Description

Technical Field

[0001] The utility model relates to a dragging type environmentally friendly quantitative coke loading equipment, which is a loading machine and a loading system which uses mechanical automation to load coke. Background Art

[0002] Automated vehicle loading stations can accurately weigh bulk materials such as coal and grain and quickly load them into trucks. They are efficient and commercially compliant automated loading machines. Coke is a material that is easily broken into powder and has poor fluidity. It is easy to generate dust during loading and unloading, and the loading and unloading efficiency is low. In the process of automatic loading using traditional automatic stations, since traditional loading stations usually have multiple flow channel links such as buffer bins, weighing bins, and chutes, it is easy for blockages and other retention phenomena to occur at the junction of each link. Since coke is easy to break, the dust generated by the powder formed during the loading process spreads and affects the environment. How to reduce blockages during the automatic loading process of coke and reduce the impact of dust on the surrounding environment is a problem that needs to be solved. Summary of the invention

[0003] In order to overcome the problems of the prior art, the utility model proposes a dragging type environmentally friendly quantitative loading equipment for coke. The system reduces the falling height of coke and uses floor weighing to overcome the fragility and poor fluidity of coke. It also adopts the method of dragging a vehicle to load the coke, as well as enclosure and dust collection facilities, so as to keep the coke loading fast and clean and reduce the breakage of coke.

[0020] Embodiment 1:

[0021] This embodiment is a drag-type coke environmental protection quantitative loading equipment, as Figure 1 shown. This embodiment includes: a steel structure frame 1, on which a head 2 of a belt conveyor, a bin 3, a cut-off and discharge arc gate 4, a telescopic chute 5, and a swing anti-breakage gate 6 are sequentially arranged from top to bottom. A cut-off gate 7 is provided at the end of the gate plate of the swing anti-breakage gate. A closed dust-proof cover 8 with a dust removal device is provided at the lower part of the steel structure frame. Automatic inlet doors 801 and automatic outlet doors 801 are provided at both ends of the closed dust-proof cover. A vehicle dragging device 9 and a weighbridge 10 are sequentially arranged on the ground inside the closed dust-proof cover from top to bottom. The weighbridge is electrically connected to a controller, and the controller is electrically connected to the dust removal device, the belt conveyor, the level gauge in the bin, the cut-off and discharge arc gate, the telescopic chute, the swing anti-breakage gate, the cut-off gate, and the vehicle dragging device, as Figure 2 shown.

[0022] In view of the characteristics of coke being fragile and having poor fluidity, this embodiment takes measures to minimize the dropping height of coke and reduce the dropping links. Specifically, the weighing bin in the traditional loading station is abandoned, which reduces the dropping links of coke and also lowers the height of the steel structure frame. Since the steel structure frame is the overall support and must be stable and reliable to ensure safe production, it accounts for a relatively large share in the total cost of the loading station. The reduction of the height of the steel structure frame brings an obvious decrease in cost.

[0023] The belt conveyor described in this embodiment conveys the piled coke on the ground or close to the ground to the top of the steel structure frame and into the silo. The belt conveyor can adopt frequency conversion to regulate the conveying speed to ensure that the coke contained in the silo is in a state where it can be stably loaded into the vehicle. A level sensor can be set in the silo to control the conveying speed of the belt conveyor according to the height of the material level, usually maintaining a loading capacity in the silo that can load 1-2 vehicles.

[0024] The silo can be cylindrical at the upper part and conical at the bottom, so that the coke can naturally fall by gravity to form an automatic material flow. An arc-shaped gate for discharging and cutting off the material is provided below the silo. Due to the poor fluidity of the coke, the surface of the particles is very rough, and there is a large frictional force between the particles. Not only is the fluidity poor, but the resistance to various mobile devices is also very large. Therefore, in this embodiment, an arc-shaped gate is provided at the discharge port of the silo. When the coke flows out of the silo under the action of gravity, the moving direction is vertically downward. The moving track of the gate plate of the arc-shaped gate is circular arc-shaped, and when it is opened, it moves obliquely upward, as Figure 3 indicated by the arrow B in the figure. The frictional force between the gate plate and the coke is relatively small, and the opening force is relatively small compared with that of a flat gate.

[0025] The telescopic chute described is a straight-up-and-down telescopic chute. This chute has a simple structure and can be controlled up and down by a hydraulic cylinder. When unloading starts, the chute extends to get as close as possible to the bottom of the carriage, so that the coke falls into the carriage at the shortest distance, avoiding the crushing of coke particles. When the coke accumulates on the carriage floor, the telescopic chute rises as the height of the material pile increases, enabling the coke to accumulate smoothly.

