Technical Field

[0001] This invention relates to the field of special vehicle technology, and in particular to a powder tanker truck and its powder tank container. Background Technology

[0002] Powder tank trucks are specialized tank vehicles used for transporting bulk powder materials, such as cement, pulverized coal, fly ash, talc powder, and flour. Bulk transportation of powder materials can improve transportation efficiency, save on transportation costs, and reduce product costs.

[0003] Currently, powder tanker trucks consist of a frame, tank body, air inlet pipe, and unloading pipe. The powder inside the tank is pressurized through the air inlet pipe to form a fluidized state, and then discharged through the unloading pipe, thus achieving the desired result.

[0004] The bottom of the tank is equipped with a fluidizing cloth, which divides the interior of the tank into a material chamber and a gasification chamber. The material chamber is located above the fluidizing cloth. After the powder or granular material is pressed onto the fluidizing cloth, the material is supported by the fluidizing cloth. Over time, the fluidizing cloth is easily damaged. However, the fluidizing cloth inside the current powder tank container is not easy to disassemble, install, repair, or replace. Summary of the Invention

[0005] The purpose of this invention is to provide a powder tanker truck and its powder tank container to solve the problem of difficult disassembly and assembly of fluidized cloth in the powder tank container in the prior art.

[0011] In one embodiment, the top of the base plate has an upwardly protruding post, and the outer periphery of the protruding post has threads to form the fastener.

[0012] In one embodiment, the surface area of ​​the base plate is larger than the surface area of ​​the cover plate, and the base plate covers the cover plate.

[0013] In one embodiment, a gap exists between the lower surface of the fluidizing element and the bottom end cap to form a accommodating space for accommodating the intake pipe.

[0021] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0022] To further illustrate the principles and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0023] This invention provides a powder tanker truck. The powder tanker truck includes a vehicle body and a powder tank container, the powder tank container being fixedly mounted on the vehicle body. The powder tank container is used to load powder, and the powder tanker truck is used to transport the powder tank container. The powder loaded in the powder tanker truck can be chemical granules or food-grade granules. For ease of explanation, the travel direction of the powder tanker truck is defined as longitudinal, the direction perpendicular to the travel direction as transverse, and the forward direction of the powder tanker truck as forward.

[0024] See Figure 1 The powder tank container includes a tank body 1, a fluidizing component 2, a support component 3, a cover plate 4, and an air inlet pipe (not shown in the figure).

[0025] Tank 1 is used to load powder. Specifically, in this embodiment, tank 1 is placed horizontally, and the horizontal length of tank 1 is less than its vertical length. The axial direction of tank 1 is consistent with the travel direction of the powder tanker truck. In other embodiments, tank 1 can also be placed vertically, and the axial direction of tank 1 is perpendicular to the travel direction of the powder tanker truck.

[0026] Specifically, the tank body 1 includes a cylindrical body 11 and a plurality of bottom end caps 12 disposed at the bottom of the cylindrical body 11.

[0027] The bottom of the cylinder 11 has multiple openings. The top of the cylinder 11 has a feed port for injecting powder, and the bottom has an air inlet for injecting compressed air.

[0028] The cylinder 11 includes a cylinder body 111 and fixed flanges 112, each fixed flange 112 corresponding to one of the openings. Specifically, the fixed flanges 112 are welded to the outer periphery of the openings in the cylinder 11. In this embodiment, the fixed flanges 112 are annular, and the outer periphery of the fixed flanges 112 is provided with a plurality of first fixing holes. The plurality of first fixing holes are evenly distributed along the outer periphery of the fixed flanges 112.

[0029] The bottom end cap 12 is set to correspond one-to-one with each opening on the cylinder 11 to close the cylinder 11.

[0030] Specifically, each bottom end cap 12 includes an end cap body 121, a connecting flange 122, and a base plate 123.

[0031] Each connecting flange 122 corresponds to one of the fixed flanges 112. Specifically, the connecting flange 122 is annular and is fixedly connected to the head body 121. In this embodiment, the connecting flange 122 is welded to the head body 121.

