Embodiment 1

[0039] Such as figure 1 and 2 As shown, a sludge discharge device for a water treatment facility is arranged at the bottom of the water treatment tank, and includes a sludge discharge hopper 2 at the bottom of the water treatment tank 1, and a sludge discharge pipe 3 with one end extending into the sludge discharge hopper And a swirl injection mechanism for generating swirl water flow in the mud discharge pipe.

[0040] Such as figure 1 As shown, the mud discharge bucket 2 is a truncated conical structure with a square top (consistent with the cross-sectional shape and size of the water treatment tank) and a circular bottom. , wherein the inclination angle between the side wall of the mud discharge hopper 2 and the horizontal plane is preferably 45°-60°, which is beneficial for the precipitated particles in the water treatment tank to slide down to the bottom of the mud discharge hopper along the side wall of the mud discharge hopper.

[0041] The sludge discharge pipe 3 is...

Embodiment 2

[0055] In this embodiment, in order to obtain a better mud discharge treatment effect, the corresponding layout is made for the setting position of the water supply main pipe, the setting position of the trumpet and the setting position of the mud discharge pipe, as follows:

[0056] The distance between the large end opening of the horn 5 and the bottom surface of the mud discharge bucket 2 is 0.5D-D, preferably D. The setting position of the water supply main pipe 10 is higher than the position where the large end opening of the horn 5 is located, wherein the distance between the water supply main pipe 10 and the large end opening of the horn 5 is 0.5D-D, preferably 0.5D. The setting position of the mud discharge pipe 3 is higher than the location of the water supply pipe 10, wherein the distance between the central axis of the mud discharge pipe 3 and the bottom surface of the mud discharge bucket 2 is 2D-3D, preferably 2.8D.

[0057] At the same time, the height of the liq...

Embodiment 3

[0061] In the actual construction process of the mud discharge device, according to the size of the bottom surface of the water treatment tank, a single mud discharge hopper or multiple mud discharge hoppers can be arranged in parallel in the treatment tank, that is, one or more mud discharge hoppers are installed in the treatment tank A plurality of sludge discharge devices form the sludge discharge system of the water treatment facility.

[0062] When a mud discharge device is arranged at the bottom of the water treatment tank, the top of the mud discharge bucket is arranged in cooperation with the side wall of the water treatment tank.

[0063] When multiple sludge discharge devices are installed at the bottom of the water treatment tank, multiple sludge discharge hoppers are arranged side by side at the bottom of the water treatment tank in sequence, and between the sludge discharge hoppers, between the sludge discharge hopper and the side wall of the water treatment tank a...

Abstract

The invention discloses a sludge discharge device and a sludge discharge system for a water treatment facility. The sludge discharge device comprises a sludge discharge hopper arranged at the bottom of a water treatment pool, a sludge discharge pipe with one end extending into the sludge discharge hopper and a swirl injection mechanism. The swirl injection mechanism is used for generating swirl water flow in the sludge discharge hopper; the swirl injection mechanism comprises a water supply main pipe and a plurality of spray pipes respectively arranged on the water supply main pipe; one end ofeach spray pipe is connected to the water supply main pipe, the other end of each spray pipe extends into the sludge discharge hopper, the spray pipes are uniformly distributed in the circumferentialdirection of the sludge discharge hopper, a certain included angle is formed between each spray pipe and the horizontal plane, one of every two adjacent spray pipes is arranged upwards relative to the horizontal plane, and the other spray pipe is arranged downwards relative to the horizontal plane. The sludge discharge device and the sludge discharge system can well solve the problems of poor sludge discharge effect and incomplete sludge discharge of the sludge discharge mode adopted by the existing water treatment equipment, and have the characteristics of compact structure, smoothness in sludge discharge, cleanness, thoroughness and high efficiency.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a sludge discharge device and a sludge discharge system for a water treatment facility. Background technique [0002] In the 1990s, waterworks and sewage treatment plants in the municipal water treatment industry developed rapidly in my country. With the rapid growth of my country's economy, local governments have paid more and more attention to environmental protection, especially for municipal waterworks and sewage treatment plants. The requirements are also constantly increasing. In recent years, many municipal design institutes and relevant experts at home and abroad have studied the ways, methods and devices of sludge (sewage) discharge in municipal water purification plants and sewage plants, and have made some achievements, but there is no one for the sludge discharge system. A relatively complete and reliable sludge discharge device system. In recent years, perfor...
