Description

Technical Field

[0001] This utility model relates to the field of powder container technology, specifically a novel powder container. Background Technology

[0002] Powder tanks, used for storing and transporting powdery materials, are typically mounted on specialized transport trucks and are collectively referred to as material tank trucks. Existing powder tanks generally have 4-6 manholes on the top for loading. The tank body of a powder / granular material tank truck is composed of symmetrical conical sections. Existing powder tanks have the following shortcomings in use:

[0003] 1. Existing powder tanks typically have 4-6 manholes on the top. During loading, local peaks easily form above each manhole, leading to uneven material accumulation. This uneven distribution not only affects the continuity and efficiency of subsequent loading but also creates underutilized empty spaces between the peaks, wasting internal tank volume and limiting the overall loading capacity of the powder tank. 2. The manholes are fitted with threaded covers, but lack an auxiliary anti-vibration mechanism. Under vibrations such as those from driving, the covers are prone to loosening due to thread vibration, resulting in poor sealing safety. 3. There is a lack of clear warning mechanisms for sealing installation, leading to the possibility of incomplete installation and suboptimal sealing.

[0004] In view of this, this application proposes a novel powder container to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a novel powder container to solve the problems mentioned in the background art.

[0011] Preferably, the rotary support spring assembly includes an inverted U-shaped plate, a compression plate, four springs, four vertical guide rods, and a turntable. The turntable is rotatably fitted onto the inner wall of the top of the corresponding internal threaded cover. The inverted U-shaped plate is fixedly connected to the bottom inner side of the corresponding bowl-shaped sealing plate. The springs are fixedly connected between the bottom of the corresponding compression plate and the bottom inner side of the bowl-shaped sealing plate.

[0014] Preferably, a circular indicator rod is fixedly connected to the top of the inverted U-shaped plate, and the internal threaded cover and the turntable are movably sleeved on the corresponding circular indicator rod. The top of the circular indicator rod is flush with the top of the corresponding internal threaded cover. An indicator hole is opened on the front side of the circular indicator rod. The distance between the bottom of the indicator hole and the top of the corresponding internal threaded cover is the same as the distance between the top of the bowl-shaped sealing plate and the inner wall of the top of the internal threaded cover.

[0015] Preferably, both the top of the turntable and the top of the internal threaded cover are provided with circular through holes that make movable contact with the outer side of the corresponding circular indicator rod.

[0016] Preferably, a pull-to-prevent-fall-off assembly is also installed between the bottom left side of the manhole and the outer side of the corresponding internal threaded cover.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. By significantly increasing the number of manholes, as in this embodiment, to 11, the addition of manholes allows for a more even distribution of material within the tank during loading.

[0024] 4. An anti-fall component designed in another way can pull the inner threaded cover to prevent it from falling off when it is reversed and removed later, thus preventing the inner threaded cover from accidentally sliding outward and injuring people during disassembly, and improving safety.

[0037] 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.

[0038] Example 1

[0039] like Figures 1 to 4 As shown, this embodiment proposes a novel powder container, including a powder container body 1 and multiple manholes 101 that are equally spaced and connected to and fixed on its top. A tensioning and anti-loosening sealing cover mechanism 2 is installed on each manhole 101. The tensioning and anti-loosening sealing cover mechanism 2 includes:

[0040] The internal threaded cover 201 is threadedly screwed onto the outside of the corresponding manhole 101; wherein the outside of the manhole 101 is provided with an external thread, which is threadedly screwed onto the corresponding internal threaded cover 201.

[0041] A bowl-shaped sealing plate 203 is installed inside the internal threaded cover 201. A bowl-shaped sealing gasket 2031 is bonded and fixed to its bottom. The bowl-shaped sealing gasket 2031 is pressed tightly against the top of the corresponding manhole 101. The internal threaded cover 201 is used to rotate upwards and separate from the corresponding manhole 101 when the personnel rotate it, or to gradually screw downwards onto the manhole 101, and to fit and press the bowl-shaped sealing plate 203 tightly.

