Description

Technical Field

[0001] The invention relates to a dynamic material gathering and collecting device with positioning function for powder (granular material) loading and shipping and a dynamic material collecting method. Background Art

[0002] Most industrial powder materials have fine particles, strong fluidity, easy to lose and be contaminated. At present, this kind of powder materials are often shipped in car boxes and ship holds. When unloading, the powder materials are sucked out by the fan through the discharge channel extending into the discharge port on the top of the car. When the wind discharges, the powder materials far away from the discharge channel remain and are difficult to be sent out. Usually, the final residual amount reaches 10%-30% of the total amount, and it is necessary to manually enter the car to clean it up later, which is time-consuming and labor-intensive, and the overall collection speed is slow and the efficiency is low.

[0003] The applicant previously applied for a "dynamic air bag material gathering and collection device and dynamic material collection method" with application number "2020102835260". The bag body is lifted up by the air pressure sent into the inflation joint pipe under the traction of the guide support rod, and at the same time, the bag bodies on both sides of the top of the bag body are lifted up toward the center under the action of air pressure, thereby forming a downward slope on both sides of the loading cavity toward the center, which is convenient for centralized discharge of materials. However, in actual use, due to the imbalance of air pressure at both ends of the bag body in the horizontal direction, the bag body is not raised and lowered synchronously, and the bag body is also lifted up asynchronously in the longitudinal direction, which causes the concentrated position of the final material to often deviate and cannot be fully discharged. Therefore, its improvement and innovation are imperative. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a dynamic material gathering and collecting device and a dynamic material collecting method with a positioning function, which can effectively solve the problems of large residual amount and low discharge efficiency of wind-powered material discharge in the carriage.

[0005] The technical solution provided by the present invention is:

[0006] A dynamic material gathering and collecting device with a positioning function comprises a box body, which is a hollow structure with an opening at the top, a supporting bag body placed in the box body, the supporting bag body being a hollow structure made of a deformable airtight material, a material port communicating with the inside and outside being provided at the top center of the supporting bag body, a positioning bag body made of a deformable airtight material being suspended in the supporting bag body, the peripheral edge of the positioning bag body being sealed and connected to the upper inner wall of the supporting bag body, the space between the supporting bag body and the positioning bag body forming an inflation cavity, a sealing clip chain arranged along the length direction of the box body is provided between the upper surface of the bottom surface of the supporting bag body just below the material port and the lower surface of the bottom surface of the positioning bag body, the upper surface of the bottom surface of the supporting bag body and the lower surface of the bottom surface of the positioning bag body being connected together by the sealing clip chain, and an inflation joint pipe communicating with the inflation cavity is provided on the side walls at both ends of the box body.

[0007] Preferably, the sealing clip chain includes a convex strip fixed on the lower surface of the bottom surface of the positioning bag body and a concave strip fixed on the upper surface of the bottom surface of the supporting bag body. A convex buckle is arranged on the convex strip, and a groove corresponding to the convex buckle is arranged on the concave strip. The convex buckle is placed in the groove to form a detachable sealing connection structure.

[0008] Preferably, the center line of the sealing clip chain is located directly above the transverse center line of the box body.

[0009] A method for dynamically discharging powder materials using the above-mentioned material gathering and collecting device comprises the following steps:

[0010] 1. Loading

[0011] Place the bag body in the box, load the powder material into the positioning bag body from the material opening at the top center of the supporting bag body, and then install the top cover matching the material opening on the material opening to seal it, and then the loading is completed;

[0012] At this time, the upper surface of the bottom surface of the supporting bag body and the lower surface of the bottom surface of the positioning bag body are connected together through the sealing clip chain, the powder material is pressed on the positioning bag body, and the material opening is located just above the center of the sealing clip chain;

