specific Embodiment approach 1

[0007] Specific implementation mode one: (see Figure 1 ~ Figure 2 ) This embodiment includes outlet flange 1, inlet sleeve 2, inlet short pipe 14, outer cylinder 3, inner cylinder 4, hand hole flange 5, sewage outlet 6, rectification orifice plate 7, inlet flange 8, coaxial sleeve 9 and the water outlet pipe 10, the sewage outlet 6 is connected to the bottom of the outer cylinder 3, the lower end of the coaxial sleeve 9 communicates with the upper end of the outer cylinder 3, the upper end of the coaxial sleeve 9 communicates with the lower end of the inlet sleeve 2, and the inlet method The flange 8 is fixedly connected to the inlet short pipe 14 at the front end of the inlet casing 2, the outlet pipe 10 is arranged in the inlet casing 2 and the coaxial casing 9, the outlet pipe 10 is fixedly connected to the inlet casing 2, and the inner cylinder 4 is arranged outside The upper part of the cylinder 3, the bottom of the inner cylinder 4 is open, the upper end of the outlet p...

specific Embodiment approach 2

[0008] Specific implementation mode two: (see Figure 1 ~ Figure 2 ) In this embodiment, the diameter 12 of the rectifying orifice plate 7 is 1 cm to 3 cm. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0009] Specific implementation mode three: (see Figure 1 ~ Figure 2 ) The tube diameter of the upper end of the outer tube 3 in the present embodiment is the same as the tube diameter of the lower end of the outer tube 3 . Others are the same as in the second embodiment. The dirt accumulation buckets of the existing decontamination devices are conical, and the height of the decontamination device must be lengthened due to the small space of the cone. In this embodiment, the bottom of the tube and the top of the tube have the same size, which increases the capacity of the bottom of the tube, not only reduces the height of the decontamination device, but also reduces the volume of the decontamination device.

Abstract

The invention relates to a double-cylinder dirt separator. The aim of the invention is to solve the problem that the prior dirt separator fails to achieve a required dire separation effect during use, is susceptible to blockage caused by large-sized dirt and flotage and has a short maintenance period, uneasy maintenance and influence on heat supply effect when a larger amount of impurities exist in a heat supply system. The lower end of a coaxial sleeve pipe of the dirt separator is communicated with the upper end of an outer cylinder, the upper end of the coaxial sleeve pipe is communicated with the lower end of an inlet sleeve pipe, a water outlet pipe is arranged in the inlet sleeve pipe and the coaxial sleeve pipe, an inner cylinder is arranged on the upper part of the outer cylinder,the upper end of the water outlet pipe is fixedly connected with an outlet flange, and the lower end of the water outlet pipe is communicated with the upper end of the inner cylinder. The dirt separator can remove more than 90 percent of molding sand with a grain diameter of 1 millimeter under a condition of an inlet flow of less than 3m / s, and can remove more than 80 percent of molding sand witha grain diameter of 0.5 millimeter under a condition of an inlet flow of less than 2.0m / s.

Description

technical field [0001] The invention relates to a decontamination device. Background technique [0002] Due to the sticky sand in the inner cavity of the cast iron radiator used in the existing heating system, it continuously falls off during use. Since the particle size of the molding sand is very small, the decontamination device used in the existing heating system can remove it. The effect is not ideal. In order to solve the above problems, a utility model patent with the Chinese patent number ZL02210839.4, the authorized announcement number CN2535663Y, the authorized announcement date being February 12, 2003, and the name "centrifugal high-efficiency decontamination device" discloses a decontamination The decontamination device cannot achieve the decontamination effect described in the patent specification during use, and it is easy to block for larger dirt and floating objects. When there are many impurities in the heating system, the maintenance period of the deconta...
