Abstract
Description
Technical Field
[0001] This utility model relates to the field of production equipment for grinding media of ceramic materials. More specifically, this utility model relates to a stirring device with a dust removal system. Background Technology
[0002] In the production process of ceramic grinding media (such as alumina, zirconium oxide, silicon carbide, silicon nitride, etc. ceramic grinding beads), water and powder need to be added to a mixing tank to achieve uniform mixing of the slurry. When powder is added to the mixing tank through the feed port, or when additional powder needs to be added through the feed port during the mixing process, the dust raised will overflow from the feed port with the airflow. The large amount of dust overflow will affect the environment of the work area and the health of the operators.
[0003] In existing technologies, a dust collection device is typically installed above the mixing tank to absorb overflowing dust. However, such dust collection devices are relatively complex in structure, and during the feeding process, large material bags (also known as ton bags) need to be moved above the feeding port of the mixing tank. Therefore, the space for the dust collection device above the mixing tank (especially the height space) is limited, and its position from the feeding port is also relatively far, resulting in poor dust collection efficiency and making it difficult to ensure that the dust concentration is controlled within the ideal range. Utility Model Content
[0004] The purpose of this invention is to provide a mixing device with a dust removal system to overcome at least one of the defects in the prior art. More specifically, the dust removal system of the mixing device according to this invention can efficiently collect dust during the feeding process into the mixing tank, which is not only beneficial to the environment of the working area and the health of the operators, but also facilitates the recycling of powder.
[0005] To this end, the present invention provides a mixing device, comprising: a mixing tank and a stirrer, the mixing tank including a shell defining an internal space suitable for containing materials and having an inlet suitable for adding materials into the internal space, the stirrer being at least partially positioned in the internal space to stir materials; and a main dust removal system including a first pipe, a first gas driving mechanism and a first dust collection unit, a first end of the first pipe passing through the shell and communicating with the internal space, a second end of the first pipe communicating with the first dust collection unit, and the first gas driving mechanism being disposed on the first pipe to be adapted to draw material dust from the internal space through the first pipe and into the first dust collection unit when the first gas driving mechanism is in operation.
[0006] Based on the above technical concept, the present invention may further include any one or more of the following optional forms.
[0007] In some alternative forms, the mixing device further includes an auxiliary dust removal system, which includes a second pipe, a second gas drive mechanism, and a second dust collection unit. A first end of the second pipe is adjacent to the feed inlet and located outside the housing. A second end of the second pipe is connected to the second dust collection unit. The second gas drive mechanism is disposed on the second pipe to be adapted to draw material dust overflowing from the feed inlet into the second dust collection unit when the second gas drive mechanism is in operation.
[0008] In some alternative configurations, the first dust collection unit and / or the second dust collection unit are flexible filter bags with pore sizes between 2 μm and 3 μm.
[0009] In some alternative configurations, the first gas drive mechanism is disposed at the second end of the first pipe, and / or the second gas drive mechanism is disposed at the second end of the second pipe.
[0010] In some alternative forms, the first end of the first pipe passes through the top of the housing and communicates with the interior space.
[0011] In some alternative configurations, the main dust removal system further includes an air distribution component disposed on the first duct to regulate the airflow through the first duct.
[0012] In some alternative configurations, the air distribution component is located at the first end of the first duct.
[0013] In some alternative configurations, the mixing device further includes a control module electrically connected to the agitator and the main dust removal system.
[0014] In some alternative forms, the mixing device includes a plurality of agitators, the plurality of agitators including at least one first agitator adapted to operate when material is added to the internal space and at least one second agitator operating at a lower speed than the first agitator, the control module being configured to operate the main dust removal system only when the at least one first agitator is running.
[0015] In some alternative forms, the mixing device further includes a deodorization system that is in communication with the internal space and electrically connected to the control module, the control module being configured to operate the deodorization system only when the mixer is running.
