Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ore pulp conveying, in particular to a sink stone valve. BACKGROUND

[0002] Ore pulp is a solid ore resource containing potassium, sodium and magnesium ions. The ore pulp in the evaporation pond is excavated by a mining ship and is conveyed to a processing workshop through a pipeline. After ore dressing and halogen removal in the processing workshop, a high-purity potassium fertilizer product is obtained. In the conveying process of the ore pulp, the conveying amount of the ore pulp directly affects the yield of the potassium fertilizer product. Therefore, it is necessary to increase the conveying amount of the ore pulp to ensure the production amount of the potassium fertilizer product.

[0003] In the prior art, a sink stone valve and a centrifugal pump are usually used to transport ore pulp. The centrifugal pump is arranged downstream of the sink stone valve. An electric gate valve is arranged on the sink stone valve. The electric gate valve comprises a driving member and a moving member. The moving member is movably arranged in the valve body. The driving member is used to drive the moving member to move. When the moving member is located in the valve body, the moving member divides the sink stone valve into two chambers, i.e., an upper material conveying chamber and a lower impurity removing chamber. The material conveying chamber is used to convey the ore pulp, and the impurity removing chamber is used to remove impurities. When the moving member extends out of the valve body, the material conveying chamber and the impurity removing chamber are in communication. The working principle of the sink stone valve is as follows: the ore pulp enters the valve body through the feeding pipe. Under the action of the filter plate, the liquid in the ore pulp is discharged through the discharge pipe and is transported by the centrifugal pump. The solid in the ore pulp remains in the material conveying chamber of the valve body. When the flow meter arranged at the discharge pipe detects that the flow at the discharge pipe decreases to a certain specific value, the flow meter sends a signal to the controller. The controller drives the driving member. The driving member drives the moving member arranged in the valve body to move. The moving member extends out of the valve body to change the material conveying chamber and the impurity removing chamber from the separated state to the connected state. The solid in the ore pulp falls from the material conveying chamber into the impurity removing chamber. At this time, the flow of the flow meter returns to normal. The driving member drives the moving member to extend into the valve body to change the material conveying chamber and the impurity removing chamber from the connected state to the separated state. The solid in the ore pulp in the impurity removing chamber is manually removed. However, when the salt blocks and impurities fall into the impurity removing chamber, the entire chamber will have a cavity. In this way, the liquid cannot enter the centrifugal pump, and it is difficult to realize continuous feeding of the sink stone valve. SUMMARY

[0004] The main purpose of the utility model is to provide a sink stone valve to solve the problem that the sink stone valve in the prior art is difficult to continuously feed.

[0006] Further, the inlet of the second pipeline is located at one end of the impurity removal chamber close to the feed chamber, and the second pipeline extends upward along a second direction, the second direction being perpendicular to the first direction.

[0007] Further, the valve body is provided with a foreign matter discharge port, the plugging part further includes a hinge, including two connecting pieces and a rotating shaft, the two connecting pieces are rotatably connected with the rotating shaft, one of the two connecting pieces is connected with the valve body, the other of the two connecting pieces is connected with a first side of the plugging piece, the plugging piece is configured to be capable of sealingly cooperating with the foreign matter discharge port; a handle is connected with a second side of the plugging piece, the handle is provided with a locking piece, the locking piece is configured to be capable of lockingly cooperating with or being unlocked from the valve body.

[0008] Further, the filter part is a filter plate, a plurality of filter holes are provided on the filter plate; or, the filter part is a grating plate; the filter part is arranged perpendicularly to the first direction.

[0009] Further, the valve body has a first plane, the first plane is perpendicular to the first direction, the area of the orthographic projection of the filter plate on the first plane is equal to the flow area of the feed chamber.

[0010] Further, the filter part separates the feed chamber into a first chamber and a second chamber, the first chamber is arranged above the impurity removal chamber, the feed pipe, the first chamber, the second chamber and the discharge pipe are arranged in sequence.

[0011] Further, the cross-sectional areas of the first chamber, the second chamber and the discharge pipe decrease in sequence.

[0014] Furthermore, the sinker valve also includes a maintenance port, which is located at the top of the valve body and communicates with the first chamber.

