Description

Technical Field

[0001] The utility model relates to the technical field of particle recovery, in particular to a particle leakage recovery device for preparing composite filter materials. Background Art

[0002] Patent publication number CN118001840A discloses an air purification material and its preparation method and application; the multifunctional composite filter material is also called high-efficiency HEPA potassium permanganate composite filter material, and its preparation method includes the following steps: (1) spraying the binder on the support layer, and then evenly sprinkling the air purification material on the support layer; (2) spraying the binder on the filter layer, and then bonding it with the support layer with the binder and air purification material obtained in step (1) to form a multifunctional composite filter material with a sandwich structure. Among them, the air purification material is granular, including a porous carrier and an oxidant and an activator loaded on the porous carrier, the oxidant is potassium permanganate or sodium permanganate; the activator is one or more of trifluoromethanesulfonate and nitrate; the porous carrier is activated alumina. The air purification material is used for air purification, sterilization, etc.

[0003] The above-mentioned granular air purification material needs to be evenly sprinkled on the supporting layer. The patent with patent publication number CN212441899U discloses a particle blanking mechanism and a substrate multi-layer structure composite machine. By setting a blanking roller and a brush roller that cooperate with each other, the granular material can be evenly coated on the substrate; by setting a leaked material recovery groove, when cleaning and repairing the particle blanking mechanism, the excess leaked material can be more conveniently and easily recovered and reused.

[0004] However, the particulate material collected in the leakage recovery trough cannot be fully guided to the guide pipe by the guide slope only by gravity, and some particulate material will still adhere to the guide slope. In addition, when the particle dropping mechanism transports the particulate material to the supporting layer cloth, the leakage recovery trough mainly collects the particulate material leaked from both sides of the supporting layer cloth in the width direction, and the above-mentioned leakage recovery trough is only provided with one guide pipe. Therefore, the position of the guide slope away from one side of the guide pipe, that is, the upper part of the guide slope will continue to receive about half of the particulate material. This part of the particulate material must pass through almost the entire length of the guide slope to reach the guide pipe, which results in particulate material passing through and adhering to most of the area of ​​the guide slope, resulting in poor particulate material collection effect and frequent manual cleaning. Utility Model Content

[0005] Based on this, it is necessary to provide a particle leakage recovery device for preparing composite filter materials in order to solve the above technical problems.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a particle leakage recovery device for preparing a composite filter material, comprising a recovery hopper, wherein two symmetrically distributed material troughs are arranged in the recovery hopper, the tops of the two material troughs are connected, and discharge ports are arranged at the bottoms of the two opposite sides of the two material troughs; an air jet is rotatably installed on the recovery hopper and located at the junction of the tops of the two material troughs, one end of the air jet is connected to a high-pressure gas source, and a plurality of air jets are arranged on the air jet along its axial direction; a driving mechanism is installed on the recovery hopper, and the driving mechanism is used to drive the air jet to rotate so as to adjust the air jet angle of the air jet.

[0007] Preferably, the driving mechanism includes a mounting frame, a cylinder, and a connecting piece. The mounting frame is fixedly connected to the recovery hopper, the cylinder is hingedly mounted on the mounting frame, the cylinder output end is hinged to the connecting piece, and the end of the connecting piece away from the cylinder is fixedly connected to the injection pipe.

[0008] Preferably, one end of the air jet pipe is closed, and the other end is connected to the high-pressure air source through a hose.

[0010] Preferably, the center of the bottom of the two opposite sides of the troughs is the lowest point of the trough, and the discharge port is located at the lowest point of the trough.

[0011] Preferably, a feeding pipe is installed at the discharge port.

[0012] Preferably, the discharge port is a rectangular port, and the rectangular discharge pipe is a square pipe adapted to the discharge port.

