Abstract

The utility model discloses a spray gun driving machine, which comprises a frame with a spray gun guiding sleeve. A plurality of clamping wheels used for clamping a high-pressure water spray gun are mounted on the frame and distributed on at least two lateral sides of a high-pressure water spray gun passage, and at least one clamping wheel of the clamping wheels is connected with a water gun driving electromotor by the aid of a mechanical transmission device. The spray gun driving machine is suitable for clamping the high-pressure water spray gun to clean and descale heat exchange tubes of a tube-type heat exchanger and has the advantage that labor intensity is greatly reduced compared with the prior art.

Description

The spray gun driving machine

Technical field

The utility model relates to cleaning equipment manufacturing technology field, specifically a kind ofly controls high-pressure water spraying gun carries out jet cleaning and scale removal to the heat exchanger tube of tubular heat exchanger machine.

Background technology

Heat exchanger in use often forms dirt easily in heat exchanger tube, influence heat exchange efficiency, most typical is heat exchanger in the evaporator of sugar refinery, tubular heat exchanger in this evaporator has nearly 5000～8500 heat exchanger tubes that vertically are provided with, in the liquid glucose evaporation process, very easily at the heat exchanger tube encrustation, to such an extent as to all will clean once every day to this.In existing technical scheme, cleaning equipment is to be made of by the high-pressure water spraying gun that high-pressure water pipe is communicated with a high-pressure hydraulic pump, the jet exit of high-pressure water spraying gun makes the emitted High-Pressure Water of high pressure water jets gun sprayer that is in the heat exchanger tube wash away the inwall of heat exchanger tube around the high-pressure water spraying gun barral of a gun.Using this equipment is to manage this tool high-pressure water spraying gun by manually-operated the heat exchanger tube of the tubular heat exchanger of evaporator is inserted jet cleaning downwards by root upwards to extract out to the cleaning method of evaporator, on the hydraulic giant bar, be with the protective cover of a tubular, when the hydraulic giant head goes out outside heat exchanger tube, rely on protective cover to block current to the side direction ejection in case injure the operator.The heat exchanger labour intensity that cleans in the evaporator with this equipment is very big, repeating up and down operate high pressure water spray gun stroke reaches several meters heat exchanger tubes to several thousand and cleans, operation element is very heavy, also the leakage that the exchange heat pipe takes place is easily washed, fouling is with even more serious once more for the heat exchanger tube that this leakage is washed, and also difficulty is cleaned.

Summary of the invention

Problem to be solved in the utility model provides a kind of spray gun driving machine, and this spray gun driving machine can solve the big problem of existing cleaning equipment operation labour intensity.

In order to address the above problem, the technical solution of the utility model is: this spray gun driving machine has a frame with spray gun fairlead, a plurality of clamping wheels that are used for the clamping high-pressure water spraying gun are housed on frame, these clamping wheels divide two sides that are listed in the high-pressure water spraying gun passage at least, have at least a clamping wheel to be connected with a hydraulic giant drive motor by mechanical driving device in the middle of these clamping wheels.

Above-mentioned spray gun driving machine more specifically technical scheme can also be: described each clamping wheel is fixedlyed connected with its wheel shaft, and be contained on the described frame by bearing, described these clamping wheels are divided into setting two rows are set, and be arranged in the two sides of high-pressure water spraying gun passage respectively, described mechanical driving device is a chain gearing, and the wheel shaft of each clamping wheel all is connected with the sprocket wheel of described mechanical driving device.

Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect: labour intensity is little, operative employee person is when cleaning operation, only need the controlling electric device gauge tap, can implement the tubular heat exchanger in the evaporator or other tubular heat exchanger are carried out cleaning and descaling, operation is light and handy.

The mark of parts is as follows among above-mentioned each figure:

The 1st, the hydraulic giant drive motor; The 2nd, reductor; The 3rd, frame; The 4th, directive wheel; The 5th, the swing guide; The 6th, last fairlead; The 7th, chain gearing; The 8th, wheel shaft; The 9th, the clamping wheel; The 10th, following fairlead; The 11st, the tubular protective cover; 12,13 and 14 is pulleys.

The specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawing example:

Fig. 1, Fig. 2 and spray gun driving machine shown in Figure 3, a frame 3 is arranged, hydraulic giant drive motor 1 and reductor 2 are equipped with in the top of frame 3, it below frame 3 casing, the chain gearing 7 that is made of chain, drive sprocket, driven sprocket, jockey sprocket, drag chain wheel shaft etc. is housed in it, general headquarters' one side is connected with a last fairlead 6 that is used to install high-pressure water spraying gun on the frame 3, swing guide 5 is equipped with by bearing in the upper end of last fairlead, on the swing guide 5 directive wheel 4 that installs the high-pressure water spraying gun water pipe is housed; One side of frame 3 chest portion is connected with a following fairlead 10 that is used to install high-pressure water spraying gun, and the lower end of following fairlead 10 is set with a tubular protective cover 11 versatilely; By bearing 6 wheel shafts 8 are housed on the side plate of frame 3 phase bodies, every wheel shaft 8 is fixedly connected with an a plurality of clamping wheel 9 that is used for the clamping high-pressure water spraying gun by flat key, the wheel face of each clamping wheel 9 all is to be made by rubber, and has a groove, two rows that 6 clampings wheel 9 is lined up setting respectively divide the both sides that are listed in by the passage of last fairlead 6 and following fairlead 10 determined high-pressure water spraying guns, fixedly connected with the driven sprocket of a chain gearing 7 respectively in the inner that 6 wheel shafts 8 stretch into frame 3 chest portion.By wheel shaft the

pulley

12,13,14 that is used to be articulated on the moving frame (part that the utility model is outer) is housed on another side plate of frame 3 chest portion.

When this machine of use clamping high-pressure water spraying gun carries out the cleaning and descaling operation to the heat exchanger tube of tubular heat exchanger, operating personnel are as long as open the switch that high-pressure water spraying gun connects water pump, moving frame 3, perhaps by frame 3 is contained on the walking machine, high-pressure water spraying guns in the following fairlead 10 are aimed at the heat exchanger tube of wanting cleaning and descaling, the button of unlatching control hydraulic giant drive motor 1 rotating just can be handled high-pressure water spraying gun and stretch into or withdraw from heat exchanger tube, realizes water spray flush clean, the scale removal of heat exchanging inside pipe wall.
