Description

Technical Field

[0001] The present application relates to the technical field of soil remediation agent production, and more specifically, to a soil remediation agent impurity removal barrel and a method for using the same. Background Art

[0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. It can be roughly divided into three methods: physical, chemical and biological. When producing and processing soil remediation agents, various organic and inorganic substances are generally subjected to operations such as impurity removal, mixing, stirring, heating, granulation and drying. When removing impurities from the raw materials of soil remediation agents, filters and other equipment are generally installed inside the barrel. The raw materials of soil remediation agents are filtered through filters and other equipment, so that impurities remain on the filters, thereby removing impurities from the raw materials of soil remediation agents.

[0003] The document with the prior art publication number CN218459666U provides a de-impurity barrel for soil remediation agent production. The device can make the rotating rod drive the horizontal plate and the first crushing roller to rotate through the operation of the motor, and cooperate with the second crushing roller inside the installation tube to break up the blocky soil remediation agent raw materials, preventing the first crushing roller from pushing the blocky soil remediation agent raw materials to move, making it inconvenient to break them up. The crushed soil remediation agent raw materials can be filtered into the inside of the placement barrel through the filter net at the bottom, so that impurities are separated from the soil remediation agent raw materials.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: during the use of the above-mentioned prior art soil remediation agent production impurity removal barrel, the first crushing roller used for crushing the soil remediation agent raw material and installed at the bottom end of the horizontal plate is mostly connected by bolts or welding. When the first crushing roller used for crushing the raw material is damaged, it is difficult for people to disassemble and replace the damaged first crushing roller, which prolongs the maintenance time of the soil remediation agent impurity removal barrel, thereby delaying the subsequent soil remediation agent crushing work, resulting in a decrease in the production efficiency of the soil remediation agent.

[0005] With respect to the above-mentioned related technologies, the inventor believes that the present application can crush the soil remediation agent raw materials poured into the outer barrel through the coordinated operation between the rotating part and the fixed crushing rollers arranged in pairs, and when the dynamic crushing structure in the rotating part is damaged, people can quickly remove the dynamic crushing structure from the rotating part through the roller head assembly in the dynamic crushing structure and reinstall the new dynamic crushing structure back on the rotating part. The operation is simple and convenient, which makes it convenient for people to disassemble, assemble and replace the dynamic crushing structure when it is damaged.

[0006] In view of this, we propose a soil remediation agent impurity removal barrel and a method for using the same. Summary of the invention

[0018] The upper and lower parts of the side wall of the roller mounting seat are provided with threaded connection parts.

[0019] As an optional solution of the technical solution of the present application document, the limiting pin rod is located between two threaded connection parts provided on the side wall of the roller mounting seat.

[0020] As an optional solution of the technical solution of the present application document, a screw groove cooperating with the threaded connection part and capable of being threadedly connected to the roller mounting seat is provided at the bottom of the strip-shaped rotating seat;

[0021] The side wall of the screw groove is provided with an annular groove in which one end of the limiting pin rod away from the arc end can be movably buckled. When the roller mounting seat is threadedly connected in the screw groove and the top end of the roller mounting seat abuts against the top wall of the screw groove, the end of the limiting pin rod is aligned with the annular groove.

[0022] By adopting the above technical scheme, the present application can crush the soil remediation agent raw materials poured into the outer barrel through the cooperation between the rotating part and the fixed crushing rollers arranged in pairs, and when the dynamic crushing structure in the rotating part is damaged, people can quickly remove the dynamic crushing structure from the rotating part through the roller head assembly in the dynamic crushing structure and reinstall the new dynamic crushing structure back on the rotating part. The operation is simple and convenient, which makes it convenient for people to disassemble, assemble and replace the dynamic crushing structure when it is damaged.