[0013] The beneficial effects of this technical solution are as follows: by setting up two troughs, the leaked granular materials can move to the discharge port in a shorter path, reducing the total contact area between the granular materials and the hopper, thereby reducing the probability of granular materials adhering to the inner wall of the hopper and reducing the cleaning cycle;

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] See also Figures 1 to 4 The embodiment of the present application provides a particle leakage recovery device for preparing a composite filter material, including a recovery hopper 1, wherein two symmetrically distributed material troughs 2 are arranged in the recovery hopper 1, the tops of the two material troughs 2 are connected, and discharge ports 3 are arranged at the bottoms of the opposite sides of the two material troughs 2, and the center of the bottoms of the opposite sides of the two material troughs 2 is the lowest point of the material troughs 2, and the discharge port 3 is located at the lowest point of the material troughs 2, so that most of the particulate materials can move to the discharge port 3 with the shortest moving route; an injection pipe 4 is rotatably installed on the recovery hopper 1 and located at the junction of the tops of the two material troughs 2, one end of the injection pipe 4 is connected to a high-pressure air source, and the high-pressure air source can be an air pump or a fan, which is not shown in the drawings, and a plurality of injection ports 5 are arranged on the injection pipe 4 along its axial direction; a driving mechanism is installed on the recovery hopper 1, and the driving mechanism is used to drive the injection pipe 4 to rotate to adjust the injection angle of the injection port 5 so that the injection port 5 can spray to any material trough 2.

[0022] The driving mechanism includes a mounting frame 6, a cylinder 7, and a connecting piece 8. The mounting frame 6 is fixedly connected to the recovery hopper 1, the cylinder 7 is hingedly mounted on the mounting frame 6, the output end of the cylinder 7 is hingedly connected to the connecting piece 8, and the end of the connecting piece 8 away from the cylinder 7 is fixedly connected to the jet pipe 4. The connecting piece 8 is driven by the cylinder 7 to move, and the connecting piece 8 drives the jet pipe 4 to rotate. The rotation angle of the jet pipe 4 ranges from 0 to 150 degrees, so that the jet pipe 4 can spray to the two troughs 2 respectively.

[0023] In order to facilitate the high-pressure gas introduced into the jet pipe 4 to be ejected from the jet port 5, one end of the jet pipe 4 is closed; since the jet pipe 4 needs to be rotated to change the injection angle of the jet port 5, in order to facilitate the jet pipe 4 to maintain communication with the high-pressure gas source when rotating, the other end of the jet pipe 4 is connected to the high-pressure gas source through a hose 9.

[0024] In order to facilitate the control of the air intake of the jet pipe 4, a valve 10 is installed on the hose 9. The valve 10 is a solenoid valve or a manual valve. In other embodiments, the valve 10 can also be installed on the jet pipe 4.

[0025] In order to make the granular material discharged from the discharge port 3 fall stably to the collection container below, a discharge pipe 11 is installed at the discharge port 3. By placing the collection container below the discharge pipe 11, the granular material discharged from the discharge port 3 is guided by the extended discharge pipe 11 and stably enters the collection container.

[0026] In order to fully discharge the granular material in the trough 2, the discharge port 3 is set to be a rectangular port, and the rectangular discharge pipe 11 is a square pipe adapted to the discharge port 3. The discharge port 3 is adapted to the size and shape of the bottom of the trough 2, and the material in the trough 2 can basically enter the discharge port 3, thereby improving the discharge effect.

[0027] During operation, the support layer fabric of the high-efficiency HEPA potassium permanganate composite filter material passes over the hopper, and the granular material is spread on the support layer fabric. The hopper width is greater than the width of the support layer fabric, and a small amount of granular material will leak out from both sides of the support layer fabric in the width direction, fall into both sides of the hopper, and enter two troughs 2 respectively; the granular material leaking out from both sides of the support layer fabric in the width direction can fall into the discharge port 3 in a shorter path, and be discharged from the discharge port 3 and the discharge pipe, thereby reducing the total contact area between the granular material and the hopper, reducing the probability of the granular material adhering to the inner wall of the hopper, and reducing the cleaning cycle;

[0028] Moreover, after working for a period of time, by opening the valve 10, the high-pressure gas source is controlled to pass high-pressure gas into the hose 9 and the jet pipe 4, so that the jet port 5 sprays high-pressure gas into the material trough 2 to clean the particulate materials attached to the inner wall of the material trough 2, without the need for manual cleaning, thereby reducing the labor intensity and improving the cleaning efficiency; by controlling the cylinder 7 to work, the cylinder 7 drives the connecting piece 8 and the jet pipe 4 to rotate, and the angles of the jet pipe 4 and the jet port 5 are adjusted, so that the jet pipe 4 sprays toward another material trough 2.
