Existing powdery material tank trucks have the following shortcomings in use:

[0003] 1. When unloading materials from tank trucks after they arrive at the factory, there is a lack of an auxiliary mechanism to pressurize the inside of the tank for rapid material discharge. The powder and granular materials have poor flowability and are difficult to discharge smoothly and quickly, resulting in poor discharge efficiency. 2. There is a lack of an auxiliary mechanism for personnel to clean the inside of the tank. After entering through the manhole, it is difficult for personnel to quickly clean the inside. In view of this, this application proposes a powder tank with a pressurization device to solve the above-mentioned problems. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1

[0037] like Figures 1 to 2 As shown, this embodiment proposes a powder tank with a pressurizing device, including a powder tank body 1 installed on a transport vehicle. Multiple manholes are fixedly connected to the top of the powder tank body 1, and caps are fixedly installed on the manholes by multiple bolts. A pressurizing device body is installed on the powder tank body 1. By installing the pressurizing device body on the powder tank body 1, convenience is provided to the user. The pressurizing device body includes:

[0038] Triangular fixing bracket 2 is fixedly connected to the bottom left side of the powder tank body 1;

[0039] Air compressor 201 is fixedly installed inside the triangular fixed bracket 2. A condenser is fixedly installed inside the triangular fixed bracket 2. The air inlet of the condenser and the air outlet of the air compressor 201 are connected and fixed through a pipe.

[0040] The oil-water separator 202 has its air inlet connected and fixed to the condenser outlet via a pipe. Its outlet is connected and fixed to a bend 203. One end of the bend 203 is connected and fixed to a horizontal pipe 204. The end of the horizontal pipe 204 away from the bend 203 is sealed. Multiple spare air injection valves 205 are connected and fixed to the bottom of the horizontal pipe 204. The horizontal pipe 204 is fixedly installed on the bottom left side of the powder tank body 1. An air injection pipe 206 is connected and fixed to the top left side of the horizontal pipe 204. One end of the air injection pipe 206 is connected and fixed to the top left side of the powder tank body 1. Multiple clamps, all fixedly connected to the outside of the air injection pipe 206, are fixedly fitted onto the outside of the air injection pipe 206, providing support and fixation. The air compressor 201 is used for subsequent transportation to the work site. After the plant connects to the power supply at the factory site, it compresses and supplies compressed gas. The condenser is used to cool the supplied compressed gas and send it to the oil-water separator 202, which can prevent the high-temperature gas from having an adverse effect on the material. The oil-water separator 202 is used to separate the moisture in the gas, which can prevent the moisture in the gas from affecting the dryness of the material. The gas is then supplied to the horizontal pipe 204 through the bend pipe 203, and then supplied to the powder tank body 1 through the air injection pipe 206 to pressurize the inside, so as to assist the rapid discharge of the powder or granular material inside. The spare air injection valve 205 is set up to allow personnel to connect to an external independent high-pressure gas equipment for further pressurization when the pressure of the gas supplied by the air compressor 201 is still insufficient.

[0041] This embodiment can pressurize the inside of the powder tank body 1 to assist in rapid material discharge, reduce the phenomenon that the powder material is difficult to discharge smoothly and quickly due to its poor flowability, and improve the discharge efficiency.

[0042] It should be noted that the method of fixing the manhole cover with multiple bolts is an existing technology and has extremely wide application in the field of cover installation.

[0043] The usage method of this embodiment is as follows: When the powder tank with pressurization device is transported to the factory and its discharge port is opened for unloading, the power cord of the electrical equipment of this device is connected to the factory power supply facility for power supply. When the air compressor 201 is turned on, compressed gas is compressed and supplied to the condenser. The condenser cools the supplied compressed gas and supplies it to the oil-water separator 202. The oil-water separator 202 separates the moisture in the gas and supplies the gas through the bend pipe 203 into the horizontal pipe 204. The gas is then supplied into the powder tank body 1 through the air injection pipe 206 to pressurize the inside, so as to assist the rapid discharge of powder or granular materials inside. The spare air injection valve 205 is provided so that when the pressure of the gas supplied by the air compressor 201 is still insufficient, personnel can connect to an external independent high-pressure gas device through an external pipeline to further pressurize the gas, thereby achieving the effect of pressurizing the inside of the powder tank body 1 to assist in rapid discharge, reducing the phenomenon that the powder and granular materials are difficult to discharge smoothly and quickly due to poor flowability, and improving the discharge efficiency.