[0023] As an optional solution of the technical solution of the present application document, the roller rod assembly includes a roller body fixedly connected to the bottom of the roller mounting seat, an electric heating rod is connected to the inside of the roller body at the position of the central axis, and the top end of the electric heating rod penetrates into the inner cavity of the roller mounting seat;

[0024] A plurality of knife accommodating cavities are evenly arranged inside the roller body, and a crushing knife is arranged inside each knife accommodating cavity;

[0025] The side wall of the electric heating rod and the corresponding position of each knife accommodating cavity are connected with a heat conduction terminal, and the heat conduction terminal is away from one end of the electric heating rod and extends into the corresponding knife accommodating cavity;

[0026] An opening and closing sealing structure is provided at the opening of the knife accommodating cavity;

[0027] A connecting cavity is provided inside the roller body at a position corresponding to each knife accommodating cavity, and the connecting cavity is located above the corresponding knife accommodating cavity. A small pressure relief hole is opened on the side wall of the roller body at a position corresponding to the connecting cavity, and the small pressure relief hole is connected to the corresponding connecting cavity, and a filter is connected inside the small pressure relief hole.

[0028] As an optional solution of the technical solution of the present application document, one end of the connecting cavity is connected to the corresponding knife accommodating cavity, and the other end is connected to the inner cavity of the roller mounting seat.

[0029] By adopting the above technical scheme, the raw materials for preparing the soil remediation agent are poured into the outer barrel and the drive motor and the electric heating rod are started at the same time. The dynamic crushing structure is driven to rotate by the drive motor, and then the dynamic crushing structure enters between the paired fixed crushing rollers and rotates at high speed to crush the raw materials between the paired fixed crushing rollers. After the electric heating rod is turned on, the raw materials being crushed are heated and dried by the heated roller body, so as to improve the dryness of the raw materials and facilitate the dynamic crushing structure to crush the raw materials.

[0030] As an optional solution of the technical solution of the present application document, the crushing blade element includes a blade end piston which is sealingly and slidably connected to the inside of the blade accommodating chamber, the end of the blade end piston close to the opening of the blade accommodating chamber is connected to the crushing blade, the end of the crushing blade away from the blade end piston is symmetrically provided with two chamfered transition portions A, the end of the blade end piston away from the crushing blade is connected to a tension spring, and the end of the tension spring away from the connected blade end piston is connected to the inner wall of the blade accommodating chamber.

[0031] By adopting the above technical solution, the heat conduction terminal continuously transfers the heat energy generated by the turned-on electric heating rod to the inner cavity of the knife accommodating chamber. The air pressure in the knife accommodating chamber increases, pushing the crushing tool out of the knife accommodating chamber, and the crushing tool protruding from the side wall of the roller body further reduces the distance between the roller rod assembly and the two fixed crushing rollers, thereby further enhancing the crushing effect on the raw materials.

[0032] As an optional solution of the technical solution of the present application document, the opening and closing sealing structure includes door plate grooves symmetrically arranged on the left and right sides of the knife accommodating cavity, and a closed plate door is slidably connected in the door plate groove, and telescopic springs are connected to the opposite ends of the two closed plate doors, and the end of the telescopic spring away from the connected closed plate door is connected to the inner wall of the corresponding door plate groove;

[0033] Two chamfered transition portions B are symmetrically arranged on one end of the closed panel door away from the telescopic spring.

[0034] By adopting the above technical scheme, after the raw material crushing work is completed, the driving motor and the electric heating rod are turned off, and the gas in the inner cavity of the roller mounting seat that was originally expanded by heat gradually contracts due to the cold and drives the driving conical end head to move downward. Under the action of the return spring elastic force, the limit pin rod is disengaged from the annular groove, so that people can easily remove the dynamic crushing structure from the strip rotating seat. When the electric heating rod is turned off, the gas in the knife accommodating chamber also gradually contracts due to the cold. Driven by the elastic force of the stretch spring and the gradually reduced air pressure in the knife accommodating chamber, the crushing tool retracts into the knife accommodating chamber to avoid being damaged by collision with hard objects due to long-term exposure to the environment. Subsequently, under the action of the telescopic spring elastic force, the two closed panel doors gradually move toward each other and close the opening at the end of the knife accommodating chamber, shielding the liquid or moisture in the environment outside the knife accommodating chamber, thereby realizing anti-corrosion protection for the crushing tool shrunk in the knife accommodating chamber, and further improving the protection effect of the crushing tool used for crushing the raw materials of the soil remediation agent.

[0035] As an optional solution of the technical solution of the present application document, a sealing strip is connected to the end of the closed panel door away from the connected telescopic spring.

