Description

Technical Field

[0001] The utility model relates to the technical field of lightweight plastering gypsum production, in particular to a lightweight plastering gypsum production filtering device. Background Art

[0002] Lightweight plaster gypsum is a mortar made from building gypsum powder, vitrified microspheres or high-strength expanded perlite particles as the main raw materials, with other auxiliary materials and admixtures added. Its density is lighter than that of ordinary gypsum mortar, so it is called lightweight gypsum mortar or expanded perlite mortar. This material is lightweight, fireproof, moisture-proof, easy to process and simple to install. It is particularly suitable for leveling and insulation of interior walls and floor slabs in dry areas. In the production process of lightweight plaster gypsum, the uniformity and fineness of the raw materials are crucial to the quality of the final product, so a filtering device is required to ensure the purity and uniformity of the raw materials.

[0003] The existing Chinese patent with announcement number CN218393850U discloses a lightweight plaster gypsum production filtering device, including a filter bin, filter screens are fixedly connected to both sides of the top of the filter bin, two groups of filter screens are fixedly connected to the bottom of the side close to each other with a crushing mechanism, a swing mechanism is fixedly connected at the middle position of both sides of the filter bin, mounting plates are fixedly connected to both sides of the two ends of the filter bin, the bottoms of the two groups of mounting plates are rotatably connected to a rotating shaft, and a second gear is fixedly connected to the outer side of the rotating shaft.

[0004] Although the above scheme does not need to collect and crush the agglomerated plaster gypsum again, thus reducing the workload, the overall structure of the filtering device is relatively fixed, and more complex materials need to be disassembled for internal cleaning, which makes it inconvenient to clean the internal filter frame. At the same time, the filtering device lacks the function of collecting and reminding, which requires the operator to check the capacity status of the filtering device when performing filtering operations. This not only increases the burden of manual monitoring, but also easily distracts the operator from the filtration process itself, affecting work efficiency. Therefore, it does not meet existing needs. In this regard, we propose a lightweight plaster gypsum production filtering device. Utility Model Content

[0005] The purpose of the utility model is to provide a lightweight plaster gypsum production filtering device to solve the problems proposed in the above background technology that the overall structure of the filtering device is relatively fixed, affecting internal cleaning and lacks a collection reminder function, resulting in direct labor burden and affecting production efficiency.

The lower end of the pull rod 6 is adhered and fixed with a pressing plate 8, and the pressing plate 8 is in contact with the fixing frame 5.

[0031] It also includes a dust box 17, which is arranged on both sides of the upper end of the upper body 2. Four equally spaced dust screens 18 are provided inside the dust box 17. Dust covers 20 are provided on both sides of the upper end of the filter cavity 4. The dust covers 20 are connected to the dust box 17 by connecting pipes.

[0032] It also includes a weighing sensor 14 , which is arranged at the lower end of the filter cavity 4 . A collection box 13 is provided at the upper end of the weighing sensor 14 , and the collection box 13 is fitted to the weighing sensor 14 .

[0033] During use, raw materials are added into the filter chamber 4 through the feed pipe 3, and the filter plate 10 filters the raw materials. The filter plate 10 can be easily replaced and cleaned through the linkage of the pulling plate 9, the pull rod 6 and the return spring 7. The suction machine 19 cooperates with the dust collecting hood 20 to effectively collect the dust generated during filtration into the dust collecting box 17. The dustproof net 18 intercepts the dust. The weighing sensor 14 monitors the weight of the collection box 13 in real time, and compares it with the preset standard value through the PLC controller 15. When the standard is reached, the alarm 16 is triggered to prompt the staff to take out the raw materials through the first sealing door 21, which reduces the burden on the operator, improves production safety and stability, and avoids dust pollution and overfilling and overflow problems.

[0040] Working principle: When in use, the raw materials for the production of lightweight plaster gypsum are added to the interior of the filter chamber 4 through the feed pipe 3, and the raw materials can be filtered through the filter plate 10 to ensure the quality of subsequent production. By starting the electric telescopic rod 23, the upper main body 2 can be moved upward, and the rectangular protrusion 11 will separate from the rectangular groove 12, thereby completing the separation of the upper main body 2 and the lower main body 1, and the operator can easily clean the interior. When cleaning, the connecting plate 9 can be pulled, and the connecting plate 9 will drive the pull rod 6 to move upward, and the pull rod 6 will drive the pressure plate 8 to move upward. The upward movement of the pressure plate 8 will compress the return spring 7, thereby releasing the clamping fixation of the filter plate 10, and then the filter plate 10 can be easily taken out for cleaning, making cleaning more convenient. When filtering the raw materials, dust is easily generated inside. At this time, the suction machine 19 can be started, and the suction machine 19 will extract the air in the dust box 17 to make the interior negative pressure. The dust hood 20 can be sucked by connecting the connecting pipe. The force can suck the scattered dust into the interior of the dust collecting box 17, and the inhaled dust can be intercepted by the dustproof net 18. The operator can clean the internal dust by opening the second sealing door 22, avoiding dust pollution to the working environment. The qualified raw materials will fall into the interior of the collection box 13, and the weighing sensor 14 will weigh the weight of the collection box 13 and send the weighing data to the PLC controller 15 through an electrical signal. The operator can set the standard value in the interior of the PLC controller 15 in advance. When the standard value is reached, the PLC controller 15 will start the alarm 16, and the alarm 16 will sound an alarm to attract the staff. The collection box 13 can be taken out by opening the first sealing door 21 to discharge the raw materials, so that the operator's force can be concentrated on filtering, which reduces the burden on the operator and avoids the problem of overfilling and overflowing due to human negligence, thereby improving the stability and safety of the production process.
