Description

Technical Field

[0001] The utility model relates to a heat dissipation and noise reduction device for a screw oil press, belonging to the technical field of screw oil presses. Background Art

[0002] The screw oil press utilizes the principle of screw extrusion. Through the rotation of the screw shaft, the oil material is extruded against the inner wall of the pressing chamber, thereby promoting the rupture of oil cells and the outflow of oil from the cells. During the operation of the screw oil press, due to the high-pressure extrusion and friction between the screw shaft, the material and the pressing chamber, as well as changes in the characteristics of the material such as particle size and fiber content, there is a mechanical interaction between the screw shaft and the material and vibration of the screw shaft, resulting in a large amount of noise, which causes great damage to the hearing of operators. In addition, this extrusion and friction also generate a large amount of heat, causing a continuous increase in the temperature of the equipment itself and the surrounding environment. The continuous high temperature will reduce the quality of the oil and also affect the physical functions of the operators.

[0003] Currently, as disclosed in the patent application No. CN202022151545.6, a base for an oil press with shock absorption and noise reduction functions is provided, including a shaft seat, and further including a first shock absorption arc sleeve and a second shock absorption arc sleeve sleeved outside the shaft seat. The first shock absorption arc sleeve and the second shock absorption arc sleeve are both two semi-circular arc structures symmetrically installed outside the shaft seat. The internal structures of the first shock absorption arc sleeve and the second shock absorption arc sleeve are the same. An activity cavity is provided inside the second shock absorption arc sleeve. A first arc lever and a second arc lever are symmetrically arranged inside the activity cavity. A shock absorption airbag is slidably embedded inside the activity cavity and outside the second shock absorption arc sleeve. The shock absorption airbag includes a first side airbag and a middle airbag connected to both ends of the second arc lever. One end of the first arc lever is connected to a second side airbag, and the other end is connected to the bottom of the middle airbag.

[0004] However, although the above technology provides a base for an oil press with shock absorption and noise reduction functions, it not only does not consider the heat dissipation problem during the shock absorption and noise reduction process, but also is not convenient for the disassembly, cleaning and maintenance of the base itself and the screw oil press because it cannot reduce the temperature of the equipment itself and the surrounding environment. Therefore, there is an urgent need to find a detachable heat dissipation and noise reduction device for a screw oil press to reduce the noise transmission and temperature rise generated during the operation of the screw oil press, and reduce the health hazards to operators during the operation of the screw oil press. Summary of the Utility Model

[0005] To solve the above problems, the utility model provides a heat dissipation and noise reduction device for a screw oil press, including:

[0006] The housing includes a shell with an "n"-shaped cross-section, a top structure connected to the top of the shell, and a bottom structure connected to the bottom of the shell. The top structure includes an inner curved panel closedly connected to the shell and a top sound-absorbing cavity formed between the shell and the inner curved panel. The bottom structure includes an inner flat panel closedly connected to the shell through a partition and a bottom sound-absorbing cavity formed between the shell and the inner flat panel. The top structure also has ventilation holes penetrating the shell, the top sound-absorbing cavity, and the inner curved panel.

[0007] A fixing clip connects the housing and the feed hopper of the screw oil press.

[0008] At least one shock-absorbing device is installed above the inner flat panel and below the inner curved panel, and a heat dissipation cavity communicating with the ventilation holes is formed between the shock-absorbing device and the inner curved panel.

[0009] Furthermore, an exhaust fan is provided in the ventilation holes.

[0010] Furthermore, the top sound-absorbing cavity and the bottom sound-absorbing cavity are both filled with sound-absorbing glass wool, which is a sound-absorbing material with characteristics such as heat insulation and non-flammability. The inner curved panel and the inner flat panel are both provided with a plurality of sound-absorbing through holes.

[0011] Furthermore, the shock-absorbing device includes a top plate, a bottom plate, a contact plate, a damping rod, and a sliding rod arranged in sequence from outside to inside. The damping rod connects the top plate and the contact plate and penetrates the bottom plate. The sliding rod connects the bottom plate and the contact plate and cooperates with the damping rod. A sliding cavity is formed between the top plate and the bottom plate to allow the sliding rod to slide relatively along the damping rod. The contact plate is closely attached to the oil pressing chamber of the screw oil press.