[0032] The connecting flange 122 has multiple second fixing holes corresponding to the first fixing hole on its outer periphery. Fasteners pass through the first and second fixing holes to achieve a detachable connection between the fixing flange 112 and the connecting flange 122. The fasteners include bolts and nuts. When assembly is required, simply insert the bolts into the first and second fixing holes and tighten the nuts; when disassembly is required, unscrew the nuts and remove the bolts. In other embodiments, the fasteners can also be rivets.

[0033] See Figure 2 and Figure 3 The inner wall of the top of the connecting flange 122 has a protrusion 124. The width of the protrusion 124 gradually decreases in the direction away from the outer periphery of the connecting flange 122, and the maximum width of the protrusion 124 is less than the width of the connecting flange 122. Therefore, the bottom of the connecting flange 122 extends beyond the protrusion 124.

[0034] In this embodiment, the head body 121 is spherical. In other embodiments, the head body 121 may also be disc-shaped, elliptical, or hemispherical.

[0035] The head body 121 is welded to the connecting flange 122, so the cylinder 11 and the bottom head 12 are detachably connected, which facilitates the inspection and replacement of the fluidizing element 7 from the bottom of the tank 1.

[0036] Continue reading Figure 2 and Figure 3 In this embodiment, the end cap body 121, the protrusion 124, and the connecting flange 122 form a groove 6.

[0037] In other embodiments, the slot 6 can be directly formed on the inner wall of the connecting flange 122 or directly formed on the inner wall of the end cap body 121.

[0038] See Figure 2 and Figure 3 The base plate 123 is fixed to the bottom of the end cap body 121. Specifically, the base plate 123 is circular, and therefore its outer circumferential curve is smooth. The base plate 123 has multiple mounting holes. In this embodiment, the multiple mounting holes are evenly distributed along the outer circumference of the base plate 123.

[0039] Fluidizing elements 2 are correspondingly installed in each bottom end cap 12. The fluidizing elements 2 divide the tank body 1 into a powder chamber and an atmospheric chamber, with the powder chamber located above the fluidizing elements 2 and the atmospheric chamber located below the fluidizing elements 2. The air inlet is located in the atmospheric chamber, allowing compressed air to be introduced into the atmospheric chamber.

[0040] The fluidizing element 2 has air permeability, which allows the compressed air that is filled into the air vaporization chamber to pass through the fluidizing element 2 and cause the powder in the tank 1 to be fluidized under the action of the airflow.

[0041] In this embodiment, the fluidizing element 2 is made of canvas, specifically polyester, polyester-cotton blend, nylon, cotton, linen, or cotton-linen blend. In other embodiments, the fluidizing element 2 can also be made of metal, such as steel wire, woven into a mesh to allow compressed air to pass through through holes; it can also be made of stainless steel or titanium wire. The fluidizing element 2 can also be made of plastic, such as nylon, PVC, PE, PTFE, or polyester. The fluidizing element 2 can also be made of composite materials, such as fiberglass. The middle part of the fluidizing element 2 is connected and fixed to the base plate 123, and the outer periphery of the fluidizing element 2 is located within the slot 6, making the fluidizing element 2 an inverted frustum shape.

[0042] A gap exists between the lower surface of the fluidizing element 2 and the bottom end cap 12, forming a receiving space. The size of this receiving space can be determined by adjusting the size of the base plate 123. For example, when the size of the base plate 123 is larger, the middle part of the fluidizing element 2 is connected to the base plate 123, and the space between the lower surface of the fluidizing element 2 on both sides of the base plate 123 and the bottom end cap 12 is the receiving space, which is smaller in this case. When the size of the base plate 123 is smaller, the receiving space is larger.

[0043] Specifically, the fluidizing element 2 has multiple through holes in the middle that correspond to the mounting holes.

[0044] The fluidizing element 2 has a limiting edge on its outer periphery, resulting in a thicker outer periphery. The limiting edge abuts against the outer wall of the support element 3. Specifically, the limiting edge is integrally formed with the fluidizing element 2.

[0045] In this embodiment, the fluidizing element 2 is circular. The size of the fluidizing element 2 is sufficient to connect its center to the base plate 123, and its outer periphery is disposed in the slot 6.

[0046] The intake pipe is located inside the bottom end cap 12 and is connected to the intake port to fill the atmospheric chamber with compressed air. Specifically, the intake pipe is located within the accommodating space.

