Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a chute-type material discharge device. Background Technology

[0002] Currently, in the photovoltaic glass manufacturing industry, the most common method for homogenizing quartz sand in a homogenization silo is as follows: First, a bucket elevator lifts the quartz sand to a height above the top of the homogenization silo via a conveyor belt. Then, a chute diverts the quartz sand from the bucket elevator outlet onto the conveyor belt, where it is stacked at any location within the silo. Finally, gravity equalizes the moisture content of the quartz sand, completing the homogenization process. Typically, to increase the quartz sand conveying capacity and save on project investment and operating costs, most designs use two bucket elevators to feed one conveyor belt. This reduces the purchase and operating costs of one conveyor belt without reducing the overall conveying capacity.

[0003] However, in order to prevent material accumulation, existing chutes usually need to ensure that the angle between the installation angle of the chute and the horizontal plane is ≥65°. Therefore, the drop between the bucket elevator and the cloth conveyor needs to reach about 6 meters, which puts forward higher requirements for plant construction, equipment installation and maintenance.

[0004] Therefore, there is an urgent need for a chute-type material feeding device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a chute-type material feeding device that can reduce the requirements for factory construction, equipment installation, and equipment maintenance.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A chute-type material feeding device includes:

[0008] A dual-channel conveying pipe has a first inlet, a second inlet, and an outlet. The first inlet and the second inlet are located above the outlet. A first channel is formed between the first inlet and the outlet, and a second channel is formed between the second inlet and the outlet. The first channel and the second channel are connected at the outlet and configured as a mixing section.

[0009] A valve plate is disposed within the mixing section. The valve plate is used to block the material within the mixing section so that the material is uniformly distributed or normally distributed along a first horizontal direction when it leaves the discharge port.

[0010] Preferably, the dual-channel conveying pipe includes a first sluice, a second sluice, and a mixing pipe. The first inlet is located at the top of the first sluice, the second inlet is located at the top of the second sluice, and the outlet is located at the bottom of the mixing pipe. Both the first and second sluices are inclined.

[0011] The first chute and the mixing tube are connected and define the first channel, the second chute and the mixing tube are connected and define the second channel, and the mixing section is formed inside the mixing tube.

[0012] Preferably, the first channel and the second channel are arranged symmetrically about the axis of the discharge port, and the valve plate is adjustable in position in the vertical direction within the mixing section and coincides with the axis of the discharge port.

[0013] Preferably, the inner wall of the mixing section is provided with a protrusion, and the protrusion is provided with a mounting groove in the vertical direction, and the valve plate is inserted and installed in the mounting groove.

[0014] Preferably, the dual-channel conveying pipe is also fixedly provided with a bracket, and an adjusting rod is passed through the bracket. The adjusting rod is adjustable in position along the vertical direction, and the bottom end of the adjusting rod is connected to the valve plate.

[0015] Preferably, the adjusting rod is threaded with at least two nuts, one of which is located above the bracket and the other is located below the bracket, with the two nuts clamping the bracket.

[0016] Preferably, the bracket is provided with two adjusting rods, which are spaced apart and both are connected to the valve plate.

[0017] Preferably, a conveyor belt is provided below the chute-type material discharge device, and the material falls onto the conveyor belt after leaving the discharge port. The conveyor belt is used to transport the material along the second horizontal direction, and the first horizontal direction and the second horizontal direction are arranged perpendicular to each other.

[0018] Preferably, polyethylene plates are provided on both sides of the valve plate, and the thickness of the polyethylene plate on each side is not less than 15mm.

[0019] Preferably, the vertical distance between the first feed inlet and the second feed inlet and the discharge outlet is no more than 3m.

