For the technical problem who solves the separation of impurity from the material, this application provides a material edulcoration device, and material edulcoration device includes shielding piece, support and string of a musical instrument. The shielding piece and the bracket are sequentially arranged along the moving direction of the material; the string is tensioned on the bracket, is obliquely arranged relative to the moving direction of the material and is used for shaking out/popping impurities in the material contacting with the string through self vibration; wherein the chord line has opposite front and rear ends, the front end being located at the front side of the rear end in the direction of movement, the projection of the front end being located within the projection of the shield in a plane of projection perpendicular to the direction of movement. This application can be with the separation of impurity from the material, can also avoid the material to pile up at the front end of string. As will be described in detail below.
Referring to fig. 1 and 2, fig. 1 is a sectional view of an embodiment of a material impurity removing device according to the present application, and fig. 2 is a sectional view of the material impurity removing device shown in fig. 1, in which only one string 30 is retained to more clearly show the string 30.
The material impurity removing device comprises a bracket 20 and a string 30.
The bracket 20 may include a first mounting part 21, a second mounting part 22, and a connecting rod 23. The first mounting member 20 and the second mounting member 60 are arranged at intervals in sequence in the moving direction of the material 1. In the embodiment shown, the direction of movement of the material 1 is the direction of gas flow in the figure. The connecting rod 23 extends along the moving direction of the material 1 and is fixedly connected with the first mounting part 21 and the second mounting part 22 respectively.
The string 30 is tensioned on the support 20 and is disposed obliquely with respect to the moving direction of the material 1 for shaking out/ejecting the foreign materials in the material 1 contacting the string 30 by its own vibration.
After contacting the string 30, the material 1 attaches to the string 30 and moves along the string 30. On the one hand, the relatively high density of the impurities is utilized to shake out the impurities in the process that the string 30 drives the material 1 to swing. On the other hand, the relatively hard nature of the foreign bodies is used so that the strings 30 will eject the foreign bodies from the material 1 during vibration. Thereby, separation of the material 1 from the impurities is achieved.
In particular, the chord line 30 is the portion between the first and second mounting elements 21, 22. A flexible string may be used to wind back and forth over the first and second mounting elements 21, 22 to form a plurality of strings 30.
Referring to fig. 3, fig. 3 is a schematic three-dimensional structure diagram of the first mounting member 21 of the material impurity removing device shown in fig. 1.
The first mounting member 21 is provided with a plurality of threading holes 211 therethrough. The flexible rope is threaded in two adjacent threading holes 211 and wound on the solid part between the two adjacent threading holes 211 so as to be connected with the first mounting part 21. Wherein the segment of the flexible cord wound around the solid portion does not belong to the string 30.
In other embodiments, the specific structure of the flexible rope connected to the first mounting member 21 may be as follows:
the flexible cord is connected to the first mounting element 21 by means of a knot. The segments wound around the first mounting element 21 to effect the knot do not belong to the string 30.
The flexible cord is pressed against the first mounting element 21 by a screw. The portion of the flexible cord that is pressed against by the screw does not belong to the string 30.
The string 30 has opposite leading and trailing ends 30a, 30 b. Specifically, the string 30 is the portion between the first and second mounting elements 21, 22, and the contact points of the string 30 with the first and second mounting elements 21, 22 are the front and rear ends 30a, 30b, respectively, i.e. the contact point of the string 30 with the first mounting element 21 is the front end 30a and the contact point of the string 30 with the second mounting element 22 is the rear end 30 b. The front end 30a is located forward of the rear end 30b in the direction of movement of the material 1. Without obstruction, material 1 passes first through front end 30a and then through back end 30 b. At the front end 30a, a gap may exist between the string 30 and the first mounting element 21, for example, in the present embodiment, a gap may exist between the string 30 and the inner wall surface of the threading hole 211. In addition, when there are a plurality of strings 30, a gap may exist between the plurality of strings 30 at the tip 30 a. The material 1 is easily accumulated at the front end 30a of the string 30 and is not easily cleaned.
Referring to fig. 4, fig. 4 is an enlarged view of a partial view a in fig. 1.
In order to prevent the material 1 from being accumulated at the front end 30a of the string 30, the material impurity removing device further comprises a shielding piece 70, and the shielding piece 70 and the bracket 20 are sequentially arranged along the moving direction of the material 1. Specifically, the shield 70 is adjacent the first mounting element 21 and is located on the side of the first mounting element 20 facing away from the second mounting element 60. The projection of the leading end 30a of the chord line 30 is located within the projection of the shutter 70 in a plane of projection perpendicular to the direction of movement. During the movement of the material 1, it passes first through the blanking member 70 and then through the leading end 30a of the string 30. The shield 70 can shield the leading end 30a of the string 30 from the accumulation of the material 1 thereat.
To drive the material 1 to move, the material impurity removing device may include an airflow generator (not shown) for generating an airflow to drive the material 1 to move. In particular, the air flow generator may be a fan or a high pressure air source, blowing air in the direction of the arrows in fig. 1. The airflow generator can also be a negative pressure source which can also drive the air to flow, thereby generating airflow.
In some cases, the air flow generator may not be provided, and the material 1 falls freely under the action of gravity. In this case, the string 30 is disposed obliquely to the direction of gravity.
