Abstract
Description
Technical Field
[0001] This utility model belongs to the field of gypsum packaging technology, specifically relating to a dust removal and packaging device for hemihydrate gypsum. Background Technology
[0002] Hemihydrate gypsum powder easily generates a large amount of dust during the ton bag filling process. Existing packaging equipment usually uses a single negative pressure dust suction port for dust removal, but there are obvious defects. During the packaging process, in addition to the bag opening, dust will also escape outward from the gaps in the side walls of the ton bag due to the leakage of internal airflow. Currently, the method of adsorbing dust by negative pressure at a single location at the bag opening is not effective in adsorbing dust that escapes from the side walls of the ton bag over a large area. Some dust falls or escapes. Moreover, the dust adsorbed by negative pressure is easily drawn towards the bag opening by the negative pressure airflow and comes into contact with the complex structural surfaces and pipelines of the equipment at the bag opening. It will adhere to the complex structural surfaces and pipeline surfaces and is difficult to clean. Utility Model Content
[0003] This utility model provides a dust removal and packaging device for hemihydrate gypsum, which can adsorb dust that escapes during the packaging process of ton bags from multiple positions and in all directions, preventing dust from escaping into the external space and preventing dust from adhering to the complex surface of the equipment structure when it is driven by negative pressure airflow.
[0004] This utility model provides the following technical solution: a dust removal and packaging device for hemihydrate gypsum, comprising a packaging mechanism body, a filling pipe and a filling port negative pressure sleeve, wherein a U-shaped dust interception plate is fixedly connected to the inner wall of the packaging mechanism body, a dust adsorption trough plate is fixedly connected to the bottom end of the U-shaped dust interception plate, a corrugated dust collection plate is fixedly connected to the inner wall of the packaging mechanism body, a plurality of dust collection ports are opened at the top of the concave edge of the corrugated dust collection plate, a dust collection chamber is fixedly connected to the bottom end of the corrugated dust collection plate, and a side baffle is fixedly connected to the side wall of the packaging mechanism body.
[0005] The corrugated dust collection plate has several cone blocks fixedly connected to the top of its concave edge, and the cone blocks are staggered with the dust collection port.
[0006] The corrugated dust collection plate has a support frame fixedly connected to the bottom of the protruding edge, and the support frame is fixedly connected to the main body of the packaging mechanism.
[0007] The packaging mechanism body has a negative pressure connecting pipe on one side.
[0008] The upper suction pipe is fixedly connected to the top side wall of the negative pressure connecting pipe, and the upper suction pipe is fixedly connected to the negative pressure sleeve of the filling port. A control valve is installed on the upper suction pipe.
[0009] The negative pressure connecting pipe is fixedly connected to a central suction pipe on its side wall, and the central suction pipe is fixedly connected to the floating dust adsorption tank plate.
[0010] The negative pressure connecting pipe is fixedly connected to the side wall of the lower suction pipe, and the lower suction pipe is fixedly connected to the dust collection chamber.
[0011] The beneficial effects of this utility model are as follows: the C-shaped dust interception plate intercepts the floating dust overflowing from the gaps in the side wall of the ton bag, and the dust is absorbed by the dust adsorption tank plate. This can prevent the floating dust overflowing from the gaps in the side wall of the ton bag from escaping and adhering to the surface of the upper components and cables. In conjunction with the corrugated dust collection plate, dust collection port and dust collection chamber, it can collect the falling dust overflowing from the gaps in the side wall of the ton bag. In addition, the negative pressure sleeve of the filling port adsorbs the dust escaping from the bag opening.

[0019] Please see Figures 1-5The present invention provides the following technical solution: a dust removal and packaging device for hemihydrate gypsum, comprising a packaging mechanism body 1, a filling pipe 11 and a filling port negative pressure sleeve 2, a U-shaped dust interception plate 3 fixedly connected to the inner wall of the packaging mechanism body 1, a dust adsorption groove plate 31 fixedly connected to the bottom end of the U-shaped dust interception plate 3, a corrugated dust collection plate 4 fixedly connected to the inner wall of the packaging mechanism body 1, a plurality of dust collection ports 41 opened at the top of the concave edge of the corrugated dust collection plate 4, a dust collection chamber 42 fixedly connected to the bottom end of the corrugated dust collection plate 4, and a side baffle 5 fixedly connected to the side wall of the packaging mechanism body 1.
