Description

Technical Field

[0001] The utility model relates to the technical field of pulp quantity control and wear resistance, and particularly relates to a pulp quantity control damping wear-resistant device. Background Art

[0002] There are two tail discharge pipelines (one open and one closed) in the existing 45m tail thickener chamber, both of which are discharged by gravity to the pump sump of the tailings pump house, and then transported to the next process for tailings dewatering operation by a slurry pump.

[0003] The amount of pulp entering the pump sump is controlled by the opening degree of a control ceramic gate valve. Since the diameter changes when the gate is opened partially, the pulp jets out, which easily causes wear and loss of the gate and valve seat of the gate valve. In addition, the pipeline behind the gate valve is also prone to wear and perforation and slurry leakage. The service life of the ceramic gate valve and the short pipe connection behind the valve is short, the failure rate is high, the maintenance frequency is high, and the workload is large, which has a great impact on the stability of the production process. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a pulp quantity control damping wear-resistant device, which solves the technical problems that when the gate is opened partially, the diameter changes, the pulp jets out, which easily causes wear and loss of the gate and valve seat of the gate valve, and the pipeline behind the gate valve is also prone to wear and perforation and slurry leakage, and the service life of the ceramic gate valve and the short pipe connection behind the valve is short, and the failure rate is high.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0006] A pulp quantity control damping wear-resistant device includes a connecting pipeline. A wear-resistant pipeline short connection is fixedly installed at the side end of the connecting pipeline. Two bolt fixing components are fixedly installed on the outer surface of the wear-resistant pipeline short connection. A control damping wear-resistant component is arranged inside the wear-resistant pipeline short connection. A ceramic gate valve is slidably installed inside the connecting pipeline.

[0007] Preferably: Five through holes are distributed at the side end of the control damping wear-resistant component, which are installed in the outlet direction of the ceramic gate valve. Its inlet slurry section is closely attached to the ceramic gate valve. A buffer layer is fixedly installed inside the wear-resistant pipeline short connection. At least two installation holes are opened at the side end of the wear-resistant pipeline short connection. The inner wall of the wear-resistant pipeline short connection is connected to the buffer layer. One end of the control damping wear-resistant component is butted against the pulp outlet. The bolt fixing component includes a clamping seat and a rotating bolt, and the clamping seat is fixed and tightened by the rotating bolt.

[0008] The utility model has the following beneficial effects:

[0009] 1. The ceramic gate valve is driven by a motor to open partially, and the pulp is diverted through the flow control damping wear-resistant component. The flow rate will not cause jetting due to the change in pipe diameter, the impact of the pulp on the ceramic gate valve is weakened, and the problem of easy wear of the ceramic gate valve is reduced. The pulp is diverted to the wear-resistant pipe stub through the flow control damping wear-resistant component. However, the sizes of the connecting pipe and the wear-resistant pipe stub are different and are connected by a hose. Due to the change in pipe diameter, the pulp will jet inside the wear-resistant pipe stub. However, a buffer layer is installed on the inner side wall of the wear-resistant pipe stub to buffer the jetted pulp, solving the problems of short service life of the ceramic gate valve, short service life of the pipe stub behind the gate valve, and high spare part replacement cost.

[0010] 2. The ceramic gate valve, the flow control damping wear-resistant component, and the wear-resistant pipe stub are fixedly installed and connected in sequence through the bolt fixing component. The ceramic gate valve and the flow control damping wear-resistant component are both separate structures, and at the same time, the wear-resistant pipe stub is also a relatively independent structure. By rotating the bolt to make the bolt rotate out of the inside of the installation hole, it can be replaced individually when damaged, which is convenient for handling and installation, and the spare part cost is effectively controlled and saved.

[0016] In the embodiment of the present application, by providing a slurry flow control damping wear-resistant device, the problems that when a part of the gate is opened, the pipe diameter changes, the slurry sprays, which easily causes wear and loss of the gate and valve seat of the gate valve, and the pipeline behind the gate valve is also prone to wear, perforation and slurry leakage, and the service life of the ceramic gate valve and the short pipe behind the gate valve is short and the failure rate is high are effectively solved. The ceramic gate valve is driven by a motor to open partially, and the slurry is guided by the flow control damping wear-resistant component, so that the flow rate will not spray due to the change of the pipe diameter, the impact of the slurry on the ceramic gate valve is weakened, and the problem of easy wear of the ceramic gate valve is reduced. The slurry is guided by the flow control damping wear-resistant component into the wear-resistant pipe short joint. However, the sizes of the connecting pipe and the wear-resistant pipe short joint are different and are connected by a hose. Due to the change of the pipe diameter, the slurry will spray inside the wear-resistant pipe short joint. However, a buffer layer is installed on the inner side wall of the wear-resistant pipe short joint, and the buffer layer buffers the sprayed slurry, solving the problems of short service life of the ceramic gate valve, short service life of the pipe short joint behind the gate valve, and high spare part replacement cost. Embodiment

