Description

TECHNICAL FIELD

[0001] The application relates to the field of contaminated soil remediation and treatment, in particular to a soil remediation device. BACKGROUND

[0002] Soil is an important production and environmental element, and is one of the natural resources on which human beings and the natural environment rely for survival. With the rapid development of economy, frequent industrial activities have led to a large amount of dyes entering the soil environment. Among them, the more common ones include plastic pollution and pesticide pollution. In actual pollution situations, soil is often subjected to composite pollution, for example, land seriously polluted by pesticides is also subjected to a certain degree of plastic pollution. When the soil subjected to composite pollution is remediated, if the more serious one of the pollutions is mainly treated, the remaining pollution still exists.

[0003] Taking the above situation as an example, if only the pesticide pollution existing in the soil is treated, the soil is transported into the soil remediation equipment, the soil and the liquid medicine are mixed, the pesticide existing in the soil is degraded and decomposed, in order to fully mix the soil and the liquid medicine, a cutting knife is arranged in the soil remediation equipment to cut the soil, so that the soil is mixed with the liquid medicine in a relatively loose state, and a stirring blade is further arranged to mix the soil and the liquid medicine. Under the action of the cutting knife and the stirring blade, the plastic bags existing in the soil are broken, which further increases the difficulty of subsequent treatment of plastic pollution. SUMMARY

[0004] The purpose of the application is to provide a soil remediation device which can treat plastic pollution while remedying pesticide pollution, so as to ensure that the soil can be well remedied.

[0005] The soil remediation device provided by the application adopts the following technical scheme:

[0007] The filtering plate and the first driving shaft are both fixed in the feeding bin, the plurality of cams are all sleeved on the first driving shaft and are arranged in one-to-one correspondence with the plurality of piercing rods, the circumferential wall of the cam abuts against one end of the piercing rod and drives the piercing rod to move vertically, and the piercing hole for the piercing rod to pass through is formed in the filtering plate.

[0008] By adopting the above technical scheme, when the contaminated soil enters the feed bin, it will pass through the filter assembly for filtering, and when the soil is on the filter plate, a part of the relatively loose soil will pass through the piercing hole into the treatment bin, and the continuously rotating cam will push the piercing rod, which will pass through the piercing hole and pierce into the soil to remove the garbage such as plastic bags existing in the soil from the soil, thereby ensuring that the soil can be better repaired.

[0009] Optionally, the bottom side of the filter plate is provided with an intercepting cage, the intercepting cage is sleeved on the piercing rod, and the intercepting cage comprises a plurality of first connecting rods and second connecting rods, the plurality of first connecting rods are arranged around the piercing rod and are hingedly arranged in one-to-one correspondence with the plurality of second connecting rods, and a third connecting rod is arranged between each of the plurality of second connecting rods and the piercing rod, and the two ends of the third connecting rod are hingedly connected with the second connecting rod and the piercing rod, respectively.

[0010] By adopting the above technical scheme, during the vertical upward movement of the piercing rod, the piercing rod drives the third connecting rod to move, so that the third connecting rod drives the second connecting rod to move towards the direction close to the piercing rod, and the intercepting cage is gathered to the center, thereby ensuring that the piercing rod can pass through and intercepting the garbage removed from the soil by the last piercing rod, and in the same way, during the vertical downward movement of the piercing rod, the intercepting cage expands outward, thereby ensuring that the garbage can smoothly enter the intercepting cage.

[0011] Optionally, the feed bin is connected with a fixing frame, the plurality of first connecting rods are connected to the fixing frame, a convex edge is arranged around the piercing rod, and a first elastic element is sleeved on the piercing rod, one end of the first elastic element abuts against the convex edge, and the other end of the first elastic element abuts against the bottom wall of the fixing frame.

[0012] By adopting the above technical scheme, the fixing frame fixes the intercepting cage and combines with the convex edge to constrain the first elastic element, so that the first elastic element is compressed when the piercing rod moves vertically upward, and the first elastic element can adaptively rebound when the piercing rod moves vertically downward, thereby ensuring that the cam can stably drive the piercing rod to move.

