Abstract
The utility model discloses a scraper blade for a heat exchanger, which comprises a cylindrical and hollow shell, wherein the outer wall of the shell is fixedly connected with a plurality of mounting blocks, and each three mounting blocks are connected with a scraper blade; one side integrated into one piece of scraper has three connection piece, be equipped with the rectangular hole on every connection piece, every installation piece top is equipped with the breach, be equipped with the jack that link up on every installation piece, the breach divide into lug one and lug two with the upper end of installation piece, lug one inserts in the rectangular hole, make the connection piece by the breach embedding jack in and rather than rotatable coupling, the top of lug one is equipped with the screw, the top of lug two articulates there is the fixed plate, be equipped with on the fixed plate with screw complex round hole, the fixed plate passes through the screw connection with the installation piece. The scraper is detachably connected with the shell, so that the scraper is easy to replace and low in maintenance cost; when the shell rotates, the scraper rotates at a certain angle along the mounting block, the tail end of the scraper inclines towards the inner wall of the material barrel, and a coking film or feed liquid crystal can be effectively scraped.
Description
Technical Field
The utility model relates to a heat exchanger technical field specifically is a scraper blade for heat exchanger.
Background
The scraper type heat exchanger is a heat exchanger which stirs feed liquid by means of scrapers and cleans a heat transfer surface to accelerate heat transfer efficiency, and is not only suitable for low-viscosity feed liquid, but also especially suitable for rapid heat exchange of high-viscosity or particle-containing feed liquid. Scrapers are important components in scraped surface heat exchangers, and the disadvantages of the prior scrapers are: (1) the scraper is fixedly arranged on the shell and cannot deviate along with the rotation of the shell, so that the coking film attached to the inner wall of the material barrel cannot be scraped in time; (2) because the scraper is fixedly arranged on the shell, the scraper is easy to wear after being used for a long time, and the scraper cannot be replaced after being damaged, so that the maintenance cost is high.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a scraper blade for heat exchanger to the weak point of prior art, in order to solve above-mentioned problem.
In order to achieve the above object, the utility model provides a following technical scheme:
a scraper for a heat exchanger comprises a cylindrical hollow shell, wherein the outer wall of the shell is fixedly connected with a plurality of mounting blocks, and every three mounting blocks are connected with a scraper; one side integrated into one piece of scraper has three connection piece, is equipped with the rectangular hole on every connection piece, and every installation piece top is equipped with the breach, is equipped with the jack that link up on every installation piece, breach and jack intercommunication, the breach divide into lug one and lug two with the upper end of installation piece, lug one inserts in the rectangular hole, makes the connection piece imbed in the jack and rather than rotatable coupling by the breach, the top of lug one is equipped with the screw, the top of lug two articulates there is the fixed plate, be equipped with on the fixed plate with screw complex round hole, the fixed plate passes through bolted connection with the installation piece.
The utility model has the advantages that:
(1) the scraper can be dismantled with the casing and be connected, and when the scraper wearing and tearing back, quick detachable and change, cost of maintenance is low.
(2) When the casing rotates, because the effect of centrifugal force makes the scraper carry out certain angle's rotation along the installation piece, makes the end of scraper incline to material barrel inner wall, can effectually strike off coking film or feed liquid crystallization, further guarantees the quality and the health of feed liquid.

FIG. 2 is an enlarged view of a portion of FIG. 1 at A;
in the figure, 1-shell, 2-mounting block, 3-scraper, 4-connecting sheet, 5-rectangular hole, 6-notch, 7-jack, 8-first lug, 9-second lug, 10-fixing plate and 11-screw.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.
Referring to fig. 1-2, a scraper for a heat exchanger includes a cylindrical and hollow casing 1, wherein the outer wall of the casing 1 is fixedly connected with a plurality of mounting blocks 2, and every three mounting blocks 2 are connected with a scraper 3; one side integrated into one piece of scraper 3 has three connection piece 4, be equipped with rectangular hole 5 on every connection piece 4, 2 tops of every installation piece are equipped with breach 6, be equipped with the jack 7 that link up on every installation piece 2, breach 6 and jack intercommunication, breach 6 is divided into lug one 8 and lug two 9 with the upper end of installation piece 2, lug one 8 inserts in the rectangular hole 5, make connection piece 4 by in breach embedding jack 7 and rather than rotatable coupling, the top of lug one 8 is equipped with the screw, the top of lug two 9 articulates there is fixed plate 10, be equipped with on the fixed plate 10 with screw complex round hole, fixed plate 10 passes through screw 11 with installation piece 2 and is connected.
The utility model discloses be applied to in scraping plate heat exchanger, scrape plate heat exchanger and include main shaft, material cylinder, the scraper blade be located the main shaft periphery, material cylinder is located the scraper blade periphery, when the main shaft drives the casing 1 of scraper blade and rotates, because the effect of centrifugal force makes scraper 3 along carrying out the upset of certain angle with installation piece 2, makes scraper 3's end to material cylinder inner wall slope, can effectually strike off adhesion at the coking film or the feed liquid crystallization of material cylinder inner wall, further guarantees the quality and the health of feed liquid. When the scraper 3 is worn, the scraper 3 can be taken down only by loosening the screw 11 and pulling the fixing plate 10 open, so that the scraper is easy to disassemble and replace, and the maintenance cost is low.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
