[0002] Torreya oil is a high-quality edible oil extracted from the seeds of Torreya grandis. It not only has a unique taste, but also has high nutritional value. It is rich in monounsaturated and polyunsaturated fatty acids, which helps maintain cardiovascular health. In addition, Torreya grandis oil is rich in vitamin E and has good antioxidant properties. It can effectively resist free radicals, delay aging, and enhance immunity. Due to its healthy properties, Torreya grandis oil has gradually become one of the preferred choices in people's daily diet.

[0003] The prior art provides a rapeseed oil pressing and continuous filtration production system. By setting two filter boxes, when one filter box works for a long time and causes the filter screen in the filter box to be blocked, it can be switched to the other filter box for continuous filtration and purification, thereby improving production efficiency and ensuring the quality of rapeseed oil.

[0004] However, the above method is not convenient for cleaning the blocked filter in the filter box, and using two filter boxes at the same time will take up more space and increase the placement cost. Summary of the invention

[0011] Wherein, the sliding filter structure includes a control cylinder, a push frame and a third filter plate, the push frame is slidably arranged in the filter box, the third filter plate is arranged on the push frame, and the output end of the control cylinder is connected to the third filter plate.

[0012] Wherein, the sliding filtering structure further comprises a sealing frame, and the sealing frame is arranged between the pushing frame and the filtering box.

[0013] Among them, the Torreya grandis oil separation and purification mechanism also includes a control structure, which includes a photoelectric detection unit, a judgment unit and a control unit. The photoelectric detection unit is used to be installed on the push frame to detect the photoelectric signal returned by the first filter plate. The judgment unit is used to judge whether the change of the photoelectric signal continues for an expected time period. The control unit is used to control the movement of the control cylinder after the photoelectric signal continues for an expected time period.

[0014] In a second aspect, the present invention further provides a method for separating and purifying Torreya grandis oil, comprising: injecting the squeezed oil into the filter box, and starting a pressure pump to drive the oil to flow;

In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0031] First embodiment

[0032] See also Figure 1 to Figure 6The present invention provides a mechanism for separating and purifying Chinese torreya oil, comprising a filter box 101, a pressure pump 102, a first filter plate 103, a second filter plate 104, a closed structure 105 and a sliding filter structure 106. The filter box 101 has a feed pipe 107 and a discharge pipe 108. The first filter plate 103 is slidably arranged in the filter box 101, and the second filter plate 104 is arranged in the discharge pipe 108. The closed structure 105 is arranged on one side of the first filter plate 103 to reduce oil leakage when the first filter plate 103 is replaced. The sliding filter structure 106 is slidably arranged on one side of the first filter plate 103. The pressure pump 102 is used to provide negative pressure at the discharge pipe 108.

[0033] In this embodiment, the filter box 101 is the core part of the whole device, and is responsible for receiving the raw materials and filtering them. It is equipped with a feed pipe 107 and a discharge pipe 108, which are used for the input of raw materials and the output of finished oil respectively. The pressure pump 102 is installed near the discharge pipe 108, and helps to facilitate the smooth discharge of oil from the filter box 101 by providing the necessary negative pressure environment, and also helps to improve the filtering efficiency.

[0034] The first filter plate 103 is located inside the filter box 101 and adopts a slidable design, so that the user can replace the filter plate as needed to adapt to raw material particles of different coarseness. This design not only improves the flexibility of the equipment, but also facilitates maintenance and cleaning. The second filter plate 104 is arranged inside the discharge pipe 108 to play a secondary filtering role to ensure the quality of the final product. Compared with the first filter plate 103, it may have a finer mesh to further remove residual impurities. The closed structure 105 is adjacent to one side of the first filter plate 103. When the first filter plate 103 needs to be replaced, this structure can effectively reduce the leakage of oil, keep the operating environment clean, and reduce the waste of raw materials.

[0035] The sliding filter structure 106 is also installed beside the first filter plate 103. This component can move along a specific track according to actual needs, and assists in fine filtering of the oil when replacing the first filter plate 103. Its existence increases the functionality and adaptability of the device, and can better meet the specific requirements of different batches of raw materials.

[0036] In summary, the above structure can more conveniently replace the filter plate, and can continue filtering by sliding the filter structure 106 during replacement, so that continuous operation can be achieved, thereby improving work efficiency.

[0037] The first filter plate 103 has a handle 109 , and the handle 109 is disposed on one side of the first filter plate 103 .

[0038] A handle 109 is provided on one side of the first filter plate 103. This design not only facilitates the operator to manually move or replace the filter plate, but also improves the safety and convenience of operation. The shape and size of the handle 109 are ergonomically optimized to ensure a comfortable feel during use, and no fatigue will be felt even after long-term operation.

