Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a packaging device for concrete water reducer. Background Art

[0002] A water reducer is a concrete admixture that can reduce the mixing water consumption under the condition of maintaining the basic unchanged slump of concrete. After the water reducer is dried, it needs to be packed and stored by equipment. Patent 202410267275.5 discloses a canned device for packaging water reducer, which forms a closed space by adding a dust-proof cloth during the feeding process to avoid the powder flying and polluting the environment. However, the flying powder will adhere to the dust-proof cloth and scatter again during the stretching process of the dust-proof cloth, resulting in poor dust removal effect. The dust removal effect during the packing process needs to be further improved. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a packaging device for concrete water reducer.

[0004] The purpose of the utility model is realized by the following technical solutions: A packaging device for concrete water reducer, including a frame, a roller conveyor belt, and a screw feeder. The frame is in an inverted L shape. The roller conveyor belt is located below the head of the frame. The screw feeder is fixedly connected to the frame. There are a cylinder, a cover plate, a first corrugated pipe, and a second corrugated pipe arranged on the frame. The cylinder is vertically suspended downward on the frame. The cover plate is horizontally fixedly connected to the output end of the cylinder. There are an air inlet and a dust suction port arranged on the cover plate. A one-way valve allowing gas to transmit downward is arranged at the air inlet. One end of the first corrugated pipe is communicated with the discharge port of the screw feeder, and the other end of the first corrugated pipe passes through the cover plate. One end of the second corrugated pipe is communicated with the dust suction port, and the other end of the second corrugated pipe is communicated with an external negative pressure interface.

[0005] Further, a dust filter cartridge and a suction fan are arranged on the frame. The air inlet end of the dust filter cartridge is communicated with the second corrugated pipe, and the air outlet end of the dust filter cartridge is communicated with the suction fan.

[0006] Further, there are a limit screw, a retaining piece, a spring, and a buffer ring arranged on the cover plate. One end of the limit screw is vertically fixedly connected to the upper surface of the cover plate. The retaining piece is rotationally fixedly connected to the top of the limit screw by threads. The spring and the buffer ring are sleeved on the limit screw from top to bottom in sequence. The spring and the buffer ring are located between the retaining piece and the cover plate.

[0007] Further, a sealing ring is arranged on the buffer ring, and the sealing ring is fixedly connected to the lower surface of the buffer ring.

[0008] The utility model has the following advantages: the cover plate is covered on the packaging barrel by a cylinder to form a closed space, avoiding the scattering of dust during the feeding process of the powder material. With the one-way valve and the dust suction port arranged on the cover plate, the powder material suspended in the closed space can be extracted, avoiding the problem of secondary dust pollution after opening the cover and improving the packaging dust removal effect; the setting of the spring and the buffer ring can avoid the damage problem caused by the direct extrusion of the cover plate on the packaging barrel and improve the application range for packaging barrels of different specifications and heights.

[0014] As Figure 1As shown in the figure, a concrete water reducer packaging device includes a frame 1, a roller conveyor belt 2, and a screw feeder 4. The lower part of the frame 1 is a control cabinet, and the upper part of the frame 1 is a double-layer support frame. The double-layer support frame extends forward compared to the control cabinet, and the two together form an inverted L shape. The roller conveyor belt 2 is located below the double-layer support frame at the head of the frame 1. The roller conveyor belt 2 consists of multiple conveying rollers. The screw feeder 4 is fixedly connected to the frame 1. The screw feeder 4 and the roller conveyor belt 2 can be directly purchased on the market. Two cylinders 6, a cover plate 7, a first corrugated pipe 5, a second corrugated pipe 10, a dust filter cartridge 12, a suction fan 11, multiple limit screws 14, a retaining plate 15, a spring 16, and a buffer ring 13 are installed on the frame 1. The sleeve end of the cylinder 6 is fixedly connected between the double-layer support frames. The output end of the cylinder 6 extends vertically downward. The cover plate 7 is horizontally fixedly connected to the output end of the cylinder 6 by bolts. An air inlet and a dust suction port 9 are provided in the middle of the cover plate 7. A one-way valve 8 that allows gas to flow downward is installed at the air inlet. One end of the first corrugated pipe 5 is connected to the discharge port of the screw feeder 4, and the other end of the first corrugated pipe 5 passes through the cover plate 7 to discharge materials downward. One end of the second corrugated pipe 10 is connected to the dust suction port 9, and the other end of the second corrugated pipe 10 is connected to the air inlet end of the external dust filter cartridge 12. The air outlet end of the dust filter cartridge 12 is connected to the suction fan 11. The bottom ends of multiple limit screws 14 are vertically welded to the upper surface of the cover plate 7. The limit screws 14 are arranged at intervals around the circular cover plate 7. The retaining plate 15 is provided with threaded holes, and the retaining plate 15 is rotatably fixedly connected to the top ends of the limit screws 14 by threads. The cover plate 7 is a cylindrical structure. The buffer ring 13 is sleeved on the cover plate 7, and the buffer ring 13 is concentric with the cover plate 7. The spring 16 and the buffer ring 13 are sleeved on the limit screws 14 from top to bottom in sequence. The buffer ring 13 can slide up and down along the limit screws 14. The spring 16 and the buffer ring 13 are located between the retaining plate 15 and the cover plate 7. A sealing ring 17 is installed on the buffer ring 13, and the sealing ring 17 is bonded to the lower surface of the buffer ring 13. The diameter of the sealing ring 17 is equal to the diameter of the packaging barrel 3.

[0015] The working principle of the present utility model: Start the cylinder. The output end of the cylinder drives the cover plate to move downward until the cover plate seals the packaging barrel. Start the screw feeder to feed materials into the packaging barrel. After the feeding is completed, turn off the screw feeder. Since the powder scatters after hitting the packaging barrel, start the fan, and use negative pressure to suck the floating powder into the dust filter cartridge or other dust collection devices. Finally, the cylinder resets to lift the cover plate, completing the function of quickly collecting the floating powder and avoiding the secondary overflow of the scattered powder from the packaging barrel after packaging. Since there are differences in the heights of actual packaging barrels, directly using the cylinder to directly cover the cover plate on the packaging barrel will cause problems of extrusion damage. A buffer ring is provided outside the cover plate. Even if the cylinder moves too far, the outer wall of the packaging barrel can push up the buffer ring, avoiding the extrusion damage to the packaging barrel.

[0016] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
