Description

Technical Field

[0001] This utility model belongs to the field of vegetable oil technology, specifically relating to a vegetable oil deodorization tower. Background Technology

[0002] The deodorization tower for vegetable oils utilizes the fact that small-molecule odorous organic compounds in oils are more volatile than triglycerides under high temperature and negative pressure. When water vapor passes through the odorous oil, it is saturated with the volatile odor components and escapes according to their partial pressure ratio, thereby achieving the purpose of deodorization.

[0003] In existing deodorization processes, such as the deodorization tower for vegetable oil disclosed in application number CN201620494808.4, only the steam deodorization structure of the deodorization tower is proposed, without any improvement to the pre-deodorization work. While the vegetable oil deodorization tower proposed in application number CN202321393791.X mentions adding a filtration device to the tower body, it only achieves high-efficiency filtration by adding a cleaning structure to the filter plates. This is clearly limited in practical use. For example, with a fixed filtration area, the filtration effect will inevitably decrease as the filtered impurities accumulate, even leading to blockage and a gradual decrease in flow velocity. Furthermore, although brushes are installed, it is still difficult to clean impurities inside the tower, affecting the filtration effect and causing inconvenience in the deodorization process.

[0004] In summary, the technical problems existing in the above-mentioned prior art need to be solved in order to reduce the deodorization process of vegetable oil and improve the convenience of vegetable oil deodorization work. Utility Model Content

[0005] The purpose of this invention is to provide a vegetable oil deodorization tower to solve the problems of difficulty in ensuring filtration effect and inconvenience in cleaning accumulated impurities.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vegetable oil deodorization tower, comprising a tower body, a pretreatment section fixedly installed on the top wall of the tower body, a feed inlet provided on the upper outer wall of the tower body, the pretreatment section being fixedly connected to the feed inlet, the pretreatment section comprising a treatment box and a filter plate, the treatment box being fixedly installed on the upper outer wall of the tower body, and the filter plate being fixedly installed inside the treatment box.

[0007] Preferably, the filter plate is a hollow truncated quadrangular shape with an upward convex shape. A fixing plate is provided on the outer wall of the lower side of the filter plate. The fixing plate is fixedly connected to the inner wall of the processing box. A guide plate is fixedly connected to the side of the filter plate near the fixing plate. A material trough is provided between the guide plate and the fixing plate.

[0008] Preferably, the fixing plate is provided with a curved groove located on the outside of the filter plate, and the fixing plate is provided with a collection groove located on one side of the material trough, and the collection groove is provided with filter holes.

[0009] Preferably, the outer wall of the lower side of the processing box is provided with an opening, and a base plate is fixedly installed at the opening. The base plate is provided with a downwardly protruding quadrangular frustum.

[0010] Preferably, a discharge port is provided at the center of the bottom plate, and the discharge port is fixedly connected to the inlet.

[0011] Preferably, the outer wall of the upper side of the processing box is provided with a top plate, the top plate is provided with a feed pipe, and the feed pipe is provided with a flow valve.

[0012] Preferably, a support base is provided on the outer wall of the lower side of the tower body, and the support base is fixedly installed on the outer wall of the lower side of the tower body. An inspection port is provided on the tower body.

[0013] The technical effects and advantages of this utility model are as follows: The pretreatment section set on the upper side of the tower body allows vegetable oil to first contact the top of the filter plate after entering the treatment tank. With the flow rate and the force generated by the contact between the filter plate and the oil, the oil is splashed outwards, thus comprehensively filtering the vegetable oil. Impurities will gradually disperse outwards, and with continuous impact and accumulation of impurities, they will be flushed into the material trough through the curved channel and finally fall into the collection tank. By increasing the filtration area and collecting impurities uniformly, the filtration efficiency is improved, which facilitates subsequent deodorization work. By setting up the pretreatment section, the deodorization work is facilitated, the operation steps are reduced, and the production cost is reduced. Attached Figure Description

[0019] 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.

[0020] This utility model provides, for example Figure 1-4 The vegetable oil deodorization tower shown includes a tower body 1. A pretreatment section 2 is fixedly installed on the top wall of the tower body 1. A feed inlet 3 is provided on the upper outer wall of the tower body 1. The pretreatment section 2 is fixedly connected to the feed inlet 3. The pretreatment section 2 includes a treatment box 4 and a filter plate 5. The treatment box 4 is fixedly installed on the upper outer wall of the tower body 1, and the filter plate 5 is fixedly installed inside the treatment box 4. A support base 17 is provided on the lower outer wall of the tower body 1. The support base 17 is fixedly installed on the lower outer wall of the tower body 1. An inspection port 18 is provided on the tower body 1.

