Description

Technical Field

[0001] The present application relates to the technical field of bulk material loading, and in particular to a bulk material uniform loading system for a silo side wall. Background Art

[0002] Bulk materials are usually stored in silos. When the bulk materials in the silo need to be transported out, the loading system installed on the side wall of the silo is required.

[0003] The existing loading system includes a discharge pipe connected to the side wall of the silo, a discharge hopper connected to the discharge pipe, an electric valve arranged on the discharge pipe, and a monitoring device for controlling the position of the truck. When in use, a person manually directs the truck to move accurately to the bottom of the discharge hopper through the monitoring device, opens the electric valve, and allows the bulk material in the silo to be loaded into the truck bed from the discharge pipe through the discharge hopper. The person manually directs the truck to move through the monitoring device, so that the bulk material gradually fills the truck bed, so that the bulk material in the silo can be loaded into the truck bed.

[0004] In the above-mentioned loading process, although the flow of bulk materials from the silo to the truck is realized, since a conical material pile will always be formed when the bulk materials are loaded from the lower hopper into the truck bed, the bulk materials are prone to appear wavy in the truck bed, and the material pile needs to be manually flattened after loading, which increases the bulk material loading time and thus reduces the bulk material loading efficiency. Summary of the invention

[0005] In order to enable bulk materials to be directly and evenly loaded into a truck bed to improve bulk material loading efficiency, the present application provides a bulk material evenly loading system for a silo side wall.

[0006] The present application provides a bulk material uniform loading system for the silo side wall, which adopts the following technical solution: A bulk material uniform loading system for the side wall of a silo is used for transferring bulk material from the silo to a truck bed, comprising a loading assembly, a discharge assembly and a material control assembly, the loading assembly comprising a feed pipe, a loading pipe rack, a discharge pipe and a support frame, the feed pipe is connected to the top end of the loading pipe rack, a plurality of discharge pipes are provided and are all connected to the bottom end of the loading pipe rack, the plurality of discharge pipes are arranged in a rectangular array, the loading pipe rack is provided on the support frame, and the support frame is supported on the ground, the discharge assembly is provided between the side wall of the silo and the feed pipe, and is used for flowing bulk material in the silo to the feed pipe, the material control assembly is provided at the discharge pipe, and is used for opening all the discharge pipes when bulk material accumulates in the feed pipe, the loading pipe rack is used to cooperate with the material control assembly to make the bulk material in the feed pipe flow uniformly to each discharge pipe, and the discharge amount of the discharge assembly is equal to the sum of the discharge amounts of all the discharge pipes.

[0007] By adopting the above technical scheme, the bulk material in the silo can flow to the feed pipe through the material discharge component, and the bulk material flows from the feed pipe to the discharge pipe through the loading pipe rack. When the bulk material has not accumulated in the feed pipe, the material control component can close all the discharge pipes, so that the bulk material can first accumulate in the loading pipe rack and the discharge pipe. When the material control component closes the discharge pipe, the loading pipe rack can guide the bulk material to flow evenly to each discharge pipe, so that the bulk material in the discharge pipe and the loading pipe rack is easy to be in a dense state.

[0008] When bulk material accumulates at the feed pipe, the material control component opens all the discharge pipes, so that the bulk material can flow out from all the discharge pipes in a dense state synchronously. Since the discharge amount of the discharge component is equal to the sum of the discharge amounts of all the discharge pipes, the total amount of bulk material in the loading pipe rack is always in a dynamic equilibrium state, so that the bulk material can flow into the truck bed from each discharge pipe continuously and stably in a dense state. Multiple discharge pipes arranged in a rectangular array drop materials into the truck bed synchronously, making it easy to load the bulk material synchronously in the truck bed, so that the bulk material can be directly and evenly loaded into the truck bed without the need to manually flatten the material pile, thereby improving the efficiency of bulk material loading.