In some cases, the material 1 may be moved by the combined action of the air flow generator and gravity.
In the embodiment shown in fig. 1, an airflow generator is used to move the material 1.
The material 1 may be a semi-finished product in the process of moxa production, which is gathered/scooped up, wrapped or stained with impurities (e.g. stems of mugwort leaves). The moxa has the characteristic of being soft, and is suspended in the air and moves (flutters) along with the air flow under the driving of the air flow. The material 1 may also be another material, such as cotton.
After the shield 70 is provided, the material 1 may be accumulated at the shield 70. In some embodiments, the shield 70 may be provided as a removable structure, and when the material 1 is deposited, the shield 70 is removed to clean the material 1. In some embodiments, the shield 70 is provided with a flat, unbroken surface to further facilitate cleaning of the material 1.
Further, in order to reduce or even avoid the accumulation of material 1 at the shield 70, the surface 71 of the shield 70 on the side facing away from the holder 20 is optionally smoothly transitioned. In particular, the roughness value of surface 71 may be less than 1.6 microns. Since the surface 71 is smooth, the material 1 is difficult to stay on the surface 71.
Optionally, the surface 71 is a conical surface. In this shape, the top area of the surface 71 is extremely small, and the material 1 cannot be accumulated.
Optionally, the taper angle of the surface 71 (conical surface) is 40 ° to 60 °.
Alternatively, the axis of the surface 71 (conical surface) is parallel to the direction of movement of the material 1.
Optionally, a shield 70 is connected to the bracket 20 and is adjustable in position in the direction of movement. Specifically, the shield 70 is threadedly coupled to the first mounting member 21, and the shield 70 can be moved toward or away from the first mounting member 21 by screwing the shield 70. During use, the optimal shielding effect is ensured by adjusting the position of the shielding member 70 in the moving direction.
Optionally, the blinder 70 has a cavity 72 that opens toward the first mounting member 20, the cavity 72 housing the leading end 30a of the string 30. Thus, the material 1 does not pass directly through the front end 30a, and accumulation of the material 1 at this position is avoided.
Alternatively, the projection of the rear end 30b of the chord line 30 is outside the projection of the shield 70 in a plane of projection perpendicular to the direction of movement. The blanking member 70 does not shield the entire string 30 so that the string 30 can be separated by portions not shielded by the blanking member 70.
In a projection plane perpendicular to the moving direction, a projection of a partial segment 30c of the string 30 from the leading end 30a of the string 30 is located within a projection of the shutter 70. The length of the part of the string section 30c in the string 30 is too large, which reduces the material separation efficiency. For this reason, the length of the partial string section 30c is not more than 0.4 times the length of the string. Further, the length of the partial string section 30c is not more than 0.1 times the length of the string.
The material dislodging apparatus may further comprise a vibration generator 40, the vibration generator 40 being adapted to drive the string 30 to vibrate. For example, the vibration generator 40 generates a standing wave on the string 30. The vibration generator 40 is disposed on the string 30, and generates vibration when being blown by the air flow, so as to drive the string 30 to vibrate.
In other embodiments, the vibration generator 40 may also be an eccentric motor, which is optionally prior art. The eccentric motor includes a motor and a rotating body. The motor is provided on the string 30, the rotating body is attached to the rotating shaft of the motor, and the center of gravity of the rotating body is displaced from the rotating shaft and vibrates by the rotation of the rotating body.
In other embodiments, the vibration generator 40 may also be a deflector rod that is capable of deflecting the string 30 such that the string 30 vibrates.
The specific structure of the vibration generator 40 is not limited, and the string 30 may be driven to vibrate.
In order to improve the working efficiency of the material impurity removing device, the number of the strings 30 can be multiple, and the multiple strings 30 are distributed in a radial shape around a reference axis L1, wherein the reference axis L1 is parallel to the airflow direction.
The material impurity removing device can further comprise a cylinder 10, the cylinder 10 is provided with an inlet 11 and an outlet 12, wherein a chord line 30 is arranged in the cylinder 10, and the airflow generator is used for generating airflow in the cylinder 10, and the airflow is used for driving the material 1 to flow into the cylinder 10 from the inlet 11 and flow out of the cylinder 10 from the outlet 12.
In particular, the cylinder 10 extends along a predetermined path, so that the material 1 is conveyed along the predetermined path under the guidance of the cylinder 10. By providing the cylinder 10, a moving path of the material 1 can be defined.
The impurities are separated from the agglomerated/scooped material 1, and after separation, the impurities and the plurality of agglomerated/scooped materials 1 are still in a mixed state, and then the impurities and the plurality of agglomerated/scooped materials 1 are separated in the subsequent process. Specifically, in an application scenario, the inlet 11 of the cylinder 10 communicates with a pulverizing device (not shown), and the outlet 12 of the cylinder 10 communicates with a cyclone separation device (not shown). The crushing device is used for crushing the raw materials to form the material 1. After the material 1 enters the cylinder 10, impurities are separated from the material 1 through the string 30, and the material 1 and the impurities are separated and enter the cyclone separation device together with the airflow. The cyclone separation device utilizes the centrifugal force generated when rotating at high speed, so that the impurities are separated from a plurality of agglomerated/scooped materials 1 and are left in the cyclone separation device, and the materials 1 enter the subsequent equipment along with the airflow.
The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
