Description

Technical Field

[0001] This utility model relates to the field of vacuum filtration technology, and in particular to a water washing component for a calcium sulfate ultrafine fiber vacuum filtration device. Background Technology

[0002] A vacuum filter press is a device that uses vacuum negative pressure to achieve solid-liquid separation. In the production process of calcium sulfate ultrafine fiber, vacuum filter press is one of the important production equipment. It is used to separate solids and liquids in calcium sulfate ultrafine fiber, so that solid impurities remain on the filter plate and the liquid flows into the volumetric flask.

[0003] Current vacuum filtration equipment requires disassembling and cleaning the filter plates after processing calcium sulfate ultrafine fibers. Localized blockage of the filter plates can affect the filtration effect of subsequent processing. However, disassembling and cleaning the filter plates every once in a while is time-consuming and affects the efficiency of calcium sulfate ultrafine fiber processing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a water washing component for a calcium sulfate ultrafine fiber vacuum filtration device that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water washing component for a calcium sulfate ultrafine fiber vacuum filtration device includes: a fixed pipe, a filter bucket, and a filter plate. The filter bucket is disposed on the fixed pipe, and the filter plate is disposed inside the filter bucket. The device further includes: a rubber cone fixedly disposed inside the fixed pipe; a discharge pipe disposed on the lower side of the rubber cone, and a second solenoid valve disposed inside the discharge pipe; a water pump; a cleaning pipe disposed between the drain end of the water pump and the fixed pipe, with one end of the cleaning pipe near the fixed pipe positioned between the rubber cone and the filter plate; a third solenoid valve disposed inside the cleaning pipe; a drain pipe disposed on the filter bucket, with one end of the drain pipe near the filter bucket positioned on the upper side of the filter plate; and a first solenoid valve disposed inside the drain pipe.

[0007] Preferably, the lower side of the fixing tube is provided with a connecting thread.

[0008] To further enhance the flushing force, a movable plate is slidably disposed inside the fixed tube, and the movable plate is fixedly connected to the lower end of the rubber cone. An electric telescopic rod is symmetrically fixedly connected between the fixed tube and the movable plate.

[0009] To further simplify cleaning, a fixing plate is fixedly connected inside the fixing pipe, the lower end of the electric telescopic rod is fixedly connected to the fixing plate, and the liquid outlet pipe is slidably connected to the fixing plate in a sealed manner.

[0010] To prevent liquid from entering the cleaning tube during vacuum filtration, the cleaning tube is further inclined at one end near the fixed tube, and an inclined plate matching the cleaning tube is fixedly connected inside the fixed tube.

[0011] To facilitate the removal of stubborn impurities from the filter plate, a rotating shaft is rotatably provided on the filter plate. Multiple fan blades are fixedly connected to one end of the rotating shaft near the fixed tube, and a scraper matching the filter plate is fixedly connected to the upper end of the rotating shaft.

[0012] Compared with the prior art, this utility model provides a water washing component for a calcium sulfate ultrafine fiber vacuum filtration device, which has the following beneficial effects:

[0013] 1. This calcium sulfate ultrafine fiber vacuum filtration equipment uses a water washing component. After the calcium sulfate ultrafine fiber is filtered by the vacuum filtration equipment, the second solenoid valve in the outlet pipe is closed first. Then, clean water is drawn by a water pump and transported to the space between the rubber cone and the filter plate through the cleaning pipe. At this time, the filter plate is rinsed by backwashing. The cleaned water is discharged through the drain pipe, so there is no need to remove the filter plate for cleaning separately. The use of a built-in water washing component can effectively improve the cleaning efficiency and the processing efficiency of calcium sulfate ultrafine fiber.

[0014] 2. The calcium sulfate ultrafine fiber vacuum filtration equipment uses a water washing component. By controlling two electric telescopic rods to reciprocate, the electric telescopic rods drive the lower end of the rubber cone to move up and down repeatedly through the moving plate, thereby quickly flushing the water between the rubber cone and the filter plate out of the filter plate, thus effectively improving the cleaning effect.

