Description
Technical Field
[0001] The utility model relates to the technical field of dewaxing, in particular to a lacquer seed kernel dewaxing device for producing lacquer seed oil. Background Art
[0002] Lacquer seed is the fruit of the lacquer tree, which is flat and obliquely spherical, with a high oil content. Lacquer wax and lacquer seed oil can be extracted from the lacquer seed skin and lacquer seed kernel, respectively. The lacquer seed peel is divided into three layers, the exocarp is membranous, fish belly white, grayish yellow or yellow-green, the mesocarp is a waxy layer, which is light yellow or grayish green, from which lacquer wax can be extracted, and the kernel is a seed, with a crude fat content of 45-55%, from which lacquer seed oil can be extracted. There has always been a habit of processing lacquer seeds in the lacquer tree producing areas of my country, but when the lacquer seed kernel is processed by boiling or machine pressing, the original process often does not separate from the waxy layer of the lacquer seed kernel, and due to the presence of the waxy layer on the surface of the lacquer seed kernel, only lacquer wax oil (a mixture of lacquer wax and lacquer seed oil) can be obtained, and the lacquer wax needs to be separated from the lacquer seed oil by temperature-variable crystallization and filter aids. However, variable temperature crystallization often requires complex operations and steps such as heating, heat preservation, and cooling, which is time-consuming and energy-intensive, and easily leads to a high wax content in lacquer seed oil, a slow progress in the refining of lacquer seed oil, and low production efficiency. Therefore, it is urgent to provide a lacquer seed kernel dewaxing device that can pre-treat lacquer seed kernels, reduce the lacquer wax content in the extracted lacquer seed oil, reduce the load of lacquer seed oil refining and purification, and improve production efficiency and reduce production costs.

When the dewaxing device of the utility model is used for dewaxing or lacquer seed oil preparation, the efficiency is high, the cost is low, the oil and wax are fully separated, the wax content in the finished lacquer seed oil is less than 2%, and the energy consumption of the crystal growing dewaxing operation is saved.

DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the utility model.
[0023] Example 1
[0024] like Figure 1 The lacquer seed dewaxing device for lacquer seed oil production comprises: a tank body 1, a feed inlet 11, a liquid inlet 12 and an alkali inlet 13 are respectively arranged on the top of the tank body 1, and a spray port 14 is also arranged on the upper side wall of the tank body 1, and the spray port 14 is communicated with a multi-circle spray pipe 141 arranged inside the tank body 1, and water outlets are evenly distributed on the lower tube wall of the spray pipe 141; a motor 15 is arranged at the center position of the top of the tank body 1, and the output end of the motor 15 is connected to the fixed end of the cylinder 16, and the output end of the cylinder 16 is rotatably connected to the top of the tank body 1, and extends to the inside of the tank body 1 and is rotatably connected to the filter plate 17; an annular upper limit ring 171 and a lower limit ring 171 are arranged on the lower side wall of the tank body 1. The filter plate 17 is arranged between the upper limit ring 171 and the lower limit ring 172, and the filter plate 17 is slidably connected to the tank body 1; the lower limit ring 172 is arranged at the bottom of the tank body 1; a liquid outlet 18 is arranged at the bottom center of the tank body 1; a discharge port 19 is opened on the side wall of the tank body 1 above the lower limit ring 172 (preferably, when the filter plate 17 is placed on the lower limit ring 172, the discharge port 19 is best located on the upper surface of the filter plate 17, so as to facilitate the discharge of the lacquer kernels after dewaxing); a plurality of kneading rods 161 are provided on the lower side wall of the output end of the cylinder 16, and a plurality of movable stirring components 162 are staggered on the kneading rods 161.
[0025] The dewaxing device is used to pre-treat the lacquer seed kernels, and the main purpose is to remove the wax layer and wax layer residue on the surface of the lacquer seed kernels. In the dewaxing pre-treatment process, two stages of hot water soaking and alkaline water soaking are required. First, the lacquer seeds are fed into the tank body 1 through the feed port 11, and then hot water is fed through the liquid inlet 12 for soaking. After the soaking is completed, the cylinder 16 drives the filter plate 17 and the lacquer seed kernels thereon to move up, and the hot water soaking liquid is discharged from the liquid outlet 18. Then the cylinder 16 drives the filter plate 17 to move down, and then alkaline water is fed into it through the alkali inlet 13. After the alkaline water soaking is completed, the alkaline water soaking liquid with wax dissolved is discharged from the liquid outlet 18. Then the cylinder 16 drives the filter plate 17 and the lacquer seed kernels thereon to move up, and clean water is sprayed through the multi-circle spray pipe 141 to rinse the lacquer seed kernels. The spray coverage of the multi-circle spray pipe 141 is wider, and the flushing effect is better. After the flushing water is discharged, the filter plate 17 moves down to the discharge port 19, and the dewaxed lacquer seed kernels are discharged from the discharge port 19 and sent to the subsequent oil making device. The dewaxing pretreatment of the dewaxing device can remove the wax layer on the surface of the lacquer seed kernels, reduce the lacquer wax content in the lacquer seed oil, simplify the refining and purification process, reduce time and energy consumption, improve production efficiency and reduce production costs.
