Technical Field

[0001] The present invention relates to the field of environmental protection technologies, and particularly to a compound garbage filtering device. Background Art

[0002] In life or industrial production, there are usually fluid-like garbage. During the treatment of this type of garbage, it is usually necessary to remove moisture. The existing methods for removing moisture are usually draining or forcing solid-liquid separation through compression. These treatment methods have low efficiency and take a long time to remove moisture. Especially in summer, the garbage is prone to corruption and deterioration, which also has a greater impact on the surrounding environment. Summary of the Invention

[0003] In view of this, the present invention provides a compound garbage filtering device, which has high efficiency and convenient operation through the filtering device.

[0004] The compound garbage filtering device of the present invention includes a filter cylinder that can be driven to rotate, an outer cylinder sleeved outside the filter cylinder, a cleaning hammer installed inside the filter cylinder, and a bottom cover installed at the bottom of the filter cylinder. The side wall of the filter cylinder is provided with first-stage filtering holes. There is an annular flow channel between the filter cylinder and the outer cylinder. The cleaning hammer fits against the inner wall of the filter cylinder and has a rotational speed difference from the filter cylinder. The bottom cover is composed of several blades symmetrically distributed along the central axis of the filter cylinder. The middle parts of the blades are rotatably fitted on the outer cylinder. When the filter cylinder rotates, the blades are radially inwardly rotated by centrifugal force and are spliced and closed to form a spherical structure and hermetically fit against the bottom of the filter cylinder. When the filter cylinder stops rotating, the blades are radially outwardly rotated by their own weight to open the bottom of the filter cylinder. When the bottom cover seals the bottom of the filter cylinder, the part of the blades located outside the filter cylinder is provided with second-stage filtering holes, and the aperture of the second-stage filtering holes is smaller than that of the first-stage filtering holes.

[0005] Furthermore, it further includes a rotating shaft. The rotating shaft extends into the interior of the filter cylinder from the upper opening end of the filter cylinder and is in driving cooperation with the filter cylinder. A rotating sleeve is rotatably fitted on the rotating shaft. The cleaning hammer is fixedly connected to the rotating sleeve. A resistance device is installed inside the rotating sleeve, and the resistance device is used to provide resistance to prevent the rotating sleeve from rotating.

[0006] Furthermore, the resistance device includes several pairs of magnetic blocks embedded in the inner circle of the rotating sleeve. Each pair of magnetic blocks is located on both sides of the rotating shaft in the radial direction, and the same-sex magnetic poles are radially opposite.

[0007] Furthermore, the cleaning hammer has a tile-shaped structure. The outer circle of the cleaning hammer fits against the inner wall of the filter cylinder. The two circumferential sides of the cleaning hammer have cutting edges for removing the adhesions on the inner wall of the filter cylinder.

[0008] Furthermore, the outer circle at the bottom of the filter cylinder has a rounded corner, and the inner side of the blade has a sealing groove adapted to the bottom of the filter cylinder.

[0009] Furthermore, the inner cavity of the filter cylinder near the lower opening is a tapered cavity that expands downward.

[0010] Furthermore, a counterweight is provided on the outer side of the top of the blade.

[0011] Furthermore, the filter cartridge has an annular baffle extending radially inward at the opening, the upper end of the cleaning hammer is against the bottom of the baffle, the rotating shaft has a support platform extending radially outward below, and the bottom of the rotating sleeve is supported on the support platform.

[0012] Furthermore, the upper end of the blade is bent radially inward, and the counterweight block is connected to the outer side of the bent portion of the blade.

[0013] Beneficial effects of the present invention:

[0014] In the present invention, the rotation of the filter cartridge forces the solid-liquid separation in the garbage through centrifugal force. The liquid filtered out once flows into the secondary filter chamber after passing through the annular flow channel between the filter cartridge and the outer cylinder and is forced to undergo secondary filtration. The secondary filter chamber serves as an auxiliary filtration structure, which not only improves the filtration efficiency but also improves the filtration effect. Moreover, during the rotation of the filter cartridge, the bottom cover automatically closes and seals at the bottom of the filter cartridge to cooperate with the garbage filtration. When the filter cartridge stops, the bottom cover automatically opens and unloads due to the downward pressure of the blades on the blades by the garbage in the filter cartridge and the torque of the blades themselves. The entire control of the filtration device is simple and easy to operate. The cleaning hammer and the filter cartridge have a speed difference, so that the cleaning hammer can slide relative to the inner wall of the filter cartridge to clean the attachments on the inner wall of the filter cartridge, which can prevent the filter holes of the filter cartridge from being blocked and help improve the filtration effect.