[0039] The closed structure 105 includes two pressure plates 110, two supporting springs 111, a reflow channel 112 and a one-way valve 113. The two pressure plates 110 are rotatably arranged on both sides of the first filter plate 103. The two supporting springs 111 are used to support the two pressure plates 110. The reflow channel 112 is arranged at the bottom of the pressure plate 110, and the one-way valve 113 is arranged in the reflow channel 112.

[0040] The closed structure 105 includes two pressing plates 110, which are respectively installed on both sides of the first filter plate 103 and can be rotated to adjust the angle. When the filter plate needs to be replaced, the two pressing plates 110 can be tightly attached to the inner wall of the filter box 101 to form a temporary sealing area, effectively preventing oil leakage during this process.

[0041] Two supporting springs 111 are installed under each pressing plate 110. The main function of these springs is to apply a certain pressure to the pressing plate 110 to ensure close contact between it and the inner wall of the filter box 101. The elastic force of the spring can be adjusted according to actual conditions to adapt to different working conditions. A return channel 112 is provided at the bottom of each pressing plate 110 to collect a small amount of oil that may leak out due to the replacement of the filter plate. The existence of the return channel 112 reduces the waste of oil and helps to maintain a clean working environment. The one-way valve 113 located inside the return channel 112 is a key component. Its function is to allow oil to flow from the working area to the return channel 112, but prevent the oil from flowing in the opposite direction. In this way, even in the process of replacing the filter plate, it can be ensured that the oil will not flow back to the working area, thereby avoiding contamination of the new filter plate or affecting subsequent operations.

[0042] Overall, this series of designs not only take into account practicality, but also fully reflect the importance of environmental protection and resource conservation. Through these sophisticated designs, the Torreya oil separation and purification mechanism can not only ensure high efficiency, but also greatly improve the safety of operation and environmental protection performance.

[0043] The pressurizing structure further includes a sealing strip 114 , which is fixedly connected to the pressing plate 110 and is located between the pressing plate 110 and the filter box 101 .

[0044] The sealing strip 114 is fixedly connected to the edge of the pressing plate 110 and is located between the pressing plate 110 and the inner wall of the filter box 101. This design ensures that when the pressing plate 110 is close to the inner wall of the filter box 101, the sealing strip 114 can form an effective barrier to prevent oil from leaking from the gap between the pressing plate 110 and the filter box 101. The sealing strip 114 is usually made of oil-resistant, wear-resistant, and high-temperature resistant materials, such as silicone rubber or Teflon. These materials not only have good sealing performance, but can also withstand long-term high temperature and high pressure environments, ensuring reliability and durability for long-term use.

[0045] The pressurizing structure further includes a second pump. The pressurizing pump 102 is disposed on one side of the return channel 112 .

[0046] The second pump is arranged at one side of the return channel 112 and connected to the return channel 112. This arrangement enables the second pump to directly apply a certain pressure to the oil in the return channel 112, ensuring that the oil can smoothly flow back into the filter box 101.

[0047] The sliding filter structure 106 includes a control cylinder 116, a push frame 117 and a third filter plate 118. The push frame 117 is slidably arranged in the filter box 101. The third filter plate 118 is arranged on the push frame 117. The output end of the control cylinder 116 is connected to the third filter plate 118.

[0048] The control cylinder 116 is installed outside the filter box 101, and its output end is connected to the third filter plate 118 through a mechanical connector. This design enables the control cylinder 116 to accurately control the movement of the third filter plate 118. The main function of the control cylinder 116 is to provide power to slide the third filter plate 118 along a predetermined track in the filter box 101. By adjusting the telescopic action of the cylinder, the third filter plate 118 can be moved forward and backward, thereby completing the fine filtering and cleaning of the oil.

[0049] The push frame 117 is slidably disposed inside the filter box 101, between the first filter plate 103 and the second filter plate 104. The structural design of the push frame 117 enables it to slide smoothly inside the filter box 101, ensuring the stability and reliability of the filtering process.

[0050] The third filter plate 118 is fixedly mounted on the push frame 117 and connected to the push frame 117 through the output end of the control cylinder 116. This design enables the third filter plate 118 to slide with the push frame 117 to achieve the dual functions of filtering and cleaning. The third filter plate 118 is mainly used for further fine filtering of the oil. Its mesh is finer than the first filter plate 103 and the second filter plate 104, and it can remove smaller impurities to ensure the purity of the final product.

[0051] The sliding filtering structure 106 further includes a sweeping brush 119 , and the sweeping brush 119 is disposed on one side of the pushing frame 117 .

[0052] The sweeping brush 119 is arranged on one side of the pushing frame 117 and is usually made of soft bristles or nylon threads. The length and density of the sweeping brush 119 are optimized to ensure that the sweeping brush 119 can effectively clean the residues on the second filter plate 104.

