Description

Technical Field

[0001] This invention relates to the field of rice bran oil production and processing technology, specifically to a deodorization tower for high acid value rice bran oil production. Background Technology

[0002] During the production of rice bran oil, it is necessary to remove odors and unpleasant smells to prevent them from affecting the quality of the oil. A plate deodorizing tower is used for this purpose. The plate deodorizing tower utilizes the fact that small-molecule odorous organic compounds in the oil 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, thus achieving the purpose of odor removal. It is one of the commonly used equipment in rice bran oil processing.

[0003] In existing plate-type deodorization towers, the diversion plates are typically fixed directly inside the tower. If these plates become damaged or clogged after prolonged use, requiring cleaning or replacement, they must be disassembled. The current fixed structure makes this disassembly cumbersome, impacting the plate's usability. Furthermore, the steam nozzles inside existing deodorization towers, used for spraying high-temperature steam, are usually fixed to the frame. When one nozzle fails and needs replacement, the entire frame and all the nozzles on it must be replaced, resulting in resource waste. Summary of the Invention

[0004] To address the problems of existing technologies, this invention provides a deodorization tower for high acid value rice bran oil production, comprising a tower body, an oil inlet located on the upper side of one side of the tower body, an oil inlet pipe provided at the oil inlet, and a flow divider plate located inside the tower body below the oil inlet. Two C-shaped fixing frames are symmetrically arranged on the inner wall of the tower body, and the flow divider plate is positioned between the two fixing frames. The flow divider plate has several vertically penetrating holes. Both ends of the flow divider plate are detachably and fixedly connected with Velcro fasteners, the other side of which is adhered to one side of the fixing plate. A slider is fixedly connected to the bottom of each of the two fixing plates, and a slide rail is fixedly installed inside each of the two fixing frames, allowing the slider to slide on the corresponding slide rail. Below the diversion plate are several steam nozzles for ejecting steam. Each steam nozzle is detachably and fixedly connected to the support block via a disassembly structure. The top of the support block has a limiting groove, and both sides of the inside of the support block have empty grooves that communicate with the limiting groove. The disassembly mechanism includes a first limiting block, a positioning block, a movable plate, and springs. The first limiting block is fixed to the bottom of the steam nozzle. The number of positioning blocks is set to two and they are respectively located in the limiting groove. The number of movable plates is set to two and they are respectively located in the two empty grooves. The number of springs is set to two and they are respectively fixed between the outer end of the movable plate and the inner wall of the empty groove.

[0005] A further option is to provide a baffle at the other end of both of the fixing frames.

[0006] A further option is to fix a handle to one end of the fixing plate.

[0007] A further option is to have a closed door on the front outer wall surface of the tower body, with the position of the closed door corresponding to the position of the handle.

[0008] A further embodiment is that the first limiting block has positioning grooves on both the left and right sides, and fixing rods are provided at both the upper and lower ends of the empty groove. The upper and lower sides of the movable plate are respectively sleeved on the outside of the fixing rods and slidably connected to them. The upper end of the movable plate extends through the support block, and the inner end of the movable plate extends through the empty groove and is fixed to the outer end of the positioning block. The first limiting block is inserted into the limiting groove, and the positioning block is inserted into the positioning groove.

[0009] A further option is to fix all the support blocks on the mounting plate, and the two ends of the mounting plate are respectively fixedly connected to the inner wall of the tower body through brackets.

[0010] A further embodiment is that the outer wall of the tower body is circumferentially fitted onto a support ring, and a number of support legs are fixedly connected to the bottom of the support ring. Each support leg has a shock-absorbing mechanism movably installed at its bottom. The shock-absorbing mechanism includes a housing, and a shock-absorbing spring is movably fitted inside the housing. A second limiting block is fixedly installed on the lower outer surface of the shock-absorbing spring, and a piston is movably installed on the upper outer surface of the shock-absorbing spring. A sponge block is fixedly installed on the lower outer surface of the piston near both sides. The piston is connected to the support leg, and a foot is fixedly installed on the lower outer surface of the second limiting block.

[0011] A further embodiment is that several of the support legs are arranged in a ring at the bottom of the support ring. Beneficial effects of the present invention

[0012] This invention enables the rapid disassembly and assembly of the diverter plate by using a combination of a fixed frame, hook and loop fastener, a fixed plate, a slider, and a slide rail.