[0026] At the bottom of the telescopic chute, this embodiment is provided with a swinging anti-breaking gate with an inclined chute. When this gate is closed, it seals the entire bottom of the chute, preventing the coke from flowing out of the chute. When the gate is opened, the gate plate swings obliquely downward to form a slope, enabling the coke to flow down the slope into the carriage, thus avoiding the crushing of coke particles. The cross-sectional shape of the swinging anti-breaking gate can be designed as a dustpan shape for storing a small amount of coke. Because when the loading is about to reach the loading capacity, although the arc-shaped gate for discharging and cutting off the material reduces the opening degree or is completely closed, there is still some coke left in the chute. When the weighing sensor notifies that the coke in the carriage has reached the loading capacity, the cut-off gate immediately closes, and the remaining coke in the chute falls into the dustpan-shaped gate plate of the swinging anti-breaking gate, without spillage.

[0027] Since there is no weighing bin, other weighing methods are needed to measure the quantity of goods loaded. This embodiment adopts the monitoring and measurement method of a platform scale, that is, monitoring the weight throughout the loading process from the empty vehicle entering to the full vehicle driving out. Although the platform scale monitoring is simple and reliable, how to accurately control the weight of the coke entering the carriage is a rather tricky problem.

[0028] This embodiment adopts a simple method. A material-cutting gate is set at the position where the coke flows out of the swing anti-crushing gate. Once the loading reaches the required loading amount, the material-cutting gate is immediately closed so that the material in the carriage just reaches the required weight. The material-cutting gate is installed at the end of the dustpan-shaped gate plate of the swing anti-crushing gate. At the beginning of unloading, it moves together with the swing anti-crushing gate and is fully opened. It only moves at the end of loading to cut the material, and then it is lifted together with the swing anti-crushing gate. Figure 3 The position shown by the dotted line.

[0029] In order to solve the problem of a large amount of dust generated during the coke loading process and affecting the surrounding environment, this embodiment sets a closed dust cover at the loading station. The closed dust cover is provided with an automatic entry door and an exit door. The automatic opening of the door can adopt a conventional automatic door opening device without being connected to a controller. Alternatively, a special vehicle sensor is set to control the opening and closing of the automatic door. A dust suction device can be set in the closed dust cover to collect the dust generated by the coke loading to avoid affecting the surrounding environment and the health of the staff.

[0030] The controller is an electronic device with storage and computing capabilities, usually an industrial computer, PLC, etc. The controller controls the loading process of the belt conveyor, chute, drag device, various gates, etc. of the loading station through a set of control software formed by the loading process method. The electrical connection between the controller and the belt means that the controller is connected to the frequency converter of the belt conveyor to control the power of the belt conveyor and adjust the conveying capacity of the belt conveyor. The electrical connection between the controller and the chute means that the controller is connected to the electronic control device of the hydraulic cylinder of the chute to control the movement of the hydraulic cylinder through electrical signals. The electrical connection between the controller and each gate means that the controller is connected to the electronic control device of the hydraulic cylinder or hydraulic motor of each gate. Under normal circumstances, the controller is connected to the host computer, which can be a computer of the coke transportation department or sales department to provide some basic information of loading, including: information of the loaded vehicle and information such as the loading volume and particle size of coke.

[0031] Embodiment 2:

[0032] This embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment regarding the closed dust cover. The dust removal device described in this embodiment is arranged on the top of the closed dust cover, and includes: a dust cover 803, and the dust cover is connected to the dust collector 805 through a pipe 804, such as Figure 1 shown.

[0033] The dust collector is installed on the top of the closed dust cover, which is convenient for connecting the pipeline. The dust collector is similar to a vacuum cleaner, which uses a vacuum pump to generate strong suction to absorb the dust generated by loading.

[0034] Embodiment three:

[0035] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the cut-off and discharge arc gate. The cut-off and discharge arc gate described in this embodiment includes: a gate channel 401. An arc gate shaft 402 is provided at the bottom of the cut-off and discharge arc gate channel. The arc gate shaft is horizontally installed, and the central axis of the arc gate shaft is perpendicular to the vehicle running direction. A swing rod 403 driven by a hydraulic cylinder or a hydraulic motor and capable of swinging around the arc gate shaft is provided on the arc gate shaft. The swing rod is fixedly connected to an arc gate plate 404, as Figure 3 shown.