[0009] Optionally, the loading tube rack includes a distribution tube and a balancing tube. The distribution tube is provided with a feed port and two discharge ports. The discharge amounts of the two discharge ports of the distribution tube are consistent. There are multiple distribution tubes, and there are more than two layers arranged from the feed tube to the discharge tube. Between two adjacent layers of distribution tubes, the number of the lower layer distribution tubes is twice the number of the upper layer distribution tubes. The feed ports of the lower layer distribution tubes are connected to the discharge ports of the upper layer distribution tubes in a one-to-one manner. There is one distribution tube in the top layer, and the feed port is connected to the feed tube. There are multiple balancing tubes, and the middle part is connected to the discharge port of the bottom layer distribution tube in a one-to-one manner. Both ends of the balancing tube are arranged lower than the middle part of the balancing tube. The multiple balancing tubes correspond to the multiple rows of distribution tubes in a one-to-one manner, and each row of distribution tubes is connected to the corresponding balancing tube.

[0010] By adopting the above technical scheme, the bulk material in the feed pipe flows layer by layer along more than two layers of distribution pipes. Since the discharge amount of the two discharge ports of each distribution pipe is consistent, the bulk material can achieve flow distribution after flowing through the distribution pipe, and since the distribution pipe evenly distributes the material, the bulk material can always be in a uniform flow state when flowing in more than two layers of distribution pipes, so that the bulk material can flow evenly into each distribution pipe. Since both ends of the distribution pipe are lower than the middle, when the discharge pipe is closed, the bulk material flowing in from the middle of the distribution pipe can preferentially flow to the two ends of the distribution pipe, and the bulk material can gradually accumulate from both ends of the distribution pipe to the middle, so that the bulk material can flow evenly to each discharge pipe, and it is not easy for the bulk material to leave dead corners in all distribution pipes and all distribution pipes.

[0011] Optionally, the material control component includes a sealing strip, a plurality of sealing strips are provided, and they correspond one-to-one to the plurality of rows of feeding pipes, the sealing strip cover is arranged at the pipe opening of the corresponding row of feeding pipes, and the sealing strip is slidably connected to the discharge pipe.

[0012] By adopting the above technical solution, a row of discharge pipes can be opened or closed synchronously by sliding the sealing strip, which makes it easier to close and open the discharge pipes and improves the efficiency of closing or opening all the discharge pipes.

[0013] Optionally, the loading tube rack is elastically slidably connected to the support frame in the vertical direction, and all the sealing strips are fixed by connecting rods to form at least one sealing structure. The material control assembly also includes a first telescopic rod, and the first telescopic rod is provided with at least one group, and corresponds one to one with the sealing structure formed by the sealing strips. There is at least one first telescopic rod in each group, and the first telescopic rod is fixedly connected to the material equalizing tube. The movable end of the first telescopic rod is fixedly connected with a material control block, and is fixedly connected to the sealing structure formed by the corresponding sealing strips. The material control block is fitted with the support frame, and the first telescopic rod drives the material control block to abut against the support frame by the gravity of the bulk material in the material equalizing tube. When the bulk material accumulates in the feeding pipe, the first telescopic rod drives the material control block to slide into the makeshift groove opened on the support frame.

[0014] By adopting the above technical solution, when the sealing strip closes the discharge pipe, the bulk material can be accumulated in the loading pipe rack, so that the overall weight of the loading pipe rack increases, and the loading pipe rack elastically slides down under the action of the increased gravity. During the sliding process, the first telescopic rod can drive the material control block to abut against the support frame with the help of the gravity of the bulk material in the material equalizing pipe. Since the first telescopic rod is difficult to extend, the sealing strip can always close the discharge pipe before the bulk material accumulates in the feed pipe, so that the bulk material is always in an accumulation state.

[0015] When bulk material accumulates at the feed pipe, the loading pipe rack carrying the first telescopic rod slides down to the make way slot, leaving space for the first telescopic rod to extend, so that the first telescopic rod can drive the material control block to be inserted into the make way slot, and the first telescopic rod also drives the sealing structure formed by its corresponding sealing strip to slide, so that all the discharge pipes closed by the sealing structure are opened, so that the sealing strip can automatically open the discharge pipe through the first telescopic rod when bulk material accumulates at the feed pipe.

