Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology in mechanical engineering, and in particular to an adjustable chute used in the installation of conveying equipment. Background Technology

[0002] In bulk material conveying systems such as those for coal, grain, cement, and ore, chutes are crucial components connecting different equipment (e.g., conveyor heads and tails, dust collectors, silos, etc.) to guide material flow. Traditional chutes are mostly fixed structures, with the positions of their upper and lower flanges determined during manufacturing and cannot be adjusted. During actual installation, due to factors such as civil construction errors, equipment manufacturing tolerances, and cumulative installation errors, unavoidable misalignment (including horizontal center deviation and vertical height deviation) often occurs at the flange interfaces of upstream and downstream equipment. To connect and fix the chute, installers often need to resort to emergency measures such as forceful assembly, cutting, adding gaskets, or even modifying the equipment foundation. This not only results in extremely low installation efficiency and high labor intensity but also makes it difficult to guarantee the sealing and coaxiality of the connection, leading to a series of problems such as material leakage, increased equipment vibration, and accelerated wear. Therefore, there is an urgent need for a chute structure that can be flexibly and precisely adjusted on-site to compensate for installation errors and improve installation efficiency and system reliability. Summary of the Invention

[0003] The present invention aims to address the shortcomings of the prior art by providing an adjustable chute for use in conveying equipment installation.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable chute for installation in conveying equipment, comprising an upper flange connected to an upstream conveying device, a lower flange connected to a downstream conveying device, and a chute body connected between the upper flange and the lower flange. It also includes an adjustable connection structure, with an upper flat flange plate and a lower flat flange plate respectively provided at the top and bottom of the chute body. The upper flat flange plate is bolted to the bottom of the upper flange. The adjustable connection structure includes a horizontal adjustment flange plate and a vertical adjustment chute. The horizontal adjustment flange plate is adjusted and fixedly connected to the bottom of the lower flat flange plate in four directions (front, back, left, and right). The top of the vertical adjustment chute is fixedly connected to the horizontal adjustment flange plate, and its bottom is inserted into the lower flange, with a ring of sealant applied to the insertion gap between the vertical adjustment chute and the top of the lower flange.

[0005] Specifically, the upper flange and the lower flange are both rectangular frames, with the vertical cross-section of the upper flange side being C-shaped and the vertical cross-section of the lower flange side being L-shaped.

[0006] Specifically, a flat washer and a spring washer are installed at the bolt connection between the upper flat flange plate and the upper flange.

[0007] Specifically, the side width of the horizontal adjusting flange is smaller than that of the lower flat flange, and the adjustment range for forward, backward, left, and right movement is ±20mm. The horizontal adjusting flange is welded and fixed to the lower flat flange.

[0008] Specifically, the top of the vertical adjusting chute is connected to the inner ring side wall of the horizontal adjusting flange plate, and the connection is filled with sealant and spot welded. The vertical adjusting chute can be adjusted up and down within a range of ±50mm.

[0009] The beneficial effects of this utility model are:

[0010] Easy to install and highly forgiving: The horizontal adjustment flange plate enables ±20mm horizontal adjustment, and the vertical adjustment chute enables ±50mm vertical insertion and withdrawal adjustment. This effectively compensates for multidimensional deviations during equipment installation, significantly reducing the stringent requirements for installation accuracy and improving installation efficiency and adaptability to complex working conditions.

[0011] Enhanced system stability: Adjustable chutes effectively address thermal expansion and contraction caused by changes in material temperature and ambient temperature in the conveying system. Through its adjustable structure, it provides room for elongation during thermal expansion and appropriate contraction during cooling, thus preventing deformation and rupture caused by thermal stress and ensuring the stability and safety of the conveying system.

[0012] Ensuring airtightness: Even if there are some errors during installation, the adjustable chute can compensate through its own adjustment function, making the chute connection tighter, ensuring the airtightness and smoothness of the conveying system, reducing the possibility of material leakage, and avoiding material waste and environmental pollution caused by leakage.

[0013] Absorbing vibration energy: The adjustable components of the adjustable chute can absorb and buffer vibration energy to a certain extent, reduce the impact of vibration on the chute connection parts, reduce the risk of fatigue damage caused by vibration, extend the service life of the chute and related equipment, reduce the frequency of maintenance and replacement, and reduce maintenance costs.

[0019] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] like Figures 1-4 As shown, an adjustable chute for installation in conveying equipment includes an upper flange 2 connected to an upstream conveying device, a lower flange 3 connected to a downstream conveying device, and a chute body 1 connected between the upper flange 2 and the lower flange 3. The upper flange 2 and the lower flange 3 are rectangular frames, and the vertical cross-section of the side of the upper flange 2 is C-shaped to accommodate connecting bolts and gaskets. The vertical cross-section of the side of the lower flange 3 is L-shaped to form a groove for socketing and applying sealant. The chute body 1 also includes an adjustable connection structure 4. The top and bottom of the chute body 1 are respectively provided with an upper flat flange plate 11 and a lower flat flange plate 12. The upper flat flange plate 11 is bolted to the bottom of the upper flange 2. A flat washer and a spring washer are installed at the bolting point between the upper flat flange plate 11 and the upper flange 2 to enhance the tightness and anti-loosening ability of the connection.

