Description

Technical Field

[0001] The utility model relates to the technical field of mobile discharging of mine belt conveyors, in particular to an environment-friendly mobile discharging vehicle. Background Technique

[0002] Bin storage is a common way to store solid bulk materials in industrial and mining enterprises. In recent years, with the strong promotion of environmental protection ultra-low emission transformation in various industries, the transformation of material warehousing has been further accelerated. Single-row or double-row bins are often set up in the material storage workshop, and multiple continuously arranged bins are set in each row. After the materials are transported to the top of the bins by a belt conveyor, they are transported to the bins that need to be fed by a supporting mobile discharging vehicle, and the materials are discharged into the bins. The travel length of the mobile discharging vehicle is basically the same as the total length of the single-row bins.

[0003] During the discharging operation, a large amount of unorganized emission dust will be generated at the head hopper, the discharge chute outlet of the mobile discharging vehicle, and the feeding hole of the bin. Therefore, a mobile ventilation duct is usually configured to prevent the pollution caused by the unorganized emission of dust during the discharging operation of the mobile discharging vehicle. The mobile ventilation duct is a sealed housing structure, that is, a closed rectangular parallelepiped pipe. A long through hole is opened on its upper surface, and a sealing rubber sheet is configured to seal the hole. At the same time, a hole is opened at one end of the rectangular parallelepiped pipe to connect with the workshop dust removal pipe network. In this way, the mobile ventilation duct becomes a supporting dust removal pipe for the mobile discharging vehicle. A mobile dust removal trolley is arranged on the upper surface of the mobile ventilation duct. There is a ventilation port at the bottom of the mobile dust removal trolley to cooperate with the hole on the upper surface of the mobile ventilation duct. At the same time, there is also a ventilation port on the side of the mobile dust removal trolley, which is connected to the dust removal hood of the head hopper of the mobile discharging vehicle through a dust removal pipe to capture the dust at the head hopper. At the same time, a branch pipe of the dust removal pipe is arranged beside the discharge port of the discharge chute of the mobile discharging vehicle to form the capture of the dust at the discharge port of the discharge chute. A long cover bin sealing tape (basically the same as the total length of the single-row bins) is arranged at the feeding hole of the bin to cooperate with the mobile discharging vehicle to form the sealing of the feeding hole of the bin and prevent the dust in the bin from escaping.

[0004] Disadvantages of the above-mentioned movable ventilation duct: 1) The length of the movable ventilation duct is basically the same as the stroke length of the movable discharging vehicle. Therefore, the length of the movable ventilation duct is generally dozens of meters or even more than one hundred meters. Thus, the movable ventilation duct is generally composed of multiple short joints with shorter lengths through splicing and assembly. The more the number of splicing joints, the more air leakage points there are. At the same time, the flatness in the length direction is worse. As a result, the sealing performance of the movable ventilation duct is damaged, affecting the dust removal effect; 2) The length of the movable ventilation duct is relatively long, which easily causes deflection deformation in the length direction, affecting the flatness of the upper surface of the movable ventilation duct, and further affecting the smoothness of the movement of the movable dust removal trolley, resulting in a dragging phenomenon due to the asynchronous movement of the movable dust removal trolley and the movable discharging vehicle. This not only poses potential safety hazards in production but also causes deformation of the movable ventilation duct and damage to its sealing performance, affecting the dust removal effect; 3) The sealing rubber on the upper part of the movable ventilation duct is prone to aging and deformation. At the same time, it is also extremely easy to deviate, resulting in damage to the sealing performance of the movable ventilation duct and affecting the dust removal effect; 4) For the dust removal pipeline from the movable dust removal trolley to the discharging chute, a relatively large number of elbows often need to be set to connect to the discharge port of the discharging chute. The large number of elbows increases the resistance of the dust removal pipeline, affecting the dust removal effect; 5) The side ventilation opening of the movable dust removal trolley of the movable ventilation duct is connected to the dust removal hood of the head hopper of the movable discharging vehicle through a horizontal dust removal pipeline. The dust removal hood of the head hopper of the movable discharging vehicle is generally at least five meters above the ground. Therefore, the installation height of the movable ventilation duct is also at least five meters above the ground. Since the internal accumulated ash of the movable ventilation duct needs to be cleaned after being in use for a period of time, the installation height of the movable ventilation duct makes the ash cleaning operation a high-altitude operation, which not only has a relatively large operation difficulty but also poses potential safety hazards in production.