[0016] Compared to existing technologies, the mixing equipment according to this utility model has several beneficial technical effects, especially: the mixing tank has been improved by connecting the dust collection system to the mixing tank through a dust suction pipe. This allows a negative pressure to be created inside the mixing tank during the operation of the gas-driven mechanism, causing large powder particles to settle to the bottom of the mixing tank under gravity. Simultaneously, finer dust particles are drawn in through the dust suction pipe and collected in the dust collection unit. Therefore, it effectively prevents large amounts of dust from overflowing from the mixing tank's feed port, thus reducing the dust concentration in the working environment from, for example, 0.2 mg / m³. 2 Reduced to 0.15 mg / m³ 2 This system not only benefits the health of operators but also makes it easier to recycle the powder collected in the dust collection unit. In addition, the dust removal system is low in cost, has high dust collection efficiency, is easy to operate, and occupies a small area. It can be easily installed near the dust generation point to avoid production line damage. Therefore, it can be widely used in various types of mixing equipment. Attached Figure Description

It should be understood that these drawings are not only for explaining and illustrating the present invention, but also, where necessary, for defining the present invention. Detailed Implementation
[0022] The implementation and use of specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of particular ways of implementing and using this utility model, and are not intended to limit the scope of this utility model.
[0023] In this manual, the descriptions of the structural positions of various components, such as "up," "down," "top," "bottom," "horizontal," and "vertical," are not absolute but relative. These directional descriptions are appropriate when the components are in their normal operating positions as shown in the figure; however, these directional descriptions should be changed accordingly when the positions of the components change.
[0024] In this specification, unless otherwise expressly specified and limited, terms such as "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this specification according to the specific circumstances.
[0025] The preferred embodiments of this utility model will now be described with reference to the accompanying drawings.
[0026] Figure 1 This is a schematic diagram of the first embodiment of the mixing device according to the present invention. Figure 1 As shown, the mixing device according to this first embodiment mainly includes a mixing tank 100, a stirrer 200, a main dust removal system 300, and a control module. The control module is electrically connected to the stirrer 200 and the main dust removal system 300 to control the operation of the stirrer 200 and the main dust removal system 300, and can be used to realize the linkage control between the stirrer 200 and the main dust removal system 300. The control module can be implemented by a control circuit, or by other methods known in the art.
[0027] The mixing tank 100 includes a generally cylindrical shell 110 defining an internal space 120 for containing materials, and a feed inlet for adding materials into the internal space 120 is provided on the top wall 111 of the shell 110. It will be understood that the feed inlet is located on the top wall 111 of the shell 110 and... Figure 1 The material bag 500 is shown in the vertically aligned position. The top wall 111 can be the upper wall of the integral housing 110, or it can be a separate top cover that is detachable from the side wall 112 of the housing 110. When it is necessary to add powder to the internal space 120, for example, the material bag 500 containing powder can be hung by the movable hook device 600, and the material bag 500 can be moved above the feed inlet of the top wall 111 of the housing 110, and then the feed inlet can be opened to add the powder.
[0028] The number of agitators 200 is typically multiple, including, for example, at least one first agitator 210 and at least one second agitator 220. The figure only schematically shows one second agitator 220 located at the center of the mixing tank 100 and two first agitators 210 located on either side of the second agitator 220. Each agitator 200 is at least partially positioned within the internal space 120 for agitating materials. It is understood that the agitation device may also include other agitators not shown. In fact, the number of first agitators 210 and second agitators 220 is not limiting and can be determined according to actual needs. In this embodiment, the first agitator 210 is a high-speed agitator, typically activated when material is added to the internal space 120 of the mixing tank 100, ensuring that the powder added to the internal space 120 remains as uniform as possible within the internal space 120, preventing material agglomeration. The second agitator 220 is a slow agitator with a significantly lower operating speed than the first agitator 210, also known as a conventional agitator. This slow / conventional agitator is used to maintain operation after material addition to achieve uniform agitation of the slurry. For example, the control module can be configured to operate the first agitator 210 only when material is being added to the internal space 120. Specifically, the first agitator 210 will automatically start when the feed port is detected to be open or powder is being added to the internal space 120, and automatically stop when the feed port is detected to be closed or feeding has stopped. Alternatively, the first agitator 210 can be manually started before powder is added to the internal space 120 and manually stopped after feeding is completed or under other circumstances.
