Description

Technical Field

[0001] This utility model relates to the field of soil remediation equipment technology, and in particular to a soil heavy metal remediation mixing device suitable for confined spaces. Background Technology

[0002] In the process of soil heavy metal remediation, it is often necessary to use a mixing device to fully mix the remediation agent with the contaminated soil in order to stabilize or remove the heavy metals.

[0003] Traditional mixing devices have many limitations in confined spaces such as small urban plots, building perimeters, and underground areas: they are bulky and cannot be disassembled, making them difficult to transport through narrow passages; their fixed height makes them unsuitable for low and narrow working spaces; they require a high degree of ground flatness during operation and are prone to wobbling on uneven ground; and their installation and disassembly steps are cumbersome, with difficulty in removing fixing components such as ground nails. Utility Model Content

[0004] This utility model relates to a soil heavy metal remediation mixing device suitable for narrow spaces, which solves the problems of traditional mixing devices being difficult to transport in narrow spaces, having no adjustable height, poor ground adaptability, and being cumbersome to install and disassemble.

[0005] This utility model provides a soil heavy metal remediation mixing device suitable for narrow spaces, specifically including: a base; two first rotating shafts are rotatably mounted on the base, and the inner sides of the two first rotating shafts are welded to a connecting seat. The connecting seat has a ring structure, and a mixing barrel is inserted into the connecting seat. A retaining ring is welded onto the mixing barrel, and the bottom end face of the retaining ring contacts the top end face of the connecting seat. A locking screw for locking the mixing barrel is threaded onto the connecting seat.

[0006] Furthermore, a base block is welded to one of the first rotating shafts on the right side, and a pin is inserted into the base block, which is then inserted into the base.

[0007] Furthermore, a cover plate is fixed to the top of the mixing tank, a second rotating shaft is rotatably mounted on the cover plate, an impeller is mounted on the second rotating shaft, a motor is fixed to the upper end face of the cover plate, and the output shaft of the motor is fixed to the second rotating shaft.

[0008] Furthermore, the base has four threaded rods that rotate, and each threaded rod has a support seat at one end, with all four support seats in contact with the ground.

[0009] Furthermore, an adjustment block is welded to one of the upper ends of each threaded rod, and all four adjustment blocks are hexagonal block structures.

[0010] Furthermore, four ground nails are inserted into the base, all of which are inserted into the soil. Each ground nail has an auxiliary seat welded on it. All four auxiliary seats are concave in shape, and the lower end of each of the four auxiliary seats is in contact with the base.

[0011] This invention provides a soil heavy metal remediation mixing device suitable for confined spaces, which has the following beneficial effects: In terms of adaptability to narrow spaces, this application adopts a detachable design. When transported to a narrow location, the mixing tank can be pulled out and separated from the connecting seat, which greatly reduces the transportation volume and facilitates passage through narrow passages. At the same time, the mixing tank can be rotated by pulling out the pin, which reduces the overall height of the device and easily adapts to low and narrow working spaces, solving the problems of difficult transportation and poor space adaptability of traditional devices.

[0012] In terms of mixing efficiency and convenience, this application uses a motor to drive a second rotating shaft to rotate the impeller at high speed, which can quickly achieve uniform mixing of soil and remediation agent. Compared with manual mixing or traditional simple devices, the mixing efficiency is significantly improved. The mixing tank is quickly locked and fixed by a locking screw, and the installation and disassembly steps are simple, requiring no complicated tools and effectively saving preparation time.