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] As shown in the figure, this embodiment provides a compound garbage filtering device, including a filter cartridge 1 that can be driven to rotate, an outer cylinder 2 that is sleeved outside the filter cartridge, a cleaning hammer 3 installed in the filter cartridge, and a bottom cover 4 installed at the bottom of the filter cartridge. A primary filter hole is opened on the side wall of the filter cartridge, and an annular flow channel is provided between the filter cartridge and the outer cylinder. The cleaning hammer is attached to the inner wall of the filter cartridge and has a rotation speed difference with the filter cartridge. The bottom cover is composed of a plurality of blades 4a that are symmetrically distributed along the central axis of the filter cartridge. The middle part of the blade is rotatably mounted on the outer cylinder. When the filter cartridge rotates, the blades rotate radially inward under the centrifugal force, spliced ​​together and closed to form a spherical structure and sealed to the bottom of the filter cartridge. When the filter cartridge stops rotating, the blades rotate radially outward under the action of their own weight to open the bottom of the filter cartridge. When the bottom cover is sealed to the bottom of the filter cartridge, the portion of the blade located outside the filter cartridge is provided with a secondary filter hole, and the aperture of the secondary filter hole is smaller than the aperture of the filter hole. The radial inward rotation and radial outward rotation here refer to the rotation direction of the bottom of the blade. Figure 1 and Figure 2 As shown, the inner diameter of the outer cylinder is larger than the outer diameter of the filter cartridge, the outer cylinder and the filter cartridge are arranged coaxially, and the outer wall of the outer cylinder is connected to the inner wall of the filter cartridge by a fixing rod; the bottom cover is composed of four blades, and the radial inner side of the blade is a quarter of a hemispherical structure. Of course, the number of blades can be adjusted, and a counterweight ear 4b with a trapezoidal structure is connected to the outer side of the blade, and there is a triangular gap between adjacent counterweight ears. The position 15 where the blade and the outer cylinder are hinged is located on the circumference of the inner circle of the counterweight ear, so that when the blade is radially rotated outward to open, the radial outer parts of each blade will not interfere with each other, wherein a plurality of hinged rods 14 corresponding to each blade one by one and extending radially obliquely downward are fixedly connected to the outer wall of the outer cylinder, wherein the inner side of the blade is hinged to the cross The outer end of the connecting rod; by properly adjusting the center of gravity and mass distribution of the blades, when the filter cartridge is stationary, the torque generated by the deadweight of the bottom part of the blade is greater than the torque generated by the deadweight of the top part of the blade, so that each blade rotates radially outward. At this time, the bottom cover is in an open state. When the filter cartridge is rotating, due to the large rotation radius of the top part of the blade, the rotation torque generated at the top of the blade is greater than the rotation torque at the bottom of the blade. At this time, each blade rotates radially inward and closes and is sealed at the bottom of the filter cartridge; the cleaning hammer and the filter cartridge have a speed difference, so that the cleaning hammer can slide relatively on the inner wall of the filter cartridge to clean the attachments on the inner wall of the filter cartridge, which can prevent the filter holes of the filter cartridge from being blocked, which is conducive to improving the filtering effect; combined with Figure 2 As shown in FIG. 1 , after the blades are closed, the portion of the blades located outside the filter cartridge and the outer wall of the filter cartridge form a secondary filter cavity 10. The liquid filtered by the filter cartridge flows into the secondary filter cavity through the annular cavity and is forced to pass through the secondary filter holes as the blades rotate to achieve filtration. The secondary filter cavity only serves as an auxiliary filtration structure. To ensure the good filtration function of the secondary filter cavity, the bottom of the outer cylinder can be Figure 1The filter cartridge is a filter element that is used to filter the garbage from the filter cartridge and filter element to a filter element, and the filter cartridge has a plurality of filter elements that are used to filter the garbage. The filter cartridge has a plurality of filter elements that are used to filter the garbage from the filter cartridge and filter element to a filter element ...

