Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal preparation plant soaking technology, and in particular to coal bunker soaking components and automated soaking systems. Background Technology
[0002] The basic method of water infiltration in raw coal bunkers at coal preparation plants is top-down infiltration. Specifically, a pipe is connected to the top of the bunker near the center to create a circular infiltration system against the bunker wall. However, because the nozzles are not in the exact center and the water pressure in the rubber hoses is limited, this method cannot guarantee that all water will reach the bunker wall, easily leading to water leakage. For coal preparation plants with many large-scale raw coal mines, insufficient buffering capacity in the raw coal bunker will severely affect unloading and coal return efficiency. Simultaneously, the reduced buffering capacity of the bunker inevitably reduces the flexibility of raw coal blending for washing, which to some extent affects the quality of the washed products.
[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0004] The technical problem to be solved by this utility model is to solve the problem of the nozzle being unable to concentrate and accurately spray water into the reservoir.
[0005] This utility model solves the above-mentioned technical problems through the following technical means:
[0006] This utility model claims protection for a coal bunker sump assembly. The bunker body has a sump cavity with at least two outlets at the bottom. The assembly is characterized by including a first pipe, a first valve, a power source, a second pipe, and a fluid source. The first pipe is arranged circumferentially around the middle of the outer wall of the bunker body, and its inlet is connected to the fluid source via the power source. The second pipe is arranged correspondingly to the outlets, with its inlet connected to the first pipe and its outlet connected to the middle of the sump cavity. The second pipe is equipped with the first valve.
[0007] By setting a first pipe in the middle of the outer wall of the warehouse body, and then coordinating with a second pipe and an outlet arranged accordingly, with the outlet of the second pipe connected to the middle of the warehouse cavity, the ink spray nozzle is directly aimed at the warehouse wall, resulting in concentrated and precise ink spraying. Furthermore, by setting a corresponding first valve for each second pipe, the targeting of ink spraying can be effectively improved by opening and closing the corresponding first valve, greatly reducing the workload and difficulty of ink spraying.
[0008] Preferably, each outlet corresponds to at least two second pipes, and the outlet ends of the at least two second pipes are arranged symmetrically along the outlet.
[0009] The installation of a second pipe allows for a wider coverage area during soaking.
[0010] Preferably, a first through hole is radially penetrating the middle of the outer wall of the warehouse body. The first through hole and the second pipe are arranged in a one-to-one correspondence. One end of the second pipe is connected to the first pipe to form the inlet of the second pipe, and the other end of the second pipe passes through the first through hole and is connected to the warehouse cavity to form the outlet of the second pipe.
[0011] By setting a first through hole, a platform is set around the middle of the outer wall of the warehouse body in a circumferential direction, and a first pipe is set on the platform.
[0012] The platform can be configured to securely install the first pipe.
[0013] Preferably, it also includes an anti-blocking unit. The platform is equipped with an anti-blocking unit, which is arranged correspondingly to the outlet. The outlet of the anti-blocking unit is connected to the middle of the cavity, and the outlet of the anti-blocking unit is staggered from the outlet of the second pipe.
[0014] The anti-blocking unit is preferably an air cannon, which works by outputting a strong airflow to make the coal fall from the inner wall of the warehouse body into the outlet.
[0015] Preferably, the warehouse body between two adjacent first through holes is radially penetrated by a second through hole, and the air outlet pipe of the anti-blocking unit passes through the second through hole and communicates with the warehouse cavity to form the outlet of the anti-blocking unit.
[0016] The second through hole allows the outlet of the anti-blocking unit to be directly connected to the chamber cavity for soaking.
[0017] Preferably, a baffle is provided at the bottom of the silo cavity, and the baffle surface and the inner wall of the silo body enclose an outlet, which has a conical hole structure.
[0018] The conical outlet structure ensures that coal falls naturally under gravity, reducing coal adhesion to the surface of the storage chamber or the outlet.
[0019] Preferably, the bottom of the chamber has a conical hole structure, and a baffle is installed inside the conical hole. The baffle has a cross-shaped cross section and the cross section area increases uniformly downwards. The adjacent baffles and the chamber enclose a conical outlet.
