When the corresponding cylinder body is subjected to a filling process, the control system controls the sand outlet valve in the cylinder body to be closed, at the moment, the cylinder body forms a closed cavity, and abrasive materials can enter the cylinder body through the feeding channel.
Because the abrasive grains are small, the abrasive grains have high friction force, and even under the extrusion action of compressed air, the abrasive grains cannot uniformly move in the discharge channel. To this, all be equipped with the screw conveyor 62 that is used for pushing out the abrasive material in first discharging channel 6 and the second discharging channel 7 in this embodiment, can evenly will fall into discharging channel's abrasive material through screw conveyor 62 and impel forward, make the even blowout of abrasive material, avoid appearing the condition that the interval spouts the material, the working effect is better.
At the same time, the first and second flow channels 6, 7 merge to form a main pipe 72, which main pipe 72 is used for connecting to the sand blasting lance 40. Through this setting, join the discharging channel of two cylinder bodies, directly connect through a sand blasting gun 40 and just can realize the sandblast to the work piece, saved the cost (all set up sand blasting gun 40 with two discharging channel) and also improved work efficiency simultaneously (need not change discharging channel's sand blasting gun 40 when two cylinder bodies spout the material flow in turn).
Preferably, the main air inlet pipe 33 is connected with the main discharge pipe 72 through a sand discharge pipe, and the sand discharge pipe is provided with a sand discharge valve 73 for controlling the on-off of the sand discharge pipe. Since a part of the abrasive remains in the main tapping pipe 72 after the completion of the blasting operation of the workpiece, the recovery of the apparatus is not facilitated. In contrast, after the sand blasting operation is finished, the sand discharge valve 73 can be controlled to be opened, the main inlet pipe 33 is communicated with the main outlet pipe 72, and the compressed gas can spray the abrasive in the main outlet pipe 72 from the sand blasting gun 40, so as to ensure that the abrasive is not accumulated in the main outlet pipe 72.

The V-shaped notch and the metal valve seat have a shearing effect, and are particularly suitable for media containing fibers, tiny solid particles, slurry and the like. The scheme is realized by opening and closing a pneumatic control valve. In this embodiment, two cylinders perform different processes simultaneously, that is, when one type of valve (sand inlet valve, vacuum valve, and sand outlet valve) in one cylinder is opened, the other cylinder will close the same type of valve, for example: when the first cylinder 1 is in the sand blasting process, the first sand outlet valve 61 is opened, and when the second cylinder 2 is in the filling process, the second sand outlet valve 71 is closed. Therefore, in the embodiment, besides the control system, the opening and closing of the same type of switches of the two cylinders can be controlled through linkage control of a mechanical structure.
According to the scheme, whether the switching of the two cylinder body processes is executed or not is judged according to the stock of the abrasive materials in the cylinder body, the cylinder body is usually kept in a sealed state in the working process, and workers cannot visually know the stock of the abrasive materials in the cylinder body. In this regard, in the present embodiment, detectors for detecting the height of the abrasive deposited in the cylinder are provided in both the first cylinder 1 and the second cylinder 2, and the detectors include a lower limit detector 82 provided at the bottom of the cylinder and an upper limit detector 81 provided at the upper part of the cylinder. The lower limit detector 82 is used for detecting that the corresponding cylinder body sprays the material, and if the abrasive material consumption in the cylinder body reaches the height position of the lower limit detector 82, the material spraying flow of the cylinder body is stopped at the moment, the cylinder body is converted into a filling flow, and the cylinder body is switched to another cylinder body for spraying the material; the same upper limit detector 81 is used to detect that the corresponding cylinder body is filling, and if the abrasive material accumulation in the cylinder reaches the height position of the upper limit detector 81, the filling process of the cylinder body is stopped at this time, and the next switching of the material spraying process is waited (normally, the filling speed of the filling process is greater than the material spraying speed, and the alternate circulation of the two cylinder bodies can be satisfied).

The rotation-resisting material level switch uses a micro motor as a driving device, a transmission shaft is connected with a clutch, when the motor does not contact with the material, the motor operates normally, and when blades contact with the material, the motor stops rotating. By the principle, the condition that the output contact point signal of the lower limit detector 82 is set to be that the abrasive does not block the blade, the motor can start to operate, and at the moment, the material spraying flow of the cylinder is stopped; the upper limit detector 81 outputs a contact signal when the abrasive material blocks the blade and the motor stops rotating, thereby stopping the filling process of the cylinder.
Similarly, since the abrasive particles themselves are small and have a large friction force with each other, the abrasive particles cannot uniformly fall into the discharge passage from the cylinder even under the squeezing action of the compressed air. To this end, all still be equipped with in first cylinder body 1 and the second cylinder body 2 and make things convenient for the inside abrasive material of cylinder body to get into discharge channel's agitating unit 9 separately, agitating unit 9 includes pivot, a plurality of puddler and a plurality of chain, and a plurality of puddlers set firmly in the pivot and follow the circumference interval distribution of pivot, the one end of chain set firmly in on the free end of puddler, the other end set firmly in the pivot and lie in the puddler below.
