Description

Technical Field

[0001] This utility model belongs to the field of transportation dust removal, and more specifically, it relates to a dustproof conveying device. Background Technology

[0002] In existing waste conveying technologies, fixed conveyors are often used to deliver waste to the collection port. This method limits the flexibility of equipment layout due to the single delivery point. Alternatively, movable conveying equipment with a movable discharge end can be used to expand the delivery range. However, during the movement of such equipment, the gap between the discharge end and the feed window of the collection chamber changes, causing dust to easily escape and pollute the environment. At the same time, the moving conveying channel often lacks effective guiding and limiting mechanisms, making it prone to shaking or deviation. This not only aggravates the wear of sealing components and affects the durability of the seal, but also poses a risk of collision with the structure of the collection chamber. Even if simple soft seals are used, they often age and crack quickly due to the movement and vibration of the channel, making it difficult to achieve a durable and effective dynamic seal. Ultimately, this results in poor dustproof performance, low reliability, and frequent maintenance of the overall equipment. Utility Model Content

[0003] The purpose of this utility model is to provide a dustproof conveying device to solve the technical problem that dust is easily emitted through the feed window of the collection chamber or storage silo during the process of transporting materials into the collection chamber or storage silo.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a dustproof conveying device, comprising: A conveying channel, wherein the discharge end of the conveying channel can move horizontally, and the direction of movement of the conveying channel is perpendicular to its own length direction; The material collection chamber has a feeding window, and the discharge end of the conveying channel extends into the material collection chamber through the feeding window; A dust shield is fitted around the outer periphery of the conveying channel near the discharge end, and the dust shield is located on the discharge side of the inlet window. The dust shield can always cover the inlet window during the movement of the conveying channel.

[0005] In one feasible implementation, a flexible sealing sleeve is provided at the part of the dust shield that contacts the conveying channel, and the flexible sealing sleeve is used to form a sealed connection between the dust shield and the conveying channel.

[0006] In one feasible implementation, the material collection chamber is further provided with a guiding mechanism, which includes a guide rail and a movable support. The guide rail extends along the moving direction of the conveying channel, and the bottom end of the movable support is adapted to guide the guide rail, while the top end is used to support the conveying channel.

[0007] In one feasible implementation, the movable support includes a support plate and a guide wheel. The top of the support plate is fixedly connected to the conveying channel, and the bottom is provided with a rotatable guide wheel. The guide wheel rolls along the moving direction of the conveying channel to adapt to the guide rail.

[0008] In one feasible implementation, the guide rail is a linear guide rail or an arc-shaped guide rail.

[0009] In one feasible implementation, a flexible sealing ring is provided on the outer periphery of the side of the dust shield facing the inner wall of the collection chamber, and the flexible sealing ring is made of felt or flexible rubber.

[0010] In one feasible implementation, the guide rail is disposed on the inner wall of the collection chamber and located below the feed window.

[0011] In one feasible implementation, the dust cover is made of rigid plastic.

[0012] In one feasible implementation, both ends of the guide rail are provided with limiting blocks, and the conveying channel moves between the two limiting blocks.

[0013] Compared with existing technologies, the advantages of the dustproof conveying equipment provided by this utility model are as follows: First, the discharge end of the conveying channel can move horizontally in the same direction as its length. In conjunction with the feed window of the collection chamber and the dust shield installed near the discharge end of the conveying channel, the dust shield always covers the feed window during the movement of the conveying channel. When the discharge end moves, the feed window is dynamically closed, which effectively prevents dust from escaping from the feed window. This helps to solve the problem of dust leakage and environmental pollution caused by the movement of the discharge end during material conveying.

[0014] Secondly, a flexible sealing sleeve is provided at the part where the dust shield contacts the conveying channel. As the dust shield moves with the conveying channel, the flexible sealing sleeve can elastically deform and tightly fit the surface of the conveying channel, realizing a dynamic sealing connection between the dust shield and the conveying channel to prevent dust from leaking from the gap between them. This can improve the problem of poor sealing and dust overflow caused by relative movement.

