Description

Technical Field

[0001] This utility model relates to the field of suction and discharge vehicle technology, specifically to a fluidized bed purging device for a suction and discharge vehicle. Background Technology

[0002] Fluidized bed is a key component in pneumatic conveying systems for powder and granular materials. It is widely used in suction and discharge vehicles (suction and pressure conveying vehicles) and is mainly used for fluidized material conveying to improve loading and unloading efficiency. It is particularly suitable for the collection and transfer of powdery or granular materials such as dust, cement, mineral powder, and coke powder.

[0003] When the suction and discharge trucks or pressure discharge tank trucks used in the market are used to discharge materials with poor flowability and stickiness, the original bottom fluidized bed effect is limited, which causes the material to flow slowly or not at all after being lifted, resulting in difficulty in discharge and a sharp increase in the residual material rate. Utility Model Content

[0004] Therefore, this utility model provides a fluidized bed purging device for suction and discharge vehicles to solve the problems existing in the above-mentioned technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A fluidized bed purging device for suction and discharge vehicles, comprising:

[0007] The jetting pipe is installed through the side wall of the tank body and is located near the tail discharge port of the tank body. One end of the jetting pipe outside the tank body is connected to the air source. An air inlet valve and a pressure gauge are installed on the side of the jetting pipe outside the tank body. The pressure gauge is used to detect the gas pressure in the pipe.

[0008] The nozzle is connected to one end of the spray pipe located inside the tank, and the spray direction of the nozzle is set towards the tail of the tank, and the angle between the nozzle and the fluidized bed is an acute angle. The spray range of the nozzle at least completely covers the width direction of the fluidized bed.

[0009] Optionally, one end of the injection pipe located outside the tank is connected to a pressure-resistant pipe, the pressure-resistant pipe is connected to an air source, and the air inlet valve is located on the pressure-resistant pipe.

[0010] Optionally, the pressure-resistant pipe is made of flexible hose.

[0011] Optionally, the air source is an air compressor.

[0012] Optionally, it also includes a support frame, which is disposed on the inner wall of the tank. One end of the support frame is fixedly connected to the injection pipe, and the other end of the support frame is fixedly connected to the side wall of the tank.

[0013] Optionally, the tank body is also provided with two side slides, which are inclinedly arranged on both sides of the fluidized bed. The bottom of the side slides is attached to one side of the fluidized bed, and the top of the side slides is attached to the inner wall of the tank body.

[0014] Optionally, the injection pipe is located at 1 / 3 to 1 / 2 of the tank body near the tail end.

[0015] Optionally, multiple jet pipes and nozzles are provided at intervals along the length of the fluidized bed.

[0016] This utility model has at least the following beneficial effects:

[0017] This invention utilizes a spray pipe installed on the side wall of the tank, which is connected to a nozzle inclined towards the fluidized bed. This allows the nozzle to flush the fluidized bed towards the tail of the tank, blowing the material on the fluidized bed at the tail towards the discharge port. As a result, when the tank is lifted, the material at the front of the tank can flow towards the tail, improving discharge efficiency and reducing the residual material rate.

[0027] like Figure 1 and Figure 2 As shown, this utility model discloses a fluidized bed purging device for suction and discharge vehicles, comprising:

[0028] A jetting pipe 1 is installed through the side wall of the tank body 2 and is located near the tail discharge port of the tank body 2. One end of the jetting pipe 1 outside the tank body 2 is connected to a gas source. An air inlet valve 3 and a pressure gauge 4 are installed on the side of the jetting pipe 1 outside the tank body 2. The pressure gauge 4 is used to detect the gas pressure in the pipe.

[0029] Nozzle 5 is connected to one end of the spray pipe 1 placed inside the tank 2, and the spray direction of nozzle 5 is set towards the tail of the tank, and the angle between nozzle 5 and the fluidized bed is an acute angle. The spray range of nozzle 5 at least completely covers the width direction of the fluidized bed.