[0044] Example 2

[0045] like Figure 3 As shown, this embodiment differs from Embodiment 1 in that: the rear of the transport vehicle and the rear of the powder tank body 1 are fixedly connected to the same ladder 101; the transport vehicle is equipped with a pressure tank 3 for supplying air to the air brakes; the ladder 101 consists of two side pipes and multiple foot levers fixedly connected between the two side pipes; a first flexible air tube 301 is fixedly connected to the outside of the pressure tank 3; one end of the first flexible air tube 301 movably passes through one of the side pipes and is fixedly connected to a squeeze-type air gun. 302; The pressure tank 3, the first flexible air hose 301, and the pinch-blow air gun 302 are configured in conjunction. Since the tank transport vehicles are all air brake type special transport vehicles, they have their own pressure tank 3 for supplying air to the air brakes. After the subsequent material discharge, when the personnel unseal and open the manhole, the personnel can use the pinch-blow air gun 302 to blow away the residual granular material adhering to the inside of the powder tank body 1, thereby reducing the waste of a large amount of residual material or affecting the subsequent storage of other powder materials in the powder tank body 1, and improving the subsequent internal cleanliness.

[0046] This embodiment can assist personnel in quickly blowing away and cleaning powder particles adhering to the powder tank body 1, reducing the difficulty of quickly cleaning the interior by conventional wiping after personnel enter through the manhole, and improving the efficiency of subsequent internal cleaning.

[0047] It should be noted that the two side pipes in the ladder 101 are fixedly installed at the rear of the transport vehicle and the rear of the powder tank body 1.

[0048] The usage method of this embodiment is as follows: Since the tank carriers are all air-brake type special-purpose transport vehicles, they have their own air pressure tanks 3 for supplying air to the air brakes. After the subsequent material discharge, when the personnel unseal and open the manhole, the personnel squeeze and open the squeeze-blowing air gun 302, so that the high-pressure gas in the air pressure tank 3 is blown out sequentially through the first soft air tube 301 and the squeeze-blowing air gun 302. The personnel can use the squeeze-blowing air gun 302 to blow away the residual particles adhering to the inside of the powder tank body 1, thereby achieving the effect of quickly blowing away the powder particles adhering to the inside of the powder tank body 1, reducing the phenomenon that it is difficult to quickly clean the inside by conventional wiping after the personnel enter through the manhole, and improving the efficiency of subsequent internal cleaning.

[0049] Example 3

[0050] like Figures 4 to 6 As shown, this embodiment differs from Embodiment 2 in that: an arrangement-type winding and releasing mechanism 4 is provided between one end of the first flexible air tube 301 and the air inlet of the pinch-and-blow air gun 302. The arrangement-type winding and releasing mechanism 4 includes:

[0051] U-shaped support 401 is fixedly connected to the top of the powder tank body 1;

[0052] The fixed box 402 has openings on its rear side and bottom, and is fixedly connected to the inner wall of the rear side and the inner wall of the bottom of the U-shaped support 401, respectively.

[0053] The rotating shaft 405 is rotatably fitted into the front side of the fixed box 402; wherein the front side of the fixed box 402 has a first round hole, and a first bearing is fixedly fitted in the first round hole. The inner ring of the first bearing is fixedly fitted with the outer side of the rotating shaft 405, so as to achieve the effect of rotating the rotating shaft 405.

[0054] The winding drum 403 has a hollow structure and is fixedly connected to the front end of the rotating shaft 405;

[0055] The connecting pipe 404 is rotatably and sealed in the middle of the front side of the take-up drum 403 and is connected and fixed to one end of the first flexible air tube 301. The U-shaped support 401 is fixedly sleeved on the connecting pipe 404. A circular through hole is opened in the middle of the front side of the take-up drum 403, and two sealed bearings are fixedly sleeved in the circular through hole. The inner ring of the sealed bearing is fixedly sleeved with the outer side of the connecting pipe 404, so as to achieve the effect of sealing and rotating the take-up drum 403 from the inside. The front side of the U-shaped support 401 has a sleeve hole that is fixedly connected to the outer side of the connecting pipe 404, so as to fix and support the connecting pipe 404.

[0056] The second flexible air tube 412 is wound around the outside of the take-up drum 403. One end of it is connected and fixed to the front side of the top of the take-up drum 403, and the other end is connected and fixed to the air inlet of the pinch-blowing air gun 302.

[0057] The linkage rotary drive assembly is housed in the fixed box 402 and is fixedly connected to the rear end of the rotating shaft 405;

[0058] The reciprocating horizontal guide drive assembly is installed between the inner front wall of the U-shaped support 401 and the inner front wall of the fixed box 402, and is fixedly connected to the linkage rotary drive assembly. A guide sleeve 413 is fixedly connected to its top, and the guide sleeve 413 is movably sleeved on the second soft air tube 412. The linkage rotary drive assembly is used to drive the rotating shaft 405 and the reciprocating horizontal guide drive assembly to rotate. The rotation of the rotating shaft 405 drives the winding drum 403 to rotate to release or wind up the second soft air tube 412. The reciprocating horizontal guide drive assembly is used to drive the guide sleeve 413 to reciprocate laterally when rotating. The reciprocating motion of the guide sleeve 413 achieves the effect of reciprocating motion to arrange the second soft air tube 412 when it is wound up, avoiding the phenomenon that the second soft air tube 412 is easy to slip and scatter when piled up in one position.

