Description

Technical Field

[0001] This utility model relates to the field of soil pollution remediation technology, and in particular to a crushing and dispersing device for soil pollution remediation. Background Technology

[0002] Soil pollution remediation is a complex process, and soil testing is an indispensable part of it. Soil testing provides information such as the soil's pollution status, the types and concentrations of pollutants, and other crucial data for developing a scientifically sound remediation plan. The remediation process involves determining the remediation goals for the contaminated site based on the testing results, selecting appropriate remediation technologies, implementing remediation projects, and verifying their effectiveness. Therefore, soil testing plays a vital role in soil pollution remediation, and the testing process requires breaking down and dispersing the soil.

[0003] A search revealed Chinese Patent Publication No. CN215624768U, which discloses a soil crushing and screening device for soil pollution remediation. The device includes a screening host. Four No. 1 motors are fixedly installed in a rectangular shape on the upper part of one side wall of the screening host. The four No. 1 motors are arranged in pairs. The output ends of the two pairs of No. 1 motors are respectively fixed with a No. 1 rotating rod and a No. 2 rotating rod. The ends of the No. 1 rotating rods and the No. 2 rotating rods that are away from the No. 1 motors all penetrate through the screening host and extend into the interior of the screening host.

[0004] Existing technologies similar to the soil crushing devices described above only use a dispersing wheel and a compaction wheel to crush the soil, which can easily result in uneven soil crushing and affect the accuracy of soil testing. Therefore, there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a soil crushing and dispersing device for soil pollution remediation. Its advantages lie in employing a three-stage process to complete soil crushing, thereby improving the uniformity of soil pulverization and increasing the accuracy of soil testing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A crushing and dispersing device for soil pollution remediation includes a crushing box, a feeding hopper at the top of the crushing box, mounting plates at the middle of the inner walls on both sides of the crushing box, a rotary motor at the bottom outer wall of the mounting plates, a crushing cone connected to the output shaft of the rotary motor, a plurality of equally spaced crushing teeth on the outer wall of the crushing cone, and fixing blocks on both sides of the inner wall at the top of the crushing box. The fixing blocks have a right-angled trapezoidal cross-section, and a plurality of equally spaced crushing blades are arranged on the inclined surface of the fixing blocks.

[0008] The two fixed blocks are rotatably connected to the same dispersing wheel on opposite outer walls. The dispersing wheel is driven by an electric motor. A grinding chamber is provided on the bottom outer wall of the crushing box. Two grinding rollers are rotatably connected to the inner wall of the grinding chamber. The two grinding rollers rotate relative to each other. Both grinding rollers are driven by a servo motor. A discharge port is provided on both sides of the top of the mounting plate. The discharge port is connected to the grinding chamber through a discharge pipe. A collection box is provided at the bottom of the crushing box.

[0009] The above technical solution involves the following steps: During operation, the soil to be crushed is fed into the crushing chamber through the feed hopper. The motor drives the dispersing wheel to rotate, breaking larger soil clumps into smaller pieces. A rotating motor drives the crushing cone to rotate, further crushing the smaller soil clumps into smaller particles under the action of the crushing teeth and blades. The crushed particles then enter the grinding chamber through the feed pipe. A servo motor drives the grinding rollers to rotate, and under the action of the two grinding rollers, the soil is thoroughly ground into powder. The powder then enters the collection box. This three-stage process completes the soil crushing, improving the uniformity of soil crushing and increasing the accuracy of soil testing.

[0010] The present invention is further configured such that baffle plates are hinged to the inner walls on both sides of the feed hopper, and the baffle plates are connected to the feed hopper through a return spring.

[0011] The above technical solution, namely the installation of retaining plates, can effectively block the splashed soil during soil breaking, thus preventing soil from splashing out.

[0012] The present invention is further configured such that the retaining plate has an arc-shaped structure.

[0013] The above technical solution, with its arc-shaped structure, allows soil to fall easily down the retaining plate, improving the convenience of material feeding.

[0014] The present invention is further configured such that the dispersing wheel includes a rotating roller, the rotating roller is connected to the output shaft of the motor, the outer wall of the rotating roller is provided with a plurality of dispersing columns distributed at equal intervals, and the end of the dispersing column away from the rotating roller is provided with a dispersing head.

[0015] The above technical solution works as follows: when the dispersing wheel rotates, it drives the dispersing column to rotate, and the rotation of the dispersing column drives the dispersing head to rotate. The dispersing head breaks the soil into small pieces, thus improving the soil dispersing effect.

[0016] The present invention is further configured such that a guide block is provided at the top of the crushing cone, and the top of the guide block has an arc surface structure.

[0017] The above technical solution, namely the setting of the diversion block, can easily disperse the broken soil to both sides, avoiding soil retention.

[0018] The present invention is further configured such that baffles are provided on both sides of the grinding chamber, and the baffles are located above the grinding roller.

[0019] The above technical solution involves setting up a baffle to facilitate the distribution of soil between the two grinding rollers, thereby improving the grinding effect.

[0020] The present invention is further provided that a maintenance door is hinged to one side of the crushing box, and a handle is provided on the outer wall of the maintenance door.

[0021] The above technical solution, with its inspection door, allows for easy access to the crushing chamber for internal maintenance, thus improving the convenience of maintenance.

[0022] The present invention is further provided that the outer wall of the inspection door is provided with an observation opening, and the inner wall of the observation opening is provided with an observation window.

[0023] The above technical solution, with its observation window, allows for convenient observation of the working conditions inside the crushing chamber, improving operational ease.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. This soil pollution remediation crushing and dispersing device works by feeding the soil into the crushing chamber through the feed hopper. The motor drives the dispersing wheel to rotate, breaking larger soil clumps into smaller pieces. The control motor drives the crushing cone to rotate, and as the crushing cone rotates, the smaller soil clumps are gradually crushed into smaller pieces by the crushing teeth and crushing blades. The crushed material enters the grinding chamber through the feed pipe. The servo motor drives the grinding roller to rotate, and the soil is thoroughly ground into powder by the two grinding rollers. The powder enters the collection box. The soil crushing is completed in three stages, which improves the uniformity of soil crushing and increases the accuracy of soil testing.

[0026] 2. The soil pollution remediation crushing and dispersing device has a soil retaining plate that can easily block the splashed soil during crushing, preventing soil from splashing out; a guide block that can easily disperse the crushed soil to both sides, preventing soil from accumulating; and a baffle block that can easily guide the soil between the two grinding rollers, improving the grinding effect.