[0022] The adjustable connection structure 4 includes a horizontal adjusting flange plate 41 and a vertical adjusting chute 42. The horizontal adjusting flange plate 41 is adjusted and fixedly connected to the bottom of the lower flat flange plate 12 in four directions (front, back, left, and right). The side width of the horizontal adjusting flange plate 41 is smaller than the side width of the lower flat flange plate 12, and its adjustment range in all directions is ±20mm. The horizontal adjusting flange plate 41 is welded and fixed to the lower flat flange plate 12. The top of the vertical adjusting chute 42 is fixedly connected to the horizontal adjusting flange plate 41, and its bottom is inserted into the lower flange 3. A ring of sealant is applied to the joint between the vertical adjusting chute 42 and the top of the lower flange 3. The top of the vertical adjusting chute 42 is butt-jointed with the inner ring side wall of the horizontal adjusting flange plate 41, and the joint is filled with sealant and spot-welded. The vertical adjustment range of the vertical adjusting chute 42 is ±50mm.

[0023] Specifically, the adjustable connection structure 4 is the core of the adjustment function of this utility model. The horizontal adjusting flange plate 41 is placed at the bottom of the lower flat flange plate 12. Because its side width is designed to be smaller than the side width of the lower flat flange plate 12, it can be moved and adjusted in four directions (front, back, left, and right) within the bottom surface of the lower flat flange plate 12, with an adjustment range of ±20mm. After the horizontal position is adjusted to be aligned with the lower flange 3, the horizontal adjusting flange plate 41 and the lower flat flange plate 12 are fixed firmly by welding. The top of the vertical adjusting chute 42 is connected to the inner ring side wall of the horizontal adjusting flange plate 41. In addition to structural contact, the connection is fixed and sealed by filling with sealant and spot welding. The bottom of the vertical adjusting chute 42 is inserted into the interior of the lower flange 3, and vertical adjustment is achieved by up and down insertion and withdrawal, with an adjustment range of ±50mm. After the vertical height is adjusted to the correct position, apply a ring of sealant to the annular joint between the bottom of the vertical adjusting chute 42 and the top of the lower flange 3 to form a reliable sealing layer. This effectively prevents dust and material leakage, improves the working environment, and reduces material loss.

[0024] The sealant is a highly elastic structural sealant, which has excellent adhesion, aging resistance and fatigue resistance. Its elasticity can maintain the integrity of the sealing interface, without cracking or falling off, even when the vertical adjusting chute 42 undergoes slight displacement due to thermal expansion and contraction or slight vibration, thus ensuring the long-term sealing performance of the conveying system.

[0025] During installation, initial positioning: connect the upper flat flange plate 11 to the upper flange 2 with bolts, but do not tighten them yet. Adjust the lower flange 3 according to its deviation using the characteristics of the adjustable chute.

[0026] Horizontal adjustment: Based on the deviation between the lower flange plate 12 and the lower flange 3 of the chute, move the horizontal adjustment flange plate 41 in four directions (forward, backward, left, and right) until it is aligned with the lower flange 3 (adjustment range ±20mm).

[0027] Vertical adjustment: Based on the deviation between the lower flange plate 12 and the lower flange 3 of the chute, adjust the vertical adjustment chute 42 up and down until it is aligned with the lower flange 3 (adjustment range ±50mm).

[0028] Locking and fixing: Apply the upper sealing gasket, tighten the bolts, and apply sealant to the entire circumference of the upper and lower adjustment area.

[0029] In operation, the material enters through the upper flange 2 inlet, flows through the chute body 1 and the adjustable connection structure 4, and finally exits through the lower flange 3 outlet. During installation, the entire adjustable chute compensates for deviations in the equipment interfaces through horizontal and vertical adjustments. During operation, it functions reliably as a structurally stable and well-sealed fixed channel. Its adjustable characteristics also facilitate subsequent equipment inspection and maintenance; if disassembly is required, the sealant can be removed and the spot welds ground open for separation.

[0030] After horizontal adjustment, the horizontal adjusting flange plate 41 and the lower flat flange plate 12 are fixed by welding. The vertical adjusting chute 42 and the horizontal adjusting flange plate 41 are fixed by a combination of spot welding and sealant. This ensures both adjustability and the mechanical strength and connection reliability of the overall structure, keeping the chute stable during material transport. The upper flange 2 and the upper flat flange plate 11 are bolted together, allowing for easy disassembly when necessary. The entire adjustable connection structure is rationally designed, avoiding the trouble of customizing non-standard parts or making large-scale on-site modifications due to errors in traditional methods, thus saving installation time and subsequent maintenance costs.
