[0043] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements.

[0045] In order to solve the problem of low efficiency caused by the current manual or semi-automatic method of bulk material cleaning and collection, the present invention provides a material cleaning and conveying device.

[0046] The following describes this technology in detail through basic design, replacement design and extended design:

[0047] The present invention provides a material cleaning and conveying device, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the material cleaning and transporting device realizes the integrated operation of cleaning, collecting and transporting, greatly increases the stability of bulk material cleaning and collection, and is suitable for industries such as slag cleaning, food, Lianggu, medicine, chemical industry and mining industry.

[0048] The material cleaning and conveying device includes: a spiral feeding structure 1, a discharge structure 3, a buffer structure 4, a conveying structure 7 and a pneumatic source 8; wherein, the first discharge port of the spiral feeding structure 1 is connected to the second feed port 302 of the discharge structure 3; the second discharge port 303 of the discharge structure 3 and the third feed port 508 of the buffer structure 4 are connected via a first gate valve 5; the third discharge port of the buffer structure 4 and the fourth feed port 702 of the conveying structure 7 are connected via a second gate valve 6; the vent 301 of the discharge structure 3 is connected to the pneumatic source 8.

[0049] like Figure 2 As shown, the spiral feeding structure 1 is provided with a first feeding port and a first discharging port, and a spiral shaft 101 is provided in the spiral feeding structure 1. The spiral feeding structure 1 rotates through the spiral shaft 101, and the spiral blades 103 on the spiral shaft 101 screw the loose grains from the first feeding port to achieve the purpose of cleaning. The loose grains are transported along the spiral shaft 101 as the spiral shaft 101 rotates. The pneumatic source 8 is connected to the discharge structure 3, and a pressure difference is formed in the discharge structure 3 and in the pipeline 2 between the discharge structure 3 and the support 104 of the spiral feeding structure 1. Under the action of the pressure difference, the loose grains are transported to the discharge structure 3 through the pipeline 2 at the first discharging port. When the first gate valve 5 is opened, the materials entering the discharge structure 3 fall into the buffer structure 4 below, and are buffered and accumulated in the buffer structure 4. When the second gate valve 6 is opened, they fall into the conveying structure 7, and are sent out of the material cleaning and conveying device.

[0050] The spiral feeding structure 1 is equipped with an automated driving assembly, which drives the spiral shaft 101 to rotate automatically. The pneumatic source 8 is connected to the unloading structure 3, and the gas flows, automatically forming a pressure difference in the unloading structure 3, which promotes the automatic flow of materials. The first gate valve 5 and the second gate valve 6 are connected to the controller of the material cleaning and conveying device, which is automatically controlled by the controller, thereby achieving the purpose of automated cleaning and automated conveying of materials.

[0051] In some embodiments, the spiral feeding structure 1 includes a shell and a spiral shaft 101 placed at the first feed port of the shell. The shell is in the shape of a long cylinder, and a first feed port is opened on the side of the shell. The spiral shaft 101 is installed in the shell, and the two ends of the spiral shaft 101 are installed at the two ends of the shell. The spiral shaft 101 is driven by a motor. The spiral blades 103 on the spiral shaft 101 contact the bulk material during rotation, roll up the bulk material, and transport it along the spiral shaft 101. The spiral blades 103 are not set in some areas of the spiral shaft 101, but an impeller 102 is installed. The central axis of the impeller 102 is coaxial with the spiral shaft 101, and the blade diameter of the impeller 102 is larger than the diameter of the spiral blades 103 of the spiral shaft 101. The material transported on the spiral blades 103 reaches the impeller 102, and is wound and centrifugally thrown by the impeller 102. The side of the shell is also provided with a first discharge port, which is directly opposite to the rotating surface of the impeller 102. The material centrifugally thrown from the impeller 102 falls on the first discharge port and is sent into the pipeline 2 through the first discharge port. The pipeline 2 connects the spiral feeding structure 1 and the discharge structure 3.