[0042] The swivel spring tensioning assembly is rotatably fitted onto the inner wall of the top of the corresponding internal threaded cover 201 and fixedly connected to the bottom inner side of the bowl-shaped sealing plate 203. The swivel spring tensioning assembly is used to automatically and elastically tension the internal threaded cover 201 when it is screwed down. The elastic tensioning ensures that there is always an elastic tensioning force on the internal threaded cover 201, thereby keeping its inner thread in a tensioned and tight state. The constant tensioning and tightness effectively reduces the phenomenon of easy vibration and loosening due to loose thread engagement, and improves the stability of use.

[0043] A convenient foldable rotary operating component is fixedly connected to the top of the corresponding internal threaded cover 201; the convenient foldable rotary operating component is used for personnel to rotate the internal threaded cover 201.

[0044] Furthermore, such as Figure 4 As shown, the swivel support spring tension assembly includes an inverted U-shaped plate 204, a compression plate 2041, four springs 2042, four vertical guide rods 2043, and a turntable 2044. The turntable 2044 is rotatably fitted onto the inner wall of the top of the corresponding internal threaded cover 201. The inverted U-shaped plate 204 is fixedly connected to the bottom of the inner side of the corresponding bowl-shaped sealing plate 203. The springs 2042 are fixedly connected between the bottom of the corresponding compression plate 2041 and the bottom of the inner side of the bowl-shaped sealing plate 203. The top of the compression plate 2041 is fixedly connected to the bottom of the corresponding four vertical guide rods 2043. The bottom of the turntable 2044 is fixedly connected to the top of the corresponding four vertical guide rods 2043. The inverted U-shaped plate 204 is slidably sleeved on the corresponding four vertical guide rods 2043.

[0045] In this embodiment, an insert groove is provided on the inner wall of the top of the internal threaded cover 201, and a first bearing is fixedly sleeved in the insert groove. The inner ring of the first bearing is fixedly sleeved with the outer side of the corresponding turntable 2044, so as to achieve the effect of rotating and installing the turntable 2044. The top of the inverted U-shaped plate 204 is provided with four vertical guide holes, which are respectively slidably sleeved with the outer side of the corresponding vertical guide rod 2043, so as to allow the vertical guide rod 2043 to pass through and to guide its vertical sliding.

[0046] In this embodiment, through the cooperation of the inverted U-shaped plate 204, the extrusion plate 2041, four springs 2042, four vertical guide rods 2043, and the turntable 2044, when the internal thread cover 201 is rotated in the forward direction and screwed onto the outside of the corresponding manhole 101, the internal thread cover 201 drives the corresponding bowl-shaped sealing plate 203 and bowl-shaped sealing gasket 2031 to move down and press against the top of the manhole 101. The bowl-shaped sealing plate 203 is blocked and restricted by the manhole 101. During the process of continuing to rotate the internal thread cover 201 to move down and tighten it to fit and press against the bowl-shaped sealing plate 203, the internal thread cover 201 rotates on the turntable 2044 and drives it downward. The turntable 2044 moves, and the extrusion plate 2041 is driven downward by the corresponding four vertical guide rods 2043 to compress the four springs 2042. Utilizing the elastic force of the four springs 2042 in the compressed state, an elastic tension force is always maintained on the inner thread cover 201 through the extrusion plate 2041, the vertical guide rods 2043, and the turntable 2044. Under the elastic tension force, the inner thread is always in a tightened and gripped state. By using the constant tightening and gripping method, the phenomenon of easy loosening due to vibration caused by loose thread engagement is effectively reduced, thereby reducing the risk of air leakage at the top due to vibration and improving the stability of use.

[0047] Furthermore, such as Figure 2 and4 As shown, the convenient foldable rotary control assembly includes four supports 202, two iron handles 2021, and two strong magnets 2022. The top two sides of the inner threaded cover 201 are welded and fixed to the bottom of the corresponding two supports 202. The same stainless steel shaft is welded and fixed between the two supports 202 on the same side. The iron handles 2021 are rotatably sleeved on the corresponding stainless steel shaft. The top two sides of the inner threaded cover 201 are fixedly connected to the bottom of the corresponding strong magnets 2022. The bottom of the iron handles 2021 is attracted to the corresponding strong magnets 2022.

