Description

Technical Field

[0001] This utility model relates to the field of weighing module technology, and in particular to a protective shell for a weighing module used in explosion-proof environments. Background Technology

[0002] In high-risk explosion-proof environments such as petrochemical and coal mining, weighing modules are key equipment for material metering and production process monitoring. Their protective enclosures must simultaneously meet the dual requirements of explosion protection and stable operation. To isolate external flammable and explosive gases and dust, traditional protective enclosures adopt a fully enclosed design, but neglect the construction of heat dissipation functions. As weighing modules continuously generate heat during long-term operation, the lack of a heat dissipation structure causes heat to accumulate in the confined space. This not only accelerates the aging of internal components but also affects measurement accuracy due to temperature changes, thereby interfering with production process control. In addition, existing protective enclosures adopt an integrated structure, which has significant drawbacks in installation and maintenance. During installation, the integrated enclosure needs to be fully adapted to the weighing module and the installation environment, which is complex and has a low fault tolerance. When internal components malfunction, maintenance personnel must disassemble the entire enclosure, which not only consumes a lot of time and manpower but also easily damages the sealing performance of the enclosure due to repeated disassembly and assembly, increasing safety hazards. Therefore, we have introduced a protective enclosure for weighing modules for explosion-proof environments. Utility Model Content

[0003] The main purpose of this utility model is to provide a protective shell for a weighing module for explosion-proof environments, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A protective housing for a weighing module for use in explosion-proof environments includes a weighing module mounting base. Each of the four corners of the upper end of the mounting base has a sleeve hole, and each of the four sleeve holes has a first screw hole on its lower inner wall. Two fixing blocks are fixedly connected to the front and rear ends of the mounting base. Each of the four fixing blocks has a through-hole at its upper end. A first protective component is movably fitted into the two sleeve holes on the front side, and a second protective component is movably fitted into the two sleeve holes on the rear side. Two bolts are threaded to the upper ends of both the first and second protective components. A heat dissipation component is fixedly fitted onto the first protective component.

[0006] Preferably, the first protective component includes a first protective housing body, a U-shaped sealing plate is fixedly connected to the rear edge of the first protective housing body, a plurality of sealing strips are fixedly connected to the outer periphery of the U-shaped sealing plate, an I-shaped slot with inward and outward penetration is opened at the front upper part of the first protective housing body, an I-shaped protective partition is movably engaged in the I-shaped slot, a handle is fixedly connected to the upper part of the I-shaped protective partition, a fixing groove with inward and outward penetration is opened at the front end of the first protective housing body, and first sleeve blocks are fixedly connected to the lower left and lower right parts of the first protective housing body, and a second screw hole with inward and outward penetration is opened at the upper end of each of the two first sleeve blocks.

[0007] By adopting the above technical solution, the I-shaped protective partition can be flexibly disassembled. When heat dissipation is required, it can be pulled out from the I-shaped slot by the handle to open the heat dissipation channel and achieve heat dissipation in conjunction with the heat dissipation components.

[0008] Preferably, the lower parts of the two first sleeve blocks are movably sleeved in the corresponding two sleeve holes, and the outer surfaces of the two front bolts are threaded to the inner walls of the corresponding two second screw holes and extend into the corresponding two first screw holes.

[0009] By adopting the above technical solution: the first sleeve block with movable connection makes the installation process of the first protective component and the weighing module fixing seat more convenient, can be quickly positioned, and reduces installation time and labor costs. The threaded connection method of the bolts passing through the second screw hole and the first screw hole in sequence can provide a stable and reliable fastening force.

[0010] Preferably, the second protective component includes a second protective housing body, a U-shaped sealing groove is formed at the front edge of the second protective housing body, a plurality of strip-shaped sealing grooves are formed on the outer ring of the inner wall of the U-shaped sealing groove, and a second sleeve block is fixedly connected to the lower left and lower right ends of the second protective housing body, and a third screw hole is formed at the upper end of each of the two second sleeve blocks.

[0011] Preferably, the lower parts of the two second sleeve blocks are movably sleeved in the corresponding two sleeve holes, and the outer surfaces of the two rear bolts are threaded to the inner walls of the corresponding two third screw holes and extend into the corresponding two first screw holes.

[0012] Preferably, the U-shaped sealing plate is movably engaged in the U-shaped sealing groove, and the plurality of sealing strips are respectively movably engaged in the corresponding plurality of strip-shaped sealing grooves.

[0013] By adopting the above technical solution, a multi-layer sealing barrier is formed. The U-shaped sealing plate and the U-shaped sealing groove fit together tightly. In addition, the sealing strip and the strip sealing groove are nested together, which can effectively prevent explosive gases, dust and other dangerous media from seeping into the shell. This creates a safe and stable working environment for the weighing module and greatly reduces the risk of explosion.

[0014] Preferably, the heat dissipation assembly includes a fixed frame, a dustproof mesh is embedded at the rear end of the fixed frame, and a plurality of heat dissipation guide plates are movably installed on the left and right inner walls of the fixed frame through a rotating shaft, and the fixed frame is fixedly sleeved in a fixed groove.

[0015] By adopting the above technical solution, the dustproof net embedded at the rear end of the fixed frame can effectively intercept external dust, prevent dust from entering the protective shell, and avoid dust accumulation affecting heat dissipation or damaging the weighing module.

[0016] Preferably, the heat dissipation guide plates are all inclined at the front-up and rear-down angles and are distributed at equal intervals in pairs.

[0017] By adopting the above technical solution, the tilt angle of front-up and rear-down can effectively guide the airflow direction, allowing heat to flow along the tilt direction of the heat dissipation guide plate, forming a smooth heat dissipation channel. The equidistant distribution of the two sides ensures uniform airflow inside the protective shell, allowing heat to be dissipated evenly.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this utility model, the outer shell adopts a split design. The first protective component and the second protective component are nested and matched with the U-shaped sealing plate and the U-shaped sealing groove, and are matched with the snap-fit ​​of several sealing strips and the strip sealing groove to form a multi-layer sealing barrier, which can effectively block the intrusion path of external explosive substances. Even in complex vibration or temperature and humidity change environment, the sealing components can still maintain a tight fit, ensuring that the weighing module operates stably in a safe environment.

[0020] 2. In this utility model, when the weighing module generates heat during operation, the handle on the I-shaped protective partition can be pulled out of the I-shaped slot to open the heat dissipation channel. At this time, the heat dissipation guide plate, which is inclined at the front and the back, uses the principle of aerodynamics to guide the airflow from the dustproof net at the rear end of the fixed frame into the module surface and carry away the heat. The dustproof net can simultaneously intercept external dust to avoid dust accumulation affecting the heat dissipation efficiency or damaging the internal components, thus achieving the dual functions of heat dissipation and dust prevention.

[0021] 3. In this utility model, the outer shell adopts a modular design. The first protective component and the second protective component are movably connected to the sleeve holes on the weighing module fixing seat through the first sleeve block and the second sleeve block, respectively, and are quickly fixed by bolts. This structure not only simplifies the installation process and reduces the installation difficulty, but also allows for the individual disassembly of faulty components during maintenance, avoiding damage to the overall structure.