[0005] Currently, according to the structural characteristics of the movable discharging vehicle, a movable dust collector has emerged, which can replace the original movable ventilation duct to effectively capture the unorganized emission of dust during the discharging operation of the movable discharging vehicle. While solving the above-mentioned disadvantages of the movable ventilation duct, it improves the dust removal effect. The existing movable dust collectors mainly have two forms: vehicle-mounted movable dust collectors and following movable dust collectors.

[0006] The vehicle-mounted movable dust collector, that is, by setting 1 vehicle-mounted movable dust collector on the head or tail frame of the movable discharging vehicle to capture the dust at the discharge port of the discharging chute of the movable discharging vehicle. The reverse blowing and ash cleaning of the vehicle-mounted movable dust collector fall onto the conveyor belt surface of the belt conveyor belonging to the movable discharging vehicle. A sealed material guiding chute and a dust removal hood are configured at the ash receiving point on the conveyor belt surface to capture the dust at the ash receiving point. The vehicle-mounted movable dust collector is provided with a dust removal pipeline connected to the side of the discharge port of the discharging chute of the movable discharging vehicle and the dust removal hood of the material guiding chute at the ash receiving point, so as to effectively capture the dust at the discharge port of the discharging chute and the receiving point.

[0007] Disadvantages of the above-mentioned on-vehicle mobile dust collector: 1) All loads of the on-vehicle mobile dust collector are borne by the mobile unloading truck. Therefore, the strength requirement of the mobile unloading truck frame is higher than the standard configuration. At the same time, the driving motor power is also increased by 1 to 2 gears compared with the standard configuration. For retrofit projects, it is necessary to reinforce the frame structure of the mobile unloading truck and replace the driving motor, resulting in increased costs such as investment, construction, and construction period; 2) Although the number of elbows in the dust removal pipeline leading to the unloading chute of the on-vehicle mobile dust collector has been reduced compared with the mobile ventilation chute, there are still a certain number of elbows. The problem of the elbows increasing the resistance of the dust removal pipeline and affecting the dust removal effect is only weakened but not eradicated, and the dust removal effect for easily dust-generating materials such as coke and sinter is still not ideal; 3) The reverse blowing and dust cleaning of the on-vehicle mobile dust collector fall onto the conveyor belt surface of the belt conveyor belonging to the mobile unloading truck. Although the dust receiving point on the conveyor belt surface is equipped with a sealed material guiding chute and a dust removal hood to capture the dust at the dust receiving point, the sealing parts of the sealed material guiding chute are vulnerable parts, and there is still dust leakage when they are damaged. The above disadvantages have led to the on-vehicle mobile dust collector not being widely used in the ultra-low emission retrofit of the iron and steel industry.

[0008] The follow-up mobile dust collector, that is, by setting one follow-up mobile dust collector on each side of the unloading chute of the mobile unloading truck to capture the dust at the discharge port of the unloading chute of the mobile unloading truck, and the reverse blowing and dust cleaning of the follow-up mobile dust collector fall into the silo. The air inlet of the follow-up mobile dust collector and the discharge port of the unloading chute are made into an integral sealing hood to effectively capture the dust at the discharge port of the unloading chute.

[0009] Disadvantages of the above-mentioned follow-up mobile dust collector: 1) All loads of the follow-up mobile dust collector are borne by the mobile unloading truck. Therefore, the strength requirement of the mobile unloading truck frame is higher than the standard configuration. At the same time, the driving motor power is also increased by 1 to 2 gears compared with the standard configuration. For retrofit projects, it is necessary to reinforce the frame structure of the mobile unloading truck and replace the driving motor, resulting in increased costs such as investment, construction, and construction period; 2) The follow-up mobile dust collector can only effectively capture the dust at the discharge port of the unloading chute, and there is no capture of the dust at the head hopper of the mobile unloading truck, resulting in dust leakage at this place; 3) The follow-up mobile dust collector is located on both sides of the unloading chute, and its air inlet and the discharge port of the unloading chute are made into an integral sealing hood. During the unloading operation of the mobile unloading truck, a large amount of scattered materials are accumulated around the feeding hole of the silo due to the splashing of materials. When the height of the scattered material accumulation is higher than the space between the follow-up mobile dust collector and the silo platform, the follow-up mobile dust collector is blocked and lifted by the scattered materials, which in turn affects the walking of the entire mobile unloading truck and is extremely prone to safety production accidents. In order to prevent this working condition from occurring, on-site operators often need to clean the accumulated scattered materials from time to time, increasing the labor intensity of the on-site workers and being prone to safety production accidents where workers are injured by moving equipment. The above disadvantages have led to the follow-up mobile dust collector not being widely used in the ultra-low emission retrofit of the iron and steel industry.