[0013] The present invention features several steam nozzles that are detachably and fixedly connected to their corresponding support blocks via a disassembly structure. This allows for the individual removal and replacement of a damaged steam nozzle, avoiding the need to replace the entire steam nozzle and mounting frame when a single steam nozzle is damaged, as is the case in existing technologies. Furthermore, the removal and installation of the steam nozzles are simple and quick. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0016] like Figures 1-4 As shown, one embodiment of the present invention discloses a deodorization tower for high acid value rice bran oil production, including a tower body 1. An oil inlet is located on the upper side of one side of the tower body 1, and an oil inlet pipe 10 is installed at the oil inlet. A flow divider 2 is installed inside the tower body 1, positioned below the oil inlet. Several steam nozzles 4 for ejecting steam are located below the flow divider 2, and all steam nozzles 4 are connected to an external steam generator via gas transmission pipes. An oil outlet is located at the bottom of the tower body 1, and an oil outlet pipe 11 is connected to the oil outlet.

[0017] This embodiment, through the above-described setup, firstly generates a large amount of steam via an external steam generator, which is then transported through pipelines to the interior of the tower and ejected through several steam nozzles. Next, the rice bran oil to be deodorized is injected into the deodorization tower through the inlet pipe and falls onto a distribution plate for diversion. The diverted rice bran oil comes into contact with the high-temperature steam. When water vapor passes through the odor-containing rice bran oil, it becomes saturated with the volatile odor components and escapes according to their partial pressure ratio, thus achieving the effect of deodorizing the rice bran oil. The deodorized rice bran oil can be discharged through the outlet pipe at the bottom of the tower.

[0018] The inner wall of the tower body 1 is symmetrically provided with two "C"-shaped fixing frames 30. The diversion plate 2 is located between the two fixing frames 30. The diversion plate 2 has several vertical diversion holes 20 that penetrate the diversion plate 2. Both ends of the diversion plate 2 can be detachably and fixedly connected with hook and loop fasteners 31. The other side of the hook and loop fasteners 31 is attached to one side of the fixing plate 32. The bottom of both fixing plates 32 is fixedly connected with sliders 33. The interior of both fixing frames 30 is fixedly provided with slide rails 34. The sliders 33 can slide on the slide rails 34 on the corresponding side. The front outer wall surface of the tower body 1 is provided with a closed door, and the position of the closed door corresponds to the position of the handle 36.

[0019] This embodiment, through the above-described configuration, allows for the manual opening of the tower's sealed door when the diverter plate needs cleaning or replacement after prolonged use. The two ends of the connection between the diverter plate and the fixed plate are then slid outwards along the slide rails on the corresponding sides of the fixed frame using sliders. After sliding out, the Velcro fasteners are released, the diverter plate is removed, and it is cleaned or replaced directly with a new diverter plate. The Velcro fasteners are then fastened, and the new diverter plate is connected to the fixed plate. The two ends of the connection between the new diverter plate and the fixed plate are then slid along the slide rails on the corresponding sides of the fixed frame using sliders to complete the installation. This allows for quick disassembly and assembly of the diverter plate, facilitating cleaning or replacement.

[0020] In this embodiment, baffles 35 are provided at the other end of both fixing brackets 30.

[0021] This embodiment, through the above-described configuration, can prevent the entire connection between the fixing plate and the diverter plate from sliding in from one end of the fixing frame and then out from the other end.

[0022] In this embodiment, a handle 36 is fixedly connected to one end surface of the fixing plate 32.

[0023] In this embodiment, the handles allow for smoother pulling or pushing of both ends of the connection between the fixing plate and the diverter plate into the corresponding fixing frame.

[0024] Several steam nozzles 4 are detachably and fixedly connected to the support block 5 through a disassembly structure. The top of the support block 5 is provided with a limiting groove 50, and both sides of the inside of the support block 5 are provided with empty grooves 51 that communicate with the limiting groove 50. The disassembly mechanism includes a first limiting block 52, a positioning block 53, a movable plate 54, and a spring 55. The first limiting block 52 is fixed to the bottom of the steam nozzle 4. The number of positioning blocks 53 is set to two and they are respectively set in the limiting groove 50. The number of movable plates 54 is set to two and they are respectively set in two empty grooves 51. The number of springs 55 is set to two and they are respectively fixed between the outer end of the movable plate 54 and the inner wall of the empty groove 51.

