Harmless treatment device for waste water-based mud

Abstract

The utility model relates to the technical field of slurry harmless treatment devices, in particular to a waste water-based slurry harmless treatment device which comprises a machine frame, and two sets of plate chain shafts are rotationally connected to the surface of the machine frame. The plate chain has the beneficial effects that when the plate chain enters a bending position caused by the driving wheel, the previous group of plate chain rotates around the connecting rod, so that one end of each tooth on the surface of the next group of plate chain is warped out of a tooth groove in the surface of the previous group of plate chain, and soil on the surfaces of the teeth is connected with soil which is not located on the surfaces of the teeth at the periphery under the action of viscosity; as the plate chain runs continuously, the soil which is separated from the plate chain slides downwards under the action of the gravity of the soil and drives the soil on the surfaces of the teeth to slide downwards under the action of the viscosity of the soil, so that all the soil is separated from the plate chain, and the soil on the surfaces of the teeth is separated from the plate chain. And therefore, the waste water-based mud harmless treatment device is more thorough in discharging.

Description

Technical Field

[0001] The utility model relates to the field of mud harmless treatment devices, in particular to a waste water-based mud harmless treatment device. Background Art

[0002] A large amount of waste mud will be generated during the construction process of drilling and other projects. If the waste mud is discharged directly, it will cause pollution to the environment. Therefore, the waste mud needs to be harmlessly treated before disposal. Waste mud is divided into water-based and oil-based types, among which the treatment of water-based mud is relatively simple.

[0003] In the prior art, waste water-based mud is generally treated by a filter press. During the treatment process, the filter press plays a role in solid-liquid separation. Specifically, the filter press slurry pump will suck the mud that has been pre-treated (such as gel breaking, drug addition and flocculation, etc.) and transport it to the filter press for filtration. The clear liquid after filtration can be transported to a storage tank, while the solid phase is transported to an underground tank or other designated area by a belt conveyor for further treatment or disposal. The solid phase is the soil after pressure drying.

[0004] However, when conveying soil through a belt conveyor, the soil after filter pressing often has greater viscosity, which causes the soil to adhere to the surface of the belt, so that part of the soil cannot fall off the belt after reaching the discharge end of the belt conveyor, resulting in incomplete unloading. Utility Model Content

[0005] The utility model aims to provide a device for harmlessly treating waste water-based mud to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for harmless treatment of waste water-based mud, comprising: a frame, two groups of plate chain shafts are rotatably connected on the surface of the frame, a driving wheel and a driven wheel are respectively mounted and fixed on the surfaces of the two groups of plate chain shafts, the driven wheel is arranged below the discharge port of the filter press, a motor is fixed on the surface of the frame, the transmission shaft of the motor is connected to a group of plate chain shafts on which the driving wheel is mounted, a plurality of groups of plate chains are arranged between the driving wheel and the driven wheel, a plurality of groups of teeth are arranged at one end of the plate chain, a plurality of groups of tooth grooves are opened at the other end of the plate chain, the teeth arranged on the surface of one group of plate chains are rotatably connected in the tooth grooves opened on the surface of the other group of plate chains.

[0007] Preferably, connection holes are provided on the surface of the plate chain, and a plurality of groups of plate chains are connected to the connecting rods through the connection holes to form a chain.

[0008] Preferably, a cleaning wheel shaft is rotatably connected to the surface of the frame, and a belt transmission mechanism is provided between the cleaning wheel shaft and the transmission shaft of the motor.

[0009] Preferably, a cleaning wheel is sleeved and fixed on the shaft body of the cleaning wheel shaft, and a plurality of groups of bristles are arranged on the surface of the cleaning wheel. The bristles are evenly distributed on the surface of the cleaning wheel, and the bristles at the top end of the cleaning wheel are against the surface of the plate chain.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The waste water-based mud harmless treatment device proposed by the utility model, the motor drives the plate chain shaft to rotate on the surface of the frame, and the plate chain shaft drives the driving wheel to rotate, thereby driving the chain composed of the plate chain to reciprocate between the driving wheel and the driven wheel, the mud discharged from the discharge port of the filter press is piled on the chain composed of the plate chain, and is transported from the side close to the driven wheel to the side close to the driving wheel, and then the unloading is completed from the side close to the driving wheel. When the plate chain enters the bending position caused by the driving wheel, the front group of plate chains rotates around the connecting rod, so that the surface of the rear group of plate chains One end of the tooth sticks out from the tooth groove on the surface of the previous group of plate chains. Under the action of viscosity, the soil on the tooth surface is connected to the surrounding soil that is not on the tooth surface, which makes the soil not on the tooth surface be lifted up and thus separated from the surface of the plate chain. As the plate chain continues to run, the soil that has separated from the plate chain slides downward under the action of its own gravity, and at the same time, under the action of its own viscosity, it drives the soil on the tooth surface to slide downward, so that all the soil is separated from the plate chain, making the unloading of the waste water-based mud harmless treatment device more thorough.

