecting equipment operation. At the same time, the exhaust valve 6 can discharge air from the oil circuit, and the oil replenishment interface 7 facilitates oil replenishment, improving the ease of use and operational reliability of the equipment.

[0024] Example 2 Please see Figure 5 This utility model provides a technical solution: The filter assembly 19 includes a fixed frame 1901 integrated inside the filter box. Positioning screws 1902 are vertically fixed at the four corners of the fixed frame 1901. A frame 1903 is attached to the top of the fixed frame 1901. A filter element 1904 is disposed in the center of the frame 1903. Positioning holes 1905 corresponding to the positioning screws 1902 are formed at the four corners of the frame 1903. Fastening nuts 1906 are fitted onto the outer surface of the positioning screws 1902. The aperture of the filter element 1904 installed inside the primary filter box 17 is larger than the aperture of the filter element 1904 installed inside the secondary filter box 18, and the aperture of the primary filter screen 16 is also larger than the aperture of the filter element 1904 installed inside the primary filter box 17.

[0025] This high-temperature oil temperature controller with oil circulation filtration function uses a filter assembly 19, which is mounted on a fixed frame 1901 integrated inside the filter box. The four corner positioning screws 1902 precisely engage with the positioning holes 1905 at the four corners of the frame 1903, and are then locked in place by fastening nuts 1906 on the outer surface of the positioning screws 1902. This securely fixes the stainless steel sintered filter element 1904 in the center of the frame 1903 inside the filter box. Simultaneously, it employs a primary filter screen 16, a primary filter box 17 containing the filter element 1904, and a secondary filter box 18 containing the filter element 1904. The progressively smaller pore size design of filter element 1904 allows the oil to pass through a graded purification process of coarse filtration, medium filtration, and fine filtration. The positioning screw 1902 and fastening nut 1906 enable quick positioning and easy installation and replacement of filter element 1904. The graded filtration design also prevents large particles of impurities from directly clogging the high-precision filter element 1904 in the secondary filter box 18, extending the service life of filter element 1904. At the same time, it gradually intercepts impurities of different sizes in the oil, significantly improving the cleanliness of the oil and providing clean oil to ensure the stable operation of the high-temperature oil temperature controller.

[0026] Example 3 Please see Figure 1 , Figure 2 This utility model provides a technical solution: A control panel 2 is mounted on the outer surface of the casing 1. An alarm 4 is mounted on the top of the casing 1, and the alarm 4, heating element 11, circulation pump 12, and solenoid valve 14 are all electrically connected to the control panel 2. Universal wheels 3 are bolted to the four corners of the bottom of the casing 1, and the universal wheels 3 have a braking function.

[0027] This high-temperature oil temperature controller with oil circulation and filtration function establishes an electrical connection between the control panel 2 on the outer surface of the casing 1 and the alarm 4, electric heating element 11, circulation pump 12, and solenoid valve 14, forming a centralized control loop. Operators can set parameters and output control commands through the control panel 2 to achieve integrated control of oil heating, circulation, and filtration branch on / off. At the same time, when the equipment malfunctions such as abnormal oil temperature or excessive pressure, the control panel 2 will trigger the alarm 4 to issue a warning signal. The universal wheels 3 at the four corners of the bottom of the casing 1 are fixed with bolts, which realize flexible transportation and position adjustment of the equipment by means of rolling characteristics. The built-in braking function can lock the wheels after the equipment is in place to avoid affecting the oil circuit sealing stability or causing safety hazards due to accidental movement during operation. This not only improves the convenience and safety of equipment operation, but also enhances the site adaptability of the equipment and meets the needs of movement and fixation under different working conditions.

[0028] Working principle: After the equipment is started, the operator sets parameters and issues a start command through the control panel 2 on the outer surface of the machine casing 1. The solenoid valve 14, the heating element 11, and the circulation pump 12, which are electrically connected to the control panel 2, start synchronously. The oil in the oil storage tank 5 is output through the oil supply pipeline 10, which is sealed by the bottom flange. A portion of the oil flows along the main pipeline to the oil inlet of the heating element 11. After being heated by the heating element 11, it is transported to the circulation pump 12 through the oil outlet through the oil pipe. After being pressurized by the circulation pump 12, it is sent to the oil outlet port 8 through the oil pipe from the oil outlet to provide high-temperature oil for external equipment. The used oil then flows back to the oil storage tank 5 through the return oil port 9. The other portion of the oil is diverted through the branch pipe 13 connected in parallel in the middle of the oil supply pipeline 10 and enters the filter housing 1 under the control of the solenoid valve 14. 5. After initial coarse filtration by the internally embedded primary filter 16, the oil flows into the first-stage filter box 17 through the flange-sealed pipeline. It is further filtered by the internal filter assembly 19, and then deeply filtered by the second-stage filter box 18. The filtered clean oil flows into the main line of the oil supply pipeline 10 through the parallel oil pipe, and then merges with the undiverted oil to participate in the heating and transportation. During operation, if the equipment experiences abnormal oil temperature or excessive pressure, the control panel 2 will trigger the alarm 4 on the top of the machine casing 1 to issue a warning signal. The universal casters 3 with brake function connected by four corner bolts at the bottom of the machine casing 1 can lock the wheels after the equipment is in place to ensure stable operation. At the same time, the exhaust valve 6 on the top of the oil tank 5 can discharge air from the oil circuit, and the oil replenishment interface 7 facilitates timely replenishment of oil, ensuring that the entire process continues to operate efficiently.

[0029] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