[0013] Optionally, the piercing rod is hollow and internally provided with a plurality of intercepting rods, the plurality of intercepting rods are rotationally connected with the piercing rod, one end of the intercepting rod is connected with a movable block, and the other end of the intercepting rod is connected with an intercepting block, and the piercing rod is provided with an avoiding hole for the movable block and the intercepting block to extend out of.

[0014] The bottom side of the fixing frame is fixedly connected with an ejection sleeve sleeved on the piercing rod, and when the piercing rod moves vertically, the ejection sleeve can abut against the movable block and drive the intercepting rod to rotate, so that the intercepting block extends out of the avoiding hole.

[0016] Optionally, one end of the piercing rod abutting against the cam is provided in a hemispherical shape and symmetrically provided with two protective plates, both of which are connected with the piercing rod and abut against the outer sidewall of the cam.

[0017] By adopting the technical scheme, the protective plates protect the cam and prevent the soil passing through the filter plate from accumulating on the cam, so as to ensure that the cam drives the piercing rod to move stably.

[0018] Optionally, it further comprises a disentangling assembly for disentangling soil, which comprises a second driving shaft, a spiral blade and a driving piece, the second driving shaft is inserted into the feeding bin, the driving piece is connected outside the feeding bin and drives the second driving shaft to rotate, and the spiral blade is sleeved on the second driving shaft.

[0019] By adopting the technical scheme, when the plastic garbage such as plastic is removed from the contaminated soil, a small part of soil enters the processing bin from the piercing hole of the filter plate, and the remaining soil falls to the position where the disentangling assembly is located, and is disentangled by the spiral blade, so that the soil is loosened and the pesticide residues in the soil can be removed by mixing the soil with the chemical liquid.

[0020] Optionally, the outlet end of the feeding bin is provided with a screening piece, which comprises a screen plate provided with a plurality of mesh holes and a vibration motor connected with the screen plate.

[0021] By adopting the technical scheme, after the soil is conveyed, the stones and wood carried by the soil are intercepted by the screening of the screening piece.

[0022] Optionally, the processing bin is provided with a conveying frame and a conveying belt, the conveying frame is inclined and connected with the processing bin, and the conveying belt is arranged around the conveying frame and used to drive the soil to move.

[0023] Through the above technical scheme, after the soil enters into the treatment bin, the soil falls on the conveying frame, the conveying belt on the conveying frame transports the soil, and the storage bin inputs the liquid medicine into the treatment bin to mix with the soil on the conveying belt.

[0024] Optionally, a plurality of rotary cutters are arranged in the treatment bin and connected with the treatment bin.

[0025] Through the above technical scheme, after the liquid medicine is mixed with the soil, the rotary cutters can mix the soil and the liquid medicine, so that the liquid medicine can better remove the pesticide pollution in the soil.

[0026] In summary, the present application has at least one of the following beneficial technical effects:

[0027] 1. When the contaminated soil enters the feeding bin, the soil is filtered by the filter assembly. When the soil is on the filter plate, a part of the relatively loose soil can pass through the piercing hole into the treatment bin. The continuously rotating cam pushes the piercing rod, which passes through the piercing hole and pierces into the soil, to remove the garbage such as plastic bags in the soil, so that the soil can be better repaired.

[0028] 2. During the vertical upward movement of the piercing rod, the piercing rod moves the third connecting rod, so that the third connecting rod moves the second connecting rod towards the piercing rod, and the interception cage is gathered to the center. While ensuring that the piercing rod is pierced out, the garbage removed by the last piercing rod is intercepted. Similarly, during the vertical downward movement of the piercing rod, the interception cage expands outward to ensure that the garbage can enter the interception cage smoothly.

[0029] 3. When the piercing rod is not in the working state, the elastic element is in the normal extension state, the interception block is in the piercing rod, and the corresponding avoidance hole is not extended. When the movable block contacts the inner wall of the ejection sleeve, the movable block is squeezed into the piercing rod. At this time, the interception rod rotates to make the interception block extend out of the avoidance hole to intercept the plastic bag on the piercing rod, so that the plastic bag can be brought into the interception cage by the piercing rod. During the process of bringing the plastic bag into the interception cage, the interception block at the lowest end slides out of the ejection sleeve. At this time, the spring rebounds to make the interception block at the highest end re-enter the piercing rod, so that the plastic bag is no longer intercepted. BRIEF DESCRIPTION OF DRAWINGS
