Description

Technical Field

[0001] This utility model relates to the field of rapeseed oil production technology, specifically to a washing device for rapeseed oil production. Background Technology

[0002] Rapeseed oil is a vegetable oil extracted from rapeseed and widely used in cooking and food processing. It primarily comes from rapeseed seeds. Processing methods include pressing and solvent extraction. Physical pressing retains more nutrients and produces a richer aroma, but the oil yield is lower. Solvent extraction is more efficient but may leave trace amounts of solvent residue. In rapeseed oil production, washing is a pretreatment step. During harvesting and storage, rapeseed may be mixed with soil, straw fragments, etc. Washing helps to initially remove these impurities and reduce wear and tear on subsequent equipment.

[0003] The existing rapeseed washing methods are mostly manual washing. When washing rapeseed, impurities such as straw will float on the surface of the liquid. When the washed rapeseed is taken out, some of the floating matter will stick to the rapeseed. The floating impurities will affect the purity of the oil in the next process. Utility Model Content

[0004] The purpose of this invention is to provide a washing device for rapeseed oil production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a washing device for rapeseed oil production, comprising a washing tank and a washing basket. The washing tank is equipped with a drive assembly, a skimming assembly, a liquid inlet pipe, and a liquid level sensor. The drive assembly includes two sets of motors, the output shafts of which are fixedly connected to cams. The washing basket is placed inside the washing tank and located above the two sets of cams. The skimming assembly includes a linear motor, the slide of which is fixedly connected to a crossbar. A skimming plate is fixedly installed on the crossbar. A slot is opened at the top of one side of the washing tank, and a slag collection box is placed at the slot.

[0006] The washing basket has steel mesh on its sides and bottom.

[0007] The washing basket has handles welded and fixed to the upper part of both sides.

[0008] The cam has a drive shaft fixedly mounted on one end, and the output shaft of the motor is fixedly connected to the drive shaft via a coupling.

[0009] The bottom of the cleaning tank is provided with an arc-shaped flow guide base.

[0010] The arc-shaped flow guide base has a pipe installed at the middle position of its lower end, and a valve is installed on the pipe.

[0011] A shelf is fixedly installed on one side of the cleaning box, and the slag collection box is placed on the shelf.

[0012] The inlet pipe is connected to the liquid delivery system.

[0013] The liquid level sensor is mounted on a bracket, which is fixedly mounted on the outer side of the cleaning tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The cam mechanism of this utility model converts rotational motion into periodic vibration. The periodic vibration is used to wash the rapeseed in the washing basket, replacing manual washing. By controlling the frequency and amplitude of the vibration, the rapeseed and impurities are separated into layers in the water, which accelerates the physical separation of impurities and rapeseed. Some impurities settle to the bottom of the washing tank, some impurities dissolve into the water, and floating impurities such as straw fragments float on the surface of the liquid.

[0016] 2. This utility model uses a liquid level sensor to detect the liquid level after washing and adds water through the inlet pipe. Floating impurities rise with the liquid surface to a specified height. The skimming plate moves linearly along the liquid surface under the drive of a linear motor, scraping the upper floating impurities into the slag collection box. When the washing basket is taken out, no floating impurities will stick to the rapeseed, thus improving the washing quality. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a washing device for rapeseed oil production, including a washing tank 1 and a washing basket 2. The washing tank 1 is equipped with a drive assembly 3, a skimming assembly 4, a liquid inlet pipe 6 and a liquid level sensor 7. The drive assembly 3 includes two sets of motors 31, the output shaft of the motors 31 is fixedly connected to cams 32. The washing basket 2 is placed inside the washing tank 1 and located above the two sets of cams 32. The skimming assembly 4 includes a linear motor 41, the slide of the linear motor 41 is fixedly connected to a crossbar 42, and a skimming plate 43 is fixedly installed on the crossbar 42. A slot 11 is opened at the upper position of one side of the washing tank 1, and a slag collection box 5 is placed at the slot 11.

[0025] A washing basket 2 containing a certain amount of rapeseed to be washed is placed in a washing tank 1. The bottom of the washing basket 2 is in contact with two sets of cams 32. When the motor 31 is working, it drives the cam 32 at one end to rotate. The cam 32 mechanism converts the rotational motion into periodic vibration. The rapeseed in the washing basket 2 is washed by periodic vibration, which replaces manual washing, saving time and effort. By controlling the frequency and amplitude of vibration, the rapeseed and impurities are separated into layers in the water, which accelerates the physical separation of impurities and rapeseed. Some impurities settle to the bottom of the washing tank 1, some impurities dissolve in the water, and floating impurities such as straw fragments float on the surface of the liquid.

