Description

Technical Field

[0001] This utility model relates to the field of anti-blocking device technology, and in particular to an auxiliary unblocking device. Background Technology

[0002] In cement production, high-silica limestone refers to limestone with a relatively high silica (SiO2) content. Due to its high silica content, this type of limestone has certain application value in cement production. However, large reserves of high-silica limestone can restrict the overall quality of the ore; therefore, proper blending is necessary during raw material batching to maximize limestone utilization and reduce production costs.

[0003] The manufacturing plant uses high-silica silos for storage. However, since the raw material mill went into operation, the logistics system has frequently experienced blockages. This is due to the rainy season and high humidity, which results in high moisture content and large pieces of raw materials, as well as increased sludge usage. To address the issue of large material pieces, the branch plant added 20cm*20cm steel gratings to the discharge port of each scale. While this solved the problem of large pieces, it made material discharge difficult, caused rapid and easy crusting, frequent material blockages, and large fluctuations in mill operation, resulting in insufficient mill output and high overall power consumption. This necessitated personnel to be stationed at the steel grating for cleaning, which increased the workload of on-site personnel and made cleaning more difficult. Safety during the cleaning process was also uncontrollable, and there was a risk of damaging the conveyor belt during the cleaning process.

[0004] To address the issue of crusting at the discharge port, a vibrating motor is often added to the steel grating to increase the discharge speed and prevent blockages. However, the high vibration frequency of the steel grating causes raw materials in contact with it to easily fall out due to vibration, resulting in excessive material spillage and blockage of the high-silica silo's raw material outlet, thus affecting the discharge process.

[0005] Therefore, this application aims to solve the problem that raw materials in high-silicon silos are prone to falling out of the feed inlet when vibrating, while also avoiding the problem of blockage at the raw material inlet of high-silicon silos. Utility Model Content

[0006] The main purpose of this utility model is to provide an auxiliary unblocking device, which aims to solve the problem that raw materials in high-silicon silos are prone to falling out of the feed port when vibrating, and also to avoid the problem of blockage at the raw material port of high-silicon silos.

[0007] To achieve the above objectives, this utility model proposes an auxiliary unblocking device, comprising:

[0008] A sieve, with a recess in the middle for receiving raw materials;

[0009] Connecting seats are fixed at opposite ends of the screen.

[0010] A vibrating element, mounted on the connecting seat, generates a vibration force that is transmitted from the connecting seat to the screen; and

[0011] The support carries the connecting seat and is elastically connected to the connecting seat.

[0012] Furthermore, the screen includes several horizontal bars connected between a pair of connecting seats, and several connecting strips are fixed between the horizontal bars in sequence, with the bottom end of the connecting strips being hook-shaped.

[0013] Furthermore, the space between the horizontal bar and the connecting bar is provided with several support bars.

[0014] Furthermore, an elastic element is provided between the connecting seat and the support.

[0015] Furthermore, the elastic element is a spring.

[0016] Furthermore, the connecting seat also includes a mounting plate and a support block that are fixed to each other. The side wall of the mounting plate away from the screen is fixedly connected to the vibrating element, and the support bears the support block.

[0017] Furthermore, the mounting plate and the support block are integrally formed.

[0018] Furthermore, a limiting plate is also installed on the side wall of the support facing the screen, the limiting plate being used to block raw materials from the screen.

[0019] Furthermore, the support block is arc-shaped, and the side of the support facing the support block is also provided with a corresponding inclined surface, and the elastic element is connected between the inclined surface and the support block.

[0020] The above technical solution has the following advantages:

[0021] This invention features recesses on the screen mesh, which vibrate via a vibrating element. The recesses accommodate the raw material, causing it to gradually disperse under the influence of the vibrating element. This reduces the dispersion range of the raw material and prevents it from spilling outside the high-silica silo's feed inlet, thus avoiding blockage and disruption of the material feeding process.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0028] like Figure 1 and Figure 2 As shown, an auxiliary unblocking device includes a screen 5, a connecting seat 4, a vibrating element 3, and a support 1. The screen 5 has a recess in the middle for accommodating raw materials. The connecting seat 4 is fixed at opposite ends of the screen 5. The vibrating element 3 is disposed on the connecting seat 4, and the vibration force generated by it is transmitted from the connecting seat 4 to the screen 5. The support 1 supports the connecting seat 4 and is elastically connected to the connecting seat 4. The screen 5 is used to screen the raw materials in the high-silica silo, allowing the raw materials to fall gradually from the screen 5. The screen 5 has a depression in the middle, which blocks the raw materials as they fall. When the vibrator 3 vibrates, its vibration force is transmitted to the screen 5 through the connecting seat 4, causing the screen 5 to vibrate gradually and screen the raw materials in the depression of the screen 5. This clears the situation where large pieces of raw materials cannot fall from the high-silica silo, and at the same time, it can crush large pieces of materials. The depression of the screen 5 blocks the raw materials, and when the raw materials are screened in the depression of the screen 5, they fall left and right along the depression of the screen 5, thus achieving uniform falling of the raw materials. At the same time, it also prevents the raw materials from falling from the screen 5 to other positions and avoids the raw materials from falling into the raw material outlet of the high-silica silo, which would cause blockage in the raw material area of ​​the high-silica silo.

