Description

Sand blasting apparatus

Technical field

The utility model relates to a kind of sand blasting apparatus.

Background technology

Existing sand blasting apparatus, after every task is complete, all can residual water in sand suction pipe and the residue such as iron sand.And this residue easily causes device that the situation that sand suction pipe stops up occurs in the time working for the second time, once after sand suction pipe obstruction, not only cannot carry out work, it is very also trouble that cleaning is got up, and can cause serious impact to operating efficiency.

In addition, existing sand blasting apparatus, the blowing head of being located at device both sides is mostly the device of constant flow, in the time that device internal gas pressure is larger, the dynamics that iron sand splashes also rises thereupon; If cannot increase the flow of blowing head place current, iron sand just very easily flies out outside auto levelizer, even may cause accident, for example, be splashed in staff's eyes; And when device internal gas pressure hour, the dynamics that iron sand splashes, also along with reduction, if cannot reduce a flow for blowing head place current, just very likely impacts rust cleaning work.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of sand blasting apparatus, and it can prevent that sand suction pipe is blocked.

For solving the problems of the technologies described above, the technical solution of the utility model sand blasting apparatus is:

Comprise sand bucket 1, in sand bucket 1, be vertically arranged with at least one sand suction pipe 11; Sand suction pipe 11 is fixedly connected with cylinder 2, and cylinder 2, for driving sand suction pipe 11 to move up and down, is controlled the bottom entrance of sand suction pipe 11 and the bottom of sand bucket 1 and whether is close to; The top of sand bucket 1 connects drainpipe 13; The top of sand bucket 1 connects one end of water inlet pipe 14, and the other end of water inlet pipe 14 connects the water inlet 31 of water pump 3, and the delivery port 32 of water pump 3 connects the entrance of distributive pipe 16; The top outlet of sand suction pipe 11 connects the entrance of sandpipe 12, and the outlet that goes out sandpipe 12 connects blast room 4; The two ends of blast room 4 connect respectively receives sand cylinder 5, receives sand cylinder 5 and is provided with blowing 6; Two blowings 6 connect respectively two outlets of distributive pipe 16; Receive sand cylinder 5 for two and connect sand bucket 1 by sand-returning pipe 15 respectively.

Detailed description of the invention

As shown in Figures 1 to 4, the utility model sand blasting apparatus, comprises sand bucket 1, is vertically arranged with at least one sand suction pipe 11 in sand bucket 1; Top one side of sand bucket 1 connects drainpipe 13, and the top opposite side of sand bucket 1 connects water inlet pipe 14, and the height of drainpipe 13 is higher than the height of water inlet pipe 14; Sand bucket 1 connects one end of water inlet pipe 14, and the other end of water inlet pipe 14 connects the water inlet 31 of water pump 3; The delivery port 32 of water pump 3 connects the entrance of distributive pipe 16;

Sand suction pipe 11 is fixedly connected with cylinder 2, and cylinder 2 is for driving sand suction pipe 11 to move up and down; The top outlet of sand suction pipe 11 connects the entrance of sandpipe 12, and the outlet that goes out sandpipe 12 connects blast room 4;

The two ends of blast room 4 connect respectively receives sand cylinder 5, and the outer end of receiving sand cylinder 5 is provided with blowing 6; Two blowings 6 connect respectively two outlets of distributive pipe 16; Blowing 6 is used to form guiding current, and iron sand is concentrated on and received in sand cylinder 5;

In blowing 6, be provided with the flow-control piece 61 that can rotate, for controlling from current sizes for blowing 6 ejection; The front shape of flow-control piece 61 is truncated cone-shaped, when flow-control piece 61 interior when mobile in blowing 6 vertically, space size between the endoporus of flow-control piece 61 and blowing 6 can change, thereby the discharge that enters into blowing 6 from distributive pipe 16 is changed thereupon; In the time that needs increase discharge, flow-control piece 61 is outwards moved, in the time that needs reduce discharge, flow-control piece 61 is screwed toward in;

Receive sand cylinder 5 for two and connect sand bucket 1 by sand-returning pipe 15 respectively; Concentrate on the iron sand of receiving in sand cylinder 5 and flow back in sand bucket 1 through sand-returning pipe 15, without adding new iron sand, thereby iron sand can be recycled.

Water pump 3 also can replace with external gas source device, current is become to gas and carry out the operation of device.

Operation principle of the present utility model is as follows:

The most at the beginning, in the sand bucket 1 of sealing, be placed with iron sand and water, due to weight and the density of iron sand, therefore iron sand is all in lower floor, and water is in upper strata;

Before operation, the bottom of sand bucket 1 is close in the bottom of sand suction pipe 11; When operation, controlled on sand suction pipe 11 and moved by cylinder 2, now the iron sand of sand bucket 1 bottom and the bottom entrance of sand suction pipe 11 come in contact; Open water pump 3, water pump 3 is drawn into the water on sand bucket 1 top in water inlet pipe 14, current are through the water inlet 31 of water pump 3, flow out from the delivery port 32 of water pump 3 again, thereby by the water sucking-off in sand bucket 1, air pressure in sand bucket 1 is changed, and under the effect of draught head, iron sand enters out sandpipe 12 by sand suction pipe 11; Iron sand enters blast room 4 from going out sandpipe 12, and under the effect of the draught head producing at water pump 3, iron sand is flashed, thereby the wire in blast room 4 is carried out to rust cleaning work, and the iron rust of wire surface is polished off;

The water of 3 sucking-offs of water pump enters in distributive pipe 16 through the delivery port 32 of water pump 3, finally by the outlet of distributive pipe 16 from blowing 6 ejection; Iron sand is in the process for wire rust cleaning, because the effect of air-flow can be splashed everywhere, and the blowing 6 that is positioned at 4 both sides, blast room is by the effect of current, the iron sand flashing is concentrated on and receive in sand cylinder 5, can prevent that iron sand is splashed to sand blasting apparatus outside and causes accident;

After rust cleaning end-of-job, control sand suction pipe 11 move down by cylinder 2, the bottom of sand suction pipe 11 is close to the bottom of sand bucket 1 again; Make water pump 3 delay work about one minute, under the effect of the draught head producing at water pump 3, the water and the iron sand that remain in sand suction pipe 11 are drawn onto in blast room 4, thereby make the inside of sand suction pipe 11 keep clean state, the situation of sand suction pipe 11 can not occur to stop up while causing lower task due to the accumulation of this task residue; Because sand suction pipe 11 is close to the bottom of sand bucket 1, so postpone in the process of work at water pump 3, the iron sand not having in sand bucket 1 enters the phenomenon in sand suction pipe 11;

In the time of hypervolia in sand bucket 1, water can be discharged automatically from drainpipe 13, and the situation of sand bucket 1 spilling water can not occur.
