Description

Technical Field

[0001] The utility model relates to the field of oil pressing equipment, in particular to a new type of multifunctional oil press. Background Art

[0002] An oil press refers to a machine that extrudes oil from oilseeds with the help of mechanical external force. The structure of an oil press generally includes an electric control console (control box), a motor reduction mechanism, a pressing shaft, a pressing screw, a pressing chamber, a pressing cage, a feed hopper, etc. During operation, the motor reduction mechanism drives the reduction gear at the left end of the pressing shaft to rotate (the pressing screw is transversely and tightly sleeved and welded on the outside of the pressing shaft, the pressing screw is located in the pressing chamber (divided into a front pressing chamber and a rear pressing chamber), the pressing chamber is located in the pressing cage, and the left end of the pressing shaft is tightly sleeved in the end reduction gear of the motor reduction mechanism), and then the pressing shaft drives the pressing screw tightly sleeved on the outside of the pressing shaft to rotate. After the pressing screw rotates, the raw materials in the feed hopper at its upper right end are continuously conveyed from right to left into the pressing chamber (the pressing screw and the pressing chamber are in conformity in shape and there is a certain distance between the two). Since the distance between the pressing shaft and the inner side of the pressing chamber is small, the oil in the continuously pressed raw materials will be extruded and flow out from the gaps of several pressing bars on the surface of the ring pressing chamber. The raw material cake after the oil is extracted is discharged from the left front end of the pressing chamber.

[0003] Although the existing oil presses meet the production needs to a certain extent, due to structural limitations, there are still the following technical problems. First: The left side of the central shaft of the pressing shaft is rotatably connected to the left side shaft hole in the pressing chamber. To facilitate the cleaning of the pressing shaft, etc., the right end of the central shaft of the pressing shaft is connected to the right side limit in the pressing chamber through a positioning sleeve. Specifically, the right end of the central shaft is rotatably sleeved in the hollow shaft hole of the positioning sleeve, and the positioning sleeve is installed on the right side in the pressing chamber (with internal threads) by external thread method. When connecting the positioning sleeve by thread method, affected by processing accuracy and long-term removal and installation of the positioning sleeve, etc. (and the pressing shaft is subjected to large acting forces during operation), after the external thread and internal thread are worn, due to the poor fit and looseness between the positioning sleeve and the pressing chamber, the probability of eccentricity will occur when the pressing shaft rotates, resulting in a large wear gap between the pressing shaft and the pressing chamber and a decrease in the oil output. When the wear is too large, it is necessary to replace the positioning sleeve, the pressing shaft and the pressing chamber, etc., bringing unnecessary economic losses to the manufacturer. Second: The outer diameter of the screw on the pressing shaft gradually increases from right to left. When the raw materials (such as beans, rapeseed, etc.) are pushed leftward into the pressing chamber by the screw on the pressing shaft for oil pressing, since the center part of the raw materials does not contact the outer side of the screw and the inner side of the pressing chamber after being pressed into a cake shape, the raw materials in the cake-shaped raw materials cannot be effectively pressed out, which will have an adverse impact on the oil output rate of the raw materials. Third: It does not have a weighing function. It is necessary to place the oil barrel on the platform scale for weighing after the oil pressing is completed. The above method will bring inconvenience to the staff and is not conducive to improving work efficiency. Fourth: It does not have the function of cooling and heating the pressed oil. In fact, when pressing oil (especially when the oil press is in the cold pressing oil mode), the initial part of the oil pressed at the beginning of equipment startup has poor fluidity due to the low temperature in the equipment (especially more obvious in cold winter), and the impurities in the oil are mixed with the oil, which is not conducive to the subsequent filtering process, resulting in a slow filtering process speed, and the fine impurities in the oil are mixed with the oil and are not easy to separate, and it will also cause the filtered oil to be turbid. The existing relatively advanced method is to install an electric heating tube at the lower end of the oil receiving tray for heating, so that the oil flowing from the pressing cage to the oil receiving tray is heated. However, since this method is in a static heating mode of the oil receiving tray, it is easy to cause impurities in the oil to precipitate on the oil receiving tray, overheating and burning to cause the oil quality to deteriorate and have peculiar smells, etc.; after the oil press works for a period of time, since the temperature in the equipment rises and heating is no longer required, and the oil temperature is usually higher than 100 °C, when the pressed oil enters the sedimentation tank and water is added after filtration (the purpose of adding water is mainly to improve the purity and color of the oil and separate impurities. Specifically, the density of water is greater than the density of oil. When water and oil are stirred and mixed evenly, water molecules can fully absorb the fine impurities in the oil, and then water and impurities precipitate at the bottom of the sedimentation tank, and the oil is located above the water layer, ensuring the quality of the oil produced in the subsequent terminal production), due to the too high temperature, it will cause the initial water to boil and the oil to overflow outside the sedimentation tank, and even the steam will scald the staff, etc., there are great safety hazards; although it is possible to wait for the oil temperature in the sedimentation tank to decrease before adding water, the above method increases the production time of the oil and is not conducive to improving work efficiency. Summary of the Invention

