Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stirring equipment, in particular to a dust removal mixer. Background Art
[0002] A mixer is used to mix two or more materials together to achieve uniform distribution. Common mixers include horizontal plowshare mixers, ribbon mixers, one-dimensional mixers, two-dimensional mixers, and three-dimensional mixers. Trough mixers achieve mixing through stirring in a single direction, that is, the materials are pushed in one direction by the agitator to mix, so they are one-dimensional mixers and are suitable for mixing granules, powders, and some sticky materials, such as flour, powdered sugar, protein powder, etc.
[0003] However, after mixing the materials, the trough mixer needs to take out the materials in the mixer. When the cover is opened, some material dust will still float in the mixer cavity. These material dusts will still escape and drift into the air, which may also affect the operators and the environment. Many existing trough mixers are equipped with separate dust prevention devices, such as dust covers, dust cloths, etc., to prevent dust from flying. Some advanced trough mixers also adopt a closed design, so that the entire mixing process is carried out in a relatively closed environment, so as to better prevent dust from flying. Although these devices can prevent material dust from drifting into the air, material dust will enter between the mixing trough and the dust prevention device. After a long period of work, the material dust needs to be cleaned separately. Utility Model Content

[0006] Furthermore, the dust removal chamber is located at the air inlet end of the circulating fan.
[0007] Furthermore, a dust removing component is provided in the dust removing chamber, the dust removing component is located on the air flow channel, and the dust removing component is fixed in the dust removing chamber.
[0008] Furthermore, a collecting device is provided in the dust removal chamber, and the collecting device is located at the bottom of the dust removal component, the top surface of the collecting device is lower than the bottom of the air inlet end, and the orthographic projection of the dust removal component is located in the collecting device.

[0024] The following is combined with Figure 1-6 The embodiments of the present utility model are described in detail.
[0025] Example 1
[0026] The utility model relates to a dust removal mixer, comprising a mixing tank 1 and a cover plate 2 covering the mixing tank 1, wherein the cover plate 2 is provided with an air inlet 21 and an air outlet 22 on one side facing the mixing tank 1; the air inlet 21 is connected to the air outlet end of a circulating fan 3 through a first pipe 23, and the air outlet 22 is connected to the air inlet end of the circulating fan 3 through a second pipe 24, so as to form an air flow channel connected to the mixing tank 1; a dust removal chamber 4 is provided on the air flow channel, so as to remove material dust in the air flow channel.
[0027] Specifically, Figure 1 and Figure 2As shown, the dustproof tank mixer in the present application is U-shaped, including two base boxes located on the left and right sides and a mixing tank 1 located between the two base boxes. The mixing tank 1 has a material input port and a material output port, where the material input port and the material output port are the same, both of which are openings of the U-shaped mixing tank 1, and the cover plate 2 is covered on the opening. A fixing block (not shown in the figure) is arranged between the mixing tank 1 and the base box on both sides facing the base box, which is used to fix the distance between the mixing tank 1 and the base box. A stirring shaft is installed in the mixing tank 1, and the stirring shaft passes through both ends of the mixing tank 1 in the axial direction, and is fixedly connected to the bearing of the mixing tank 1. Similarly, the two ends of the stirring shaft extend to the side walls of the base box on both sides until the stirring shaft is fixedly connected to the bearing of the side wall of the base box. A stirring paddle is installed on the stirring shaft in the mixing tank 1, and the stirring paddle can be a single paddle or a double paddle, both of which can achieve stirring of the materials in the mixing tank 1. In the present application, the stirring paddle is preferably a single-paddle stirring paddle, and the stirring paddle rotates coaxially with the stirring shaft for stirring. A driving device, such as a motor, for driving the stirring shaft is installed in the base box on the left, while a control device for controlling the operation of the entire mixer is installed in the base box on the right.
[0028] During the mixing process of the mixer, for example, Chinese medicine, Chinese medicine dust will be generated in the mixing chamber in the upper layer, i.e., near the cover plate 2. After the Chinese medicine is mixed, the dust will float into the air when the cover plate 2 is opened, which may cause an impact on the operator and the environment. Therefore, in order to remove the Chinese medicine dust, Figure 3As shown, holes are provided on the cover plate 2, which are respectively an air inlet 21 and an air outlet 22, and the air inlet 21 and the air outlet 22 are respectively connected to the air inlet end and the air outlet end of the circulating fan 3 through the pipeline 25, so that an air flow loop is formed in the mixing tank 1. On the basis of this loop, a dust removal chamber 4 is set at the air inlet end of the circulating fan 3, and the dust removal chamber 4 can be set at the air inlet end of the circulating fan 3 or at the air outlet end of the circulating fan 3, and dust removal can be achieved. For example, when the dust removal chamber 4 is set at the air inlet end, when the circulating fan 3 is started, the Chinese medicine dust floating on the upper layer is extracted from the air outlet 22, and after dust removal in the dust removal chamber 4, the clean gas enters the mixing chamber from the air inlet 21. That is, under the action of the circulating fan 3, the airflow in the mixer cavity can realize the reciprocating cycle of "inner cavity of the mixer - air outlet 22 - second pipe 24 - dust removal chamber 4 - circulating fan 3 - first pipe 23 - air inlet 21 - inner cavity of the mixer". In this process, the Chinese medicine dust realizes "inner cavity of the mixer - air outlet 22 - second pipe 24 - dust removal chamber 4 - circulating fan 3", and then the dust is removed by the dust removal chamber 4. When the dust removal chamber 4 is set at the air outlet end, after the circulating fan 3 is started, the Chinese medicine dust floating on the upper layer is extracted from the air outlet 22, and after the circulating fan 3 and the dust removal chamber 4 are dusted, the clean gas enters the mixing cavity from the air inlet 21. That is, under the action of the circulating fan 3, the air flow in the mixer cavity can realize a reciprocating cycle of "inner cavity of the mixer - air outlet 22 - second pipe 24 - circulating fan 3 - dust removal chamber 4 - first pipe 23 - air inlet 21 - inner cavity of the mixer". In this process, the Chinese medicine dust realizes "inner cavity of the mixer - air outlet 22 - second pipe 24 - circulating fan 3 - dust removal chamber 4", and then the dust is removed by the dust removal chamber 4.
