Description

Technical Field

[0001] This utility model relates to the technical field of dewaxing and crystallization mixing tanks, and in particular to a dewaxing and crystallization mixing tank with uniform cooling. Background Technology

[0002] Dewaxing crystallization stirred tanks are key equipment in chemical, petroleum refining, and food processing industries for separating waxy components from mixtures. Their purpose is to promote wax crystal growth by controlling temperature and stirring conditions, causing waxy components to crystallize and precipitate from the liquid mixture, forming uniform micro-crystals. This creates favorable conditions for subsequent solid-liquid separation (such as filtration or centrifugation), improving wax-oil separation efficiency. By optimizing the crystallization process, as much wax as possible is precipitated in solid form, reducing wax residue in the liquid phase, thereby improving dewaxing efficiency and product quality. Improved product flowability: After wax removal, the viscosity of the remaining oil phase decreases, increasing flowability and facilitating subsequent processing or storage. Adaptability to different raw material characteristics: By adjusting operating parameters (such as temperature and stirring speed), the system can adapt to raw materials with different wax contents or compositions, ensuring process stability.

[0003] In the utility model patent with patent publication number CN221182434U, the oil to be separated is fed into the tank through the inlet. After the oil enters the tank, cold water is fed into the cooling coil through the water inlet. Then, the stirring device is started, which drives the sleeve to rotate. The rotation of the sleeve drives the uniform folding blade to rotate. When the uniform folding blade rotates, the cold water cools the oil in the tank through the cooling coil before flowing out from the water outlet. The end of the uniform folding blade is designed with a 120° bend, which makes it easy to move all the oil to be separated in the tank together during the stirring process. In particular, the oil around the cooling coil near the side wall of the tank is less likely to adhere to the cooling coil under this stirring action, achieving uniform cooling. After the temperature sensor detects that the temperature in the tank has reached the required level, the oil can be taken out through the outlet.

[0004] While the above solution can achieve uniform cooling of the oil, it also has drawbacks. Because the oil is at a high temperature when it enters the tank, a large amount of cooling water is needed to complete the cooling process during the initial heat exchange with the cooling water. This not only reduces the cooling efficiency but also increases the corresponding energy consumption, which is not conducive to practical use.

[0005] Therefore, it is necessary to provide a dewaxing and crystallization stirring tank with uniform cooling to solve the above-mentioned technical problems. Utility Model Content

[0006] In response to the above situation and to overcome the defects of the existing technology, this utility model provides a dewaxing and crystallization stirring tank with uniform cooling. This solves the problem that in the existing device, because the oil is at a high temperature when it enters the tank, a large amount of cooling water is required to complete the cooling operation when it initially contacts the cooling water for heat exchange. This not only reduces the cooling efficiency, but also increases the corresponding energy consumption, which is not conducive to practical use.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A uniformly cooled dewaxing and crystallization stirred tank includes: a stirred tank, a pretreatment box, and a pretreatment mechanism;

[0009] The pretreatment mechanism consists of a feed pipe, a feeding box, a diversion pipe, a discharge box, and a discharge pipe. The right end of the feed pipe is connected to the feeding box. Multiple diversion pipes are installed on the right end of the feeding box. The diversion pipes are arranged in a rectangular array. The other end of the diversion pipe is connected to the discharge box. The bottom of the discharge box is connected to the tank body through the discharge pipe. An electrically controlled valve is installed at the connection between the two.

[0010] In one embodiment, the pretreatment box has two open ends, which are respectively sealed to the feeding box and the discharging box. A collection box is installed at the bottom of the pretreatment box, and the bottom of the collection box is connected to the cooling pipe inside the tank through a collection pipe. An electrically controlled valve is installed at the connection. An agitator is installed inside the tank. The top of the pretreatment box has mounting ports in a rectangular array. The front end of the pretreatment box has a connection port, and multiple sets of connection ports are spaced apart vertically. The mounting ports and connection ports are respectively installed and connected to the liquid cooling mechanism and the air cooling mechanism. An exhaust port is opened on the top side of the rear end of the pretreatment box, and the exhaust port is arranged opposite to the air cooling mechanism.