[0020] The shape of the baffle can be set according to the actual situation, and it can be either straight or star-shaped. Of course, different baffle shapes will result in different numbers and sizes of exits. For example, when the baffle is straight, two exits will be generated. Therefore, the actual working conditions and the size of the warehouse body can be considered together to make adaptive adjustments.
[0021] Preferably, it also includes a connecting water pipe, a power source is set at the bottom of the outer wall of the warehouse body, one end of the first pipe is connected to the connecting water pipe, the other end of the connecting water pipe is connected to the fluid source through the power source to form the inlet of the first pipe, and a second valve is set in the connecting water pipe.
[0022] The main function of the connecting water pipe is to connect the fluid source and the first pipe. The water source is pumped to the middle of the warehouse body by the power source and enters the first pipe, and then flows out through the second pipe.
[0023] This utility model also claims protection for an automated coal bunkering system, which uses coal bunkering components, including a control unit, a first valve being a solenoid valve, and the control unit being configured to control the opening and closing of the solenoid valve.
[0024] The solenoid valve is controlled by a control unit to open and close automatically, thus greatly reducing the workload of personnel. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0031] See Figure 1 and Figure 2 This utility model claims protection for a coal bunker soaking assembly, which is mainly used for soaking operations on the main body of the bunker 1. The outer wall of the main body of the bunker 1 is cylindrical, and a bunker cavity is set inside. The bottom of the bunker cavity has a conical hole structure, and a cross-shaped baffle 10 is set in the middle of the conical hole. The baffle 10 is inclined outward and downward. The adjacent baffle 10 and the bunker cavity enclose to form four conical hole-shaped outlets, which are, in clockwise order, the first outlet 11a, the second outlet 11b, the third outlet 11c, and the fourth outlet 11d.
[0032] The conical orifice structure of the silo and outlet ensures that coal falls naturally under gravity, reducing coal adhesion to the silo surface or outlet. The shape of the baffle 10 can be set in a straight line or a star shape depending on the actual situation. Of course, different shapes of the baffle 10 will result in different numbers and sizes of outlets. For example, when the baffle 10 is straight, two outlets are generated. Therefore, the actual working conditions and the size of the silo body 1 can be comprehensively judged and then adaptively adjusted.
[0033] The coal bunker sump assembly includes a power source 1, a fluid source 2, a first pipe 3, a first valve, a platform 4, a connecting water pipe, a second pipe, and an anti-clogging unit. The power source 1 and the fluid source 2 are installed at the bottom of the outer wall of the bunker body 1, and the inlet of the connecting water pipe is connected to the fluid source 2 through the power source 1.
[0034] The power source 1 is preferably a water pump, and the fluid source 2 is preferably a fire water source. By turning on the water pump, water is transported through the connecting water pipe to the middle of the outer wall of the warehouse body 1.
[0035] A platform 4 is arranged around the middle of the outer wall of the warehouse body 1. A first pipe 3 is installed on the platform 4. The first pipe 3 is arranged around the middle of the outer wall of the warehouse body 1. The inlet of the first pipe 3 is connected to the outlet of the connecting water pipe. The outlet of the first pipe 3 is connected to the inlet of the second pipe. The outlet of the second pipe is arranged in a corresponding manner with the outlet. The outlet of the second pipe is connected to the middle of the warehouse cavity.
[0036] The arrangement of the outlet and outlet of the second pipe means that eight first through holes 12 are radially connected to the middle of the outer wall of the warehouse body 1, and one outlet corresponds to two first through holes 12. The two first through holes 12 are symmetrically arranged along the outlet. The first pipe 3 corresponding to the first through hole 12 is connected to the inlet of the second pipe. Taking the two second pipes corresponding to the first outlet 11a as an example, they are the second left pipe 4a1 and the second right pipe 4a2, and so on for the other second pipes. The outlet of the second pipe passes through the corresponding first through hole 12 and extends into the warehouse cavity.
[0037] In practical applications, one outlet is not limited to corresponding to two first through holes 12. It can be increased accordingly based on the situation of the saturation. The more outlets are added, the larger the saturation coverage area will be.
[0038] Platform 4 is also equipped with an anti-blocking unit, which is arranged in a corresponding manner with the outlet, and the outlet of the anti-blocking unit is connected to the middle of the cavity.