[0052] In some embodiments, Figure 2 As shown, the spiral feeding structure 1 also includes a rolling frame 104, a roller is arranged at the bottom of the rolling frame 104, the rolling frame 104 is connected to the housing, and at least part of the pipeline 2 is placed on the rolling frame 104. The rolling frame 104 moves freely under the drive of the rolling wheel, and drives the housing, the spiral shaft 101, etc. of the spiral feeding structure 1 to move together. The freedom and convenience of movement are improved, and at the same time, the part of the pipeline 2 connected to the first discharge port of the spiral feeding structure 1 is placed on the rolling frame 104, which is convenient for carrying the pipeline 2 to move.

[0053] In different embodiments, different screw shafts 101 and impellers 102 can be selected according to the size and amount of the material. The diameters of the screw blades 103 of various screw shafts 101 are different, the diameters of various impellers 102 are also different, and the axial lengths of the impellers 102 are also different.

[0054] In addition, in different embodiments, the screw shaft 101 and the impeller 102 can be manufactured in an integrated manner, or can be detachably connected to facilitate replacement or maintenance of the impeller 102.

[0055] Due to the fluidity of the gas, under the action of the gas source 8, a pressure difference is also generated in the pipe 2 between the discharge structure 3 and the spiral feeding structure 1, and the material entering the pipe 2 automatically flows to the discharge structure 3 under the action of the pressure difference. Moreover, the pressure difference of the gas can prevent part of the material from remaining in the pipe 2 and the discharge structure 3, thereby improving the integrity and stability of material transportation.

[0056] In some embodiments, Fig.10As shown, the unloading structure 3 adopts the structure of an unloading bin, which is conical, with a second discharge port 303 at the bottom, a vent 301 at the top, a second feed port 302 at the side, and the second connecting port is connected to the pipeline 2, which is connected to the first discharge port of the spiral feeding structure 1 through the pipeline 2.

[0057] In some embodiments, in order to save energy consumption in material transportation and facilitate material transportation, the buffer structure 4 is arranged below the unloading structure 3, and the material falls into the buffer structure 4 by gravity. Fig.11 As shown, the buffer structure 4 uses a buffer bin, which is conical in shape, with a third discharge port at the bottom and a third feed port 508 at the top.

[0058] The third feed port 508 and the second discharge port 303 are connected via the first gate valve 5 , and the first gate valve 5 controls whether the second discharge port 303 and the third feed port 508 are connected.

[0059] Similarly, in order to facilitate material transportation, the conveying structure 7 is arranged below the buffer structure 4, and the material in the buffer bin falls freely from the third discharge port to the fourth feed port 702 of the conveying structure 7 below. The third discharge port and the fourth feed port 702 are connected by the second gate valve 6, and the second gate valve 6 controls whether the third discharge port and the fourth feed port 702 are connected. Figure 8 and Fig. 9 As shown, the conveying structure 7 includes: a conveying cylinder 704 and a spiral shaft 701 in the conveying cylinder 704, wherein the spiral shaft 701 in the conveying cylinder extends from the fourth feed port 702 of the conveying cylinder 704 to the fourth discharge port 703 of the conveying cylinder 704. The fourth feed port 702 is arranged at one end of the conveying cylinder 704, and the fourth discharge port 703 is arranged at the other end of the conveying cylinder 704. A spiral blade is arranged on the spiral shaft 701 in the conveying cylinder, and the spiral blade rotates with the spiral shaft 701 in the conveying cylinder 704, and the material carried by the spiral blade moves from the fourth feed port 702 to the fourth discharge port 703 along the spiral shaft 701 in the conveying cylinder.

[0060] In some embodiments, the first gate valve 5 and the second gate valve 6 may adopt the same structure. For the convenience of description, only the structure of the first gate valve 5 is described here. Those skilled in the art may design the structure of the second gate valve 6 in a similar manner based on the structure of the first gate valve 5, which will not be repeated herein.

