Description

Technical Field

[0001] The utility model relates to the technical field of production filtration equipment, in particular to a febuxostat production filtration equipment. Background Art

[0002] Febuxostat is a drug used to treat gout and hyperuricemia. It reduces the synthesis of uric acid by inhibiting the activity of xanthine oxidase. In the production process of febuxostat, filtration equipment is needed to filter the stock solution.

[0003] Most of the current production filtration equipment uses filters and the like for filtration. During the use of the filter, debris will accumulate on the filter, making it difficult for the stock solution to pass through. Cleaning the filter often requires disassembling the filter after stopping production, which will cause a decrease in production speed.

[0004] Therefore, aiming at the situation that the existing production filtration equipment needs to disassemble the filter for cleaning, a self-cleaning production filtration equipment can be designed to automatically clean the filter during production, ensure the filtration speed, and enhance the practical value of the device. Summary of the Utility Model

[0005] In order to overcome the problem that most production filtration equipment uses filters and the like for filtration. During the use of the filter, debris will accumulate on the filter, making it difficult for the stock solution to pass through. Cleaning the filter often requires disassembling the filter after stopping production, which will cause a decrease in production speed.

[0006] The technical solution of the utility model is: a febuxostat production filtration equipment, including a base, a bin assembly, a filtration assembly, a scraper, a power rod, a motor, a collection assembly and a discharge assembly; a bin assembly is arranged above the base, a filtration assembly is arranged inside the bin assembly, a scraper is arranged above the filtration assembly, a power rod is arranged above the scraper, a motor is arranged at one end of the power rod, a collection assembly is arranged on one side of the bin assembly, and a discharge assembly is arranged at the bottom of the bin assembly.

[0007] Preferably, by setting a base support device, the bin assembly is used to hold the stock solution to be filtered, and the filtration assembly is used to filter the stock solution. During the filtration process, the motor drives the power rod to drive the scraper to scrape off the debris accumulated on the filtration assembly, and the debris is collected by the collection assembly. Finally, the discharge assembly facilitates the discharge of the filtered stock solution.

[0008] As a preference, the bin assembly includes a filtration bin, a feed inlet and a slag discharge baffle; the filtration bin is arranged above the base, the feed inlet is arranged on one side of the filtration bin, and the slag discharge baffle is arranged on one side of the filtration bin; the raw material is injected into the filtration bin through the feed inlet for filtration, and the slag discharge baffle is used to prevent the slag generated by filtration from moving out of the device range.

[0009] Preferably, the filtering component includes a filter screen plate, a sliding seat and a handle; a sliding seat is arranged inside the filtering bin, a filter screen plate is arranged inside the sliding seat, and a handle is arranged on one side of the sliding seat; the raw liquid is filtered by the filter screen plate, and the sliding seat can be pulled out through the handle for overhaul and replacement of the filter screen plate during maintenance.

[0010] Preferably, the collecting component includes a collecting box, a filtering cage and a reflux pipe; a collecting box is arranged on one side of the filtering bin, a filtering cage is arranged inside the collecting box, and a reflux pipe is arranged at the bottom of the collecting box; the discharged dregs are collected by the collecting box, the raw liquid discharged together with the dregs is secondarily filtered by the filtering cage, and the filtered raw liquid flows into the bottom of the filtering bin through the reflux pipe.

[0011] Preferably, the discharging component includes a discharging pipe and a valve; a discharging pipe is arranged at the bottom of the filtering bin, and a valve is arranged above the discharging pipe; the filtered raw liquid is discharged through the discharging pipe, and the flow state of the discharging pipe is controlled by the valve.

[0012] Preferably, the range of rotation of the scraper can cover the filter screen plate, the power rod is located on the rotation axis of the scraper, and the power rod is connected to the output end of the motor; the motor drives the power rod to drive the scraper to rotate, scrape up the dregs accumulated on the filter screen plate, and send them into the collecting box.

[0013] Preferably, the sliding seat is slidably connected to the filtering bin. When the sliding seat is inside the filtering bin, the sliding-out side of the sliding seat is in a sealed state with the filtering bin; it is ensured that during the use of the device, the raw liquid will not flow out from the sliding gap between the sliding seat and the filtering bin.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. Compared with most traditional production filtering devices that use filter screens for filtering, during the use of the filter screen, sundries will accumulate on the filter screen, making it difficult for the raw liquid to pass through. Cleaning the filter screen often requires disassembling the filter screen after stopping production, which will cause a decrease in production speed. By adding a self-cleaning structure, this device can automatically clean the filter screen during production, ensure the filtering speed, collect the dregs generated during cleaning, ensure the cleanliness of the production environment, recycle the production raw liquid contained in the dregs at the same time, reduce waste in production, and perform secondary filtering during the recycling process to ensure the filtering effect and enhance the practical value of the device;

[0016] 2. During cleaning, power is generated by the motor to rotate the power rod, thereby driving the scraper to rotate, scraping up the residues accumulated on the filter screen plate, and continuously moving under the drive of the scraper. Blocked by the slag discharge baffle, the residues fall into the collection box, and the filter cage performs secondary filtration on the residues, allowing the original liquid in the residues to flow out of the filter cage and flow into the bottom of the filtration chamber through the return pipe, so as to solve the problem that most production filtration equipment mostly uses filter screens for filtration. During the use of the filter screen, sundries will accumulate on the filter screen, making it difficult for the original liquid to pass through. Cleaning the filter screen often requires disassembling the filter screen for cleaning after stopping production, which will cause a decrease in production speed;

[0017] 3. When the equipment is in use, the original liquid to be filtered is injected into the filtration chamber from the feed port. When passing through the filter screen plate, the original liquid is filtered, and the residues are blocked and left behind. The original liquid enters the bottom of the filtration chamber and can flow out of the filtration chamber through the discharge pipe for use. The rotary valve can control the flow state of the discharge pipe. When the equipment stops production, the sliding seat can be pulled out by the handle, and the filter screen plate can be pulled out of the filtration chamber for maintenance and replacement.
