Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal technology, and in particular to a dust removal device for the production of unshaped refractory materials. Background Technology
[0002] In the production of monolithic refractory materials, dust is a significant factor affecting the working environment and the health of operators. Traditional dust control methods typically include localized ventilation systems or simple hood coverings. While these methods can reduce dust dispersion to some extent, their effectiveness is often limited, especially in operations that generate large amounts of dust, such as crushing and mixing. First, localized ventilation systems usually require individual installation for each production piece of equipment, increasing equipment costs and making maintenance difficult due to their complex layout. Second, simple hood coverings, lacking effective sealing measures, cannot completely prevent dust from escaping and cause inconvenience to the operation of production equipment, reducing work efficiency.
[0003] Furthermore, existing dust collection devices generally lack flexibility and adaptability. For example, fixed hoods cannot be quickly adjusted according to the needs of the production process, which is not conducive to daily production operations, nor to equipment inspection and maintenance. When it is necessary to inspect or repair production equipment, it is often necessary to dismantle part or even all of the dust collection equipment, which is not only time-consuming but also increases the intensity of manual labor. Moreover, traditional dust collection devices usually use only a single filtration method, such as bag filters, when dealing with dust-laden airflow. This method is prone to rapid clogging of the filter media due to excessive dust load, thereby shortening the service life of the filter media and reducing dust collection efficiency.
[0004] Therefore, there is an urgent need for a dust removal device that can effectively solve the above problems, achieving efficient dust removal while ensuring operability and ease of maintenance, extending the service life of key dust removal components, and reducing operating costs. This new type of dust removal device should be mobile to adapt to different production scenarios and effectively separate dust from the dust-laden airflow, ensuring a safe and clean working environment. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a dust removal device for the production of unshaped refractory materials.
[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A dust removal device for the production of monolithic refractory materials includes: track; The movable cover is installed on a track and can move forward and backward along the track; the front of the movable cover is open and a fan is installed on its top. Mounting bracket, installed on one side of the movable cover; Cyclone separator, mounted on a mounting bracket; A connecting pipe is installed between the movable cover and the air inlet of the cyclone separator; it is used to connect the air inlet of the cyclone separator with the air outlet of the fan. A flexible tube is installed at the air outlet of the cyclone separator.
[0007] Preferably, the movable cover includes: Framework; A conical shroud is installed on top of the frame, and a fan is installed inside it; There are three baffles, which are detachably connected to the left, right and rear sides of the frame respectively; There are four wheels, which are installed at the four corners of the bottom of the frame; the wheels are compatible with the track.
[0008] Preferably, the mounting bracket is securely connected to the frame body, with a gap between them.
[0009] Preferably, a flexible curtain is installed on the front side of the movable cover.
[0010] Preferably, flexible baffles are installed on the left, right and rear sides of the movable cover.
[0011] Preferably, a discharge device is installed at the bottom of the dust collection bin of the cyclone separator.
[0012] By adopting the technical solution described above, this utility model has the following beneficial effects: (1) This utility model has a simple structure. By setting parallel tracks and a movable cover that can move along the tracks, it achieves flexible coverage of production equipment for monolithic refractory materials such as crushers and mixers. The movable cover has the function of moving back and forth along the tracks. When it is necessary to inspect the equipment, replace parts, or carry out hoisting operations, it can be moved backward as a whole to fully expose the equipment and avoid the cover blocking the maintenance passage, thereby improving maintenance efficiency and operational safety. This structure can quickly switch between production and maintenance modes without disassembling the cover, taking into account both dust removal function and equipment maintainability, and effectively solving the contradiction between the traditional fixed dust removal cover and the difficulty in balancing sealing and ease of operation.
[0013] (2) The cyclone separator of this utility model performs primary separation of dust-laden airflow through inertial centrifugal force, which can efficiently capture most of the dust particles, significantly reduce the dust load of the subsequent exhaust system, extend the service life of the filter material, and improve the overall dust removal system's operational stability.
[0014] (3) The movable cover of this utility model is further optimized into a modular structure consisting of a frame, a conical cover, detachable baffles, and wheels. The top of the conical cover has a built-in fan, and its conical structure helps to guide the airflow upward and concentrate it, improving dust collection efficiency and reducing dust accumulation on the top of the cover. The baffles on the left, right, and rear sides are connected by bolts or clips, and can be selectively removed according to local maintenance needs, without having to move the entire cover, saving operation time and reducing labor intensity. In addition, the flexible curtain set on the front side effectively suppresses dust escape without obstructing the passage of materials or equipment, while the flexible baffles on the left, right, and rear sides fit the gaps, further enhancing the overall sealing performance, reducing dust leakage from the edges, and improving the dust removal effect.
[0015] (4) This utility model further adds a discharge device at the bottom of the dust collection bin of the cyclone separator, and adopts mature structures such as star-shaped discharge valve or screw conveyor device to achieve continuous and quantitative discharge of dust while maintaining negative pressure inside the system. This design avoids the risk of blockage caused by dust accumulation in the dust collection bin, ensures stable cyclone separation efficiency, reduces the frequency of manual dust cleaning, improves the system's automation level and continuous operation capability, and helps maintain a stable production rhythm.

[0018] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0019] In the description of this utility model, it should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use. They are only used to facilitate the description of this utility model and to simplify 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.
