Description

Technical Field

[0001] This utility model belongs to the technical field of raw material pharmaceutical processing, and specifically relates to a filtration device. Background Technology

[0002] Active pharmaceutical ingredients (APIs) refer to the raw materials used in the production of various formulations. They are the active ingredients in these formulations and are substances prepared through chemical synthesis, plant extraction, or biotechnology, in the form of powders, crystals, or extracts used for medicinal purposes, but which patients cannot directly ingest. During the preparation of APIs, filtration is required to remove small particulate impurities.

[0003] While existing filtration devices can meet the basic requirements for filtering raw pharmaceutical materials, they typically only filter the materials by shaking the filter structure. During the filtration process, the agitation of the raw materials is insufficient, and impurities cannot be effectively removed from the materials. This affects the filtration efficiency and fails to fully meet user needs. Utility Model Content

[0004] In view of this, the present invention addresses the shortcomings of the prior art by providing a filtration device that not only meets the basic requirements for filtering and removing impurities from raw pharmaceutical materials, but also directly and thoroughly agitates the raw pharmaceutical materials, thereby completely separating the raw pharmaceutical materials from the impurities and thus effectively filtering the impurities.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a filtration device, including a base, a processing box with a conical lower end and an open top is provided on the base via a support rod, a filter tank with an open top is slidably provided inside the processing box in the left-right direction, a stirring shaft is rotatably provided through the filter tank, a stirring blade is provided on the stirring shaft for stirring the raw materials in the filter tank, a spiral rod is also provided on the outer end of the stirring shaft, a spiral cylinder is provided on the inner side wall of the processing box and screwed to the spiral rod, a discharge pipe is also provided at the bottom of the filter tank, and a control valve is provided on the discharge pipe.

[0006] As a further improvement of this invention, the lower half of the filter tank is semi-cylindrical. The raw material can fall into the lower middle part of the filter tank under the action of gravity, thereby being fully agitated by the stirring shaft and stirring blades.

[0007] As a further improvement of this utility model, connecting grooves are provided on the inner walls of the front and rear sides of the processing box along the left and right directions, and connecting slide plates are provided on the side walls of the filter tank, which are slidably connected to the connecting grooves. Through the sliding cooperation of the connecting grooves and the connecting slide plates, the filter tank and the processing box can be slidably connected.

[0008] As a further improvement of this utility model, a horizontal plate is provided on the inner wall of the other side of the processing box. A mounting shaft is rotatably mounted on the horizontal plate, and a turntable is mounted on the mounting shaft. A connecting rod is eccentrically mounted on the turntable. A horizontal bar is provided on the side wall of the filter tank, and the other end of the horizontal bar is rotatably connected to the connecting rod. Through the cooperation of the horizontal plate, mounting shaft, turntable, connecting rod, and horizontal bar, the filter tank can be driven to slide back and forth.

[0009] As a further improvement of this utility model, a drive motor is provided on the horizontal plate, a driving gear is provided on the output shaft of the drive motor, and a driven gear meshing with the driving gear is provided on the mounting shaft. The drive motor, driving gear, and driven gear enable rotational drive of the mounting shaft.

[0010] As a further improvement of this utility model, a reinforcing rod is also provided between the horizontal plate and the side wall of the processing box. The reinforcing rod enhances the stability between the horizontal plate and the processing box.

[0011] As a further improvement of this utility model, an extension plate is also provided at the bottom side of the base, and anchor bolts for connecting to the ground are provided on the extension plate. The extension plate and anchor bolts can prevent the device from easily shifting or tipping over during operation.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, by simply driving the filter tank to slide back and forth in opposite directions, the raw material can be shaken and thus screened. During the back-and-forth sliding of the filter tank, the screw rod will move back and forth relative to the screw cylinder, and the screw cylinder will drive the screw rod to rotate, thereby driving the rotation of the stirring shaft and stirring blades. This allows the raw material to be stirred while it is being shaken and screened, thus enabling more thorough and efficient screening of the raw material.

[0014] Secondly, the lower half of the filter tank is semi-cylindrical. The raw material can fall into the lower part of the filter tank under the action of gravity, so that it can be fully agitated by the stirring shaft and stirring blades. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 2 As shown, a filtration device includes a base 101, a support rod 102 fixedly connected to the base 101, and a processing box 103 with a conical lower end and an open top fixedly connected to the support rod 102. A discharge port 112 is provided at the bottom of the processing box 103. A filter tank 104 with an open top is slidably arranged inside the processing box 103 in a left-right direction. A stirring shaft 105 is rotatably arranged through the center of the filter tank 104. First bearings 106 are provided on the outer walls of the left and right ends of the filter tank 104. The outer ring of the first bearing 106 is connected to the outer wall of the filter tank 104. The inner ring is connected to the outer wall of the stirring shaft 105. The left end of the stirring shaft 105 extends to the outer side of the filter tank 104. The left end of the filter tank 104 is provided with a through hole that is rotatably connected to the stirring shaft 105. A stirring blade 107 for stirring the raw materials in the filter tank 104 is fixedly connected to the stirring shaft 105. A screw rod 108 is also fixedly connected to the left end of the stirring shaft 105. A screw cylinder 109 that is screwed to the screw rod 108 is fixedly connected to the inner wall of the processing box 103. A discharge pipe 110 is also installed at the bottom of the filter tank 104, and a control valve 111 is provided on the discharge pipe 110. The height of the filter hole area on the filter tank 104 is lower than that of the stirring shaft 105, which can effectively prevent impurities from falling onto the stirring shaft 105 and the screw rod 108.

