Description

Technical Field

[0001] The utility model belongs to the technical field of soil remediation, and particularly relates to an organic pollutant desorption device for soil remediation. Background Art

[0002] Desorption technology is an important means in the technology of contaminated soil remediation. It releases the organic pollutants adsorbed in the soil into the gas phase or liquid phase for further treatment. The main methods include thermal desorption, steam desorption, solvent desorption, and gas-driven desorption. These technologies can effectively remove various organic pollutants and restore soil quality.

[0003] However, at present, it is difficult for the organic pollutant desorption device to effectively break or disperse caked or large-particle soil. The organic pollutants adsorbed in the caked or large-particle soil are difficult to fully contact with the gas-phase or liquid-phase medium, thereby reducing the pollutant removal efficiency. Therefore, we propose an organic pollutant desorption device for soil remediation. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an organic pollutant desorption device for soil remediation, which can solve the problem that in the related technology, it is difficult for the device to effectively break or disperse caked or large-particle soil, resulting in a small soil surface area and being difficult to fully contact with the treatment agent or cleaning medium, thereby reducing the pollutant removal efficiency.

[0005] The technical solution adopted by the utility model is specifically as follows:

[0006] An organic pollutant desorption device for soil remediation includes a base. A support rod is fixedly connected to the top of the base. A desorption box body is fixedly connected to the top of the support rod. A feed pipe is fixedly connected to the top of the desorption box body. A liquid inlet pipe is fixedly connected to the outer wall of the feed pipe. A discharge pipe is fixedly connected to the side of the desorption box body. A crushing device is arranged on the side of the desorption box body. The crushing device includes a motor. The side of the motor is fixedly connected to the side of the desorption box body. The output shaft of the motor is fixedly connected to a rotating shaft. A driving rod is fixedly connected to the end of the rotating shaft away from the motor. A rotating rod is fixedly connected to the end of the driving rod away from the rotating shaft. A plurality of L-shaped crushing rods are fixedly connected to the circumferential surface of the rotating rod.

[0007] The driving rod is a threaded rod. A threaded sleeve is threadedly connected to the circumferential surface of the driving rod. An L-shaped connecting rod is fixedly connected to the outer wall of the threaded sleeve. A scraping ring is fixedly connected to the end of the L-shaped connecting rod away from the threaded sleeve.

[0008] The plurality of L-shaped crushing rods are located on the displacement trajectory of the scraping ring. A notch for the rotation of the L-shaped crushing rod is formed in the inner wall of the L-shaped connecting rod.

[0009] One end of the rotating rod away from the driving rod is provided with an anti-adhesion device. The anti-adhesion device includes a rotating block. The side surface of the rotating block is fixedly connected to one end of the rotating rod away from the driving rod. Both the left and right sides of the rotating block are fixedly connected with long rods. One ends of the two long rods away from the rotating block are fixedly connected with scraping rods.

[0010] The circumferential surface of the scraping rod is in contact with the inner wall of the desorption box body, and there is a gap between the scraping rod and the L-shaped crushing rod.

[0011] The long rod is located on the side of the L-shaped crushing rod, and there is a gap between the long rod and the L-shaped crushing rod.

During the rotation of the L-shaped crushing rod, the agglomerated or large-particle soil will be broken, so that the soil can be fully contacted with the treatment agent or cleaning medium, improving the pollutant removal efficiency; at the same time, through the cooperation of the driving rod, the threaded sleeve, the L-shaped connecting rod, and the scraping ring, the movement of the L-shaped connecting rod will drive the scraping ring to move, and the movement of the scraping ring will remove the soil adhered to the surface of the L-shaped crushing rod, thus ensuring the crushing efficiency of the L-shaped crushing rod.

[0014] Through the setting of the anti-adhesion device in the present utility model, the cooperation of the rotating block, the long rod, and the scraping rod enables the rotation of the long rod to drive the scraping rod to rotate, and the rotation of the scraping rod scrapes off the soil adhered to the inner wall of the desorption box body, thus avoiding the problem of uneven pollution removal of the organic matter inside the soil; at the same time, through the cooperation of the rotating rod and the L-shaped crushing rod, when the L-shaped crushing rod rotates, it will also mix the scraped soil with other soil to ensure uniform removal of organic matter pollution.