[0030] In this embodiment, the aforementioned spray pipe 1 is made of a high-strength material, such as stainless steel or metal pipe. The spray pipe 1 penetrates into the interior of the tank 2 through the side wall of the tank 2, and a sealing ring is provided between the outer wall of the spray pipe 1 and the tank 2 to seal the spray pipe 1 and the tank 2 and prevent material leakage from the tank 2. A nozzle 5 is provided at one end of the spray pipe 1 inside the tank 2. The nozzle 5 is connected to the spray pipe 1. The nozzle 5 adopts a flat structure so that the spray range of the nozzle 5 can at least completely cover the width direction of the fluidized bed. The nozzle 5 is tilted towards the tail of the tank, and the angle between the spray direction of the nozzle 5 and the fluidized bed is set to an acute angle to ensure that the nozzle 5 can blow the material adhering to the fluidized bed toward the rear of the tank 2. At the same time, the spray pipe 1 is located at 1 / 3-1 / 2 of the tank 2 near the tail of the tank, and the nozzle 5 is located near the discharge port at the tail of the tank 2 to facilitate the material being blown to the discharge port for discharge.

[0031] It should be noted that the angle between the nozzle 5 and the fluidized bed can be set according to actual needs, which will not be elaborated here.

[0032] In one specific embodiment, the end of the blowing pipe 1 located outside the tank body 2 is connected to a pressure-resistant pipe 6, the pressure-resistant pipe 6 is connected to an air source, and the air inlet valve 3 is installed on the pressure-resistant pipe 6.

[0033] The aforementioned spray pipe 1 is connected to an air source outside the tank 2. Specifically, it is connected to the spray pipe 1 at one end and the air source at the other end through a flexible pressure-resistant pipe 6. The air source is generally an air compressor. The air is compressed by the air compressor and then transported to the nozzle 5 through the pipe before being sprayed out.

[0034] In a further embodiment, a support frame 7 is also included, which is disposed on the inner wall of the tank body 2. One end of the support frame 7 is fixedly connected to the injection pipe 1, and the other end of the support frame 7 is fixedly connected to the side wall of the tank body 2.

[0035] A rigid support frame 7 is installed inside the tank body 2. One end of the support frame 7 is fixed to the bottom of the injection pipe 1, and the other end of the support frame 7 is fixedly connected to the side wall of the tank body 2 (at least twice in the fluidized bed to avoid affecting the flow of materials on the fluidized bed). The support frame 7 is generally made of metal, but it can also be set according to the materials stored inside the tank body 2, such as anti-corrosion materials.

[0036] In a further embodiment, the tank body 2 is also provided with two side slide plates 8. The two side slide plates 8 are inclinedly arranged on both sides of the fluidized bed. The bottom of the side slide plate 8 is attached to one side of the fluidized bed, and the top of the side slide plate 8 is attached to the inner wall of the tank body 2.

[0037] By setting side slides 8 on both sides of the fluidized bed, the material flow on both sides can be easily gathered on the fluidized bed and purged by nozzles 5.

[0038] It should be noted that for a long tank 2, multiple blowing pipes 1 and nozzles 5 can be installed inside the tank 2 to continuously blow the material on the fluidized bed toward the discharge port.

[0039] The setup in this application does not affect the performance of the original fluidized bed inside the tank; the newly added purging device can blow the material backward when it encounters poor material flowability or stickiness, effectively improving the discharge efficiency; the structure is simple and multiple purging devices can be configured as needed, which can continuously blow the material backward and adapt to longer tanks 2.

[0040] Working principle: When encountering materials with poor flowability and stickiness, observe the pressure gauge 4. When the compressed air reaches the purging pressure, open the air inlet valve 3. The compressed air passes through the pressure-resistant pipe 6 and the spray pipe 1, and continuously purifies the surface of the fluidized bed through the nozzle 5 (flat type) tilted downward at a certain angle. This blows the materials with poor flowability and stickiness to the tail discharge port, allowing the materials to be discharged smoothly.

[0041] The above specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0042] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0043] The present invention has been described in a relatively specific and detailed manner above through general description and specific embodiments. It should be noted that, without departing from the concept of the present invention, various modifications and improvements can be made to these specific embodiments, all of which fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
