Problems solved by technology

[0004] Another example is in the field of sewage chemical reaction precipitation, due to the heavy density of chemical sludge, and the addition of viscous polyacrylamide and other flocculants during chemical reactions, it will also cause sludge to adhere to inclined plates, and in severe cases, sludge may even lead to inclined plates. collapse of the board

Embodiment 1

[0033] Such as Figure 1-3 As shown, it is a self-cleaning device for a sedimentation tank inclined plate provided by the present invention, which includes a sedimentation tank inclined plate housing 1, a number of inclined plates 2 arranged evenly above the sedimentation tank through card slots, and arranged on both sides of the sedimentation tank top. The traveling track 3, the traveling trolley 4 arranged on each traveling track, the main beam track 5 arranged between two traveling trolleys 4, the main beam track trolley 5-1 arranged on the main beam track 5, the main beam track trolley 5-1 arranged on The telescopic push rod 6 on the main beam track dolly 5-1, the replaceable scraper 7 that is arranged on the telescopic push rod 6 ends, the telescopic push rod 6 is obliquely installed, and the inclination angle is consistent with the inclination angle of the swash plate 2.

[0034] Such as Figure 4-5 As shown, the swash plate 2 is evenly connected with the card slots, an...

Embodiment 2

[0039] This embodiment provides a method for using the self-cleaning device for the sloping plate of the sedimentation tank provided in the embodiment, including the following steps:

[0040] 1) The traveling trolleys 4 on both sides walk freely left and right on their corresponding traveling rails 3, and sense whether the positioning of the traveling trolley 4 matches the slant plate 2 through the displacement sensor at the front end. acceptable range;

[0041] 2) The traveling trolley 4 laterally moves forward and backward on the main beam track 5 to drive the telescopic push rod 6 and the replaceable blade 7 to move left and right along the sedimentation tank, so as to clean different positions of the swash plate;

[0042] 3) When the telescopic push rod drives the replaceable shovel 7 installed at the front end to push out, the shovel pushes the mud obliquely downward, and pushes the sludge on the sloping plate 2 into the bottom of the sedimentation tank; After the plate ...

Abstract

The invention provides a self-cleaning device for an inclined plate of a sedimentation tank and a using method of the self-cleaning device. The device comprises a sedimentation tank inclined plate shell, a plurality of inclined plates uniformly arranged above a sedimentation tank at intervals through clamping grooves, advancing tracks arranged on two sides of the top of the sedimentation tank, advancing trolleys arranged on the advancing tracks, a main beam rail trolley arranged on a main beam rail, a telescopic push rod arranged on the main beam rail trolley and a replaceable scraper knife arranged at the end of the telescopic push rod. The self-cleaning device for the inclined plate of the sedimentation tank can automatically shovel mud and accurately carry out positioning to prevent the scraper knife from being in contact with and damaging the inclined plate, the form of a scraper knife head can be replaced, the scraper knife head can rotate and can be washed by spraying water, accumulated mud is prevented from blocking an ascending channel, different sludge requirements are met, and the treatment capacity is improved. The inclined plate of the device is clamped to a clamping groove, so that the inclined plate is a movable inclined plate, the inclined plate is detachable, and the position of the inclined plate can be finely adjusted.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a self-cleaning device for a slant plate in a sedimentation tank and a use method thereof. Background technique [0002] Due to its small footprint and high separation efficiency, inclined plate sedimentation tanks are widely used in the field of sewage treatment and are one of the most common sedimentation methods. However, the inclined plate of the inclined plate sedimentation tank is easy to adhere to and accumulate particles, which seriously affects the effective cross-sectional area of ​​the ascending channel in the inclined plate area and the separation efficiency of the sedimentation tank, and greatly limits the scope of application of this pool type. [0003] For example, in the field of sewage biochemical treatment, activated sludge has strong viscosity and is extremely easy to adhere to the sloping plate, which often leads to the obstruction of the ...