[0017] Embodiment 1

[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: a harmless treatment device for waste water-based mud, comprising: a frame 1, two groups of plate chain shafts 8 are rotatably connected on the surface of the frame 1, and a driving wheel 2 and a driven wheel 3 are respectively sleeved and fixed on the surfaces of the two groups of plate chain shafts 8, and the driven wheel 3 is arranged below the discharge port of the filter press. A motor 9 is fixed on the surface of the frame 1, and the transmission shaft of the motor 9 is connected to a group of plate chain shafts 8 sleeved with the driving wheel 2, and a plurality of groups of plate chains 4 are arranged between the driving wheel 2 and the driven wheel 3, and a plurality of groups of teeth 6 are arranged at one end of the plate chain 4, and a plurality of groups of tooth grooves 7 are opened at the other end of the plate chain 4, wherein the teeth 6 arranged on the surface of one group of plate chains 4 are rotatably connected to the tooth grooves 7 opened on the surface of another group of plate chains 4, and a connecting hole is opened on the surface of the plate chain 4, and a plurality of groups of plate chains 4 are formed into a chain through the cooperation of the connecting hole and the connecting rod 5.

[0019] In actual use, the motor 9 drives the plate chain shaft 8 to rotate on the surface of the frame 1, and the plate chain shaft 8 drives the driving wheel 2 to rotate, thereby driving the chain composed of the plate chain 4 to reciprocate between the driving wheel 2 and the driven wheel 3. The soil discharged from the discharge port of the filter press is piled on the chain composed of the plate chain 4 and transported from the side close to the driven wheel 3 to the side close to the driving wheel 2, and then the unloading is completed from the side close to the driving wheel 2. When the plate chain 4 enters the bending position caused by the driving wheel 2, the front group of plate chains 4 rotates around the connecting rod 5, so that the teeth 6 on the surface of the rear group of plate chains 4 One end sticks out from the tooth groove 7 on the surface of the previous group of plate chains 4. Under the action of viscosity, the soil on the surface of the teeth 6 is connected to the surrounding soil that is not on the surface of the teeth 6, which makes the soil that is not on the surface of the teeth 6 be lifted up and thus separated from the surface of the plate chain 4. As the plate chain 4 continues to run, the soil that has been separated from the plate chain 4 slides downward under the action of its own gravity, and at the same time, under the action of its own viscosity, it drives the soil on the surface of the teeth 6 to slide downward, so that all the soil is separated from the plate chain 4, making the unloading of the waste water-based mud harmless treatment device more thorough.

[0020] Embodiment 2

[0021] On the basis of Example 1, in order to further remove the dirt on the surface of the plate chain 4 at the unloading end, a cleaning wheel shaft 11 is rotatably connected to the surface of the frame 1, and a belt transmission mechanism 10 is arranged between the cleaning wheel shaft 11 and the transmission shaft of the motor 9. A cleaning wheel 12 is fixedly mounted on the shaft body of the cleaning wheel shaft 11, and a plurality of groups of bristles 13 are arranged on the surface of the cleaning wheel 12. The bristles 13 are evenly distributed on the surface of the cleaning wheel 12, and the bristles 13 at the top of the cleaning wheel 12 are against the surface of the plate chain 4.

[0022] The transmission shaft of the motor 9 drives the cleaning wheel shaft 11 to rotate on the surface of the frame 1 through the belt transmission mechanism 10, and the cleaning wheel shaft 11 drives the cleaning wheel 12 to rotate. The rotation of the cleaning wheel 12 causes several groups of bristles 13 to continuously scrape the surface of the plate chain 4, so that the residual soil on the surface of the plate chain 4 is cleaned, thereby achieving further removal of the soil on the surface of the plate chain 4 at the unloading end.

[0023] In actual use, the motor 9 drives the plate chain shaft 8 to rotate on the surface of the frame 1, and the plate chain shaft 8 drives the driving wheel 2 to rotate, thereby driving the chain composed of the plate chain 4 to reciprocate between the driving wheel 2 and the driven wheel 3. The soil discharged from the discharge port of the filter press is piled on the chain composed of the plate chain 4, and is transported from the side close to the driven wheel 3 to the side close to the driving wheel 2, and then the unloading is completed from the side close to the driving wheel 2. When the plate chain 4 enters the bending position caused by the driving wheel 2, the front group of plate chains 4 rotates around the connecting rod 5, so that one end of the teeth 6 on the surface of the rear group of plate chains 4 is tilted out from the tooth groove 7 on the surface of the front group of plate chains 4. Under the action of viscosity, the soil on the surface of the teeth 6 is connected with the surrounding soil that is not on the surface of the teeth 6, which makes the soil not on the surface of the teeth 6 The mud on the surface is lifted up and separated from the surface of the plate chain 4. As the plate chain 4 continues to run, the mud that has been separated from the plate chain 4 slides down under the action of its own gravity, and at the same time, under the action of its own viscosity, it drives the mud on the surface of the teeth 6 to slide down, so that all the mud is separated from the plate chain 4, making the unloading of the waste water-based mud harmless treatment device more thorough; the transmission shaft of the motor 9 drives the cleaning wheel shaft 11 to rotate on the surface of the frame 1 through the belt transmission mechanism 10, and the cleaning wheel shaft 11 drives the cleaning wheel 12 to rotate. The rotation of the cleaning wheel 12 causes several groups of bristles 13 to continuously scrape the surface of the plate chain 4, so that the residual mud on the surface of the plate chain 4 is cleaned, and the mud on the surface of the plate chain 4 is further removed at the unloading end.