[0012] Among them, the "outside" refers to the outer half of the space outside the housing, and the "inside" refers to the space area inside the housing.

[0013] In an embodiment of the present invention, the top plate and the bottom plate are both provided with a plurality of heat dissipation through holes.

[0014] Furthermore, the bottom plate has limit blocks restricted on both sides of the sliding rod.

[0015] Furthermore, the damping rod is connected to the contact plate through a spring and a hanging ear in sequence, and the material of the contact plate is heat-resistant rubber.

[0016] Furthermore, the fixing clip has a rubber gasket and an adjusting knob.

[0017] The beneficial effects of the present invention:

[0018] 1. By fixing the fixing clip to the feeding funnel of the screw oil press, the present utility model ensures the stability of a detachable screw oil press heat dissipation and noise reduction device during use. At the same time, after the screw oil press finishes working, by loosening the fixing clip, the device can be removed from the screw oil press, facilitating the maintenance of the oil press and the device. In addition, since the tightening range of the fixing clip is adjustable, it is adaptable to the feeding funnels of screw oil presses of different sizes to a certain extent, further improving the versatility of the device.

[0019] 2. The present utility model sets the contact plate of the shock absorption device to contact the pressing chamber of the screw oil press. When the screw oil press is working, the vibration force generated will push the slide bar connected to the contact plate to move along the direction of the damping rod within the limit block. At the same time, the spring arranged between the damping rod and the contact layer is compressed, converting a part of the mechanical energy into elastic potential energy, thereby reducing the vibration feeling of the pressing chamber of the screw oil press and greatly reducing the noise caused by the mechanical interaction between the screw and the material and the vibration of the screw due to the high-pressure extrusion and friction between the screw, the material and the pressing chamber, as well as the changes in the characteristics of the material such as the particle size and fiber content.

[0020] 3. The present utility model sets the sound absorption through holes arranged inside the cover body to communicate with the top sound absorption cavity and the bottom sound absorption cavity, thereby transmitting the noise generated when the screw oil press is working from the equipment to the sound absorption cavity. The sound absorption glass wool filled in the sound absorption cavity can effectively block the transmission of noise to the external environment. In addition, the exhaust fan is located at the top of the device and is connected to the heat dissipation cavity. The heat dissipation cavity is located between the top sound absorption cavity and the shock absorption device, and the top plate and bottom plate of the shock absorption device are provided with heat dissipation through holes. Thus, due to the blowing effect of the exhaust fan, the heat generated by the extrusion and friction when the screw oil press is working is discharged from the screw oil press body through the heat dissipation through holes to the heat dissipation cavity, and then is discharged by heat exchange along the inner cavity direction of the heat dissipation cavity by the exhaust fan.

[0021] Generally speaking, the present utility model not only realizes the technical effect of shock absorption and noise reduction for the pressing chamber of the screw oil press, but also achieves the purpose of heat dissipation and ventilation. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] As Figures 1 - 5 shown, the present utility model provides a heat dissipation and noise reduction device for a screw oil press, including:

[0033] The cover body 1 includes a housing 101 with an "n"-shaped cross-section, a top structure connected to the top of the housing 101, and a bottom structure connected to the bottom of the housing 101.

The top structure also has ventilation holes that penetrate through the housing 101, the top sound-absorbing cavity 9, and the inner curved panel 1021.

[0034] The fixing clip 2 connects the cover body 1 and the feed hopper of the screw oil press.

[0035] A plurality of shock-absorbing devices 7 are provided. The shock-absorbing devices 7 are installed above the inner flat panel 1022 and below the inner curved panel 1021. A heat dissipation cavity 8 that communicates with the ventilation holes is formed between the shock-absorbing devices 7 and the inner curved panel 1021.

[0036] Furthermore, an exhaust fan 11 is provided in the ventilation holes for discharging the heat generated in the oil pressing chamber to the external environment successively through the heat dissipation through holes 6, the heat dissipation cavity 8, and the ventilation holes. The heat dissipation cavity 8 is used for heat collection and heat dissipation and exhaust air diversion.