[0025] In this embodiment, the first limiting block 52 has positioning grooves 56 on both the left and right sides, and the upper and lower ends of the empty groove 51 have fixing rods 57. The upper and lower sides of the movable plate 54 are respectively sleeved on the outside of the fixing rods 57 and slidably connected to them. The upper end of the movable plate 54 passes through the support block 5, and the inner end of the movable plate 54 passes through the empty groove 51 and is fixed to the outer end of the positioning block 53. The first limiting block 52 is inserted into the limiting groove 50, and the positioning block 53 is inserted into the positioning groove 56.

[0026] This embodiment, through the above-described configuration, enables the following steps when a steam nozzle is damaged and needs replacement: First, the movable plate corresponding to the steam nozzle is moved outward, causing the movable plate to slide outside the fixed rod. During the movement of the movable plate, a spring is also compressed, simultaneously causing the positioning block to move outward and disengage from the positioning groove. After the positioning block disengages from the positioning groove, it enters the empty groove. Then, the steam nozzle can be moved upward, causing the flushing nozzle to pull the first limiting block out of the limiting groove, thereby removing the steam nozzle. The above method of disassembling the steam nozzle is quick and convenient.

[0027] When a new steam nozzle needs to be installed, the steam nozzle is moved to insert the first limiting block into the limiting groove, so that the limiting groove and the empty groove correspond to each other. Then, the movable plate is released, and the spring rebounds, causing the spring to move the movable plate and the positioning block inward, thereby moving the positioning block out of the empty groove and into the positioning groove. Therefore, the positioning block is used to position the first limiting block and the steam nozzle, thereby ensuring the stability of the steam nozzle installation. The above method of installing steam nozzles is convenient, quick and stable.

[0028] This embodiment allows for the detachable and fixed connection of all steam nozzles to their corresponding support blocks, enabling the replacement of individual damaged steam nozzles. This avoids the need to replace the entire steam nozzle and mounting frame when a single steam nozzle is damaged, as is the case in existing technologies. Furthermore, the disassembly and installation of the steam nozzles are simple and quick.

[0029] In this embodiment, all support blocks 5 are fixedly mounted on the mounting plate 6, and both ends of the mounting plate 6 are fixedly connected to the inner wall of the tower body 1 through brackets 7.

[0030] This embodiment allows for convenient installation and fixation of all steam nozzles through the above-described settings.

[0031] In this embodiment, the outer wall of the tower body 1 is circumferentially fitted onto the support ring 80. Several support legs 81 are fixedly connected to the bottom of the support ring 80. A shock-absorbing mechanism is movably installed at the bottom of each support leg 81. The shock-absorbing mechanism includes a housing 82. A shock-absorbing spring 83 is movably fitted inside the housing 82. A second limiting block 84 is fixedly installed on the lower outer surface of the shock-absorbing spring 83. A piston 85 is movably installed on the upper outer surface of the shock-absorbing spring 83. A sponge block 86 is fixedly installed on the lower outer surface of the piston 85 near both sides. The piston 85 is connected to the support leg 81. A support foot 87 is fixedly installed on the lower outer surface of the second limiting block 84.

[0032] This embodiment, through the above-described configuration, enables the deodorization tower to vibrate under external impact. The impact force is transmitted from the deodorization tower to the support ring, then to each support leg, and finally to the shock-absorbing mechanism. The piston, acting on the impact force, moves downwards, causing it to press against the shock-absorbing elastic element, which then buffers some of the impact energy. A limiting block restricts the movement of the shock-absorbing elastic element, and the piston's movement also compresses the sponge block, further absorbing the impact force. This minimizes the vibration impact and prevents excessive impact from affecting the stability of the deodorization tower.

[0033] In this embodiment, several support legs 81 are arranged in a ring at the bottom of the support ring 80.

[0034] In this embodiment, the support legs distributed as described above can provide stable support for the support ring and the deodorization tower.

[0035] Finally, it should be noted that the above description is only for specific embodiments of the present invention. However, the present invention is not limited to the specific embodiments described above. Equivalent modifications and substitutions made to the present invention by those skilled in the art are also within the scope of the present invention. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of the present invention are covered within the scope of the present invention.