[0015] In addition, the guide rail extends along the moving direction of the conveying channel, the bottom end of the moving support part is adapted to the guide rail, and the top end supports the conveying channel. In coordination with the moving process of the conveying channel, the moving support part slides or rolls along the guide rail, realizing the stable guidance and support of the conveying channel. This achieves the technical effect of ensuring the smooth and accurate movement of the conveying channel, which helps to solve the problems of shaking, deviation or jamming that may occur during the movement of the conveying channel.

[0016] Furthermore, the mobile support unit includes a support plate and guide wheels. With the smooth surface of the guide rail, the guide wheels roll on the guide rail, achieving low-friction movement of the conveying channel, reducing motion resistance and wear. This helps to solve the problems of decreased durability and high maintenance costs caused by friction in long-term use of the mobile support unit.

[0017] The guide rails can be either linear or curved, depending on the movement path requirements of the conveying channel. Linear guide rails are used for linear movement, while curved guide rails can be used for curved movement. This allows the conveying channel to flexibly adapt to different collection chamber layouts and material distribution requirements, improving equipment applicability and space utilization efficiency.

[0018] The flexible sealing ring on the side of the dust shield facing the inner wall of the collecting chamber, in conjunction with the contact between the dust shield and the inner wall of the collecting chamber during the movement of the dust shield, can compress and fill the gaps, realizing a secondary seal of the feeding window, enhancing the overall dustproof effect, and thus further solving the problem of dust escaping from the tiny gaps between the dust shield and the inner wall of the collecting chamber.

[0019] The guide rail is located on the inner wall of the collection chamber and below the feed window. In conjunction with the guiding function of the moving support, the guide rail provides bottom support for the conveying channel, while avoiding interference with the dust shield or feed window. This achieves stable movement of the conveying channel and optimized spatial layout, reduces the space occupied by the equipment, improves the cleanliness of the collection chamber, and prevents dust or other foreign objects from adversely affecting the cooperation between the guide rail and the guide wheel.

[0020] The dust shield is made of rigid plastic, which is lightweight, wear-resistant, and not easily deformed. This ensures the long-term reliable use of the dust shield, maintains its sealing performance and service life, and reduces the burden on the conveyor channel. This solves the problem of the dust shield's dynamic sealing and dust prevention effect being affected by its weight, wear, or deformation.

[0021] Limiting blocks are provided at both ends of the guide rail, which can physically block the excessive movement of the moving support, thereby specifically limiting the movement range of the conveying channel and preventing the conveying channel from leaving the guide rail or colliding with the feed window of the collection chamber. This helps to solve the problem of mechanical damage or safety accidents that may occur at the end of the movement of the equipment. Attached Figure Description

[0027] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] In existing waste conveying technologies, fixed conveyors are often used to deliver waste materials directly to the collection port. This method limits the flexibility of equipment layout due to the single delivery point. Alternatively, movable conveying equipment with a movable discharge end can be used to expand the delivery range. However, during the movement of such equipment, the gap between the discharge end and the inlet window of the collection chamber changes, allowing dust to easily escape and causing environmental pollution. At the same time, the moving conveying channel often lacks effective guiding and limiting mechanisms, making it prone to shaking or deviation. This not only exacerbates the wear of sealing components and affects the durability of the seal, but also poses a risk of collision with the structure of the collection chamber. Even if simple soft seals are used, they often age and crack quickly due to the movement and vibration of the channel, making it difficult to achieve a durable and effective dynamic seal. Ultimately, this results in poor dust prevention, low reliability, and frequent maintenance of the overall equipment. In view of this, this application aims to solve the technical problem of dust escape caused by the falling of fragments in the collection chamber by installing a dust shield on the side of the conveying channel located in the collection chamber to prevent dust in the collection chamber from spreading outward.

[0029] Based on the above overall design concept, please refer to the following: Figures 1 to 2 The dustproof conveying equipment provided by this utility model will now be described. The dustproof conveying equipment includes a conveying channel 1, a collection chamber 2, and a dust shield 3. The discharge end of the conveying channel 1 can move horizontally, and the direction of movement of the conveying channel 1 is perpendicular to its own length direction. The collection chamber 2 has a feeding window 21, and the discharge end of the conveying channel 1 passes through the feeding window 21 and extends into the collection chamber 2. The dust shield 3 is sleeved on the outer periphery of the conveying channel 1 near the discharge end, and the dust shield 3 is located on the discharge side of the feeding window 21. The dust shield 3 can always cover the feeding window 21 during the movement of the conveying channel 1.