[0036] By adopting the above technical solution, when the two closed panel doors are closed, the gap between the two closed panel doors is sealed by the sealing strip, thereby increasing the sealing performance of the opening and closing sealing structure after closing.

[0037] The technical solution of the present application provides a soil remediation agent impurity removal barrel, comprising the following steps:

[0038] S1. Pour the raw materials for preparing the soil remediation agent into the outer barrel and start the driving motor and the electric heating rod at the same time;

[0039] S2, the dynamic crushing structure is driven to rotate by a driving motor, and then the dynamic crushing structure enters between the paired fixed crushing rollers and rotates at high speed to crush the raw materials between the paired fixed crushing rollers;

[0040] S3. After the electric heating rod is turned on, the raw material being crushed is heated and dried by the heated roller body to improve the dryness of the raw material, making it easier for the dynamic crushing structure to crush the raw material;

[0041] S4, the electric heating rod in working state transfers heat energy to the inner cavity of the roller mounting seat, and after the air pressure in the inner cavity of the roller mounting seat increases, the air floating piston drives the tapered end to move upward;

[0042] S5, the continuously upward-moving driving conical end pushes the locking pin rod to move horizontally and snap into the annular locking groove in the screw groove;

[0043] S6. The heat energy conduction terminal continuously transfers the heat energy generated by the turned-on electric heating rod to the inner cavity of the knife accommodating chamber. The air pressure in the knife accommodating chamber increases, and the crushing cutter is pushed out of the knife accommodating chamber. The crushing cutter protruding from the side wall of the roller body further reduces the distance between the roller rod assembly and the two fixed crushing rollers, thereby further enhancing the crushing effect on the raw materials.

[0044] S7. After the crushed raw materials are filtered through the filter, the crushed raw material particles with a particle size smaller than the filter mesh aperture pass through the filter mesh and fall into the collection box, while the raw materials with a particle size larger than the filter mesh aperture are retained on the surface of the filter mesh, waiting for another crushing process.

[0045] 3. Beneficial effects

[0046] One or more technical solutions provided in the technical solution of this application have at least the following technical effects or advantages:

[0047] 1. The present application can crush the soil remediation agent raw materials poured into the outer barrel through the cooperation between the rotating part and the fixed crushing rollers arranged in pairs, and when the dynamic crushing structure in the rotating part is damaged, people can quickly remove the dynamic crushing structure from the rotating part through the roller head assembly in the dynamic crushing structure and reinstall the new dynamic crushing structure back on the rotating part. The operation is simple and convenient, which makes it convenient for people to disassemble, assemble and replace the dynamic crushing structure when it is damaged.

[0048] 2. After the raw materials for preparing the soil remediation agent are poured into the outer barrel, the drive motor and the electric heating rod are started at the same time. The dynamic crushing structure is driven to rotate by the drive motor, and then the dynamic crushing structure enters between the paired fixed crushing rollers and rotates at high speed to crush the raw materials between the paired fixed crushing rollers. After the electric heating rod is turned on, the raw materials being crushed are heated and dried by the heated roller body to improve the dryness of the raw materials, which is convenient for the dynamic crushing structure to crush the raw materials.

[0049] 3. The electric heating rod in working state transfers heat energy to the inner cavity of the roller mounting seat. When the air pressure in the inner cavity of the roller mounting seat increases, the air floating piston pushes the driving conical end to move upward. The continuously upward driving conical end pushes the limiting pin to move horizontally and snap into the annular groove in the screw groove. As a result, the dynamic crushing structure installed on the strip rotating seat by threaded connection can use the heat energy of the electric heating rod that heats the raw material to snap the limiting pin into the annular groove in the screw groove after installation, thereby realizing the anti-loosening treatment of the dynamic crushing structure installed in the screw groove, so that the dynamic crushing structure can be firmly installed and fixed in the screw groove on the strip rotating seat, thereby further enhancing the connection firmness of the dynamic crushing structure.

[0050] 4. The heat energy conduction terminal continuously transfers the heat energy generated by the turned-on electric heating rod to the inner cavity of the knife accommodating chamber. The air pressure in the knife accommodating chamber increases, pushing the crushing tool out of the knife accommodating chamber, and the crushing tool protruding from the side wall of the roller body further reduces the distance between the roller rod assembly and the two fixed crushing rollers. This allows the device to heat and dry the raw materials through the electric heating rod, and at the same time, it can further use the heat energy of the electric heating rod to dynamically reduce the distance between the roller rod assembly and the two fixed crushing rollers, thereby enhancing the fineness of the raw material crushing, which is beneficial to enhancing the crushing effect of the raw materials.

