Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, specifically to a crushing and mixing device for soil remediation agents. Background Technology

[0002] In the field of environmental remediation, soil remediation agents are increasingly widely used, and the crushing of raw materials is a crucial step in the preparation process. Crushing the raw materials increases their specific surface area, enhancing their contact efficiency with pollutants and thus improving the remediation effect.

[0003] Utility model patent CN202323136838.7 discloses a raw material shearing and crushing device for soil remediation agent production. This device includes a crushing box, a conveying box, a feed inlet, and a discharge outlet. Support feet are installed at the four corners of the bottom of the crushing box. A feed inlet is located in the center of the top of the crushing box, and a discharge outlet is located in the center of the bottom of the crushing box. A first motor is installed on both sides of the feed inlet at the top of the crushing box. The output end of the first motor is connected to a first rotating shaft inside the crushing box. Several crushing rods are evenly installed on the surface of the first rotating shaft. Symmetrical guide plates are installed below the first rotating shaft on the inner wall of the crushing box. Two shearing rollers are symmetrically installed below the guide plates on the inner wall of the crushing box. Several shearing blades are evenly installed on the surface of the shearing rollers. A filter screen is installed below the shearing rollers. A conveying box is installed on the side of the crushing box. A second motor is installed on the top of the conveying box. The output end of the second motor is connected to a second rotating shaft inside the conveying box. Spiral conveying blades are installed on the surface of the second rotating shaft. This invention first achieves preliminary crushing of raw materials for soil remediation agent production through the staggered rotation of crushing rods. Then, the pre-processed raw materials are conveyed to the shearing rollers by the guide plate. The shearing rollers rotate, driving the shearing blades to further shear and crush the raw materials. The sheared raw materials fall into the filter screen. Through the vibration of the vibrating motor, the qualified raw materials are conveyed out through the discharge port, while the unqualified raw materials enter the conveying box through the inlet. The spiral conveyor blades then convey the unqualified raw materials back to the crushing rods through the outlet for further processing until the raw materials are qualified. The above structural design effectively crushes the raw materials for soil remediation agent production, ensuring the effectiveness of the soil remediation agent.

[0004] Although the raw material shearing and crushing device for soil remediation agent production is beneficial for crushing raw materials, it still has the following problems in practical use: In the processing of soil remediation agents, the pretreatment of raw materials is crucial, typically including crushing, screening, and mixing steps. However, the current device only has crushing and screening structures, lacking integrated mixing functionality. This design necessitates transferring the raw materials to a separate mixing device after crushing and screening. This process not only increases the number of steps but also prolongs the processing cycle, thus affecting the overall production efficiency of soil remediation agents. Therefore, we propose a crushing and mixing device for soil remediation agents. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] This embodiment provides a technical solution:

[0032] Please see Figures 1-5As shown, a crushing and mixing device for soil remediation agents includes a crushing section 1. The crushing section 1 includes a hollow housing 10. A vertical shaft 12 is rotatably mounted on the upper part of the housing 10. Multiple crushing blades 120 are coaxially keyed to the outer wall of the vertical shaft 12, and the top end of the vertical shaft 12 passes through the top of the housing 10. Two symmetrical crushing rollers 13 are rotatably mounted on the lower part of the housing 10. A connecting shaft 130 is coaxially keyed to the end of each crushing roller 13, and the connecting shaft 130 located at the front passes through the outer wall of the housing 10. A screening box 2 is provided below the crushing section 1. The screening box 2 has a hollow structure and is connected to the housing 10. A discharge bin 20, connected to the bottom of the screening box 2, is installed. A screen plate 21 is provided inside the screening box 2. A screen 22 is installed in the middle notch of the screen plate 21. Connecting rods 23 are slidably installed at the four corners of the screen plate 21. Springs 24 for pressing against the screen plate 21 are sleeved on the upper and lower sides of the connecting rods 23. A bracket 25 is fixed between the bottom ends of two adjacent connecting rods 23. A vibrating motor 26 is also installed at the bottom edge of the screen plate 21. A mixing pipe 3 is provided below the screening box 2. The mixing pipe 3 is connected to the discharge bin 20. An auger 30 for conveying and mixing soil remediation agent raw materials is rotatably installed inside the mixing pipe 3. A first motor 31 for driving the auger 30 to rotate is installed at the front end of the mixing pipe 3. A discharge pipe 32 is fixed at the front end of the outer wall of the mixing pipe 3. A transmission mechanism 4 is provided on the front side of the crushing section 1. The transmission mechanism 4 includes two symmetrical pulley assemblies, each of which includes two symmetrical pulleys 40. A belt 41 is fitted between two adjacent pulleys 40. The lower pulley 40 is coaxially keyed to the connecting shaft 130 located on the front side. The upper pulley 40 is coaxially keyed to the transmission shaft 42. The rear end of the transmission shaft 42 is coaxially keyed to the first bevel gear 43. The rear side of the first bevel gear 43 meshes with a second bevel gear 44. The second bevel gear 44 is coaxially keyed to the top end of the vertical shaft 12. A second motor 45 for driving the transmission shaft 42 to rotate is also installed on the upper front side of the housing 10. Through the pulley assembly, the power of the second motor 45 can be transmitted to the transmission shaft 42, thereby driving the vertical shaft 12 and the crushing blade 120 to rotate, and simultaneously driving the crushing roller 13 to rotate, ensuring that the vertical shaft 12 and the crushing blade 120 can operate efficiently and form a synergistic crushing effect with the crushing roller 13.