[0020] In this implementation plan: Following the existing usage procedure of the packaging mechanism body 1, the worker suspends the lifting strap of the ton bag on the hook and wraps the bag opening around the outside of the filling port negative pressure sleeve 2. The clamping mechanism on the packaging mechanism body 1 presses the bag opening against the outer wall of the filling port negative pressure sleeve 2. The feeding mechanism of the packaging mechanism body 1 then fills the ton bag with hemihydrate gypsum powder through the filling pipe 11. The negative pressure connecting pipe 6 is connected to the external negative pressure mechanism's pipes. The upper suction pipe 61, middle suction pipe 62, and lower suction pipe 63 respectively provide negative pressure adsorption and dust removal to the filling port negative pressure sleeve 2, the floating dust adsorption tank plate 31, and the dust collection chamber 42. During the filling process, when the controller of the packaging mechanism 1 starts the feeding mechanism, it simultaneously controls the control valve 611 to reduce the flow rate of the upper suction pipe 61. This low-flow-rate suction removes dust drifting from inside the ton bag towards the bag opening. This method of suction from inside the bag opening prevents dust from escaping through gaps and improves the suction effect. By reducing the flow rate, a suitable suction force is provided, preventing excessive suction from directly drawing dust into the filling port negative pressure sleeve 2. Furthermore, the filling pipe 11 extends beyond the end of the filling port negative pressure sleeve 2, maintaining a distance between the suction port of the filling port negative pressure sleeve 2 and the dust drop location, further preventing dust from being drawn into the filling port negative pressure sleeve 2. Dust falling into the ton bag from the filling tube 11 is directly absorbed into the negative pressure sleeve 2 at the filling port. When the hemihydrate gypsum is poured into the ton bag, the gas inside the ton bag is compressed and escapes outward from the gaps in the side wall of the ton bag. Some dust floats upward, and the rest floats downward. The floating dust overflowing from the gaps in the side wall of the ton bag is intercepted by the C-shaped dust interception plate 3, and the dust is absorbed by the dust adsorption tank plate 31. This can prevent the floating dust overflowing from the gaps in the side wall of the ton bag from escaping and adhering to the surface of the upper components and cables. The dust intercepted by the C-shaped dust interception plate 3 adheres to the C-shaped dust interception plate 3 or the side baffle 5. The C-shaped dust interception plate 3 and the side baffle 5... The surface of plate 5 is simple and flat, making it easy to wipe and clean. The corrugated dust collection plate 4, dust collection port 41, and dust collection chamber 42 can collect the falling dust that overflows from the gaps in the side wall of the ton bag. By adsorbing the dust that escapes during the ton bag packaging process from multiple positions and in all directions, it prevents the dust from escaping into the external space and also prevents the dust from adhering to the complex surface of the equipment structure when it is driven by the negative pressure airflow. When the controller controls the clamping mechanism to release the clamping of the ton bag, the controller controls the control valve 611 to restore the normal flow rate and increase the negative pressure suction at the filling port negative pressure sleeve 2 to prevent the dust that is shaken by the bag opening from escaping outward.
[0021] Several cones 43 are fixedly connected to the top of the concave edge of the corrugated dust collection plate 4. The cones 43 are staggered with the dust collection port 41. By setting the cones 43, the falling dust can be guided, making it easier for the dust to enter the dust collection port 41.
[0022] A support frame 44 is fixedly connected to the bottom of the protruding edge of the corrugated dust collection plate 4. The support frame 44 is fixedly connected to the main body 1 of the packaging mechanism. By setting the support frame 44, the corrugated dust collection plate 4 can be supported to support the ton bag and the operator.
[0023] A negative pressure connecting pipe 6 is provided on one side of the packaging mechanism body 1; by setting the negative pressure connecting pipe 6, the pipe of the negative pressure mechanism can be connected to provide negative pressure suction.
[0024] The upper suction pipe 61 is fixedly connected to the top side wall of the negative pressure connecting pipe 6. The upper suction pipe 61 is fixedly connected to the filling port negative pressure sleeve 2. A control valve 611 is installed on the upper suction pipe 61. The upper suction pipe 61 can provide negative pressure suction to the filling port negative pressure sleeve 2.
[0025] A central suction pipe 62 is fixedly connected to the side wall of the negative pressure connecting pipe 6, and the central suction pipe 62 is fixedly connected to the floating dust adsorption tank plate 31; the central suction pipe 62 can provide negative pressure suction to the floating dust adsorption tank plate 31.
[0026] A lower suction pipe 63 is fixedly connected to the side wall of the negative pressure connecting pipe 6, and the lower suction pipe 63 is fixedly connected to the dust collection chamber 42; the lower suction pipe 63 can provide negative pressure suction to the dust collection chamber 42.
[0027] The working principle and usage process of this utility model are as follows: Following the usage process of the packaging mechanism body 1 in the prior art, the operator suspends the lifting strap of the ton bag on the hook and wraps the bag opening around the outside of the filling port negative pressure sleeve 2. The clamping mechanism on the packaging mechanism body 1 presses the bag opening against the outer wall of the filling port negative pressure sleeve 2. The feeding mechanism of the packaging mechanism body 1 then fills the ton bag with hemihydrate gypsum powder through the filling pipe 11. The negative pressure connecting pipe 6 is connected to the pipe of the external negative pressure mechanism. The upper dust suction pipe 61, middle dust suction pipe 62, and lower dust suction pipe 63 provide negative pressure adsorption and dust removal to the filling port negative pressure sleeve 2, the floating dust adsorption tank plate 31, and the dust collection chamber 42, respectively. During the filling process, when the controller of the packaging mechanism body 1 starts the feeding mechanism, it synchronously controls the... Valve 611 reduces the flow rate of the upper suction pipe 61, using a low flow rate to adsorb dust drifting from inside the ton bag towards the bag opening. When hemihydrate gypsum is poured into the ton bag, the gas inside the ton bag is squeezed and escapes outward from the gaps in the side wall of the ton bag. Some dust drifts upward, and the rest drifts downward. The floating dust overflowing from the gaps in the side wall of the ton bag is intercepted by the C-shaped dust interception plate 3, and the dust is absorbed by the dust adsorption tank plate 31. The corrugated dust collection plate 4, dust collection port 41, and dust collection chamber 42 collect the falling dust overflowing from the gaps in the side wall of the ton bag. By adsorbing the dust that escapes during the ton bag packaging process from multiple positions and in all directions, the dust is prevented from escaping into the external space and from adhering to the complex structural surface above the equipment during the process of being driven by negative pressure airflow.
