[0050] The utility model provides a dust removal device. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0051] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, and a specific direction structure and operation, and therefore, cannot be understood as a limitation on the present utility model. In addition, "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means more than two.

[0052] See also Figure 1 and Figure 2 The utility model provides a dust removal device, including a first dust extraction pipe 1, a dust removal component 2, a centrifugal fan 3, a discharge pipe 4, a dust collection bag 5 and a magnet 6.

[0053] Wherein, the dust removal component 2 is connected to the first dust extraction pipe 1. The first dust extraction pipe 1 is used to extract the dust generated during the production process so that the dust-containing gas can be pumped into the dust removal component 2 for gas-solid separation treatment. The centrifugal fan 3 is connected to the dust removal component 2, which provides suction force for the dust-containing gas to be pumped into the dust removal component 2. The discharge pipe 4 (the discharge pipe 4 is provided with a discharge valve) is vertically arranged at the discharge port of the dust removal component 2. The dust collecting bag 5 is sleeved on the discharge pipe 4 and is used to collect the dust released from the discharge port of the dust removal component 2. The magnet 6 is magnetically attracted to the discharge pipe 4, and the magnet 6 can more conveniently fix the bag mouth of the dust collection bag 5 on the outer wall of the discharge pipe 4, so that the dust will not fall outside the dust collection bag 5 when it is released from the discharge pipe 4, thereby reducing the pollution of the dust to the workshop environment.

[0054] Since the discharge pipe 4 installed at the discharge port of the dust removal component 2 plays the role of conveying dust and preventing dust from entering the workshop environment, the utility model can eliminate the setting of the dust conveying mechanism, making the collection of dust simpler; and compared with the method of setting a dust storage box, the utility model uses a dust collection bag 5 to collect the dust discharged by the dust removal component 2. After the dust is loaded into the dust collection bag 5, the transportation and subsequent treatment of the dust are more convenient.

[0055] like Figure 1 and Figure 3 As shown, further, the dust removal device further includes a weighing platform 7, a controller and an alarm. The weighing platform 7 is arranged below the discharge pipe 4, the controller is electrically connected to the weighing platform 7, and the alarm is electrically connected to the controller.

[0056] In the present invention, the weighing platform 7 is used to weigh the dust collection bag 5 filled with dust, and the controller can set the weight of dust to be loaded into the dust collection bag 5 (including the weight of the dust collection bag 5 itself). When the weight value of the dust collection bag 5 weighed by the weighing platform 7 is the same as the weight value set by the controller, the controller will control the alarm to sound, thereby reminding the production staff to replace the new dust collection bag 5.

[0057] When the controller controls the alarm to sound, the controller can also simultaneously close the discharge valve on the discharge pipe 4, thereby reducing the amount of dust entering the workshop environment during the process of transferring the dust collection bag 5 filled with dust and replacing the new dust collection bag 5.

[0058] Specifically, the alarm may be an acoustic alarm or an audible and visual alarm.

[0059] Specifically, in order to realize the weighing function of the weighing platform 7, the weighing platform 7 includes a support plate 71 and a weighing sensor 72. The support plate 71 is used to support the dust collection bag 5. The weighing sensor 72 is arranged at the bottom of the support plate 71, and the weighing sensor 72 is electrically connected to the controller.

[0060] like Figure 1 As shown, further, the dust removal assembly 2 includes a cyclone separator 21, a second dust extraction pipe 22 and a bag dust collector 23. The air inlet of the cyclone separator 21 is connected to the first dust extraction pipe 1; the second dust extraction pipe 22 is connected to the air outlet of the cyclone separator 21, and the second dust extraction pipe 22 is connected to the centrifugal fan 3; the air inlet of the bag dust collector 23 is connected to the second dust extraction pipe 22.