[0053] The sliding filtering structure 106 further includes a sealing frame 120 , which is disposed between the pushing frame 117 and the filtering box 101 .

[0054] The sealing frame 120 is disposed between the push frame 117 and the filter box 101, and is usually made of an elastic material, such as rubber or silicone. The shape and size of the sealing frame 120 are precisely designed to ensure that it can fit tightly between the push frame 117 and the filter box 101. The main function of the sealing frame 120 is to prevent the oil from leaking from the gap during the sliding process of the push frame 117, and to maintain the sealing inside the filter box 101. This not only reduces the waste of oil, but also keeps the working environment clean.

[0055] The Torreya grandis oil separation and purification mechanism also includes a control structure, which includes a photoelectric detection unit 122, a judgment unit 123 and a control unit 124. The photoelectric detection unit 122 is used to be installed on the push frame 117 to detect the photoelectric signal returned by the first filter plate 103. The judgment unit 123 is used to judge whether the change of the photoelectric signal continues for an expected time period. The control unit 124 is used to control the movement of the control cylinder 116 after the photoelectric signal continues for an expected time period.

[0056] The photoelectric detection unit 122 is mounted on the push frame 117 and is located near the third filter plate 118. The photoelectric detection unit 122 is usually composed of a light source (such as an LED) and a photosensitive element (such as a photodiode) for emitting and receiving light. The main function of the photoelectric detection unit 122 is to detect the photoelectric signal on the first filter plate 103. When the push frame 117 slides in the filter box 101, the photoelectric detection unit 122 will continuously monitor the state of the first filter plate 103 and determine the position and state of the filter plate by detecting the change of the photoelectric signal.

[0057] The judgment unit 123 is usually located in the central processing unit of the control system, connected to the photoelectric detection unit 122 through a data line, and receives the electrical signal from the photoelectric detection unit 122. The main function of the judgment unit 123 is to analyze the photoelectric signals transmitted by the photoelectric detection unit 122 and determine whether the changes in these signals continue for a certain expected time period. This expected time period can be set according to actual needs to ensure the accuracy of the judgment.

[0058] The control unit 124 is usually located on the main control board of the control system, connected to the judgment unit 123 and the control cylinder 116 through a data line, and receives control instructions from the judgment unit 123. The main function of the control unit 124 is to control the movement of the control cylinder 116 after the judgment unit 123 confirms that the photoelectric signal change continues for an expected period of time. By controlling the telescopic action of the cylinder 116, the push frame 117 can drive the third filter plate 118 to slide in the filter box 101, so that the auxiliary filtering operation can be performed after the first filter plate 103 is pulled out.

[0059] The Torreya grandis oil separation and purification mechanism also includes a cleaning structure 125, which includes a lifting plate 126, a control rope 127, a winding mechanism 128, a cleaning bin 129, a control plate 130 and a cover plate 131. The lifting plate 126 has a through hole, and the lifting plate 126 is slidably arranged in the filter box 101. The cleaning bin 129 is arranged on the top of the lifting plate 126. The control rope 127 is connected to the lifting plate 126. The winding mechanism 128 is connected to the control rope 127 and is located on one side of the cleaning bin 129. The control plate 130 and the cover plate 131 are slidably arranged on both sides of the cleaning bin 129.

[0060] The lifting plate 126 is slidably arranged in the filter box 101, and is located at the bottom or the middle of the filter box 101. The lifting plate 126 is provided with through holes, which are used to allow oil to pass through. At the same time, when the lifting plate 126 rises, it can bring up the impurities deposited at the bottom of the filter box 101. The main function of the lifting plate 126 is to bring the impurities and residues at the bottom of the filter box 101 to the top for easy cleaning. Through the sliding arrangement, the lifting plate 126 can move up and down in the filter box 101, so as to achieve efficient cleaning of the bottom sediment.

[0061] One end of the control rope 127 is connected to the lifting plate 126, and the other end is connected to the winding mechanism 128. The control rope 127 is usually made of high-strength fiber materials, such as nylon or steel wire rope, to ensure that it is not easy to break during repeated stretching and contraction. The main function of the control rope 127 is to transmit power. Through the control of the winding mechanism 128, the lifting plate 126 can be moved up and down in the filter box 101. When the winding mechanism 128 winds up the control rope 127, the lifting plate 126 will rise; when the winding mechanism 128 releases the control rope 127, the lifting plate 126 will fall.

[0062] The winding mechanism 128 is arranged at one side of the cleaning chamber 129, and is generally composed of a motor, a reducer and a reel. The motor drives the reel to rotate through the reducer, thereby realizing the retraction and release of the control rope 127. The main function of the winding mechanism 128 is to drive the lifting plate 126 to move up and down in the filter box 101 by retracting and releasing the control rope 127. The speed and direction of the motor can be adjusted by the control system to realize the precise control of the movement of the lifting plate 126.

