The number of the columns is not limited to three, but may be four, five, etc. in other embodiments, and is not particularly limited herein, and may be according to actual situations.

The spray cleaning mechanism 1 comprises an annular body 11 and a liquid delivery assembly 12. In the present embodiment, the annular body 11 of the annular shape has a hollow portion so that the annular body 11 can communicate with the outlet of the powder processing mechanism 4 through the hollow portion. In other embodiments, the shape of the annular body 11 may be rectangular or polygonal, and is not specifically limited herein according to practical situations. The purpose of arranging the annular body 11 in an annular shape in the present application is to: the annular body 11 in the annular shape has no dead angle, so that powder is not remained in the dead angle, and the collection rate of the powder is further ensured.

And, the annular body 11 has a cavity 111 and a plurality of nozzles disposed on an inner wall of the annular body 11 and communicating with the cavity 111, and the liquid delivery assembly 12 communicates with the cavity 111 to deliver liquid to the cavity 111 to be sprayed from the nozzles 112 into the annular body 11. Therefore, in the process that the liquid conveying component 12 needs to convey the liquid to the annular body 11, the annular body 11 does not obstruct the conveying of the liquid, and the collection rate of the powder is further improved.

The liquid delivery assembly 12 includes a water tank 121 provided on one side of the annular body 11, a pump body provided on one side of the water tank 121, a first delivery pipe communicating the pump body with the water tank 121, and a second delivery pipe communicating the pump body with the cavity 111. In the present embodiment, the dust removing apparatus 100 further includes an auxiliary plate, which is connected to the pressing mechanism 2, on which the water tank 121 and the pump body are placed. In other embodiments, the auxiliary board may be connected to the supporting frame 41, which is not limited herein, and may be determined according to practical situations. Also, in this embodiment, the liquid stored in the water tank 121 is water. In other embodiments, the liquid stored in the water tank 121 may be set according to actual conditions.

Wherein the nozzle 112 has a spray mode and a water spray mode to switch between the spray mode and the water spray mode. When in a spraying mode, the liquid in the water tank 121 is conveyed to the nozzle 112 through the first conveying pipe, the pump body and the second conveying pipe, and sprayed out after being atomized through the spraying mode of the nozzle 112 so as to wet the powder, so that the powder sinks under the action of the self weight of the powder; when in the water spraying mode, the liquid in the water tank 121 is conveyed to the nozzle 112 through the first conveying pipe, the pump body and the second conveying pipe, and is sprayed out after passing through the water spraying mode of the nozzle 112, so that the cleaning liquid is conveyed into the tank of the extrusion mechanism 2 until the liquid level in the tank reaches a preset value. In the present embodiment, the spraying mode and the water spraying mode of the nozzle 112 can be achieved by adjusting the structure of the nozzle 112, for example, by controlling the distance between the spray core and the outer structure of the nozzle 112, and the spraying mode of the nozzle 112 or the water spraying mode of the nozzle 112 can be adjusted. The structure of the nozzle 112 is a conventional structure, and the adjustment mode of the nozzle 112 is also conventional, which is not described herein.

The pressing mechanism 2 includes a case 23 having a receiving groove 231, a pressing member 24 provided in the case 23 to partition the receiving groove 231 into at least two pressing chambers, and a pressing assembly movable relative to the pressing member 24 to press-mold a target object in the pressing chambers. After the wetted powder is sunk from the outlet of the annular body 11 into the receiving groove 231 of the case 23, the pressing assembly moves relative to the partition 24 to press the powder in the pressing chamber into a block and shape. In the present embodiment, the purpose of providing the separator 24 is to: the divider 24 may define the position of the partial compression assembly and prevent positional misalignment during movement of the partial compression assembly. And the volume of the powder block after extrusion molding is smaller, so that the powder block is convenient to take out and clean.

In the present embodiment, the partition 24 is provided with three, i.e., partitions the receiving groove 231 into four pressing chambers. In other embodiments, the number of the spacers 24 may be set according to the size of the accommodating groove 231, for example, the spacers 24 may be provided with two, four, etc., which are not limited herein, and may be determined according to practical situations.

