Description

Dry Ice Cleaner {Dry Ice Cleaner}

The present invention relates to a dry ice washer that cleans various machinery and facilities by spraying the dry ice particles at high speed with compressed air. In particular, the dry ice can be more smoothly discharged dry ice particles filled in the hopper Relates to an ice washer.

Many years of field application and research have led to the development of many technologies for powerful dry ice sprayers. This technology meets the demand for a new effective cleaning system in today's industry that can clean entire highways without causing environmental pollution.

Dry ice particle injector removes foreign substances by spraying hard dry ice particles which are harmless to industrial facilities and environment at high speed. By controlling the amount and speed of dry ice sprayed to some extent, it is possible to remove foreign substances adhering to the surface of devices and products made of various materials such as ceramics, synthetic resins, rare metals, fiberglass, rubber, plastics, steel, etc. . As soon as the dry ice particles hit the surface, they are sublimed into a harmless gas, removing only foreign substances and leaving no secondary contaminants or moisture, without damaging the cleaning surface.

Dry ice cleaning extends the life of the equipment, thereby reducing the investment costs for new dies, molds and molds. This reduces the time required for cleaning operations and the time and cost of collecting and treating secondary contaminants from conventional cleaning, thereby reducing overall operating costs. It is now possible to completely clean production equipment or products without using volatile organic solvents (VOCs), substances that damage the ozone layer (ODS), and solvents that cause waste water, which are prohibited from use in environmental protection regulations on industrial sites. .

Dry ice cleaning is widely used in all industrial fields such as food processing, confectionery, rubber, plastics, pharmaceuticals, automobile manufacturing, aircraft maintenance, aerospace, electrical and electronics, semiconductor industry, petrochemical, steelmaking, printing and foundry industry. . In all industries that still rely on conventional cleaning operations such as short blasting, steam cleaning, solvents, or hand scraping, dry ice cleaning is used to reduce costs, improve productivity, improve quality, and protect the environment. Of course, by ensuring a safe and clean working environment can prevent workers from frequent transfers or turnover due to occupational diseases.

Looking at the conventional dry ice washer having the advantages described above, as shown in Figure 1, the frame plate 2 is supported in the case and the discharge hole (2a) in the vertical direction, and fixed to the upper and the upper side of the frame plate (2) Guide plate 3 having guide groove 3a in the direction, and guide groove 3a of guide plate 3 settled together with pad 4a, and sliding by the cylinder 4b in left and right directions, and up and down direction Sliding bar (4) with three inlet holes (4c) and the upper part is wide and the lower part is formed narrowly and has an outlet (5a) at the lower end connected to the left and right inlet hole (4c) of the slide bar (4) The hopper 5 and one end thereof are connected to the discharge hole 2a of the frame plate 2 through the inlet hole 4c of the sliding rod 4, and the other end thereof is connected to the compressor 6a so as to provide compressed air. Blowing compressed air hose (6) and one end thereof is connected to the lower portion of the discharge hole (2a) of the frame plate (2) And the other end is composed of a jetting hose (7) connected to the minute case.

The conventional washing machine configured as described above naturally falls when the dry ice particles put into the hopper 5 coincide with the inlet hole 4c of the sliding bar 4 through the outlet port 5a. When the cylinder 4b and the compressor 6a are driven, dry ice is injected into the spray hose 7 by the high pressure air injected from the compressor 6a when the slide rod 4 is reciprocated to the discharge hole 2a. It is to wash by colliding with the surface of the object to be cleaned through)

However, in the related art, the dry ice filled in the hopper 5 is drawn into the inlet hole 4c by the natural drop through the outlet 5a. Because cold dry ice freezes on the lower inner wall of the hopper 5 including the outlet 5a, it does not fall smoothly. Therefore, from time to time to scrape the inner wall of the lower hopper using a specific tool has a problem of poor workability.

SUMMARY OF THE INVENTION An object of the present invention is to provide a dry ice washer that can allow the dry ice in the hopper to be drawn into the inlet hole drilled in the sliding rod through the outlet.

Hereinafter, the technical configuration of the present invention in detail.

2 and 3, the dry ice washer of the present invention is supported in the case 10 and fixed to the frame plate 20, the discharge hole 21 in the vertical direction and the frame plate 20, the upper portion And a guide plate 30 having a guide groove 31 in the left and right directions, and placed in the guide groove 31 of the guide plate 30, and slidable in the left and right directions by the cylinder 42. 43 and the hopper 50 is connected to the left and right inlet hole 43 of the sliding rod 40, the upper portion is wide and the lower portion is formed narrow and has an outlet 51 at the lower end thereof; One end thereof is connected to the discharge hole 21 of the frame plate 20 through the inlet hole 43 of the sliding rod 40 and the other end thereof is connected to the compressor 61 to blow the compressed air. Air hose 60 and one end thereof is connected to the lower portion of the discharge hole 21 of the frame plate 20 and the other end thereof In that the consist of the injection hose (70) connected to the gun (71) is no different by the conventional technical concept.

However, it is characterized in that the inlet means 80 for forcibly introducing the dry ice into the inlet hole 43 of the sliding bar 40 in the lower portion of the outlet 51 of the hopper (50).

A specific embodiment of the pulling means 80 is as shown in Figures 4 and 5, the pulling means 80 is a small diameter in the upper side is coupled to the outlet 51 of the hopper 50 made of a large diameter However, the coupling pipe 81 forms a stepped portion 81a between the small diameter and the large diameter, and has a structure that is inserted into and coupled to the stepped portion 81a of the coupling pipe 81, but has an air passage 82a at the upper outer periphery. While forming a protruding ring (82b) on the upper edge and the inner periphery of the protruding ring (82b) is formed to be inclined inward and the air connected to the large diameter upper portion of the coupling pipe (81) The hose 83 is shown.

Here, the step (81a) serves to reverse the flow of the air flowing to the upper portion of the lower portion of the insertion tube (82). In addition, the inner circumference of the protruding ring 82b is formed to be inclined inward, and serves to guide the inside of the insertion tube 82 while the air blocked by the step 81a flows backward.

Referring to the coupling state of the inlet means 80, as shown in Figure 5, the insertion tube 82 is inserted into the lower portion of the coupling tube 81, and finally screwed. Protruding ring 82b constituting the upper edge of the insertion tube 82 is not in close contact with the step (81a) of the coupling tube 81 is coupled in close proximity while leaving a slight gap (s). And the flange (82c) formed on the lower outer peripheral surface of the insertion tube 82 is tightly coupled to the lower end of the coupling tube (81).

Looking at the air flow of the inlet means 80, the high-pressure air injected from the air hose 83 and the protruding ring 82b along the air passage (82a) formed between the coupling pipe 81 and the insertion pipe 82 and Flowing upward through the gap (s) between the step (81a) is blocked by the step (81a) and flows back into the lower insertion tube 82 again. Therefore, the flow of air by the inlet means 80 is injected at a high pressure in the air hose 83, and again sprayed more strongly while passing through the gap (s) is injected into the lower portion of the insertion tube (82). At this time, the air in the outlet 51 and the lower portion of the hopper 50 is sucked by the force injected into the lower portion of the insertion tube 82, the dry ice is forcibly drawn into the inlet (43).

Dry ice washing machine of the present invention by installing a draw means (80) consisting of a coupling pipe 81 and the insertion tube and the air hose 83 in the lower portion of the outlet 51 of the hopper 50 sliding bar ( 40 has an effect of forcing the lead into the insertion hole 43.