[0061] like Figure 6 and Figure 7 As shown, a cavity is arranged inside the shell of the first gate valve 5, and an inlet and a discharge port are constructed on the shell. The inlet is used to receive materials falling from above, and the discharge port is used to discharge materials downward. The cavity constitutes a material flow channel between the inlet and the discharge port, and a driven freely slidable sliding stopper is arranged on the material flow channel between the inlet and the discharge port to open or block the material flow channel.

[0062] In some embodiments, the shell of the first gate valve 5 can be manufactured in an integrated manner or in separate parts, and connected in a detachable manner to facilitate disassembly and maintenance. Moreover, the joints are welded or detachably connected. When a detachable connection is used, the efficiency of disassembly and maintenance can be further improved.

[0063] When it is manufactured in parts, refer to the attached drawings. Figure 6 and Figure 7 As shown, the first gate valve 5 includes: a first cover 504, a second cover 505, an end cover 506 and a driving member. The first cover 504 and the second cover 505 are detachably connected, and a gasket 503 is installed at the connection to improve the sealing and stability of the connection. For example, in the accompanying drawings, the first gate valve 5 is a rectangular parallelepiped, and gaskets 503 are installed on both sides of the long side. The first cover 504 and the second cover 505 are detachably connected up and down, and both sides of the long side are connected by bolts. When disassembly is required, the bolts on both sides are opened respectively, and the disassembly speed is fast. Of course, in other embodiments, the first cover 504 and the second cover 505 can also be fixedly connected together by a snap-on method.

[0064] The first cover 504 is provided with a feed inlet, and the second cover 505 is provided with a discharge port. The feed inlet and the discharge port are arranged opposite to each other, and a material flow channel is formed between the feed inlet and the discharge port. The sliding stopper slides back and forth between the first end and the second end of the inner cavity. Specifically, the sliding stopper passes through the space between the second end of the first cover 504 and the second end of the second cover 505, and is connected to the driving member outside the first cover 504 and the second cover 505. In some embodiments, the sliding stopper is preferably a stopper or a block. The driving member is preferably a cylinder 501, and the cylinder 501 pushes out or pulls back the sliding stopper, or a motor is selected, and the motor rotates to drive the sliding stopper to slide back and forth.

[0065] It should be noted that the first cover 504 and the second cover 505 are in an upper and lower position relationship and are detachably connected, which can fully utilize the effect of gravity on material transportation. Of course, in other embodiments, the position line of the first cover 504 and the second cover 505 can also deviate from the vertical line.

[0066] An inner cavity is formed between the first cover 504 and the second cover 505 for the sliding block to slide freely; the driving member is connected to the sliding block; the end cover 506 is respectively connected to the first end of the first cover 504 and the first end of the second cover 505 to block the first end of the inner cavity, and the end cover 506 is provided with an air vent 507. When the driving member drives the sliding block to slide back and forth, gas flow will be caused. In order to achieve air pressure balance, the end cover 506 is provided with an air vent 507, which can adjust the air pressure change caused by the sliding of the sliding block to balance the air pressure in the shell cavity.

[0067] In addition, in order to facilitate maintenance and replacement, the first cover 504 and / or the second cover 505 are provided with an openable maintenance port; and / or the driving member includes a motor or a cylinder 501.

[0068] In some embodiments, considering that the sliding stopper passes through the space between the second end of the first cover 504 and the second end of the second cover 505 and is connected to the driving member, the sliding stopper will cause wear on the inner surface of the shell during the sliding process, especially the surface where the second end of the first cover 504 and the second end of the second cover 505 are close to each other, and the distance between the two gradually increases. In order to improve the stability of the connection, a wear compensation part 510 is arranged between the first end of the first cover 504 and the first end of the second cover 505, which can overcome the distance caused by wear and improve the stable connection between the first cover 504 and the second cover 505.

[0069] Since the material in the buffer structure 4 reaches a certain amount before being transported to the conveying structure 7, the buffer structure 4 is also equipped with a sensor for metering. The sensor is connected to a controller. The controller can be loaded into the main structure of the conveying device, or it can be constructed as a remote control, and the sensor and the second gate valve are connected through a remote control signal. In some embodiments, the sensor can be loaded into the second gate valve, or it can be used as a separate module of the buffer structure.