[0051] 5. After the raw material crushing work is completed, turn off the drive motor and the electric heating rod. The gas in the inner cavity of the roller mounting seat that was originally expanded by heat gradually contracts due to cooling and drives the driving conical end to move downward. Under the action of the elastic force of the reset spring, the limit pin rod is disengaged from the annular groove, making it convenient for people to disassemble the dynamic crushing structure from the strip rotating seat.

[0052] 6. When the electric heating rod is turned off, the gas in the knife accommodating chamber gradually contracts due to the cold. Driven by the elastic force of the extension spring and the gradually decreasing air pressure in the knife accommodating chamber, the crushing tool retracts into the knife accommodating chamber to avoid being exposed to the environment for a long time and being damaged by collision with hard objects. Subsequently, under the action of the elastic force of the extension spring, the two closed panels gradually move toward each other and close the opening at the end of the knife accommodating chamber, shielding the liquid or moisture in the environment outside the knife accommodating chamber, thereby achieving anti-corrosion protection for the crushing tool retracted in the knife accommodating chamber, and further improving the protection effect of the crushing tool used for crushing the raw materials of the soil remediation agent.

The electric heating rod 310 in the working state transfers heat energy to the inner cavity of the roller mounting seat 302. After the air pressure in the inner cavity of the roller mounting seat 302 increases, the air floating piston 305 pushes the driving conical end 306 to move upward. The continuously upward driving conical end 306 pushes the locking pin 307 to move horizontally and snap into the annular groove in the screw groove. As a result, the dynamic crushing structure installed on the strip rotating seat 301 by a threaded connection can use the heat energy of the electric heating rod 310 that heats the raw material to snap the locking pin 307 into the annular groove in the screw groove after installation, thereby realizing the anti-loosening treatment of the dynamic crushing structure installed in the screw groove, so that the dynamic crushing structure can be firmly installed and fixed in the screw groove on the strip rotating seat 301, thereby further enhancing the connection firmness of the dynamic crushing structure. The heat conduction terminal 316 continuously transfers the heat energy generated by the turned-on electric heating rod 310 to the inner cavity of the knife accommodating chamber 322. The air pressure in the inner cavity of the knife accommodating chamber 322 increases, pushing the crushing tool 311 out of the inside of the knife accommodating chamber 322, and the crushing tool 311 protruding from the side wall of the roller body 303 further reduces the distance between the roller rod assembly and the two fixed crushing rollers 6, so that the device can heat and dry the raw materials through the electric heating rod 310, and at the same time, it can further use the heat energy of the electric heating rod 310 to dynamically reduce the distance between the roller rod assembly and the two fixed crushing rollers 6, thereby enhancing the fineness of the crushing of the raw materials, which is beneficial to enhancing the crushing effect of the raw materials.

[0075] After the raw material crushing work is completed, the drive motor 7 and the electric heating rod 310 are turned off. The gas in the inner cavity of the roller mounting seat 302 that was originally expanded by heat gradually contracts due to cooling and drives the driving conical end 306 to move downward. Under the elastic force of the return spring 309, the limit pin rod 307 is disengaged from the annular groove, making it convenient for people to disassemble the dynamic crushing structure from the strip rotating seat 301. When the electric heating rod 310 is turned off, the gas in the knife accommodating chamber 322 gradually shrinks due to the cold. Driven by the elastic force of the extension spring 313 and the gradually decreasing air pressure in the knife accommodating chamber 322, the crushing tool 311 retracts to the inside of the knife accommodating chamber 322 to avoid being damaged by collision with hard objects due to long-term exposure to the environment. Subsequently, under the action of the elastic force of the extension spring 321, the two closed panel doors 312 gradually move toward each other and close the end opening of the knife accommodating chamber 322, shielding the liquid or moisture in the environment outside the knife accommodating chamber 322, thereby realizing anti-corrosion protection for the crushing tool 311 retracted inside the knife accommodating chamber 322.