[0013] 2. Unloading

[0014] After the box is transported to the destination, the inflation joint pipe is connected to the air outlet of the air pump through the inflation pipe, the top cover is opened, and the feeding pipeline is inserted into the inner cavity of the positioning bag from the material port. At the same time, the air pump and the exhaust fan on the feeding pipeline are started. Under the action of the exhaust fan, the powder material in the central part of the inner cavity of the positioning bag is sent out from the lower port of the feeding pipeline under the action of negative pressure. At the same time, the compressed gas at the air outlet end of the air pump enters the inflation cavity between the supporting bag body and the positioning bag body from the inflation joint pipe. As the powder material is sent out, the powder material in the center of the loading cavity is sent out first, so that a groove is gradually formed in the center. At the same time, the feeding pipeline is continuously moved downward during the discharging process. As the groove increases, the powder material on both sides continuously gathers in the middle In the process, since the thickness of the powder materials on both sides is continuously reduced along the vertical direction, that is, the weight of the powder materials on both sides is continuously reduced, the positioning bags on both sides are finally lifted up by air pressure, and the concave and convex strips of the sealing clip chain are separated from both ends under the action of air pressure. With the separation of the concave and convex strips of the sealing clip chain, the positioning bags on both ends of the box body are gradually lifted up and toward the center by air pressure, and at the same time, the two ends of the positioning bags on both sides of the box body are also gradually lifted up and toward the center by air pressure, so that the upper surface of the positioning bag body gradually forms a slope inclined from all sides to the center, and the powder material is continuously concentrated toward the center along the slope and sent out from the lower opening of the feeding pipeline, so that all the powder material in the loading chamber is cleaned up, so that there is no residue when collecting the material.

[0015] The present invention has a novel and unique structure, is simple and reasonable, easy to produce and easy to operate. The bag body adopts an airtight inner and outer double-layer structure composed of a supporting bag body and a positioning bag body, so that an inflation cavity is formed between the supporting bag body and the positioning bag body, and the inflation cavity is inflated through an inflation joint tube, and the deformation process of the positioning bag body is controlled by air pressure; a sealing clip chain arranged along the length direction of the box body is provided between the upper surface of the bottom surface of the supporting bag body and the lower surface of the bottom surface of the positioning bag body, and the concave and convex strips of the sealing clip chain are interlocked with each other, so that the upper surface of the bottom surface of the supporting bag body is connected to the lower surface of the bottom surface of the positioning bag body, and at the same time, the two ends of the concave and convex strips can be gradually separated from the two ends under the action of air pressure, thereby playing a guiding role in the deformation of the positioning bag body, and the center line of the sealing clip chain is located at the box body. Directly above the horizontal center line, in the process of separating the sealed clip chain powder from both ends and forming a slope in the positioning bag body, the sealed clip chain is always used as a reference, so that the powder material is always pushed toward the center line by the positioning bag body, ensuring that the final concentrated position of the powder material is just below the material port, and can be concentratedly sent out through the feeding pipeline, so that all the powder material in the loading chamber is cleaned up, so that there is no residue when collecting the material. When the traditional wind feeding method is used for collecting the material, there will often be 10%-30% residue, which needs to be cleaned manually. The technical solution of the present application has achieved almost completely no residue, greatly improved the efficiency of collecting the material, shortened the unloading time, saved the unloading cost, was easy to use, and had good effect. It is an innovation in the powder material loading and unloading device. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0024] Depend on Figure 1-10 The present invention includes a box body 1, which is a hollow structure with an opening at the top. A supporting bag body 2 is placed in the box body 1. The supporting bag body 2 is a hollow structure made of a deformable airtight material. A material port 7 that is connected to the inside and outside is provided at the top center of the supporting bag body 2. A positioning bag body 3 made of a deformable airtight material is suspended in the supporting bag body 2. The periphery of the positioning bag body 3 is sealed and connected to the upper inner wall of the supporting bag body 2. The space between the supporting bag body 2 and the positioning bag body 3 constitutes an inflation chamber 11. A sealing clip chain 5 arranged along the length direction of the box is provided between the upper surface of the bottom of the supporting bag body 2 just below the material port 7 and the lower surface of the bottom of the positioning bag body 3. The upper surface of the bottom of the supporting bag body 2 and the lower surface of the bottom of the positioning bag body 3 are connected together by the sealing clip chain 5. An inflation joint pipe 4 that is connected to the inflation chamber 11 is provided on the side walls at both ends of the box body 1.

[0025] The box body 1 is a rectangular hollow structure made of a non-deformable airtight material, such as a steel plate, etc., with an open upper end surface to form a rectangular container structure.

[0026] The support bag body 2 and the positioning bag body 3 are both made of deformable airtight materials, such as rubber tarpaulin, aramid cloth with rubber covering the surface, etc. After being inflated, the positioning bag body 3 will deform under the action of air pressure.