[0059] Furthermore, such as Figure 6 As shown, the linkage rotary drive assembly includes a first gear 406, a second gear 407 and a brake motor 411 disposed inside the fixed box 402. The first gear 406 is fixedly connected to the rear end of the rotating shaft 405. The second gear 407 meshes with the bottom of the first gear 406. The brake motor 411 is fixedly installed on the rear side of the U-shaped support 401. The output shaft of the brake motor 411 is fixedly connected to the rear side of the first gear 406.

[0060] In this embodiment, the first gear 406, the second gear 407 and the brake motor 411 cooperate to drive the first gear 406 to rotate. The first gear 406 drives the rotating shaft 405 and the second gear 407 to rotate. The rotation of the rotating shaft 405 drives the winding drum 403 to rotate to release or wind up the second flexible air tube 412.

[0061] Furthermore, such as Figure 6 As shown, the reciprocating transverse guide drive assembly includes a reciprocating lead screw 408, a slider 410, and two transverse guide rods 409. The reciprocating lead screw 408 is rotatably mounted between the front inner wall of the U-shaped support 401 and the front inner wall of the fixed box 402. The two transverse guide rods 409 are fixedly connected between the front inner wall of the U-shaped support 401 and the front side of the fixed box 402. The slider 410 is slidably sleeved on the two transverse guide rods 409. The front side of the slider 410 has a reciprocating thread hole that is threadedly connected to the reciprocating lead screw 408. The rear end of the reciprocating lead screw 408 is fixedly connected to the front middle part of the second gear 407. The slider 410 is also fixedly connected to the guide sleeve 413.

[0062] In this embodiment, a second circular hole is provided at the bottom front side of the fixed box 402. A second bearing is fixedly connected to both the second circular hole and the inner wall of the front side of the U-shaped support 401. The inner ring of the second bearing is fixedly connected to the outer side of the reciprocating screw 408, which serves to rotate the reciprocating screw 408. The rear side of the slider 410 has two horizontal guide holes that are respectively slidably fitted to the outer side of the corresponding horizontal guide rod 409, which serve to guide the slider 410 laterally.

[0063] It should be noted that a wireless remote control switch is fixedly installed on the outside of the brake motor 411. The wireless remote control switch is connected to the brake motor 411 via a flexible wire. The wireless remote control switch preferably adopts the CE31-BxxR series remote control switch, which has the advantage of high remote control sensitivity within a certain distance, meeting the requirements of non-long-distance remote control. In terms of power supply, since the powder unloading site is a factory area with sufficient on-site power supply facilities, the power cord of the electrical equipment of this device can be connected to the factory power supply facilities for power supply.

[0064] This embodiment allows the second flexible tube 412 to be released during use to provide conditions for pulling and adjusting the blowing position; and after use, the second flexible tube 412 can be rolled up and reciprocated to arrange it in a unified manner, avoiding the phenomenon that the second flexible tube 412 is easy to slip and scatter in one position, thus improving the neatness after use; and by rolling it up, the phenomenon that the upper part of the second flexible tube 412 is scattered and exposed to the outside, affecting subsequent use, thus improving the neatness of the upper part.

[0065] The usage method of this embodiment is as follows: Based on Embodiment 2, the difference is that a shorter first flexible air tube 301 can be used to avoid its long and messy appearance at the top. When it needs to be extended, the operator starts the brake motor 411 in the forward direction, which drives the first gear 406 to rotate. The first gear 406 drives the rotating shaft 405 and the second gear 407 to rotate. The rotating shaft 405 drives the winding drum 403 to rotate and release the second flexible air tube 412. When the second gear 407 rotates, it drives the reciprocating screw 408 to rotate. The rotation of the reciprocating screw 408 drives the slider 410 to slide back and forth laterally on the two horizontal guide rods 409. The slider 410 drives the guide sleeve 413 to move back and forth laterally. The reciprocating movement of the guide sleeve 413 drives the lower part of the second flexible air tube 412 to move back and forth laterally, performing a staggered release operation. When squeezed open, the gas passes sequentially through the first flexible air tube 301, the connecting tube 404, the winding drum 403, and... The second flexible air tube 412 is fed into the pinch-blow air gun 302 and then blown out. After the operator turns it on, they pull the pinch-blow air gun 302 to move it to the position inside the powder tank body 1 that needs to be cleaned. After use, the operator starts the brake motor 411 in the reverse direction, which is completely opposite to the direction of movement of the brake motor 411 started in the forward direction. At this time, the winding drum 403 turns to rotate and winds up the second flexible air tube 412. At this time, the guide sleeve 413 moves back and forth laterally again. The reciprocating movement of the guide sleeve 413 is used to organize and arrange the second flexible air tube 412 when it is wound up. This achieves the effect of winding up the second flexible air tube 412 and organizing and arranging it in one reciprocating movement after use, avoiding the phenomenon that the second flexible air tube 412 is easy to slip and scatter in one position, improving the neatness after use. Moreover, the winding also prevents the upper part of the second flexible air tube 412 from being scattered and exposed, affecting subsequent use, thus improving the neatness of the upper part.

[0066] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
