DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0025] like Figure 1-4 As shown, the utility model provides a quick-detachable centrifugal filtering device, including a base 1, an outer shell 2 is provided on the base 1, a rotating part 4 and a drum 3 are provided in the outer shell 2, the rotating part 4 includes a rotor 41 and a driving motor 42 installed in the base 1, the transmission shaft of the driving motor 42 is connected to the rotor 41, and the rotor 41 is connected to the drum 3; the rotor 41 is truncated, the bottom of the drum 3 is recessed inward to form an extension part 31, and the extension part 31 is adapted to the shape and size of the rotor 41; a plurality of through holes are provided on the side wall of the drum 3 and at the position of the non-extension part 31 of the bottom of the drum 3.

[0026] In one embodiment, the rotor 41 is connected to the drum 3 through a fixing portion 5, and the fixing portion 5 includes a plurality of first cavities 51, a second cavity 53 and a third cavity 59 provided in the rotor 41, one end of each first cavity 51 extends to the side wall of the rotor 41, one end of the second cavity 53 extends to the top of the rotor 41, and the other end of each first cavity 51 and the other end of the second cavity 53 are both connected to the third cavity 59; the fixing portion 5 also includes a first hydraulic rod 52 fixedly connected to each first cavity 51, a second hydraulic rod 54 fixedly connected to the second cavity 53, and a diverter 55 fixedly connected to the third cavity 59, and the second hydraulic rod 54 and each first hydraulic rod 52 are respectively connected to the diverter 55 through a hollow hose 56.

[0027] In one embodiment, a protrusion 57 is fixedly connected to one end of each first hydraulic rod 52 away from the diverter 55 , and a plurality of grooves 58 matching the protrusion 57 are formed on the side wall of the extension portion 31 .

[0028] In one embodiment, a battery and a switch are disposed on the base 1 , and the switch is electrically connected to the battery and the drive motor 42 , respectively.

[0029] Before using the centrifugal filtering device, first place the drum 3 on the rotor 41. Under the action of the weight of the drum 3, the second hydraulic pipe is squeezed downward, and the hydraulic oil inside it passes through the diverter 55 and evenly enters each first hydraulic pipe. At this time, each first hydraulic rod 52 pushes the protrusion 57 fixed thereto to move along the first cavity 51 toward the side wall of the rotor 41 until it is removed from the rotor 41 and inserted into the groove 58 opened on the extension part 31. At this time, the fixing work of the drum 3 is completed. Then, a filter bag is set on the drum 3, and the solid-liquid mixture to be separated is poured into the filter bag. After completing the above steps, turn on the switch, and the driving motor 42 drives the drum 3 to rotate through the transmission shaft, and the liquid in the filter bag is thrown out from several through holes by centrifugal force.

[0030] In one embodiment, the protrusion 57 is in the shape of a right-angled trapezoid, the first hydraulic rod 52 is fixedly connected to the right-angled surface of the protrusion 57 , and the deepest part of the inner space of the groove 58 is matched with the inclined surface of the protrusion 57 .

[0031] It should be noted that, when the rotating drum 3 is not installed, the protrusions 57 are completely received in the corresponding first cavities 51 .

[0032] In one embodiment, one end of the first cavity 51 located on the side wall of the rotor 41 is the opening of the first cavity 51. When the opening of the first cavity 51 intersects with the opening of the groove 58, the protrusion 57 just moves to the opening position. As the drum 3 moves downward, the opening of the first cavity 51 and the groove 58 gradually overlap. At the same time, the protrusion 57 moves into the groove 58 at a uniform speed. When the protrusion 57 completely enters the groove 58, the second hydraulic pipe is recovered to the minimum extension position.

[0033] In one embodiment, the inclined surface of the protrusion 57 faces the opening of the first cavity 51, and the upper base of the protrusion 57 contacts the lower surface of the first cavity 51, and the upper base contacts the upper surface of the first cavity 51. In this way, the protrusion 57 will not get stuck with the side wall of the groove 58 during the process of aligning the opening of the first cavity 51 with the groove 58.

[0034] In one embodiment, each first cavity 51 and each groove 58 are opened to be inclined downward.

[0035] In one embodiment, one end of the second hydraulic rod 54 away from the diverter 55 is fixedly connected to the limit plate 6, and a spring 7 is sleeved on the first hydraulic rod 52, and the two ends of the spring 7 are respectively fixedly connected to the limit plate 6 and the top wall of the rotor 41. When the drum 3 needs to be removed, the drum 3 is slowly lifted upward, and under the action of external force, the drum 3 cancels the pressure applied to the second hydraulic rod 54 due to its own weight, and then under the action of the spring 7, the second hydraulic rod 54 gradually extends. At this time, the hydraulic oil in the first hydraulic rod 52 re-enters the second hydraulic rod 54 through the separator, and the first hydraulic rod 52 drives the protrusion 57 to be recovered until the protrusion 57 is completely removed from the groove 58, and then the drum 3 can be taken out.

[0036] In one embodiment, the second cavity 53 and each first cavity 51 are both in the shape of a rectangle, and the side wall of each protrusion 57 fits with the side wall of the corresponding first cavity 51 .