[0026] After rinsing, the drive assembly 3 brakes, the liquid level sensor 7 detects the liquid level, and water is added to the washing tank 1 through the inlet pipe 6, causing the liquid level to rise. As the liquid level rises, floating impurities rise synchronously until they reach a designated height. Then, the inlet pipe 6 stops adding water, and the linear motor 41 of the skimming assembly 4 drives the crossbar 42. The crossbar 42 drives the skimming plate 43, which moves linearly along the liquid surface, scraping the floating impurities on the surface to one side and discharging them into the slag collection box 5 through the trough 11. This cleans the upper layer of floating impurities. After cleaning, the skimming assembly 4 resets, and then the washing basket 2 can be removed. Since there are no floating impurities remaining on the liquid surface, no floating impurities will adhere to the rapeseed when the washing basket 2 is removed, thus improving the rinsing quality.

[0027] The washing basket 2 has steel mesh 21 on its sides and bottom. The steel mesh 21 has mesh holes with a diameter smaller than that of the rapeseed. The washing water can enter and exit through the mesh holes of the steel mesh 21, and the rapeseed will not leak out through the mesh holes.

[0028] Handles 22 are welded and fixed to the upper part of both sides of the washing basket 2. The handles 22 facilitate the moving of the washing basket 2 in and out.

[0029] One end of the cam 32 is fixedly provided with a drive shaft 33. The output shaft of the motor 31 is fixedly connected to the drive shaft 33 through a coupling. When the motor 31 is working, it drives the cam 32 at one end to rotate. The cam 32 mechanism converts the rotational motion into periodic vibration.

[0030] The bottom of the cleaning tank 1 is equipped with an arc-shaped flow guide base 12. The flow is guided by the arc-shaped flow guide base 12. Some of the impurities washed out dissolve in the water, some settle to the bottom of the cleaning tank 1, and the other part floats on the surface of the liquid.

[0031] The arc-shaped guide base 12 has a drain pipe 13 located in the middle of its lower end. A valve 14 is installed on the drain pipe 13. When the valve 14 is opened, the drain pipe 13 is opened, and the water and sediment in the cleaning tank 1 are discharged through the drain pipe 13, which facilitates water replacement.

[0032] Among them, a shelf 15 is fixedly installed on one side of the washing box 1, and the slag collection box 5 is placed on the shelf 15. The slag collection box 5 is located at the trough opening 11. The floating matter scraped off by the slag skimmer 43 is discharged through the trough opening 11 and falls into the slag collection box 5, where it is collected. When the slag collection box 5 is almost full, it is cleaned.

[0033] The liquid inlet pipe 6 is connected to the liquid delivery system, which includes a water source and a pump body. The pump body works to deliver the rinsing water to the liquid inlet pipe 6, and then the water enters the cleaning tank 1 through the liquid inlet pipe 6 to replenish the water.

[0034] The liquid level sensor 7 is mounted on a bracket, which is fixedly set on the outer side of the cleaning tank 1. The liquid level sensor 7 accurately calculates the liquid level height by emitting a laser beam and analyzing the reflected light signal.

[0035] Working principle: In use, a washing basket 2 containing a measured amount of rapeseed to be washed is placed in the washing tank 1. The bottom of the washing basket 2 is in contact with two sets of cams 32. When the motor 31 is working, it drives one end of the cam 32 to rotate. The cam 32 mechanism converts the rotational motion into periodic vibration. The rapeseed in the washing basket 2 is washed by periodic vibration. By controlling the frequency and amplitude of the vibration, the rapeseed and impurities are separated into layers in the water, accelerating the physical separation of impurities and rapeseed. Some impurities settle to the bottom of the washing tank 1, while some impurities dissolve in the water, and straw fragments and other floating impurities... After the floating impurities are washed and rinsed, the drive assembly 3 brakes, the liquid level sensor 7 detects the liquid level, and water is added to the washing tank 1 through the inlet pipe 6 to raise the liquid level. As the liquid level rises, the floating impurities rise synchronously until they reach a specified height. Then, the inlet pipe 6 stops adding water, and the linear motor 41 of the skimming assembly 4 drives the crossbar 42. The crossbar 42 drives the skimming plate 43, which moves in a straight line along the liquid surface to scrape the floating impurities to one side and discharge them into the slag collection box 5 through the trough 11. After skimming, the skimming assembly 4 is reset, and then the washing basket 2 can be removed.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
