Abstract
Description
Technical Field
[0001] This utility model belongs to the field of feeding pipe technology, specifically relating to a blower feeding pipe. Background Technology
[0002] In the production process, it is usually necessary to transport materials from low to high. Currently, in order to achieve the above technical effect, blowers and pipelines are usually coupled to form a conveying device, which pushes the materials in the pipeline to move under the action of wind force.
[0003] In conveying devices, elbows are pipe fittings that change the direction of material conveying. The impact force generated by material conveying will directly act on the inner wall of the elbow, which will not only exert a continuous impact force on the inner wall of the elbow, but also cause wear on the inner wall of the elbow. In severe cases, it will lead to deformation and damage of the elbow, which will directly affect the service life of the elbow.
[0004] In response, existing technologies often involve thickening the inner wall of the elbow where it contacts the material. However, this increases the manufacturing cost of the elbow and inevitably leads to wear and tear, eventually requiring replacement and disrupting the normal operation of the conveying device. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a blower feeding pipe to solve the technical problem that the existing technology cannot fundamentally reduce wear by simply thickening the part of the elbow inner wall that comes into contact with the material.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A blower feeding pipe includes a blower, a transition pipe, and a transport pipe connected in sequence. The transport pipe includes a horizontal section and an inclined section, which are connected by an elbow. A flow-dividing mechanism is provided inside the elbow. The inner wall of the elbow includes an outer bend side and an inner bend side, wherein the outer bend side refers to the side away from the bend center. The flow-dividing mechanism includes a flow-dividing plate with the bend degree consistent with the bend, which divides the internal space of the elbow into two parts. Relative limiting devices are provided on the inner wall of the elbow. The trough and the limiting trough are arc-shaped. The flow divider plate is adapted to the limiting trough and is slidably connected in the limiting trough. The flow divider plate and the limiting trough are elastically connected by a spring. A guide platform is provided in the horizontal section and at the bottom of the horizontal section. The guide platform is close to the flow divider plate. The guide platform is triangular and sloping. The sloping side facing the blower is the windward side. The ridge of the guide platform is located below the flow divider plate. The guide platform is hollow inside to form a receiving cavity. Multiple filter holes are opened on the windward side of the guide platform.
[0008] Furthermore, there is a gap between the two ends of the diverter plate and the end face of the limiting groove. A spring is installed in this gap. One end of the spring is fixedly connected to the end face of the diverter plate, and the other end of the spring is fixedly connected to the end face of the limiting groove.
[0009] Furthermore, the bottom surface of the guide platform is curved and contacts the inner wall of the horizontal section;
[0010] Furthermore, a wedge-shaped bevel is formed at one end of the diverter plate near the horizontal section;
[0011] Furthermore, heat dissipation fins are provided on the outer surface of the elbow corresponding to the outer bend side of the elbow;
[0012] Furthermore, the angle between the inclined section and the horizontal plane is 60°.
[0013] The beneficial effects of this utility model are as follows:
[0014] Compared to existing technologies, by incorporating a diversion mechanism, when material reaches the guide platform, it leaps across the windward side, with a portion landing on the upper surface of the diversion plate and the other on the outer curved side of the elbow. This fundamentally reduces the contact between the material and the outer curved side of the elbow, effectively reducing the impact force and wear on this side, thus achieving load sharing. Furthermore, when the diversion plate is impacted by material, it can slide within the limiting groove, with springs on both sides providing cushioning, further reducing the impact load on the diversion plate. Additionally, when the windward side of the guide platform contacts the material, dust and other minute impurities contained in the material pass through the filter holes into the receiving cavity, and can be discharged by opening the sealing screws, achieving dust removal by collecting these minute impurities.

[0024] Example 1, specifically as follows Figures 1-6 As shown.
[0025] A blower feeding pipe includes a blower 1, a transition pipe 2 and a transport pipe 3 connected in sequence. The transport pipe 3 includes a horizontal section 301 and an inclined section 302. The horizontal section 301 and the inclined section 302 are connected by an elbow 303. A diversion mechanism 4 is provided in the elbow 303.
[0026] like Figure 1 As shown, the transition pipe 2 is located between the blower 1 and the conveying pipe 3. The air outlet of the blower 1 is connected to the air inlet of the transition pipe 2. The end of the transition pipe 2 away from the blower 1 is tapered, which further increases the air velocity by reducing the cross-sectional area. The horizontal section 301 of the conveying pipe 3 is connected to the transition pipe 2. A hopper 304 is provided at the top of the horizontal section 301 near the transition pipe 2. The material enters the horizontal section 301 through the hopper 304. The air force generated by the blower 1 is further accelerated by the transition pipe 2 before entering the conveying pipe 3, which at the same time drives the material in the horizontal section 301 to move.
