An impact-resistant transfer chute with water filtering function

Abstract

The present invention discloses an impact-proof transfer chute with a water filtering function, which includes an upper chute, a lower chute, a front-stage unloading part, and a water filtering device. This solution can reduce the impact of materials on the chute and filter out some of the moisture in the materials by adding an adjustable angle retaining groove at the upper part of the chute and a water filtering device at the lower part of the chute. In specific applications, the front-stage unloading part ejects the material onto the retaining groove at the upper part of the chute. The retaining groove can be appropriately adjusted according to the unloading trajectory, greatly reducing the impact of the material on the lower part of the chute. When the material slides down the retaining groove, it passes through the water filtering device embedded in the lower part of the chute. Most of the moisture in the material will be filtered out and discharged to a designated location, making the transfer point tidy, thereby making the entire conveying system more reliable, reducing equipment failure rate, and improving production efficiency.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0027] See also Figure 1, which shows a schematic diagram of the transfer chute structure in this solution. As can be seen from the figure, it mainly includes the upper chute portion 200, the lower chute portion 300, the pre-stage unloading section 100, and the water filter device 400. The upper chute portion 200 is connected to the pre-stage unloading section 100; the lower chute portion 300 is located below the upper chute portion 200; and the water filter device 400 is connected to the lower chute portion 300. This solution, by installing a movable retaining groove and a water filter device in the upper chute portion 200 and the lower chute portion 300, respectively, can filter out moisture from the material while reducing impact force.

[0028] For details, see Figure 2 The front-stage unloading section 100 is used to eject materials. It primarily consists of a front-stage unloading frame 110 and an unloading roller 120. The front-stage unloading frame 110 is triangular in shape, with the unloading roller 120 mounted above it. The top of the front-stage unloading frame 110 is equipped with protruding panels on both sides, each with connection holes 130 for connecting to the upper portion 200 of the chute.

[0029] The front-stage unloading rack 110 and the unloading roller 120 are well known to those skilled in the art and are not described in detail here.

[0030] See also Figure 3 The upper part 200 of the chute is mainly composed of a retaining groove 210, a telescopic rod assembly 220, a hanger 230, a connecting piece 240, and a slide 250.

[0031] Among them, see Figure 4 The retaining groove 210 is an arc-shaped groove that cushions the impact of ejected materials. The retaining groove 210 has an inner arc surface and an outer arc surface. The inner arc surface faces the unloading drum 120 and is used to receive the ejected materials. After being ejected, the materials slide down the inner arc surface to the lower portion 300 of the chute, thus providing a buffer against impact.

[0032] Two protruding panels 211 are symmetrically positioned along the outer arc of the retaining groove 210. Two sets of connecting lugs are symmetrically positioned between and below the two protruding panels 211: a first set of connecting lugs 212 and a second set of connecting lugs 213. The first set of connecting lugs 212 is used to connect to the carriage 250, while the second set of connecting lugs 213 is used to connect to one end of the telescopic rod assembly 220.

[0033] Since the retaining groove 210 is used to bear impact, the material used is preferably a high-strength material to ensure stability during use.

[0034] The telescopic rod assembly 220 is used to adjust the angle and distance between the retaining groove 210 and the unloading drum 110. The telescopic rod assembly 220 comprises a first telescopic rod and a second telescopic rod, which are used in conjunction with each other. One end of the first telescopic rod and the second telescopic rod are respectively connected to the second set of connecting ears 213 on the retaining groove 210, and the other end is connected to the upper hanger 230.

[0035] The first telescopic rod and the second telescopic rod are respectively provided with a plurality of pin holes, which are evenly distributed from top to bottom; the retaining groove 210 can be connected with the retaining groove 210 by selecting different pin holes on the telescopic rod to achieve the extension or shortening of the telescopic rod.

[0036] See also Figure 5 The hanger 230 is located above the entire device and is in a U-shaped shape. The ports on both sides of the open end of the hanger 230 have a small downward design, which is set downward at about 135 degrees relative to the plane where the crossbeam is located.