[0011] In one embodiment, the liquid cooling mechanism consists of an inlet pipe, a drain pipe, and nozzles. The right end of the inlet pipe is connected to a drain pipe. Multiple sets of drain pipes are installed at intervals. Each set of drain pipes has nozzles installed at intervals at its bottom. The nozzles are located inside the installation port, and their number and orientation are consistent with the installation port. The nozzles are positioned directly below the gap between adjacent branch pipes.

[0012] In one embodiment, the air-cooling mechanism consists of an air outlet plate, a connecting pipe, a main air duct, a cooling box, and an air inlet pipe. The number and orientation of the air outlet plates are consistent with the connecting port. The air outlet plates are located inside the connecting port and the two are sealed together. The air outlet plates are connected to the main air duct through the connecting pipe. The front end of the main air duct is connected to the air inlet pipe through the cooling box. The other end of the air inlet pipe is installed and connected to an external fan.

[0013] In one embodiment, a top cover is attached to the top of the cooling box and snaps onto it, a perforated plate is installed in the middle of the cooling box, and a cooling material is placed on top of the perforated plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) This utility model introduces the oil to be processed into the feed box through the feed pipe, and the oil in the feed box is diverted through several rectangular array of diversion pipes. The oil is then transported through a miniaturized conveying pipe, which increases the contact area with the low-temperature air outside, increases the preheating efficiency, and thus improves the subsequent processing efficiency. Cooling water is sprayed towards the diversion pipe through the nozzle to preheat and cool the diversion pipe. The water will adhere to the diversion pipe and continue to flow into the collection box. After accumulating for a period of time, it is introduced into the cooling pipe inside the tank through the collection pipe. While preheating the diversion pipe, resources are also used reasonably, and the overall practicality of the device is improved.

[0016] (2) This utility model draws low-temperature air from the outside into the main air duct through an external fan, and blows air evenly onto the distribution pipe through multiple upper and lower air outlets to cool it down. By setting the fan parameters, the overall blowing is in a weak wind blowing mode. The purpose is to create a low-temperature zone in the pretreatment box, preventing strong winds from blowing the sprayed cooling water out of the pretreatment box's exhaust port. The low-temperature air can also cool the already cooled cooling water, improving the overall practicality of the device, enhancing the pretreatment effect, and simultaneously improving the cooling efficiency for subsequent oil. By placing cooling materials, such as ice blocks, crushed ice, or frozen ice packs, above the perforated plate, the air-cooled temperature is further reduced, further improving the pretreatment cooling effect.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0023] like Figures 1-2 As shown, the present invention provides a uniformly cooled dewaxing and crystallization stirring tank, comprising: a stirring tank 1, a pretreatment box 2, and a pretreatment mechanism 3;

[0024] like Figures 1-2 As shown, the pretreatment mechanism 3 consists of an inlet pipe 31, a feeding box 32, a diversion pipe 33, a discharge box 34, and a discharge pipe 35. The right end of the inlet pipe 31 is connected to the feeding box 32. Multiple diversion pipes 33 are installed on the right end of the feeding box 32. The diversion pipes 33 are arranged in a rectangular array. The other end of the diversion pipe 33 is connected to the discharge box 34. The bottom of the discharge box 34 is connected to the tank 1 through the discharge pipe 35. An electrically controlled valve is installed at the connection between the two. During operation, the oil to be processed enters the feeding box 32 from the inlet pipe 31. The oil in the feeding box 32 is diverted through several diversion pipes arranged in a rectangular array. The oil passes through a miniaturized conveying pipe, which increases the contact area with the low-temperature air outside, increases the preheating efficiency, and thus improves the subsequent processing efficiency.

[0025] Preferably, in one embodiment, such as Figures 2-3 As shown, both ends of the pretreatment box 2 are open, and both ends are sealed to the feeding box 32 and the discharging box 34 respectively. A collection box 21 is installed at the bottom of the pretreatment box 2. The bottom of the collection box 21 is connected to the cooling pipe inside the tank 1 through the collection pipe 22. An electric control valve is installed at the connection. An agitator is installed inside the tank 1. The top of the pretreatment box 2 has a rectangular array of installation ports 23. The front end of the pretreatment box 2 has a connection port 24. Multiple sets of connection ports 24 are spaced vertically. The installation ports 23 and connection ports 24 are respectively installed and connected to the liquid cooling mechanism 4 and the air cooling mechanism 5. An exhaust port is opened on the top side of the rear end of the pretreatment box 2. The exhaust port is opposite to the air cooling mechanism 5.

