DETAILED DESCRIPTION

[0024] 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 technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] See also Figures 1 to 4 In Example 1 of the utility model, a structural diagram of a liquid preparation tank for preparing liquid medicine provided by the utility model embodiment includes: a tank body 10, on which a feeding port 101 and a discharging port 102 are provided; a stirring component 20, which is rotatably arranged inside the tank body 10; a de-dusting component 30, which is arranged below the feeding port 101; the de-dusting component 30 includes a mounting frame 301 which is rotatably and slidably arranged inside the tank body 10, a de-dusting frame 302 is arranged inside the mounting frame 301, and a de-dusting net 304 is arranged inside the de-dusting frame 302; a transmission component arranged between the stirring component 20 and the de-dusting component 30, which is used to drive the de-dusting component 30 to rotate and jump when adding and removing de-dusting.

[0027] The utility model adds protease raw materials into the tank body 10 through the feeding port 101, and the impurity removing component 30 removes impurities from the protease raw materials. At the same time, the stirring component 20 rotates and drives the impurity removing component 30 to rotate and jump, thereby improving the impurity removing efficiency. The utility model solves the problem of the need to remove impurities from the raw materials by setting the impurity removing component 30, and at the same time, the impurity removing component 30 can rotate and jump, thereby improving the impurity removing efficiency.

[0028] like Figure 1As shown, as a preferred embodiment of the utility model, the stirring component 20 includes a stirring shaft 201 rotatably mounted on the tank body 10 and a plurality of stirring blades 203 arranged in an array on the stirring shaft 201, and the stirring blades 203 are welded and arranged on the stirring shaft 201. In order to drive the stirring shaft 201 to rotate, a driving motor 202 is also provided on the tank body 10, and the driving motor 202 is transmission-connected with the stirring shaft 201. The driving motor 202 can be connected to the stirring shaft 201 through a gear or a coupling. In this way, the stirring shaft 201 drives the stirring blades 203 to rotate to provide power.

[0029] In order to realize the rotation of the mounting frame 301 and the elastic arrangement of the mounting frame 301 up and down inside the tank body 10, at least two elastic telescopic rods 306 are arranged at the bottom of the mounting frame 301, and the elastic telescopic rods 306 are fixedly mounted on the mounting ring 307, and the mounting ring 307 is rotatably arranged on the support seat 308, and the support seat 308 is fixedly mounted inside the tank body 10. The elastic telescopic rods 306 are fixedly mounted on the bottom of the mounting frame 301. The support seat 308 can be fixedly mounted inside the tank body 10 by bolts.

[0030] The transmission component includes a transmission telescopic rod 204 symmetrically arranged on the stirring shaft 201 and a matching block 305 fixedly installed at the bottom of the installation frame 301. A plurality of driving grooves 3051 are arranged in a circumferential array on the matching block 305. The transmission telescopic rod 204 is used to be inserted into the driving groove 3051 when the installation frame 301 is lowered. Specifically, when the protease raw material is added to the feeding port 101, the installation frame 301 compresses the elastic telescopic rod 306, the installation frame 301 drives the matching block 305 to descend, the transmission telescopic rod 204 hits the matching block 305, and at the same time, the driving motor 202 drives the stirring shaft 201 to rotate, the stirring shaft 201 drives the transmission telescopic rod 204 to rotate, the transmission telescopic rod 204 cooperates with the driving groove 3051, and drives the installation frame 301 to rotate.

[0031] like Figure 2As shown, as a preferred embodiment of the utility model, in order to make the installation frame 301 jump up and down during the rotation process, no less than two interference rods 3012 are arranged in an array on the outer side of the installation frame 301, and a support ring 3013 is sleeved on the outer side of the installation frame 301, and the support ring 3013 is fixedly installed inside the tank body 10; a plurality of interference protrusions 3014 are arranged in an array on the support ring 3013, and the interference protrusions 3014 are arranged on the track of the interference rod 3012. The interference rods 3012 are arranged in two, and the interference protrusions 3014 are arranged in an even number. Specifically, when the installation frame 301 rotates, the interference rods 3012 are driven to rotate, and the interference rods 3012 are in contact with the interference protrusions 3014 during the rotation process, so that the installation frame 301 slides up and down. If there are many attachments on the impurity removal net 304, which affects the impurity removal efficiency, the installation frame 301 is driven by gravity to drop, and the overlapping height of the contact rod 3012 and the contact protrusion 3014 vibrates, increasing the height of the installation frame 301 jumping, thus increasing the impurity removal efficiency; in this way, the efficiency can be automatically adjusted according to the impurity removal process. The impurity removal net 304 is an ultrafiltration impurity removal membrane with a molecular weight of 30,000.

[0032] In order to facilitate the replacement of the impurity removal net 304, the impurity removal frame 302 is slidably arranged inside the installation frame 301.

[0033] A plurality of guide slide blocks 3021 are arranged outside the impurity removal frame 302 , and the guide slide blocks 3021 are slidably arranged in the slide grooves 3011 inside the installation frame 301 , so that the impurity removal frame 302 can be slid up and down in the installation frame 301 .

[0034] like Figure 2 As shown, as a preferred embodiment of the utility model, the impurity removal net 304 is a barrel-shaped structure with an opening at the top. A pressure ring 303 is installed at the top opening of the impurity removal frame 302 to fix the bottom of the impurity removal net 304, so that the impurity removal net 304 is fixed. When the impurity removal net 304 needs to be cleaned, the pressure ring 303 can be removed from the impurity removal frame 302. The pressure ring 303 can be fixed on the impurity removal frame 302 by screw thread or by buckle.

[0035] In order to facilitate the removal of the mounting frame 301 from the tank body 10, the tank body 10 includes a lower tank body 11 and an upper tank body 12, wherein the lower tank body 11 is detachably arranged on the upper tank body 12. The lower tank body 11 can be connected to the upper tank body 12 by bolts. The stirring shaft 201 and the discharge port 102 are arranged on the lower tank body 11, and the discharge port 102 is arranged on the upper tank body 12.

[0036] The working principle of the utility model is:

[0037] The protease raw material is added into the tank body 10 through the feeding port 101, and the driving motor 202 is driven to rotate, so as to drive the stirring shaft 201 and the stirring blade 203 to rotate. The stirring shaft 201 drives the transmission telescopic rod 204 to drive the matching block 305 and the installation frame 301 to rotate, and the installation frame 301 drives the resistance rod 3012 to rotate. The resistance rod 3012 resists 3104 during the rotation, so that the installation frame 301 slides up and down, so that the impurity removal net 304 jumps up and down and rotates when removing impurities from the protease raw material, and the rotation utilizes the centrifugal force to improve the impurity removal efficiency, and the up and down jumping avoids clogging; if there are many attachments on the impurity removal net 304, which affects the impurity removal efficiency, the installation frame 301 descends under the drive of gravity at this time, and the overlapping height of the resistance rod 3012 and the resistance protrusion 3014 vibrates, so as to increase the jumping height of the installation frame 301, thereby increasing the impurity removal efficiency; in this way, the efficiency can be automatically adjusted according to the impurity removal process.
