Abstract
A kind of sand blasting unit of improvement, comprise air compressor, connect the air jet pipe of air compressor, be arranged on the Jin Sha mechanism on air jet pipe, it is characterized in that, described Jin Sha mechanism comprises the first sand-feeding tube, be arranged on first on the first sand-feeding tube and enter sand valve, second sand-feeding tube, be arranged on second on the second sand-feeding tube and enter sand valve, go out sandpipe, the first described sand-feeding tube and the discharge end of the second sand-feeding tube are all communicated to out sandpipe, described air jet pipe outlet side is provided with rifle head, described rifle head comprises outer tube, interior pipe and breathable membrane, the shaking out of the outlet side end face of the outer tube of described rifle head and interior pipe holds end face distance to be greater than 1 millimeter and interior pipe does not stretch out outside outer tube, its effect makes the interior pipe of rifle head because the raw negative pressure of the high-speed air flow movable property of outer tube, sand is siphoned away by negative pressure and sprays along with high-speed air, because this device is the thrust utilizing negative pressure to produce, less than the thrust directly produced by compressed air, so the speed that abrasive material advances wants slow, this significantly reduces the wearing and tearing of abrasive material to equipment, equipment life is extended greatly.
Description
Technical field
The utility model relates to a kind of sand blasting unit, especially a kind of sand blasting unit of improvement.
Background technology
Traditional sand-blasting machine is arranged on jet pipe by a jet pipe with one and the sand tank be communicated with jet pipe forms.Need first to sieve sand sand loading again, the amount of labour is large.Traditional sand-blasting machine has often sprayed a tank sand will to stop sand loading again, increases the amount of labour.
Portioned product improves, such as Chinese patent discloses a kind of self sucking sand-blasting machine, application number: 200520126529.4, the applying date: 2005-12-29, its technical scheme is: in jet piece chamber, be provided with gas sand mixing valve, is provided with appendix and sediment transport pipe in gas sand mixing valve; Wherein, suction nozzle is communicated with appendix, and sand is communicated with gas sand mixing valve by sediment transport pipe.
The ingenious part of this technical scheme is spraying high-pressure gas to be sent the mode of sand to be modified to by forming negative pressure and the mode automatically sucked by sand at the pipe that shakes out.But this technical scheme exists two defects, one is the long-time high-speed friction nozzle of sand, and nozzle easily damages, in addition, if when needing thickness two kinds of abrasive materials to use simultaneously, then can only artificial batch mixing in advance, and labour intensity is large.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of long service life and evenly can spray the sand blasting unit of thickness two kinds of abrasive materials.
The technical solution of the utility model is:
A kind of sand blasting unit of improvement, comprise air compressor, connect the air jet pipe of air compressor, be arranged on the Jin Sha mechanism on air jet pipe, it is characterized in that, described Jin Sha mechanism comprises the first sand-feeding tube, be arranged on first on the first sand-feeding tube and enter sand valve, second sand-feeding tube, be arranged on second on the second sand-feeding tube and enter sand valve, go out sandpipe, the first described sand-feeding tube and the discharge end of the second sand-feeding tube are all communicated to out sandpipe, its effect is the forward slip value that thickness abrasive material can shaked out, reduce hand labor intensity, go out sandpipe and penetrate inner side from the outside of air jet pipe,
Described air jet pipe outlet side is provided with rifle head, described rifle head comprises outer tube, interior pipe and breathable membrane, outer tube coordinates with air jet pipe and is communicated with, interior pipe arrange within the outer tube and with go out sandpipe and coordinate and be communicated with, described breathable membrane arranges ring-type between the inner and outer pipe sections to breathe freely hard plate, and its effect ensures that sand can not pour in down a chimney into air jet pipe and internally pipe is played a supporting role;
The shaking out of the outlet side end face of the outer tube of described rifle head and interior pipe holds end face distance to be greater than 1 millimeter and interior pipe does not stretch out outside outer tube, its effect makes the interior pipe of rifle head because the raw negative pressure of the high-speed air flow movable property of outer tube, sand is siphoned away by negative pressure and sprays along with high-speed air, because this device is the thrust utilizing negative pressure to produce, less than the thrust directly produced by compressed air, so the speed that abrasive material advances wants slow, this significantly reduces the wearing and tearing of abrasive material to equipment, and equipment life is extended greatly.
Further, described air compressor is by the first soft pipe connection air jet pipe and the first flexible pipe and air jet pipe junction are provided with jet valve, the effect of flexible pipe makes air compressor can be placed on optional position and is not subject to the impact of sand blasting unit, and jet valve then can control jet.
Further, the outer tube of described air jet pipe and rifle head is by the second soft pipe connection, the described interior pipe going out sandpipe and rifle head is by the 3rd soft pipe connection, and the 3rd described flexible pipe is positioned at the second flexible pipe, and its effect makes the flexibly more convenient to operate of rifle head by soft pipe connection.
Further, described rifle head can arrange handle, convenient operation.
The beneficial effects of the utility model are: the utility model is rational in infrastructure, by the setting of outer tube and interior pipe, the high velocity air of outer tube is made to allow interior pipe produce very large negative pressure, because this device is the thrust utilizing negative pressure to produce, less than the thrust directly produced by compressed air, so the speed that abrasive material advances wants slow, this significantly reduces the wearing and tearing of abrasive material to equipment, and equipment life is extended greatly; In addition, if when needing thickness two kinds of abrasive materials to use simultaneously, do not need artificial batch mixing in advance, labour intensity reduces.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-jet valve, 2-first flexible pipe, 3-air compressor, 4-go out sandpipe, 5-air jet pipe, 6-the 3rd flexible pipe, 7-second flexible pipe, pipe in 8-, 9-breathable membrane, 10-first enter sand valve, 11-first sand-feeding tube, 12-second enter sand valve, 13-outer tube, 14-second sand-feeding tube.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
As shown in Figure 1, a kind of sand blasting unit of improvement, comprises air compressor 3, the air jet pipe 5 connecting air compressor 3, the Jin Sha mechanism be arranged on air jet pipe 5.Jin Sha mechanism can by the sand pond in the soft pipe connection external world or sand tank.But do not need power-equipment, because the utility model itself has the ability of inhaling sand.