[0016] Optionally, the first telescopic rod is connected to the second telescopic rod, the rodless cavity of the first telescopic rod and the rodless cavity of the second telescopic rod are both sealed and connected, a fluid medium flows between the rodless cavity of the first telescopic rod and the rodless cavity of the second telescopic rod, the second telescopic rod is fixed on the sealed end of the sliding tube connected to the end of the material equalizing tube, the movable end of the second telescopic rod slides into the sliding tube and is fixedly connected with a control plate, the control plate is adapted to the sliding tube, an elastic rubber block is arranged between the control plate and the sealed end of the sliding tube, and the elastic rubber block is used to drive the movable end of the second telescopic rod to extend.

[0017] By adopting the above technical scheme, when bulk material accumulates in the material balancing tube, the bulk material is squeezed on the control plate by gravity, so that the control plate has a tendency to slide, and when the material control block is opposite to the clearance groove, there is space for the first telescopic rod to extend, and the control plate drives the second telescopic rod to contract under the squeezing of the bulk material, and causes the elastic rubber block to accumulate elastic force, and the second contraction rod squeezes the fluid medium in its own rodless cavity into the rodless cavity of the first telescopic rod to drive the first telescopic rod to extend, so that the first telescopic rod can drive the material control block to abut against the support frame with the help of the gravity of the bulk material in the material balancing tube, and when the material control block is opposite to the clearance groove, the first telescopic rod can drive the material control block to be inserted into the clearance groove under the drive of the second telescopic rod.

[0018] When the bulk material in the material balancing pipe gradually decreases, the squeezing force of the bulk material on the control panel also gradually decreases. Therefore, when the bulk material is loaded onto the truck, the elastic rubber block can drive the control panel to slide in the opposite direction to drive the second telescopic rod to extend. The second telescopic rod drives the first telescopic rod to contract through the fluid medium. The first telescopic rod drives its corresponding sealing structure to close the discharge pipe, so that the sealing strip can automatically close the discharge pipe when the loading is completed, so as to facilitate the loading of the next truck.

[0019] Optionally, the rodless cavity of the first telescopic rod and the rodless cavity of the second telescopic rod are connected through a capillary damping tube, and the fluid medium flowing through the capillary damping tube is damping oil.

[0020] By adopting the above technical solution, the damping oil flows slowly in the capillary damping tube and can play a damping role, so that the mutual driving process between the first telescopic rod and the second telescopic rod is slow. Therefore, when the elastic rubber block drives the second telescopic rod to extend, under the damping effect formed by the damping oil and the capillary damping tube, the extension process of the second telescopic rod is prolonged, and the contraction process of the first telescopic rod is also prolonged, thereby making it easy to load all the residual bulk materials in the material equalizing tube into the truck bed, so that the loading accuracy of the bulk materials is not easily affected.

[0021] Optionally, all of the distribution pipes are commonly provided with an anti-blocking component, which includes a slide seat, a pull rope, a guide block and an anti-blocking shaft. There are multiple slide seats, and all are fixedly connected to the inner wall of the distribution pipe. The multiple slide seats are arranged in sequence along the side walls of the overall channel formed by the multiple layers of distribution pipes. The pull rope is annular and slidably passes through all the slide seats. There are multiple guide blocks, and they are fixed on the pull rope one by one along the extension direction of the pull rope. The anti-blocking shaft is rotatably provided in one of the distribution pipes. The pull rope part is wound around the anti-blocking shaft, and the whole is in a tensioned state.

[0022] By adopting the above technical solution, the pull rope can be driven to slide relative to the slide seat by rotating the anti-blocking shaft, the pull rope can drive the guide block to move, and the guide block can clear the bulk material in the distribution pipe, so that the bulk material in the distribution pipe is not easily blocked when it flows densely.