[0037] The top of the lower sliding end 234 is provided with a connecting hole 235, which is used to be pin-connected to the connecting holes 130 on both sides of the top of the front-stage unloading frame. The hanger 230 can swing around the connecting hole at a certain angle. When ejecting materials, a certain angle can be adjusted according to the ejection arc of the material.

[0038] Two lifting ears 231 are positioned opposite each other on the inner side of the front beam of the hanger 230. The outer walls of the lifting ears 231 have pin holes for threaded connection with the screw holes on the vertical surfaces of two L-shaped connectors 240, thereby connecting the connectors 240 to the lifting ears 231, and thus connecting the hanger 230 to the connectors 240. Multiple sets of equidistant holes 233 are positioned on the upper sides of the beams of the hanger 230, which connect to the carriage 250.

[0039] A slide 250 is provided in the middle of the hanger 230 for changing the distance between the retaining groove 210 and the unloading drum 120. Figure 6 , connecting holes 251 for connecting to the hanger are provided on both sides of the slide 250; the connecting holes 251 on both sides of the slide 250 match the connecting holes 233 on the beams on both sides of the hanger 230, and different connecting holes can be selected for connection, so that the slide 250 can move back and forth on the hanger 230 to change the distance between the retaining groove 210 and the unloading drum 120.

[0040] Two lifting ears 252 are provided under the crossbeam of the slide 250 and are provided with pin holes, which are connected to the first group of connecting ear seats 212 provided on the arc surface of the retaining groove.

[0041] The two connectors 240 are L-shaped and have several sets of pin holes evenly distributed from top to bottom. The lugs 231 on the front beam of the hanger 230 can be connected to different pin holes of the connectors 240, allowing the hanger 230 to swing around the connection hole 130 at a certain angle through the connection holes 235.

[0042] The upper part 200 of the chute is formed by the interconnection of the telescopic rod assembly 220, the connecting piece 240, the slide 250, the retaining groove 210 and the hanger 230. In specific applications, the slide 250 moves back and forth on the hanger 230 by connecting different holes. When moving back and forth, the retaining groove 210 can be moved closer to or away from the unloading roller 120 by coordinating the extension and contraction of the telescopic rod assembly 220; if the slide 250 is stationary, the retaining groove 210 can be swung up and down by a certain angle by adjusting the extension and contraction of the telescopic rod assembly 220 and the position of the hanger 230 and the connecting piece 240.

[0043] The angle of material ejection is adjusted through the above-mentioned action so that after the material is ejected from the unloading drum 120, it is first ejected to the inner arc surface of the retaining groove 210 and then slides to the lower part 300 of the chute, thereby achieving the purpose of impact prevention.

[0044] See also Figure 7 The lower part 300 of the chute is mainly composed of a chute body 310, a primary water filter plate 320 and a chute body connecting support structure 330.

[0045] The trough body 310 is used to receive the material sliding down from the upper part 200 of the chute. The trough body 310 is a U-shaped trough body with a curve, which is conducive to the shaping and sliding of the material. The trough body 310 is provided with an opening in the middle for installing the first-level water filter plate 320.

[0046] The primary water filter plate 320 is used to filter water from the material and is connected to the tank body 310 by bolts. The size of the water filter plate should match the opening on the tank body 310 and can just cover the opening.

[0047] The composition and structure of the primary water filter plate 320 are well known to those skilled in the art and will not be described in detail here.

[0048] The tank body connection support structure 330 located at both ends of the tank body 310 is used to support the tank body 310 and is welded to the tank body 310. It is composed of 4 support legs and 2 crossbeams.

[0049] The four support legs are symmetrically located on both sides and the rear end of the tank body 310. Each leg has bolt holes for connecting to the crossbeam. Two crossbeams are located at the bottom of the support legs on both sides and the rear end of the tank body 310, and are threadedly connected to the four support legs.

