Description

Technical Field

[0001] This utility model relates to the field of pyrazol hydrochloride production technology, and in particular to a vertical composite filter for pyrazol hydrochloride production. Background Technology

[0002] Pyrazol hydrochloride is an organic compound formed by the reaction of pyrazol and hydrochloric acid. In the pharmaceutical field, it is often used as a drug intermediate to improve drug stability and solubility, enhance efficacy and bioavailability. In the chemical industry, it can also be used to synthesize functional materials or participate in organic synthesis. Vertical composite filters are used in the production of pyrazol hydrochloride because they are highly efficient, capable of processing large quantities of material and precisely removing impurities, thus improving product purity; they are easy to operate, automating multiple processes, reducing labor intensity and stabilizing product quality; they are highly adaptable, allowing for flexible parameter adjustments based on different processes and material characteristics; they save space, with a small footprint due to their vertical structure, facilitating integration with other equipment and optimizing the production process; and they are environmentally friendly and energy-saving, recovering useful components from the filtrate, reducing material loss and waste emissions.

[0003] Currently, most vertical composite filters on the market rely solely on a single stirring structure to agitate raw materials during operation, hoping to achieve uniform filtration. However, these filters generally suffer from a serious drawback: the lack of a necessary cleaning structure. During continuous production, some raw materials inevitably remain inside the machine, making complete filtration difficult. Over time, these residual materials gradually corrode the internal components, leading to increasingly severe corrosion and ultimately significantly shortening the overall lifespan of the equipment. This severely impacts the continuity and stability of production. Therefore, a vertical composite filter for pyrazolium hydrochloride production is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a vertical composite filter for the production of pyrazolium hydrochloride, which aims to improve the problem that most vertical composite filters rely on a single stirring structure for uniform filtration. Due to the lack of a cleaning structure, raw material residue can lead to machine corrosion, thereby shortening the machine's service life.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vertical composite filter for the production of pyrazolium hydrochloride, comprising a housing, a top cover provided on the upper surface of the housing, bolts running through the housing and the top cover, a reducer fixedly connected to the upper surface of the top cover, a rotating shaft fixedly connected to the output end of the reducer, and a cleaning component installed on the outer wall of the rotating shaft;

[0006] The cleaning assembly includes a connecting rod, one end of which is fixedly connected to one side of the outer wall of the rotating shaft, and the other end of which is fixedly connected to a spring. One end of the spring is fixedly connected to a scraper, and one side of the outer wall of the scraper is fixedly connected to a sleeve. The inner wall of the sleeve is slidably connected to the outer wall of the connecting rod. A second scraper is fixedly connected to the lower side of the outer wall of the rotating shaft. A scraping assembly is installed on the inner wall of the housing, and a feed hopper is fixedly connected to the upper surface of the top cover.

[0007] Furthermore, the scraping component includes a positioning block, one side of the outer wall of the positioning block is fixedly connected to one side of the inner wall of the housing, a filter plate is slidably connected to the upper surface of the positioning block, an installation cylinder is rotatably connected inside the filter plate, an installation rod is fixedly connected to the lower surface of the installation cylinder, a scraper plate is fixedly connected to the lower surface of the installation rod, and a cross-shaped locking block is fixedly connected to the lower surface of the rotating shaft, with the outer wall of the cross-shaped locking block slidably connected inside the installation cylinder.

[0008] Furthermore, a filter box is provided on one side of the housing, and a filter cartridge is slidably connected inside the filter box.

[0009] Furthermore, a connecting pipe is fixedly connected to the lower surface of the housing, a water pump is installed on one side of the filter box, the input end of the water pump is fixedly connected to one end of the connecting pipe, and the output end of the water pump is fixedly connected to a connecting pipe.

[0010] Furthermore, one end of the connecting pipe is fixedly connected to the upper surface of the filter box, and an air outlet pipe is fixedly connected to the upper surface of the filter box.

[0011] Furthermore, a fan is fixedly connected to the upper surface of the filter box, a transmission pipe is fixedly connected to the input end of the fan, and a transmission pipe is fixedly connected to the output end of the fan.

[0012] Furthermore, one end of the transmission pipe is fixedly connected to the inside of the top cover, and one end of the transmission pipe is fixedly connected to the lower side of the inside of the filter box.

[0013] Furthermore, a water outlet pipe is fixedly connected to one side of the outer wall of the filter box, and the water outlet pipe is used to transport liquid.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the connecting rod on the outer wall of the rotating shaft is driven to rotate by the reducer. At this time, the extension and contraction of the spring is used to drive the scraper to achieve the effect of scraping and cleaning. Then, the cross-shaped locking block drives the scraper below the mounting rod to clean the waste liquid simultaneously. At the same time, by removing the bolts and opening the top cover, the cross-shaped locking block is disengaged from the inside of the mounting cylinder. Then, by removing the filter plate from the upper surface of the positioning block, the scraper is disengaged from the inside of the machine. This makes it easier to clean the inside of the machine, thereby improving the practicality of the machine.

[0016] 2. In this utility model, the waste liquid inside the housing is transferred to the inside of the second connecting pipe through the first connecting pipe by the water pump, thereby achieving the effect of transferring the waste liquid to the inside of the filter box for filtration. Then, the filtered waste liquid is discharged through the outlet pipe. The exhaust gas inside the housing is then transferred to the inside of the filter box through the first and second connecting pipes by the fan, thereby achieving the effect of using waste liquid to adsorb harmful gases for filtration, thus improving the practicality of the machine.

[0029] Working Principle: When using this vertical composite filter, the raw material is first transferred to the inside of the housing 1 through the feed hopper 27. Then, the reducer 4 is started, which drives the connecting rod 6 on the outer wall of the rotating shaft 5 to rotate. This causes the scraper 8 to scrape against the inner wall of the housing 1. The extension and retraction of the spring 7 then achieves the effect of cleaning the raw material on the inner wall of the housing 1 while reducing the scraping pressure. At this time, the cross-shaped locking block 11 drives the mounting rod 14 below the mounting cylinder 12 to rotate, and the mounting rod 14 drives the scraper 15 to scrape against the waste liquid. When it is necessary to clean the internal structure of the machine, the bolt 3 is unscrewed, and the cross-shaped locking block 11 is then disengaged from the mounting cylinder 12. Then, by removing the filter plate 13 from inside the housing 1, the movement of the filter plate 13 achieves the effect of removing the scraper plate 15 from the housing 1 for disassembly and cleaning. At this time, by starting the water pump 19, the waste liquid is transferred from inside the housing 1 to the filter box 17 through the connecting pipe 18 and the connecting pipe 20. The waste liquid is then filtered through the filter box 21. At the same time, by starting the fan 23, the harmful gas inside the housing 1 is transferred through the connecting pipe 24 and the connecting pipe 25 to the liquid inside the filter box 17 for adsorption. At this time, the clean gas is discharged from the filter box 17 through the air outlet pipe 22, and the filtered waste liquid is discharged through the water outlet pipe 26.
