Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil press technology, and more specifically to a heating device and an oil press having the same. Background Technology
[0002] An oil press is a machine that uses external mechanical force to increase temperature, activate oil molecules, and squeeze oil out of oilseeds.
[0003] Oil presses typically have heating devices installed in the pressing chamber to improve the oil yield of the raw materials (peanuts, soybeans, etc.). For example, Chinese Patent (Publication No.: CN208452403U) discloses a two-sided detachable heating device for an oil press, including a pressing chamber with an aluminum sleeve on the outside. The aluminum sleeve is interference-fitted to the pressing chamber. A first heating block is located on one side of the outer edge of the aluminum sleeve, and a second heating block is located on the other side. This heating device features large-area heating, ensuring uniform heating of the pressing chamber. Furthermore, the heating device can be easily separated from the pressing chamber for cleaning, effectively eliminating electrical safety hazards and food safety risks associated with oil presses. Another example is Chinese Patent (Publication No.: CN215970243U), which discloses an oil press including a body, pressing components, and a cover. The cover has a heating element in the shape of a semi-circular, half-tubular tube.
[0004] However, current oil presses primarily rely on a 180°C or 300°C heating block for heating the pressing chamber, while heat transfer is achieved through the interference fit between the aluminum sleeve and the pressing chamber. While this technology is acceptable for low-efficiency or short-duration pressing scenarios, it has significant limitations. Because the bottom of the heat-conducting aluminum sleeve lacks direct heating, heat dissipates rapidly. This leads to increased heat loss during prolonged operation or when pursuing higher efficiency, directly impacting oil quality and yield. Furthermore, the interference fit assembly process between the heat-conducting aluminum sleeve and the pressing chamber is complex, requiring a hydraulic press. This not only makes operation cumbersome but also limits the ease of replacement of the heat-conducting aluminum sleeve, increasing maintenance difficulty and cost.
[0005] Therefore, how to provide a heating device that can achieve 360-degree annular heating of the pressing chamber, ensure minimal heat loss during continuous and efficient operation of the oil press, and improve oil quality and yield is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0006] In view of this, the present invention provides a heating device and an oil press having the same, which, compared with the prior art, saves the installation process of the heat-conducting aluminum sleeve, simplifies the production process, and improves the overall flexibility and ease of use of the heating device.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A heating device includes a heating body, a heat-conducting core, and a heating element;
[0009] The bottom wall of the heating body is provided with a sliding groove that extends through both end faces of the heating body, and the top wall is provided with an assembly groove; the heat-conducting core is slidably connected in the sliding groove, and there is a heating cavity between the top wall of the heat-conducting core and the inner wall of the bottom of the sliding groove.
[0010] The heating element is inserted into the assembly slot to provide heat to the heating cavity through the heating body.
[0011] The beneficial effects of this utility model are that the heating cavity formed by the heat-conducting core and the heating body can surround the equipment to be heated, and heat is provided to the heating cavity through the heating element, which can provide 360° annular heating to the equipment to be heated. The detachable connection between the heat-conducting core and the heating body facilitates the installation, removal and maintenance of the heating device. The heating element can be replaced by pulling it out of the assembly slot, which improves the overall flexibility and ease of use of the heating device.
[0012] Preferably, the device further includes a limiting plate, one end of which is hinged to a side wall of the heating body, and the other end of which abuts against a side end face of the heat-conducting core to restrict its axial sliding relative to the slide groove. The limiting plate can restrict the sliding of the heat-conducting core along the slide groove, preventing the heat-conducting core from slipping during use and affecting the heating effect.
[0013] Preferably, it also includes a cover plate, with the top surface of the heating body open relative to the top surface of the mounting slot, and the cover plate being bolted to the top surface of the heating body to cover the heating element. The mounting slot can be directly opened on the top surface of the heating body, covered by the cover plate, and the heating element can be replaced by removing the cover plate.
[0014] Preferably, a locking block is fixed to the bottom of the inner sidewall of the sliding groove of the heating body, and the top surface of the locking block slides against the bottom surface of the heat-conducting core. The locking block can lock the heat-conducting core onto the heating body, ensuring an effective connection between the heating body and the heat-conducting core during the test.