[0015] Applying the technical solution of this utility model, the material enters the conveying chamber through the feed pipe. Under the action of the filter section, the solids (i.e., salt blocks and impurities) in the material remain in the conveying chamber, while the liquid in the material is discharged through the discharge pipe. When the accumulated salt blocks and impurities in the conveying chamber reach a certain amount, the driving component drives the moving component to move away from the filter section along the first direction, so that the conveying chamber and the impurity removal chamber change from a separated state to a connected state. In this way, the salt blocks and impurities in the material settle into the impurity removal chamber under the action of gravity. After the salt blocks and impurities have completely settled into the impurity removal chamber, the driving component drives the moving component again to move towards the filter section along the first direction, so that the conveying chamber and the impurity removal chamber change from a connected state to a separated state, opening the seal. A plug connects the impurity removal chamber to the outside. Salt blocks and impurities are manually discharged. After the plug is closed, liquid is introduced into the impurity removal chamber through the first pipe. Air in the impurity removal chamber is discharged through the second pipe. When liquid overflows from the second pipe, the impurity removal chamber is full of liquid, so that the impurity removal chamber can continue to receive material discharged from the conveying chamber. Compared with the prior art, in this embodiment, by setting the first and second pipes, the impurity removal chamber can always be filled with liquid. During the process of salt blocks and impurities settling into the impurity removal chamber, the phenomenon of cavity formation in the conveying chamber can be avoided. This can prevent cavitation of the centrifugal pump and avoid discontinuous material conveying, thereby improving the material transportation efficiency. Attached Figure Description

[0028] Specifically, in the embodiment of the utility model, the liquid introduced into the sundry removing chamber 13 from the first pipeline 6 is water.

[0029] Specifically, in the embodiment of the utility model, the material is ore pulp.

[0030] Specifically, in the embodiment of the utility model, the sediment valve further includes a flow monitoring component and a controller 11, the flow monitoring component is arranged at the discharge pipe 3, the controller 11 is arranged on the valve body 1, the flow monitoring component is a flowmeter, the flowmeter is used to detect the liquid flow at the discharge pipe 3, the flowmeter is in control connection with the controller 11, the controller 11 is in control connection with the driving part, when the flowmeter detects that the liquid flow of the discharge pipe 3 drops to a certain value (due to the accumulation of salt blocks and sundries in the material conveying chamber 12, the flow drops), the flowmeter gives a signal to the controller 11, the controller 11 controls the driving part, so that the driving part drives the moving part to move along the first direction, so that part of the moving part moves to the outside of the valve body 1 in the direction away from the discharge pipe 3, so that the material conveying chamber 12 and the sundries removing chamber 13 change from the separated state to the connected state; the salt blocks and sundries in the material conveying chamber 12 drop into the sundries removing chamber 13 under the action of gravity, and the material conveying chamber 12 normally conveys materials, when the liquid flow of the discharge pipe 3 recovers to the normal value, the driving part drives the moving part to move along the first direction, so that part of the moving part moves to the inside of the valve body 1 in the direction close to the discharge pipe 3, so that the material conveying chamber 12 and the sundries removing chamber 13 change from the connected state to the separated state, so that the material conveying chamber 12 can normally convey materials.

[0031] Specifically, in the embodiment of the utility model, when the flowmeter detects that the liquid flow of the discharge pipe 3 drops to a certain value, the material conveying chamber 12 and the sundries removing chamber 13 can change from the separated state to the connected state, wherein the certain value of the liquid flow is obtained by the staff according to experience; when the liquid flow of the discharge pipe 3 recovers to the normal value, the material conveying chamber 12 and the sundries removing chamber 13 can change from the connected state to the separated state, wherein the normal value of the liquid flow is also obtained by the staff according to experience, and the certain value of the liquid flow is less than the normal value of the liquid flow.

[0032] Specifically, in the embodiment of the utility model, the separation part 5 is an electric gate valve, the electric gate valve includes an electric actuator and a gate, the driving part is the electric actuator, and the moving part is the gate, the electric actuator includes a motor, a screw rod and a nut, the output end of the motor is connected with the screw rod, the nut is arranged on the outer periphery of the screw rod and is in screw connection with the screw rod, and the gate is connected with the nut, so that the rotation of the motor is converted into the movement of the gate, so that the gate moves along the first direction, and the specific structure of the electric gate valve can refer to the prior art, and details are not described herein.

[0033] Specifically, in the embodiment of the utility model, the electric gate valve further includes a frame, the frame is arranged on the outer periphery of the gate, and a sealing element is arranged between the gate and the frame, when the material conveying chamber 12 and the sundries removing chamber 13 are in the separated state, the gate can form close contact with the valve body 1, so that the leakage of the ore pulp through the gap between the material conveying chamber 12 and the sundries removing chamber 13 is avoided.

[0034] As Figures 1 to 5As shown in the embodiment of this utility model, the inlet of the second pipeline 10 is located at one end of the impurity removal chamber 13 near the material conveying chamber 12, and the second pipeline 10 extends upward along the second direction, which is perpendicular to the first direction.

