Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings in which the embodiments are described below. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

Referring to fig. 1-5, the automatic blowdown device for the steam drum comprises a tank body 1, wherein a water inlet 2 is formed in the upper end of the tank body 1, a water outlet 3 is formed in the lower end of the tank body 1, electromagnetic valves are arranged in the water inlet 2 and the water outlet 3 of the tank body 1, a controller 4 is arranged at the lower end of the tank body 1, the two electromagnetic valves are electrically connected with the controller 4, and a filtering assembly 5 is arranged at the upper end of an inner cavity of the tank body 1.

Further, consider that some solid impurity that are not dissolved by it contains in the drum sewage, and when discharging drum sewage, solid impurity also can be discharged along with sewage, so can lead to the condition of blockking up by solid impurity in the pipeline to appear, so set up filter assembly 5 and solve this problem, filter assembly 5 includes filter screen 6, ring baffle 7 and scraper blade 8, ring baffle 7 is located the first half of jar body 1 inner chamber, and ring baffle 7 and jar body 1's inner chamber fixed connection, the middle part of ring baffle 7 is equipped with rather than the filter screen 6 of rotation connection, because drum sewage filters the discharge through filter screen 6, and filter screen 6 probably appears by solid impurity blocking's phenomenon, influence the speed of sewage discharge, so be equipped with the scraper blade 8 with the laminating of filter screen 6 in ring baffle 7's inboard, the upper end of filter screen 6 is equipped with drive filter screen 6 pivoted drive assembly 9, drum sewage enters into jar body 1 through water inlet 2 in, filter through filter screen 6, solid impurity after filtering, just fall on ring baffle 7.

Furthermore, filter screen 6 is the semicircle setting, and the solid impurity of being convenient for rolls on falling ring baffle 7, avoids solid impurity to pile up on filter screen 6, and influences sewage discharge's speed.

Further, consider that after the steam pocket sewage discharges for a long time, some solid impurity will be piled up on the ring baffle 7, so need clear up it, so the 1 both sides of the jar body of 7 upper end positions of ring baffle are equipped with recess 10, and be equipped with in the recess 10 rather than complex arc piece 11, the ring baffle 7 that is close to arc piece 11 one side sets up for the downward sloping, be convenient for after opening arc piece 11, the solid impurity on the ring baffle 7 can roll out, be convenient for clear up it, and two arc pieces 11 fix through bolt 12, through rotating out bolt 12, open and jar body 1 articulated arc piece 11, roll out thereupon through the solid impurity on the ring dog.

Further, consider that the solid impurity of being filtered out by filter screen 6 may block on filter screen 6, lead to the phenomenon of filter screen 6 jam, so need make filter screen 6 rotate, cooperate with scraper blade 8, scrape the solid impurity on the filter screen 6 down, so need the cooperation of drive assembly 9, drive assembly 9 is including rotatory ring 13 and rotatory piece 14, rotatory ring 13 is located the lower extreme position of water inlet 2, and rotatory ring 13 rotates with the inner chamber of jar body 1 to be connected, rotatory piece 14 is equipped with four, and the upper end of four rotatory pieces 14 all with the lower extreme fixed connection of rotatory ring 13, the lower extreme all with filter screen 6 fixed connection.

Further, since the driving unit 9 is rotatable, the rotation block 14 is spirally provided, and the sewage falls down to impact the rotation block 14, thereby rotating the rotation block 14.

Further, in order to make the water flow impact the rotating block 14, the rotating block 14 can be rotated better, so the position of the water inlet 2 in the tank body 1 is provided with the spiral strip 15, and the spiral direction of the spiral strip 15 is opposite to that of the rotating block 14.

The working principle is as follows: when carrying out the blowdown to the sewage in the steam pocket, through the button on the press control ware 4, controller 4 will open two solenoid valves, sewage gets into from water inlet 2, flow through spiral 15 clockwise rotations and get into jar body 1, strike rotatory piece 14, rotatory piece 14 drives rotatory ring 13 thereupon and rotates, filter screen 6 that the lower extreme is fixed is rotatory in ring baffle 7 thereupon, strike on rotatory piece 14 sewage comparatively evenly scatters filter screen 6 thereupon, the solid impurity in the sewage is filtered out by filter screen 6, and roll on ring baffle 7, the solid impurity of card on filter screen 6 passes through the cooperation between rotatory filter screen 6 and scraper blade 8, scrape it and fall, the sewage that has filtered is discharged through delivery port 3 thereupon.

The control mode of the utility model is automatically controlled by the controller, and the control circuit of the controller can be realized by simple programming of technicians in the field, which belongs to the common knowledge in the field, so the utility model does not explain the control mode and the circuit connection in detail.