[0020] The beneficial effects of this invention are as follows: In this chute-type material feeding device, whether materials are simultaneously input through the first and second inlets or only through one of them, the movement trajectory of a portion of the material can be altered by blocking a portion of it through the valve plate. This ensures that when the material is output from the outlet, it is evenly or normally distributed along the first horizontal direction, thus preventing material concentration at the edge of the conveyor belt. Furthermore, compared to a Y-shaped structure, it reduces the required installation height, lowers the requirements for factory construction and equipment installation, and facilitates installation and maintenance, thereby avoiding higher installation and maintenance costs.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," and "abutting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] like Figure 1As shown, in the prior art, two chutes and an output pipe 100' are connected in a Y-shape. Each of the two chutes is connected to a hopper 22, which can respectively receive material from one bucket elevator and finally output it to the conveyor belt 41 of the belt conveyor through the output pipe 100'. The output pipe 100' is relatively long, so that the material can change its trajectory by impacting the inner wall of the output pipe 100' when entering and passing through it. In this way, regardless of whether the two bucket elevators are running simultaneously, the material can fall evenly into the middle of the conveyor belt 41 after passing through the output pipe 100', avoiding material deviation along the first horizontal direction and concentration at the edge of the conveyor belt 41. The conveyor belt 41 transports material along the second horizontal direction (the second horizontal direction is perpendicular to the first horizontal direction). When the material is concentrated at the edge of the conveyor belt 41, the conveyor belt 41 will deviate. However, the output pipe 100' requires a considerable amount of height for installation, which results in a final drop h0 between the bucket elevator and the conveyor belt 41 of about 6m, placing higher demands on the construction of the plant and the installation and maintenance of the equipment.

[0040] The following is based on the appendix Figure 2 To be continued Figure 7 This invention introduces a chute-type material discharge device. This chute-type material discharge device can reduce the required installation height, thereby avoiding high installation and maintenance costs.

[0041] Specifically, such as Figure 2 , Figure 3 As shown, in this embodiment, the chute-type material discharge device includes a dual-channel conveying pipe and a valve plate 34. The dual-channel conveying pipe has a first inlet, a second inlet, and an outlet. The first and second inlets are horizontally spaced apart and both are positioned above the outlet, forming a V-shape. In this chute-type material discharge device, a first channel 101 is formed between the first inlet and the outlet, and a second channel 102 is formed between the second inlet and the outlet. The first channel 101 and the second channel 102 are connected at the outlet. For ease of explanation, the connected portion is defined as the mixing section 103. That is, when materials simultaneously enter the chute-type material discharge device from the first and second inlets, they will mix in the mixing section 103 before flowing out from the outlet.

[0042] Valve plate 34 is fixedly installed inside the mixing section 103 and can block the material flowing through the mixing section 103, so that the material is evenly or normally distributed along the first horizontal direction (i.e., the direction from the middle position to the edge position of the conveyor belt 41) when leaving the discharge port. At this time, it is only necessary to reasonably set the position of the conveyor belt 41 along the first horizontal direction so that the conveyor belt 41 is directly below the discharge port, which can prevent the material from concentrating at the edge position of the conveyor belt 41 and causing deviation.

[0043] It is important to emphasize that in this chute-type material feeding device, whether material is input simultaneously through the first and second inlets or only through one of them, the valve plate 34 can partially obstruct the material's movement trajectory, thus ensuring that the material is evenly or normally distributed along the horizontal first direction when it exits the outlet, preventing material concentration at the edge of the conveyor belt 41. Furthermore, compared to a Y-shaped structure, this reduces the required installation height, lowers the requirements for plant construction and equipment installation, and facilitates installation and maintenance, thereby avoiding higher installation and maintenance costs. For example, in this embodiment, the vertical distance between either the first or second inlet and the outlet is no more than 3 meters.

[0044] Specifically, such as Figure 2 , Figure 3 As shown, in this embodiment, the dual-channel conveying pipe includes a first chute 11, a second chute 12, and a mixing pipe 13. A first inlet is located at the top of the first chute 11, and a connecting flange 21 is connected to the first inlet. The bottom end of the connecting flange 21 is fixed to the first chute 11 with bolts, and a hopper 22 is connected to the top of the connecting flange 21, facilitating the bucket elevator to input material into the first chute 11. Similarly, a second inlet is located at the top of the second chute 12, and a connecting flange 21 is also connected to the second inlet, with a hopper 22 also connected to the top of the connecting flange 21, facilitating the bucket elevator to input material into the second chute 12. The mixing pipe 13 has a V-shaped structure, with two connection ports and the aforementioned discharge port. One connection port is connected to the bottom end of the first chute 11, and the other connection port is connected to the bottom end of the second chute 12. After the first chute 11 and the mixing pipe 13 are connected, a first channel 101 is formed. After the second chute 12 and the mixing pipe 13 are connected, a second channel 102 is formed. A mixing section 103 is formed inside the mixing pipe 13. Both the first chute 11 and the second chute 12 are inclined and form an angle b of at least 65° with the horizontal plane to avoid material accumulation. Preferably, the height distance h1 between the discharge port and any of the connecting flanges 21 is not greater than 3m.