Detailed implementation manners

[0022] In order to make the purpose and advantages of the present utility model more clear and understandable, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0023] As Figures 1-5 shown, an organic matter pollution desorption device for soil remediation includes a base 1. A support rod 2 is fixedly connected to the top of the base 1. A desorption box body 3 is fixedly connected to the top of the support rod 2. A feed pipe 4 is fixedly connected to the top of the desorption box body 3. A liquid inlet pipe 5 is fixedly connected to the outer wall of the feed pipe 4. A discharge pipe 6 is fixedly connected to the side of the desorption box body 3. A crushing device 7 is arranged on the side of the desorption box body 3. The crushing device 7 includes a motor 71. The side of the motor 71 is fixedly connected to the side of the desorption box body 3. The output shaft of the motor 71 is fixedly connected to a rotating shaft 72. A driving rod 73 is fixedly connected to the end of the rotating shaft 72 away from the motor 71. A rotating rod 74 is fixedly connected to the end of the driving rod 73 away from the rotating shaft 72. A plurality of L-shaped crushing rods 75 are fixedly connected to the circumferential surface of the rotating rod 74.

[0024] The driving rod 73 is a threaded rod. A threaded sleeve 76 is threadedly connected to the circumferential surface of the driving rod 73. An L-shaped connecting rod 77 is fixedly connected to the outer wall of the threaded sleeve 76. An L-shaped connecting rod 77 is fixedly connected to the end of the threaded sleeve 76 away from the L-shaped connecting rod 77.

[0025] A plurality of L-shaped crushing rods 75 are located on the displacement track of the scraping ring 78. A notch for the rotation of the L-shaped crushing rod 75 is opened on the inner wall of the L-shaped connecting rod 77.

[0026] According to the above structure, the soil and the treatment agent are respectively poured into the desorption box body 3 from the feed pipe 4 and the liquid inlet pipe 5. However, the surface area of the caked or large-particle soil is small, making it difficult to fully contact the treatment agent or the cleaning medium, thus reducing the pollutant removal efficiency. Therefore, the motor 71 is started. The output shaft of the motor 71 will cause the rotating shaft 72 to rotate. The rotation of the rotating shaft 72 will drive the driving rod 73 to rotate. The rotation of the driving rod 73 will drive the rotating rod 74 to rotate. The rotation of the rotating rod 74 will drive the L-shaped crushing rod 75 to rotate. During the rotation of the L-shaped crushing rod 75, the caked or large-particle soil will be broken up, so that the soil can fully contact the treatment agent or the cleaning medium, improving the pollutant removal efficiency. The rotation of the rotating shaft 72 will drive the driving rod 73 to rotate. At the same time, the rotation of the driving rod 73 will cause the threaded sleeve 76 to move. Due to the damping effect of the soil and the treatment agent in the desorption box body 3, the threaded sleeve 76 does not completely follow the driving rod 73 to rotate. Therefore, the rotation of the driving rod 73 will cause the threaded sleeve 76 to move. By the forward and reverse intermittent rotation of the motor 71, the threaded sleeve 76 can move repeatedly, thereby driving the scraping ring 78 to move repeatedly. The repeated movement of the scraping ring 78 will remove the soil adhering to the surface of the L-shaped crushing rod 75, thus ensuring the crushing efficiency of the L-shaped crushing rod 75.

[0027] As Figures 1-5 shown, an anti-adhesion device 8 is provided at one end of the rotating rod 74 away from the driving rod 73. The anti-adhesion device 8 includes a rotating block 81. The side surface of the rotating block 81 is fixedly connected to one end of the rotating rod 74 away from the driving rod 73. Long rods 82 are fixedly connected to both the left and right sides of the rotating block 81. The ends of the two long rods 82 away from the rotating block 81 are fixedly connected to a scraping rod 83.

[0028] The circumferential surface of the scraping rod 83 is in contact with the inner wall of the desorption box body 3. There is a gap between the scraping rod 83 and the L-shaped crushing rod 75.

[0029] The long rod 82 is located on the side of the L-shaped crushing rod 75. There is a gap between the long rod 82 and the L-shaped crushing rod 75.

[0030] According to the above structure, the movement of the rotating rod 74 will drive the rotating block 81 to rotate. The rotation of the rotating block 81 will drive the long rod 82 to rotate. The rotation of the long rod 82 will drive the scraping rod 83 to rotate. The rotation of the scraping rod 83 will scrape off the soil adhering to the inner wall of the desorption box body 3, thus avoiding the problem of uneven pollution removal of the organic matter inside the soil. At the same time, when the L-shaped crushing rod 75 rotates, it will also mix the scraped soil with other soil to ensure uniform pollution removal of the organic matter.

[0031] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special explanation and limitation.
