Description

Technical Field

[0001] The utility model relates to the technical field of organic material purification, in particular to an organic material purification and concentration device. Background Art

[0002] Materials composed of elements such as carbon, hydrogen, oxygen, and nitrogen are collectively referred to as organic materials. The process of mixed thermal processing of organic materials is: deliberately mixing two or more materials together to form a mixed liquid containing organic matter and heating and stirring it to form other products. In the purification of mixed organic materials, it is often necessary to mix them to form a mixed liquid, which undergoes a high-temperature heating and stirring process.

[0003] In the process of heating the existing organic materials, a purification tank with a heating function is generally used to heat and mix the organic materials. In the existing method, a heating component is generally set in the purification tank to heat the inner wall of the tank body. However, when the organic material in the purification tank is small, the inner wall of the upper side of the purification tank cannot effectively heat the organic material directly (because when the organic material is small, the material cannot contact the upper inner wall of the tank body), which will cause a waste of heat energy. Moreover, after the upper side of the purification tank is dry-burned for a period of time, once the organic material splashes on it, it is easy to overheat the organic material, thereby affecting the purification effect of the organic material.

[0079] The plurality of sealing arc plates 18 are fixedly sleeved on the outer surfaces of the plurality of fixing blocks 16 and the plurality of sealing blocks 17 .

[0080] Furthermore, the sealing arc plate 18 is in an arc shape, and the inner wall of the sealing arc plate 18 contacts the outer surface of the rotating block 6;

[0081] Among them, a plurality of fixing holes 19 are provided on the outer surface of the rotating block 6;

[0082] Wherein, a plurality of bolts 15 are threadedly sleeved on the outer surfaces of a plurality of sealing arc plates 18;

[0083] The end of the bolt 15 close to the rotating block 6 slides and extends into the fixing hole 19;

[0084] Wherein, a plurality of heating rods 14 are fixedly connected to the outer surface of a side of a plurality of fixed blocks 16 away from the rotating block 6;

[0085] Furthermore, the interior of the heating rod 14 is hollow, and an electric heating tube is arranged inside the heating rod 14. The electric heating tube includes an electric heating alloy wire, a metal tube shell, etc. The electric heating tube is electrically connected to the first contact piece 20. The interior of the rotating block 6 is hollow, and a connecting wire is arranged inside the rotating block 6. The connecting wire is made of high temperature resistant material and is electrically connected to the second contact piece 21. A controller is arranged outside the purification tank 2. The upper end of the connecting wire passes through the interior of the rotating block 6 and out of the purification tank 2 and is electrically connected to the controller. The controller controls the start and stop of the electric heating tube.

[0086] Furthermore, the electric heating tube is a commonly used heating structure and will not be described in detail here.

[0087] Furthermore, the first contact piece 20 and the second contact piece 21 are both made of conductive materials. When the fixing block 16 slides into the connecting groove 22 to make the first contact piece 20 contact the second contact piece 21, the connection is electrically energized through the controller. With the cooperation of the first contact piece 20 and the second contact piece 21, the heating rod 14 is energized, thereby heating the organic material in the purification tank 2, and concentrating and purifying the organic material.

[0088] Furthermore, when the amount of organic material to be concentrated and purified is small, it is necessary to install the fixed block 16 on the upper side in the connecting groove 22 on the lower side, first start the electric push rod 3, and the electric push rod 3 drives the cover 4 and the rotating block 6 to move up and down, so that the rotating block 6 and the contacts installed thereon are moved out of the purification tank 2. At this time, it is necessary to remove the sealing block 17 on the lower side, and screw the two bolts 15 on the corresponding sealing arc plate 18 out of the corresponding fixing holes 19. At this time, the corresponding lower sealing block 17 can be pulled out of the lower connecting groove 22. At this time, the corresponding bolts 15 need to be rotated according to the same principle, and then the fixed block 16 on the upper side is pulled out of the upper connecting groove 22. At this time, the fixing block 16 located on the upper side is slid into the connecting groove 22 located on the lower side, thereby realizing the replacement position of the heating rod 14. In the same principle, the height of the heating rod 14 can also be increased, and the height of the heating rod 14 can be adapted to the height of the current organic material, so that the heating rod 14 can be properly immersed in the organic material, and when there is less organic material in the purification tank 2, the heating rod 14 that is not immersed in the organic material is prevented from being dry-burned. On the one hand, it avoids the waste of heat energy, and on the other hand, it can prevent the organic material from splashing onto the heating rod 14 and causing overheating, thereby improving the energy-saving performance of the device and increasing the practicality of the device;