[0047] The support member 3 is provided in a one-to-one correspondence with the bottom end cap 12. The support member 3 is snapped into the slot 6 and engaged with the bottom end cap 12 to support and fix the fluidizing element 2 within the bottom end cap 12. Specifically, the support member 3 is annular and is adapted to the annular connecting flange 122. In this embodiment, the cross-section of the support member 3 is a smooth curve, such as a circle, so that there are no sharp edges when the support member 3 contacts the fluidizing element 2, reducing damage to the fluidizing element 2.

[0048] Furthermore, the limiting edge abuts against the outer wall of the support member 3, making the thickness of the fluidizing member 2 inside the slot 6 less than the thickness outside the slot 6, reducing the probability of the fluidizing member 2 falling off and increasing the stability of the fluidizing member 2 inside the slot 6.

[0049] The cover plate 4 is provided in a one-to-one correspondence with the bottom end cap 12, and the cover plate 4 is positioned above the fluidizing element 2. Specifically, the cover plate 4 is provided with multiple connecting holes corresponding to the mounting holes. In this embodiment, the cover plate 4 is circular, so the outer circumference curve of the cover plate 4 is smooth. Furthermore, the cover plate 4 is permeable to compressed air.

[0050] In this embodiment, the diameter of the cover plate 4 is smaller than the diameter of the base plate 123, that is, when the cover plate 4 is placed on the base plate 123, the cover plate 4 is completely covered by the base plate 123. In other embodiments, the diameter of the cover plate 4 may be equal to the diameter of the base plate 123, or the diameter of the cover plate 4 may be larger than the diameter of the base plate 123.

[0051] Fasteners are provided with connecting holes, through holes and mounting holes to enable detachable connection between fluidizing component 2, cover plate 4 and bottom plate 123, thereby enabling detachable connection between fluidizing component 2 and bottom end cap 12.

[0052] In this embodiment, the top of the base plate 123 has an upwardly protruding post, and the outer periphery of the protruding post has threads to form a fastener. This design facilitates the connection between the base plate 123 and the fluidizing element 2 and the cover plate 4. That is, the fluidizing element 2 is directly laid on the base plate 123, and then the cover plate 4 is placed on the fluidizing element 2.

[0053] The disassembly and assembly process of the fluidization device for the powder tank container of the present invention is as follows:

[0054] By removing the fasteners of the fixed flange 112 on the cylinder 11 and the connecting flange 122 of the bottom end cap 12, the bottom end cap 12 can be opened. Then, the support 3 is removed from the slot 6 of the bottom end cap, and the connection between the outer periphery of the fluidizing element 2 and the top of the bottom end cap 12 is released. Then, the fasteners between the cover plate 4 and the bottom plate 123 are removed, and the connection between the middle part of the fluidizing element 2 and the bottom of the bottom end cap 12 is released, thereby completing the disassembly of the fluidizing element 2 and the tank 1.

[0055] After disassembling fluidizing element 2, a new, intact fluidizing element 2 is taken and welded to the fastener on the bottom head 12, aligning its through hole with the fastener. Then, the connecting hole of the cover plate 4 is aligned with the fastener, and the cover plate 4 is installed, covering the fluidizing element 2. The cover plate 4, fluidizing element 2, and bottom plate 123 are then connected and fixed. Next, the outer periphery of the fluidizing element 2 is inserted into the slot 6 of the bottom head 12 using the support 3, completing the connection between the fluidizing element 2 and the bottom head 12. Finally, the fixing flange 112 on the cylinder 11 is connected and fixed to the connecting flange 122 of the bottom head 12, completing the connection between the cylinder 11 and the bottom head 12, thus completing the installation process of the fluidizing element 2.

[0056] As can be seen from the above technical solution, the advantages and positive effects of the present invention are as follows: The powder tank container of the present invention includes a tank body, a fluidizing component, and a supporting component. The inner peripheral wall of the bottom end cap of the tank body has a groove, the middle part of the fluidizing component is detachably connected to the bottom of the bottom end cap, the outer periphery of the fluidizing component is located within the groove, and the supporting component is inserted into the groove to support and fix the fluidizing component, thus achieving a detachable connection between the fluidizing component and the bottom end cap. Therefore, the fluidizing component is easy to assemble and disassemble, making the manufacturing and installation of the powder tank container simpler and subsequent maintenance and replacement more convenient.

[0057] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims.
