Description

Technical Field

[0001] The utility model relates to the technical field of concrete water reducing agent production, in particular to a purification device for concrete water reducing agent production. Background Art

[0002] Concrete water reducer is a surfactant whose molecule consists of two parts: a hydrophilic group and a hydrophobic group. Water reducer can significantly improve the performance of concrete, including fluidity, strength, durability, etc. When the water reducer raw materials are used to prepare the water reducer mother liquor through the reactor, the mother liquor needs to be purified. The purification work mainly includes two aspects. On the one hand, the mother liquor is evaporated at high temperature in water to evaporate low-boiling point compounds such as ethers in the mother liquor. On the other hand, impurities in the mother liquor are filtered out, such as inorganic salt crystals such as calcium sulfate, which may be by-products produced during the reaction process or brought in from the raw materials.

[0003] During the high-temperature evaporation of the mother liquor, most purification equipment will add a stirring paddle to stir the mother liquor to speed up its evaporation efficiency. However, it is not easy for the purification equipment to seal and recover a large amount of evaporated steam in time with the stirring of the stirring paddle. The leakage of evaporated steam will affect the environment. Failure to recover the evaporated steam in time will affect the purification effect. In addition, most purification equipment is not easy to combine impurity filtration with mother liquor evaporation. Setting up a separate device to filter impurities in the mother liquor is not conducive to improving the overall efficiency of mother liquor purification. Utility Model Content

[0004] The purpose of the utility model is to provide a purification device for producing concrete water reducing agent to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

Detailed implementation mode

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0034] Embodiment 1, please refer to Figure 1-6 , in the embodiment of the present invention, a purification device for the production of concrete water reducer includes a heating tank 100. An evaporation tank 200 is fixedly arranged inside the heating tank 100. A support pipe 210 rotates inside the evaporation tank 200. A plurality of paddles 211 are fixedly arranged on the outer side of the support pipe 210. The top end of the evaporation tank 200 is connected and fixed with a steam delivery pipe 300. A shaft rod 310 rotates at one end of the steam delivery pipe 300. A plurality of fan blades 311 are fixedly arranged on the outer side of the shaft rod 310. The bottom end of the steam delivery pipe 300 is connected and fixed with a condensation tank 400. The condensation tank 400 is used for condensing low-boiling compounds such as ethers in the mother liquor of the water reducer. A drive assembly 500 is fixedly arranged on the top of the evaporation tank 200. The drive assembly 500 is used for driving the support pipe 210 and the shaft rod 310 to rotate simultaneously. A pumping assembly 600 is fixedly arranged on the top of the evaporation tank 200. The pumping assembly 600 includes a water pump body 610. The water suction end of the water pump body 610 is connected and fixed with a suction pipe 611. The suction pipe 611 is rotationally inserted into the support pipe 210. The water outlet end of the water pump body 610 is connected and fixed with a discharge pipe 620. A filter cartridge 700 is fixedly arranged on the top of the evaporation tank 200. The filter cartridge 700 is used for filtering the mother liquor falling from the discharge pipe 620.

[0035] Specifically, a support tube 210 is rotated inside the evaporation tank 200, and a plurality of blades 211 are fixed to the outside of the support tube 210. The driving component 500 drives the support tube 210 to rotate so that the mother liquor is in a stirring state, so that the mother liquor in the heated water state can quickly evaporate low-boiling point impurities. The evaporated impurity vapor is sealed and transported through the steam delivery pipe 300 to prevent steam from polluting the environment. The driving component 500 also drives the plurality of fan blades 311 inside the steam delivery pipe 300 to rotate. The rotation of the fan blades 311 increases the intensity of the steam suction of the steam delivery pipe 300, thereby enabling the steam delivery pipe 300 to suction steam in a timely manner. The water pump body 610 sucks the mother liquor into the filter cartridge 700 through the suction pipe 611 for filtration. The filtered mother liquor flows back to the evaporation tank 200 for evaporation, thereby realizing the combination of mother liquor evaporation and filtration, and further improving the overall efficiency of mother liquor purification.

[0036] like Figure 3 As shown, in this embodiment, a heating wire 110 is spirally arranged inside the heating tank 100, and the outside of the heating tank 100 is connected to a water exchange pipe 120 fixed with a built-in valve.

[0037] In this embodiment, the heating wire 110 is energized to generate heat, causing the heating tank 100 to heat the water therein. The evaporation tank 200 in the water bath heating state can heat the water reducer mother liquor to achieve evaporation of the mother liquor. The heating wire 110 heating is a prior art, and the specific principle of water bath heating is not described in detail. The water exchange pipe 120 facilitates the replacement of the water inside the heating tank 100. During normal use, the valve inside the water exchange pipe 120 is in a closed state, and the valve is opened when the water is changed.