[0020] In this embodiment, a rotating shaft 5 is also included. The rotating shaft extends from the opening end of the filter cartridge into the interior of the filter cartridge and cooperates with the filter cartridge in transmission. A rotating sleeve 6 is rotatably sleeved on the rotating shaft. The cleaning hammer is fixedly connected to the rotating sleeve. A resistance device is installed in the rotating sleeve. The resistance device is used to provide resistance to prevent the rotating sleeve from rotating. Figure 1 As shown, an external motor can be connected to the rotating shaft. In addition, the rotating shaft is connected to the inner wall of the open end of the filter cartridge through a radial transmission rod 11. The cleaning hammer is connected to the outer wall of the rotating sleeve through a connecting rod. When the rotating shaft rotates, the filter cartridge can be driven to rotate. At the same time, the rotating sleeve can rotate freely, which is beneficial to maintaining the speed difference between the rotating sleeve and the rotating shaft. The rotating sleeve has a resistance to prevent its rotation, which can increase the corresponding circumferential supporting force for the cleaning hammer, which is beneficial for the cleaning hammer to clean the attachments on the inner wall of the filter cartridge.

[0021] In this embodiment, the resistance device includes a plurality of pairs of magnetic blocks 9 embedded in the inner circle of the rotating sleeve, each pair of magnetic blocks is located on both sides of the rotating shaft in the radial direction and the same magnetic poles are radially opposite. Figure 1 As shown, the inner circle of the rotating sleeve is provided with two pairs of magnets arranged axially, and the like poles of each pair of magnets are arranged radially opposite to each other. Of course, the number of pairs of magnets can be adjusted accordingly according to actual conditions, and the details are not repeated here. In order to adapt to the magnetic force of the magnets, the rotating sleeve can be set as a hollow shaft, and each pair of magnets enables the rotating sleeve to generate a damping force during the rotation process, which can not only maintain the speed difference between the rotating sleeve and the rotating shaft, but also increase the circumferential support force for the cleaning hammer.

[0022] In this embodiment, the cleaning hammer is in a tile-like structure, the outer circle of the cleaning hammer is in contact with the inner wall of the filter cartridge, and the two circumferential sides of the cleaning hammer have cutting edges for removing adherents on the inner wall of the filter cartridge. Figure 3 As shown, when the cleaning hammer rotates relative to the inner wall of the filter cartridge, the attached matter can be removed through the cutting edge.

[0023] In this embodiment, the outer circumference of the bottom of the filter cartridge has a rounded corner, and the inner side of the blade has a sealing groove 7 adapted to the bottom of the filter cartridge. When each blade rotates and closes, the sealing groove on the blade cooperates with the bottom of the filter cartridge to achieve sealing. A sealing strip can be installed in the sealing groove to improve the sealing performance between the bottom of the filter cartridge and the blade. In addition, sealing strips are also installed at the edges of the blades accordingly, so as to improve the sealing performance at the joints of adjacent blades.

[0024] In this embodiment, the inner cavity of the filter cartridge near the lower opening is a tapered cavity that expands downward. Figure 1 As shown, there is a certain distance between the bottom of the cleaning hammer and the bottom of the filter cartridge, so that the solid waste in the tapered cavity at the bottom of the filter cartridge is not interfered by the cleaning hammer. The setting of the tapered cavity enables the waste in the filter cartridge to deposit downward along the inner wall of the tapered cavity, which is convenient for the extrusion molding of the waste. In addition, by setting a reasonable tapered angle, the downward pressure of the waste on the bottom cover can be controlled.

[0025] In this embodiment, a counterweight 8 is arranged on the outer side of the top of the blade. By arranging the counterweight, it is beneficial to flexibly adjust the mass distribution of the blade, so that when the blade is stationary, the bottom rotates radially outward to open, and when rotating, the bottom of the blade rotates radially inward to close.

[0026] In this embodiment, the upper opening of the filter cartridge has an annular baffle 12 extending radially inward. The upper end of the cleaning hammer abuts against the lower side of the baffle. There is a support platform 13 extending radially outward below the rotating shaft, and the bottom of the rotating sleeve is supported on the support platform. The annular baffle and the support platform are beneficial to axially position the cleaning hammer. In addition, the annular baffle is beneficial to prevent the waste from splashing upward. Self-lubricating bearings can be arranged between the annular baffle and the top of the cleaning hammer, and between the support platform and the bottom of the cleaning hammer to reduce the frictional resistance of the cleaning hammer.

[0027] In this embodiment, the upper end of the blade bends radially inward, and the counterweight is connected to the outer side of the bent part of the blade. Figure 2 As shown, the bent part is beneficial to the installation of the counterweight. When the bottom of the blade rotates outward, the bent part of the blade rotates inward and abuts against the outer circumference of the outer cylinder to control the maximum opening angle of the blade. The opening angle of the blade can be flexibly controlled by the bending angle of the bent part.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