[0010] It can be seen that how to innovate and improve the dust removal method in the production operation process of the existing mobile unloading truck is an urgent problem to be solved at present. Summary of the Invention

[0011] The purpose of the present utility model is to provide an environment-friendly mobile unloading truck to solve the problems existing in the above-mentioned related technologies, which can effectively control the unorganized emission of dust during the mobile unloading operation of the belt conveyor for solid bulk materials in industrial and mining enterprises. On the basis of ensuring good dust removal effect, it is more adaptable to the actual working conditions of the renovation project, and effectively helps industrial and mining enterprises to greatly save costs in equipment, installation, construction period and maintenance inspection in the ultra-low emission renovation project.

Detailed Embodiments

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] The purpose of the present utility model is to provide an environment-friendly mobile discharging vehicle to solve the problems existing in the related technologies, which can effectively control the unorganized emission of dust during the mobile discharging operation of the belt conveyor for solid bulk materials in industrial and mining enterprises. On the basis of ensuring good dust removal effect, it is more adaptable to the actual working conditions of the renovation project, and effectively helps industrial and mining enterprises to greatly save costs in equipment, installation, construction period and maintenance in the ultra-low emission renovation project.

[0031] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] As Figure 1 shown, this embodiment provides an environment-friendly mobile discharging vehicle, which includes a discharging vehicle body 1. A discharging vehicle head funnel 2 is arranged at the head of the discharging vehicle body 1. The discharge port of the discharging vehicle head funnel 2 is connected with a discharging chute 3. The discharging vehicle body 1 can move along the mobile discharging vehicle track 01 of the belt conveyor, so that the materials conveyed by the belt conveyor are sequentially discharged into the silo through the discharging vehicle head funnel 2 and the discharging chute 3. It also includes a single-point dust collector 4 and a mobile dust removal device. The single-point dust collector 4 is arranged on the discharging vehicle head funnel 2 and is used to remove the dust generated when the materials fall in the discharging vehicle head funnel 2. The mobile dust removal device includes a dust collector walking track 5, a mobile sealing trolley 6 and a mobile dust collector 7. The dust collector walking track 5 extends along the direction of the mobile discharging vehicle track 01 of the belt conveyor, and there are two dust collector walking tracks 5, which are respectively located on both sides of the feeding hole 02 of the silo. The mobile sealing trolley 6 is arranged on the dust collector walking track 5 and is located below the discharging chute 3. The mobile dust collector 7 is arranged on the mobile sealing trolley 6 and is connected with the discharging chute 3, so that the discharging chute 3 can drive the mobile sealing trolley 6 to move along the dust collector walking track 5. When the mobile sealing trolley 6 moves above the feeding hole 02 of the silo, a sealed space is formed between the mobile sealing trolley 6, the dust collector walking track 5 and the feeding hole 02 of the silo, and the air inlet of the mobile dust collector 7 and the discharge port of the discharging chute 3 are both communicated with the sealed space, so that the mobile dust collector 7 removes the dust generated when the discharging chute 3 discharges materials.

[0033] It should be noted that Figure 1Shown is the case of double-sided discharging (i.e., setting double-sided chutes) of the environment-friendly mobile discharging truck provided in this embodiment. Each discharging chute 3 is equipped with a set of mobile dust removal devices.

[0034] It should be noted that the discharging truck body 1 is a standard device, which is consistent with the equipment parameters in the "Belt Conveyor Design Manual". By moving on the mobile discharging truck track 01 of the belt conveyor, the materials conveyed by the belt conveyor are discharged into the specified production silo.

[0035] It should be noted that the discharging truck head hopper 2 is a standard accessory of the discharging truck body 1, which is consistent with all the parameters in the "Belt Conveyor Design Manual" and is used to transfer the materials conveyed by the belt conveyor to the discharging chute 3.

[0036] It should be noted that the discharging chute 3 is a standard accessory of the discharging truck body 1, which is consistent with all the parameters in the "Belt Conveyor Design Manual" and is used to discharge the materials transferred by the discharging truck head hopper 2 into the silo through the feed opening 02 of the silo.

