Description

Technical Field

[0001] The utility model relates to the technical field of oil extraction equipment, in particular to a double-helix reverse stirring device. Background Art

[0002] Walnut kernels and peanut kernels are raw materials for oil extraction. Usually, the raw materials can be placed in an oil extraction machine for oil extraction. When extracting oil, the grinding mechanism is first required to crush the walnut kernels and peanut kernels into suitable small particles, and then the ground powder is heated by the heating mechanism. In this process, the raw materials can be placed in the stirring mechanism of the oil extraction machine, and the powder is fully stirred to make it evenly heated. In actual use, the existing stirring mechanism used for oil extraction can use a reverse spiral stirring device to evenly stir the powder, thereby improving the uniformity of heating. However, the reverse spiral stirring device will contain some residual materials that are not completely discharged during long-term use, and the heating of walnuts and peanuts will also cause oil to be contained in the device. Therefore, relevant personnel are often required to clean it regularly. Manual cleaning is time-consuming and labor-intensive, which is not conducive to actual use. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 The utility model discloses a double-helix reverse stirring device, comprising a double-helix stirrer 1, wherein two rotating ends of the double-helix stirrer 1 are provided with a transmission device 2, and the other end of the transmission device 2 is provided with two lead screws 3, wherein the thread directions of the two lead screws 3 are consistent, and the double-helix stirrer 1 will drive the two lead screws 3 to rotate relative to each other when working, and a cleaning scraper 4 is slidably installed on the inner side of the double-helix stirrer 1, and a water spray moving device 5 is installed on the top of the cleaning scraper 4, and the cleaning scraper 4 is used to scrape off the residual material on the inner wall of the double-helix stirrer 1.

[0023] In one embodiment, the water spray moving device 5 includes a diverter box 51 with two water outlets, a valve body 53 connected to one of the water outlets of the diverter box 51, and a retractable linkage plug 55 installed on opposite sides of the valve body 53, and a valve core 54 rotatably installed on the inner side of the valve body 53. The valve body 53 is equipped with interconnected water spray pipes 57, and the valve core 54 divides the valve body 53 into multiple spaces. The valve core 54 rotates to make the water in the valve body 53 flow to different spaces. When water enters different spaces, it will push one of the linkage plugs 55 to move laterally outside the valve body 53 to make it close to the screw 3, or make the water flow into the water spray pipe 57.

[0024] In a specific implementation, an external water source is connected to the water inlet of the diverter box 51 through a water pump. When the inside of the double-helix agitator 1 needs to be cleaned, water is connected to the valve body 53, and the valve core 54 is rotated to make the water in the valve body 53 flow into different spaces. When the water flows to the space connected to one of the linkage inserts 55, the water will squeeze the linkage insert 55 to move it to the outside of the valve body 53. During the movement, the linkage insert 55 will approach, contact and insert into the threaded concave part of one of the lead screws 3. As the lead screw 3 rotates, the double-helix agitator 1 is driven to clean. The cleaning scraper 4 which cannot rotate in the mixer 1 moves along one side of the conveying direction of the double-helix mixer 1, and the cleaning scraper 4 will scrape off the solid impurities around the inner wall of the double-helix mixer 1. At the same time, the water in the diversion box 51 will flow from the second water outlet to the water guide pipe 52, and then be transmitted to the water spray pipe 57. The water is finally sprayed from the water spray pipe 57 into the double-helix mixer 1, and cooperates with the movement of the cleaning scraper 4 to further clean the impurities and oil in the double-helix mixer 1, and the mixture is finally discharged from the discharge port of the double-helix mixer 1.

[0025] It should be noted that the water in the control valve body 53 flows to the space connected to the other linkage plug 55, so that the water pushes the other linkage plug 55 to move outward. At this time, the first linkage plug 55 is not pushed by water, and the reset spring 56 squeezes the linkage plug 55 to reset it, and the second linkage plug 55 approaches and is inserted into the threaded recess of the other screw 3, thereby driving the cleaning scraper 4 to move along the other side of the conveying direction of the double-helix agitator 1. This can effectively improve the internal cleaning efficiency of the double-helix agitator 1. At the same time, the clean water of the external water source can be replaced by an efficient degreasing detergent, thereby ensuring the cleaning efficiency of the double-helix agitator 1.

[0026] It is understandable that when it is not necessary to make all the linkage inserts 55 and the lead screw 3 to be adjusted in linkage, the valve core 54 can be rotated to make the remaining water in the valve body 53 flow to the water spray pipe 57, so that the water can be discharged.

[0027] In one embodiment, the double-helix agitator 1 includes a shell 11, a motor 12 mounted on the shell 11, a gear box 13 mounted on the shell 11, and two augers 14 connected to two output ends of the gear box 13, wherein the cleaning scraper 4 is used to scrape off the residual material on the inner wall of the shell 11, the rotating shaft of the motor 12 is connected to the input end of the gear box 13, and the gear box 13 has two output ends with opposite directions, and the two augers 14 are relatively installed in the shell 11, and the two augers 14 are driven by the motor 12 to rotate in opposite directions.

[0028] In a specific implementation, the transmission device 2 is installed at the other end of the auger 14 away from the gear box 13, and the transmission device 2 can be composed of a housing, a sprocket and a chain. There are two sprockets and they are respectively installed on the screw 3 and the auger 14. The chain is connected to the two sprockets. When the auger 14 rotates, the sprocket and the chain cooperate to make the screw 3 rotate synchronously, thereby facilitating the subsequent driving of the water spraying mobile device 5 to work.

[0029] In one embodiment, two linkage plugs 55 and a water spray pipe 57 are distributed on the valve body 53 in the form of an isosceles triangle, and the two linkage plugs 55 and the water spray pipe 57 are respectively connected to one of the spaces inside the valve body 53. The valve core 54 is circular, and its surface has a plurality of sheet structures protruding outward. The other side of the sheet structure and the inner diversion box 51 of the valve body 53 conduct the water flowing into the valve body 53 to the linkage plug 55 or the water spray pipe 57. When the linkage plug 55 does not need to be used in conjunction with the screw 3, the valve core 54 is driven to rotate so that the water there can flow to the water spray pipe 57.

[0030] In one embodiment, the water spray moving device 5 further comprises a sealing sleeve 58 installed on the inner side of the valve body 53 , and the linkage insert 55 is inserted in the sealing sleeve 58 and cooperates with the sealing sleeve 58 in a dynamic seal.

[0031] The linkage insert 55 and the sealing sleeve 58 are a dynamic sealing set. When the linkage insert 55 is extended and retracted inside the sealing sleeve 58, its sealing performance will not be affected. Therefore, when the linkage insert 55 is moved and adjusted, water will not leak out.

[0032] In one embodiment, the water conduit 52 is composed of a one-way valve and a connecting pipe connected to each other, the other end of the connecting pipe is connected to the second water outlet of the diversion box 51, and the output end of the one-way valve is connected to the water spray pipe 57. The one-way valve is a normally open valve. When it is necessary to spray water to clean the double-helix agitator 1, water will flow from the water conduit 52 to the water spray pipe 57 and spray into the double-helix agitator 1.

[0033] In one embodiment, sealing rings are installed at the connection between the water pipe 52 and the valve body 53 and the water pipe 52. The sealing rings may be silicone rings, which seal the connection between the above components, thereby improving the sealing ability of the structure.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0036] In addition, "plurality" means two or more.