[0037] In one embodiment, the second hydraulic rod 54 is coaxially arranged with the second cavity 53, and the side wall of the second hydraulic rod 54 is in contact with and fixedly connected to the surrounding side walls of the second cavity 53; each first hydraulic rod 52 is coaxially arranged with the corresponding first cavity 51, and the side wall of each first hydraulic rod 52 is in contact with and fixedly connected to the surrounding side walls of the corresponding first cavity 51.

[0038] In one embodiment, the diameter of the second hydraulic rod 54 is greater than that of the first hydraulic rod 52, and the sum of the internal volumes of all the first hydraulic rods 52 is equal to the volume in the second hydraulic rod 54. This allows the hydraulic oil in the second hydraulic rod 54 to be fully distributed in each first hydraulic rod 52 after the second hydraulic rod 54 is fully pressed down to the minimum extension position.

[0039] In one embodiment, a drain port is provided at the bottom of the outer shell 2, a drain pipe is provided in the base 1, one end of the drain pipe is connected to the drain port, and the other end of the drain pipe passes through the base 1 and extends to the outside. During the solid-liquid separation process, the liquid is thrown out by the drum 3 and discharged through the drain pipe at the bottom of the outer shell 2.

[0040] In one embodiment, a feeding pipe and a washing pipe are provided on the top cover 8, and one end of the feeding pipe and the washing pipe both pass through the top cover 8 and extend into the outer shell 2. During the operation of the equipment, the feeding pipe can be used to feed the inside of the equipment, thereby avoiding the previous working mode in which the drum 3 needs to be stopped, thereby improving the working efficiency of the equipment. The washing pipe can further improve the cleaning efficiency of the residual liquid inside the equipment. The equipment is started, and the liquid for cleaning is then added through the washing pipe. Under the centrifugal effect of the drum 3, the liquid splashes around through the through hole. This method effectively flushes the side wall of the drum 3, the through hole and the inner wall of the outer shell 2, thereby improving the cleaning efficiency of the equipment. The liquid for cleaning flows to the bottom of the outer shell 2 along the inner wall of the outer shell 2 and flows out through the drain pipe.

[0041] In one embodiment, a placement groove is opened in the base 1, one end of the placement groove extends to the upper surface of the base 1, and the other end of the placement groove extends to the side wall of the base 1. The drain outlet is aligned with the end of the placement groove located on the upper surface of the base 1 and extends into the placement groove. The drain pipe is inserted into the placement groove, and one end of the drain pipe is connected to the drain outlet, and the other end extends from the end of the placement groove located on the side wall of the base 1 to the outside.

[0042] In one embodiment, a plurality of limit plates are fixedly connected to the bottom of the side wall of the outer shell 1, and a plurality of toggle clamps corresponding to each limit plate are provided on the upper surface of the base 1. When installing the outer shell 2, the drain port is first aligned with one end of the placement groove on the base 1, and the drain port is inserted into the placement groove, and then the corresponding limit plate is fixed and limited by the toggle clamp. This method reduces the difficulty of disassembly and assembly of the device and improves the maintenance efficiency of the device.

[0043] It should be noted that when the outer shell 2 is placed on the base 1 , the lower surface of the limiting plate fits with the upper surface of the base 1 .

[0044] In one embodiment, a top cover 8 is rotatably connected to the outer shell 2, and a plurality of buckle seats are provided on the top cover 8, and an adjustable lock corresponding to each buckle seat is provided on the outer shell 2. The top cover 8 can effectively prevent liquid from splashing out of the outer shell 2 during the solid-liquid separation process.

[0045] In one embodiment, a plurality of guide wheel 82 brackets 81 are fixedly connected to the bottom of the top cover 8, and the guide wheel 82 brackets 81 are arranged in a circle with the mid-perpendicular line of the top cover 8 as the center, and each guide wheel 82 bracket 81 is respectively sleeved and rotatably connected with a guide wheel 82, and the surface of each guide wheel 82 is in contact with the upper surface of the drum 3. After the top cover 8 is closed, the guide wheel 82 in contact with the upper surface of the drum 3 can limit the drum 3, which ensures the stable operation of the equipment while also reducing the vibration generated by the equipment during operation.

[0046] In one embodiment, the guide wheel 82 is an H-shaped double-sided track wheel. The two sides of the guide wheel 82 can further limit the drum 3, thereby further reducing the vibration of the drum 3 during operation, thereby improving the stability of the equipment.

[0047] It should be noted that the above-mentioned toggle clamp, buckle seat, adjustable lock and guide wheel are all existing technologies that are well known in the prior art, so their specific structure and working process will not be further elaborated in this article.

[0048] In one embodiment, an annular baffle is fixedly connected to the bottom surface of the inner space of the outer shell 2, and the height of the baffle is lower than the length of the transmission shaft in the outer shell 2. The annular baffle effectively prevents the separated liquid from contacting the transmission shaft, and prevents the liquid from flowing out of the gap between the transmission shaft and the outer shell 2, effectively improving the service life and efficiency of the equipment.

[0049] In one embodiment, a pull rod is rotatably connected to one side of the base 1, and a plurality of universal wheels are installed at the bottom of the base 1. The pull rod and the universal wheels cooperate with each other, thereby improving the maneuverability of the device and reducing the inconvenience caused by the staff moving the solid-liquid mixture to the centrifugal filtration device.
