Description

Technical Field

[0001] The utility model relates to the technical field of surfactant production, in particular to an intelligent feeding device for toxic powder. Background Art

[0002] Surfactants are a class of chemicals widely used in various applications. They play a role in reducing the surface tension between water and oil, allowing them to mix and disperse. The production of surfactants usually requires some basic raw materials, such as petrochemical products, natural oils and fats, alkaline substances, etc. These raw materials need to be strictly selected and prepared to ensure the stability of the production process and the quality of the product. The raw materials undergo a series of chemical reactions to form the desired surfactant molecular structure;

[0003] The raw materials added in the production process of surfactants involve some special chemical raw materials, some of which may be toxic or dangerous. In the process of adding such powders, the safety operating procedures must be strictly followed, and appropriate protective measures must be taken to ensure the safety of the staff and the environment. In order to improve the safety of the staff, a special feeding device must be used to feed the powder when adding such powders. The feeding device and the reactor are kept sealed to avoid powder leakage. The existing feeding device has the following problems in the feeding process:

[0004] 1. Most powders are shipped in sealed bags. When the staff conducts the initial feeding, they must manually open the packaging table and pour the powder into the feeding equipment. During the process of punching the packaging bag, some powder will float in the air and it is difficult to dissipate, which is not safe enough.

[0005] 2. The particles of powder are relatively fine, and a lot of powder is adsorbed inside the packaging bag. If you shake the packaging bag vigorously, more powder will float in the air. If you don’t shake it vigorously, a lot of raw materials will remain inside the packaging bag. These residual raw materials are generally thrown away with the packaging bag, resulting in a waste of resources. Utility Model Content

[0006] The purpose of the utility model is to provide an intelligent feeding device for toxic powders, so as to solve the problem that in the process of adding powders, there will be powders floating in the air, which poses a potential risk, and the powders in the packaging bag cannot be completely poured out, resulting in waste. To achieve the above purpose, the utility model provides the following technical solutions: an intelligent feeding device for toxic powders, including a silo, wherein a bag breaking component and a recovery component are provided inside the silo, and a discharge pipe and a vibration component are provided at the bottom of the silo.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: an intelligent feeding device for toxic powder, comprising a silo 1, a bag breaking component 2 and a recovery component 3 are arranged inside the silo 1, and a discharge pipe 4 and a vibration component 5 are arranged at the bottom of the silo 1.

[0024] The bag breaking assembly 2 includes a rotating frame 201, a blade 202 is welded on the surface of the rotating frame 201, a driving wheel 203 is installed at one end of the rotating frame 201, a belt 204 is connected to the surface of the driving wheel 203, and the other end of the belt 204 is connected to the driven wheel 205, and a first motor 206 is installed on one side of the driving wheel 203.

[0025] The recovery component 3 includes a recovery bin 301, the top of the inner wall of the recovery bin 301 is rotatably connected to a screw rod 302, the surface of the screw rod 302 is threadedly connected to a slider 303, a cylinder 304 is installed at the bottom of the slider 303, a vacuum clamp 305 is installed at one end of the cylinder 304, and a second motor 306 is installed at one end of the screw rod 302.

[0026] In this embodiment, Figure 1 As shown, the vibration component 5 includes a vibration plate 501, a vibration motor 502 and a spring 503 are installed at the bottom of the vibration plate 501, a bottom plate 504 is welded to the other end of the spring 503, and a bracket 505 is welded to the bottom of the bottom plate 504; it should be noted that the vibration component 5 drives the entire device to vibrate. As the silo 1 vibrates, once the packaging bag of the powder is broken by the blade 202, the powder inside will leak downward and fall directly into the discharge pipe 4.

[0027] In this embodiment, Figure 3 and Figure 4 As shown, there are four rotating frames 201 in total, and the rotating frames 201 are rotated by the first motor 206; it should be noted that when the rotating frame 201 is driven by the first motor 206 to rotate clockwise, the powder bag is automatically conveyed to the side of the recovery component 3, and as the rotating frame 201 rotates, the blade 202 on its surface will continuously scratch the packaging bag of the powder bag, tearing the packaging bag of the powder bag, thereby realizing feeding while conveying.

[0028] In this embodiment, Figure 2 and Figure 4 As shown, the driving wheel 203, the belt 204 and the driven wheel 205 are set as a group, and there are three groups in total; it should be noted that the four rotating frames 201 are connected together through the three groups of components, so that the rotation direction and rotation rhythm of each rotating frame 201 are consistent, and the transmission process is relatively stable, and the powder bag can be stably transmitted.

[0029] In this embodiment, Figure 2 and Figure 3 As shown, the second motor 306 adopts a servo motor, and the slider 303 performs linear reciprocating motion through the second motor 306; it should be noted that the second motor 306 can rotate forward and reverse. When the second motor 306 rotates forward, it drives the slider 303 and the vacuum clamp 305 at the bottom to slide from left to right. When the second motor 306 reverses, it drives the slider 303 and the vacuum clamp 305 at the bottom to move from right to left. In conjunction with the lifting and lowering of the cylinder 304, the powder bag after unloading is automatically transported to the recovery bin 301. During the feeding and recovery process, the staff will not contact the powder, and the recovery process is more intelligent and safer.

[0030] In this embodiment, Figure 1As shown, a material guide plate 101 is installed at one end of the silo 1, an air hole 102 is provided on the top of the silo 1, and a storage rack 103 is welded on the inner wall of the silo 1; it should be noted that the storage rack 103 is used to shield the powder bag to prevent the powder bag from falling to the pipe mouth of the discharge pipe 4 at the bottom, and the air hole 102 on the top of the silo 1 is convenient for the air pipe of the vacuum clamp 305 below to pass through. The top of the vacuum clamp 305 is inserted into the air pipe and connected to the vacuum generator, so that the powder bag can be picked up by the vacuum clamp 305.

[0031] The use method and advantages of the utility model: The intelligent feeding device for toxic powder materials, when in use, works as follows:

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, the sealed powder bag is directly put into the silo 1 from the guide plate 101, and the first motor 206 is started. The first motor 206 drives the driving wheel 203 to rotate clockwise, and the transmission is carried out through the belt 204. The four rotating frames 201 start to rotate clockwise synchronously. The first motor 206 adopts a reduction motor. When the rotating frame 201 rotates, the powder bag is slowly and evenly transmitted. During the transmission process, the blade 202 will continuously scrape against the powder bag to cut the powder bag, and cooperate with the vibration motor 502 and the spring 503 at the bottom to drive the vibration plate 501 and the silo 1 to vibrate at a high frequency, which further drives the internal powder bag to vibrate, and vibrates the internal powder to the discharge. The discharge pipe 4 is in the reactor, and the material can be smoothly fed by aligning the discharge pipe 4 with the reactor. When the powder bag passes the last rotating frame 201, it will fall onto the storage rack 103. At this time, the piston rod of the cylinder 304 moves downward, driving the vacuum clamp 305 to move downward. The vacuum clamp 305 adopts the model ZDBLSO. The air pipe on the top of the vacuum clamp 305 is connected to the vacuum generator. The powder bag can be automatically picked up by the vacuum clamp 305. The second motor 306 drives the slider 303, the vacuum clamp 305 and the empty powder bag at the bottom to transfer to the recovery bin 301. During the transfer process, the vibration component 5 vibrates continuously to fully shake the powder in the powder bag and shake out the remaining material in the packaging bag.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