[0015] Preferably, the top surface of the heat-conducting core has a first fastening cavity, and the inner wall of the bottom of the groove has a second fastening cavity. The first fastening cavity and the second fastening cavity fasten together to form the heating cavity. The heating cavity is formed by the fastening of the first and second fastening cavities. The heating element provides heat to the heating body, and together with the heat-conducting core, it can provide all-round heat support to the heating cavity.
[0016] Preferably, the heating cavity is circular, square, or trapezoidal, to meet the usage requirements of heating devices of different shapes.
[0017] This utility model also provides an oil press, which adopts the heating device in the above technical solution. The oil press includes a shell, a flip cover and a pressing chamber. The flip cover is hinged to an outer side wall of the shell. The pressing chamber is located below the flip cover, with one end fixed to the outer side wall of the shell and the other end penetrating through the heating cavity.
[0018] The beneficial effects of this utility model are that the pressing chamber of the oil press is connected to the heating cavity, and the pressing chamber can be heated in a 360-degree ring through the heating plate and the heat-conducting core. This ensures that the heat loss of the oil press is extremely low during continuous and efficient operation, and the heat transfer efficiency is significantly improved, thereby improving the quality of oil pressing and the oil yield. At the same time, it also saves the installation process of the heat-conducting aluminum sleeve and simplifies the production process.
[0019] Preferably, the device also includes multiple screws, with the ends of the screws vertically penetrating the top wall of the heating body and fastened to the flip cover by rivets. The cap ends are located below the top wall of the heating body. The heating cavity of the heating device is fitted onto the pressing chamber, and the heating body is bolted to the flip cover by the screws. This ensures effective installation between the heating device and the oil press and prevents the heating device from moving along the axis of the pressing chamber during use.
[0020] Preferably, the device also includes a spring. The screw is slidably connected to the top wall of the heating body, and the spring is sleeved on the screw. The two ends of the spring respectively abut against the two panels of the top wall of the heating body opposite to the flip-top cover. Vibration inevitably occurs in the pressing chamber during operation. The screw can slide up and down along the top wall of the heating body. The screw, in conjunction with the spring, can absorb the energy generated during the vibration of the pressing chamber, ensuring the stable and efficient operation of the oil press.
[0021] Preferably, the screw end has a threaded hole, and the rivet passes through the top surface of the flip cover and is anchored in the threaded hole. The detachable connection facilitates the assembly of the heating element and the oil press.
[0022] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a heating device and an oil press having the same. The heating device can achieve 360-degree circumferential heating of the pressing chamber, ensuring that the heat loss of the oil press is extremely low during continuous and efficient operation, significantly improving the heat transfer efficiency, improving the quality of oil pressing and the oil yield, while also saving the installation process of the heat-conducting aluminum sleeve, simplifying the production process, and improving the overall flexibility and ease of use of the heating device.

[0030] 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.
[0031] Example 1:
[0032] See appendix Figures 1-2 This utility model discloses a heating device, including a heating body 1, a heat-conducting core 2, and a heating element 4;
[0033] The bottom wall of the heating body 1 is provided with a sliding groove 11 that runs through both end faces of the body, and the top wall of the body is provided with an assembly groove 12; the heat-conducting core 2 is slidably connected in the sliding groove 11, and there is a heating cavity between the top wall of the heat-conducting core 2 and the inner wall of the bottom of the sliding groove 11.
[0034] The heating element 4 is inserted into the assembly slot 12 to provide heat to the heating cavity through the heating body 1; the cover plate 3 is detachably connected to the top surface of the heating body 1 to cover the heating element 4.
[0035] like Figure 2 As shown, the heating element is the heat source, and the heat-conducting core can conduct heat. The heating element transfers heat to the heating body, and the heating body and the heat-conducting core can transfer heat to the heating cavity. The heating device is installed on the equipment to be heated through the heating cavity. The heating element and the heating body can be connected by a drawer-type structure. The heating element can be replaced and installed by pulling it out. The heat-conducting core and the heating body can also be disassembled. The detachable connection of the heating device makes it easy to install and disassemble, and more convenient to use.