[0004] In order to overcome the disadvantages of the existing oil press due to its structure limitations as described in the background, the present utility model provides a new type of multifunctional oil press. The left side of the positioning sleeve and the right inner side of the oil pressing chamber are not only connected by threads, but also positioned and connected in a bushing - type manner, which can play a better positioning role between the left side of the positioning sleeve and the inner side of the oil pressing chamber, reducing the probability of eccentricity of the oil pressing shaft during operation. The outer diameters of multiple sets of screw presses on the oil pressing shaft decrease successively between adjacent ones, enabling the cake - shaped raw materials to be dispersed when entering this area. After dispersion, the raw materials can be alternately pressed by the next - level screw presses as much as possible, improving the oil yield. It can conveniently weigh the oil in the barrel body and barrel A, and can also heat or cool the crude oil extracted according to the required stirring method, improving the filtering effect of the crude oil and preventing various problems caused by adding water when the oil temperature is too high.

The power input terminals of the oil pump, solenoid valve, and solenoid valve A are respectively connected to the two poles of an AC 220V power supply through a power switch and wires; The display 21 supporting the tension sensor is installed in the electric control box of the oil press body 1 (the display surface is located at the front outer side of the electric control box); The electric stirring mechanism includes a housing 51, a motor, a driving pulley (not shown in the figure), a transmission belt (not shown in the figure), a driven pulley (not shown in the figure), a stirring shaft 52, stirring blades (not shown in the figure), and bearing seats 53. A partition 6 is welded at the lower end position of the oil receiving tray 106 of the oil press body. The upper ends of the two stirring shafts 52 are respectively tightly sleeved in the inner rings of the bearings of the two sets of bearing seats 53. The two stirring blades are respectively welded to the lower sides of the stirring shafts 52. The two sets of driven pulleys 51 are respectively fixedly installed on the upper parts of the two stirring shafts 52 and below the bearing seats 53.

[0016] Figure 1 , 2 , as shown in 3, the inner diameter of the limit ring 103 is the same as the inner diameter of the oil press chamber 104 at the left side position of the positioning ring 101. The outer diameter of the limit ring 103 is slightly smaller than the inner diameter of the positioning ring 101 (the two are in a tightly rotating and combined state). The solenoid valve is a normally closed spool solenoid valve. The barrels 31 and barrel A41 are respectively placed at the lower ends of the two stirring blades of the electric stirring mechanism, and there are intervals between the lower ends of the stirring blades and the inner lower ends of the barrels 31 and barrel A41, and there are intervals between the stirring blades and the inner sides of the cooling pipe and the heating pipe. A rotating oil outlet tray 1061 is rotatably installed at the front side end of the oil receiving tray 106 of the oil press body, and the oil outlet tray can rotate clockwise or counterclockwise in the oil receiving position. When rotating clockwise, the oil outlet 1061 is located outside the middle of the upper end of the barrel 31. When rotating counterclockwise, the oil outlet tray 1061 is located outside the rear part of the upper end of the barrel A41. The two rear ends of the housing 51 and the upper left and right side ends of the partition 6 are installed together through a connecting plate 107.