[0013] In terms of operational stability and adaptability, this application features a base equipped with four adjustable threaded rods. The height of the support can be adjusted by rotating the adjustment block, easily adapting to uneven ground and ensuring stable operation without shaking. Four ground nails are inserted into the soil to firmly fix the base. Combined with the concave structure of the auxiliary seat, this ensures the stability of the device during operation and allows for quick removal of the ground nails using a pry bar. This balances installation firmness with ease of disassembly, comprehensively improving the efficiency and practicality of heavy metal remediation operations in confined spaces.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0021] Example 1: Please refer to Figures 1 to 4 : This utility model proposes a soil heavy metal remediation mixing device suitable for confined spaces, comprising: a base 1; two first rotating shafts 101 rotatably mounted on the base 1, the inner sides of which are welded to a connecting seat 102, the connecting seat 102 being annular in structure, a mixing tank 2 inserted into the connecting seat 102, a retaining ring 201 welded onto the mixing tank 2, the bottom end face of the retaining ring 201 contacting the top end face of the connecting seat 102, and a locking screw 202 threadedly connected to the connecting seat 102 for locking the mixing tank 2. When transported to a confined space for use, the mixing tank 2 can be pulled out from the connecting seat 102 for disassembly and transportation, thus facilitating the use of this device in confined spaces.

[0022] A base block 103 is welded to a first rotating shaft 101 on the right side. A pin 104 is inserted into the base block 103 and is inserted into the base 1. When the device moves to a narrow position, the pin 104 is pulled out and then the stirring tank 2 is rotated. At this time, the height of the device is reduced, which makes it easier for the device to pass through the narrow position.

[0023] The mixing tank 2 has a cover plate 203 fixed on top, a second rotating shaft 204 rotating on the cover plate 203, an impeller 205 mounted on the second rotating shaft 204, a motor 206 fixed on the upper end face of the cover plate 203, and the output shaft of the motor 206 fixed on the second rotating shaft 204. When mixing is achieved, the motor 206 is driven to rotate, and the motor 206 drives the second rotating shaft 204 and the impeller 205 to rotate to achieve mixing.

[0024] The base 1 has four threaded rods 3 that rotate, and each threaded rod 3 has a support seat 301 at one end. All four support seats 301 are in contact with the ground. When the device is moved to the use position, rotating the four threaded rods 3 can adjust the base 1, thereby adapting to uneven ground.

[0025] Each threaded rod 3 has an adjustment block 302 welded to one end of its upper part. All four adjustment blocks 302 are hexagonal block structures. When rotating the threaded rod 3, a wrench can be used to engage with the adjustment block 302 for adjustment, which is convenient and quick.

[0026] Example 2, based on Example 1, such as Figures 1 to 4 As shown, four ground nails 4 are inserted into the base 1. All four ground nails 4 are inserted into the soil. Each ground nail 4 is welded with an auxiliary seat 401. All four auxiliary seats 401 are concave structures. The lower end of each of the four auxiliary seats 401 is in contact with the base 1. When removing the ground nails 4, a pry bar is inserted between the auxiliary seat 401 and the base 1 and pried. This improves the disassembly efficiency of the base 1.

[0027] The working principle of this embodiment is as follows: During transportation, loosen the locking screw 202 to pull out the mixing bucket 2, disassemble it, and transport it separately. If encountering a low passage, pull out the pin 104 and rotate the mixing bucket 2 to lower its height, allowing it to pass through narrow spaces smoothly. After arriving at the work position, place the base 1 stably, use a wrench to engage the adjusting block 302 and rotate the threaded rod 3, adjusting the base 1 to a horizontal state via the support base 301. Then, insert four ground nails 4 into the soil to fix the base 1. Pour the soil to be repaired and the repair agent into the mixing bucket 2, and insert the mixing bucket 2 into the connecting... Connect the base 102, ensuring the retaining ring 201 fits against the top surface of the connecting base 102, and tighten the locking screw 202 to lock the mixing tank 2; start the motor 206, which drives the second rotating shaft 204 to rotate the impeller 205, uniformly mixing the soil and remediation agent; after the operation is completed, turn off the motor 206, loosen the locking screw 202, remove the mixing tank 2 and pour out the mixture, insert the pry bar between the auxiliary base 401 and the base 1 to pry out the ground nail 4, disassemble the components and transport them away, thus completing the entire operation process.
