[0026] 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.

[0027] The utility model provides a technical solution:

[0028] See also Figures 1 to 4 A waste residue separation device for chemical machinery comprises a feed bin 1, a screening bin 2 which is interconnected with the feed bin 1 is arranged below the feed bin 1, a detachable screen assembly 5 is installed inside the screening bin 2, a discharge port 3 which is opened on the surface of the screening bin 2 is arranged at the front end of the screen assembly 5, and a waste residue component feeding mechanism 4 is arranged at the connection between the feed bin 1 and the screening bin 2;

[0029] The screen assembly 5 includes a front end support plate 501 and a rear end support plate 503 fixed on the inner wall of the screening bin 2, the rear end support plate 503 is located on the rear inner wall of the screening bin 2, and the front end support plate 501 is located on the front inner wall of the screening bin 2, the front end support plate 501 is located below the discharge port 3, a screen plate body 502 is arranged on the top of the front end support plate 501 and the rear end support plate 503, and a support spring 504 is installed between the screen plate body 502 and the rear end support plate 503, an installation groove 505 is opened at the connection between the screen plate body 502 and the rear end of the screening bin 2, and the rear end of the screen plate body 502 is fixedly connected to a limiting plate 506.

[0030] The two ends of the support spring 504 are respectively connected to the screen plate body 502 and the rear end support plate 503, and the support spring 504 is movably abutted against the bottom of the screen plate body 502, and the lower end of the support spring 504 is fixed to the top of the rear end support plate 503. The screening bins 2 are provided with three groups, and the screening bins 2 are provided one by one with the screen mesh assembly 5, and the rear end support plate 503 is higher than the front end support plate 501.

[0031] By adopting the above technical scheme, a handle is set at the rear end of the limit plate 506, and the limit plate 506 can be moved backward by pulling the handle, so that the sieve plate body 502 is taken out of the screening bin 2, and the sieve plate body 502 with a suitable screening aperture is replaced, and then the sieve plate body 502 can be inserted into the screening bin 2 along the installation slot 505, and one end of the sieve plate body 502 is mounted on the supporting spring 504, and the other end is mounted on the front end supporting plate 501, and is in an inclined state and abuts against the discharge port 3. After the front end of the sieve plate body 502 is located on the front end supporting plate 501, it just matches the height of the discharge port 3. When the waste residue falls on the sieve plate body 502, the supporting spring 504 is squeezed under the action of gravity, and the supporting spring 504 is retracted, so that the waste residue is sieved by the vibrating sieve plate body 502 and falls on the lower sieve plate body 502, and is graded and screened in turn to achieve graded separation operations.

[0032] Specifically, Figure 2 and Figure 5As shown, the waste residue component feeding mechanism 4 includes a rotating rod 402 installed inside the feed bin 1, and both ends of the rotating rod 402 are provided with connecting shafts 403, and the connecting shafts 403 are installed on the inner wall of the feed bin 1 through bearings. The waste residue component feeding mechanism 4 also includes a baffle 401 fixed around the rotating rod 402, and the baffle 401 is a cross-shaped structure. The size of the baffle 401 is adapted to the size of the connection between the feed bin 1 and the screening bin 2. The baffle 401 located below the rotating rod 402 is A telescopic rod 405 is installed on one side, and a guide sleeve 406 is sleeved on the outside of the telescopic rod 405. A sliding plate 408 is fixedly connected to one end of the telescopic rod 405 close to the guide sleeve 406, and a return spring 407 is provided between the sliding plate 408 and the guide sleeve 406. A connector 404 is provided on the unconnected ends of the guide sleeve 406 and the telescopic rod 405, and the guide sleeve 406 and the telescopic rod 405 are pin-connected to the screening bin 2 and the baffle 401 respectively through the connector 404.

[0033] By adopting the above technical solution, after the waste slag enters the feed bin 1, it will be located on both sides of the top baffle 401. When the weight of the waste slag on one side is heavier, the gravity of the waste slag is greater than the elastic force of the reset spring 407, and the rotating rod 402 loses balance. At this time, the rear baffle 401 rotates downward, and the waste slag located on the top of the rear baffle 401 enters the screening bin 2. At this time, the reset spring 407 is stretched to make the sliding plate 408 slide in the guide sleeve 406, and the guide sleeve 406 and the telescopic rod 405 are stretched, and the end portion rotates in the connecting piece 404 under the action of the pin shaft, and the angle is adjusted in coordination with the movement of the baffle 401. At the same time, the rotating rod 402 rotates under the action of the connecting shaft 403. As the waste slag falls, the reset spring 407 can push the bottom baffle 401 to reset after being reset, so that the waste slag enters the screening bin 2 in batches.

[0034] Working principle: after the waste slag enters the feed bin 1, it is separated on both sides of the top baffle 401. When the weight of the waste slag on one side is heavy, the rotating rod 402 loses balance, and the rotating rod 402 rotates under the action of the connecting shaft 403, and the waste slag on both sides of the top baffle 401 enters the screening bin 2. As the waste slag enters, the reset spring 407 can push the bottom baffle 401 to reset after being reset. The waste slag is accumulated between the baffles 401 again and enters the feed bin 1 again. Under the action of gravity, the waste slag falls on the sieve plate body 502 and squeezes the supporting spring 504. The supporting spring 504 is retracted, so that the waste slag is sieved by the vibrating sieve plate body 502 and falls on the lower sieve plate body 502. The waste slag is graded and screened in turn to achieve graded separation operations. When the sieve plate body 502 needs to be disassembled, a handle is set at the rear end of the limit plate 506. Pulling the handle can move the limit plate 506 backwards, and the sieve plate body 502 is taken out of the screening bin 2.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