[0037] In this embodiment, the single-point dust collector 4 is vertically arranged on the top of the discharging truck head hopper 2, and the bottom of the single-point dust collector 4 is flange-connected to the top of the discharging truck head hopper 2; the air inlet of the single-point dust collector 4 is arranged downward and communicated with the discharging truck head hopper 2; by setting the single-point dust collector 4 to capture the dust generated during the material falling of the discharging truck head hopper 2, the main functions similar to the existing mobile ventilation trough are realized. However, relatively speaking, the single-point dust collector 4 has higher efficiency and better dust removal effect, effectively preventing the dust in the discharging truck head hopper 2 from escaping and causing environmental pollution in production.

[0038] Specifically, the single-point dust collector 4 in this embodiment is preferably a cartridge dust collector with a dust removal air volume of about 3000m 3 / h - 4000m 3 / h. The single-point dust collector 4 adopts a high-efficiency cartridge dust collector, which has the advantages of large filtering area, low filtering wind speed, small equipment shape and light equipment weight. It can not only meet the space size provided by the discharging truck head hopper 2, but also capture the dust generated during the discharging process in a timely and efficient manner, avoiding the dust removal failure caused by the blockage and increased resistance loss of the dust removal pipeline, and effectively preventing the dust in the discharging truck head hopper 2 from escaping and causing environmental pollution in production.

[0039] In this embodiment, the mobile dust collector 7 is vertically arranged on one side of the discharging chute 3, and the middle part of the mobile dust collector 7 is key-pinned to the discharging chute 3, and the bottom of the mobile dust collector 7 is flange-connected to the mobile sealing trolley 6; the air inlet of the mobile dust collector 7 and the discharge port of the discharging chute 3 are both arranged downward and communicated with the sealing space formed below the mobile sealing trolley 6.

[0040] In this embodiment, the mobile sealing trolley 6 includes a vehicle cover plate, a walking wheel assembly, and an enclosure assembly. The vehicle cover plate can move along the dust collector walking track 5 through the walking wheel assembly, and the bottom of the mobile dust collector 7 is flange-connected to the top of the vehicle cover plate. That is, by arranging the walking wheel assembly at the bottom of the vehicle cover plate, the mobile dust collector 7 is carried to move cooperatively with the unloading vehicle body 1 on the dust collector walking track 5; an air outlet and a feed inlet are arranged on the vehicle cover plate. The air inlet of the mobile dust collector 7 is connected to the air outlet of the vehicle cover plate, and the discharge outlet of the discharge chute 3 is connected to the feed inlet of the vehicle cover plate; the enclosure assembly is arranged at the bottom edge of the vehicle cover plate to form a sealed space between the vehicle cover plate, the dust collector walking track 5, and the feed inlet opening 02 of the silo.

[0041] Further, two mobile dust collectors 7 are provided. The two mobile dust collectors 7 are respectively located at the front side and the rear side of the discharge chute 3; two air outlets are arranged on the vehicle cover plate, and the two air outlets are respectively located at the front side and the rear side of the feed inlet on the vehicle cover plate. The air inlets of the two mobile dust collectors 7 are respectively connected to the two air outlets.

[0042] It should be noted that in this embodiment, an enclosure assembly is arranged at the bottom of the vehicle cover plate. A closed space is formed among the vehicle cover plate, the enclosure assembly, and the dust collector walking track 5 to integrally enclose the area between the air inlets of the two mobile dust collectors 7, the discharge outlet of the discharge chute 3, and the corresponding feed inlet opening 02 of the silo (i.e., the discharge area of the discharge chute 3), ensuring that the mobile dust collector 7 can timely and efficiently capture the dust generated during the discharging of the discharge chute 3.

[0043] It should be noted that in this embodiment, the two mobile dust collectors 7 are both connected and fixed to the mobile sealing trolley 6 through bottom flanges to form an integral body, and their overall load is borne by the dust collector walking track 5. At the same time, the middle shell of the mobile dust collector 7 is connected and fixed to the discharge chute 3 by means of key pins. When the unloading vehicle body 1 moves, by providing a very small load force through the discharge chute 3, the two mobile dust collectors 7 and the mobile sealing trolley 6 can be dragged to move on the dust collector walking track 5, and the impact on the overall strength of the unloading vehicle body 1 and the motor power can be completely ignored. For renovation projects, neither the unloading vehicle body 1 needs to be integrally reinforced nor a motor with a larger power needs to be replaced, greatly saving the equipment, installation, construction period, and maintenance costs of industrial and mining enterprises in the ultra-low emission renovation project, and is particularly suitable for application in the ultra-low emission renovation of the steel industry.