[0036] The extrusion force on the gate plate when the swing arc gate is opened ( Figure 3 shown by the solid line in Figure 3 ) and closed (

[0037] shown by the dashed line in

[0038] ) is much smaller than that of a flat gate, which has great advantages for materials with large frictional resistance such as coke. The swing rod can be rotated on the gate shaft by a hydraulic motor or a hydraulic cylinder. The swing rod is divided into left and right sides, and the top is connected to both sides of the arc gate plate to make the overall gate stable and safe. Figure 3 shown.

[0039] The telescopic chute described in this embodiment adopts a vertical lifting form, which has a simple structure and is not prone to failure.

[0040] Embodiment Five:

[0041] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the swing anti-breakage gate. The swing anti-breakage gate described in this embodiment includes: a swing gate shaft 601 installed at the bottom of the fixed cylinder of the telescopic chute. A grooved gate plate 602 driven by a hydraulic cylinder or a hydraulic motor and capable of swinging around the swing gate shaft is installed on the swing gate shaft. A cut-off gate is provided at the discharge end of the grooved gate plate, as Figure 3 shown.

[0042] The swing anti-breakage gate described in this embodiment is installed at the outlet of the chute to intercept a part of the falling material. The shape of the swing anti-breakage gate can be designed as a dustpan shape to store a small amount of coke. The purpose of storing a small amount of coke is that when the cut-off and discharge arc gate is opened, since the chute extends, the coke has a certain distance to fall. At this time, the swing anti-breakage gate has not been opened (in the Figure 3At the position of the dotted line described above), if there is a small amount of coke on the dustpan-shaped gate plate of the swinging anti-breakage gate, the carbon remaining in this coke will play a buffering role for the falling coke, thereby reducing the breakage of the coke.

[0043] Example Six:

[0044] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the groove-shaped gate plate. The groove-shaped gate plate described in this embodiment includes: a bottom plate 6021 and side plates 6022 installed on both sides of the bottom plate, as Figure 4 shown.

[0045] The groove-shaped gate plate with side plates on both sides in this embodiment forms a dustpan shape for the gate plate to store a small amount of coke to buffer the falling coke particles.

[0046] Example Seven:

[0047] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the material cutting gate. The material cutting gate described in this embodiment includes: a material cutting gate shaft 701 installed at the end of the bottom plate of the groove-shaped gate plate. A sector-shaped swinging plate 702 that can swing around the material cutting gate shaft driven by a hydraulic cylinder or a hydraulic motor is provided on the material cutting gate shaft. The sector-shaped swinging plate is fixedly connected to an arc-shaped material cutting plate 703, as Figure 3 shown.

[0048] The main function of the material cutting gate is to accurately intercept the material flow to make the loading amount reach a certain accuracy. The material cutting gate described in this embodiment adopts the form of a swinging gate, mainly to reduce the frictional resistance of the coke with gaps and is also convenient for design and installation.

[0049] Example Eight:

[0050] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the vehicle dragging device. The vehicle dragging device described in this embodiment includes: a dragging motor 901. The dragging motor drives a pallet 903 carrying the vehicle through a steel cable 902. A plurality of rollers 904 that move with the pallet are provided at the bottom of the pallet, as Figure 1 shown.

[0051] The vehicle dragging device described in this embodiment adopts a simple roller method, that is, rollers are arranged in rows under a flat plate, and the moving power of the pallet is driven by a motor to drive a winch and a steel cable to pull the pallet. The vehicle only needs to park on the pallet and can move with the pallet to form the displacement during loading, so that the coke is evenly stacked in the carriage.

[0052] Example Nine:

[0053] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the weighbridge. The weighbridge described in this embodiment includes: a weighing plate 1001, and a plurality of weighing sensors 1002 are evenly distributed at the bottom of the weighing plate, as Figure 1 shown.

[0054] The weighing plate is a flat plate that occupies the entire loading position. From the start to the end of loading, it is carried out on this flat plate. Therefore, weighing sensors are evenly arranged at the lower part of the flat plate. The weighing sensors can be arranged in a vertical and horizontal grid pattern or staggered and evenly arranged so as to be able to evenly measure the gravity of the entire vehicle and the loaded coke.

[0055] Embodiment Ten:

[0056] This embodiment is a drag-type coke environmental protection quantitative loading method using the equipment described in the above embodiment. The method can use an electronic control system at the loading station as a software program to control the loading station to carry out automatic loading. The specific steps of the method are as follows, and the process is as Figure 5 shown:

[0057] Step 1, feeding: The belt conveyor conveys coke into the silo for temporary storage. During the loading process, the silo should maintain the loading volume of 1 - 2 vehicles.