[0048] In this embodiment, the two iron handle rods 2021 located on the same internal thread cover 201 are both set to a circular structure on the opposing side. A circular through hole is opened on the front side of the circular structure. A second bearing is fixedly sleeved in the circular through hole. The inner ring of the second bearing is fixedly sleeved with the outer side of the corresponding stainless steel shaft, so as to achieve the effect of rotating and installing the iron handle rod 2021.

[0049] In this implementation scheme, four supports 202, two stainless steel shafts, two iron handles 2021, and two strong magnets 2022 work together to rotate the two iron handles 2021 on the inner thread cover 201 from top to bottom, so that the iron handles 2021 rotate outward to a horizontal position. Then, the personnel can rotate the corresponding two iron handles 2021 horizontally. The two iron handles 2021 drive the inner thread cover 201 to rotate in turn through the corresponding two stainless steel shafts and four supports 202, so as to realize the effect of allowing the personnel to rotate the inner thread cover 201. After rotation, the iron handles 2021 are rotated inward to return to the top of the inner thread cover 201 and attract the corresponding strong magnets 2022. This achieves the effect of rotating, folding, and magnetically fixing the iron handles 2021 after use, reducing the phenomenon of the iron handles 2021 protruding outward and accidentally hitting the personnel operating on the top when not in use.

[0050] Furthermore, such as Figure 2 and 4As shown, a circular indicator rod 205 is fixedly connected to the top of the inverted U-shaped plate 204. The internal threaded cover 201 and the turntable 2044 are both movably fitted onto the corresponding circular indicator rod 205. The top of the circular indicator rod 205 is flush with the top of the corresponding internal threaded cover 201. An indicator hole 2051 is provided on the front side of the circular indicator rod 205. The distance between the bottom of the indicator hole 2051 and the top of the corresponding internal threaded cover 201 is the same as the distance between the top of the bowl-shaped sealing plate 203 and the inner wall of the top of the internal threaded cover 201. The top of the turntable 2044 and the top of the internal threaded cover 201 both have circular through holes that movably contact the outer side of the corresponding circular indicator rod 205. 05 is used to slide downwards on the surface of the internal threaded cover 201 as it is gradually tightened downwards. Since the distance between the bottom of the indicator hole 2051 and the corresponding top of the internal threaded cover 201 is the same as the distance between the top of the bowl-shaped sealing plate 203 and the inner wall of the top of the internal threaded cover 201, when the top of the internal threaded cover 201 moves down to expose the indicator hole 2051, it means that the internal threaded cover 201 is in a state of hard pressing against the bowl-shaped sealing plate 203. This achieves the effect of clearly indicating whether it is tightened in place, making it easy for personnel to clearly judge whether it is tightened in place, avoiding the bowl-shaped sealing gasket 2031 from not being able to effectively seal the manhole 101 due to insufficient hard pressing, and improving the stability of the sealing operation.

[0051] It should be noted that the number of manholes 101 is preferably eight to twelve. By setting multiple manholes 101, personnel can load materials into the powder tank body 1 from multiple points above, thereby improving filling efficiency through multi-point loading. Figure 11 As shown, when six manholes are installed on the top of the powder tank, local peaks are easily formed in the area above each manhole, resulting in uneven material accumulation and unutilized empty spaces between the peaks. Figure 11 The black filler section shown in the image wastes internal volume of the tank, limiting the overall loading capacity of the powder tank. For example... Figure 9 As shown, the number of manholes in the material tank has significantly increased to 11. The effect of loading materials into the main body of the powder tank is as follows. Figure 9 As shown, the black-filled part is the unused space. It can be seen that the black-filled area is significantly smaller. The principle is to increase the number of manholes 101, so that the material can be more evenly distributed inside the tank during the loading process. This effectively smooths out the peak and trough phenomenon caused by poor material flowability and reduces the gaps and empty areas between materials. This structural optimization makes fuller use of the internal space of the tank, thereby achieving an increase in loading capacity under the same external dimensions.