The pressing assembly includes a pressing member 25 and a pressing body 21 connected to the pressing member 25 to drive the pressing member 25 to move. In the present embodiment, the pressing body 21 may be a linear motor, an air cylinder, an electric telescopic rod, or the like, and may be driven linearly. Wherein the pressing member 25 has at least two sliding grooves slidably fitted with at least two partitioning members 24, respectively. Accordingly, the pressing body 21 drives the pressing member 25 to slide with respect to the partitioning member 24 through the slide groove. As is clear from the above, the number of the sliding grooves is also three because three partitions 24 are provided.

The pressing member 25 includes a push rod 251 disposed in a first direction (indicated by an arrow b in the drawing) and a pressing body 252 disposed in a second direction (indicated by an arrow c in the drawing) and connected to the push rod 251, the first direction being perpendicular to the second direction and the first direction being parallel to the longitudinal direction of the partitioning member 24, the pressing body 21 being connected to the push rod 251, the pressing body 21 driving the push rod 251 to move to drive the pressing member 25 to move. Wherein the extrusion 25 has an extrusion face. The height of the pressing surface is close to or equal to the height of the case 23, and can be set according to practical conditions.

The extrusion mechanism 2 further comprises a drawing plate 22, the drawing plate 22 is arranged at the bottom of the accommodating groove 23, and the bottom end of the partition piece 24 is in contact with the surface of the drawing plate 22, so that powder in two adjacent extrusion cavities is prevented from flowing mutually, and the collection rate of the powder is improved. The drawer 22 is movable relative to the housing 23 to switch between a first position and a second position; when in the first position, the drawer plate 22 opens the accommodating groove 231 to be communicated with the outside; when in the second position, the drawer plate 22 closes the accommodating groove 231 to be isolated from the outside.

The purging mechanism 5 comprises an air pump 51, an air duct 52 connecting the air pump 51 with the box 23 and a one-way valve arranged on the air duct 52, and the one-way valve is arranged to prevent the liquid in the box 23 from flowing backwards to the air pump 51, thereby influencing the operation and performance of the air pump 51.

The dust removing apparatus of the present application further includes a detection mechanism disposed in the housing 23, the adjustment of the spray mode and the water spray mode of the nozzle 112 is performed based on the detection result of the detection mechanism, and the opening and closing of the purge mechanism 5 may be performed based on the detection result of the detection mechanism.

Specifically, the detection mechanism includes a first detection member disposed on the case 23, and the first detection member is adapted to detect whether the liquid level in the accommodating groove reaches a preset value. As can be seen from the foregoing, when the nozzle 112 is in the water spray mode, the cleaning liquid is supplied into the tank 23 to clean the tank 23. The cleaning process may be performed in coordination with the movement of the press body of the press mechanism 2.

The water spray mode or the spray mode of the nozzle 112 is started by whether dust falls from the outlet of the dust processing mechanism 4. Accordingly, the dust removing apparatus further includes a detection assembly provided at the outlet of the dust processing mechanism 4, the detection assembly being adapted to detect whether dust falls at the outlet of the dust processing mechanism 4, and the nozzle 112 switches the spray mode or the water spray mode depending on the detection result of the detection assembly. For example, when dust falls at the outlet of the dust handling mechanism 4, the nozzle 112 is in spray mode so that the dust becomes wet until it falls into the tank 23. When no dust falls at the outlet of the dust processing means 4, the nozzle 112 switches the mode to the water spray mode to deliver the cleaning liquid into the tank 23. It is noted that the switching of the nozzle 112 mode is actually also based on the action of the drawer 22. After no dust falls at the outlet of the dust processing mechanism 4 and the drawing plate 22 has been opened and closed in practice (i.e., the briquetted powder lump is removed from the case 23), the nozzle 112 feeds the cleaning liquid into the case 23. In this embodiment, the detection component is an infrared sensor or a photoelectric sensor. Wherein the closing of the drawer 22 may be detected based on proximity switches mounted on the drawer 22 and/or the housing 23. It should be noted that, after the accommodating groove is closed by the drawing plate 22, no gap is left between the drawing plate 22 and the box 23, i.e. a sealing ring is arranged between the drawing plate 22 and the box 23, so as to prevent the solid liquid in the accommodating groove from flowing out from the gap between the drawing plate 22 and the box 23.