[0026] During the soaking and rinsing stages of the lacquer seed kernels, the motor 15 can be started, and the kneading rod 161 rotates with the motor 15 and the cylinder 16 inside the tank body 1, so as to achieve the stirring and kneading of the lacquer seed kernels. The movable stirring assembly 162 on the kneading rod 161 can increase the kneading range, thereby accelerating the damage and dissolution removal of the wax layer on the surface of the lacquer seed kernels, improving the dewaxing effect and dewaxing efficiency, and the process is safe and reliable. The motor 15 can be a single rotation direction, or a motor 15 that can achieve forward and reverse rotation, and can achieve rotational drive, which is not specifically limited here. The lacquer seed kernels are collected above the filter plate 17, and the lower limit ring 172 is arranged at the bottom of the tank body 1, which can make the gap between the filter plate 17 and the bottom of the tank body 1 smaller, and hot water or alkaline water can be used as much as possible to soak the lacquer seed kernels, and the use of hot water or alkaline water can also be reduced during the soaking process.
[0027] Example 2
[0028] Based on the above embodiments, Figure 2 In this embodiment, the filter plate 17 is a structure that is inclined downward from the center to the surroundings. A cavity of a certain volume is formed between the inclined filter plate 17 and the bottom of the tank body 1. When the liquid outlet 18 is opened to discharge liquid, the soaking liquid and the flushing liquid separated from the lacquer seed kernel can be temporarily stored in the cavity, which is convenient for subsequent rapid discharge, and also more convenient for the discharge of the lacquer seed kernel after dewaxing.
[0029] Preferably, a pusher blade 163 is further provided at the bottom of the output end of the cylinder 16, the lower surface of the pusher blade 163 abuts against the upper surface of the filter plate 17, and the side surface of the pusher blade 163 abuts against the inner wall of the tank body 1. When the pusher blade 163 rotates, it can push the lacquer seed kernel from a position away from the discharge port 19 to the vicinity of the discharge port 19, and at the same time, it can exert a centrifugal effect on the lacquer seed kernel so that it can be discharged from the discharge port 19, thereby accelerating the discharge of the lacquer seed kernel after dewaxing.
[0030] Example 3
[0031] Based on the above embodiments, Figure 3 In this embodiment, the movable stirring assembly 162 includes a connecting rod 164 and a stirring rod 165, and the kneading rod 161 is a hollow structure; one end of the connecting rod 164 is vertically fixed to the stirring rod 165; the other end of the connecting rod 164 extends to the inside of the kneading rod 161, and is rotatably connected to the inner wall of the kneading rod 161 on the side away from the stirring rod 165.
[0032] When the kneading rod 161 rotates, the connecting rod 164 and the stirring rod 165 in the movable stirring assembly 162 are driven to rotate. The stirring rod 165 is subjected to the resistance of the soaking liquid and the lacquer seed kernel, and the connecting rod 164 connected to the stirring rod 165 is rotatably connected to the kneading rod 161. Therefore, while the stirring rod 165 rotates with the kneading rod 161, it also rotates, changing the relatively fixed movement route of the lacquer seed kernel driven by the kneading rod 161, improving the comprehensiveness and uniformity of the stirring of the lacquer seed kernel, and also increasing the area of effective collision with the lacquer seed kernel, so as to improve the collision rate and dewaxing speed of the lacquer seed kernel during the movement. The kneading rod 161 and the connecting rod 164 are sealed with a common rotating shaft sealing ring, or other conventional rotating sealing methods in the field can also be used.
[0033] Example 4
[0034] Based on the above embodiments, Figure 3 In this embodiment, a plurality of elliptical spring pieces 166 are evenly distributed along the axial direction on the outer periphery of the stirring rod 165, a notch is provided in the middle of the long side of the elliptical spring piece 166, and the elliptical spring piece 166 on one side of the notch is screwed to the stirring rod 165 by a screw 167. The elliptical spring piece 166 is also for enhancing the stirring and friction effect of the movable stirring assembly 162, and the notch design can increase the elastic deformation of the elliptical spring piece 166, ensuring that the lacquer seed kernel is fully kneaded while preventing the lacquer seed kernel from being damaged by excessive squeezing force, thereby optimizing the dewaxing process.