[0029] The main dust removal system 300 includes a first pipe 310, a first gas drive mechanism 320, and a first dust collection unit 330, and is connected to the mixing tank 100 through the first pipe 310. The first end 311 of the first pipe 310 extends into the internal space 120 through the top wall 111 of the housing 110 at the top of the mixing tank 100 (or it can be designed to extend through the top or slightly above the side wall 112 of the housing 110) and is in fluid communication with the internal space 120. The second end 312 of the first pipe 310, opposite to its first end 311, is in fluid communication with the first dust collection unit 330. The first gas drive mechanism 320 is disposed on the first pipe 310, preferably disposed at the second end 312 of the first pipe 310 as shown in the figure, so that the main dust removal system 300 can draw material dust from the internal space 120 and flow through the first pipe 310 when the first gas drive mechanism 320 is running, until it is drawn in and collected in the first dust collection unit 330.
[0030] More specifically, the first gas drive mechanism 320 can be, for example, a suitable model of low-power, low-noise fan, or other suction devices such as an air pump. When the first gas drive mechanism 320 is started, it can create a negative pressure in the internal space 120 of the mixing tank 100. This helps large powder particles settle to the bottom of the mixing tank 100 under gravity, while finer dust particles are drawn into the first pipe 310 through the first end 311. When the dust-laden air enters the housing of the first gas drive mechanism 320, for example from the second end 312 of the first pipe 310, the sudden expansion of the airflow causes a decrease in velocity, and the dust can be retained in the first dust collection unit 330. The purified air can then be discharged through the opening of the first dust collection unit 330. The first pipe 310 is made of polymer materials such as PVC (polyvinyl chloride). The first dust collection unit 330 can be, for example, a flexible filter bag with a pore size between 2μm and 3μm, or any other type of flexible or rigid dust collection container. It is understood that the first dust collection unit 330 with a suitable pore size can be selected according to the size of the powder particles to ensure effective dust collection while preventing dust leakage from the first dust collection unit 330. When the dust accumulates to approximately 5%-10% of the volume of the first dust collection unit 330, the first dust collection unit 330 can be removed, the dust emptied, and the first dust collection unit 330 can be reused or replaced. The first dust collection unit 330 can be fixed, for example, with a stainless steel hose clamp for easy disassembly. Therefore, this invention overcomes the shortcomings of traditional dust collection devices, such as high power consumption, high energy consumption, and difficulty in replacing filter bags. Testing has shown that by using this main dust collection system 300, the dust concentration in the dusty area of the working environment can be reduced, for example, from 0.2 mg / m³. 2 Reduced to 0.15 mg / m³ 2 This not only benefits the health of operators, but also makes it easier for the powder collected in the first dust collection unit 330 to be recovered and recycled.
[0031] Preferably, the main dust removal system 300 can be controlled by the control module to operate only when at least one first agitator 210 is running. That is, the first gas drive mechanism 320 of the main dust removal system 300 is automatically started when at least one first agitator 210 is running, so as to absorb dust, for example, during material feeding, and the first gas drive mechanism 320 of the main dust removal system 300 is automatically stopped when any one of the first agitators 210 is stopped. Of course, the main dust removal system 300 can also be manually turned on or off at any time as needed.