[0052] It should be further noted that the internal threaded cover 201, manhole 101, bowl-shaped sealing plate 203, inverted U-shaped plate 204, extrusion plate 2041, vertical guide rod 2043, turntable 2044, support 202 and circular indicator rod 205 are all preferably made of stainless steel. The internal threaded cover 201 has a high wear-resistant and load-bearing specification with a thread gap of 1.5-3mm on the inner side. The stainless steel material has the advantages of high hardness, high wear resistance and good maintenance-free effect, which ensures the stability of long-term connection application.

[0053] This embodiment increases the number of manholes 101, enabling multi-point filling and improving filling efficiency. It automatically and elastically tightens the internal threaded cap 201 when it is tightened for sealing, ensuring the inner and outer threads are always in a state of tension and engagement. This constant tension and engagement effectively reduces the risk of loosening due to vibration, thus lowering the risk of air leakage from the upper part and improving operational stability. Furthermore, it allows for convenient and quick rotation, folding, and magnetic fixation of the iron handle 2021 after use, reducing the risk of it protruding and accidentally hitting personnel operating the upper part when not in use. Finally, it provides clear indicators to remind personnel during sealing and tightening, allowing them to clearly judge whether it is properly tightened and preventing ineffective sealing of the manhole 101 due to negligence, thus improving the stability of the sealing operation.

[0054] The method of use in this embodiment is as follows: When using the powder tank with high filling efficiency, during filling, rotate the two iron handles 2021 on the inner thread cover 201 from the top outwards, so that the iron handles 2021 are rotated outwards to a horizontal state. Then, the personnel can rotate the corresponding two iron handles 2021 horizontally. The two iron handles 2021 drive the inner thread cover 201 to rotate in the opposite direction through the corresponding two stainless steel shafts and four supports 202. The personnel can unscrew the multiple inner thread covers 201 from the corresponding manholes 101 to release the seal. By increasing the number of manholes 101, multiple manholes 101 can be used to allow personnel to fill the powder tank body 1 from multiple points from the top, thereby improving the filling efficiency by using a multi-point filling method.

[0055] During the packing and sealing process, the two iron handles 2021 on the internal threaded cover 201 are rotated outward from the top, causing them to rotate to a horizontal position. Then, personnel can rotate the two iron handles 2021 horizontally. These handles, via two corresponding stainless steel shafts and four supports 202, drive the internal threaded cover 201 to rotate. Rotating the internal threaded cover 201 forward screws it onto the outside of the corresponding manhole 101. The internal threaded cover 201 then passes through the corresponding turntable 2044 and vertical guide... Rod 2043, extrusion plate 2041, and spring 2042 drive the bowl-shaped sealing plate 203 and bowl-shaped sealing gasket 2031 to move downwards and press against the top of manhole 101. The bowl-shaped sealing plate 203 is blocked and restricted by manhole 101. As the internal thread cover 201 continues to rotate and move downwards to tighten and fit the bowl-shaped sealing plate 203, the internal thread cover 201 rotates on turntable 2044 and drives it to move downwards. Turntable 2044 drives the extrusion plate 2041 downwards to compress the four springs 2042 through the corresponding four vertical guide rods 2043. By utilizing the elastic force of four springs 2042 under compression, a constant elastic tension force is maintained on the internal thread cover 201 through the extrusion plate 2041, vertical guide rod 2043, and turntable 2044. This achieves the effect of automatically tightening the internal thread cover 201 when it is screwed on and sealed. Under this elastic tension force, the inner and outer threads are always in a state of tension and engagement. This constant tension and engagement effectively reduces the phenomenon of loosening due to vibration caused by loose threads, thereby reducing the risk of air leakage from the upper part due to vibration. This reduces the risk of accidents and improves stability. Furthermore, by forcefully pressing the bowl-shaped sealing plate 203 and the bowl-shaped sealing gasket 2031 downwards, the top of the manhole 101 is sealed. After rotation, the iron handle 2021 is rotated inwards, causing it to rotate to the top of the inner threaded cover 201 and attract the corresponding strong magnet 2022. This achieves the effect of rotating, folding, and magnetically fixing the iron handle 2021 after use, reducing the risk of the iron handle 2021 protruding outwards and accidentally hitting personnel operating or moving on the upper part when not in use.