[0017] As Figures 1 - 3 As shown, the technical solution in the embodiment of the present application effectively solves the technical problems that when a part of the gate is opened, the pipe diameter changes, the slurry sprays, which easily causes wear and loss of the gate and valve seat of the gate valve, and the pipeline behind the gate valve is also prone to wear, perforation and slurry leakage, and the service life of the ceramic gate valve and the short pipe behind the gate valve is short and the failure rate is high. The general idea is as follows:

[0018] In view of the problems existing in the prior art, the present utility model provides a slurry flow control damping wear-resistant device, which includes a connecting pipe 11. A wear-resistant pipe short joint 12 is fixedly installed at the side end of the connecting pipe 11. Two bolt fixing components 13 are fixedly installed on the outer surface of the wear-resistant pipe short joint 12. A flow control damping wear-resistant component 14 is arranged inside the wear-resistant pipe short joint 12. A ceramic gate valve 15 is slidably installed inside the connecting pipe 11. The slurry is guided by the flow control damping wear-resistant component 14, so that the flow rate will not spray due to the change of the pipe diameter, the impact of the slurry on the ceramic gate valve 15 is weakened, and the problem of easy wear of the ceramic gate valve 15 is reduced. The slurry is guided by the flow control damping wear-resistant component 14 into the wear-resistant pipe short joint 12. However, the sizes of the connecting pipe 11 and the wear-resistant pipe short joint 12 are different and are connected by a hose. Due to the change of the pipe diameter, the slurry will spray inside the wear-resistant pipe short joint 12. However, a buffer layer 16 is installed on the inner side wall of the wear-resistant pipe short joint 12, and the buffer layer 16 buffers the sprayed slurry.

[0019] There are five through holes distributed on the side end of the metering damping wear-resistant component 14, which is installed in the outlet direction of the ceramic gate valve 15. Its slurry inlet section is closely attached to the ceramic gate valve 15. A buffer layer 16 is fixedly installed inside the wear-resistant pipe stub 12. At least two mounting holes 17 are provided at the side end of the wear-resistant pipe stub 12. The inner wall of the wear-resistant pipe stub 12 is connected to the buffer layer 16. The side end of the metering damping wear-resistant component 14 has five flow guiding through holes, which can be divided into upper and lower symmetric parts. According to the original gate valve opening degree, the metering damping wear-resistant component 14 can be opened by half. Its right half-curved surface is the metering hole. Among them, the ceramic gate valve 15, the metering damping wear-resistant component 14, and the wear-resistant pipe stub 12 are fixedly installed and connected by the bolt fixing component 13. The ceramic gate valve 15 and the metering damping wear-resistant component 14 are both separate structures. At the same time, the wear-resistant pipe stub 12 is also a relatively independent structure and can be replaced individually when damaged. One end of the metering damping wear-resistant component 14 is butted against the ore pulp outlet. The bolt fixing component 13 includes a clamping seat and a rotating bolt, and the clamping seat is fixed and tightened by the rotating bolt.

[0020] Working principle:

[0021] First step, the ceramic gate valve 15 is driven by the motor to open partially. The ore pulp is diverted through the metering damping wear-resistant component 14, and the flow rate will not be sprayed due to the change in pipe diameter. The impact of the ore pulp on the ceramic gate valve 15 is weakened, reducing the problem of easy wear of the ceramic gate valve 15. The ore pulp is diverted by the metering damping wear-resistant component 14 into the wear-resistant pipe stub 12. However, the sizes of the connecting pipe 11 and the wear-resistant pipe stub 12 are different and are connected by a hose. Due to the change in pipe diameter, the ore pulp will be sprayed inside the wear-resistant pipe stub 12. However, a buffer layer 16 is installed on the inner side wall of the wear-resistant pipe stub 12, and the buffer layer 16 buffers the sprayed ore pulp, improving the service life of the metering damping wear-resistant component 14 and the wear-resistant pipe stub 12, achieving the metering damping effect on the ore pulp and the wear-resistant effect. At the same time, the side end of the metering damping wear-resistant component 14 has five flow guiding through holes, which can be divided into upper and lower symmetric parts. According to the original gate valve opening degree, the metering damping wear-resistant component 14 can be opened by half. Its right half-curved surface is the metering hole. Among them, the ceramic gate valve 15, the metering damping wear-resistant component 14, and the wear-resistant pipe stub 12 are fixedly installed and connected by the bolt fixing component 13. The ceramic gate valve 15 and the metering damping wear-resistant component 14 are both separate structures. At the same time, the wear-resistant pipe stub 12 is also a relatively independent structure and can be replaced individually when damaged, which is convenient for handling and installation, and the spare part cost is effectively controlled and saved.

[0022] Finally, it should be noted that: Obviously, the above embodiments are merely examples given to clearly illustrate the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