[0045] Preferably, the first channel 101 and the second channel 102 are symmetrically arranged about the axis of the discharge port. The valve plate 34 is vertically adjustable and arranged in the mixing section 103, coinciding with the axis of the discharge port. After flowing through the first channel 101 and the second channel 102, the material flows into the mixing section 103 and impacts the surface of the valve plate 34. At this time, the movement trajectory of the material flowing through the first channel 101 and the movement trajectory of the material flowing through the second channel 102 are also symmetrically arranged about the axis of the discharge port. This allows the operator to easily find the setting position that simultaneously satisfies the above-mentioned simultaneous material input and selective material input by simply adjusting the installation position of the valve plate 34 in the vertical direction. This ensures that whether the material is input through the first and second inlets simultaneously or only one of the first and second inlets, the movement trajectory of the material can be changed by partially blocking a portion of the material through the valve plate 34. This results in the material being uniformly or normally distributed along the first horizontal direction when it is discharged from the discharge port.

[0046] Optionally, such as Figure 3 , Figure 4 As shown, in this embodiment, the inner wall of the mixing section 103 is provided with a protrusion 35, and the protrusion 35 is provided with an installation groove 131 in the vertical direction. The end of the valve plate 34 is inserted into the installation groove 131. On the one hand, the protrusion 35 can guide the movement direction of the valve plate 34 when the operator adjusts the installation position of the valve plate 34, reducing the difficulty of adjustment. On the other hand, when the valve plate 34 blocks the material, the side wall of the installation groove 131 can abut against the valve plate 34, thereby preventing the valve plate 34 from flipping or shifting under the impact of the material, ensuring that the valve plate 34 can be fixed in the preset position, and ensuring the effect of optimizing the distribution of the material. Of course, in some embodiments, the above-mentioned installation groove 131 can also be formed directly by cutting. Therefore, the forming method of the installation groove 131 is not limited in this utility model.

[0047] like Figure 5 As shown, in this embodiment, the valve plate 34 has a tongue-shaped structure, with the tip of the tongue-shaped structure facing the discharge port. This is because the first chute 11 and the second chute 12 are mostly circular pipes, so the material will concentrate at the bottom of the circular pipe. The tongue-shaped structure can utilize the limited area of ​​the valve plate 34 to block as much material as possible, achieving a higher material utilization rate and a better blocking and guiding effect.

[0048] Preferably, such as Figure 6 As shown, polyethylene plates 342 are provided on both sides of the valve plate 34, and the thickness of the polyethylene plate 342 on each side is not less than 15mm. The polyethylene plate 342 has excellent wear resistance and impact resistance, a low surface friction coefficient that prevents material from accumulating, and is suitable for high-wear environments that withstand long-term material impact. Optionally, such as... Figure 7 As shown, when the first chute 11 and the second chute 12 are square pipes, a square valve plate 34 can also be used to achieve a sufficient blocking effect.

[0049] Continue to refer to Figure 7 As shown, the mixing pipe 13 is also fixedly equipped with a bracket 31, and an adjusting rod 32 is threaded through the bracket 31. The adjusting rod 32 is adjustable in position along the vertical direction, and the bottom end of the adjusting rod 32 is connected to the valve plate 34. By moving the adjusting rod 32 in the vertical direction, the position of the valve plate 34 can be adjusted.