[0061] In the present invention, the cyclone separator 21 is used to perform primary treatment on the dusty air in the workshop, so that the dust with a larger specific gravity in the dusty air can be removed by the cyclone separator 21, and finally collected by the dust collection bag 5 located below the discharge pipe 4. The bag dust collector 23 is used to perform secondary treatment on the dusty air, so that the dust with a smaller specific gravity in the dusty air can be removed by the bag dust collector 23, and finally discharged by the discharge pipe 4 connected to the bag dust collector 23 to the dust collection bag 5 for collection.

[0062] The utility model can collect two kinds of dust with different coarseness and fineness ranges by performing secondary dust removal treatment on dust-containing air, thereby facilitating subsequent classification treatment of the dust.

[0063] like Figure 1 As shown, further, the discharge pipe 4 includes a first discharge pipe 41 and a second discharge pipe 42. The first discharge pipe 41 is connected to the discharge port of the cyclone separator 21, and the second discharge pipe 42 is connected to the ash hopper discharge port of the bag dust collector 23. The dust removal component 2 also includes a first vibration motor 25 and a second vibration motor 26. The first vibration motor 25 is arranged on the outer wall of the first discharge pipe 41, and the second vibration motor 26 is arranged on the outer wall of the ash hopper of the bag dust collector 23. The first vibration motor 25 and the second vibration motor 26 can be turned on periodically, wherein the vibration of the first vibration motor 25 can reduce the adsorption of dust on the inner wall of the first discharge pipe 41, and the vibration of the second vibration motor 26 can avoid dust blocking the ash hopper discharge port of the bag dust collector 23, so that the dust collection efficiency obtained by the dust removal component 2 is maintained at a high level.

[0064] like Figure 1 and Figure 4 As shown, further, the dust removal device also includes a supporting platform 8 and an escalator 9.

[0065] The support platform 8 is horizontally arranged beside the bag dust collector 23, and the escalator 9 is vertically arranged on one side of the support platform 8. Production personnel can stand on the support platform 8 with the help of the escalator 9, so as to facilitate the replacement of the bag in the bag dust collector 23.

[0066] like Figure 4 As shown, further, the support platform 8 includes a support frame 81 and a high-strength support net 82 arranged on the support frame 81. Compared with setting up a whole support platform 8 separately, it can save materials and ensure that production personnel can stand stably on the support platform 8 without major safety hazards.

[0067] Furthermore, a reinforcing plate (not shown in the drawings) connected to the outer wall of the bag filter 23 is provided at the bottom of the support frame 81. The provision of the reinforcing plate enables the support frame 81 to be connected to the outer wall of the bag filter 23, thereby improving the connection stability of the support frame 81, and making it safer for production personnel to stand on the support platform 8.

[0068] Furthermore, in order to make it safer for production personnel to stand on the support platform 8, a railing 10 is provided on the support platform 8, and the railing 10 is arranged on the side of the support platform 8 that is not connected to the outer wall of the bag filter 23.

[0069] In summary, the utility model sets a discharge pipe at the discharge port of the dust removal component, and sets a dust collection bag on the discharge pipe, so that the dust discharged by the dust removal component can be transported to the dust collection bag for collection through the discharge pipe. Since the discharge pipe plays the role of transporting dust and preventing dust from entering the workshop environment, the utility model can save the setting of the dust conveying mechanism, making the collection of dust simpler; and compared with the method of setting a dust storage box, the utility model uses a dust collection bag to collect the dust discharged by the dust removal component. When the dust is loaded into the dust collection bag, the transportation and subsequent treatment of the dust are more convenient.

[0070] In addition, the utility model uses a magnet that can be magnetically attracted to the discharge pipe, without the aid of a clamp or a binding rope, so that the bag mouth of the dust collection bag can be fixed on the discharge pipe. When the dust collection bag receives the dust discharged from the discharge pipe, the dust collection bag is in a sealed state, thereby reducing the pollution of dust to the workshop environment.

[0071] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the claims attached to the utility model.