[0023] Optionally, one end of the anti-blocking shaft rotates to pass through the distribution pipe and is coaxially fixed with a gear. The anti-blocking component also includes a pneumatic vibrator, which is fixed on one of the distribution pipes and connected to an air compressor. The vibration shaft of the pneumatic vibrator is parallel to the anti-blocking shaft. The vibration shaft of the pneumatic vibrator is connected to a connecting rod. The middle part of the connecting rod is fixedly connected to the vibration shaft of the pneumatic vibrator. The two ends of the connecting rod are respectively fixedly connected with a first rack and a second rack. The first rack and the second rack are both bent in a circular arc shape. The first rack is used to engage with the inside of the gear, and the second rack is used to engage with the outside of the gear.

[0024] By adopting the above technical solution, high-pressure air is supplied to the pneumatic vibrator through an air compressor so that the pneumatic vibrator can vibrate. The pneumatic vibrator causes the material distribution pipe and the material equalization pipe to vibrate, which further makes the material distribution pipe and the material equalization pipe less likely to be blocked; when the pneumatic vibrator vibrates, it can drive the connecting rod to rotate through its own vibration shaft, and the connecting rod drives the first rack and the second rack to alternately mesh with the gear, and the first rack and the second rack cause the gear to rotate alternately forward and reverse, so that the pneumatic vibrator can not only vibrate the loading pipe rack, but also drive the guide block to clear the bulk material.

[0025] Optionally, the air compressor is electrically connected to a button, which is embedded in the bottom of the make way slot. When the first telescopic rod drives the material control block to slide into the make way slot, the material control block is squeezed on the button. When the button is pressed, the air compressor starts.

[0026] By adopting the above technical solution, when the material control block is inserted into the give way groove, the first telescopic rod not only drives the sealing strip to open the discharge pipe, but also can start the air compressor by squeezing the button, so that the vibration of the pneumatic vibrator can automatically cooperate with the falling of the discharge pipe.

[0027] Optionally, the unloading assembly includes a unloading pipe connected to the side wall of the silo and arranged vertically downwardly, an electric valve is provided on the unloading pipe, and the pipe is connected to a chute scale, the chute scale is connected to a dust suppression hopper, and the dust suppression hopper is opposite to the feed pipe.

[0028] By adopting the above technical solution, bulk materials are measured by a chute scale and transferred to a feed pipe by a dust suppression hopper, so that the loading of bulk materials is easy and accurate, and the bulk materials are not easy to generate dust during loading, so that the loading system can be used in places with high environmental protection requirements, such as ports.

[0029] In summary, the present application includes at least one of the following beneficial technical effects: 1. By providing a feed pipe, a loading pipe rack, a discharge pipe, a sealing strip and a first telescopic rod, the bulk material can flow evenly and densely to each discharge pipe, and continuously, stably and densely drop from each discharge pipe into the truck bed, so that the bulk material can be directly and evenly loaded into the truck bed, thereby improving the bulk material loading efficiency; 2. By arranging the second telescopic rod, the control panel, the elastic rubber block and the capillary damping tube, the first telescopic rod can drive the material control block to abut against the support frame by the gravity of the bulk material in the material distribution pipe, so that the sealing strip can automatically open the discharge pipe when the bulk material accumulates at the feed pipe; 3. By setting the slide seat, pull rope, guide block, anti-blocking shaft and pneumatic vibrator, the bulk material in the distribution pipe and the equalizing pipe is not easy to be blocked during the dense flow process.

[0033] The present application embodiment discloses a bulk material uniform loading system for the silo side wall. Figure 1 A bulk material uniform loading system for a silo side wall is used for transferring bulk material from a silo to a truck bed, and comprises a loading component 1, a discharge component 2 and a control component 3. The loading component 1 is arranged on the ground, the discharge component 2 is arranged between the loading component 1 and the silo side wall, and is used for flowing bulk material in the silo to the loading component 1, the loading component 1 is used for dropping material into the truck bed, the control component 3 is arranged on the loading component 1, and the control component 3 is used for controlling the timing of dropping material from the loading component 1 so that the loading component 1 drops material uniformly into the truck bed.