[0029] like Figure 2 and Figure 3 As shown, the screen 5 includes several horizontal bars 501 connected between a pair of connecting seats 4. Several connecting strips 502 are fixed between the horizontal bars 501 in sequence. The bottom end of the connecting strips 502 is hook-shaped. The recessed part of the screen 5 can be made of several horizontal bars 501. The horizontal bars 501 form a hook shape in cross-section. The connecting strips 502 form a mesh to accommodate the raw material falling from the high silica bin. The raw material falls at the lowest end of the mesh. With the use of the vibrating element 3, the raw material can be gradually scattered from the lowest end of the screen 5.

[0030] As a further effect, the space between the horizontal bar 501 and the connecting bar 502 is provided with several supports. At this time, the supports are not drawn in the figure. The supports only need to extend to the space. For example, they can be connected diagonally or on opposite sides, or they can extend from the side of the space.

[0031] like Figure 2 As shown, an elastic element 2 is also provided between the connecting seat 4 and the support 1. The elastic element 2 can be made of rubber or elastic sheet, preferably a spring. When the vibrating element 3 is started, the vibration force transmitted by the vibrating element 3 acts on the mounting plate 401. The mounting plate 401 drives the screen 5 to vibrate, thereby improving the efficiency of the raw material falling and avoiding the raw material from clogging at the screen 5. At the same time, in combination with the concave part of the screen 5, the overflow of raw material on the screen 5 can be further reduced.

[0032] like Figure 2 As shown, the connecting seat 4 also includes a mounting plate 401 and a support block 402 that are fixed to each other. The side wall of the mounting plate 401 away from the screen 5 is fixedly connected to the vibrating element 3. The support 1 supports the support block 402. The mounting plate 401 and the support block 402 are preferably integrally formed. The vibrating element 3 is installed on the side wall of the mounting plate 401. This space is completely exposed, which facilitates maintenance operations. The support block 402 is fixed to the elastic element 2. When the mounting block and the support block 402 vibrate, the vibration force can be effectively transmitted to the screen 5. The cooperation between the elastic element 2 and the support 1 can reduce the offset of the support 1.

[0033] The support block 402 is arc-shaped. The side of the support 1 facing the support block 402 is also provided with a corresponding inclined surface. The elastic element 2 is connected between the inclined surface and the support block 402. When the elastic element 2 is a spring, an inclined part 101 is also provided on the side of the support 1 facing the support block 402. The inclined part 101 is used to support one of the springs at an incline, ensuring that the spring is perpendicular to the support block 402. The spring is fixed to different arc-shaped surfaces of the support block 402 and applies fixed force to the support block 402 in three directions to ensure the stability of the position of the support block 402.

[0034] A limiting plate 403 is also installed on the side wall of the support 1 facing the screen 5. The limiting plate 403 is used to block the raw material from the screen 5. The blocking of the limiting plate 403 can prevent the raw material from falling into the spring through the gap between the support 1 and the connecting seat 4 when it falls, so as to avoid the spring from being blocked or stuck, which would affect the vibration force of the screen 5.

[0035] In the above method, the vibrating element 3 can be a vibrating motor or a vibrating motor.

[0036] The construction steps for the above scheme are as follows: dimensional measurement → steel grid fabrication → vibration motor installation → electrical control cabinet → wiring and debugging.

[0037] 1. The vibrating screen is installed at a 45-degree angle to quickly separate large pieces and clumps during operation, ensuring the material throughput.

[0038] 2. Electrical control adopts a central automatic control method.

[0039] 3. Weld all joints fully and cut and seal any holes in the protective cover to prevent leaks and spills that could pose environmental risks.

[0040] 4. The head protection cover is equipped with a 500cm*500cm material cleaning door for easy cleaning of accumulated materials later.

[0041] 5. After the hot air box and hot air pipes are manufactured, they are sanded and painted.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
