The second blanking channel is provided with a crushing unit, and the crushing unit is used for crushing large particles scraped into the second blanking channel.

In the use state of the device, waste materials output from the connecting port of the fixed box body 1 enter the first blanking channel and pass through the sieve plate 3 to be filtered and screened. Wherein small particles and most of the moisture in the waste material can pass through the screen deck 3 and be output from the first blanking channel, thereby forming the desired waste liquid; large particles in the waste material are blocked and accumulated on the surface of the sieve plate 3 by the sieve plate 3, and the large particles are continuously scraped into the second discharging channel through the reciprocating movement of the scraper 29, so that the blocking of the sieve plate 3 caused by the large accumulation of the large particles is avoided. The large particles entering the second discharging channel pass through the crushing unit and are output from the second discharging channel after being crushed, so that the required waste residues are formed.

In one or more embodiments, to ensure that more particles remaining on the screen deck 3 are scraped into the second blanking path, the height of the bottom of the scraper 29 and the top surface of the screen deck 3 is therefore defined such that when the scraper 29 is moved onto the screen deck 3, the bottom of the scraper 29 conforms to the top surface of the screen deck 3. This ensures that the scraper 29 is able to scrape the waste material remaining on the screen 3 into the second discharge path, thereby reducing the waste material build up on the screen 3, ensuring that the screen 3 is not blocked by too much waste material.

It will be appreciated that if the portion of the feed opening 30 adjacent to the screen plate 3 has a stepped configuration, it may be possible to inhibit the passage of particles through the feed opening 30, so that the bottom of the feed opening 30 may be level with the screen plate 3 in order to reduce the obstruction of particles in the process of entering the second blanking passage.

In one or more embodiments, a drying unit may be further disposed in the second discharging channel, and the drying unit is located above the pulverizing unit, where the drying unit and the pulverizing unit are sequentially disposed along the discharging path of the second discharging channel. Through the stoving unit, to entering into the waste residue in the second unloading passageway and drying, reduce the moisture of waste residue, reduce the interference that moisture produced in the waste residue crushing process from this, and then improve crushing unit to the crushing effect of large granule in the waste residue for the waste residue of output is more easily directly carried out the resource utilization.

The drying mechanism of the drying unit can be that the drying equipment is set at a higher temperature, so that the waste residue can dry the moisture in the falling process; or the drying equipment is set at a lower temperature, and a platform is arranged in the drying range of the drying equipment, so that the waste residues temporarily stay on the platform for drying.

It should be noted that the lower and higher temperatures are only relative, and the lower temperature is lower than the higher temperature, and the temperature of the drying apparatus is not particularly limited. Generally, a higher temperature means a temperature at which moisture drying can be achieved in the falling waste residue process, and a lower temperature means a temperature at which moisture drying cannot be achieved in the falling waste residue process, and the waste residue needs to be temporarily stopped at a certain stage for drying.

Based on this, in one or more embodiments, in order to reduce energy consumption of the drying apparatus, a lower temperature is selected to be set for the drying apparatus, where the drying unit includes a drying box 10 and a carrying table 27, and the drying box 10 is a box body with the drying apparatus on an inner wall, which is not described in detail in the prior art; the top of the drying box 10 is provided with a first top opening for receiving large particles scraped into the second discharging channel, and the bottom of the drying box 10 is provided with a first bottom opening; the table surface 28 is arranged on one side of the bearing table 27 close to the inlet end of the second blanking channel, and the bearing table 27 can be switched between the first state and the second state by up-and-down reciprocating movement.

When the carrying table 27 is in the first state, as shown in fig. 3, the carrying table 27 is lifted, the table top 28 is located in the drying box 10, the carrying table 27 is matched with the inner cavity of the drying box 10, the table top 28 and the drying box 10 cooperate to form a drying chamber for placing large particles, and at this time, the periphery of the carrying table 27 can be attached to the inner wall of the drying box 10, so that large particles and water in waste residues are blocked from falling, and drying of the waste residue water is practically realized.

When the carrying floor 27 is in the second state, as shown in fig. 2, the carrying floor 27 is lowered, and part or all of the edge of the table top 28 is located below the bottom opening of the drying box 10, and a throwing gap is formed between the table top 28 and the first bottom opening.

By switching the carrying floor 27 between the first state and the second state, the stay of the waste slag in the drying unit and the subsequent throwing can be realized. Specifically, in the first state, the table surface 28 of the carrying table 27 is inside the drying box 10, and the waste residues can be placed in the drying chamber, thereby increasing the stay time of the waste residues in the drying unit and increasing the drying effect of the waste residues; in the second state, the table top 28 of the carrying table 27 is lowered below the first bottom opening, whereby a desired drop gap is formed between the carrying table 27 and the first bottom opening, from which the waste residue originally in the drying chamber can be output to a subsequent comminution unit after the drying is completed.

The switching manner of the carrying platform 27 between the first state and the second state may be that the carrying platform 27 is directly driven to move up and down by a driving device, or may be that automatic reciprocating switching of the carrying platform 27 between the first state and the second state is realized by an elastic member.

Based on the above-described scheme using the elastic member, in one or more embodiments, the elastic member may be disposed between the drying box 10 and the loading table 27 so that the loading table 27 always has a tendency to be switched from the second state to the first state by the tensile force of the elastic member.

Thus, the automatic reset of the bearing table 27 from the second state to the first state is realized by pulling the bearing table 27 by the elastic member, and a threshold value is provided for the weight of the waste residue which can be borne by the bearing table 27 in the first state: when the scraper 29 scrapes the waste residue so that the weight of the waste residue on the carrying table 27 is greater than the threshold value, the carrying table 27 enters the second state, so that the waste residue is output from the throwing gap until the weight of the waste residue on the carrying table 27 is no longer greater than the threshold value, and the carrying table 27 automatically resets to the first state under the action of the tensile force, so that the waste residue on the carrying table 27 is continuously dried. Thereby automatic reciprocating switching of the carrying platform 27 in the first state and the second state is achieved by cooperation of the elastic member and the scraper 29.

Through the relative slip of spout 34 and slider 32, the direction of movement of restriction plummer 27, and then ensure the cooperation between plummer 27 and the stoving case 10, avoid plummer 27 under the second state, because the deviation of its horizontal position leads to taking place the jam between plummer 27's mesa 28 and the first bottom opening, and then lead to plummer 27 unable to reset to the condition of first state.

To facilitate the slip of the slag off the table 28, the table 28 may be sloped so that, in one or more embodiments, the table 28 has a highest point and the height of the table 28 decreases from the highest point to the edge of the table 28. At this time, the whole table top 28 of the carrying table 27 has a certain gradient, so as to guide the waste material on the table top 28 to naturally slide out of the throwing gap when the carrying table 27 is in the second state, thereby avoiding the waste material from accumulating on the carrying table 27 in the second state, and improving the utilization rate of the waste material.

Furthermore, in combination with the provision of the elastic member, the slope can also serve as an effect of guiding the table top 28 of the carrying floor 27 to slide from the first bottom opening into the drying box 10. By engaging with the slide groove 34 and the slider 32, the carriage 27 can be ensured to be smoothly reset from the second state to the first state.

In addition, through the stoving case 10 to the stoving of waste residue on the plummer 27, can reduce the viscosity of waste residue, reduce the quantity that the waste residue adheres to plummer 27 mesa 28, from this can further avoid the waste material still to pile up on plummer 27, improve the utilization ratio of waste material.
