Description

Technical Field

[0001] The utility model relates to the technical field of vacuum filtration, in particular to a vacuum filtration device. Background Art

[0002] The vacuum filter forms negative pressure at the filtrate outlet as the driving force for filtration. This type of filter is divided into two types: intermittent operation and continuous operation. The intermittent operation vacuum filter can filter suspensions of various concentrations, and the continuous operation vacuum filter is suitable for filtering thick suspensions containing more solid particles.

[0003] For example, a vacuum filtration device with announcement number CN210251415U solves the problems of low filtration efficiency and inconvenient cleaning of existing vacuum filtration devices. The vacuum filtration device includes a funnel, a filter and a filtration bottle arranged in sequence from top to bottom, the lower end of the funnel is detachably connected to the upper end of the filter, a filter cloth is detachably provided in the filter, and the lower end of the filter is detachably connected to the upper end of the filtration bottle.

[0004] When the above device is in use and is filtering solids and liquids, when the solid particles on the filter cloth inside the device accumulate on the surface, the filtration speed will be affected, causing the entire filtration rate to slow down. If the filter is opened for cleaning, the material inside the filtration bottle will be contaminated, causing the raw materials inside the entire filtration bottle to be wasted, and the entire filtration process cannot proceed smoothly.

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.

[0026] Example 1

[0027] See also Figures 1 to 6 , which is the first embodiment of the utility model, provides a technical solution: a vacuum filtration device, including a filtration bottle 1, the filtration bottle 1 is used to place a filtering component 4 and store the liquid after the filtration is completed, the filtration bottle 1 is provided with an opening and closing clamp 2, the opening and closing clamp 2 is used to move a feed bottle 3, so that the feed bottle 3 can be closely fitted with the filtration bottle 1, and the opening and closing clamp 2 is provided with a feed bottle 3, and a filtering component 4 is provided inside the filtration bottle 1, and the filtering component 4 is used to filter the mixed liquid;

[0028] The filter assembly 4 includes an annular frame 41 movably arranged on the suction filter bottle 1, the annular frame 41 is used for support, a sliding cavity 42 arranged in an array on the annular frame 41, the sliding cavity 42 is used to cooperate with a sliding rod 43, a sliding rod 43 movably arranged on the sliding cavity 42, a fan-shaped plate 44 arranged on the sliding rod 43, the fan-shaped plate 44 is used to drive the fan-shaped plate 44 to be synchronously lifted up by a filter clamping plate 45 when the first filter paper 46 is lifted up in a conical shape, a filter clamping plate 45 arranged on the fan-shaped plate 44, the filter clamping plate 45 is used to clamp the first filter paper 46, and the first filter paper 46 is tightly clamped on the surface of the fan-shaped plate 44, the first filter paper 46 is arranged on the side of the fan-shaped plate 44 away from the annular frame 41, and the first filter paper 46 is clamped between the filter clamping plate 45, the first filter paper 46 is used to filter the liquid inside the feed bottle 3, and also includes a bag net 47 arranged in an array on the annular frame 41, the bag net 47 is used to collect solid particles on the surface of the first filter paper 46.

[0029] An array of snap-fit ​​plates 411 are arranged on the annular frame 41, and the snap-fit ​​plates 411 are used to snap-fit ​​with the matching plates 471 on the bag net 47, so that the bag net 47 is snapped on the annular frame 41. Matching plates 471 are symmetrically arranged on the outside of the bag net 47, and the matching plates 471 and the snap-fit ​​plates 411 are snap-fitted and connected. A through groove 472 is opened on the bag net 47, and the through groove 472 and the sliding cavity 42 do not contact each other. The through groove 472 is used to prevent the sliding cavity 42 from causing squeezing damage to the bag net 47.

[0030] A through port 5 is provided inside the suction filtration bottle 1 for collecting the filtered liquid. A second filter paper 48 is provided on the through port 5, and the second filter paper 48 and the net 47 do not contact each other.

[0031] During use, first lock the suction bottle 1 and the feed bottle 3 together through the opening and closing clamp 2, then pour the mixed liquid to be filtered into the feed bottle 3, turn on the vacuum pump 8 to form a negative pressure inside the suction bottle 1, so that the mixed liquid can be filtered more quickly, and when the mixed liquid passes through the first filter paper 46 inside the suction bottle 1, the solid particles will be intercepted on the surface of the first filter paper 46. When there are enough solid particles on the surface of the first filter paper 46 to affect the filtration rate, close the valve 71 and press the air blowing ball 61 to blow air into the suction bottle 1. Under the action of the gas, the first filter paper 46 bulges to form a cone shape, and the bulging of the first filter paper 46 drives the fan plate 44 to be lifted up synchronously. The cooperation between the sliding rod 43 rotatably connected under the fan plate 44 and the sliding cavity 42 will limit the moving direction of the fan plate 44, and at the same time enable the fan plate 44 to shrink inward by a certain distance, so that the solid particles can smoothly enter the net 47 when rolling downward, completing the collection of the solid particles on the surface of the first filter paper 46, and then reopen the valve 71 to carry out a filtration process.

[0032] Example 2

[0033] See also Figures 1 to 6 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0034] A connecting hose 6 is provided on one side of the suction bottle 1, and a blast ball 61 is provided on the side of the connecting hose 6 away from the suction bottle 1. The blast ball 61 is used to blow air into the suction bottle 1 so that the first filter paper 46 can be lifted up to form a cone shape.

[0035] An air inlet pipe 11 is arranged on one side of the suction filter bottle 1, and an air suction hose 7 is arranged on the air inlet pipe 11. The air suction hose 7 and the air inlet pipe 11 are sleeved together to form a closed space.

[0036] A valve 71 is provided on the vacuum hose 7, and a vacuum pump 8 is provided at one end of the vacuum hose 7 away from the air inlet pipe 11. The vacuum pump 8 is used to evacuate the interior of the suction filtration bottle 1 to form a negative pressure space, thereby accelerating the filtering speed of the mixed liquid.

[0037] During use, when it is necessary to process the solid particles on the first filter paper 46, the negative pressure state inside the suction bottle 1 is released by closing the valve 71 installed on the exhaust hose 7 connected to the vacuum pump 8. At the same time, during this process, the staff blows air into the suction bottle 1 by squeezing the air blast ball 61, so that the first filter paper 46 can lift up and transfer the solid particles accumulated on the surface, and the net 47 installed on the annular frame 41 can collect the solid particles. The liquid that falls together during the collection process will be filtered under the action of the second filter paper 48 to avoid the liquid that enters the suction bottle 1 together with the solid particles without being filtered, affecting the quality of the entire filtered liquid. After the entire filtration is completed, the filter assembly 4 can be taken out from the inside of the suction bottle 1, and each component can be disassembled and cleaned, and the filter assembly 4 can be recycled.

[0038] The remaining structures are the same as those of Example 1.
