Description
Technical Field
[0001] This utility model relates to the field of water-reducing agent mother liquor filtration, specifically a water-reducing agent mother liquor filtration device. Background Technology
[0002] Water-reducing agents are concrete admixtures that reduce the amount of water used in mixing while maintaining the slump of the concrete. Most of them are anionic surfactants, such as lignin sulfonates, naphthalene sulfonates, and formaldehyde polymers. After being added to the concrete mixture, they have a dispersing effect on cement particles, which can improve its workability, reduce the unit water consumption, improve the fluidity of the concrete mixture, or reduce the unit cement consumption and save cement.
[0003] In the prior art, during the preparation of water-reducing agents, unreacted raw materials and sugar decomposition products, such as methyl allyl polyoxyethylene ether, acrylic acid, sodium gluconate, and white sugar, will produce some particulate or lumpy impurities. It is necessary to filter the water-reducing agent mother liquor to separate it from the water-reducing agent liquid. Existing filtration methods generally use filter screens or filter cloths for filtration. During the filtration process, some solid impurities will accumulate in the pores of the filter screen, causing the filter screen to become clogged and reducing the filtration efficiency. Based on this, this utility model proposes a water-reducing agent mother liquor filtration device. Utility Model Content

[0009] As a further improvement of this utility model: the guiding unit includes a guide plate and a discharge port;
[0010] The guide plate is fixed to the bottom of the filter screen and is symmetrically distributed in an inverted V-shape. The guide plate is used to provide flow guidance for the filtered water-reducing agent. A discharge port for large solid particles is opened on one side of the outer wall of the guide plate.
[0011] As a further embodiment of this utility model: the transmission unit includes a drive motor, a first turntable, a transmission rod, and a second turntable;
[0012] The drive motor is fixed to the outer wall of the filter box by a mounting bracket. The output end of the drive motor is connected to a first turntable through a rotating shaft and a coupling. The eccentric position of the first turntable is rotatably connected to one end of a transmission rod. The other end of the transmission rod is rotatably connected to the eccentric position of a second turntable. The circumferentially rotating first turntable is used to drive the transmission rod to swing the second turntable. The second turntable is fixed to the end of the rotating shaft of the filter plate.
[0013] As a further improvement of this utility model: the guide plate is fixed in the inner cavity of the filter box in the form of two semi-circular structures, and the bottom of the guide plate is provided with a discharge trough for the liquid water-reducing agent to be discharged after filtration.
[0014] As a further embodiment of this utility model: the outer wall diameter of the first turntable is one-third of the outer wall diameter of the second turntable, and the lowest end of the first turntable is flush with the lowest end of the second turntable.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] By setting up a transmission mechanism, when filtering the water-reducing agent mother liquor, the mother liquor is poured into the filter box, allowing it to contact the filter screen. The drive motor is then started to rotate the first turntable circumferentially.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-3 In this embodiment of the present invention, a water-reducing agent mother liquor filtration device includes a filter box 1, a guide plate 2 arranged in an annular pattern is fixed in the inner cavity of the filter box 1, a filter screen plate 3 for filtering the water-reducing agent mother liquor is rotatably connected to the inner cavity of the filter box 1 located in the inner cavity of the guide plate 2, and a transmission mechanism 4 is provided on the filter box 1 to provide power for the swing of the filter screen plate 3.
[0023] Transmission mechanism 4 includes a guide unit and a transmission unit;
[0024] The guiding unit is used to guide the flow of the water-reducing agent mother liquor during the filtration process;
[0025] The transmission unit is used to provide power for the oscillation of the filter plate 3;
[0026] The guiding unit includes a guide plate 401 and a discharge port 402;
[0027] The guide plate 401 is fixed to the bottom of the filter screen plate 3 and is symmetrically distributed in an inverted V-shape. The guide plate 401 is used to provide flow guidance for the filtered water-reducing agent. A discharge port 402 for large solid particles to flow out is opened on one side of the outer wall of the guide plate 2.
[0028] The transmission unit includes a drive motor 403, a first turntable 404, a transmission rod 405, and a second turntable 406;
[0029] The drive motor 403 is fixed to the outer wall of the filter box 1 by a mounting bracket. The output end of the drive motor 403 is connected to the first turntable 404 through a rotating shaft and a coupling. The eccentric position of the first turntable 404 is rotatably connected to one end of the transmission rod 405. The other end of the transmission rod 405 is rotatably connected to the eccentric position of the second turntable 406. The circumferentially rotating first turntable 404 is used to drive the transmission rod 405 to drive the second turntable 406 to swing. The second turntable 406 is fixed to the end of the rotating shaft of the filter screen plate 3.
[0030] In this embodiment: by pouring the water-reducing agent mother liquor to be filtered into the inner cavity of the filter box 1, the water-reducing agent mother liquor will fall into the guide plate 2 and contact the upper surface of the filter screen plate 3. By starting the drive motor 403, the drive motor 403 will drive the first turntable 404 to rotate, causing one end of the transmission rod 405, which is eccentrically connected to the outer wall of the first turntable 404, to rotate circumferentially. The other end of the transmission rod 405 will synchronously push the second turntable 406 to rotate. When the transmission rod 405 connected to one end of the first turntable 404 moves to its maximum distance, the second turntable 406 rotates thirty-five degrees. At this time, the rotation of the first turntable 404 will pull the transmission rod 405 to reset, and the second turntable 406 will swing in the opposite direction again. This reciprocating motion achieves the purpose of swinging the filter screen plate 3, so that the water-reducing agent mother liquor on the upper surface of the filter screen plate 3 can be filtered more efficiently by the filter screen plate 3. When the filter screen plate 3 rotates to the maximum angle, some larger solid impurity particles will be discharged through the discharge port 402 under the inclined filter screen plate 3. The filter screen plate 3 is a porous metal frame with a layer of filter cotton yarn on its surface. The liquid in the water-reducing agent is filtered out through the filter cotton yarn layer, while the solids remain.
[0031] Please refer to this carefully. Figures 1-3 The guide plate 2 is fixed in the inner cavity of the filter box 1 in two semi-circular structures. The bottom of the guide plate 2 is provided with a discharge trough for the liquid water-reducing agent to be discharged after filtration. The outer diameter of the first turntable 404 is one-third of the outer diameter of the second turntable 406. The lowest end of the first turntable 404 is flush with the lowest end of the second turntable 406.
[0032] In this embodiment: This structure allows the filter plate 3 to swing back and forth along the inner cavity of the guide plate 2. Under the action of the small first turntable 404, the first turntable 404 rotates one revolution, and the angle of the second turntable 406 is insufficient to drive the second turntable 406 to flip.
[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.
