Abstract
Description
Technical Field
[0001] This utility model relates to the field of unloading device technology, and in particular to a bulk material unloading device. Background Technology
[0002] In bulk material handling systems, belt conveyor unloading vehicles are key equipment, mainly used for unloading bulk materials.
[0003] The belt conveyor unloading car mainly consists of a transmission component and an unloading car. The transmission component is mainly used to transport bulk materials, while the unloading car is used to unload bulk materials at designated locations along the conveyor line. The transmission component includes rollers and a belt mounted on the rollers; the unloading car includes an unloader and the car body. Typically, the unloader is a plow-type unloader, which uses plow blades (mechanical scrapers) to push the bulk materials on the belt into a guide chute on one side of the belt, thus achieving directional unloading along the conveyor line. The unloading car body then transfers the bulk materials in the guide chute to the processing hopper.
[0004] However, in practical applications, it has been found that when the mechanical scraper pushes the material to the belt side guide chute, the dynamic friction between the mechanical scraper and the belt causes severe belt wear, which reduces the belt's service life. Furthermore, the mechanical scraper generates a large amount of dust during the process of pushing the material to the guide chute, which floats in the air and causes air pollution. Utility Model Content
[0005] The purpose of this invention is to provide a bulk material unloader to solve the problems mentioned in the background art.

[0044] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0045] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0046] Currently, when a mechanical scraper pushes material to the belt-side guide chute, the dynamic friction between the scraper and the belt causes severe belt wear, thus reducing the belt's service life. Furthermore, the mechanical scraper generates a large amount of dust during the process of pushing material to the guide chute, which floats in the air and causes air pollution.
[0047] like Figures 1-4 As shown, this embodiment of the utility model provides a bulk material unloader, which consists of a plurality of unloading units 1 along a belt conveyor path. Each unloading unit 1 includes:
[0048] The unloading body 11 has a multi-chamber structure, including multiple unloading chambers. The inlet end of each unloading chamber is connected through a flow channel, and the outlet end of each unloading chamber corresponds to a different receiving end.
[0049] The conveying assembly 12 extends along the conveying direction and penetrates the unloading body 11, corresponding to the unloading chamber.
[0050] When the unloader is in operation, the bulk material is conveyed to the unloading body 11 via the conveying assembly 12, and unloaded directionally from a portion of the multiple unloading chambers along the conveying line, and / or unloaded from another portion of the multiple unloading chambers along the conveying line to the next unloading unit 1.
[0051] Specifically, such as Figure 2 As shown, the conveying assembly 12 mainly includes: a plurality of support rollers 121 and a conveyor belt 122 disposed on the support rollers 121.
[0052] The conveyor belt 122 includes, in sequence along the conveying direction, several parts such as the first conveying section 1221, the turning section 1222, and the second conveying section 1223.
[0053] The first conveying section 1221 has one end connected to the feeding end and the other end passing through the unloading body 11; the first conveying section 1221 is configured to convey bulk material into the unloading body 11. One end of the turning section 1222 is located inside the unloading body 11 and connected to the first conveying section 1221, while the other end extends to the outside of the unloading body 11; the turning section 1222 changes the conveying direction, thereby allowing the bulk material to fall accurately into the unloading chamber. The second conveying section 1223 has one end connected to the turning section 1222 and the other end extending along the conveying direction until it connects to the conveying assembly 12 in the adjacent unloading unit 1. More specifically, the second conveying section 1223 is connected to the first conveying section 1221 in the adjacent unloading unit 1. The second conveying section 1223 is configured to convey bulk material into the adjacent unloading unit 1.
[0054] like Figures 2-3 As shown, the discharge chambers include several parts such as the first discharge chamber 111 and the second discharge chamber 112.
[0055] The first feed end 1111 of the first unloading chamber 111 corresponds to the first conveying section 1221, and the first discharge end 1112 of the first unloading chamber 111 corresponds to the second conveying section 1223. The bulk material conveyed on the first conveying section 1221 falls into the first unloading chamber 111 under the action of gravity, and then falls into the second conveying section 1223, from where it is conveyed to the adjacent unloading unit 1.
[0056] Furthermore, in order to control the flow rate of the bulk material in the first discharge chamber 111 and to switch between the open and closed states of the first discharge chamber 111, a first discharge valve 2 is provided at the first discharge end 1112 of the first discharge chamber 111. The opening degree of the first discharge end 1112 is precisely controlled by the first discharge valve 2, and the switching between the open and closed states of the first discharge chamber 111 is realized.
[0057] Furthermore, to prevent splashing and dust generation when bulk material falls from the first unloading chamber 111 into the second conveying section 1223, an extension chamber 3 is provided on the outer wall of the first unloading chamber 111. The bottom end of the extension chamber 3 extends towards the second conveying section 1223 until the second conveying section 1223 is completely enclosed within the extension chamber 3, forming a semi-sealed flow channel. That is to say, the second conveying section 1223 can slide through the bottom end of the extension chamber 3. The bulk material diverted from the first unloading chamber 111 is guided by the extension chamber 3 and falls into the second conveying section 1223, where it is then conveyed.