[0030] In this embodiment, the discharge end of the conveying channel 1 can move horizontally, and the direction of movement is consistent with its own length direction. In conjunction with the inlet window 21 of the collection chamber 2 and the dust shield 3 fitted on the conveying channel 1 near the discharge end, the dust shield 3 always covers the inlet window 21 during the movement of the conveying channel 1, and dynamically closes the inlet window 21 when the discharge end moves, thereby effectively preventing dust from escaping from the inlet window 21, so as to solve the problem of dust leakage and environmental pollution caused by the movement of the discharge end during the material conveying process.

[0031] A feasible implementation method is proposed, wherein a flexible sealing sleeve 31 is provided at the contact point between the dust shield 3 and the conveying channel 1. The flexible sealing sleeve 31 is used to form a sealed connection between the dust shield 3 and the conveying channel 1. With this configuration, the flexible sealing sleeve 31 at the contact point between the dust shield 3 and the conveying channel 1, in conjunction with the movement of the dust shield 3 along the conveying channel 1, allows the flexible sealing sleeve 31 to elastically deform and tightly fit the surface of the conveying channel 1, achieving a dynamic sealed connection between the dust shield 3 and the conveying channel 1. This prevents dust from leaking from the gap between them, thereby improving the problems of poor sealing and dust overflow caused by relative movement. In specific implementation of the above embodiment, the guide rail 41 extends along the moving direction of the conveying channel 1, the bottom end of the moving support part 42 is adapted to guide the guide rail 41, and the top end supports the conveying channel 1. In conjunction with the movement of the conveying channel 1, the moving support part 42 slides or rolls along the guide rail 41, achieving stable guidance and support for the conveying channel 1. This achieves the technical effect of ensuring the smooth and accurate movement of the conveying channel 1, which helps to solve the problems of shaking, deviation, or jamming that may occur during the movement of the conveying channel 1.

[0032] A feasible implementation method is proposed, wherein the material collection chamber 2 is further provided with a guiding mechanism 4, which includes a guide rail 41 and a movable support part 42. The guide rail 41 extends along the moving direction of the conveying channel 1, and the bottom end of the movable support part 42 is adapted to guide the guide rail 41, while the top end is used to support the conveying channel 1.

[0033] A feasible implementation method is proposed, in which the movable support part 42 includes a support plate and a guide wheel. The top of the support plate is fixedly connected to the conveying channel 1, and the bottom is provided with a rotatable guide wheel. The guide wheel rolls along the moving direction of the conveying channel 1 and adapts to the guide rail 41. By utilizing the smooth surface of the guide rail 41, the guide wheel rolls on the guide rail 41, achieving low-friction movement of the conveying channel 1, reducing movement resistance and wear. This helps to solve the problems of decreased durability and high maintenance costs of the movable support part 42 due to friction during long-term use.

[0034] A feasible implementation method is proposed, wherein the guide rail 41 is a linear guide rail or an arc-shaped guide rail. In this embodiment, the guide rail 41 is a linear guide rail or an arc-shaped guide rail, which is compatible with the movement path requirements of the conveying channel 1. The linear guide rail is used for linear movement, while the arc-shaped guide rail can be used for curved movement. This enables the conveying channel 1 to flexibly adapt to different layouts of the collection chamber 2 and material distribution requirements, thereby improving the applicability of the equipment and the efficiency of space utilization.

[0035] A feasible implementation method is proposed, wherein a flexible sealing ring 32 is provided on the outer periphery of the side of the dust shield 3 facing the inner wall of the collection chamber 2. The flexible sealing ring 32 is made of felt or flexible rubber. In this embodiment, the flexible sealing ring 32 provided on the side of the dust shield 3 facing the inner wall of the collection chamber 2, in conjunction with the contact between the dust shield 3 and the inner wall of the collection chamber 2 during the movement of the dust shield 3, can compress and fill the gaps, realizing a secondary seal of the feed window 21, enhancing the overall dustproof effect, and thus further solving the problem of dust escaping from the tiny gaps between the dust shield 3 and the inner wall of the collection chamber 2.

