Description

A new type of sludge screening device

technical field

The utility model relates to the mechanical field, in particular to a novel sludge screening device.

Background technique

With the improvement of the level of science and technology, on the one hand, people's material life has been greatly enriched, but at the same time, it has also brought a lot of living and production waste, which has brought a great impact on the environment. Due to the aggravation of pollution and the destruction of the ecological environment, a large amount of silt has accumulated in the rivers of the city. If it is not cleaned up in time, it will have a serious impact on the safety of the waterway and the ecology. Urban river silt has the characteristics of large mud content, a lot of garbage, and high water content. The overall shape is plastic, which directly affects the subsequent harmless treatment of silt. At present, traditional vibrating screen machines and grid machines are not suitable for direct use in sludge screening; while the existing sludge screening process is often carried out during dredging, and manual sorting is often used, which is time-consuming and labor-intensive. The treatment of river sludge has brought difficulties.

In order to solve the above problems, the technical scheme adopted in the utility model is as follows:

A new type of sludge screening device, the new type of sludge screening device includes a screening machine, a sand conveyor, a sludge receiving hopper, a sludge screw conveyor and a diversion tank; the screening machine includes a feed port, a bracket, a first screen, second screen, first vibrating device, second vibrating device, gravel hopper, mud tank, screen drive, first washing unit and second washing unit; the first screen and the second screen The net is arranged on the support, the first screen is located above the second screen, the angle between the first screen and the horizontal plane is 25-45°, and the first screen is parallel to the second screen; The aperture of the first screen is 8-12mm, the aperture of the second screen is 4-6mm; the feed inlet is arranged on the top of the first screen, and the gravel hopper is arranged on the first screen the bottom of the bottom; the mud tank is arranged in parallel below the second screen; the first washing unit is arranged on the first screen, the second washing unit is arranged on the second screen, and the first vibrating device is arranged On the first screen, the second vibrating device is arranged on the second screen; the first screen and the second screen are synchronously connected with the screen transmission device respectively; the sand conveying device is arranged on the sand hopper directly below the outlet; the sludge receiving hopper is arranged at the bottom of the second screen, and the sludge screw conveying device is arranged directly below the outlet of the sludge receiving hopper; the diversion groove is arranged below the mud tank.

With the design of the above structure, when the sludge dredged by the cutter suction boat or cleaned by the grab bucket enters the feed port of the sludge screening device of the present utility model, the sludge starts to enter the first screen, and at this time the screen transmission drives the second screen. The first sieve and the second sieve move, and at the same time the first vibrating device is turned on, so that when the silt moves down along the slope of the first sieve, the sand with a particle size larger than the aperture of the first sieve continues to flow with the first sieve. The net moves, enters the gravel hopper, and then falls into the gravel conveying device from the outlet of the gravel hopper, and the sand whose particle size is smaller than the aperture of the first screen falls into the second screen; at this time, the activated second screen The vibrating device makes the sediment move downwards on the inclined surface of the second screen, and the particles with a particle size larger than the second hole stay on the second screen, and fall into the sludge hopper with the movement of the second screen, and then enter the sludge In the screw conveying device, the mud whose particle size is smaller than the hole diameter of the second screen falls into the sediment tank under the second screen, and then falls into the diversion tank for collection, thereby completing the treatment of the sludge. The first flushing unit and the second flushing unit can accelerate the separation of sand and sediment during the sludge treatment process, making the separated sand, sediment and mud system more simple without further treatment , saving manpower and material resources.

In the present utility model, the preferred solution is that the novel sludge screening device also includes a mud pool and a circulating water pump, the mud pool is arranged at the end of the diversion tank, the circulating water pump includes an inlet port and an outlet port, and the inlet port The outlet end is arranged in the mud pool, and the outlet end communicates with the first flushing unit and the second flushing unit respectively through pipelines.

In the present utility model, a preferred scheme is that the aperture of the first screen is 10 mm, and the aperture of the second screen is 5 mm.

In the present utility model, the preferred solution is that the included angle between the first screen and the horizontal plane is 30°.

In the utility model, the preferred solution is that the novel sludge screening device further includes a concrete pump, and the concrete pump is arranged at the end of the sludge screw conveying device.

Compared with the prior art, the beneficial effect of the utility model lies in that the new sludge treatment device of the utility model can screen and process the sludge at one time, and the treated sandstone, sediment and mud system are single, and do not need to be treated again , saving manpower and material resources, and reducing the cost of separation.

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.