[0034] When in use, the bulk material in the silo flows to the loading component 1 through the unloading component 2, and the material control component 3 controls the material dropping timing of the loading component 1, so that the bulk material of the loading component 1 is evenly dropped into the truck bed, so that the bulk material can be directly and evenly loaded into the truck bed, thereby improving the bulk material loading efficiency.

[0035] Reference Figure 1 The unloading assembly 2 includes a unloading pipe 21, an electric valve 22, a chute scale 23 and a dust suppression hopper 24. The unloading pipe 21 is in the shape of a rectangular tube.

The unloading pipe 21 is arranged vertically downward, and the electric valve 22 is arranged on the unloading pipe 21. The discharge end of the chute scale 23 is connected to the dust suppression hopper 24. The chute scale 23 is used to measure the loading weight of bulk materials, and the dust suppression hopper 24 is used to limit dust dispersion when bulk materials are loaded.

[0036] The chute scale 23 accurately measures the loading weight of the bulk material in a continuous metering manner, thereby improving the loading accuracy of the bulk material and eliminating the need for over-unloading and under-filling; the dust suppression hopper 24 suppresses the flying dust during the loading of the bulk material, making it easier for the loading system to comply with environmental protection standards, and eliminating the need for additional dust removal equipment, thereby reducing the use of auxiliary electrical and mechanical equipment and reducing energy consumption during the loading process.

[0037] A material level sensor can be added at the feeding end of the dust suppression hopper 24 to monitor the overflow state of bulk material in the dust suppression hopper 24. The material level sensor can be electrically connected to the electric valve 22 through a controller. When the bulk material is overflowing, the material level sensor controls the electric valve 22 to close through the controller to protect the metering accuracy of the chute scale 23.

[0038] The chute scale 23 is electrically connected to a host computer, which is provided with a computing system for measuring bulk material weight and a production system for controlling production plans. The computing system of the host computer is associated with the production system data. The computing system can automatically change the adjustment coefficient of bulk material weight calculation according to the type of bulk material in the production system to improve the loading accuracy.

A telescopic rod 32 drives the material control block 321 to abut against the support frame 14 until the material control block 321 slides to the make way groove 141. At this time, the bulk material accumulates at the feed pipe 11. The first telescopic rod 32 drives the material control block 321 to be inserted into the make way groove 141 under the drive of the second telescopic rod 33, and drives the sealing strip 31 to open the discharge pipe 13. The bulk material falls continuously, stably and evenly from the discharge pipe 13 into the truck bed in a dense state, so that the bulk material can be directly and evenly loaded into the truck bed, thereby improving the bulk material loading efficiency.

[0053] When the loading weight of the bulk material reaches the preset weight, the electric valve 22 closes the discharge pipe 21, and the material level of the bulk material in the feed pipe 11, the distribution pipe 121 and the equalizing pipe 122 gradually decreases, and the elastic rubber block 35 drives the control plate 34 to slide in the opposite direction through the elastic force, so that the second telescopic rod 33 extends, and the second telescopic rod 33 drives the first telescopic rod 32 to contract through the capillary damping tube 331 and the damping oil. Under the damping action of the capillary damping tube 331 and the damping oil, the first telescopic rod 32 slowly drives the control block 321 to slide out of the clearance groove 141, so that the bulk material in the distribution pipe 121, the equalizing pipe 122 and the discharge pipe 13 can all be dropped into the truck bed. After the control block 321 slides out of the clearance groove 141, the first telescopic rod 32 drives the sealing strip 31 to re-close the discharge pipe 13, and the spring 124 drives the slider 123 to reset through the elastic force.

The part of the pull rope 42 close to the anti-blocking shaft 44 is wound around the anti-blocking shaft 44, and the pull rope 42 is in a tensioned state as a whole.

[0056] Reference Figure 2 The pneumatic vibrator 45 is fixed on one of the material distribution pipes 121 and is connected to an air compressor 46 . The air compressor 46 is fixed on the support frame 14 and is used to provide high-pressure air to the pneumatic vibrator 45 .