[0020] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0021] Example 1: Combined with appendix Figures 1-3 A dust removal device for the production of monolithic refractory materials includes a track 1, a movable hood 2, and a cyclone separator 4. Two tracks 1 are spaced apart and arranged parallel to each other on the ground on both sides of the crushing or mixing equipment, supporting and guiding the movable hood 2 to move along its length. The movable hood 2, which has a box-like structure, is installed on the track 1 and can cover the outside of the crusher, mixer, or other monolithic refractory material production equipment, forming a partially enclosed space. This effectively prevents dust from overflowing during material crushing, mixing, and transfer, thereby reducing dust concentration in the workshop, improving the working environment, and reducing health hazards to operators. The movable hood 2 can move forward or backward along the track 1, allowing for adjustment of its coverage position according to production or maintenance needs.
[0022] The movable hood 2 has an open front to facilitate material loading and unloading and equipment operation. A fan is fixedly installed at the top inside; when the fan operates, it creates a negative pressure zone within the hood, causing dust to concentrate inside and be discharged through the fan. When maintenance, component replacement, or hoisting operations are required for the crushing or mixing equipment, the movable hood 2 can be moved backward along track 1, fully exposing the equipment to the external space. This prevents the hood from obstructing the maintenance passage, improving maintenance efficiency and operational safety. This structural design balances dust removal functionality with equipment maintainability, allowing for quick switching of operating modes without additional hood disassembly.
[0023] A mounting bracket 3 is fixedly installed on one side of the movable hood 2. This bracket supports the cyclone separator 4, ensuring its stable operation. The cyclone separator 4 uses inertial centrifugal force to perform primary separation of the dust-laden airflow, separating and collecting most of the dust particles from the airflow. This significantly reduces the dust load on the subsequent exhaust system, extends the service life of the filter media, and improves the overall dust removal efficiency. A connecting pipe 5 is provided between the movable hood 2 and the air inlet of the cyclone separator 4. One end of the connecting pipe 5 is sealed to the air outlet of the top fan inside the movable hood 2, and the other end is connected to the air inlet of the cyclone separator 4, forming a complete airflow channel to ensure that the dust-laden gas is efficiently introduced into the cyclone separator 4 for treatment.
[0024] A flexible tube 6 is connected to the outlet end of the cyclone separator 4. This flexible tube 6 is made of wear-resistant and aging-resistant flexible material, with good bending adaptability and sealing performance. It can guide the clean airflow after cyclone separation to the outside of the workshop for discharge, or connect to the inlet of the bag filter dust collector outside the workshop, avoiding secondary pollution of the air in the working area. At the same time, the flexible structure of the flexible tube 6 can adapt to slight displacement or vibration during equipment operation, ensuring connection reliability and preventing air leakage caused by loosening of the interface.
[0025] Example 2: Combined with appendix Figure 1 and 4 A dust removal device for the production of monolithic refractory materials is disclosed, which further optimizes the structure of the movable hood 2 based on Embodiment 1. The movable hood 2 includes a frame body 2-1, a conical hood 2-2, baffles 2-3, and wheels 2-4. The frame body 2-1 is welded from structural steel and constitutes the main support structure of the movable hood 2; the conical hood 2-2 is fixedly installed on its top, and a fan is installed inside the conical hood 2-2. The conical structure helps to guide the airflow upward and concentrate it, improving the dust collection efficiency of the fan and reducing the accumulation of dust on the top of the hood.
[0026] Baffles 2-3 are detachably connected to the left, right, and rear sides of the frame 2-1 via bolts or clips. The baffles 2-3 are made of steel plate or composite material, providing good sealing and structural strength. During daily production, the baffles 2-3 remain installed, forming a closed or semi-closed dust removal space together with the conical hood 2-2. When only a localized area of the equipment needs inspection or minor maintenance, the corresponding baffles 2-3 can be selectively removed without moving the entire movable hood 2, thus saving operation time and reducing labor intensity.
[0027] The frame 2-1 is equipped with four corner wheels 2-4 at its bottom. The wheels 2-4 are load-bearing wheels with bearings and match the rail surface of the track 1 to ensure that the movable cover 2 moves smoothly and stably and is not prone to derailment.
[0028] Furthermore, the mounting bracket 3 is bolted to the frame 2-1, with an appropriate gap between them. This gap allows for the removal of the baffle 2-3 on the side of the frame 2-1 closest to the mounting bracket 3 when needed, preventing the mounting bracket 3 from interfering with the installation and removal of the baffle 2-3 and improving maintenance convenience. In addition, a flexible curtain 2-5 is installed at the front opening of the movable cover 2. Made of multiple layers of wear-resistant rubber or PVC material, the flexible curtain 2-5 hangs over the front opening, effectively blocking dust escape without hindering material entry and exit, while allowing forklifts and other equipment to pass freely. Flexible baffles 2-6 are also provided on the left, right, and rear edges of the movable cover 2. These baffles fit into the gaps between the baffle 2-3 and the ground or equipment, further enhancing the sealing effect, reducing dust leakage from side gaps, and improving the overall airtightness of the dust removal system.
[0029] Example 3: Combined with appendix Figure 1 A dust removal device for the production of monolithic refractory materials is disclosed, which improves the dust removal structure of the cyclone separator 4 based on Embodiment 1 or Embodiment 2. A discharge device 7 is installed at the bottom of the dust collection bin of the cyclone separator 4. The discharge device 7 is a commonly used star-shaped discharge valve or screw conveyor in the prior art, which is a mature and reliable ash removal device. The function of the discharge device 7 is to continuously and quantitatively discharge the separated dust to the collection container or conveying system while maintaining the negative pressure state inside the cyclone separator 4, avoiding dust accumulation in the dust collection bin that could cause blockage or affect separation efficiency. This structure ensures that the dust removal system can operate continuously for a long time, reduces the frequency of manual cleaning, improves the level of automation, and ensures the stability of the production rhythm.
[0030] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