[0070] The sensor is used to measure the material value in the buffer structure. When the stress value is reached, the sensor is connected to the controller, and the controller controls the gate of the second gate valve to move according to the signal of the sensor. In some embodiments, the gate is driven by a cylinder or a motor, so the controller is connected to the cylinder or motor signal.

[0071] In other embodiments, the sensor feeds back the sensed material value to the controller, and the controller can compare the measured material value with the stress value, and when it is greater than or equal to the stress value, the second gate valve 6 is opened. In other embodiments, the sensor sends an electrical signal when the material amount reaches the stress value, and the controller opens the second gate valve 6 according to the electrical signal. Alternatively, as the material amount increases, the gate plate moves continuously, and when the material amount reaches the stress value, the controller controls the gate plate to move, and the second gate valve 6 opens.

[0072] Based on the various embodiments provided above, the material cleaning and conveying device further includes a dust removal structure 9, which is arranged on the pipeline 2 between the unloading structure 3 and the pneumatic source 8; the air inlet on the upper part of the dust removal structure 9 is connected to the pneumatic source 8, and the air outlet on the upper part of the dust removal structure 9 is connected to the air inlet of the unloading structure 3. Impurities on the upper part of the unloading structure 3 are sucked into the dust removal structure 9 under the action of the pneumatic source 8, so as to achieve the effect of purifying materials and removing dust, and obtain clean bulk materials.

[0073] A material cleaning and transporting device can be understood as a highly efficient and intelligent scattered material cleaning and transporting device. It includes Figure 1 The spiral feeding structure 1 with a trolley (which can be understood as the rolling frame 104 mentioned above) at the left end, the blower at the right end which acts as an air source 8, also includes a middle orifice sliding gate valve (i.e. the first gate valve 5 or the second gate valve 6 mentioned above), a lower spiral conveying device (i.e. the conveying structure 7 mentioned above), a material unloading bin (i.e. the unloading structure 3 mentioned above), a buffer bin (i.e. the buffer structure 4 mentioned above), a dust removal device-a cyclone separator (i.e. the dust removal structure 9 mentioned above), etc.

[0074] During the movement of the material cleaning and conveying device, the scattered materials are collected by the spiral feeding structure 1. The spiral feeding structure 1 adopts the main components such as the spiral shaft 101. The spiral blades 103 on the spiral shaft 101 roll the materials in, which can effectively reduce the labor intensity of workers, improve the collection efficiency of scattered materials, reduce the storage investment cost, change the traditional collection method, and ensure that the scattered materials are quickly and timely transported to the outside of the warehouse. The motor of the spiral feeding structure 1 drives the spiral shaft 101 to rotate. With the push of the spiral blades 103, the materials are collected and transported to the impeller 102 in the middle of the spiral shaft 101. The rotation of the impeller 102 moves the materials to the pipeline 2. The pressure difference in the pipeline 2 and the pressure difference in the unloading bin transport the collected materials to the unloading bin, and the unloading work starts after arriving at the unloading bin.

[0075] The middle orifice sliding gate valve mainly includes a cylinder 501, a gasket 503 for sealing, a wear compensation part 510, an inlet and a discharge port, etc. The middle orifice sliding gate valve is respectively located between the discharge bin and the buffer bin, and between the buffer bin and the screw conveying device. The power provided by the cylinder 501 is used to convey the material to achieve a self-cleaning pneumatic conveying movement. The device is not only energy-saving and environmentally friendly, but also does not pollute the transported materials and affect the physical properties of the materials; and because of its simple structure, easy operation, standard size and customized size, low failure rate, it greatly facilitates people's use and maintenance. The first cover 504 and the second cover 505 are connected by bolts, and the gaskets 503 on both sides of the first cover 504 and the second cover 505 can be used or disassembled at the same time to minimize downtime. The sensor in the buffer bin is sealed with a wear compensation hard polymer (i.e., the wear compensation part 510), which can be selected to extend the service life and improve the utilization rate of the equipment. In some embodiments, friction will be generated when the gate plate slides back and forth, and the wear compensation hard polymer adopts a polyurethane plate, and elastic polyurethane plates are used above and below the gate plate to compensate for the wear. A certain pressure is applied to the wear compensation hard polymer in advance, and it will be compressed and deformed under the pressure. When it wears, it compresses itself and releases part of the deformation to achieve wear compensation.