[0037] Furthermore, both the top sound-absorbing cavity 9 and the bottom sound-absorbing cavity 5 are filled with sound-absorbing glass wool for absorbing the noise generated during the operation of the screw oil press. A plurality of sound-absorbing through holes 4 are provided in both the inner curved panel 1021 and the inner flat panel 1022 for transmitting the noise generated during the operation of the screw oil press into the top sound-absorbing cavity 9 and the bottom sound-absorbing cavity 5.

[0038] Furthermore, the shock-absorbing device 7 includes a top plate 704, a bottom plate 707, a contact plate 701, a damping rod 706, and a sliding rod 705 that are arranged in sequence from outside to inside. The damping rod 706 connects the top plate 704 and the contact plate 701 and penetrates through the bottom plate 707. The sliding rod 705 connects the bottom plate 707 and the contact plate 701 and cooperates with the damping rod 706. A sliding cavity 703 is formed between the top plate 704 and the bottom plate 707, allowing the sliding rod 705 to slide relative to the damping rod 706. The contact plate 701 is in close contact with the oil pressing chamber of the screw oil press. As Figure 3 shown, the top plate 704, the bottom plate 707, and the contact plate 701 are all curved panels.

[0039] Both the top plate 704 and the bottom plate 707 are provided with a plurality of heat dissipation through holes 6.

[0040] Further, the bottom plate 707 is provided with limit blocks 708 restricted on both sides of the slide bar 705 to prevent the slide bar 705 from being misaligned during the sliding process.

[0041] Further, the damping rod 706 is connected to the contact plate 701 through a spring 702 and a hanging ear in sequence. The contact plate 701 is made of heat-resistant rubber, avoiding frictional losses caused by mechanical vibration.

[0042] Further, the fixing clip 2 is provided with a rubber washer 202 and an adjusting knob 203. After the adjusting knob 203 adjusts the tightness of the fixing clip, the current clamping position can be fixed by adjusting the nut 201; the rubber washer 202 is used to closely fit with the feed hopper of the screw oil press, and at the same time reduce the mechanical frictional loss between the feed hopper and the fixing clip 2.

[0043] Embodiment 2

[0044] This embodiment demonstrates the working principle of Embodiment 1:

[0045] First, tighten the adjusting knob 203 of the fixing clip 2 to clamp and fix it to the feed hopper of the screw oil press. At the same time, a proper number of shock absorption devices 7 are horizontally installed on the pressing chamber of the screw oil press. Then, turn on the power switch 3 to start the exhaust fan 11. When the screw oil press is working, the generated vibration force will push the slide bar 705 connected to the contact plate 701 to move along the direction of the damping rod 706 within the limit block 708. At the same time, the spring 702 arranged between the damping rod 706 and the contact plate 701 is compressed, converting a part of the mechanical energy into elastic potential energy, thereby reducing the vibration feeling of the pressing chamber of the screw oil press and greatly reducing the noise caused by the mechanical interaction between the screw and the material and the vibration of the screw due to the high-pressure extrusion and friction between the screw, the material and the pressing chamber, and the changes in the characteristics of the material such as the particle size and fiber content; the noise that cannot be eliminated by the shock absorption device 7 will be transmitted to the top sound absorption cavity 9 and the bottom sound absorption cavity 5 respectively through the sound absorption through holes 10 of the top sound absorption cavity and the sound absorption through holes 4 of the bottom sound absorption cavity. The sound absorption material filled in the sound absorption cavity can effectively block the transmission of noise to the external environment; in addition, the exhaust fan 11 is connected to the heat dissipation cavity 8. Due to the blowing effect of the exhaust fan 11, the heat generated by the extrusion and friction during the operation of the screw oil press can be discharged from the screw oil press body through the heat dissipation through holes 6 into the heat dissipation cavity 8, and then heat-exchanged and discharged from the ventilation holes by the exhaust fan 11; when the screw oil press stops working, first turn off the power switch 3, so that the exhaust fan 11 stops working. Finally, loosen the adjusting knob 203 of the fixing clip 2 to remove the cover body 1 as a whole from above the screw oil press, realizing a detachable heat dissipation and noise reduction device for the screw oil press.

[0046] Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model.