[0032] Preferably, the main dust removal system 300 may further include an air distribution component 340 (or "air outlet"), which is disposed on the first duct 310 for regulating the airflow through the first duct 310. Figure 2 This is a schematic diagram of one embodiment of the air distribution component 340 of the mixing equipment. For example... Figure 2 As shown, the air distribution component 340 is disposed, for example, at the first end 311 of the first duct 310, i.e., at the air inlet end of the first duct 310, and can adjust the airflow through the first duct 310 by changing the cross-sectional area of the first duct 310. For example, according to a non-limiting embodiment, the air distribution component 340 may include two air distribution plates 341 stacked on top of each other and having air inlets. These two air distribution plates 341 can be rotated relative to each other to change the size of the air inlets, thereby adjusting the airflow. Therefore, for example, when the properties of the powder change, the air distribution can be adjusted by the air distribution component 340 to change the dust collection capacity. In addition, the advantage of disposing of the air distribution component 340 at the first end 311 of the first duct 310 is that after feeding, the slurry in the mixing tank 100 may be splashed up and block the air inlet end of the first duct 310 under long-term stirring and rotation. Therefore, the air inlet end of the first duct 310 can be cleaned at the location of the air distribution component 340, for example, by removing the air distribution component 340.
[0033] In addition, the mixing equipment may include one or more other systems independent of the main dust removal system 300, such as a deodorization system (not shown), which is connected to the internal space 120 of the mixing tank 100 via piping and can be electrically connected to the control module. Preferably, the deodorization system can be controlled by the control module to operate only when one or more agitators 200 are running, so as to achieve deodorization during slurry mixing. The specific structure of the deodorization system is not described in detail in this specification.
[0034] Figure 3 This is a schematic diagram of a second embodiment of the mixing device according to the present invention. Figure 3 As shown, the difference from the first embodiment is that the mixing device further includes an auxiliary dust removal system 400. The auxiliary dust removal system 400 includes a second pipe 410, a second gas drive mechanism 420, a second dust collection unit 430, and a dust suction hood 440. The first end 411 of the second pipe 410 is adjacent to the feed inlet of the mixing tank 100 and positioned outside the housing 110, for example... Figure 3The feed inlet (on the side of the feed inlet) adjacent to the mixing tank 100 and positioned above the top wall 111 of the housing 110 is connected to a dust collection hood 440. The second end 412 of the second pipe 410, which is opposite to its first end 411, is in fluid communication with the second dust collection unit 430. The second gas drive mechanism 420 is disposed on the second pipe 410, preferably disposed at the second end 412 of the second pipe 410 as shown in the figure. This allows the auxiliary dust removal system 400 to draw in material dust overflowing from the feed inlet of the housing 110 through the dust collection hood 440 and flow through the second pipe 410 by means of horizontal suction when the second gas drive mechanism 420 is running, until it is drawn in and collected in the second dust collection unit 430.
[0035] Similar to the first duct 310, the first gas drive mechanism 320, and the first dust collection unit 330, the second duct 410 is made of polymer materials such as PVC. The second gas drive mechanism 420 can be a suitable model of low-power, low-noise fan, or other suction devices such as an air pump. The second dust collection unit 430 can be a flexible filter bag with a pore size between 2μm and 3μm, or any other type of flexible or rigid dust collection container. The working principle of the auxiliary dust collection system 400 is similar to that of the main dust collection system 300, and therefore will not be described again. Furthermore, the auxiliary dust collection system 400 can also be electrically connected to the control module. For example, the auxiliary dust removal system 400 can be controlled by the control module to operate only when at least one first agitator 210 is running. That is, the second gas drive mechanism 420 of the auxiliary dust removal system 400 is automatically activated when at least one first agitator 210 is running, so as to absorb dust, for example, during material feeding, and the second gas drive mechanism 420 of the auxiliary dust removal system 400 is automatically stopped when any one of the first agitators 210 is stopped. Of course, the auxiliary dust removal system 400 can also be manually turned on or off at any time as needed. For example, if a large amount of dust still overflows from the feed inlet after using the main dust removal system 300, resulting in an excessively high dust concentration in the working environment, and it is impossible to ensure that the dust concentration is controlled within the specified range, the auxiliary dust removal system 400 can be turned on to perform auxiliary dust collection.

However, it is understood that under the creative concept of this utility model, those skilled in the art can make various flexible changes and improvements to the above-disclosed concept, but all of them fall within the protection scope of this utility model.