[0058] Before loading, it is necessary to obtain the information of vehicle loading, including: the size of the carriage, the loading volume this time, the particle size of coke, etc., and calculate the stacking height of coke in the carriage so that the coke stacked in the carriage does not exceed the height of the carriage side board and can be evenly spread in the carriage to avoid partial load.

[0059] Step 2, the vehicle enters the loading position: The automatic access door opens, the vehicle drives onto the pallet at the initial end, and the front end of the carriage is aligned with the position directly below the chute in the initial state, stops and parks. The weighing sensors of the weighbridge start to monitor the weight change on the pallet and record the weight of the empty vehicle.

[0060] The initial position of the pallet refers to the position where the pallet is closest to the automatic access door ( Figure 1 in which the pallet is in the initial position, and the dotted line represents the final position of the pallet). After the loading vehicle enters, it immediately drives onto the pallet. When the vehicle completely enters the pallet, the front part of the carriage should be aligned with the outlet of the chute.

[0061] Step 3, start the chute: The chute extends downward from the initial position. During the extension process, the intercepting and discharging arc-shaped gate is opened to allow coke to enter the chute, and at the same time, the dust collector is started.

[0062] The initial position of the chute refers to the position where the telescopic cylinder of the telescopic chute is completely retracted into the fixed cylinder, as Figure 1 shown in the implementation, Figure 1The dotted line in [it] indicates the state where the telescopic cylinder is fully extended.

[0063] Step 4, discharging: When the telescopic cylinder of the chute approaches the carriage floor, open the swing anti-breakage gate and the cut-off gate, so that the coke accumulates at the front end of the carriage. As the height of the accumulation increases, the chute retracts, increasing the height of the material pile to a suitable loading height. Start the vehicle towing device, and the vehicle moves slowly forward with the pallet, so that the material pile accumulates evenly in the carriage.

[0064] When the telescopic cylinder of the chute extends to the longest, the swing anti-breakage gate and the cut-off gate are opened. At this time, the swing anti-breakage gate is like an inclined chute, and the coke can slide down along the inclined chute into the carriage and accumulate. The accumulation height of the coke in the carriage has been calculated in advance by the controller. Usually, due to the relatively small specific gravity of the coke, the coke has to be piled up to the height of the carriage side panel.

[0065] Step 5, terminating discharging: When the weighing sensor of the weighbridge detects that the amount of coke entering the carriage is close to the required loading amount, reduce the opening of the cut-off and discharging arc gate. When the required loading amount is reached, close the cut-off gate, and then close the swing anti-breakage gate and the cut-off and discharging arc gate.

[0066] Before stopping discharging, the outlet of the chute should have reached the rear of the carriage, and the outlet of the swing anti-breakage gate is also at the top of the material pile. When approaching to fill the vehicle, first reduce the opening of the cut-off and discharging arc gate, and then gradually close this gate, so that the coke in the silo no longer enters the chute. However, there is still a small amount of coke in the chute and it can continue to discharge into the carriage. At this time, once the sensor sends out that the loading amount has reached the requirement, immediately close the cut-off gate, so that the coke in the chute no longer continues to fall into the carriage, accurately controlling the loading amount.

[0067] Step 6, ending loading: The chute retracts to the initial position, and at the same time, the pallet reaches the end position. The vehicle releases the parking brake and drives away from the pallet, then drives out through the automatic exit door. The pallet returns to the initial position, preparing for the next round of loading.

[0068] Due to the different lengths of the vehicles, when the loading and unloading are completed, the pallet does not necessarily reach the end position. When the carriage is short, after the loading and unloading are completed, the pallet still has to move forward until the end ( Figure 1 the position of the dotted line of the pallet in [it]), the vehicle can drive away from the pallet and drive out through the automatic exit door to complete the loading. Since the dust during the coke loading is very serious and the vehicle driving process will cause dust, after the vehicle drives out of the automatic exit door, if there is no next loading operation, the dust collector can be closed.

[0069] Finally, it should be noted that the above is only used to illustrate the technical solution of the present utility model and not to limit it. Although the present utility model has been described in detail with reference to the preferred layout, those of ordinary skill in the art should understand that the technical solution of the present utility model (such as the overall layout of the loading station, the metering and conveying speed of materials, the process of automatic control, the sequence of steps, etc.) can be modified or equivalently replaced without departing from the spirit and scope of the technical solution of the present utility model.
