Description

Dust-free bagging device for filling clinker Technical Field

[0001] This utility model relates to the technical field of powder filling equipment, and in particular to a dust-free bag filling device for filling clinker. Background Technology

[0002] Filler clinker is a substance used in building materials, typically to improve the performance of concrete materials, such as increasing strength, improving durability, or reducing costs. Since filler clinker is usually made primarily of limestone, clay, and iron-based raw materials, powder filling equipment is required during the filler clinker packaging stage.

[0003] In the existing technology, some powder filling machines on the market are not equipped with dustproof structures, or the dustproof structures of powder filling machines are relatively simple, which causes a large amount of dust to be generated during the bagging stage of the filler clinker, which not only pollutes the environment, but also increases the waste of filler clinker.

[0004] To address this issue, a dust-free bagging device for filling clinker is proposed, which has the advantages of dust-free filling and powder recovery, thereby solving the problems mentioned in the background technology. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dust-free bagging device for filling clinker.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dust-free bagging device for filling clinker, comprising a filling shell and a powder filling head mounted on its top surface, a recycling box welded to the back of the filling shell, and a dust extraction fan fixed to the top of the recycling box, a filter cover connected to the recycling box being provided at the air intake of the dust extraction fan, and an absorption pipe connected to the left and right sides of the top surface of the recycling box, and the two absorption pipes respectively penetrating the filling shell and connecting to a first absorption cover and a second absorption cover, a powder filling head mounted on the top of the filling shell, the bottom of the powder filling head extending to the inside of the filling shell, and the top of the powder filling head connected to an external powder filling machine, a door-shaped baffle welded to the opening of the front surface of the filling shell, and a water tank welded to the lower part of the front surface of the filling shell.

[0007] As a further description of the above technical solution: the top surface of the water tank is connected to a water pipe, and the water pipe is in an inverted L-shaped structure. Several water outlets are arranged side by side at the upper end of the water pipe. The top surface of the water tank is provided with a return water port corresponding to the several water outlets. The bottom end of the water pipe is connected to a filter head, and the filter head is filled with activated carbon. A water pump is installed on the surface of the water pipe.

[0008] As a further description of the above technical solution: the water pipe is provided with multiple connecting posts facing the gate-shaped baffle, and all the multiple connecting posts are fixedly connected to the gate-shaped baffle.

[0009] As a further description of the above technical solution: there are two of each of the first and second absorption covers, with the two first absorption covers distributed at the upper end of the filling shell and the two second absorption covers distributed at the lower end of the filling shell.

[0010] As a further description of the above technical solution: a mechanical clamping arm is welded to both the left and right sides inside the filling shell, and each mechanical clamping arm has a Y-shaped structure, and a suction cup is installed on both inner sides of each mechanical clamping arm.

[0011] As a further description of the above technical solution: a filter screen is installed at the connection between the filter cover and the recycling bin; two baffles are symmetrically welded to the top inner side of the recycling bin corresponding to the filter screen; and a cleaning panel is installed at the pre-reserved opening on the surface of the recycling bin by screws.

[0012] This utility model has the following beneficial effects:

[0013] In this invention, a filling shell, a recycling bin, a gate-shaped baffle, an absorption pipe, a first absorption hood, and a second absorption hood are used to construct a bagging device for filling clinker. By starting the dust extraction fan, the fan draws air from inside the recycling bin through the filter hood at the air intake. This creates a negative pressure environment inside the recycling bin, which then forms a dust absorption path through the absorption pipe, the first absorption hood, and the second absorption hood. The first and second absorption hoods, located at the upper and lower ends inside the filling shell, continuously absorb the powder that flies out during the filling process and collect it in the recycling bin. At this time, the gate-shaped baffle reduces the size of the opening on the front surface of the filling shell, reducing the diffusion of flying powder to the outside. Combined with the shielding effect of the filling shell, a dust-free bagging effect is achieved.

[0014] In this invention, a water tank is installed at the lower part of the front surface of the filling shell, and a gate-shaped baffle is welded at the opening of the front surface of the filling shell. By starting the water pump on the surface of the water pipe, the filter cover at the bottom of the water pipe filters and draws water from the water tank. The water then flows out from several water outlets arranged side by side at the top of the water pipe, forming a water curtain at the opening of the gate-shaped baffle. This absorbs the dust that is about to leave the filling shell, thereby preventing dust from spreading outward during the filling stage of clinker bagging and further improving the dust removal effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] According to an embodiment of the present invention, a dust-free bag filling device for filling clinker is provided.

