Description

Technical Field

[0001] This utility model relates to the field of unblocking devices, specifically to an anti-clogging unblocking device for coking coal blending silos. Background Technology

[0002] Coal blending silos are key pieces of equipment used in industries such as coking and steel for storing and blending coking coal. Their core function is to achieve homogeneous storage and continuous, stable supply of coal. These silos typically consist of a steel structure silo, a conical discharge section, a feeding mechanism, and a supporting control system. The silo capacity is designed according to production scale and can store raw materials such as washed coal, coking coal, and coking coal in different proportions. After receiving coal through the top inlet, gravity causes the coal flow to naturally converge at the conical section, and a vibrating feeder or screw conveyor is used to achieve quantitative discharge.

[0003] In coking production, coal blending bins are used to store and transport coking coal. However, due to high coal moisture content, uneven particle size, or structural design defects in the bins, bridging or blockage can easily occur at the conical discharge section, discharge port, and other locations, leading to interruption of material supply and affecting production efficiency. Existing unblocking methods (such as manual tapping and vibrators) have problems such as low efficiency, poor safety, and easy damage to the bins. Therefore, there is an urgent need for an automated, efficient, and reliable unblocking device. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-clogging coking coal blending silo unblocking device to solve the following technical problems:

[0005] How to prevent blockages in the coal mixing silo during coal delivery.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A clog-resistant coking coal blending silo unblocking device includes a silo body and further includes:

[0008] The unblocking mechanism is located inside the chamber and includes a rotary stirring mechanism and a drive mechanism for driving the rotary stirring mechanism to rotate.

[0009] The vibration mechanism is located inside the silo and is used to drive the silo to vibrate.

[0010] In a further embodiment of this utility model: the rotary stirring mechanism includes a main shaft, the rear end of which is connected to a drive mechanism, and the front end extends to the inlet of the chamber; multiple layers of spiral blades are installed on the shaft wall of the main shaft.

[0011] In a further embodiment of this utility model: the driving mechanism includes a drive motor and a motor bracket mounted on the inner wall of the chamber. The drive motor is fixedly mounted on the motor frame, and the output shaft of the drive motor is connected to the main shaft.

[0012] In a further embodiment of this invention: the multi-layer helical blade includes a first helical blade assembly mounted on the front end shaft wall of the main shaft and a second helical blade assembly mounted on the rear end shaft wall of the main shaft.

[0013] In a further embodiment of this invention: the first helical blade assembly includes multiple sets of blades, each blade surface is provided with a first protrusion and a second protrusion, and one end of the first protrusion and the second protrusion is provided with a chamfer structure.

[0018] In a further embodiment of this invention: a pressure sensor is embedded at the front end of the spindle, and the pressure sensor is communicatively connected to the drive motor and the vibration motor.

[0019] The beneficial effects of this utility model are:

[0020] This utility model's anti-blockage coking coal blending silo unblocking device uses a built-in pressure sensor to collect pressure data in real time when the pressure in the silo rises abnormally due to bridging or accumulation of coking coal. The data is compared with a preset safety threshold. Once the pressure exceeds the limit, the pressure sensor immediately sends a trigger signal to the central control system. The system then simultaneously starts the vibration motor and the drive motor. The vibration motor breaks down the coal's adhesive structure through low-frequency, high-amplitude vibration, while the drive motor rotates the spiral blade assembly to mechanically crush and forcefully push the blocked coal blocks. With the synergistic effect of the two motors, the blocked parts of the silo can be quickly loosened and discharged to restore the continuity of the material supply. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0030] Please see Figure 1-2This embodiment discloses an anti-clogging coking coal blending silo unblocking device, including a silo body 100, with the left end of the silo body 100 being the inlet end and the right end being the outlet end. An unblocking mechanism 200 and a vibration mechanism are installed inside the silo body 100, wherein the unblocking mechanism 200 is located at the inlet end of the silo body 100 and the vibration mechanism is located at the outlet end of the silo body 100.

[0031] The unblocking mechanism 200 consists of a stirring and rotating mechanism and a driving mechanism. The stirring and rotating mechanism is connected to the driving end of the driving mechanism, which can realize rotational stirring, thereby stirring and crushing the coal at the inlet end of the silo 100, thus avoiding the coal from becoming blocked in the silo 100.

[0032] Please see Figure 3-4 The drive mechanism includes a drive motor 201 and a motor frame 202 supported outside the drive motor 201. The drive motor 201 is located inside the bin 100, and its outer wall is provided with a protective shell to prevent coal from entering the drive motor 201 and causing damage. The motor frame 202 is composed of three support rods, which are evenly distributed around the shell on the outer wall of the drive motor 201. One end of each support rod is fixedly connected to the shell, and the other end is fixedly connected to the inner wall of the bin 100. The support method of the three support rods can not only effectively support the drive motor 201, but also ensure that the coal has sufficient passage space.

