DETAILED DESCRIPTION

[0022] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model are described in detail as follows in combination with the drawings and preferred embodiments.

[0023] Referring to Figures 1 to 5 The utility model discloses a circulating residue discharging anti-blocking evaporator, which comprises a discharge port 6, the discharge port 6 is provided with a filter, the filter comprises a circular filter screen 7, the filter screen 7 is provided with a residue discharge port 8, and the utility model further comprises a cleaning portion 11, which discharges the filtered sundries from the residue discharge port 8. Figure 1 Referring to Figure 2 The filter is mainly arranged on the discharge port 6, and can also be arranged at other required positions. Figure 3 and Figure 4As shown, the filter includes a filter screen 7, which is circular, and is provided with a fan-shaped slag discharge port 8, which is connected to a chute 9 with a plurality of holes in the bottom, and the chute 9 can be provided with side stops on both sides. The chute 9 is connected to the hole provided in the side wall of the discharge pipe 14, which is in communication with the storage tank 10. The storage tank 10 is sealed from the outside and is provided with an openable cover. The cleaning part 11 includes a base, and an elastic cleaning block connected below the base. The cleaning block is in contact with the surface of the filter screen 7, and is shaped as a rectangular block, which is arranged in the radial direction and extends from the center to the outer circumference of the filter screen 7. The surface of the filter screen 7 is scraped and cleaned, and the slag and other impurities are pushed into the slag discharge port 8 and then into the storage tank 10 along the chute. The upper end of the evaporator is generally provided with a foam removal device, which usually includes a motor and a rotating plate driven by the motor for scraping or removing foam. In this embodiment, the rotating plate or connecting rod body can be extended to the base and connected or cooperated with the base. When the defoaming operation is performed, the base of the cleaning part 11 is moved to clean the filter screen 7. When it moves to the slag discharge port 8, the impurities fall into the slag discharge port 8 and then into the chute and finally into the storage tank 10. This structure not only avoids the need to set up a driving structure, but also can stir the liquid by the rotating plate to improve the evaporation efficiency.

[0024] In the above embodiments, with reference to Figure 3 As shown, the filter screen 7 includes a plurality of concentric rings 701 connected together, and each concentric ring 701 includes an initial portion 702 and a rear portion 703. A part or all of the rear portions of the concentric rings 701 extend downward of the filter screen 7 and form the chute 9. The rear portion 703 of the concentric ring 701 extending downward is spaced apart from the initial portion 702 by a predetermined distance to form the slag discharge port 8. The lower part of the cleaning block can be provided with a plurality of grooves matched with the concentric rings 701. The spacing between adjacent concentric rings 701 is generally the same, and the spacing is determined according to the size of the impurities in the concentrated material. The lower part of the cleaning block extends to the surface of the steel wire. Figure 3 and Figure 4 A guide rail 12 concentric with the concentric rings 701 can also be provided, and the cleaning part 11 is connected to the guide rail 12 and moves along the guide rail 12. Preferably, the rear portion 703 and the initial portion 702 of some of the concentric rings 701 are connected, and the concentric rings 701 connected by the rear portion 703 and the initial portion 702 are spaced apart from the concentric rings 701 whose rear portions 703 extend downward. This structure mainly prevents the elastic cleaning block from being stuck after one round around the filter screen 7 by using the guiding effect of the concentric rings 701. In addition, the initial portion can also be arc-shaped and extend downward by a small section to reduce resistance.

[0025] In the above embodiment, referring to Fig. 5, the main body of the filter screen 7 is formed in an inverted "concave" shape or an arc shape, a groove 704 is arranged at the outer side of the bottom of the main body of the filter screen 7, and the cleaning part 11 and the slag discharge port are arranged in the groove 704. This structure makes the impurities filtered out enter the groove 704 under the action of gravity and be pushed to the slag discharge port by the cleaning part arranged in the groove 704. The groove 704 can also be arranged in a spiral shape and connected with a slide, and the impurities can enter the slag discharge port 8 under the action of gravity by using the inclined angle, so that it is not necessary to arrange a motor and a cleaning block to clean the groove 704. The groove can also be replaced by a spiral-shaped whole filter screen, which can also achieve similar effects.

[0026] In the above embodiment, the cleaning part 11 and the spiral-shaped surface arranged therein delay the time of clogging of the filter screen 7 to a certain extent, thereby reducing the frequency of cleaning of the evaporator, and the other side of the filter screen 7 is still scaled and causes the passage available for the liquid to become smaller, so that the evaporator still needs to be cleaned at intervals and the filter screen 7 needs to be replaced or cleaned, and the impurities in the storage tank 10 are removed.

[0027] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with reference to the preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make slight changes or modifications to the above disclosed technical content to obtain equivalent embodiments without departing from the technical solution of the present application. Any modification, equivalent change and modification of the above embodiment made according to the technical essence of the present application still belongs to the scope of the technical solution of the present application.