[0017] Figure 1 、 2 As shown in 3, this new type is based on the oil press body. During operation, the motor reduction mechanism drives the reduction gear at the left end of the pressing shaft 104 to rotate (the pressing screw 105 is transversely and tightly sleeved and welded on the outside of the pressing shaft 104. The pressing screw 105 is located in the pressing chamber 102 (divided into a front pressing chamber and a rear pressing chamber). The pressing chamber is located in the pressing cage. The left end of the pressing shaft is tightly sleeved in the reduction gear at the end of the motor reduction mechanism)), and then the pressing shaft 104 drives the pressing screw 105 tightly sleeved on the outside of the pressing shaft to rotate. After the pressing screw 105 rotates, it continuously conveys the raw materials in the feeding bin 108 hopper at its upper right end into the pressing chamber 102 from right to left (the pressing screw 105 and the pressing chamber 102 are in conformity in shape and there is a certain distance between them). Since the distance between the pressing shaft 105 and the inner side of the pressing chamber 102 is small, the oil in the continuously pressed raw materials will be extruded out and flow out from the gaps between several pressing bars on the surface of the annular pressing chamber. The raw material cake after oil pressing is discharged from the left front end of the pressing chamber. The squeezed oil falls into the oil receiving tray 106 at the lower end of the pressing chamber 102 and then flows out into the barrel 31 or the barrel A41 (the staff manually rotates the oil outlet tray 1061 clockwise outside the middle part at the upper end of the barrel 31 and rotates the oil outlet tray 1061 counterclockwise outside the middle part at the upper end of the barrel A41). In this new type, not only are the left side of the positioning sleeve and the right inner side of the pressing chamber connected by threads, but also they are positioned and connected by a bushing method (the limiting ring 103 is sleeved in the positioning ring 101). A better positioning effect can be achieved between the left side of the positioning sleeve and the inner side of the pressing chamber 102, reducing the probability of eccentricity of the pressing shaft 104 during operation, enabling the equipment to work stably and reliably, and improving the oil yield. The outer diameter of the part 1051 between every two adjacent sections of the pressing screw 105 in this new type is smaller than the outer diameters of the two sections of the pressing screw 105, so that when the cake-shaped raw materials enter this area, a dispersing effect can be achieved (the sudden increase in space can be dispersed under the action of the rotating pressing screw 105). After dispersion, the raw materials can be as fully and alternately pressed by the next-stage pressing screw as possible, improving the oil yield (the measured oil yield can be increased by 0.6 - 1.8%).