[0029] Example 2
[0030] Specifically, in order to improve the working efficiency of the fan, such as Figure 3-Figure 5 As shown, the dust removal chamber 4 is arranged at the air inlet end of the circulation fan 3.
[0031] Example 3
[0032] This embodiment is an improvement made on the basis of Embodiment 2, and the difference lies in that a dust removing component 41 is provided in the dust removing chamber 4, the dust removing component 41 is located on the air flow channel, and the dust removing component 41 is fixed in the dust removing chamber 4.
[0033] Specifically, as shown in the figure, a dust removal member such as a filter or a dust bag is provided in the dust removal chamber, and the dust removal member is located on the air flow channel, that is, the dust removal side of the dust removal member 41 faces the second pipe 24 and is parallel to it; the dust removal member 41 faces the air inlet end opposite to the dust removal side. Moreover, the dust removal member 41 is located in the dust removal chamber 4 away from the second pipe 24, that is, there is a certain distance between the dust removal member and the second pipe, so that the Chinese medicine dust can be filtered in the dust removal chamber 4.
[0034] The dust removal member 41 may have its edges connected to the top wall, the bottom wall and the inner walls on opposite sides of the dust removal chamber 4 respectively, or may have only its upper and lower ends fixed to the top wall and the bottom wall of the dust removal chamber 4 .
[0035] Example 4
[0036] This embodiment is an improvement on Embodiment 3, the difference being that a collecting device 5 is further provided in the dust removal chamber 4, the collecting device 5 is located at the bottom of the dust removal member 41, the top surface of the collecting device 5 is lower than the bottom of the air inlet end, and the orthographic projection of the dust removal member 41 is located in the collecting device 5.
[0037] Specifically, in order to collect the Chinese medicine dust on the dust removal element 41 at the air inlet end, Figure 6 As shown, a collecting device 5 is also provided at the bottom of the dust removal member 41, and the collecting device 5 here can be fixed in the dust removal chamber 4 by bolts. The collecting device 5 can be in various shapes such as rectangle, square, circle, etc., as long as the positive projection of the dust removal member 41 is located in the collecting device. When there is a lot of Chinese medicine dust on the dust removal member 41, the Chinese medicine dust is shaken off from the dust removal member 41 during the operation of the circulating fan 3 and falls into the collecting device 5, such as a collecting frame, which further improves the dust removal effect.
[0038] Example 5
[0039] This embodiment is an improvement made on the basis of Embodiment 2, and the difference lies in that the circulation fan 3 is located on the top surface of the cover plate 2 .
[0040] Specifically, Figure 3-Figure 5 As shown, in order to reduce the flow path of the circulation channel outside the cavity, the circulation fan 3 is installed on the top surface of the cover plate 2, that is, the top surface of the top plate 23. The advantage of this design is that after the gas is extracted from the cavity and enters the circulation fan 3 through the pipeline 25, the shorter the path, the higher its working efficiency and the smaller the energy loss. For example, when the path is long, the time for the gas with Chinese medicine dust to flow to the first dust removal component 4 at the entrance end of the circulation fan 3 is longer. Under the condition of the same flow rate, the shorter the path, the shorter the time consumption and the less energy loss, and vice versa.
[0041] Example 6
[0042] This embodiment is an improvement made on the basis of the embodiment 1, and the difference is that the cover plate 2 further comprises a shell 6, the inner wall of the shell 6 abuts against the outer wall of the cover plate 2, and is detachably connected to the cover plate 2. A handle 7 is provided on the top of the shell 6, and the handle is located on the top surface of the shell 6.
[0043] Specifically, in order to protect the circulation fan 3, the first pipeline 23 and the second pipeline 24, as shown in FIG. Figure 4 and Figure 5 As shown, a shell 6 is further provided outside the cover plate 2, the cover plate 2 is wrapped in the shell 6, and a handle 9 is provided on the top of the shell 6 for easy handling of the cover plate 2. Here, the connection between the cover plate 2 and the shell 6 can be a snap connection or a bolt connection, both of which can achieve the function of protecting the circulation fan 3 and the first pipe 23 and the second pipe 24.
[0044] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