[0050] There is no limitation on the configuration of the tank body connection support structure 330 and it can be determined according to the actual situation.

[0051] The lower part 300 of the chute is composed of a chute body 310, a primary water filter plate 320, and a chute body connecting support structure 330. In specific applications, the material sliding down from the upper part 200 of the chute slides into the chute body 310. During the process of sliding down in the chute body 310 to the lower loading point, the material passes through the primary water filter plate 320 in the chute body. During this process, the moisture in the material is filtered in the primary stage. The filtered water enters the water filter device 400 for secondary filtration.

[0052] The water filter device 400 is used to further filter the material. It is located at the bottom of the tank 310 and is placed opposite to the first-level water filter plate 320. Figure 8 , which is mainly composed of a secondary water filter plate 410 and a water storage tank 420.

[0053] The secondary water filter plate 410 is detachable and connected to the water storage tank 420 by bolts. The size of the secondary water filter plate 410 also matches the size of the first water filter plate 320, so that the water filtered by the first water filter plate 320 can flow into the secondary water filter plate 410.

[0054] The water tank 420 stores filtered water. Its port dimensions match those of the secondary water filter plate 410, allowing it to be embedded within the port. Two symmetrical screw holes are located at its upper end, securing it to the lower tank body 310 via bolts. Two symmetrical pin holes are located on either side of the lower end, securing it to the lower tank body 310 via pins. To clean or replace the secondary water filter plate 410, loosen the upper bolts and rotate it through the pin holes to open the filter unit 400 and remove it.

[0055] In addition, a water outlet 430 is provided at the rear end of the water storage tank 420. The water pipe of the water outlet 430 is arranged horizontally or downwardly inclined to facilitate the timely removal of water from the water storage tank. The water outlet 430 directs the coal water to a designated location via a flanged hose, thereby tidying up the transfer site, reducing equipment failure rates, making the entire conveying system more reliable, and improving production efficiency.

[0056] During operation, the water pipe is first connected to the water outlet 430 via a flange. If the material contains a lot of water, the water is filtered through the primary filter plate 320 and the secondary filter plate 410 as the material descends, and then discharged through the water tank outlet 430 to the designated location. This method removes most of the water from the material, leaving the downstream loading point clean and tidy, and reducing equipment failures at the transfer point.

[0057] The following example illustrates the working process of this solution in a specific application.

[0058] First, the upper part of the chute is connected to the front-stage unloading frame 110 through the hanger 230, and the connecting piece 240 is connected to the top plate during operation. The sliding frame 250 cooperates with the telescopic rod assembly 220, and the position and angle of the retaining groove can be adjusted by changing the pin hole connected.

[0059] During operation, after the material is ejected through the unloading roller 120, the position and angle of the upper retaining groove 210 of the chute and the unloading roller 120 are appropriately adjusted through the telescopic rod assembly 220 and the connecting piece 240 according to the ejection trajectory, so that the material can first be accurately ejected onto the inner arc surface of the retaining groove 210, and then slide along the inner arc surface into the U-shaped trough body 310 at the bottom of the chute. The U-shaped trough body 310 can make the material properly shaped and then slide to the next loading point, avoiding a series of problems caused by the material being directly ejected to the next loading point, such as direct impact on the loading point causing wear of the belt, deviation of the lower belt and material spillage, etc.

[0060] In addition, when the material passes through the lower U-shaped trough 310 of the chute, a water filter 400 is set inside. If the water content of the transported material is large, most of the water will be filtered out by the water filter during the sliding process of the material, making the lower loading point tidy.

[0061] The impact-proof transfer chute with water filtering function constructed according to the above scheme has a retaining groove set in the upper part of the chute, which can be appropriately adjusted according to the unloading trajectory, thereby greatly reducing the impact of the material on the chute; secondly, a water filtering device is set at the lower part of the chute to filter out most of the water in the material, making the operation of the entire conveying system more reliable, reducing the equipment failure rate, and improving production efficiency.