[0044] Specifically, the mobile dust collector 7 in this embodiment is preferably a cartridge dust collector with a dust removal air volume of about 5000m 3 / h - 6000m 3 / h. The air inlets of the two mobile dust collectors 7 are arranged close to the discharge outlet of the discharge chute 3 to ensure that there is an air volume of about 10000m 3 / h - 12000 m 3 The dust removal air volume of / h is sufficient to timely and efficiently capture the dust generated during the unloading process. At the same time, the reverse blowing and dust cleaning of the mobile dust collector 7 (the cartridge dust collector has a built-in reverse blowing and dust cleaning function) can directly enter the silo, eliminating the ash unloading and ash conveying links, simplifying the process flow, and reducing the failure probability.

[0045] In this embodiment, a wear-resistant guiding plate 8 is provided between any dust collector walking track 5 and the feeding hole 02 of the silo. The wear-resistant guiding plate 8 is a strip-shaped plate, and the length direction of the wear-resistant guiding plate 8 is arranged along the direction of the dust collector walking track 5. The width direction of the wear-resistant guiding plate 8 is inclined downward from the dust collector walking track 5 towards the feeding hole 02 of the silo. Specifically, the angle between the wear-resistant guiding plate 8 and the ground is preferably 45° - 60°.

[0046] In this embodiment, any dust collector walking track 5 includes a track body and a track fixing base. The track body is fixed to one side of the feeding hole 02 of the silo through the track fixing base. Specifically, the specification of the track body in this embodiment is preferably 9 kg / m; the upper side of the wear-resistant guiding plate 8 is fixedly connected to the corresponding track fixing base, and the lower side of the wear-resistant guiding plate 8 is supported at a position close to the feeding hole 02 of the silo.

[0047] It should be noted that for the installation of the dust collector walking track 5, in accordance with the requirements of the "General Code for Construction and Acceptance of Mechanical Equipment Installation Engineering", the track body and the track fixing base are installed and fixed on both sides of the feeding hole 02 of the silo in the length direction. Its length is basically the same as the length of the moving unloading truck track 01 of the belt conveyor (i.e., the walking track of the unloading truck body 1), and the installation position only needs to avoid interfering with the walking track of the unloading chute 3. The dust collector walking track 5 bears all the loads of the two mobile dust collectors 7 and the mobile sealing trolley 6.

[0048] It should be noted that for the installation of the wear-resistant material guide plate 8, it is installed between the dust collector walking track 5 and the feeding hole 02 of the silo. Its length is consistent with that of the dust collector walking track 5. The upper end of the wear-resistant material guide plate 8 is welded and fixed on the track fixing base platform. The lower end of the wear-resistant material guide plate 8 is supported on the ground beside the feeding hole 02 of the silo by its own weight and forms an installation inclination angle of about 45°-60° with the ground, ensuring that all materials falling out of the self-unloading chute 3 can fall into the silo, preventing the materials from scattering and splashing, resulting in a large amount of scattered materials accumulating around the feeding hole 02 of the silo. At the same time, the inclined installation of the wear-resistant material guide plate 8 can effectively prevent the cover bin sealing tape arranged at the feeding hole 02 of the silo from running off, that is, the wear-resistant material guide plate 8 can cooperate with the cover bin sealing tape configured at the feeding hole 02 of the silo, so as to form a good seal to prevent the dust in the silo from escaping; for the material of the wear-resistant material guide plate 8, since the wear-resistant material guide plate 8 is in direct contact with the materials falling out of the unloading chute 3, the wear-resistant material guide plate 8 needs to be made of wear-resistant material.

[0049] In summary, through the combined action of each component, the integrity of the structural function of the environmental protection type mobile unloading vehicle provided by the present utility model is constituted, ensuring that all the dust generated at all unloading points can be captured in a timely and efficient manner during the unloading operation; the overall structure of the environmental protection type mobile unloading vehicle provided by the present utility model is simple and reliable, the unloading and dust removal process flow is short, the assembly of each component is convenient and durable. Among all the components, only the single-point dust collector 4 and the mobile dust collector 7 need production inspection and replacement of spare parts, and the other components are durable parts and basically do not require maintenance. The single-point dust collector 4 is fixed on the hopper 2 at the head of the unloading vehicle, and here the unloading vehicle body 1 is provided with a maintenance platform according to the standard requirements of the "Belt Conveyor Design Manual", which is convenient for maintenance workers to operate. The mobile dust collector 7 is fixed on the mobile sealing trolley 6, and the maintenance personnel can operate while standing on the ground. Therefore, compared with the high-altitude maintenance operation of the existing mobile ventilation trough, the inspection and maintenance of the entire equipment of the present utility model are safer and more convenient.

[0050] In the present utility model, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