[0026] Preferably, in one embodiment, such as Figures 2-3As shown, the liquid cooling mechanism 4 consists of an inlet pipe 41, a drain pipe 42, and nozzles 43. The right end of the inlet pipe 41 is connected to the drain pipe 42. Multiple sets of drain pipes 42 are installed at intervals, and nozzles 43 are installed at intervals at the bottom of each set of drain pipes 42. The nozzles 43 are located inside the installation port 23, and their number and position are consistent with the installation port 23. The nozzles 43 are positioned directly below the gap between adjacent branch pipes 33. During operation, cooling water is sprayed towards the branch pipes 33 through the nozzles 43 to pre-treat and cool the branch pipes 33. The water adheres to the branch pipes 33 and continues to flow downwards into the collection tank 21. After accumulating for a period of time, it is guided through the collection pipe 22 into the cooling pipe body inside the tank 1. While pre-cooling the branch pipes 33, resources are also used rationally, improving the practicality of the overall device.

[0027] Preferably, in one embodiment, such as Figures 3-4 As shown, the air-cooling mechanism 5 consists of an air outlet plate 51, a connecting pipe 52, a main air duct 53, a cooling box 54, and an air inlet pipe 55. The number and orientation of the air outlet plates 51 are consistent with the connecting port 24. The air outlet plates 51 are located inside the connecting port 24, and the two are sealed together. The air outlet plates 51 are connected to the main air duct 53 through the connecting pipe 52. The front end of the main air duct 53 is connected to the air inlet pipe 55 through the cooling box 54. The other end of the air inlet pipe 55 is connected to an external fan. During operation, air is supplied through the connecting pipe 52. The external fan draws low-temperature outside air into the main air duct 53, and the multiple upper and lower air outlets 51 uniformly blow air onto the distribution pipe 33 to cool it down. By setting the fan parameters, the overall blowing is in a weak wind blowing mode. The purpose is to create a low-temperature zone inside the pretreatment box 2, preventing strong winds from blowing the sprayed cooling water out of the exhaust port of the pretreatment box 2. The low-temperature air can also cool the already cooled cooling water, improving the practicality of the overall device, improving the pretreatment effect, and simultaneously improving the cooling efficiency for subsequent oil.

[0028] Preferably, in one embodiment, such as Figure 4 As shown, the top of the cooling box 54 is fitted with a top cover 56 that is snapped together with it, and a perforated plate 57 is installed in the middle of the cooling box 57. Cooling materials, such as ice cubes, crushed ice, or frozen ice packs, are placed on top of the perforated plate 57. By placing cooling materials in the perforated plate 57, the temperature of the air cooling is further reduced, and the pretreatment cooling effect is further improved.

[0029] Working principle of this utility model:

[0030] During operation, the oil to be processed enters the feed tank 32 through the feed pipe 31. The oil in the feed tank 32 is then diverted through several rectangular arrayed diversion pipes 33. This miniaturized conveying system increases the contact area with the low-temperature ambient air, improving pre-cooling efficiency and consequently enhancing subsequent processing efficiency. Cooling water is sprayed from the nozzles 43 towards the diversion pipes 33 for pre-cooling. The water adheres to the diversion pipes 33 and continues downward into the collection tank 21. After accumulating for a period, it is guided through the collection pipe 22 into the cooling pipes inside the tank 1. While pre-cooling the distribution pipe 33, it also makes reasonable use of resources and improves the practicality of the overall device. The external fan draws low-temperature air into the main air pipe 53, and the distribution pipe 33 is cooled evenly by multiple upper and lower air outlets 51. By setting the fan parameters, the overall blowing is in a weak wind blowing mode. The purpose is to create a low-temperature zone in the pretreatment box 2, preventing strong winds from blowing the sprayed cooling water out of the exhaust port of the pretreatment box 2. The low-temperature air can also cool the already cooled cooling water, improving the practicality of the overall device, improving the pretreatment effect, and simultaneously improving the cooling efficiency for subsequent oil.

[0031] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