[0089] As mentioned above, the function of the sealing block 17 is to seal the connection groove 22 that is not connected to the fixing block 16, so as to prevent the second contact piece 21 from being directly exposed in the purification tank 2 and causing leakage. The sealing block 17 is made of insulating material and will not conduct electrical energy with the second contact piece 21, thereby ensuring the practicality of the device.

[0090] Furthermore, in this solution, several sealing blocks 17 and structures thereon should be provided. When there is too little organic material in the purification tank 2, several heating rods 14 can be appropriately removed, and the corresponding connecting grooves 22 can be sealed using the provided sealing blocks 7 and structures thereon.

[0091] Furthermore, the scraper 13 can scrape off the organic material adhering to the inner wall of the purification tank 2, thereby ensuring the uniformity of the purification of the organic material, thereby ensuring the efficiency and quality of the purification of the organic material, thereby increasing the practicality of the concentration device;

[0092] Furthermore, when in use, the motor 10 is started, and the motor 10 starts to drive the connecting block 11 to rotate, and then synchronously drives the support column 12 to rotate around the rotating output shaft of the motor 10. During the rotation of the support column 12, it slides in the support groove 9, and then drives the support block 8 to perform reciprocating fan-shaped motion, and then synchronously drives the rotating block 6 to perform reciprocating fan-shaped rotation, and then synchronously drives the heating rod 14 to stir and heat the organic material in the purification tank 2 on the one hand, and also drives the scraper 13 to scrape the inner wall of the purification tank 2. The support column 12, support block 8, support groove 9, motor 10 and connecting block 11 cooperate to make the rotating block 6 perform reciprocating fan-shaped rotation, mainly to avoid knotting and entanglement of the connection electrical properties in the rotating block 6 during circular motion, thereby ensuring the practicality of the device.

[0093] Working principle: When the device is in use, when the amount of organic material to be concentrated and purified is small, the fixed block 16 on the upper side needs to be installed in the connecting groove 22 on the lower side, and the electric push rod 3 is started first. The electric push rod 3 drives the cover 4 and the rotating block 6 to move up and down, so that the rotating block 6 and the contacts installed thereon are moved out of the purification tank 2. At this time, the sealing block 17 on the lower side needs to be removed, and the two bolts 15 on the corresponding sealing arc plate 18 need to be screwed out of the corresponding fixing holes 19. At this time, the corresponding lower sealing block 17 can be pulled out of the lower connecting groove 22. At this time, the corresponding bolts 15 need to be rotated according to the same principle, and the fixed block 16 on the upper side is pulled out of the upper side. In the connecting groove 22, the fixing block 16 located on the upper side is slid into the connecting groove 22 located on the lower side, thereby realizing the replacement position of the heating rod 14. In the same principle, the height of the heating rod 14 can also be adjusted to be adapted to the height of the current organic material, so that the heating rod 14 can be properly immersed in the organic material, and the heating rod 14 that is not immersed in the organic material is prevented from being dry-burned when there is less organic material in the purification tank 2. On the one hand, it avoids the waste of heat energy, and on the other hand, it can prevent the organic material from splashing onto the heating rod 14 and causing overheating, thereby improving the energy-saving performance of the device and increasing the practicality of the device;

[0094] As mentioned above, the function of the sealing block 17 is to seal the connection groove 22 that is not connected to the fixing block 16, so as to prevent the second contact piece 21 from being directly exposed in the purification tank 2 and causing leakage. The sealing block 17 is made of insulating material and will not conduct electrical energy with the second contact piece 21, thereby ensuring the practicality of the device.