[0035] like Figure 2Preferably, a plurality of elastic protrusions 168 are provided on the inner wall of the tank body 1 above the upper limit ring 171. The elastic protrusions 168 on the inner wall of the tank body 1 are made of rubber material, which is conducive to protecting the integrity of the lacquer seed kernels and avoiding excessive impact on the lacquer seed kernels. The elastic protrusions 168 can further increase the impact probability and kneading efficiency of the lacquer seed kernels, so that the wax on the surface of the lacquer seed kernels can be dissolved into the soaking liquid faster and more fully.
[0036] Example 5
[0037] On the basis of the above embodiment, in this embodiment, the dewaxing effect of the lacquer seed kernel is better when it is dewaxed at a higher temperature. Therefore, a heating mechanism (not shown in the drawings) is provided on the side wall of the tank body 1. The above heating mechanism can be a heating wire or other commonly used heating tubes in the art, and is not particularly limited here. The heating mechanism can heat or keep warm the soaking liquid in the tank body 1, which is conducive to improving the dewaxing effect.
[0038] like Figure 2 Preferably, a controller 10 is further provided on the top of the tank body 1, and the controller 10 is electrically connected to the motor 15 and the cylinder 16. The motor 15 and the cylinder 16 have a stage of working together and a stage of working separately during operation. The start and stop control of the motor 15 and the cylinder 16 by the controller 10 can improve the degree of mechanization and automation, and is also conducive to improving production efficiency.
[0039] The lacquer seed kernel dewaxing device for producing lacquer seed oil provided by the utility model, when working, firstly, lacquer seeds are fed into the tank body 1 through the feed inlet 11, and then hot water is fed into the tank body 1 through the liquid inlet 12, until the hot water submerges the lacquer seed kernels, then the water feeding is stopped, and the lacquer seed kernels are soaked in hot water. The motor 15 is started by the controller 10. The motor 15 rotates to drive the kneading rod 161 on the cylinder 16 to rotate inside the tank body 1. When the kneading rod 161 rotates, the connecting rod 164 and the stirring rod 165 in the movable stirring assembly 162 are driven to rotate. Therefore, the kneading rod 161 and the stirring rod 165 rotate around the circumference of the tank body 1. At the same time, the stirring rod 165 itself is also rotating. At the same time, the elliptical spring piece 166 on the stirring rod 165 also stirs and rubs the lacquer seed kernel. Driven by the kneading rod 161 and the stirring rod 165, the lacquer seed kernel moves in an uncertain direction in the hot water, and also hits the elastic protrusion 168 on the inner wall of the tank body 1, thereby improving the impact rate and dewaxing speed of the lacquer seed kernel during the movement from many aspects.
[0040] After soaking in hot water for a period of time (the technicians in this field can choose the soaking time by themselves), start the cylinder 16, and the cylinder 16 drives the filter plate 17 and the lacquer seed kernels thereon to move up. When the filter plate 17 moves up to below the upper limit ring 171, the contraction of the cylinder 16 ends. At this time, the motor 15 may rotate or not. Rotation increases the friction between the lacquer seed kernels and the lacquer seed kernels, which helps to speed up dewaxing. Open the liquid outlet 18, and the hot water soaking liquid is discharged from the liquid outlet 18. Then when the cylinder 16 drives the filter plate 17 to move down to above the lower limit ring 172, the extension of the cylinder 16 ends, and then alkaline water is sent into it through the alkali inlet 13. The working process of alkaline water soaking is the same as that of hot water soaking, which will not be repeated here. During the hot water soaking and alkaline water soaking, the heating mechanism on the side wall of the tank body 1 can also be turned on to heat or keep the soaking liquid in the tank body 1 warm, which is conducive to improving the dewaxing effect.
[0041] After the alkaline water soaking is completed, the alkaline water soaking liquid with dissolved wax is discharged from the liquid outlet 18. Then the cylinder 16 drives the filter plate 17 and the lacquer seed kernels thereon to move upward, opens the spray port 14, and sprays clean water through the water outlet on the spray pipe 141 to rinse the lacquer seed kernels on the filter plate 17. During the rinsing, the kneading rod 161 and the stirring rod 165 are still rotated to facilitate the removal of the wax on the surface of the lacquer seed kernels. The flushing water does not stay in the tank body 1 and is directly discharged from the liquid outlet 18. After the rinsing is completed, the filter plate 17 moves down to the discharge port 19, and the lacquer seed kernels are pushed from a position away from the discharge port 19 to the vicinity of the discharge port 19 by the push blade 163, and the dewaxed lacquer seed kernels are discharged from the device from the discharge port, and the controller 10 controls the motor 15 and the cylinder 16 to cut off the power, and the dewaxing pretreatment of the lacquer seed kernels is completed.
[0042] It should be noted that in the present invention, the detailed structure of some devices is not described in detail, but belongs to the prior art known to those skilled in the art, so it will not be repeated here. In addition, the parts not involved in the device are the same as the prior art or can be implemented by using the prior art.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it; although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to replace some or all of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
