Abstract
The invention relates to a scraper type heat exchanger. The equipment mainly comprises a motor, a main shaft and a casing, wherein one or more grooves are formed on the inner wall of the casing; the main shaft is of a hollow tubular structure; when the main shaft is rotated under the driving of the motor, the grooves stir a feed liquid between the main shaft and the casing and scrape on a heat transfer surface of the main shaft, so that the heat transfer surface is cleared and the aims of quickly transferring heat and avoiding bad phenomena, such as generation of a coked film or crystallized feed liquid and the like on the heat transfer surface of the main shaft are fulfilled. The scraper type heat exchanger has the advantages of substituting the traditional scraper type heat exchanger, solving the problem of generation of the coked film or crystallized feed liquid and the like on the heat transfer surface of the heat exchanger and improving the quality of the feed liquid, along with simple operation and low cost.
Description
Technical field the present invention relates to a kind of heat exchanger that is used for the feed liquid heating, particularly a kind of scraped surface heat exchanger.
Background technology in the prior art, moment high temperature sterilization or the moment cooling processing in, the heat-transfer area of general heat exchanger easily generates coking film or feed liquid crystallization; A kind of scraped surface heat exchanger has been produced in the good food machinery equipment Co., Ltd design of overflowing in Zhaoqing, Guangdong, this equipment is mainly by motor, main shaft and heating muff are formed, between main shaft and heating muff, have and a plurality ofly be fixed on scraper plate on the main shaft by scraping panel seat, when main shaft rotates under driven by motor, scraper plate stirs feed liquid between main shaft and sleeve pipe, and on internal surface of sleeve pipe, scrape and clean heat-transfer area, this equipment has been avoided producing bad phenomenon such as coking film or feed liquid crystallization at the heat-transfer area of heat exchanger preferably, but this device structure complexity, the dead angle is more, not only be difficult to clean, and the cost of manufacture height.
Summary of the invention purpose of the present invention will overcome above-mentioned defective exactly, and a kind of new scraped surface heat exchanger is provided.
Technical scheme of the present invention is: a kind of scraped surface heat exchanger, this equipment is mainly by motor, main shaft and sleeve pipe are formed, one or more groove is arranged on the inwall of sleeve pipe, groove is thread groove or straight trough, the exterior angle of internal surface of sleeve pipe and groove is greater than 120 degree, main shaft is a hollow tubular structure, heat medium flows in main shaft, feed liquid flows between groove, when main shaft rotated under driven by motor, groove stirred feed liquid between main shaft and sleeve pipe, and scraped on the heat-transfer area of main shaft, and then the cleaning heat-transfer area, thereby reach flash heat transfer and the purpose of avoiding producing bad phenomenon such as coking film or feed liquid crystallization at the heat-transfer area of main shaft.
Advantage of the present invention and effect are: replaced scraped surface heat exchanger in the past, the heat-transfer area that has solved heat exchanger produces problems such as coking film or feed liquid crystallization.The present invention produces bad phenomenon such as coking film or feed liquid crystallization with the heat-transfer area that simple form solves heat exchanger, has improved the quality of feed liquid.The present invention is simple to operate, and cost is low.
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments for description of drawings.
The structure chart of Fig. 1 scraped surface heat exchanger of the present invention
The profile of Fig. 2 scraped surface heat exchanger of the present invention
The structure chart of the sleeve pipe of Fig. 3 scraped surface heat exchanger of the present invention
The cross-sectional view of the sleeve pipe of Fig. 4 scraped surface heat exchanger of the present invention
The specific embodiment such as Fig. 1,2,3,4 described be the structure of scraped surface heat exchanger of the present invention, this equipment mainly is made up of motor 1, main shaft 2 and sleeve pipe 3, one or more groove 4 is arranged on the inwall of sleeve pipe 3, groove 4 is thread groove or straight trough, main shaft 2 is a hollow tubular structure, and the exterior angle 8 of sleeve pipe 3 inwalls and groove 4 is greater than 120 degree.Material flows from material import and export 5 turnover and 4 of grooves, heat medium is imported and exported 6 turnover and mobile main shaft 2 from medium, heat medium heats by 7 pairs of materials of heat-transfer area, when main shaft 2 rotates under motor 1 drives, groove 4 stirs feed liquid between main shaft 2 and sleeve pipe 3, and on the heat-transfer area 7 of main shaft 2, scrape, and then cleaning heat-transfer area 7, thereby reach flash heat transfer and the purpose of avoiding on heat-transfer area 7, producing bad phenomenon such as coking film or feed liquid crystallization.
