Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of enclosed water cooling system for distributor, effectively can intercept greasy dirt and gas dust to the pollution of water coolant, and can improve cooling performance.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of enclosed water cooling system for distributor, described distributor comprises distributor housing and distributor rotator, water-cooling system comprises and is arranged on rotator inlet flume outside distributor rotator and rotator effluent trough, rotator inlet flume and rotator effluent trough are separated by dividing plate, the lower end of rotator inlet flume is connected with water inlet thrust-augmenting nozzle, water coolant enters rotator inlet flume by the water inlet pipe being positioned at distributor case top, then the lower edge of distributor rotator is flow to along water inlet thrust-augmenting nozzle, each position that water coolant pours in distributor rotator cooling water channel from lower edge enters rotator return flume, the outside of described rotator effluent trough is also provided with stationary housing return flume, and described rotator effluent trough is provided with overflow weir near the side of stationary housing return flume.
In such scheme, described rotator effluent trough is provided with the first upflow tube and the second upflow tube that are positioned at different heights.
In such scheme, the bottom of described distributor housing is provided with stationary housing backwater cavity, and described stationary housing return flume is connected and fixed housing backwater cavity by pipe connecting, described stationary housing backwater cavity also with stationary housing next time water pipe be connected.
In such scheme, the top of described distributor housing is provided with stationary housing water pipe last time, is extracted out by the water coolant in stationary housing return flume by stationary housing water pipe last time.
In such scheme, the top of described rotator inlet flume is provided with water level gauge.
Implement the enclosed water cooling system for distributor of the present invention, there is following beneficial effect:
1, distributor rotator tank is divided into inlet flume and return flume by the present invention, is provided with some overflow weirs at the outer wall of return flume, is realized the flowing of water coolant by the difference of altitude controlling inlet flume liquid level and overflow weir, thus realizes the cooling to distributor;
2, the enclosed water cooling system of distributor of the present invention, effective isolation of water coolant and greasy dirt and gas dust can be realized, the liquid level difference controllable precise of water inlet and backwater, improve the recycle efficiency of water coolant, simultaneously because water coolant is each position that self-rotating body bottom freely pours in distributor rotator cooling water channel, can ensure to be full of water coolant completely in water channel, cooling performance also increases further.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the structural representation of the present invention for the enclosed water cooling system of distributor;
Fig. 2 is the structural representation of the present invention for another embodiment of enclosed water cooling system of distributor.
Embodiment
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As shown in Figure 1, the tank of distributor rotator 5 is divided into rotator inlet flume 2 and rotator return flume 3 by dividing plate for the enclosed water cooling system of distributor by the present invention.
First water coolant enters rotator inlet flume 2 by the water inlet pipe 1 being positioned at distributor housing 4 top, then flows to the lower edge of distributor rotator 5 along water inlet thrust-augmenting nozzle 6 always.The water outlet of existing common structure is cancelled in the bottom of distributor rotator 5, and changes into closed, and each position that therefore water coolant pours in distributor rotator 5 cooling water channel from lower edge finally enters rotator return flume 3.Some first upflow tubes 8 are provided with in a circumferential direction in the outer wall proper site of rotator return flume 3, overflowed by the first upflow tube 8 after water coolant enters rotator return flume 3, be provided with stationary housing return flume 7 in the below of the first upflow tube 8, stationary housing return flume 7 is fixed on distributor housing 4.Water coolant after spilling enters stationary housing return flume 7, some first metallic hoses are housed in the bottom of stationary housing return flume 7 and joint 10 is connected with the stationary housing backwater cavity 12 bottom distributor housing 4, water coolant flows into stationary housing backwater cavity 12 from stationary housing return flume 7, and the water coolant in stationary housing backwater cavity 12 flows out from some stationary housings next time water pipe 13 again.For preventing the flooding velocity of the first upflow tube 8 limited, the second upflow tube 9 is provided with above the first upflow tube 8, when the flooding velocity of amount of inlet water more than the first upflow tube 8, then carry out double-deck overflow, be also provided with the second metallic hose and joint 11 is communicated with stationary housing backwater cavity 12 at the sidewall proper height of stationary housing return flume 7 accordingly.Water level gauge 14 is provided with, for detecting the liquid level of rotator inlet flume 2 above rotator inlet flume 2.Rotator inlet flume 2 is determined with the liquid level difference H2 of stationary housing return flume 7, the number of upflow tube and the cooling power of diameter needed for distributor with the poor H1 of the liquid level of rotator return flume 3, rotator return flume 3.
Fig. 2 is another embodiment of the present invention.After water coolant enters stationary housing return flume 7, gravity is not relied on to flow out from distributor bottom, but above distributor housing 4, be provided with some stationary housing water pipes last time 15, by stationary housing water pipe last time 15, the water coolant in stationary housing return flume 7 is extracted out.
The enclosed water cooling system of this distributor, effective isolation of water coolant and greasy dirt and gas dust can be realized, the liquid level difference controllable precise of water inlet and backwater, improve the recycle efficiency of water coolant, simultaneously because water coolant is each position that self-rotating body bottom freely pours in distributor rotator cooling water channel, can ensure to be full of water coolant completely in water channel, cooling performance also increases further.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, also can make a lot of form, these all belong within protection of the present invention.