[0056] As the internal threaded cover 201 is gradually tightened downwards, both the internal threaded cover 201 and the turntable 2044 slide downwards on the surface of the corresponding circular indicator rod 205. Since the distance between the bottom of the indicator hole 2051 and the top of the corresponding internal threaded cover 201 is the same as the distance between the top of the bowl-shaped sealing plate 203 and the inner wall of the top of the internal threaded cover 201, when the top of the internal threaded cover 201 moves down to expose the indicator hole 2051, it indicates that the internal threaded cover 201 is in a state of hard compression against the bowl-shaped sealing plate 203. This achieves the effect of clearly indicating and reminding personnel when sealing and compressing, making it easy for personnel to clearly judge whether it is tightened in place, avoiding the ineffective sealing of the manhole 101 due to negligence in not hard compression, and improving the stability of the sealing operation.

[0057] Example 2

[0058] like Figures 5 to 8 As shown, this embodiment differs from Embodiment 1 in that: a pull-and-anti-fall-off assembly is installed between the bottom left side of the manhole 101 and the outer side of the corresponding internal threaded cover 201. This assembly is used to pull and prevent the internal threaded cover 201 from falling off during subsequent reverse removal without affecting its rotation. The pull-and-anti-fall-off assembly includes a circular support ring 2061, eight sliders 2062, two fixing rings 2064, and a steel wire rope 2065. An annular groove 206 is provided on the outer side of the internal threaded cover 201, and the circular support ring 2061 is fitted onto the outer side of the corresponding internal threaded cover 201 without contacting it. Eight sliders 2062 located in the same anti-fall component are fixedly connected in a ring at equal intervals inside the circular support ring 2061. The sliders 2062 are located in the corresponding annular grooves 206. Anti-wear balls 2063 are movably embedded in the top, bottom and side of the sliders 2062 near the corresponding manhole 101. The inner wall of the top, the inner wall of the bottom and the side wall of the annular groove 206 are in contact with the corresponding anti-wear balls 2063. The bottom left side of the manhole 101 and the bottom left side of the circular support ring 2061 are welded and fixed to the corresponding fixing rings 2064. The steel wire rope 2065 is fixedly installed on the two corresponding fixing rings 2064.

[0059] It should be noted that the wire rope 2065, the circular support ring 2061, the eight sliders 2062, and the fixing ring 2064 are all preferably made of stainless steel. The wire rope 2065 is preferably made of a load-bearing capacity that is at least three times greater than the total weight of the structure on the internal thread cover 201. This load-bearing capacity selection method, which exceeds the weight of the tension structure, is a well-known technique in tension stress and will not be elaborated further. In addition, the advantages of stainless steel, such as high hardness, high wear resistance, and good maintenance-free performance, are utilized to ensure the stability of long-term connection applications.

[0060] This embodiment can pull and support the internal threaded cover 201 to prevent it from falling off when it is reversed and removed, thus preventing the internal threaded cover 201 from accidentally sliding outward and injuring people during disassembly, thereby improving safety.

[0061] The usage method of this embodiment is as follows: Based on Embodiment 1, the difference from Embodiment 1 is that: by using the circular support ring 2061, eight sliders 2062, multiple anti-wear balls 2063, two fixing rings 2064, and steel wire rope 2065 in cooperation, the eight sliders 2062 and multiple anti-wear balls 2063 achieve the effect of movably engaging and preventing detachment between the circular support ring 2061 and the internal threaded cover 201. When the internal threaded cover 201 rotates, it drives the annular groove 206 to slide on the surface of multiple anti-wear balls 2063, utilizing multiple... The anti-wear ball bearing 2063 reduces the grinding phenomenon. After the internal thread cover 201 is separated from the manhole 101, the steel wire rope 2065, together with the corresponding two fixing rings 2064, is used to pull and restrict the circular support ring 2061. Furthermore, multiple sliders 2062 and annular grooves 206 further pull and restrict the internal thread cover 201, so as to prevent it from falling off when the internal thread cover 201 is reversed and removed. This prevents the internal thread cover 201 from accidentally sliding outward and injuring people during disassembly, thus improving the safety of use.