[0057] Reference Figure 6One end of the anti-blocking shaft 44 rotates and passes through the material distribution pipe 121, and is coaxially fixed with a gear 441. The vibration shaft of the pneumatic vibrator 45 is parallel to the anti-blocking shaft 44, and the vibration shaft of the pneumatic vibrator 45 is connected with a connecting rod 47. The connecting rod 47 is in a rectangular rod shape, and the middle part is fixedly connected to the vibration shaft of the pneumatic vibrator 45. The two ends of the connecting rod 47 are respectively fixedly connected with a first rack 48 and a second rack 49. The first rack 48 and the second rack 49 are both curved in an arc shape. The first rack 48 is used to mesh with the gear 441 internally, and the second rack 49 is used to mesh with the gear 441 externally.

[0058] Reference Figure 2 and Figure 5 The air compressor 46 is electrically connected to a button 461, which is embedded in the bottom of the make way slot 141. When the first telescopic rod 32 drives the material control block 321 to slide into the make way slot 141, the material control block 321 is pressed against the button 461. When the button 461 is pressed, the air compressor 46 starts.

[0059] When in use, the material control block 321 is inserted into the give way slot 141 and squeezed on the button 461, and the button 461 starts the air compressor 46, and the air compressor 46 drives the pneumatic vibrator 45 to vibrate, and the pneumatic vibrator 45 makes the first rack 48 and the second rack 49 alternately mesh with the gear 441 through the connecting rod 47, and the first rack 48 and the second rack 49 alternately drive the gear 441 to reciprocate, and the gear 441 drives the anti-blocking shaft 44 to reciprocate, and the anti-blocking shaft 44 drives the pull rope 42 to slide back and forth, and the pull rope 42 drives the dredging block 43 to dredge the distribution pipe 121, so that the distribution pipe 121 and the equalizing pipe 122 are not easily blocked.

[0060] The implementation principle of a system for uniformly loading bulk materials on the side wall of a silo in an embodiment of the present application is as follows: when in use, the truck is moved into the truck moving channel of the support frame 14, and the bulk material in the silo flows into the feed pipe 11 through the discharge pipe 21, the chute scale 23 and the dust suppression hopper 24, and the bulk material flows from the feed pipe 11 into the loading pipe rack 12, and flows evenly to each discharge pipe 13 through the loading pipe rack 12, and under the condition that the sealing strip 31 closes the discharge pipe 13, the bulk material accumulates in the loading pipe rack 12, and under the action of the gravity of the bulk material, the loading pipe rack 12 slides down as a whole to make the discharge pipe 13 close to the truck bed.

[0061] The bulk material drives the second telescopic rod 33 to contract through gravity, and the elastic rubber block 35 accumulates elastic force. The second telescopic rod 33 drives the first telescopic rod 32 to extend through the capillary damping tube 331 and the damping oil. The first telescopic rod 32 drives the material control block 321 to abut against the support frame 14 until the material control block 321 slides to the make way groove 141. The first telescopic rod 32 drives the material control block 321 to insert into the make way groove 141, and drives the sealing strip 31 to open the discharge pipe 13. The bulk material continuously, stably and evenly falls from the discharge pipe 13 into the truck bed in a dense state, so that the bulk material can be directly and evenly loaded into the truck bed, thereby improving the bulk material loading efficiency.

[0062] When the material control block 321 is inserted into the give way slot 141, it is pressed on the button 461. The button 461 starts the air compressor 46. The air compressor 46 drives the pneumatic vibrator 45 to generate vibration. The pneumatic vibrator 45 drives the gear 441 to reciprocate alternately through the first rack 48 and the second rack 49. The gear 441 drives the anti-blocking shaft 44 to reciprocate. The anti-blocking shaft 44 drives the pull rope 42 to slide back and forth. The pull rope 42 drives the dredging block 43 to dredge the distribution pipe 121, so that the distribution pipe 121 and the material distribution pipe 122 are not easily blocked.