[0036] To further optimize the above technical solution and ensure that the heat-conducting core does not undergo axial displacement along the slide groove after the heating device is installed with the equipment to be heated, a limiting plate 5 is also included. One end of the limiting plate 5 is hinged to one side wall of the heating body 1, and the other end can abut against one side end face of the heat-conducting core 2 to limit its axial sliding relative to the slide groove 11.
[0037] In order to further optimize the above technical solution, ensure that the heat-conducting core can slide effectively along the slide groove, and improve the connection effect between the heat-conducting core and the heating body, a locking block 14 is fixed on the inner side wall of the opening end of the slide groove 11, and the top surface of the locking block 14 slides against the bottom surface of the heat-conducting core 2.
[0038] In this embodiment, a first engaging cavity 21 is formed on the top surface of the heat-conducting core 2, and a second engaging cavity 13 is formed on the inner top wall of the heating body 1 relative to the sliding groove 11. The first engaging cavity 21 and the second engaging cavity 13 engage with each other to form a heating cavity. The heating cavity can be circular, square, or trapezoidal, but is not limited to these three shapes.
[0039] A heating cavity is formed by a heat-conducting core and a heating body. The shape of the heating cavity is consistent with the shape of the equipment to be heated, enabling 360° all-around heating of equipment of different shapes.
[0040] In some other specific embodiments, such as Figure 2 As shown, the assembly slot can be opened on the top surface of the heating body, and also includes a cover plate 3. The top surface of the heating body 1 is open relative to the assembly slot 12, and the cover plate 3 is bolted to the top surface of the heating body 1 to cover the heating element 4. The heating element can be replaced by removing the cover plate.
[0041] Example 2:
[0042] See appendix Figure 3 and 4This utility model embodiment provides an application of a heating device in an oil press. The oil press 8 includes a housing 83, a flip cover 82, and a pressing chamber 81. The flip cover 82 is hinged to an outer side wall of the housing 83. The pressing chamber 81 is located below the flip cover 82, with one end fixed to the outer side wall of the housing 83 and the other end penetrating through the heating cavity.
[0043] In this embodiment, there are multiple screws 6. The ends of the multiple screws 6 penetrate vertically through the top wall of the heating body 1 and are fastened to the flip cover 82 by rivets. The cap ends are located below the top wall of the heating body 1.
[0044] During installation, the heating element can be inserted into the assembly slot of the heating body first. The top wall of the heating body and the flip cover are connected by rivets and screws. The second fastening cavity is fastened to the upper part of the pressing chamber. The heat-conducting core is then slid into the heating body from the slide groove, while ensuring that the first fastening cavity is fastened to the lower half of the pressing chamber. The limiting plate is flipped to restrict the heat-conducting core in the slide groove, thus completing the assembly of the heating device and the pressing chamber.
[0045] To further optimize the above technical solution, a threaded hole is provided at the end of the screw 6, and the rivet passes through the top surface of the flip cover 82 and is anchored in the threaded hole. The rivet and the screw are detachably connected. By removing the rivet and pulling out the screw, and flipping the flip cover at a certain angle, the heating element can be replaced after removing the cover plate.
[0046] To further optimize the above technical solution and make the heating device have a certain shock absorption effect, a spring 7 is also included. The screw 6 is slidably connected to the top wall of the heating body 1. The spring 7 is sleeved on the screw 6. The two ends of the spring 7 respectively abut against the two panels opposite to the top wall of the heating body 1 and the flip cover 82.
[0047] The pressing chamber will vibrate during use. A certain gap can be reserved between the nut end of the screw and the cover plate. The screw is fastened to the flip cover by rivets. During the vibration of the pressing chamber, the screw will slide up and down along the cover plate to offset the vibration energy. When used with a spring, the heating device can have a shock absorption effect.
[0048] In some other specific embodiments, the heating element is replaced by removing the cover plate. The cover plate is bolted to the top wall of the heating body. The area of the cover plate is larger than the top surface area of the heating body. The part of the cover plate that protrudes from the top wall of the heating body has a through hole. The end of the screw rod passes through the through hole and is fastened to the flip cover by rivets.
[0049] The screw can slide up and down along the through hole of the cover plate. The spring is sleeved on the outer wall of the screw between the cover plate and the flip cover, and provides shock absorption through the spring and the screw.
