Description

Technical Field

[0001] The utility model relates to the technical field of energy-saving sewage discharge equipment, and more specifically, to an energy-saving sewage discharge device for industrial boilers. Background Art

[0002] The purpose of boiler blowdown is to ensure that the water quality of the boiler meets the specified standards, reduce the adverse effects of scale formation on the boiler, and keep the impurities in the water within a certain concentration. It is necessary to continuously discharge boiler water with high salt and alkali content and deposited residues, sludge and various sediments from the boiler to maintain safe operation of the boiler and extend the service life of the boiler.

[0003] When the boiler is discharging sewage, the sewage needs to be filtered first. When the filter is filtering, the filter screens set on the left and right will shake under the impact of the sewage, affecting the filtration. In addition, after the filter screen is used for a long time, the sludge in the sewage will clog the mesh of the filter screen. If it cannot be cleaned in time, the normal filtration will be affected. The filter screen also needs to be replaced continuously, which is troublesome. Therefore, in view of the above problems, an energy-saving sewage discharge device for industrial boilers is specially proposed. Utility Model Content

[0024] In order to make the technical means, creative features, objectives and effects achieved by the utility model easy to understand, the technical scheme in the specific implementation mode of the utility model is clearly and completely described below to further illustrate the utility model. Obviously, the specific implementation mode described is only a part of the implementation mode of the utility model, rather than all styles.

[0025] Example:

[0026] The following is combined with Figure 1-4 The utility model is described in further detail.

[0027] See also Figure 1-4 The utility model provides a technical solution: an energy-saving sewage discharge device for an industrial boiler, comprising an industrial boiler 1 and a filter box 2, a sewage discharge groove 13 is provided at the bottom of the inner wall of the filter box 2, and one end of the sewage discharge groove 13 is connected to a sewage discharge valve 14, and the sewage discharge valve 14 is installed on the filter box 2. Through the setting of the sewage discharge groove 13 and the sewage discharge valve 14, the cleaned and filtered sludge can be discharged from the filter box 2.

[0028] The industrial boiler 1 is connected to the filter box 2 through a connecting pipe 7. A filter screen 10 is clamped on the filter box 2. A baffle 4 is fixedly connected to the top of the filter screen 10. Two fixing grooves 18 are provided on the baffle 4. A fixing ring 17 is welded to the top of the filter box 2. One end of the fixing ring 17 passes through the fixing groove 18 and is located above the baffle 4. An electric push rod 5 is welded to the top of the filter box 2 through a mounting plate. A fixing plate 19 is welded and fixed to one end of the electric push rod 5. The fixing plate 19 is fixedly arranged with the fixing ring 17. A brush plate 9 is connected to the filter box 2 through a lifting assembly. One side of the brush plate 9 is connected to one side of the filter screen 10. The two are tightly against each other. When the brush plate moves up and down, the brush on the brush plate can be inserted into the mesh of the filter. The other side of the filter box 2 is connected to a water pump 6, and the output end of the water pump 6 can be connected to the neutralization device in the sewage discharge device. Under the joint action of the baffle 4, the fixed groove 18, the fixed ring 17, the fixed plate 19 and the electric push rod 5, the fixed groove 18 can be clamped with the fixed ring 17, and the fixed plate 19 can be clamped and fixed with the fixed ring 17, so that the filter 10 can be fixed on the filter 10, thereby avoiding the occurrence of poor filtering effect due to the shaking of the filter 10.

[0029] Specifically, the lowering component includes a motor 3, a sliding rod 12 and a bearing, and the bearing is embedded in the filter box 2. A rotating shaft 16 is movably inserted in the bearing. The top of the rotating shaft 16 is connected to the motor 3 through a coupling. The body of the motor 3 is welded to the top of the filter box 2 through a fixing plate 19. The bottom end of the rotating shaft 16 is fixedly connected to a threaded rod 8, and a threaded barrel is threadedly connected to the threaded rod 8. The sliding rod 12 is welded and fixed to the inner wall of the filter box 2. A sliding sleeve 11 is slidably connected to the sliding rod 12, and a filter screen 10 is welded between the sliding sleeve 11 and the threaded barrel 15.

[0030] By adopting the above technical solution, under the joint action of the motor 3, the threaded rod 8, the sliding rod 12, the sliding sleeve 11, the threaded cylinder 15 and the brush plate 9, the motor 3 works to rotate the threaded rod 8, so that the brush plate 9 can move upward or downward, so that the brush plate 9 can clean the filter screen 10, thereby ensuring the normal operation of the filter screen 10.

[0031] The working principle of the utility model is as follows: when in use, the electrical appliance is connected to the external controller. When the filter screen 10 is cleaned, the controller controls the motor 3 to rotate with the threaded rod 8. Under the limit of the slide rod 12 and the sliding sleeve, the threaded cylinder 15 moves on the threaded rod 8, so that the filter screen 10 can be cleaned with the brush plate 9 to avoid sludge clogging in the mesh. The sludge cleaned from the filter screen 10 will be collected in the sewage tank 13, and then the sewage valve 14 will be opened regularly to discharge the sludge.

[0032] When the filter 10 is replaced, the electric push rod 5 moves with the fixing plate 19 to separate the fixing plate 19 from the fixing ring 17, and then the baffle 4 is pulled upwards, so that the filter 10 can be taken out.
