Description

Technical Field

[0001] This utility model relates to the field of material conveying and processing equipment technology, and in particular to an automatic material feeding device embedded in the silo wall. Background Technology

[0002] In industrial sectors such as carbon production, materials, after undergoing processes like calcination, need to be stored in large calcined silos and then transferred out as needed for production. Traditional discharge devices are typically located directly below the silo, using pneumatic valves or similar mechanisms. However, this layout has inherent drawbacks: many early silos were not designed with the subsequent material transfer needs in mind, resulting in limited space at the bottom and insufficient height, preventing large transport vehicles from entering and making material transfer extremely inconvenient.

[0003] To address this space constraint, an alternative solution is to create an outlet on the side wall of the silo and install a simple discharge chute. However, this simple device has revealed new problems in use: First, the chute outlet is usually located high and fixed, and the material falling from a height has high kinetic energy, easily causing splashing and spillage, resulting in material loss and on-site pollution; second, the huge drop causes a large amount of dust to be generated during the impact and flow of the material, seriously deteriorating the working environment, threatening the health of operators, and posing environmental risks; finally, in order to control the material flow, these devices often use manual slide valves, requiring operators to use long poles and other tools for frequent and laborious operation, which is not only labor-intensive but also makes it difficult to accurately control the material flow.

[0004] Therefore, the market urgently needs a new type of material discharge device that can break through the space limitations at the bottom of the original silo, achieve automated control, and effectively suppress dust and material spillage during the discharge process. Utility Model Content

[0005] In view of this, this application provides an externally embedded automatic material discharging device for silos. The main purpose is to solve the technical problem in the prior art that it is impossible to achieve a reasonable structural layout while realizing one-button automatic material discharging and minimizing dust and material spillage.

[0006] This utility model provides an externally embedded automatic material discharging device for discharging material from a silo to the outside. The device includes a discharge pipe and a valve for controlling the opening and closing of the discharge pipe. The device further includes: a vertically movable telescopic sleeve connected to the discharge pipe; a lifting mechanism for driving the telescopic sleeve to move vertically; a material level switch located at the lower end of the telescopic sleeve; and a control system electrically connected to the valve, the lifting mechanism, and the material level switch. When the control system receives a signal from the material level switch indicating that it has come into contact with accumulated material below, it controls the lifting mechanism to drive the telescopic sleeve upwards.

[0007] As a further optimization of this solution, the control system is also configured such that, after the telescopic sleeve is lifted upwards, if the material level switch disengages from the material, the control system controls the lifting mechanism to stop lifting the telescopic sleeve and waits for the next trigger. This "contact-lift-stop" cyclical working mode constitutes the core function of the device: "material pile height following".

[0008] Furthermore, the lifting mechanism includes a gantry frame and an electric hoist mounted on the gantry frame. The electric hoist is connected to the telescopic sleeve, and the telescopic sleeve is suspended by the electric hoist. In this application, the lifting mechanism adopts a combination of a mature, stable, and reliable gantry frame and an electric hoist mounted on the gantry frame. The hook of the electric hoist is connected to the upper part of the telescopic sleeve via a hinge, cable, or chain.

[0009] Furthermore, the lifting mechanism also includes an upper limit switch, and when the control system receives a signal from the electric hoist that triggers the upper limit switch, it controls the valve to close.

[0010] Preferably, the valve is an electric slide gate valve that is easy to automate.

[0011] Furthermore, in order to further improve the environmental protection effect, the automatic feeding device is also equipped with a dust collection pipe. One end of the dust collection pipe is connected to the telescopic sleeve, and the other end is connected to the dust removal equipment, so as to actively remove and purify the dust generated during the feeding process.

[0012] Furthermore, the telescopic sleeve includes an inner tube for conveying materials and an outer tube sleeved outside the inner tube, the outer tube being used to collect dust and communicating with the dust collection pipe.

[0013] Furthermore, after receiving the material release start command, the control system first controls the lifting mechanism to drive the telescopic sleeve to descend to the predetermined position, and then controls the valve to open.

[0014] Furthermore, the automatic feeding device also includes a remote control controller for remotely sending the feeding start command to the control system.

[0015] Beneficial effects Compared with the prior art, this utility model has the following significant advantages: First, it realizes automatic follow-up of the material pile height, effectively suppressing dust. Specifically, by setting a material level switch at the bottom of the telescopic sleeve and interlocking it with the lifting mechanism, this application realizes that the outlet of the discharge pipe can automatically and stepwise follow the increase of the material pile below, ensuring that the falling height of the material is always controlled at the minimum value throughout the entire discharge process, which greatly suppresses the generation of dust and the splashing of materials from the source.

[0016] Second, it breaks through space limitations and has strong applicability. Specifically, the device of this application adopts the "embedded in the silo wall" design and is installed on the operating platform outside the silo, which completely solves the problem of insufficient space under the traditional silo and the inability of large vehicles to enter, and greatly improves the flexibility and efficiency of material transfer.

