[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] like Figure 1 As shown, an automatic screening and filtration device for preparing benzyl chloride includes a housing 1, with a cover plate 2 on the upper part of the housing and a feed inlet on the cover plate. The housing is preferably cuboid in shape, and a bottom plate is also provided at the bottom of the housing. Inside the housing are a first screening structure 3 and a second screening structure 4 distributed vertically. The first screening structure includes a frame with a filter screen on it. One end of the frame is hinged to the housing, and the other end is connected to a reciprocating structure via a connecting line 5. The second screening structure includes a second frame with a second filter screen on it. One end of the second frame is hinged to the housing, and the other end is connected to the reciprocating structure via a second connecting line 6. The housing has three sets of outlets, located at the hinge of the first filter screen, the hinge of the second filter screen, and one end of the bottom plate, respectively.
[0017] Furthermore, the upper part of the housing is provided with an outward protrusion 7, which is located above the first screening structure, and the reciprocating structure is arranged at the protrusion. The reciprocating structure includes a connecting plate 8, which is rotatably connected to a fixed plate 9, and the fixed plate is fixedly connected to the protrusion. The protrusion is also rotatably connected to a cam 10, which is used to resist the reciprocating motion of the connecting plate.
[0018] The housing is also equipped with two sets of support plates 12, which are used to support the frame and the second frame, respectively. Springs (not shown in the figure) are provided on the support plates. Fixing holes are provided on the frame for the second connecting wire to pass through.
[0019] The housing may be equipped with a guide plate 11, the cross-sectional area of the lower end face of the guide plate being smaller than that of the upper end face. The area of the screen mesh is larger than the cross-sectional area of the lower end face of the guide plate.
[0020] The working principle of this utility model is as follows: benzyl chloride enters the shell for sieving, and after passing through the guide plate, it is placed on the screen of the first sieving structure. Then, the reciprocating structure works, and the screen moves back and forth. With the help of springs, the sieving efficiency is improved, and larger impurities are sieved. Then, benzyl chloride enters the second sieving structure, and smaller impurities fall onto the bottom plate. Overall, the larger and smaller impurities in the benzyl chloride are sieved to ensure the effect. At the same time, it reduces clogging, facilitates collection, and improves the overall working efficiency.
