Abstract
The utility model relates to a rotary bar injective dredger for a pipe rack heat exchanger. The dredger includes a drill bit, a drill stem, a rotary connector and a driving unit. Water spray hole is arranged on the drill bit. The drill stem, drill bit and rotary connector are in screw-thread connection. The utility model is very convenient for disassembly, installation and portability and provides good dredge performance on grease stems.
Description
Technical field
The utility model relates to a kind of pipe-dredging cleaning apparatus, particularly a kind of bull stick injection formula tubular heat exchanger pipeline drainer.
Background technology
In the enterprise, particularly chemical enterprise that use pipe heat exchanger, when the heat exchanging device carries out physics mediation cleaning, typically use the waterpower mediation and clean, carry out operation by special equipment and professional operating personnel.Its operation principle: be by the reaction force that the water under high pressure contra-injection is produced shower nozzle to be headed in the pipe, water is removed the tube wall dirt in the dirt in shower nozzle heads into pipe.
It is big that prior art has an equipment scale, and investment is big, and environmental pollution is big, and defectives such as poor safety performance are less than normal relatively to general medium-sized and small enterprises or mediation workload, the place of dispersion, and its economy, the defective on the promptness is outstanding further flexibly.Therefore can cause the heat exchanger of part enterprise can not effectively dredge cleaning timely.
Prior art is washed away the dirt that extrudes in the pipeline by the water under high pressure active force, and is lower to lipid dirt mediation ability.
Summary of the invention
For addressing the above problem, the utility model provides a kind of safe, portable, heat exchanger tube dredge that the mediation ability is strong, and by dirt in the drill bit rotation scraping pipe, and water spray takes away the dirt bits that scrape, to reach the purpose of cleaning and dredging heat exchanger tube.
For achieving the above object, heat exchanger tube dredge of the present utility model comprises drill bit, drilling rod, swivel joint, actuator, and described drill bit is provided with hole for water spraying, and described drilling rod and drill bit, swivel joint are by being threaded.
Described swivel joint comprises central shaft, bearing, water inlet.
Described actuator adopts pneumatic or motorized motions.
Prior art is because of having certain danger, and the operator needs the professional through certain technical training, heat exchanger tube dredge technical security performance height of the present utility model, and any operating personnel get final product operation through simple declaration.Heat exchanger tube dredge of the present utility model is dismantled, installs very convenient, is easy to carry about with one, and the lipid tamper is had stronger mediation ability.
Heat exchanger tube dredge applicable surface of the present utility model is wider, and suitable operating personnel, maintainer dispose as routine, also can be used as the attached configuration that specialty is cleaned.
Description of drawings
Fig. 1 is the schematic diagram of heat exchanger tube dredge of the present utility model;
Fig. 2 is the structural representation of swivel joint.
The specific embodiment
Fig. 1 is the schematic diagram of heat exchanger tube dredge of the present utility model, and as shown in the figure, the heat exchanger tube dredge comprises drill bit 1, drilling rod 2, swivel joint 3, actuator 4, external water pipe 5, power source access port 6.
Drill bit 1 and drilling rod 2 be by being threaded, and drill bit 1 is provided with hole for water spraying (among the figure sign).Drilling rod 2 adopts steel pipe, and two ends are connected with swivel joint 3 with drill bit 1 respectively, and bar length can come according to the actual requirements to determine that drilling rod 2 internal run-throughs are used for water guide.Drilling rod 2 and swivel joint 3 are by being threaded.
Swivel joint 3 is used for jointed rod. water pipe and rotary drive.Fig. 3 is the structural representation of swivel joint.As shown in the figure, swivel joint 3 comprises central shaft 31, bearing 32, water inlet 33.
Actuator 4 is connected with swivel joint 3, drives drilling rod 2.Actuator can adopt pneumatic, and is electronic or manual.
When heat exchanger tube dredge of the present utility model uses, at first actuator, external water pipe, swivel joint are connected, preliminary operation behind connection power source and the water, determine to install firmly, direction of rotation errorless after, select for use drill bit, drilling rod to be installed on the swivel joint according to heat exchanger caliber, length again.Power source can be selected for use pneumatic or electronic as requested.
Earlier bit head is inserted certain depth in the pipe (safety location) during operation and driven revolving part again, drilling rod, drill bit rotation, the operator holds swivel joint drilling rod is pushed in the heat exchanger tube slowly, and the water that the tamper in the exchanger tube wall is imported in the drilling rod after being descended by the drill bit scraping is immediately gone out.
The utility model is by dirt in the drill bit rotation scraping pipe, and therefore less demanding to hydraulic pressure only needs to take away the dirt bits that scrape and get final product, and the lipid tamper is had stronger mediation ability.