[0027] The inclined section 302 is used to cooperate with the wind to lift the material to a higher height. The angle between the inclined section 302 of the transport pipe 3 and the horizontal plane is 0-90°. In this embodiment, the angle between the inclined section 302 and the horizontal plane is 60°, which can effectively balance the conveying efficiency and the anti-blocking ability.
[0028] An elbow 303 is provided between the horizontal section 301 and the inclined section 302 to connect the two. The elbow 303 is curved, with one end fixedly and sealed to the horizontal section 301 and the other end fixedly and sealed to the inclined section 302. The connection between the two ends of the elbow 303 can be achieved by flange connection or welding. In this embodiment, the connection is achieved by welding to achieve a fixed and sealed connection.
[0029] The inner wall of elbow 303 includes an outer bending side and an inner bending side. The outer bending side is the side away from the bending center, which is frequently impacted by materials and experiences more severe wear. The inner bending side is the side closer to the bending center and experiences less wear. To address this, a flow-diverting mechanism 4 is installed inside elbow 303 to distribute the impact and friction experienced by the outer bending side, thereby reducing wear on the outer bending side.
[0030] like Figures 2-6 As shown, the diversion mechanism 4 includes a diversion plate 401 that matches the curvature of the elbow 303. The diversion plate 401 divides the internal space of the elbow 303 into two parts, including an inner flow space near the inner bend side and an outer flow space near the outer bend side. Specifically, the inner wall of the elbow 303 is provided with opposing limiting grooves 402. It is worth emphasizing that the limiting grooves 402 are generally arc-shaped. The diversion plate 401 is adapted to the limiting grooves 402, and the diversion plate 401 is slidably connected within the limiting grooves 402. It should be further explained that there is a gap between the two ends of the diverter plate 401 and the end face of the limiting groove 402. A spring 403 is provided in the gap. One end of the spring 403 is welded to the end face of the diverter plate 401, and the other end of the spring 403 is welded to the end face of the limiting groove 402. The diverter plate 401 and the limiting groove 402 are elastically connected by the spring 403. When the diverter plate 401 slides in the limiting groove 402, it can provide a buffering effect for the diverter plate 401.
[0031] A wedge-shaped bevel 404 is formed at one end of the flow divider 401 near the horizontal section 301. The bevel 404 increases the contact area and provides a transition for the material to contact the flow divider 401, thereby reducing the splashing caused by the collision between the material and the flow divider 401.
[0032] A guide platform 405 is provided within the horizontal section 401 and at its bottom. The guide platform 405 is close to the diverter plate 401. The guide platform 405 has a triangular sloping structure, with its sloping side facing the blower 1 being the windward side and its sloping side facing the guide platform 405 being the leeward side. The bottom surface of the guide platform 405 is curved and contacts the inner wall of the horizontal section 301. In this embodiment, the bottom surface of the guide platform 405 and the inner wall of the horizontal section 301 are fixedly connected by welding. It is worth noting that the ridge line of the guide platform 405 is located below the diverter plate 401.
[0033] The guide platform 405 is hollow inside to form a receiving cavity 406. Multiple filter holes 407 are opened on the windward surface of the guide platform 405. A vertical threaded hole is opened at the bottom of the guide platform 405. The threaded hole passes through the horizontal section 301, so that the receiving cavity 406 is connected to the external space. A sealing screw 408 is connected to the threaded hole.
[0034] In operation, the material moves along the transport pipe 3 under the influence of wind. When the material reaches the guide platform 405, it leaps due to the windward action. Part of it lands on the upper surface of the diversion plate 401, and the other part lands on the outer curved side of the elbow 303. This fundamentally reduces the contact between the material and the outer curved side of the elbow 303, effectively reducing the impact force and wear on the outer curved side, thus achieving load sharing. Furthermore, when the diversion plate 401 is impacted by the material, it can slide within the limiting groove 402 and be buffered by the springs 403 on both sides, reducing the impact load on the diversion plate 401 to a certain extent. In addition, when the windward side of the guide platform 405 contacts the material, the dust and other small impurities contained in the material pass through the filter holes 407 into the receiving cavity 406, and can be discharged by opening the sealing screws 408, thus collecting the small impurities and achieving a dust removal effect.
[0035] Furthermore, during continuous contact between the outer bend of elbow 303 and the material, the local temperature rises. When a certain temperature is reached, the material in contact with it may melt, thus affecting subsequent production. To address this, in this embodiment, heat dissipation fins 5 are provided on the outer surface of the elbow corresponding to the outer bend of elbow 303. The heat dissipation fins 5 are welded and fixed to the outer surface of elbow 303. The heat dissipation fins 5 accelerate heat dissipation at the outer bend of elbow 303, preventing the material from melting due to excessive temperature.
[0036] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