[0038] like Figure 3 and Figure 6 As shown, in this embodiment, the top of the support tube 210 is rotatably connected to the steam delivery pipe 300, the bottom end of the support tube 210 is evenly provided with a plurality of through holes 212, and the inner bottom surface of the evaporation tank 200 is provided with a rotating groove rotatably connected to the support tube 210.

[0039] In this embodiment, the bottom end of the support tube 210 rotates on the bottom surface of the evaporator 200, and the top end of the support tube 210 rotates on the steam delivery pipe 300, thereby ensuring stable rotation of the support tube 210 within the evaporator 200. The through hole 212 facilitates the entry of the mother liquid within the evaporator 200 into the support tube 210, and the suction pipe 611 inserted into the bottom of the support tube 210 can aspirate the mother liquid.

[0040] like Figure 4As shown, in this embodiment, the drive assembly 500 includes a motor 510, a gear 2 520 and two pulleys, a gear 1 511 is fixed to the output end of the motor 510, the gear 2 520 is fixedly sleeved with the support tube 210, the gear 2 520 is meshed with the gear 1 511 for transmission, the two pulleys are fixedly connected to the support tube 210 and the shaft 310 respectively, and a synchronous belt is connected between the two pulleys for transmission.

[0041] In this embodiment, the output end of the motor 510 drives gear 1 511 to rotate, and gear 1 511 drives gear 2 520 to rotate to rotate the support tube 210, and the support tube 210 drives multiple blades 211 to rotate to achieve stirring of the mother liquor. The pulley on the outside of the support tube 210 drives another pulley to rotate through a synchronous belt, and the pulley drives the shaft 310 to rotate, so that the multiple fan blades 311 on the shaft 310 rotate, thereby increasing the intensity of the steam suction by the steam delivery pipe 300.

[0042] like Figure 5 As shown, in this embodiment, a filter screen 710 is fixed inside the filter cartridge 700, the bottom end of the discharge pipe 620 is connected and fixed to a hose 621 arranged above the filter screen 710, and the bottom end of the filter cartridge 700 is connected and fixed to a second water outlet pipe 720, which is connected and fixed to the evaporation tank 200.

[0043] In this embodiment, the water pump body 610 transports the mother liquor to the top of the filter screen 710 of the filter cartridge 700 through the hose 621. The filter screen 710 filters the mother liquor to facilitate the precipitation of impurities in the mother liquor. The filtered mother liquor still flows back to the interior of the evaporation tank 200 through the second outlet pipe 720 for further evaporation for standby use. The hose 621 can be removed from the filter cartridge 700, and then the impurities on the filter screen 710 can be cleaned so that the filter screen 710 can be reused. The purified mother liquor can still be transported to the outside through the water pump body 610 combined with the hose 621. The filter cartridge 700 can also add the mother liquor to be purified from the outside into the evaporation tank 200.

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, a top cover 130 is fixed to the top of the evaporation tank 200 , and a support column 140 is fixed to the top of the top cover 130 .

[0045] In this embodiment, the top cover 130 allows the steam generated during the evaporation process to be transported into the steam delivery pipe 300 , and two supporting plates are fixed on the top of the support column 140 , which are used to support and fix the water pump body 610 and the motor 510 .

[0046] like Figure 1 As shown, in this embodiment, a U-shaped block 320 is fixed to the outside of the steam delivery pipe 300, and the top of the U-shaped block 320 is rotatably connected to the shaft 310, thereby enabling the shaft 310 to rotate stably on the steam delivery pipe 300.

[0047] Example 2: Based on Example 1, the evaporated steam is condensed.

[0048] like Figure 3 As shown, in this embodiment, a spiral tube 410 is fixed to the inner top of the condensation tank 400, a partition 420 is fixed to the inner bottom of the condensation tank 400, and two connecting pipes 430 and a water outlet pipe 440 are fixed to the outside of the condensation tank 400.

[0049] In this embodiment, the steam delivery pipe 300 delivers high-temperature steam to the inside of the spiral tube 410, the external water pipe pumps cold water to a connecting pipe 430, and the other connecting pipe 430 draws cold water, so that the internal non-cold water of the condensation tank 400 is covered on the outside of the spiral tube 410, which facilitates the condensation of the steam inside the spiral tube 410. The condensed steam water falls to the bottom of the condensation tank 400 and is finally discharged to the outside from the water outlet pipe 440. The external water pipe can directly use the existing water pump to draw water to achieve it, which will not be described in detail here.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0051] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