[0033] In this embodiment, inclined guide plates 100 are fixed to both the left and right side walls inside the housing 10, and the guide plates 100 are located above the crushing roller 13. The inclined design of the guide plates 100 optimizes the material flow direction, ensuring that the crushed raw materials can enter the crushing roller 13 area evenly, improving crushing efficiency, while reducing the possibility of material blockage and accumulation, and improving the stability and continuity of the equipment.

[0034] In this embodiment, a maintenance compartment is provided at the bottom of the front end of the housing 10, and a compartment door 14 is fixedly connected to the maintenance compartment by bolts. The bolt connection ensures the airtightness of the compartment door 14 and simplifies the disassembly and assembly process; and by removing the compartment door 14, it is convenient to open the screening box 2, thereby facilitating the cleaning of the screen 22.

[0035] In this embodiment, a feeding hopper 11 is installed on the top of the housing 10, and the overall shape of the feeding hopper 11 is funnel-shaped. The funnel-shaped feeding hopper 11 design improves the material feeding efficiency and reduces raw material splashing and waste.

[0036] In this embodiment, the bottom four corners of the screening box 2 are all fixedly connected with support legs by bolts, and the overall shape of the support legs is cylindrical. The cylindrical support legs are fixedly connected by bolts, which enhances the stability and shock resistance of the equipment, while also facilitating installation and adjustment, adapting to the needs of different working environments, and improving the adaptability of the equipment.

[0037] In this embodiment, the transmission mechanism 4 also includes a hollow protective cover, which is fixed to the front side wall of the housing 10, and the pulley assembly is located inside the protective cover. The design of the protective cover effectively prevents dust and foreign objects from entering the pulley assembly, extends the service life of the transmission mechanism 4, improves the safety of the equipment, reduces operational risks, and meets industrial safety standards.

[0038] In this embodiment, the brackets 25 are fixedly connected to the inner bottom of the screening box 2 by bolts, and the two opposite end faces of the two brackets 25 are inclined. The bolted connection ensures the stability and reliability of the structure; while the inclined surface design serves to guide the material, facilitating the material to enter the discharge hopper 20 for discharge.

[0039] It is understood that in this embodiment, the upper and lower walls of the screening box 2 are provided with connecting grooves. The upper connecting groove is connected to the inside of the box body 10, and the lower connecting groove is connected to the discharge bin 20. This design facilitates the smooth falling of the crushed raw materials. At the same time, the discharge bin 20 in this embodiment is wider at the top and narrower at the bottom. This design facilitates the falling raw materials to converge into the mixing pipe 3, thereby facilitating the discharge and mixing of the raw materials.

[0040] Furthermore, in this embodiment, the output shafts of the two second motors 45 rotate in opposite directions when they are running. This design allows the two crushing rollers 13 inside the housing 10 to rotate synchronously relative to each other, thereby facilitating the crushing of raw materials.

[0041] It is worth noting that the first motor 31 and the second motor 45 involved in this embodiment are existing conventional technologies, and will not be described in detail here.

[0042] In practical use, the operator first connects the power supply to the first motor 31 and the second motor 45. The first motor 31 and the second motor 45 then begin operation. The output shaft of the first motor 31 rotates, driving the auger 30 to rotate. The output shaft of the second motor 45 rotates, driving the transmission shaft 42. The transmission shaft 42 then drives the first bevel gear 43 and the upper pulley 40 to rotate. The first bevel gear 43 drives the second bevel gear 44 to rotate. The second bevel gear 44 simultaneously drives the vertical shaft 12 and multiple crushing blades 120 to rotate. Simultaneously, driven by the belt 41, the lower pulley 40 rotates, driving the connecting shaft 130 and the crushing roller 13 to rotate. Subsequently... The user feeds the raw materials into the feeding hopper 11, where they fall into the housing 10. Under the action of the rotating crushing blade 120, the raw materials are initially crushed. Under the action of the rotating crushing roller 13, the raw materials are then crushed a second time. The crushed raw materials fall onto the screen 22, where the vibrating motor 26 vibrates and drives the screen plate 21 to vibrate. The screen 22 then screens the raw materials. At the same time, the qualified raw materials fall into the discharge bin 20 and enter the mixing pipe 3. As the auger 30 rotates, it drives the raw materials to move horizontally and mix them together. Finally, the mixed raw materials are discharged to the outside through the discharge pipe 32.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