[0021] A pretreatment section 2 is provided on the upper side of the tower body 1. During use, vegetable oil is fed into the treatment tank 4 through the feed pipe 15. Inside the treatment tank 4, a filter plate 5 is installed to filter impurities from the vegetable oil. The filter plate 5 is fixedly installed on the inner wall of the treatment tank 4 by a fixing plate 6, and the filter plate 5 is in the shape of an upwardly extending truncated pyramid. After the vegetable oil enters the treatment tank 4, it first contacts the top of the filter plate 5, and then, due to the flow rate and the force generated by the contact with the filter plate 5, it splashes outwards, thus thoroughly filtering the vegetable oil. Furthermore, the impurities in the vegetable oil are filtered out... Impurities will remain on filter plate 5. As the vegetable oil continuously comes into contact with filter plate 5, the impurities will gradually disperse to the surroundings until they impact one side of fixed plate 6 through guide plate. With continuous impact and accumulation of impurities, the impurities will be flushed into material tank 8 through curved groove 9 and finally fall into collection tank 10. The curved groove 9 and material tank 8 are designed to reduce the accumulation of impurities in the filtration of large amounts of vegetable oil, which is not conducive to the subsequent filtration of vegetable oil, thus improving filtration efficiency and facilitating the subsequent deodorization of vegetable oil.

[0022] Specifically, the filter plate 5 is a hollow, upward-convex truncated quadrangular truncated pyramid. A fixing plate 6 is provided on the lower outer wall of the filter plate 5, and the fixing plate 6 is fixedly connected to the inner wall of the processing box 4. A guide plate 7 is fixedly connected to the side of the filter plate 5 near the fixing plate 6, and a material trough 8 is formed between the guide plate 7 and the fixing plate 6. A curved groove 9 is provided on the fixing plate 6, located on the outer side of the filter plate 5. A collection trough 10 is provided on the fixing plate 6, located on one side of the material trough 8, and filter holes are provided on the collection trough 10. (See attached diagram.) Figure 2As shown, the outer wall of the lower side of the treatment box 4 is provided with an inwardly extending bottom wall. A fixing plate 6 is fixedly installed on the bottom wall. The fixing plate 6 is a U-shaped base. The filter plate 5 is fixedly installed on its upper side. The lower side is a rectangular opening. The fixing plate 6 is provided with a curved groove 9 around the outer side of the filter plate 5. A guide plate 7 is provided on the filter plate 5. After the vegetable oil enters the treatment box 4 and comes into contact with the filter plate 5, part of the vegetable oil is filtered from the top of the filter plate 5, and part is filtered by the side wall of the dispersed filter plate 5. The filter plate 5 is provided with a truncated quadrangular shape to increase the filtration area with the vegetable oil.

[0023] Furthermore, please refer to the appendix. Figure 3 As shown, the filtered impurities are dispersed under the force of the vegetable oil and, following the flow direction of the vegetable oil and the action of the guide plate 7, are impacted into the curved groove 9. After continuous impact, they enter the collection tank 10 from the material tank 8. The collection tank 10 is fixed to the lower side of the filter plate 5 and is provided with filter holes. When vegetable oil mixed with impurities enters the collection tank 10, the vegetable oil can be filtered out, leaving only the impurities. After processing a certain amount of vegetable oil or after the processing box 4 has been used for a certain period of time, the top plate 14 and / or the bottom plate 12 can be disassembled to clean the collection tank 10 and the filter plate 5, so as to ensure the filtration effect and filtration speed and ensure use.

[0024] Specifically, the lower outer wall of the processing box 4 has an opening 11, and a base plate 12 is fixedly installed at the opening 11. The base plate 12 has a downwardly protruding truncated quadrangular shape. An outlet 13 is located at the center of the base plate 12, and the outlet 13 is fixedly connected to the inlet 3. The upper outer wall of the processing box 4 has a top plate 14, on which an inlet pipe 15 is installed, and a flow valve 16 is installed on the inlet pipe 15. (See attached diagram.) Figure 3 , 4As shown, opening 11 is located at the center of the bottom wall of the processing box 4. A base plate 12 is installed at opening 11. The protrusion direction of the base plate 12 is opposite to that of the truncated pyramid of the filter plate 5. The collection trough 10 is located inside the fixing plate 6 and is a symmetrically arranged hollow groove. After the vegetable oil comes into direct contact with the top or side wall of the filter plate 5, it will fall directly into the base plate 12 through the hollow part of the collection trough 10 and flow out of the processing box 4 through the outlet 13. If the vegetable oil is impacted by the guide plate and flows to the material trough 8, it will fall into the collection trough 10. After being filtered by the collection trough 10, it falls into the base plate 12. 2. The oil flows out through outlet 13 and enters tower body 1 through outlet 13 for deodorization. By adding a pretreatment section 2 to tower body 1, the deodorization of vegetable oil is facilitated, reducing operating procedures and production costs, which is beneficial to the development of the factory. In order to ensure the efficient operation of deodorization, a check valve is installed on outlet 13 to block the liquid flow between pretreatment section 2 and tower body 1 during deodorization. A steam distillation structure for vegetable oil deodorization is installed in tower body 1. Pretreatment section 2 works in conjunction with tower body 1 to facilitate efficient deodorization of vegetable oil.

[0025] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