[0050] Specifically, the bracket 31 extends along a second horizontal direction, and each end of the bracket 31 has a mounting hole, through which an adjusting rod 32 passes. The two adjusting rods 32 are spaced apart, and their bottom ends are connected to the valve plate 34, thereby further improving the impact resistance of the valve plate 34 and making the valve plate 34 stable. The adjusting rods 32 have external threads, and each adjusting rod 32 is threaded with at least two nuts 33. When the adjusting rods 32 and the bracket 31 are fixed, one nut 33 is located above the bracket 31, and the other nut 33 is located below the bracket 31. The two nuts 33 clamp the bracket 31, thereby fixing the bracket 31, adjusting rods 32, and valve plate 34 together, improving the overall structural stability.

[0051] Preferably, refer to Figure 6 , Figure 7 As shown, each adjusting rod 32 has a plug-in hole at its bottom end. The valve plate 34 includes a plug plate 341 and the aforementioned polyethylene plate 342. The plug plate 341 has multiple connection holes for mounting the polyethylene plate 342. Simultaneously, each end of the plug plate 341 along the second horizontal direction has a plug-in portion 3411, which is plugged into the plug-in hole, thereby connecting the plug plate 341 and the two adjusting rods 32. This plug-in connection method simplifies installation and disassembly by requiring only operation on the adjusting rods 32, thus reducing maintenance costs. Optionally, the thickness of the plug plate 341 is not less than 10mm to provide sufficient structural strength.

[0052] Specifically, in one embodiment, three grooves with a width of 40mm can be cut along the central axis of the mixing pipe 13. These three grooves are located on the inner walls of both sides and the outer wall of the top of the mixing pipe 13. The two grooves on the inner walls form the aforementioned mounting grooves 131, while the groove on the outer wall is used to weld the connecting bracket 31. Then, the adjusting rod 32, nut 33, insert plate 341, polyethylene plate 342, and other components are assembled and installed one by one. Finally, the conveyor belt 41 is positioned below the chute-type discharge device, allowing for the adjustment of the valve plate 34's installation position.

[0053] Taking a GTD800 bucket elevator and two square chutes 11 and 12 with inner diameters of 400*400mm as examples, first adjust the bottom of the valve plate 34 to about 30mm from the surface of the conveyor belt 41, then start any bucket elevator to begin feeding. Then, adjust the height of the valve plate 34 according to the thickness of the material falling on the left and right sides of the conveyor belt 41. Adjusting it downwards will increase the material falling on the starting side and make the material layer thicker, while adjusting it upwards will increase the material falling on the stopping side and make the material layer thicker, until the thickness of the material falling on both sides is the same and symmetrically distributed in the center of the conveyor belt 41, thus completing the adjustment of the valve plate 34's installation position.

[0054] For example, since the conveyor belt 41 presents a symmetrical arc shape on the bracket, only the thickness of the material layer 20cm from the edge on both sides of the conveyor belt 41 can be measured to reflect whether the material distribution is uniform. When the data measured on both sides is 93mm, it is preliminarily determined that the appropriate installation position of the valve plate 34 has been reached. Trying to adjust the valve plate 34 down by 10mm, the material layer thickness on the start side increases to 99mm, and the material layer thickness on the stop side decreases to 47mm, resulting in uneven material distribution and a slight deviation of the conveyor belt 41. After the test, the valve plate 34 is readjusted back to its original height, so that the material layer is restored to 93mm. The quartz sand is redistributed evenly again, and the conveyor belt 41 does not deviate, confirming that this position is the correct installation position. Then, tighten the nut 33 on the adjusting rod 32 to fix the valve plate 34.

[0055] Similarly, taking the GTD800 bucket elevator and the circular first chute 11 and circular second chute 12 with an inner diameter of 400*400mm as examples, the thickness of the material layer 20cm from the edge on both sides of the conveyor belt 41 was measured. When the measured data on both sides was 76mm, it was initially determined that the appropriate installation position of the valve plate 34 had been reached. Trying to adjust the insert plate 341 downwards by 10mm increased the material layer thickness on the start-up side to 125mm and decreased it to 32mm on the stop-up side, resulting in uneven material distribution and significant belt misalignment on the conveyor belt 41. After the test, the valve plate 34 was readjusted back to its original height, restoring the material layer to 76mm. The quartz sand was redistributed evenly, and the conveyor belt 41 showed no misalignment, confirming that this position was the correct installation position. Then, the nut 33 on the adjusting rod 32 was tightened to fix the valve plate 34.