[0018] Figure 1 、 2, as shown in FIGS. 3, when extracting oil in the prior art (especially when the oil press is in the cold pressing mode), the initial part of the oil extracted at the start-up of the equipment has poor fluidity due to the low temperature inside the equipment (more obvious especially in cold winters), and the impurities in the oil are mixed with the oil, which is not conducive to the subsequent filtration process. It will cause the filtration process to slow down, and the fine impurities in the oil are mixed with the oil and are not easily separated, and it will also cause the filtered oil to be turbid). Specifically, in the present invention, the staff turns on the power switches of the electric heating tube and the electric stirring mechanism, and rotates the oil outlet tray on the side of the oil receiving tray to be located outside the upper end of the barrel A41. The electric heating tube 42 is powered on to heat the oil that subsequently enters the barrel A41, and the oil pumped into the upper end filter screen in the precipitation tank by the oil pump later can be heated up, preventing the occurrence of the above problems; during the heating process, since the motor drives the two stirring blades to rotate through the driving pulley, the transmission belt, and the driven pulley, stirring and heating the oil in the barrel A41, so the problem that the impurities in the oil sink to the bottom of the barrel A41 and are overheated and burned, which has an adverse impact on the quality of the oil, is prevented (turn off the power switches of the electric heating tube and the electric stirring mechanism when not using the heating function). When extracting oil in the prior art, after the oil press works for a period of time, since the temperature inside the equipment rises and heating is no longer required, and the oil temperature is usually higher than 100 °C, when the extracted oil enters the precipitation tank and water is added during filtration (the purpose of adding water is mainly to improve the purity and color of the oil and separate impurities. The density of water is greater than that of oil. When water and oil are stirred and mixed evenly, water molecules can fully absorb the fine impurities in the oil, and then water and impurities precipitate at the bottom of the precipitation tank, and the oil is located above the water layer, ensuring the quality of the oil produced in the subsequent terminal). Due to the too high temperature, it will cause the initial water to boil and the oil to overflow outside the precipitation tank, etc., and even the steam will scald the staff, posing a great safety hazard; although it is possible to wait for the oil temperature in the precipitation tank to decrease before adding water, the above method increases the production time of the oil and is not conducive to improving work efficiency. Specifically, in the present invention, the staff turns on the power switch of the electric stirring mechanism (and opens the valve of the tap water pipeline), and rotates the oil outlet tray on the side of the oil receiving tray to be located outside the middle of the upper end of the barrel 31. In this way, cooling water will enter the cooling pipe 32 (spirally wound with multiple layers in a snake shape), and after absorbing heat, the cold water flows out to the waste water tank. During the cooling process, since the motor drives the stirring blades to rotate through the driving pulley, the transmission belt, and the driven pulley, stirring and dissipating heat from the oil in the barrel 31, so the oil temperature is effectively reduced (the oil temperature output to the oil pump is about 85 °C), enabling the subsequent addition of water to the precipitation tank and the stirring and mixing of the water and the oil, and the work of precipitating water and impurities at the bottom of the precipitation tank can proceed smoothly (when treating crude oil and adding a certain proportion of water, it can also achieve the effect of dephosphorization. Since the present invention can measure and control the weights of the crude oil and water, it can accurately dephosphorize).

[0019] Figure 1 , 2, as shown in Figures 3, when oil continuously flows into the barrel body 31 or the barrel body A41, its weight will increase, and the gravity detected by the first set or the second set of tension sensors 2 will increase. In this way, the staff can conveniently know the amount of oil in the barrel body 31 and the barrel body A41 through the display 21 equipped with the first set or the second set of tension sensors (electronic scales). Specifically, the electronic scale can directly measure the weight of the crude oil, and the staff can calculate how much water needs to be added according to the mixing ratio and display it on the display screen. When the oil quantity is appropriate, the staff turns on the power switch of the corresponding solenoid valve (the spool opens when powered) and the oil pump. When the oil pump is powered on, it will pump the oil in the barrel body 31 or the barrel body A41 into the sedimentation tank (entering the sedimentation tank through the filter screen). Through the above technical solution, the present invention reduces the probability of eccentricity during the operation of the squeezing shaft, improves the oil yield, can also heat or cool the squeezed crude oil according to the required stirring method, improves the filtering effect of the crude oil, and prevents various problems caused by adding water when the oil temperature is too high. The tension sensor 2 is a finished product of a tension sensor display of model ZNLBS, which is equipped with a set of voltage stabilizing modules (AC 220V to DC 8V power supply modules). The power input terminal of the voltage stabilizing module and the two poles of the AC 220V power supply are respectively connected by wires, and the power output terminal of the voltage stabilizing module and the power input terminal of the tension sensor are respectively connected by wires; the power of the electric heating tube 42 is 4KW; the power of the motor is 2KW; the power of the oil pump is 1.2KW.
