Abstract
Description
Technical Field
[0001] This utility model relates to the field of pre-made food material mixing, specifically a dust suppression device for pneumatically conveyed materials. Background Technology
[0002] In some pre-prepared food processing, such as pre-made kimchi, the addition of seasonings is typically done by spraying due to the large production volume. This involves spraying the seasoning additives into the pre-prepared food for contact and mixing, thus achieving the goal of adding seasonings in large quantities. However, the current machinery used for spraying seasonings into these pre-prepared foods often sprays the seasonings in a powdery form, which suspends in the air and cannot quickly settle onto the surface of the pre-prepared food. This increases the processing and mixing time and can even lead to waste of the seasonings. Utility Model Content
[0003] The objective of this utility model is achieved through the following technical solution:
[0004] A dust suppression device for pneumatic material conveying includes a material funnel for holding materials to be sprayed and mixed. A control valve is installed at the bottom of the material funnel to control the falling of the materials. A falling pipe for the materials to be sprayed and mixed is connected through the bottom of the material funnel. A discharge device for driving the materials to be sprayed and mixed through the falling pipe is installed in the falling pipe. A conveying pipe for conveying the materials to be sprayed and mixed is connected through the end of the falling pipe away from the material funnel. One end of the conveying pipe is connected to a high-pressure air pump, and the other end of the conveying pipe is detachably connected to a high-pressure nozzle structure for spraying the materials to be sprayed and mixed.
[0005] Preferably, a mixing water pipe is connected through the side wall of the falling pipe. One end of the mixing water pipe is connected to a water pump via a pipe, and the other end of the mixing water pipe extends into the falling pipe to mix the materials that need to be sprayed and mixed as they pass through the falling pipe.
[0006] Preferably, the outer wall of the material funnel is provided with a partition cavity;
[0007] The partition cavity is connected to the drop pipe at one end near the drop pipe.
[0008] The partition cavity and the upper part of the material funnel are provided with several holes.
[0009] Preferably, the high-pressure nozzle structure includes a high-pressure material nozzle;
[0010] The high-pressure material nozzle is detachably threaded to one end of the conveying pipe, and the other end of the high-pressure material nozzle is detachably threaded to the conveying pipe.
[0011] The beneficial effects of this utility model are as follows: The purpose of this utility model is to provide a dust suppression device for pneumatic conveying of materials. This dust suppression device is used to "mix and stir" the materials that need to be used with pre-made food, so that the materials sprayed out and used to mix with the pre-made food are in "clumps", thereby preventing them from being suspended in the air for a long time, so that they can quickly fall onto the surface of the pre-made food, ultimately saving processing and mixing time and avoiding waste of materials. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the structure of a dust suppression device for pneumatic material conveying according to the present invention;
[0013] In the diagram, 1-material funnel, 2-falling pipe, 3-unloader, 4-conveying pipe, 5-high-pressure air pump, 6-mixing water pipe, 7-partition cavity. Detailed Implementation
[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0015] Example 1
[0016] like Figure 1 As shown, a dust suppression device for pneumatic conveying of materials is used to "mix and stir" the materials to be used with pre-made food, so that the materials sprayed out and used to mix with the pre-made food are in "clumps", thereby preventing them from being suspended in the air for a long time and avoiding the generation of dust.
[0017] The specific structure of the device includes a material funnel 1, which is used to hold the material to be sprayed and mixed. A control valve is installed at the bottom of the material funnel to control the falling of the material to be sprayed and mixed from the material funnel 1. The bottom of the material funnel 1 is connected to a falling pipe 2 through which the material to be sprayed and mixed passes. A discharge device 3 is installed in the falling pipe 2 to drive the material to be sprayed and mixed through the falling pipe. The end of the falling pipe 2 away from the material funnel 1 is connected to a conveying pipe 4 for conveying the material to be sprayed and mixed. One end of the conveying pipe 4 is used to connect to a high-pressure air pump 5, and the other end of the conveying pipe 4 is used to detachably connect to a high-pressure nozzle structure that sprays the material to be sprayed and mixed.
[0018] In this embodiment, the material to be sprayed and mixed is loaded into the material funnel 1. A control valve is used to control the material's flow rate and speed as it falls from the bottom of the funnel 1 into the drop pipe 2. When the material passes the unloader 3 (an existing device used to assist material passage) in the drop pipe 2, the unloader 3 is controlled to allow the material to fall smoothly from the drop pipe 2 into the conveying pipe 4 connected to it, thus clearing the pipe and preventing blockage. Then, the high-pressure air pump 5 is activated, causing the material in the conveying pipe 4 to be sprayed from a high-pressure nozzle connected to the other end, achieving the purpose of spraying the mixed material over a large area. It should be noted that the materials used in this embodiment include seasonings such as edible salt.
[0019] Example 2
[0020] Based on Example 1, the initial material poured into the material funnel 1 is relatively fine and dry. When it is sprayed out, it will generate dust and be suspended in the air. Therefore, in order to solve this technical problem, a mixing water pipe 6 is connected through the side wall of the falling pipe 2. One end of the mixing water pipe 6 is connected to the water pump through a pipe, and the other end of the mixing water pipe 6 extends into the falling pipe 2 to mix the material that needs to be sprayed and mixed as it passes through the falling pipe.
[0021] In this embodiment, when the material falls from the material funnel 1 into the falling pipe 2, the water pump controls the water to flow from the mixing water pipe 6 into the falling pipe 2 and spray it, so as to "mix" the material in the falling pipe 2 with water, and let the material fall into the conveying pipe 4 in a "clump". At this time, the high-pressure air pump 5 sprays the "clump" material from the high-pressure nozzle structure installed and connected to the other end of the falling pipe 2. When the high-pressure gas introduced by the high-pressure air pump 5 passes through the joint between the falling pipe 2 and the conveying pipe 4, some of the high-pressure gas will enter the falling pipe 2 along with the "rotary starter" of the unloader 3, overflowing from the bottom to the top of the falling pipe 2. This will affect the efficiency of the material falling in the material funnel 1. Therefore, a partition cavity 7 is provided on the outer wall of the material funnel 1. The end of the partition cavity 7 near the falling pipe is connected to the falling pipe 2. Several holes are opened in the partition cavity 7 and the upper part of the material funnel 1. In this way, when the gas passes through the bottom inlet of the material funnel 1, the gas will enter the partition cavity 7 connected to the falling pipe 2, and will bring the material back through the holes back to the material funnel 1, ensuring that the material funnel is not affected by the "backflow". The material back is then circulated back to the material funnel 1 through the partition cavity 7, achieving the purpose of saving materials.
[0022] Example 3
[0023] Furthermore, the high-pressure nozzle structure of this setting includes a high-pressure material nozzle; the end of the high-pressure material nozzle near the conveying pipe is detachably threaded to a connecting telescopic hose, and the end of the connecting telescopic hose away from the high-pressure material nozzle is detachably threaded to the conveying pipe 4.
[0024] In this embodiment, under the action of the high-pressure air pump 5, the material mixed with water and clump together is passed through the connecting telescopic hose connected to the other end of the conveying pipe 4, and then sprayed out through the high-pressure material nozzle. This high-pressure material nozzle enables long-distance spraying, and prevents dust generation during the spraying process. The sprayed clumps of material quickly land on the surface of the pre-made food, reducing their suspension time in the air and saving processing time and raw materials. It should be noted that the connecting telescopic hose used to connect to the end of the conveying pipe 4 can be changed in diameter and the type of high-pressure material nozzle according to the actual material added and the particle size of the clumps, preventing material blockage and compensating for insufficient spraying distance.