[0035] In the above technical solution, compared with setting the second pipe 10 at the bottom of the impurity removal chamber 13, the phenomenon that the liquid injected into the impurity removal chamber 13 by the first pipe 6 is directly discharged from the impurity removal chamber 13 through the second pipe 10 can be avoided, thereby avoiding the phenomenon that it is difficult to expel air from the impurity removal chamber 13, so that the impurity removal chamber 13 can be filled with liquid.

[0036] like Figures 1 to 5 As shown in the embodiment of this utility model, the valve body 1 is provided with a discharge port, and the sealing part 4 also includes a hinge 41, which includes two connecting pieces and a rotating shaft. The two connecting pieces are rotatably connected to the rotating shaft, one of the two connecting pieces is connected to the valve body 1, and the other connecting piece is connected to the first side of the sealing member 42. The sealing member 42 is configured to seal with the discharge port. The handle 43 is connected to the second side of the sealing member 42, and the handle 43 is provided with a locking member. The locking member is configured to lock or unlock with the valve body 1.

[0037] In the above technical solution, on the one hand, the structure of the hinge 41 allows the sealing member 42 to open or close the discharge port by rotation. When it is necessary to clean the salt blocks and debris in the impurity removal chamber 13, the operator only needs to unlock the locking member and gently pull the handle 43 to open the sealing member 42 without any effort. This simplifies the cleaning process and improves work efficiency. On the other hand, the locking cooperation between the locking member and the valve body 1 can prevent the sealing member 42 from being accidentally opened due to the impact of the slurry, ensuring the safety of the operator.

[0038] Specifically, in the embodiments of this utility model, the locking element is a screw, and the valve body 1 is provided with a threaded hole. By locking the screw into the threaded hole, the handle 43 and the valve body 1 can be locked together.

[0039] like Figures 1 to 5 As shown in the embodiments of this utility model, the filter part 8 is a filter plate with a plurality of filter holes 81; or, the filter part 8 is a grid plate, and the filter part 8 is arranged perpendicular to the first direction.

[0040] In the above technical solution, on the one hand, since the filter section 8 is vertically arranged in the conveying chamber 12, under the action of gravity, the salt blocks and impurities in the slurry are more likely to fall along the surface of the filter section 8 into the conveying chamber 12; on the other hand, the multiple filter holes 81 can effectively intercept the salt blocks and impurities in the slurry, ensuring that the liquid in the slurry meets the transportation conditions and improving the purity of the slurry.

[0041] Specifically, the grid plate has high wear resistance and can withstand the scouring of salt blocks and impurities in the ore pulp.

[0042] As shown in Figures 1 to 5 the first plane is perpendicular to the first direction, and the orthogonal projection area of the filter plate on the first plane is equal to the flow area of the material conveying chamber.

[0043] In the above technical solution, since the orthogonal projection area of the filter plate is equal to the flow area, all ore pulp can be fully filtered during the conveying process, thereby effectively filtering salt blocks and impurities in the ore pulp and improving the filtering efficiency.

[0044] It should be noted that in the embodiment of the present application, the flow area refers to the cross-sectional area passed by the fluid when flowing in the material conveying chamber 12.

[0045] As shown in Figures 1 to 5 the filter plate divides the material conveying chamber 12 into a first chamber 121 and a second chamber 122, the first chamber 121 is arranged above the impurity removal chamber 13, and the feed pipe 2, the first chamber 121, the second chamber 122 and the discharge pipe 3 are arranged in sequence.

[0046] In the above technical solution, the filter plate is designed to divide the material conveying chamber 12 into two independent chambers, the first chamber 121 is used to accommodate salt blocks and impurities in the ore pulp; the liquid in the ore pulp can pass through the second chamber 122, so that the liquid in the ore pulp is discharged through the discharge pipe 3, thereby improving the filtering efficiency and separation effect of the ore pulp.

[0047] Specifically, in the embodiment of the present application, the first chamber 121 is arranged above the impurity removal chamber 13, and the gravity is used to make the salt blocks and impurities intercepted by the filter plate sink naturally to the lower impurity removal chamber 13, without the need for additional mechanical force or fluid power assistance, thereby reducing energy consumption and maintenance cost.

[0048] As shown in Figures 1 to 5 the cross-sectional area of the first chamber 121, the second chamber 122 and the discharge pipe 3 decreases in sequence.

[0049] In the above technical solution, since the cross-sectional area of the first chamber 121, the second chamber 122 and the discharge pipe 3 decreases in sequence, the flow rate of the ore pulp will gradually increase, so that the ore pulp can be prevented from directly entering the discharge pipe 3 through the valve body 1 with a larger flow area, thereby avoiding the sudden change of the flow rate of the ore pulp, and further avoiding the phenomenon of turbulent flow.