[0033] It should be noted that in other embodiments, the drive motor 201 in the drive mechanism can also adopt other rotary drive devices or structures, as long as it can drive the stirring rotary mechanism to rotate; similarly, the specific structure of the motor frame 202 is not limited to the "three support rods" in this embodiment. In other embodiments, any design structure that can support the drive device or structure and ensure that the coal has sufficient space to pass through is allowed.

[0034] The stirring and rotating mechanism includes a main shaft 203, a first helical blade assembly 204, and a second helical blade assembly 205. The rear end of the main shaft 203 is connected to a drive motor 201, and the front end extends to the inlet end of the chamber 100. The first helical blade assembly 204 consists of multiple sets of blades arranged around the front end shaft wall of the main shaft 203 (first layer), with the helical direction from back to front. Each blade has a first protrusion 208 and a second protrusion 209 on its front surface, and the outer ends of the first protrusion 208 and the second protrusion 209 have sharp chamfered structures. The second helical blade assembly 205 also consists of multiple sets of blades arranged around the rear end shaft wall of the main shaft 203 (second layer), with the helical direction from front to back. Each blade has a third protrusion 210 on its front surface, and the outer end of the third protrusion 210 has a smooth structure.

[0035] Specifically, when a blockage occurs, the drive motor 201 starts, driving the main shaft 203 to rotate, which in turn drives the first helical blade assembly 204 and the second helical blade assembly 205 to rotate. The first helical blade assembly 204 breaks up the blocked coal. The first protrusion 208 and the second protrusion 209 on its surface increase the contact area with the coal, and the sharp chamfer structure helps to improve the crushing force on the coal. At the same time, because its helical direction is from back to front, the large clumps of coal cannot move backward under its rotation and can only move at the front end of the first helical blade assembly 204 until they are broken into smaller pieces. Only then can they move towards the second helical blade assembly 205 through the gaps between the blades. The second helical blade assembly 205 then transports the coal that has been crushed by the first helical blade assembly 204 backward. At the same time, the third protrusion 210 on its surface increases the contact area with the coal during the conveying process, increasing the friction between the coal and the coal. This is beneficial for both further crushing of the coal and for the conveying of the coal.

[0036] It should be noted that the number of layers in the helical blade assembly is not limited to the two layers (first helical blade assembly 204 and second helical blade assembly 205) in this application. In other embodiments, depending on the size of the bin 100 and the mass of the coal, the number of layers in the helical blade assembly can be set to 3, 4, 5, etc.

[0037] The vibration mechanism consists of three sets of vibration motors 300 evenly distributed at the outlet of the bin 100. The vibration motors 300 are installed on the inner wall of the bin 100. When the vibration motors 300 are started, the bin 100 can be vibrated, thereby causing high-frequency vibration of the coal inside. This vibration, combined with the crushing and transmission of the first spiral blade assembly 204 and the second spiral blade assembly 205, can make the coal continuously loose during the pushing process, avoiding secondary blockage.

[0038] An arch-breaking head 206 is fixedly connected to the front end of the main shaft 203 for pre-crushing the coal blocks at the front end of the bin 100. The structure of the arch-breaking head 206 is not specifically limited, and any structure that can pre-crush the coal is allowed. For example, in this embodiment, the arch-breaking head 206 is composed of six sets of blades surrounding the end of the main shaft 203, which can pre-crush the coal blocks before they are crushed by the first spiral blade assembly 204.

[0039] A pressure sensor 207 is also embedded in the front end of the spindle 203. The pressure sensor 207 is located between the six blades of the arch-breaking head 206. The pressure sensor 207, the drive motor 201, and the vibration motor 300 are all connected to the central control system. The pressure sensor 207 senses the pressure signal. When the pressure signal reaches the threshold, it sends a signal to the central control system. The central control system then sends a start signal to the drive motor 201 and the vibration motor 300, commanding them to enter the working state.

[0040] The working principle of this utility model:

[0041] When the silo 100 is in the coal conveying state, the pressure sensor 207 senses the pressure signal. When the pressure signal reaches the threshold, it sends a start signal to the drive motor 201 and the vibration motor 300, causing them to enter the working state. Specifically, the drive motor 201 drives the main shaft 203 to rotate, which in turn drives the arch-breaking head 206, the first spiral blade assembly 204, and the second spiral blade assembly 205 to rotate. The arch-breaking head 206 pre-crushes the coal blocks at the inlet end of the silo 100. After being crushed by the first spiral blade assembly 204, the coal blocks are formed into small-volume coal materials, which move towards the second spiral blade assembly 205 through the gaps between the blades, solving the blockage problem. The second spiral blade assembly 205 then transports the coal materials crushed by the first spiral blade assembly 204 backward. At the same time, combined with the high-frequency vibration of the vibration motor 300, the coal materials can be continuously loosened during the pushing process to avoid secondary blockage.
