Description

High-speed filter with calandria water collection device

Technical Field

The utility model relates to a sewage filtration technology, especially a sewage filter, specifically speaking are high-speed filter with calandria water-collecting device.

Background

The high-speed filter uses quartz sand and anthracite as filter material to filter out the suspended matter with turbidity in water, ensuring that the turbidity in the water meets the requirement of industrial waste water drainage. The working principle is that raw water enters a central pipe from the bottom of a filter, the water is uniformly distributed to a filter layer surface through a water distribution device on the upper part of the central pipe, the water is intercepted and filtered through filter material layers with different gradation, the water is collected through a water collecting device, and then the water is discharged outwards from a water outlet pipe of an equipment body, as shown in figure 1. When the impurities are accumulated in the filter material layer to reach a certain set limit, the system can be automatically switched to a backwashing state to clean the accumulated impurities. However, the water collecting device of the high-speed filter with the structure adopts a structure of the porous plate and the drainage cap, as shown in fig. 2, the structure is complicated during the manufacturing process, the porous plate is connected with the cylinder body and is difficult to have no defects, and if a gap exists at the welding position, sewage flows out and is discharged without being treated. When the drainage cap 11 is used for filtering, the drainage gap is only about 1mm, and the drainage cap is easily blocked by filter materials. Because the drain cap blocks up when the backwash, pressure during the backwash will make the perforated plate warp and lead to the equipment body also to warp, forms the potential safety hazard to influence the normal operating of equipment. The water discharging cap is a thin plastic product, the water discharging cap is damaged due to long-term operation, equipment needs to be overhauled after a long time, and the water collecting device brings certain difficulty to overhaul at the bottom of the equipment.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problems that the water collecting device of the perforated plate and the drain cap structure adopted by the existing high-speed filter is short in service life, the drain cap is damaged and the like, and designing the high-speed filter with the calandria water collecting device is convenient in backwashing and long in service life.

The technical scheme of the utility model is that:

The utility model provides a high-speed filter with calandria water-collecting device, it includes barrel 6 and center tube 2, and the lower part of center tube 2 is linked together with the inlet tube 1 that stretches out outside the barrel, and water distribution device 3 is installed on the upper portion of center tube 2, and characterized by is equipped with calandria water-collecting device 5 that bears filter material layer 10 in barrel 6, and this calandria water-collecting device 5 is divided into the water portion of straining on upper portion and the clear water portion of lower part with barrel 6, clear water portion be connected with drain pipe 4.

The calandria type water collecting device 5 is composed of calandria with 5mm intervals, two ends of each calandria are welded and fixed on the inner wall of the cylinder body, and the diameter of the calandria is 50 mm.

The calandria adopts stainless steel pipes or common steel pipes according to the corrosion degree of the sewage.

The upper portion of barrel be equipped with the upper portion manhole 8 of overhauing usefulness, the bottom is equipped with the bottom manhole 9 of overhauing usefulness.

The top of the cylinder body is provided with an exhaust port 7.

The distance L = phi/4 between the center of the calandria and the bottom of the cylinder body, and phi is the inner diameter of the cylinder body.

The utility model has the advantages that:

The utility model discloses a welding of calandria and barrel is easier than original perforated plate welding, and the welding is convenient, but more firm. The calandria is evenly welded inside the cylinder body, plays a certain reinforcing role to the cylinder body, and the filter can not lead to the deformation because the water pressure is too big during the backwash.

The utility model discloses a be 5mm between calandria and the calandria, both can not blockked up by the filter material, do benefit to the water collection and handle, also be favorable to the back flush, shorten the backwash time. The operation cycle is long, basically need not maintain, and the preparation is convenient, energy-conserving cost reduction.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

as shown in fig. 3-4.

The utility model provides a high-speed filter with calandria water-collecting device, it includes barrel 6 and center tube 2, the lower part of center tube 2 is linked together with the inlet tube 1 that stretches out outside the barrel, water distribution device 3 is installed on the upper portion of center tube 2, the top of barrel 6 is equipped with exhaust hole 7, upper portion is equipped with overhauls and uses upper portion manhole 8, the bottom is equipped with overhauls and uses bottom manhole 9, as shown in figure 3, characterized by is equipped with calandria water-collecting device 5 who bears filter material layer 10 in barrel 6, this calandria water-collecting device 5 is divided into the filter water part on upper portion and the clear water part of lower part with barrel 6, clear water part. The utility model discloses a calandria formula water-collecting device 5 comprises the calandria that the interval is 5 millimeters, as shown in figure 4, the equal welded fastening in both ends of every calandria is on the barrel inner wall, and the diameter of calandria is 50 millimeters. The calandria adopts stainless steel pipes or common steel pipes according to the corrosion degree of the sewage. The distance L = phi/4 between the center of the calandria and the bottom of the cylinder body, and phi is the inner diameter of the cylinder body.

As shown in fig. 4, the water collecting device of the present invention is a new type of calandria water collecting device with uniform arrangement. The calandria can be according to the quality of water of raw water, chooses for use the pipeline (304L stainless steel pipe or ordinary type welded tube) of DN50 of different materials, leaves 5 mm's clearance between calandria and the calandria, and the align to grid is favorable to passing through the smooth water-collecting device of sewage in filter material layer like this, and 5 mm's clearance also can not blockked up by the filter material. The apparatus body may have different specifications according to the treatment amount of raw water. The calandria is arranged in the body, and the distance from the bottom of the body is determined by the size of the equipment (L = phi (diameter of the equipment body)/4). Compared with the original porous plate, the welding of the calandria and the equipment body is easy, convenient and firm. The calandria is evenly welded inside the body, plays certain reinforcing effect to the body, and equipment can not lead to the deformation because the water pressure is too big during the backwash. The device has long running period, basically does not need maintenance, is convenient to manufacture, and saves energy and reduces cost.

The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