[0017] Third, this application achieves a high degree of automation and reduces labor intensity. Specifically, the entire material feeding process of this application, from the descent of the telescopic tube and the opening of the valve to the lifting with the material pile and the final closing of the valve, is automatically completed by the control system. There is no need for laborious manual operation, which significantly reduces labor intensity and improves production safety.

[0026] Example The following will be combined with the appendix Figure 1-2 The preferred embodiments of this utility model will be described in detail below.

[0027] Please see Figure 1 This utility model discloses an externally embedded automatic material discharging device for discharging material from a silo 14 to the outside. First, a sturdy operating platform 4 is built outside the predetermined material discharging position on the side wall of the silo 14, and a gantry frame 9 and a control cabinet containing a control system 6 are installed on the platform 4.

[0028] The automatic feeding device's feeding channel consists of a feeding pipe 3 extending from the wall of the hopper 14 and a telescopic sleeve 12 connected to it. A valve 1 is installed on the feeding pipe 3 to precisely control its opening and closing, thereby controlling the material channel's opening and closing. The telescopic sleeve 12 is composed of multiple nested pipe sections of different diameters, specifically including an inner pipe for conveying materials and an outer pipe sleeved outside the inner pipe. The outer pipe collects dust and is connected to the dust collection pipe 7. The telescopic sleeve 12 can extend or shorten vertically. At the lowest end of the telescopic sleeve 12, a level switch 2, such as a contact or non-contact level sensor, is installed.

[0029] In one feasible implementation, the lifting and lowering of the telescopic sleeve 12 is driven by a lifting mechanism. In this embodiment, the lifting mechanism consists of an electric hoist 8 mounted on a gantry frame 9. The hook of the electric hoist 8 is connected to the upper part of the telescopic sleeve 12 via a connecting component such as a hinge 13, and the telescopic sleeve 12 is suspended by the electric hoist 8.

[0030] In one feasible implementation, to achieve better dust removal effect, the device is also equipped with a dust collection system. The dust collection system includes a dust collection pipe 7. One end of the dust collection pipe 7 is connected to the upper part of the telescopic sleeve 12 through a dust collection hood 10, and the other end is connected to the main pipeline of the existing dust removal equipment 11 in the factory, thereby realizing the active extraction and purification of dust generated during the material discharge process.

[0031] In this embodiment, all electrical components, including valve 1, level switch 2, electric hoist 8, and possible upper limit switch, are electrically connected to the control system 6 in the control cabinet (e.g., a logic circuit composed of time relays, intermediate relays, AC contactors, etc., or a PLC controller).

[0032] In one feasible implementation, the working process and principle of the device in this application are described as follows: The automated workflow of this device is as follows: Step 1: The operator starts the material feeding program from the control cabinet or via remote control. At this time, the dust collection device 11 connected to the dust collection pipe 7 is in operation.

[0033] Step 2: After receiving the material release start command, the control system 6 first controls the lifting mechanism to drive the telescopic sleeve 12 down to a predetermined position, and then controls the valve 1 to open. Specifically, the control system 6 first controls the electric hoist 8 to start, releasing the telescopic sleeve 12, which is in a retracted state, downwards until it descends to the predetermined position, i.e., the lower end of the telescopic sleeve 12 is close to the ground or the receiving interface of the transport vehicle. This process can be controlled by a time relay delay or by positioning via a lower limit switch. In this embodiment, the device also includes a remote control controller for remotely sending the material release start command to the control system 6.

[0034] Step 3: When the lower end of the telescopic sleeve 12 is close to the ground or the receiving interface of the transport vehicle, the control system 6 issues a command to open the valve 1, and the material begins to flow out from the hopper 14 through the discharge pipe 3 and the telescopic sleeve 12, forming a material pile below.

[0035] Step 4: As material is continuously discharged, the material pile below gradually increases in height. When the top surface of the material pile touches the material level switch 2 at the lower end of the telescopic sleeve 12, the material level switch 2 is triggered and sends a signal to the control system 6.

[0036] Step 5: Upon receiving the signal, the control system 6 controls the lifting mechanism to drive the telescopic sleeve 12 upward. Specifically, the control system 6 immediately starts the electric hoist 8, thereby driving the telescopic sleeve 12 upward. When the telescopic sleeve 12 has risen a short distance, causing the material level switch 2 to disengage from the material pile, the control system 6 immediately stops the electric hoist 8, at which point the lifting action of the telescopic sleeve 12 pauses.

[0037] Step 6: The material continues to be released, the material pile rises again and touches the material level switch 2 again, and the process of step 5 will be repeated. In this cycle, the telescopic sleeve 12 realizes the step-like, automatic "follow-up" function of rising with the increase of the material pile height.

[0038] Step 7: When the control system receives a signal that the transport vehicle is full or the electric hoist 8 has been raised to its upper limit switch and triggered, the control system 6 will automatically close the valve 1, stop feeding, and may choose to completely retract the telescopic sleeve 12. At this point, a complete automatic feeding process ends.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