[0039] The anti-blocking unit is preferably an air cannon. Its working principle is to output a strong airflow so that the coal falls from the inner wall of the warehouse body 1 into the outlet. The anti-blocking unit is arranged in a corresponding manner with the outlet. This means that four anti-blocking units are set on the platform 4. One anti-blocking unit is set between adjacent first through holes 12, and a second through hole 13 is radially penetrated through the warehouse body 1 between adjacent first through holes 12. The second through hole 13 is arranged in a one-to-one correspondence with the anti-blocking unit. The outlet of the anti-blocking unit passes through the second through hole 13 and communicates with the warehouse cavity.
[0040] Based on actual working conditions, the number of anti-blocking units and second through holes 13 is not limited to four, as long as they correspond one-to-one and the positions of the second through holes 13 are staggered.
[0041] The second pipeline is equipped with a first valve, which can be opened and closed independently. Therefore, when the first outlet 11a needs to be filled, only the first valve corresponding to the first outlet 11a needs to be opened. This design not only ensures sufficient filling but also achieves centralized and precise filling, achieving two goals at once.
[0042] The usage process of this coal bunker soaking component is as follows:
[0043] First, the anti-blocking unit is activated, which outputs a strong airflow to cause coal to fall from the inner wall of the warehouse body 1 into the outlet.
[0044] Secondly, start the power source so that the fluid source enters the first pipe 3 through the connecting water pipe, and then open the first valve on the second pipe corresponding to the position where the soaking is needed to carry out the soaking.
[0045] Example 2
[0046] This embodiment requires protection of an automated coal sump system, using the coal sump assembly from Embodiment 1, including a control unit, preferably a control box, with the preferred model being JXF3001DS-06. The first valve is preferably a solenoid valve, with the preferred model being DF10-3 / 4-24Z, and the control unit can control the opening and closing of the solenoid valve.
[0047] The control box includes a main circuit, the main circuit input is connected to the power supply live wire L, and the main circuit is equipped with a main circuit breaker ql that is normally closed.
[0048] The control box also includes eight control circuits, each corresponding one-to-one with one of the eight solenoid valves. Each control circuit includes a circuit breaker QL, a fuse FU, a normally closed contact of a stop button SS, a normally open contact of a start button SF, a relay KA, a normally closed contact of a solenoid valve HY, and a running indicator light HL. (See also...) Figure 3Taking the first control circuit controlling the first solenoid valve HY1 as an example, the main circuit output is connected to the input of the first circuit breaker QL1. The output of the first circuit breaker QL1 is connected in series with the first fuse FU1 and the normally closed contact of the first stop button SS1. The output of the normally closed contact of the first stop button SS1 is simultaneously connected in parallel to the input of the normally open contact of the first start button SF1 and the input of the normally open auxiliary contact of the first relay KA1. The output of the normally open contact of the first start button SF1 and the output of the normally open auxiliary contact of the first relay KA1 are connected in parallel and then connected in series with the normally closed contact of the first solenoid valve HY1 and the first relay KA1. The first running indicator light HL1 is connected in parallel across the two ends of the first relay KA1. The output of the first relay KA1 is connected to the neutral line N of the power supply. Since the control circuit structure is the same, the control circuits of the remaining solenoid valves are similar and will not be described in detail. The second to seventh control circuits are simplified in the drawings.
[0049] The automated soaking system operates as follows:
[0050] The control box can control eight solenoid valves to work simultaneously or individually. When the control is working simultaneously, the main circuit breaker ql is used to connect or disconnect the control power supply.
[0051] When the control operates independently, taking the first control circuit controlling the first solenoid valve HY1 as an example, the circuit breaker QL1 is in the normally closed state. Pressing the start button SF1 closes the contacts of the first relay KA1, energizing the first solenoid valve HY1 and starting it to work, and the first running indicator light HL1 illuminates. Pressing the first stop button SS1 disconnects the first control circuit, opening the contacts of the first relay KA1, de-energizing the first solenoid valve HY1 and stopping it from working, and the first running indicator light HL1 goes out.
[0052] The start button SF automatically controls the corresponding solenoid valve HY to fill the tank, and the corresponding indicator light HL provides indication.
[0053] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