[0015] 3. The calcium sulfate ultrafine fiber vacuum filtration equipment uses a water washing component. The water flow impacts the fan blades, which drives the rotating shaft to rotate. The rotating shaft then scrapes the impurities on the scraper, thereby effectively improving the cleaning effect.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model can effectively improve its cleaning efficiency and the efficiency of processing calcium sulfate microfiber by using a built-in water washing component.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figures 1-3 A water washing component for a calcium sulfate ultrafine fiber vacuum filtration device includes: a fixed pipe 1, a filter bucket 101, and a filter plate 102. The filter bucket 101 is disposed on the fixed pipe 1, and the filter plate 102 is disposed inside the filter bucket 101. The device also includes: a rubber cone 2, fixedly disposed inside the fixed pipe 1; a liquid outlet pipe 201 disposed on the lower side of the rubber cone 2, and a second solenoid valve 202 disposed inside the liquid outlet pipe 201; a water pump 3; a cleaning pipe 301 disposed between the drain end of the water pump 3 and the fixed pipe 1, with one end of the cleaning pipe 301 near the fixed pipe 1 disposed between the rubber cone 2 and the filter plate 102; a third solenoid valve 302 disposed inside the cleaning pipe 301; a drain pipe 104 disposed on the filter bucket 101, with one end of the drain pipe 104 near the filter bucket 101 disposed on the upper side of the filter plate 102; and a first solenoid valve 105 disposed inside the drain pipe 104.

[0023] A connecting thread 103 is provided on the lower side of the fixed tube 1.

[0024] After the calcium sulfate ultrafine fiber is filtered by the vacuum filtration equipment, the second solenoid valve 202 in the outlet pipe 201 is closed first. Then, clean water is drawn by the water pump 3 and transported to the space between the rubber cone 2 and the filter plate 102 through the cleaning pipe 301. At this time, the filter plate 102 is rinsed by backwashing. The cleaned water is discharged through the drain pipe 104, so it is not necessary to remove the filter plate 102 for cleaning separately. The built-in water washing component can effectively improve its cleaning efficiency and the efficiency of calcium sulfate ultrafine fiber processing.

[0025] In specific implementation, a sludge pump can be connected to the drain pipe 104 to perform auxiliary sludge pumping operations.

[0026] Example 2: Refer to Figures 1-3 A water washing component for a calcium sulfate ultrafine fiber vacuum filtration device is basically the same as that in Example 1. Further, a movable plate 203 is slidably arranged inside the fixed tube 1, and the movable plate 203 is fixedly connected to the lower end of the rubber cone 2. An electric telescopic rod 204 is symmetrically fixedly connected between the fixed tube 1 and the movable plate 203.

[0027] A fixing plate 205 is fixedly connected inside the fixing pipe 1. The lower end of the electric telescopic rod 204 is fixedly connected to the fixing plate 205. The liquid outlet pipe 201 is slidably connected to the fixing plate 205 in a sealed manner.

[0028] When rinsing the filter plate 102, the two electric telescopic rods 204 can be controlled to reciprocate. The electric telescopic rods 204 drive the lower end of the rubber cone 2 to move up and down reciprocally through the moving plate 203, so that the water between the rubber cone 2 and the filter plate 102 can be quickly flushed out of the filter plate 102, thereby effectively improving its cleaning effect.

[0029] By using a sealed sliding connection between the fixed plate 205 and the liquid outlet pipe 201, the filtered liquid can be placed in contact with the electric telescopic rod 204 and the lower side of the rubber cone 2, thereby effectively reducing the difficulty of cleaning.

[0030] The cleaning tube 301 is inclined at one end near the fixed tube 1, and an inclined plate 303 matching the cleaning tube 301 is fixedly connected inside the fixed tube 1.

[0031] A rotating shaft 4 is rotatably mounted on the filter plate 102. Multiple fan blades 401 are fixedly connected to one end of the rotating shaft 4 near the fixed tube 1. A scraper 402 matching the filter plate 102 is fixedly connected to the upper end of the rotating shaft 4.

[0032] As the water flows upward, the water impacts the fan blades 401, causing the rotating shaft 4 to rotate. The rotating shaft 4 then scrapes away the impurities on the scraper 402, thereby effectively improving the cleaning effect.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
