Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of centrifugal equipment, and particularly relates to a centrifugal equipment for particulate matter production with rapid material discharge. Background Art
[0002] Polyarylate is a high-performance polymer belonging to the category of aromatic polyesters. They are mainly formed by the polymerization reaction of aromatic diacids and aromatic alcohols. Polyarylate has some unique physical and chemical properties, making it widely used in industry and technology. The production of polyarylate usually involves a polycondensation reaction of aromatic diacids and aromatic alcohols, and the synthesized polyarylate is a suspension crystal liquid with a separating agent as a solvent. Currently, polyarylate crystal particles are obtained by the direct evaporation method. However, the particles obtained by this method will contain a large amount of impurities, including sodium chloride impurities and raw material impurities, making the subsequent purification process difficult.
[0003] Among many existing technologies, Chinese Patent Application CN116474947A discloses a plate centrifuge and its use method, belonging to the technical field of plate centrifuges. A plate centrifuge includes a base; an outer cylinder, a cover plate lifting and flipping assembly, and a centrifugal assembly are installed on the top of the base. The centrifugal assembly is used for centrifugal driving; the cover plate lifting and flipping assembly includes a vertical driving assembly, an azimuth adjustment assembly, and a cover plate. The cover plate is connected with a chopping assembly and a material distributing assembly. The spraying end position of the material distributing assembly is inside the centrifugal assembly, and the material distributing assembly is used for evenly spraying materials inside the centrifugal assembly; the chopping assembly includes a first transverse driving assembly and a cutter assembly. The first transverse driving assembly is connected with the cover plate, and the first transverse driving assembly is connected with the cutter assembly.
[0004] However, the drum of this patent application is an integrated structure drum. During maintenance, usually the entire component needs to be replaced, rather than just the damaged part, which may lead to higher maintenance costs and downtime. At the same time, using pulsed air or high-pressure water source to enter the blockage clearing assembly and spray out from the nozzle towards the drum will cause the solid-liquid mixture washed down to flow into the discharge channel, contaminating the processed materials. If pollution is to be avoided, only the current material collection bin can be removed and replaced with a collection bin to collect the solid-liquid mixture washed down, and the steps are cumbersome and not easy to operate.

Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0032] The "left", "right", "front", "rear", "upper" and "lower" mentioned in the following description are oriented in the perspective direction of the front view.
[0033] Embodiment 1: In some embodiments, please refer to the Figures 1-6 drawings of the specification. A centrifugal device for particulate production with rapid material discharge includes a mounting plate 1, on which a housing assembly 2 is mounted. Inside the housing assembly 2, a centrifugal assembly 3 that can be partially replaced is provided. The centrifugal assembly 3 is connected to the mounting plate 1. A spraying pipe 4 for spraying a suspension crystal solution of polyarylate and a cleaning pipe 5 for cleaning and unblocking the centrifugal assembly 3 are mounted on the housing assembly 2. A scraping assembly 6 for scraping polyarylate crystals is mounted on the housing assembly 2. A drain pipe 8 for draining water is fixedly mounted on the mounting plate 1;
[0034] It further includes a feeding switching assembly 7 for switching polyarylate crystals and cleaning liquid to different feeding channels. The feeding switching assembly 7 is connected to the centrifugal assembly 3;
[0035] The blanking switching component 7 includes a three-way pipe 71, a servo motor 72, a baffle 73, a base 74, and a rotating shaft 75.

[0036] When the present utility model is in use, the suspension crystallization liquid of polyarylate is injected from the spraying pipe 4 and sprayed on the centrifugal component 3. The centrifugal component 3 performs centrifugal treatment on the suspension crystallization liquid of polyarylate. When a certain amount of the suspension crystallization liquid of polyarylate is injected, the spraying pipe 4 stops spraying the suspension crystallization liquid of polyarylate. After separating the polyarylate crystals from the separating agent, the scraping component 6 scrapes off the polyarylate crystals attached inside the centrifugal component 3 and discharges them through one side channel of the three-way pipe 71.

At this time, the servo motor 72 drives the rotating shaft 75 to drive the baffle 73 to make the baffle 73 fit against the opposite side wall, realizing the switching of the channel, so that the washed solid-liquid mixture flows into the other side channel of the three-way pipe 71, and then is collected and centrifuged again, avoiding the blockage of the holes on the centrifugal component 3 and also avoiding material waste, while the flushing water on the outside is discharged from the drain pipe 8.