When the drawing plate 22 is opened and closed once, it indicates that the powder block pressed into the block 23 has been moved out of the block 23, and at this time, the block 23 can be cleaned, thereby supplying cleaning liquid into the block 23. And stopping the delivery of the cleaning liquid is based on the liquid level detected by the first detecting member. When the first detection part detects that the liquid level reaches a preset value, the pump body stops running. The press body moves again to match the cleaning in the tank 23. In this embodiment, the first detecting member is a liquid level sensor, so that the liquid level in the tank 23 can be detected better.

The detection mechanism further comprises a second detection member arranged on the drawer plate 22, which is adapted to detect whether liquid is still present in the receiving tank. In this embodiment, the second detecting member is a weight sensor for detecting the weight to determine whether the liquid is still present in the accommodating groove. If there is liquid in the containing groove, the weight sensor can detect the weight applied by the liquid. If there is no liquid in the accommodating groove or liquid exists in the corner, the liquid is ignored. The range of the detection value of the weight sensor depends on the actual situation, that is, the weight of the liquid in the tank 23 applied to the weight sensor may be set according to the actual situation, and the embodiment is not particularly limited.

The air pump 51 is turned on and off according to the detection result of the second detecting member. When the second detecting member detects that there is no liquid or a small amount of liquid in the accommodating groove, the air pump 51 is started to deliver air into the accommodating groove so as to blow the accommodating groove to dry. In order to further ensure the drying efficiency, the box 23 may be further provided with a ptc heater, which can increase the temperature in the box 23, thereby achieving the effect of further improving the drying efficiency.

The dust removing apparatus 100 of the present application is implemented as follows: after the powder processing in the powder processing mechanism 4 is completed and the finished powder is conveyed out, a large amount of powder remains. The remaining powder is deposited from the outlet of the powder processing mechanism 4 into the spray cleaning mechanism. The pump body of the spray cleaning mechanism is kept open so that water in the water tank 121 can be delivered to the cavity 111 and sprayed out from the liquid spraying port 112 to wet the settled powder. The wetted powder falls into the receiving groove 23 under the action of its own weight, and the fallen wetted powder is separated into different extrusion chambers by the separation plate. At this time, the pressing body 21 is activated so that the pressing body 21 drives the push rod 251 to move to drive the pressing member 25 to move until a large amount of the wetted powder is pressed into a block. An external force is applied to switch the drawing plate 22 from the second position to the first position, so that the bottom of the case 23 is opened, and the powder mass extruded into a mass is output. After the powder lump is removed out of the accommodating groove 231, the powder is not detected at the outlet of the powder processing mechanism, and the nozzle 112 is switched from the spraying mode to the water spraying mode so as to convey the cleaning liquid into the tank 23. When the liquid level of the cleaning liquid in the tank 23 reaches the first detection member (i.e., reaches a preset value), the pump body is closed to stop the feeding of the cleaning liquid into the tank 23. The press body is started again to clean the inside of the box body. When the cleaning is completed, the suction plate 22 is opened again to drain the liquid outward. After the weight value detected by the second detecting piece is out of the preset range, the purging mechanism 5 is started, and the air pump conveys air into the box body through the air guide pipe so as to blow the box body dry.

To sum up: by the aid of the squeezing mechanism, the spray cleaning mechanism, the blowing mechanism and the detection mechanism, mist can be formed by the spray cleaning mechanism, dust falling from an outlet of the dust processing mechanism is wetted, and the wetted powder can enter the squeezing mechanism under the action of self gravity; the extrusion mechanism performs extrusion treatment on the wetted powder to compact the powder in time, so that the powder is prevented from flying into a human body, and meanwhile, the collection rate of the powder is improved; after the powder blocks in the extrusion mechanism are removed outside the extrusion mechanism, the spray cleaning mechanism conveys cleaning liquid into the extrusion mechanism to clean the extrusion mechanism, and after the cleaning is finished, the purging mechanism can comprehensively clean the extrusion mechanism, so that the cleaning efficiency of powder in the extrusion mechanism is ensured.

The foregoing is merely one specific embodiment of the application, and any modifications made in light of the above teachings are intended to fall within the scope of the application.