[0022] like Figure 3 As shown, the lower half of the filter tank 104 is semi-cylindrical.

[0023] Workers add the raw pharmaceutical material requiring filtration and impurity removal into the filter tank 104 through the top opening of the processing box 103. Under gravity, the raw material falls into the lower half (semi-cylindrical area) of the filter tank 104. The filter tank 104 is then driven to slide back and forth, shaking the raw material for agitation and sieving. During this back-and-forth movement, the screw rod 108 moves relative to the screw cylinder 109, which in turn drives the screw rod 108 to rotate, thereby driving the rotation of the stirring shaft 105 and the stirring blades 107. This simultaneous shaking and sieving process agitates the raw material, resulting in more thorough and efficient filtration. Because the lower half of the filter tank 104 is semi-cylindrical, the raw material falls into the lower middle part of the filter tank 104 under gravity, ensuring thorough agitation by the stirring shaft 105 and the stirring blades 107.

[0024] After being shaken, screened, and stirred, impurities in the raw material will pass through the filter holes of the filter tank 104 and then fall into the processing box 103. They will then leave the processing box 103 through the discharge port 112. The raw material will remain in the filter tank 104 because it cannot pass through the filter holes of the filter tank 104.

[0025] After a period of time, simply open the control valve 111, and the raw material will leave the filter tank 104 through the discharge pipe 110, then fall into the processing box 103, and then leave the processing box 103 through the discharge port 112.

[0026] According to another embodiment of the present invention, such as Figure 1 , 3 As shown, a connecting groove 201 is fixedly connected to the inner wall of the front and rear sides of the processing box 103 along the left and right direction, and a connecting slide plate 202 that is slidably connected to the connecting groove 201 is fixedly connected to the side wall of the filter tank 104.

[0027] like Figure 1 , 3As shown, a horizontal plate 203 is fixedly connected to the inner wall of the other side of the processing tank 103. An installation shaft 204 is rotatably mounted on the horizontal plate 203. A second bearing 205 is provided on the horizontal plate 203. The outer ring of the second bearing 205 is connected to the top wall of the horizontal plate 203, and the inner ring of the second bearing 205 is connected to the outer wall of the installation shaft 204. A turntable 206 is fixedly connected to the installation shaft 204. A connecting rod 207 is eccentrically rotatably mounted on the turntable 206 via a first rotating shaft 209. The first rotating shaft 209 is eccentrically fixed to the turntable 206. One end of the connecting rod 207 is rotatably connected to the first rotating shaft 209. A horizontal bar 208 is provided on the side wall of the filter tank 104. The other end of the horizontal bar 208 and the connecting rod 207 are rotatably connected via a second rotating shaft 210. The second rotating shaft 210 is fixed to the horizontal bar 208, and the other end of the connecting rod 207 is rotatably connected to the second rotating shaft 210.

[0028] like Figure 3 As shown, a drive motor 211 is provided on the horizontal plate 203. The fixed end of the drive motor 211 is connected to the bottom of the horizontal plate 203. A drive gear 212 is fixedly connected to the output shaft of the drive motor 211, and a driven gear 213 that meshes with the drive gear 212 is fixedly connected to the mounting shaft 204.

[0029] By simply starting the drive motor 211, the mounting shaft 204 can be rotated through the transmission of the drive gear 212 and the driven gear 213, thereby driving the turntable 206 to rotate. The connecting rod 207 moves accordingly, and under the sliding engagement of the connecting slide plate 202 and the connecting groove 201, it pushes the crossbar 208 and the filter tank 104 to slide back and forth.

[0030] According to another embodiment of the present invention, such as Figure 2 As shown, a reinforcing rod 214 is welded between the horizontal plate 203 and the side wall of the processing box 103. The reinforcing rod 214 enhances the stability between the horizontal plate 203 and the processing box 103.

[0031] According to another embodiment of the present invention, such as Figure 1 As shown, an extension plate 301 is also fixedly connected to the bottom side of the base 101. Anchor bolts for connecting to the ground are also provided through the extension plate 301, and mounting holes for engaging with the anchor bolts are provided on the extension plate 301. By simply driving the anchor bolts through the extension plate 301 and connecting them to the ground, the device can be effectively prevented from easily shifting or tipping over during operation.

[0032] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
