Description

Technical Field

[0001] This utility model belongs to the technical field of metering pump trucks, and in particular relates to a metering pump truck. Background Technology

[0002] Metering pump trucks are a type of specialized slurry conveying equipment that works by measuring slurry during the conveying process. They are also widely used in coal mines to assist in processing and coal-water-slag separation, and to better support processing or construction. However, when flushing the pipes after work, it is inconvenient to observe the flushing status of the internal pipes. This can easily lead to slurry residue remaining in the pipes, which can solidify and cause blockages. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a metering pump truck that enables sampling and observation during the flushing process, making it easier to know the flushing status and avoiding the problem of residual slurry solidifying and causing blockage.

[0004] The technical solution is as follows: A metering pump truck includes a base, with a control cabinet and a distribution box bolted to both the front and rear sides of the upper left side of the base; a slurry pump is bolted to the right side inside the base; a three-way ball valve is connected to the slurry pump via a pipeline; a three-way fitting is connected to the flange at the left end of the three-way ball valve; a two-way ball valve is connected to the flange at the left end of the three-way fitting; a concentration meter is connected to the pipeline at the lower end of the three-way ball valve; a flow meter is connected to the pipeline at the left end of the concentration meter; a sampling and observation tube structure is provided above the base, characterized in that the sampling and observation tube structure includes a connecting shell, a limiting frame is bolted to the left side of the inner wall of the connecting shell; a working electric cylinder is bolted to the right end of the connecting shell; a sealing plug plate is bolted to the output shaft of the working electric cylinder; and a lower sampling and observation tank structure is located inside the connecting shell.

[0005] Preferably, the connecting shells are all fixed on the pipe between the slurry pump and the three-way ball valve, on the pipe through which the flow meter discharges slurry, and on the pipe through which the left end of the two-way ball valve supplies water to the tank seat.

[0006] Compared with the prior art, the beneficial effects of the present invention are:

[0007] This device allows for sampling and observation during the rinsing process, facilitating understanding of the rinsing status and preventing the solidification of residual slurry that could cause blockages.

[0008] In this invention, the connecting shell and the limiting frame are designed to work in conjunction with other structural connections.

[0009] In this invention, the working electric cylinder and the sealing plug plate are used to block and seal the connecting shell. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings: Example

[0016] As attached Figure 1 As shown, a metering pump truck includes a base 1. A control cabinet 3 and a power distribution box 2 are bolted to both the front and rear sections on the upper left side of the base 1. A slurry pump 4 is bolted to the right side inside the base 1. A three-way ball valve 5 is connected to the slurry pump 4 via a pipeline. A three-way fitting 6 is connected to the flange at the left end of the three-way ball valve 5. A two-way ball valve 7 is connected to the flange at the left end of the three-way ball valve 6. A concentration meter 8 is connected to the pipeline at the lower end of the three-way ball valve 5. A flow meter 9 is connected to the pipeline at the left end of the concentration meter 8. A sampling and observation tube structure 10 is installed above the base 1.

[0017] As attached Figure 2 As shown in the above embodiment, specifically, the sampling and observation tube structure 10 includes a connecting shell 101, a limiting frame 102 is bolted to the left side of the inner wall of the connecting shell 101; a working electric cylinder 103 is bolted to the right end of the connecting shell 101; a sealing plug plate 104 is bolted to the output shaft of the working electric cylinder 103; a lower sampling and observation tank structure 105 is located inside the connecting shell 101; the working electric cylinder 103 is driven to move the sealing plug plate 104 to expose the opening of the disassembly and assembly ring 1052.

[0018] As attached Figure 3 As shown in the above embodiment, specifically, the collection and observation tank structure 105 includes a tank body 1051, and a disassembly ring 1052 is integrally provided at the upper end of the tank body 1051; a sealing ring 1053 is sleeved on the outside of the disassembly ring 1052; the tank body 1051 is rotated in conjunction with the disassembly ring 1052 to realize the installation or disassembly for use.

[0019] In the above embodiments, specifically, the connecting shell 101 is fixed on the pipeline between the slurry pump 4 and the three-way ball valve 5, on the pipeline through which the flow meter 9 discharges slurry, and on the pipeline through which the left end of the two-way ball valve 7 supplies water to the tank seat 1.

[0020] The sealing plug plate 104 on the output shaft of the working electric cylinder 103 is adapted to the connecting shell 101, and the sealing plug plate 104 is made of rubber.

[0021] The limiting frame 102 is installed inside the connecting shell 101 and corresponds to the sealing plug 104, thereby restricting the movement of the movable sealing plug 104 and preventing it from shifting and affecting the sealing effect.

[0022] The tank 1051 is made of tempered glass, and the upper disassembly ring 1052 is threaded to the lower side inside the connecting shell 101, which facilitates the collection of water after rinsing to observe the rinsing situation and avoids the problem of residual slurry solidifying and causing blockage.

[0023] The sealing ring 1053 between the tank body 1051 and the connecting shell 101 is a rubber ring, which is used for sealing after the tank body 1051 is installed.

[0024] The working principle of this utility model is as follows: When metering and discharging slurry, the slurry pump 4 works to draw slurry from the tank 1 and delivers it to the concentration meter 8 through the three-way ball valve 5. After passing through the flow meter 9, it is discharged to complete the metering and discharge work. During the use of water replenishment and flushing, the three-way fitting 6 is connected to the pipeline for injecting clean water to transport water. Then, the three-way ball valve 5 and the two-way ball valve 7 are opened. In this way, water is injected into the tank 1 through the two-way ball valve 7 to replenish water and also enters the pipeline connected to the slurry pump 4, the concentration meter 8 and the flow meter 9 for flushing. During the flushing process, the working electric cylinder 103 is driven to move the sealing plug plate 104 to expose the opening of the disassembly ring 1052. In this way, water enters the tank 1051 from the working electric cylinder 103 to observe the water condition and judge the flushing status to complete the flushing work.

[0025] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution of this utility model, falls within the protection scope of this utility model.