[0036] A feasible implementation method is proposed, in which the guide rail 41 is disposed on the inner wall of the collection chamber 2 and located below the feed window 21. In conjunction with the guiding function of the movable support 42, the guide rail 41 provides bottom support for the conveying channel 1, while avoiding interference with the dust shield 3 or the feed window 21. This achieves stable movement of the conveying channel 1 and optimized spatial layout, reduces equipment space occupation, improves the cleanliness of the collection chamber 2, and prevents dust or other foreign objects from adversely affecting the cooperation between the guide rail 41 and the guide wheels.

[0037] A feasible implementation method is proposed, wherein the dust shield 3 is made of rigid plastic. Rigid plastic has the characteristics of being lightweight, wear-resistant, and not easily deformed, which enables the long-term reliable use of the dust shield 3, maintains the sealing performance and service life, and reduces the burden of the dust shield 3 on the conveying channel 1, thereby solving the problem that the dynamic sealing and dust prevention effect of the dust shield 3 is affected by its weight, wear, or deformation.

[0038] A feasible implementation method is proposed, wherein both ends of the guide rail 41 are provided with limiting blocks, and the conveying channel 1 moves between the two limiting blocks. The limiting blocks at both ends of the guide rail 41 can physically block the excessive movement of the moving support part 42, thereby specifically limiting the movement range of the conveying channel 1 and preventing the conveying channel 1 from leaving the guide rail 41 or colliding with the feed window 21 of the collection chamber 2, which helps to solve the problem of mechanical damage or safety accidents that may occur at the end of the movement of the equipment.

[0039] In summary, compared with the prior art, the dust-proof conveying equipment in this application, through a series of innovative structural designs, comprehensively solves the core problems of dust dispersion, poor equipment flexibility and low operational reliability in the existing waste conveying process, bringing significant technological progress and beneficial effects.

[0040] First, the most significant benefit of this equipment lies in achieving highly efficient dynamic sealing during the moving discharge process. By enabling the discharge end of the conveying channel 1 to move horizontally and cleverly incorporating a movable dust shield 3 onto the channel, the dust shield 3 continuously shields the feed window 21 of the collection chamber 2 throughout the entire moving stroke. This design fundamentally cuts off the main channel for dust to escape, achieving a leap from "static partial sealing" to "dynamic full-process sealing" compared to traditional fixed or simple moving conveyors, thus improving the cleanliness of the working environment and effectively solving the key technical problems of dust pollution and material loss. Second, the equipment improves the stability and accuracy of the moving process of the conveying channel 1 by introducing a guiding mechanism 4. The guiding system, consisting of the guide rail 41 and the moving support 42 (especially using a combination of support plate and guide wheel), provides stable, low-friction support and guidance for the conveying channel 1. This not only ensures the stability of the relative position between the dust shield 3 and the feed window 21, thus maintaining a continuous sealing effect, but also avoids possible shaking, jamming, or displacement of the channel during movement, ensuring smooth and reliable equipment operation and extending its service life. Third, the equipment constructs a multi-layered, synergistic sealing system consisting of three key sealing points: First, the dust shield 3 itself acts as the main barrier, continuously shielding the large feed window 21; second, the dust shield 3 is connected to the conveying channel 1 via a flexible sealing sleeve 31, achieving a tight dynamic seal between moving parts and compensating for manufacturing and assembly errors; third, the flexible sealing ring 32 (such as felt or rubber) on the outer periphery of the dust shield 3 forms a secondary seal with the inner wall of the collection chamber 2, further sealing minor gaps. These three seals work together to form a three-dimensional, reliable dustproof system, ensuring that dust cannot penetrate even during long-term operation and movement. Furthermore, the design of this utility model also demonstrates excellent adaptability and safety. By using straight or curved guide rails, the equipment can flexibly adapt to different site layouts and process requirements. Meanwhile, the limiting blocks at both ends of the guide rail 41 provide physical hard limits on the movement range of the conveying channel 1, effectively preventing equipment collisions and damage that may occur due to overtravel, and improving the overall operational safety. In summary, the dustproof conveying equipment of this patent successfully integrates dynamic sealing technology, a stable guiding system, and multiple sealing strategies, not only excellently solving the core problem of dust dispersion, but also simultaneously improving the equipment's operational stability, environmental adaptability, and safety reliability. It is an innovative design with significant environmental benefits and practical value.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
