Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the present invention will be described:
The utility model structure as shown in Figure 1, 2, comprises forward flange dish 1, rear stub 2, front reducing housing 3, rear reducing housing 4, and energy sheet 5 is unloaded in front filtration, and rear filtration cut out tab 6, is connected and fixed bar assembly 7, forms silk 8 and blowoff valve 9; Wherein, ring flange 1,2 welds with the both sides port of reducing housing 3,4 respectively, filtration unload can sheet 5 with filter cut out tab 6 be arranged on fixed connecting rod assembly 7 forms filtration unloads can assembly, this filtration is unloaded and can is arranged in the space, large footpath of long front reducing housing 3 by component integration, as shown in Figure 3, the bigger diameter end subordinate side of long reducing housing 3 has sewage draining exit, front reducing housing 3 is docked by flange with the bigger diameter end mouth of rear reducing housing 4, bolted, for convenience detach, blowoff valve 9 and reducing housing 3 are by being connected to the sewage draining exit place on the downside of reducing housing 3 end to silk 8.
The utility model is arranged on the water inlet port of heat exchanger unit, to after using single hydrocyclone, also can there is the further filtration of the tiny grains of sand problem of part in water quality, and can effectively reduce current and affect for the impact of heat exchanger internal heat exchange tubes.
Each parts specific embodiment in present device is respectively described below:
Ring flange 1, ring flange 2, and the mounting flange between two reducing housings is conventional specification product.Can select according to heat exchanger mouth of a river caliber adjustment coupling.
Front its miner diameter end of reducing housing 3 is according to heat exchanger water inlet match of pipe diameter, bigger diameter end caliber is according to the optional different tube diameters specification of concrete actual conditions, generally be not less than 1.5 times of path, the overall length dimension of reducing housing also can adjust according to actual requirement (being not less than 3 times of minor diameter), can better improve the effect of unloading and can remove sand.
The large footpath of rear reducing housing 4 and path and front reducing housing 3 measure-alike, its length is not less than 2 times of path.
This removes sand and unloads 5 times that energy device total length is path.
Filtration unloads energy sheet 5 for a circular filter mesh sheet is as shown in Fig. 3 (a), diameter is identical with the large footpath of reducing housing 3, it cuts a small gap (cut height is 1/10th of filter net sheet diameter) below, filtering cut out tab 6 is that a circular filter mesh sheet is as Fig. 3 (b), it is imperforate baffle below, imperforate baffle size and filtration unload can sheet 5 to cut small gap measure-alike, the dirt being deposited on bottom in front reducing housing 3 shell is blocked in its effect, and dirt is discharged from sewage draining exit.
Filtration is unloaded and can be filter net sheet with filtration cut out tab 6 by sheet 5, front filtration is unloaded and the screen distance of sheet can be greater than the screen distance of rear filtration cut out tab, different material specifications and filter screen order number can be selected according to the actual water quality in scene, between the two apart from being not less than 2 times of little electrical path length, the filtration of its deuterzooid structure is unloaded and the quantity of sheet also can be not limited to and select two, specifically can adjust according to actual field situation and select.
The conventional products matched all is selected to silk 8 and blowoff valve 9.
Embodiment:
The heat exchanger water inlet pipe latus rectum 100mm of application the present embodiment, ring flange 1,2 matches and selects, long front reducing housing 3 path latus rectum is 100mm, large footpath latus rectum is 150mm, reducing housing 3 total length is 300mm, the large footpath of short rear reducing housing 4 and path and reducing housing 3 measure-alike, reducing housing 4 total lengths >=200mm, it can sheet 5 external diameter be 100mm that filtration is unloaded, lower end cut height is positioned at 10mm place, filtration is unloaded and can be also positioned at 10mm place by sheet 6 imperforate baffle height, filters the spacing of unloading between energy sheet 5,6 and answers >=200mm.
This removes sand and unloads can device total length be 500mm.
The course of work of this heat exchanger is: during operation, when water route in pipe is along A to when entering in reducing housing 3, inner side caliber becomes large, water route flow velocity reduces, unload can manage interior water route flow velocity by further reduction of sheet 5 and 6 by filtering, wherein filter the pore size filter unloaded on energy sheet 6 and be less than the aperture of filtering and unloading energy sheet 5, in order to reach the effect of filtering more fine impurity.In the process by the change of caliber with filter that unload can the deceleration of sheet, grains of sand impurity in water quality precipitates, under the percussion of current, sediment is through filtering the otch 10 (as shown in Figure 4) unloading energy B place, sheet 5 lower end, then through filtering the imperforate baffle unloading energy sheet 6 lower end 11 place, lodged contamination is made not unload energy sheet 6 by filtering, and enable lodged contamination form deposition shape 12 at sewage draining exit place, reducing housing 3 lower end, as Fig. 4 (b), in the process that unit uses, only need regularly open blowoff valve 9, deposit is discharged.
Secondly the utility model structure, filters and unloads and can realize dismounting by sheet, facilitate self-filtering to unload the cleaning of energy sheet.During installation, this utility model structure should be arranged near heat exchanger water inlet as far as possible, thus is unloading the impact failure effectively protecting heat exchanger internal heat exchange tubes in energy process.