[0027] To ensure the use effect, the sealing clip chain 5 includes a convex strip 51 fixed on the lower surface of the bottom surface of the positioning bag body 3 and a concave strip 52 fixed on the upper surface of the bottom surface of the supporting bag body 2. A convex buckle is arranged on the convex strip, and a groove corresponding to the convex buckle is arranged on the concave strip. The convex buckle is placed in the groove to form a detachable sealing connection structure. The convex strip 51 and the concave strip 52 are both made of plastic with good elasticity and flexibility or silicone material with high hardness. The size of the concave and convex strips interlocking with each other ensures that they are not easy to fall out, but they can be separated from one end of the concave and convex strips under a certain air pressure. The length of the concave strip is slightly larger than the convex strip, which is convenient for the concave and convex strips to be separated and opened.

[0028] The center line of the sealing clip chain 5 is located directly above the transverse center line of the box. In the process of separating the powder from both ends of the sealing clip chain and forming a slope in the positioning bag, the sealing clip chain is always used as a reference, so that the powder material is always pushed toward the center line by the positioning bag, and finally can be sent out in a centralized manner directly below the material outlet.

[0029] There are two inflatable joint pipes 4 at both ends of the box body, and the two inflatable joint pipes 4 on the same side are respectively connected to the inflatable cavities on both sides of the sealing clip chain, so that the inflation is more uniform, and it is convenient to have enough air pressure to lift the positioning bag body, so that the sealing clip chain starts to separate from both ends.

[0030] The inflation joint pipe 4 is connected with an inflation pipeline, and the air inlet end of the inflation pipeline is connected with the air outlet of the air pump to form an inflation structure of the inflation cavity.

[0031] A feeding pipeline 10 extending into the inner cavity of the positioning bag body 3 is inserted in the center of the material opening 7, and an exhaust fan is installed at one end of the feeding pipeline 10 extending out of the box body.

[0032] A powder flow meter can be set on the feeding pipeline 10 to monitor its flow rate. As the discharging proceeds, the feeding pipeline is moved downward. It can be lifted manually or by a clamping mechanism. For example, an annular airbag with the same structure as in the "Powder Material Loading Device with Dynamic and Rapid Discharging Function" with application number 2019111909275 previously applied by the applicant can be used for lifting, so that it always maintains a small distance of 3-5 cm from the material surface, ensuring the release of pressure and facilitating discharging.

[0033] The powder flow meter can monitor the flow of powder materials in real time, which is a prior art. For example, the powder flow meter HDLDG-06 sold by Wuhan Huadelin Technology Co., Ltd. can be used.

[0034] The top of the support bag body 2 is connected to a hanging rope 6 for connecting it to the outer wall of the box body 1, and the end of the hanging rope 6 away from the support bag body is connected to a hook 6a. A hanging ear corresponding to the hook is fixedly connected to the outer wall of the box body 1, and the hook is hung in the hanging ear to form a connection structure between the support bag body and the box body. When loading, the hook is hung in the hanging ear to connect the upper part of the support bag body to the box body, so as to prevent the support bag body from collapsing into the inner cavity of the box body during loading.

[0035] A method for dynamically discharging powder materials using the above-mentioned material gathering and collecting device comprises the following steps:

[0036] 1. Loading

[0037] Place the bag in the box, load the powder material 9 into the positioning bag from the opening 7 at the top center of the supporting bag 2, and then install the top cover 8 matching the opening on the opening to seal it, and the loading is completed (such as Figure 3 , 4 shown);

[0038] At this time, the upper surface of the bottom of the supporting bag body 2 and the lower surface of the bottom of the positioning bag body 3 are connected together through the sealing clip chain 5, the powder material is pressed on the positioning bag body, and the material opening is located just above the center of the sealing clip chain;