[0076] The power supply component of the lower screw conveying device is located at the left end of the screw conveying device in the figure. During the operation of the motor, the screw shaft 101 can be used to transport the material outside the bin.

[0077] The unloading bin is located in the middle and upper part of the material cleaning and conveying device, and its position is fixed by mechanical cooperation and the overall frame 104. A second feed port 302 is arranged at the left end and is connected to the pipeline 2. A second discharge port 303 is arranged at the lower part and is connected to the middle orifice sliding gate valve. A vent 301 is arranged at the right part and is connected to the cyclone separator (a form of dust removal structure 9, which can also be replaced by a centrifugal separator) through the pipeline 2. The spiral feeding structure 1 sucks the scattered material particles into the unloading bin.

[0078] The buffer bin is located at the lower part of the discharge bin and is fixed in position by mechanical cooperation with the overall frame 104. The sliding gate valve at the middle opening above opens the valve switch to deliver the material into the buffer bin.

[0079] The dust removal device - cyclone separator is located at the right position of the discharge bin in the figure. Its position is fixed by mechanical cooperation with the overall frame 104 and connected to the blower through the pipeline 2, and the purpose of dust removal is achieved by using centrifugal force.

[0080] Beneficial effects of the present invention:

[0081] The invention has reasonable structural design, standard size and customized size, and is mostly detachable and connected, so it is convenient for maintenance and cleaning and has a long service life.

[0082] The present invention has a compact and clear structure and is easy to operate. People only need to understand it briefly to use it to complete the task of collecting and transporting scattered materials, thereby minimizing the impact of personnel changes on the function of the device and improving the efficiency of timely exiting the warehouse of scattered materials.

[0083] The middle orifice sliding gate valve of the present invention has a reasonable structural design, adopts the cylinder 501 to provide power, realizes the optimization of the power element, does not consume additional energy, can effectively reduce energy waste, and the working intensity of the power element, can effectively reduce energy consumption, reduce equipment failure rate and equipment investment cost;

[0084] 4) Compared with the conventional orifice valve frame 104, the middle orifice sliding gate valve of the present invention has a simple structure, is convenient for maintenance and use, can realize internal self-cleaning, and is energy-saving and environmentally friendly.

[0087] The material cleaning and transportation device is a new type of equipment for cleaning and transporting storage products. During the cleaning process of the material, the blower as the pneumatic source 8 transmits mechanical energy to the air, so that the air generates a pressure difference and can flow in the pipe. Through the advancement of the trolley, the motor drives the screw shaft 101 to rotate. With the push of the spiral blade 103, the material is collected and transported to the impeller 102 area in the middle of the screw shaft 101. The rotation of the impeller 102 moves the material to the pipeline 2, and the material is transported and collected to the unloading bin under the pressure difference. After arriving at the unloading bin, the unloading work begins. At the moment of unloading, the upper middle orifice sliding gate valve opens, and the material reaches the buffer bin. When the material accumulates to a certain volume, the lower middle orifice sliding gate valve opens, and the material reaches the spiral discharging device, and finally sends the material out of the bin; while unloading, the dust in the material is sent to the dust removal module-cyclone separator through the pneumatic source 8 to achieve the purpose of dust removal. The whole realizes the integration of material cleaning, collection and transportation, greatly increasing the stability of slag cleaning and collection. The material cleaning and conveying device runs smoothly and can be used for multiple purposes. It is suitable for various occasions, such as food, grain, medicine, chemical industry, mineral products and other industries. At the same time, it reduces the labor cost of grain silo maintenance and indirectly improves the economic benefits of the grain silo.
