Description
Technical Field
The utility model relates to a scraper blade film evaporator's scraper blade structure belongs to evaporation equipment technical field.
Background
The scraper film evaporator is also called a scraper film concentrator and is widely applied to the treatment process of chemical waste, a heating jacket is arranged in the shell of the scraper film evaporator, a rotatable scraper is arranged in the evaporator, feed liquid is added from the upper part of the evaporator along the tangential direction, the feed liquid is continuously scraped into a film on an evaporation surface through the rotary motion of the scraper, so as to achieve the effect of film evaporation, the scrapers used at present are generally a sliding scraper and a fixed scraper, wherein the sliding scraper is made of polytetrafluoroethylene, and the polytetrafluoroethylene scraper is easy to be quickly worn after the salt formed by the chemical waste in the evaporation crystallization of the scraper film evaporator is hardened, the fixed scrapers are made of metal materials, the length of each scraper is as long as that of the evaporation cylinder body, high machining and mounting accuracy is required, the connection strength is not high enough, and the replacement cost of the scrapers is also high.
Disclosure of Invention
The utility model aims to solve the technical problem that a scraper blade film evaporator's scraper blade structure is provided, the scraper blade has higher joint strength and lower replacement cost, can solve the not enough of prior art.
The technical scheme of the utility model is that: the utility model provides a scraper blade structure of scraper blade film evaporator, installs on scraper blade film evaporator's rotation axis, includes along the axial several scraper blade subassembly of installing on the rotation axis, the scraper blade subassembly is including installing last revolving rack and the lower revolving rack on the rotation axis, all be equipped with a plurality of scraper blades between last revolving rack and the lower revolving rack, the scraper blade bottom on the scraper blade subassembly of more top is not higher than the scraper blade top of adjacent scraper blade subassembly of less below. Each scraper blade has an upper connecting point and a lower connecting point which are connected with the upper rotating frame and the lower rotating frame, so that the connecting strength of the scraper blade is increased, the length of the scraper blade can be shorter, and the replacement cost is reduced.
Further the scraper blade inboard is provided with joint spare, go up the revolving rack and be provided with respectively with on the lower revolving rack with joint spare matched with draw-in groove. The scraper can be conveniently installed and detached on the upper rotating frame and the lower rotating frame.
And further, the clamping pieces on the scraping plates are matched with the clamping grooves and then fixed on the upper rotating frame and the lower rotating frame through the fasteners. The scraper blade is more firmly installed, and the scraper blade is prevented from falling off during rotating work.
And a plurality of scrapers on the plurality of scraper components are distributed in a staggered manner along the circumferential direction. The scrapers on the upper scraper component and the lower scraper component can not interfere with each other, and crystals on the evaporator cylinder body can be scraped fully.
Further, the scraper is made of hard metal materials. The scraper has better strength and prolonged service life.
To sum up, the utility model provides a scraper blade has higher joint strength and lower replacement cost, convenient change, to the abundant scraper blade film evaporator's of crystallization scraping on the evaporimeter stack shell scraper blade structure.

FIG. 2 is a schematic structural view of the present invention;
fig. 3 is a schematic view of the attachment of the screed to the turret.
Shown in the figure: a rotating shaft 1; an upper squeegee assembly 2; a lower squeegee assembly 3; a first upper turret 4; a first lower turret 5; a first squeegee 6; a second upper turret 7; a second lower turret 8; a second squeegee 9; a clip member 10; a card slot 11; a fastener 12; an evaporator shaft 13.
Detailed Description
The embodiment of the utility model provides a: as shown in fig. 1 to 3, a scraper structure of a scraper film evaporator is mounted on a rotating shaft 1 of the scraper film evaporator, and comprises two scraper assemblies which are mounted on the rotating shaft up and down along the shaft, the two scraper assemblies are an upper scraper assembly 2 and a lower scraper assembly 3 respectively, the upper scraper assembly 2 comprises a first upper rotating frame 4 and a first lower rotating frame 5 which are mounted on the rotating shaft 1, four first scrapers 6 are arranged between the first upper rotating frame 4 and the first lower rotating frame 5, the lower scraper assembly 3 comprises a second upper rotating frame 7 and a second lower rotating frame 8 which are mounted on the rotating shaft 1, four second scrapers 9 are arranged between the second upper rotating frame 7 and the second lower rotating frame 8, and the bottom of the first scraper 6 on the upper scraper assembly 2 is not higher than the top of the second scraper 9 of the lower scraper assembly 3. The upper and lower two connecting points of the first scraper 6, the first upper rotating frame 4 and the first lower rotating frame 5, and the upper and lower two connecting points of the second scraper 9, the second upper rotating frame 7 and the second lower rotating frame 8 increase the connecting strength, and the lengths of the first scraper 6 and the second scraper 9 can be shorter, so that the strength is further increased, and the replacement cost is reduced.
The first scraper 6 and the second scraper 9 of this preferred embodiment are provided with the joint 10 on the inboard, are provided with the draw-in groove 11 with joint 10 matched with on first upper rotating frame 4 and first lower rotating frame 5, second upper rotating frame 7 and the second lower rotating frame 8 respectively. The scraper can be conveniently installed and detached on the upper rotating frame and the lower rotating frame.
On the preferential joint spare 10 of first scraper blade 6 of this embodiment is fixed in first revolving rack 4 and first revolving rack 5 down through fastener 12 after with draw-in groove 11 cooperation, on revolving rack 7 and second revolving rack 8 are down fixed in to the second through fastener 12 after joint spare 10 of second scraper blade 9 and draw-in groove 11 cooperation, fastener 12 is matched with bolt and nut, the bolt passes to be connected with the nut behind revolving rack and the scraper blade, it is more firm to make the scraper blade installation, prevent that the scraper blade from dropping at rotatory during operation.
The four scrapers on the two scraper assemblies of the preferred embodiment are staggered along the circumferential direction. Make first scraper blade 6 and second scraper blade 9 on upper scraper blade subassembly 2 and the lower scraper blade subassembly 3 can not mutual interference, first scraper blade 6 bottom on the upper scraper blade subassembly 2 is less than the second scraper blade 9 top of lower scraper blade subassembly 3, and the scraper blade fully scrapes the crystallization on the evaporimeter stack shell 13.
The first blade 6 and the second blade 9 of the present embodiment are preferably made of a hard metal material. The scraper has better strength and prolonged service life.