[0039] 2. Unloading

[0040] After the box is transported to the destination, the inflation joint pipe 4 is connected to the air outlet of the air pump through the inflation pipe, the top cover 8 is opened, and the feeding pipeline 10 is inserted into the cavity of the positioning bag from the material port 7. At the same time, the air pump and the exhaust fan on the feeding pipeline 10 are started. Under the action of the exhaust fan, the powder material 9 in the central part of the cavity of the positioning bag is sent out from the lower port of the feeding pipeline 10 under the action of negative pressure (such as Fig.10 As shown), at the same time, the compressed gas at the outlet end of the air pump enters the inflation chamber 11 between the supporting bag body and the positioning bag body from the inflation joint pipe 4. As the powder material is sent out, the powder material in the center of the charging chamber is sent out first, so that a groove is gradually formed in the center. At the same time, the feeding pipeline is continuously moved downward during the discharging process. As the groove increases, the powder materials on both sides are continuously concentrated in the middle. Since the thickness of the powder materials on both sides along the vertical direction is continuously reduced, that is, the weight of the powder materials on both sides is continuously reduced, the positioning bags on both sides are finally lifted up by the air pressure, and the concave and convex strips of the sealing clip chain are separated from both ends under the action of the air pressure (as shown in FIG. Figure 5 , 6 As the concave and convex strips of the sealing clip chain separate, the positioning bags on both ends of the box body are gradually lifted upward and toward the center by air pressure, and at the same time, the two ends of the positioning bags on both sides of the box body are also gradually lifted upward and toward the center by air pressure, so that the upper surface of the positioning bags gradually forms a slope that tilts from the surroundings to the center (as shown in FIG. Figure 7 8), the powder material is continuously concentrated toward the center along the slope and is sent out from the lower opening of the feeding pipeline, so that all the powder material in the charging chamber is cleaned up and no residue is left when receiving the material.

[0041] It should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0042] Compared with the prior art, the present invention has the following advantages:

[0043] 1. The bag body adopts an airtight inner and outer double-layer structure consisting of a supporting bag body and a positioning bag body, so that an inflatable cavity is formed between the supporting bag body and the positioning bag body. The inflatable cavity is inflated through the inflatable joint pipe, and the deformation process of the positioning bag body is controlled by air pressure;

[0044] 2. A sealing clip chain arranged along the length direction of the box body is provided between the upper surface of the bottom surface of the supporting bag body and the lower surface of the bottom surface of the positioning bag body. The concave and convex strips of the sealing clip chain are engaged with each other, so that the upper surface of the bottom surface of the supporting bag body and the lower surface of the bottom surface of the positioning bag body are connected together. At the same time, the two ends of the concave and convex strips can be gradually separated from the two ends under the action of air pressure, thereby playing a guiding role in the deformation of the positioning bag body;

[0045] 3. The center line of the sealed clip chain is located directly above the horizontal center line of the box. In the process of separating the powder from both ends of the sealed clip chain and forming a slope in the positioning bag body, the sealed clip chain is always used as a reference, so that the powder material is always pushed toward the center line by the positioning bag body, ensuring that the final concentrated position of the powder material is just below the material port, and can be sent out in a centralized manner through the feeding pipeline, so that all the powder materials in the charging cavity are cleaned up, so that there is no residue when collecting the material. When collecting the material by traditional wind feeding method, there is often 10%-30% residue, which needs to be cleaned manually. The technical solution of this application achieves almost no residue, which greatly improves the efficiency of collecting the material;

[0046] 4. Due to the lifting by wind pressure, the upper surface of the positioning bag gradually forms a slope inclined from the surrounding to the center, which greatly improves the efficiency of collecting materials. After practical application, the same or similar technical effects have been achieved. Taking 60 tons of alumina powder as an example, it takes more than 80-90 minutes to unload. The dynamic air bag gathering and collecting device of the present application takes only 20-25 minutes to collect materials, which greatly improves the efficiency of unloading, shortens the time of unloading, and saves the cost of unloading.

[0047] 5. There is only one material port on the top of the box, which takes into account both loading and unloading;

[0048] 6. The discharge pipeline is detachable and does not need to be transported with the vehicle, nor does it need to be fixed on the discharge port all the time, which also avoids the risk of blockage of the discharge pipeline during transportation;

[0049] 7. Using compressed air for unloading not only improves loading and unloading efficiency, but also does not cause pollution to raw materials.

[0050] The applicant also needs to point out that what is mentioned above in this application is merely an embodiment and is not intended to limit the scope of protection of this application. Any technical solution that is essentially the same as the technical solution of this application made by equivalent or equivalent alternative means shall fall within the scope of protection of this application.