[0058] The second unloading chamber 112 is located below the first unloading chamber 111. The second feeding end 1121 of the second unloading chamber 112 is connected to the first feeding end 1111 of the first unloading chamber 111. The second discharge end 1122 of the second unloading chamber 112 corresponds to the processing hopper. The purpose of directional unloading along the conveyor line is achieved through the second unloading chamber 112.
[0059] Furthermore, in order to enable the second discharge end 1122 to match multiple processing bins, in this embodiment, the second discharge end 1122 includes several parts such as a first discharge section 11221, a second discharge section 11222, a guide section, and a drive section.
[0060] The first discharge section 11221 and the second discharge section 11222 are arranged side by side, and the first discharge section 11221 and the second discharge section 11222 correspond to the processing hopper, respectively. The drive unit is disposed on the outer wall of the first discharge section 11221 and the second discharge section 11222. The guide unit is rotatably disposed at the junction of the first discharge section 11221 and the second discharge section 11222, and is connected to the output end of the drive unit.
[0061] For example, in this embodiment, the driving part is a rotary cylinder 11224 and the guiding part is a guide plate 11223.
[0062] When it is necessary to adjust the dropping position of the bulk material, the rotary cylinder 11224 is activated. The rotary cylinder 11224 drives the guide plate 11223 to rotate. When the guide plate 11223 rotates towards the first discharge section 11221, the bulk material falls into the second discharge section 11222. When the guide plate 11223 rotates towards the second discharge section 11222, the bulk material falls into the first discharge section 11221. When the guide plate 11223 is infinitely close to the intersection of the first discharge section 11221 and the second discharge section 11222, the bulk material can fall into both the first discharge section 11221 and the second discharge section 11222 at the same time.
[0063] Furthermore, a second discharge valve 4 is provided at the bottom of the first discharge section 11221. The second discharge valve 4 controls the flow rate of the loose material passing through the first discharge section 11221 and enables the switching between the open and closed states of the first discharge section 11221.
[0064] Similarly, a third discharge valve 5 is provided at the bottom of the second discharge section 11222. The third discharge valve 5 controls the flow rate of the loose material passing through the second discharge section 11222 and enables the switching between the open and closed states of the second discharge section 11222.
[0065] Furthermore, in order to monitor the amount of bulk material stored in the first discharge section 11221 in real time, a first material level detector 6 is provided in the first discharge section 11221 in this embodiment.
[0066] Similarly, in order to monitor the amount of bulk material stored in the second discharge section 11222 in real time, a second material level detector 7 is provided in the second discharge section 11222 in this embodiment.
[0067] The working principles of the first level detector 6 and the second level detector 7 are both existing technologies, and will not be described in detail in this embodiment.
[0068] Furthermore, the bulk material unloader in this embodiment also includes a PLC controller (not shown in the figure). The PLC controller is used to realize the joint operation of the first material level detector 6, the second material level detector 7, and the first unloading valve 2. Its specific working principle is existing technology and will not be described in detail in this embodiment.
[0069] When using, such as Figures 2-3As indicated by the arrow, the bulk material is conveyed to the unloading body 11 via the first conveying section 1221. When the bulk material is conveyed to the end of the first conveying section 1221, it falls into the first unloading chamber 111 under the action of gravity. The bulk material is then transferred to the second conveying section 1223 via the first unloading chamber 111 and then conveyed to the adjacent unloading unit 1 by the second conveying section 1223. When bulk materials need to be transported to the processing silo, the first discharge valve 2 is closed. After the first discharge chamber 111 is full, the bulk materials overflow. With the cooperation of the guide plate 11223 and the rotary cylinder 11224, the bulk materials flow to the first discharge section 11221 and / or the second discharge section 11222, and then flow to the corresponding processing silo through the first discharge section 11221 and / or the second discharge section 11222 (the flow rate of bulk materials flowing out of the first discharge section 11221 and / or the second discharge section 11222 is less than the flow rate of bulk materials flowing into the first discharge section 11221 and / or the second discharge section 11222). (Flow rate of 22) When the first level detector 6 and / or the second level detector 7 detects that the amount of bulk material stored in the first discharge section 11221 and / or the second discharge section 11222 reaches the preset value, the first level detector 6 and / or the second level detector 7 feeds back the signal value to the PLC controller. The PLC controller controls the first unloading valve 2 to open, the first unloading chamber 111 is opened, and the bulk material is transported to the adjacent unloading unit 1 again, and processed again by the adjacent unloading unit 1 (unloaded by the adjacent unloading unit 1 to the downstream processing silo or continued to be transported to the next unloading unit 1).
[0070] Furthermore, in order to remove dust inside the unloading body 11, a dust removal air inlet 110 is provided on the unloading body 11. The dust in the unloading chamber inside the unloading body 11 is introduced into the dust removal system through the dust removal air inlet 110 and removed by the dust removal system.
[0071] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
