[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0024] Example 1

[0025] See also Figure 1 and Figure 2 As shown, a pesticide preparation mother liquid recovery device described in this embodiment includes a separation tank 20 and a separation cover 10, the separation tank 20 and the separation cover 10 are detachably connected, a feed inlet 30 is provided on the separation cover 10, a discharge port 80 is provided at the bottom of the separation tank 20, a rotating shaft 60 is provided inside the separation tank 20, and also includes a filter assembly 40, the filter assembly 40 divides the separation tank 20 into two parts, one end of the filter assembly 40 is arranged on the side of the separation tank 20, the middle part is lifted by the rotating shaft 60, and the cross section It is in a "W" shape and is relatively fixedly connected to the rotating shaft 60. It also includes a driving motor 70. The driving motor 70 can drive the rotating shaft 60 to rotate and drive the filtering component 40 to rotate inside the separation tank 20. The set filtering component 40 can filter crystals, solid residues or suspended matter to promote the recycling of mother liquor. Secondly, the cross-section of the filtering component 40 is in a "W" shape. This arrangement increases the contact area between the solution and the filtering component 40, thereby making more mother liquor filtered per unit time and improving the filtration efficiency.

[0026] Furthermore, the filter assembly 40 includes a connecting frame 401, and a flange 201 is provided at the middle and upper part of the inner wall of the separation tank 20. The connecting frame 401 is arranged on the flange 201. Specifically, a roller 406 is provided at the bottom of the connecting frame 401, and the roller 406 is actually in contact with the flange 201. The rolling contact of the roller 406 reduces the contact area, thereby reducing the friction. In addition, the roller 406 is arranged to make the driving efficiency of the rotating shaft 60 higher.

[0027] Furthermore, the filter assembly 40 also includes a connecting strip 403, a connecting plate 402 and a filter screen 404. The connecting plate 402 is connected via the connecting strip 403. Both ends of the filter screen are fixed to the connecting frame 401 and the connecting plate 402, and its bottom is supported by the connecting strip 403.

[0028] It can be understood that the connection plate 402 of the filter assembly 40 and the center of the connection frame 401 are on the same axis, and the two components arranged on the same axis can ensure good coaxiality when rotating, so that the filter residue or suspended matter will not be caused to form a tumbling due to uneven force, thereby affecting the filtration efficiency.

[0029] Furthermore, the connecting disk 402 is annular, and its four sides extend downward to form a connecting pin 405. A connecting groove is provided at the end of the rotating shaft 60, and the connecting pin 405 can be inserted into the connecting groove for connection. It also includes a fixing bolt, which can be inserted from the front of the connecting disk 402 into the interior of the rotating shaft 60, thereby relatively fixing the two. Through the connection between the connecting pin 405 and the connecting groove, a new filter assembly 40 can be quickly replaced, which is beneficial to the continuous advancement of the work, and the fixing bolt at the end can effectively limit the relative movement of the connecting disk 402 and the rotating shaft 60, thereby making the whole synchronized.

[0030] Furthermore, a plurality of support rods 50 are provided on the separation tank 20 below the filter assembly 40, and the ends of the plurality of support rods 50 are welded and arranged on a rotating bearing, and the upper and middle parts of the rotating shaft 60 are arranged inside the rotating bearing. The arrangement of the support rods 50 can provide a stable supporting force for the upper and middle parts of the rotating shaft 60, thereby making the rotating shaft 60 and the filter assembly 40 connected to the rotating shaft 60 stable as a whole, and avoiding the situation where the rotating shaft 60 deviates from the rotation center.

[0031] Furthermore, the feed port 30 is set to deviate from the lowest point of the filter component 40, and the discharge port 80 is set directly opposite to the lowest point of the filter component 40. By setting the feed port 30 to deviate from the lowest point of the filter component 40, when the mother liquor drips or enters the filter component 40, it first flows along the edge of the filter component 40 toward the bottom, thereby improving the filtration efficiency and effectively preventing the filter pores of the filter component 40 from being clogged. Secondly, when the mother liquor contacts the filter component 40, the rotating filter component 40 enlarges the contact area between the mother liquor and the filter component 40, thereby increasing the filtration area.

[0032] During the implementation process, the mother liquor to be recovered is input through the feed port 30. The mother liquor is input through the feed port 30 and contacts the filter screen due to gravity. At this time, the driving motor 70 rotates, driving the rotating shaft 60 to rotate. Since the connecting groove on the rotating shaft 60 and the connecting pin 405 on the connecting disk 402 are riveted to each other, and the axial direction is fixed by a fixing bolt, the connecting disk 402 is driven to rotate together, and the connecting bar 403 and the connecting frame 401 connected to the other end of the connecting bar 403 are driven to rotate in turn. When the mother liquor contacts the filter screen 404, The mother liquor moves downward due to gravity, and the filter screen 404 is acted upon by the rotational force, forming a larger filtering surface, thereby improving the filtering efficiency. Subsequently, the mother liquor passes through the filter screen 404, and the solids or suspended matter in the mother liquor slowly rolls to the lowest point of the "W" shape of the filter screen and settles there. After a period of time, the worker opens the separation cover 10, takes out the internal filter assembly 40, and replaces it. The old filter assembly 40 is cleaned and recycled, thereby increasing the utilization rate of the filter assembly 40 and improving its use value.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