[0063] The cleaning bin 129 is disposed on the top of the lifting plate 126, above the filter box 101. The cleaning bin 129 is generally a closed container, and is provided with cleaning tools and a collecting device inside, for collecting and processing impurities and residues brought up from the lifting plate 126. The main function of the cleaning bin 129 is to provide a closed environment, so that the impurities and residues brought up by the lifting plate 126 can be centrally cleaned and processed therein. The design of the cleaning bin 129 can effectively prevent impurities and residues from falling into the filter box 101 again, and keep the filter box 101 clean.

[0064] The control panel 130 is slidably disposed on one side of the cleaning bin 129 and is usually made of a light material, such as aluminum alloy or plastic. A handle or button is provided on the control panel 130 to facilitate the operator to manually control its sliding. The main function of the control panel 130 is to control the opening and closing of the cleaning bin 129. When opened, the lifting plate 126 can enter the cleaning bin 129.

[0065] The main function of the cover plate 131 is to cooperate with the control panel 130 to jointly control the opening and closing of the cleaning chamber 129. When cleaning is required, the operator can slide the cover plate 131 to open the entrance of the cleaning chamber 129 to process the internal impurities.

[0066] Second embodiment

[0067] See also Figure 7 The present invention also provides a method for separating and purifying Torreya grandis oil, comprising:

[0068] S201 injects the squeezed oil into the filter box 101 and starts the pressure pump 102 to drive the oil to flow;

[0069] First, the squeezed Torreya grandis oil is injected into the filter box 101 through the feed pipe 107. During the oil injection process, the oil should be evenly distributed to avoid partial overfilling or underfilling. After the oil injection is completed, the pressure pump 102 is started to provide negative pressure at the discharge pipe 108 to promote the oil to flow in the filter box 101.

[0070] The negative pressure of the pressure pump 102 ensures that the oil can pass through the filter box 101 evenly, creating good conditions for the subsequent filtering process.

[0071] S202 The first filter plate 103 performs a primary filtration on the grease, and the second filter plate 104 performs a secondary filtration on the grease;

[0072] After the oil enters the filter box 101, it is first filtered by the first filter plate 103. The mesh of the first filter plate 103 is relatively large, and it is mainly used to remove larger impurities and particles. The oil that passes through the first filter plate 103 then flows into the discharge pipe 108, and in this process, it is filtered twice by the second filter plate 104. The mesh of the second filter plate 104 is relatively fine, which can further remove fine impurities and ensure the purity of the oil.

[0073] Through two filtrations, impurities in the oil are gradually removed, improving the quality and purity of the final product.

[0074] S203, after the first filter plate 103 has been used for an expected time, the sliding filter structure 106 is started to approach the first filter plate 103;

[0075] When the first filter plate 103 is used for an expected time (usually determined according to actual usage and filtering effect), the sliding filter structure 106 is started. The control cylinder 116 in the sliding filter structure 106 pushes the frame 117 and the third filter plate 118 to move closer to the first filter plate 103.

[0076] By sliding the filter structure 106 closer, preparation is made for replacing the first filter plate 103, while ensuring the continuity of the filtering process.

[0077] S204: Slide the first filter plate 103 upwards, and the sealing structure 105 is close to the first filter plate 103 to reduce leakage. At this time, the sliding filter structure 106 is used to reset, and then the first filter plate 103 is replaced;

[0078] Start the control cylinder 116 to make the first filter plate 103 slide upward along the slide rail out of the filter box 101. During the sliding out process of the first filter plate 103, the pressure plate 110 in the closed structure 105 will be pressed against the inner wall of the filter box 101 under the action of the support spring 111, forming a temporary sealing area to reduce the leakage of oil. The third filter plate 118 in the sliding filter structure 106 continues to slide and returns to the initial position to ensure the continuity of the filtering process. The operator can safely replace the first filter plate 103 to ensure the filtering effect.

[0079] S205 The sliding filter structure 106 is reset. During the reset process, the grease reversely flushes the sliding filter structure 106 and is filtered through the second filter plate 104 .

[0080] The third filter plate 118 in the sliding filter structure 106 slides back to the initial position along the predetermined track under the drive of the control cylinder 116. During the resetting process of the sliding filter structure 106, the oil will reversely flush the sliding filter structure 106, especially the third filter plate 118, to remove the residue on its surface.

[0081] The oil after backwashing is filtered again through the second filter plate 104 to ensure the purity of the oil.

[0082] By backwashing, the residue on the sliding filter structure 106 is removed to ensure the continuous stability of the filtering effect.

[0083] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