[0023] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. As shown in Figures 1-4, the dust-free bagging device for filling clinker according to an embodiment of the present invention includes a filling shell 1 and a powder filling head 2 mounted on its top surface. A recycling box 3 is welded to the back of the filling shell 1, and a dust extraction fan 12 is fixed to the top of the recycling box 3. A filter cover 13 connected to the recycling box 3 is provided at the air intake of the dust extraction fan 12. An absorption pipe 7 is connected to the left and right sides of the top surface of the recycling box 3, and the two absorption pipes 7 respectively penetrate the filling shell 1 and are connected to a first absorption cover 10 and a second absorption cover 11. The powder filling head 2 is mounted on the top of the filling shell 1, and the bottom of the powder filling head 2 extends to the inside of the filling shell 1. The top of head 2 is connected to an external powder filling machine. A door-shaped baffle 5 is welded to the open end of the front surface of filling shell 1, and a water tank 4 is welded to the lower part of the front surface of filling shell 1. The principle of powder filling machine head 2 is existing known technology and there are mature products. Therefore, its principle will not be further explained. The contents not described in detail in this specification are existing technologies known to those skilled in the art. The water pump 8 and dust extraction fan 12 of this device are controlled by manual start and stop switches. The wiring diagram of the power components and the power supply are common knowledge in the art. Since this utility model is mainly used to protect mechanical devices, the control method and wiring arrangement will not be explained in detail in this utility model.

[0024] In one embodiment, the top surface of the water tank 4 is connected to a water pipe 6, and the water pipe 6 has an inverted L-shaped structure. Several water outlets 15 are arranged side by side at the upper end of the water pipe 6. A return water port 16 is opened on the top surface of the water tank 4 corresponding to the several water outlets 15. The bottom end of the water pipe 6 is connected to a filter head 17, and the filter head 17 is filled with activated carbon. A water pump 8 is installed on the surface of the water pipe 6. With this structure, by starting the water pump 8 on the surface of the water pipe 6, the filter cover 13 at the bottom of the water pipe 6 is activated to filter and draw water from the water tank 4. The water then flows out from the several water outlets 15 arranged side by side at the upper end of the water pipe 6, forming a water curtain at the opening of the gate-shaped baffle 5. This absorbs the dust that is about to leave the filling shell 1, further preventing dust leakage. The return water port 16 is used to recover the falling water, achieving the effect of water recycling.

[0025] In one embodiment, the water pipe 6 is provided with multiple connecting posts facing the gate-shaped baffle 5, and all the connecting posts are fixedly connected to the gate-shaped baffle 5. This structure increases the reliability of the connection between the water pipe 6 and the gate-shaped baffle 5 and enhances the dust-blocking effect of the water curtain.

[0026] In one embodiment, two first absorption hoods 10 and two second absorption hoods 11 are provided. The two first absorption hoods 10 are distributed at the upper end of the inside of the filling shell 1, and the two second absorption hoods 11 are distributed at the lower end of the inside of the filling shell 1. This structure is beneficial for fully absorbing the "dust" flying inside the filling shell 1.

[0027] In one embodiment, a mechanical clamping arm 9 is welded to both the left and right sides inside the filling shell 1, and each mechanical clamping arm 9 has a Y-shaped structure. A suction cup is installed on both sides of the inner side of each mechanical clamping arm 9. With this structure, it is easy to adsorb the opening of the packaging bag by the action of the suction cup. Combined with conventional blowing equipment, it is easy to open the packaging bag.

[0028] In one embodiment, a filter screen is installed at the connection between the filter cover 13 and the recycling bin 3. Two baffles are symmetrically welded to the top inner side of the recycling bin 3 corresponding to the filter screen. A cleaning panel 14 is installed at the opening reserved on the surface of the recycling bin 3 by screws. With this structure, the baffles can block the powder recovered in the recycling bin 3 to a certain extent, preventing the filter screen from clogging. By disassembling the cleaning panel 14, it is easy to clean the recovered powder in the recycling bin 3.

[0029] Working principle:

[0030] In operation, the six-axis robot first uses its suction cups to pick up the packaging bag and insert it into the filling shell 1. Then, the mechanical grippers 9, symmetrically installed inside the filling shell 1, and the corresponding blowing equipment open the packaging bag, allowing the filling material to be introduced into the packaging bag through the powder filling head 2. When dust is collected, the dust extraction fan 12 is activated, causing it to draw air from the inside of the collection box 3 through the filter cover 13 at the air intake. This creates a negative pressure inside the collection box 3, which forms a dust absorption path through the absorption pipe 7, the first absorption cover 10, and the second absorption cover 11. This allows the first and second absorption covers 10 and 11, located at the upper and lower ends inside the filling shell 1, to absorb the dust. The system continuously absorbs the powder that flies out during the filling stage of the clinker and collects it in the recycling box 3. At this time, the gate-shaped baffle 5 can reduce the size of the opening on the front surface of the filling shell 1, reducing the diffusion of flying powder to the outside. At the same time, by starting the water pump 8 on the surface of the water pipe 6, the filter cover 13 at the bottom of the water pipe 6 filters and draws water from the water tank 4, and then flows out from several water outlets 15 arranged side by side at the top of the water pipe 6, forming a water curtain at the opening of the gate-shaped baffle 5, absorbing the dust that is about to leave the filling shell 1, further preventing dust leakage, until the power of the water pump 8 is cut off when the bagged clinker is discharged from the filling shell 1, so as to facilitate the discharge of the clinker after bagging.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