[0050] As shown in Figures 1 to 5As shown in the embodiment of the utility model, the sediment valve further comprises a third pipeline 7, which is arranged on the valve body 1 and communicates with the first chamber 121.

[0051] In the above technical solution, when it is necessary to detect whether the chamber leaks, the feed chamber 12 and the impurity removal chamber 13 change from the separated state to the communicated state, liquid is injected into the feed chamber 12 through the third pipeline 7, and when the liquid overflows from the second pipeline 10, the chamber is filled with liquid, which proves that the chamber does not leak.

[0052] As shown in the embodiment of the utility model, the inner diameter of the discharge pipe 3 gradually decreases from the first chamber 121 to the second chamber 122. Figures 1 to 5

[0053] Through the above arrangement, the flow rate of the ore slurry in the discharge pipe 3 gradually increases from the first chamber 121 to the second chamber 122, so that the conveying efficiency of the ore slurry can be improved.

[0054] Specifically, in the embodiment of the utility model, the minimum diameter of the discharge pipe 3 can effectively intercept any unfiltered salt blocks and impurities, reduce the risk of downstream equipment blockage, thereby reducing the probability of shutdown maintenance and improving the operation efficiency of the sediment valve.

[0055] As shown in the embodiment of the utility model, the sediment valve further comprises a maintenance hole 9, which is arranged at the top of the valve body 1 and communicates with the first chamber 121. ​

[0056] In the above technical solution, the maintenance hole 9 is located at the top of the valve body 1, which facilitates the technicians to check, clean and maintain the chamber without completely disassembling the sediment valve, reduces the difficulty and time cost of maintenance, and improves the maintenance efficiency of the equipment.

[0057] Specifically, the sediment valve provided by the utility model solves the problem that the centrifugal pump is easily blocked by salt blocks and impurities and needs to be stopped for maintenance, and also solves the problems of difficult pump opening and long pump stopping time, and has the advantages of simple structure, convenient operation, high work efficiency and good production efficiency.

[0058] ​​Specifically, in the embodiment of the utility model, the traditional sediment valve needs to stop running equipment in the cleaning process, and can start running the sediment valve again after cleaning is completed, because the time occupied by cleaning is long, the operation process is complex, and the completion of production task is seriously affected, and the equipment does not have the condition of continuous operation, in production, because the number of cleaning increases, the processing and conveying of ore slurry cannot be continuously and stably supplied according to the demand, the ore conveying amount is reduced, and the completion of the annual potash fertilizer production task is greatly affected. In view of the above problems of the traditional sediment valve, the sediment valve of the utility model can improve the operation efficiency of the ore conveying equipment, make it continuously run, improve the ore slurry conveying amount, and provide a favorable prerequisite for completing the annual potash fertilizer production amount. The original sediment valve is provided with an electric gate valve, the long cleaning time of stopping the pump is solved, the ore conveying equipment operation time and efficiency are improved, the ore slurry conveying amount is improved, the potash fertilizer production amount is increased, and the annual production task is facilitated to be completed.

[0059] From the above description, it can be seen that the embodiment of the utility model realizes the following technical effects: the material enters the material conveying chamber through the feeding pipe, under the action of the filtering part, the solid (i.e. salt block and impurities) in the material remains in the material conveying chamber, and the liquid in the material is discharged through the discharging pipe; when the salt block and impurities accumulated in the material conveying chamber reach a certain amount, the driving part drives the moving part to move in the first direction away from the filtering part, so that the material conveying chamber and the impurity removal chamber change from the separated state to the connected state; in this way, the salt block and impurities in the material sink to the impurity removal chamber under the action of gravity; after the salt block and impurities completely sink to the impurity removal chamber, the driving part drives the moving part again, so that the moving part moves in the first direction towards the filtering part, so that the material conveying chamber and the impurity removal chamber change from the connected state to the separated state; the sealing part is opened, so that the impurity removal chamber is connected with the outside, the salt block and impurities are discharged by manual operation, the sealing part is closed, and the liquid is introduced into the impurity removal chamber through the first pipeline; the air in the impurity removal chamber is discharged through the second pipeline; when the liquid overflows from the second pipeline, the impurity removal chamber has been filled with liquid, so as to continuously receive the material discharged from the material conveying chamber in the subsequent impurity removal chamber; compared with the prior art, in the embodiment, the first pipeline and the second pipeline are arranged, so that the impurity removal chamber is always filled with liquid; in the process of sinking the salt block and impurities to the impurity removal chamber, the phenomenon of cavity in the material conveying chamber can be avoided; in this way, the phenomenon of cavitation of the centrifugal pump can be avoided, so as to avoid the phenomenon of discontinuous material conveying, thereby improving the transportation efficiency of the material.
