Description
Technical Field
[0001] The utility model relates to a heating and heat preservation device for a concrete water reducing agent, in particular to a heating and heat preservation device for a concrete water reducing agent. Background Art
[0002] Concrete water reducer mother liquor is water reducer, which is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete. Water reducers are divided into ordinary water reducers and high-efficiency water reducers according to their water reducing and strengthening capabilities; they are divided into water-soluble sulfonates, polycyclic aromatic salts, and water-soluble resin sulfonates according to their constituent materials. Most water reducers are anionic surfactants, including lignin sulfonates, naphthalene sulfonate formaldehyde polymers, etc. After being added to the concrete mixture, the water reducer has a dispersing effect on the 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] When synthesizing water reducers, it is often necessary to insulate and stir the water reducer liquid mixed raw materials to facilitate the mixed synthesis of the water reducer. After the raw materials are stirred, the mixed raw materials need to be insulated for a certain period of time. During the insulation heating, the raw materials are usually heated by heating stirring blades or an internal heating plate. The heating element is often at a high temperature and in direct contact with the raw materials. When the raw materials are insulated, part of the raw materials may condense on the surface of the heating plate, affecting the synthesis of the raw materials. When the heating stirring blades are used to heat and insulate the raw materials, a motor is required to drive the stirring blades to rotate to increase the contact area between the stirring blades and the outside, which increases the power loss of the device.

DETAILED DESCRIPTION
[0024] The utility model is further described in detail below in conjunction with the accompanying drawings. Example
[0025] Reference Figure 1-4 The utility model discloses a heating and heat preservation device for concrete water reducer, comprising a water reducer synthesizer 1, which is mainly divided into three parts: a motor 11, a stirring rod 12 and a storage cylinder 13. The storage cylinder 13 can be made of metal materials such as stainless steel or heat-conducting alloy. Water is filled between the storage cylinder 13 and the inner wall of the heating barrel 21. A heating mechanism 2 is provided on the outer peripheral side of the storage cylinder 13, and the heating mechanism 2 performs heating and heat preservation treatment on the water reducer raw material in the storage cylinder 13.

A plurality of push plates 24 are relatively inclined and fixedly installed on the outer peripheral side of the top of the storage barrel 13.

A plurality of guide plates 25 are relatively fixedly installed on the inner wall of the storage barrel 13, and the plurality of guide plates 25 are set at different angles. The stirring rod 12 is set at the middle position between the guide plates 25. The setting of the annular groove 22 allows the water vapor to blow on the push plate 24 when it is discharged from the heating barrel 21, and the setting of the push plate 24 allows the water vapor to synchronously push the storage cylinder 13 to rotate when it is discharged. The setting of the ball 26 allows the push plate 24 to support and limit the top of the storage cylinder 13, and the setting of the guide plate 25 can constrain and limit the flow trajectory of part of the water reducer raw material in the storage cylinder 13.
[0026] A limiting mechanism 3 is provided on the top side of the storage cylinder 13, and the limiting mechanism 3 constrains the storage cylinder 13. The limiting mechanism 3 includes a support plate 31, which is threadedly inserted into the center position of the top of the heating barrel 21, and the motor 11 is fixedly installed at the center position of the top side of the support plate 31. A storage groove 32 with a T-shaped arrangement is provided on the top side of the support plate 31, and a main gear 33 is provided in the storage groove 32, and the output shaft of the motor 11 is inserted into the storage groove 32 and fixedly connected to the main gear 33. A plurality of circular grooves 34 with a T-shaped arrangement are relatively provided on the bottom side of the support plate 31, and the interior of each circular groove 34 is communicated with the interior of the storage groove 32. A transmission gear 35 is meshedly connected to the outer peripheral side of the main gear 33, and a rotating shaft 36 is fixedly inserted at the center position of the transmission gear 35, and the top end of the rotating shaft 36 extends to the outside of the storage groove 32 and rotates with the support plate 31 through a bearing. The bottom end of the rotating shaft 36 is inserted into the corresponding circular groove 34 and fixedly installed with an impeller 37. A piston rod 38 is slidably penetrated in the circular groove 34, and the piston rod 38 is located below the corresponding impeller 37. The top end of the stirring rod 12 is inserted into the storage groove 32 and fixedly connected with the main gear 33. A soft plate 310 is provided on the bottom side of the support plate 31, and one end of the piston rod 38 located outside the corresponding circular groove 34 is fixedly connected with the soft plate 310. The stirring rod 12 is rotatably connected with the soft plate 310 and the support plate 31. The top of the soft plate 310 is made of soft plastic, and the bottom of the soft plate 310 is made of rubber. A spring 39 is provided between the piston rod 38 and the inner wall of the corresponding circular groove 34, and the two ends of the spring 39 are respectively fixedly connected with the corresponding piston rod 38 and the inner wall of the corresponding circular groove 34. The arrangement of the main gear 33 and the transmission gear 35 enables the motor 11 to drive the impeller 37 to rotate more quickly when driving the stirring rod 12 to rotate. The arrangement of the circular groove 34, the impeller 37 and the piston rod 38 enables the stirring rod 12 to synchronously push the soft plate 310 toward the storage tube 13 when rotating at a high speed, thereby strengthening the resistance between the soft plate 310 and the opening of the storage tube 13. The arrangement of the spring 39 ensures that there is always a certain gap between the soft plate 310 and the opening wall of the storage tube 13 when the soft plate 310 is not subjected to thrust.
[0027] The implementation principle of the above embodiment is as follows: when the water reducer synthesizer 1 is synthesizing the water reducer raw material, when the water reducer raw material is gently stirred, the heating ring in the heating barrel 21 heats the water in the heating barrel 21, so that the water in the heating barrel 21 is maintained within a suitable temperature range, and the heat is transferred to the water reducer raw material in the storage barrel 13 through the storage barrel 13, so that the water reducer raw material is maintained within a suitable temperature range, and a large amount of heat is stored in the water in the heating barrel 21;
[0028] At the same time, when the motor 11 slowly drives the stirring rod 12 to rotate and stir the raw materials in the storage cylinder 13, it will first drive the main gear 33 to rotate, thereby driving the impeller 37 to rotate rapidly through the transmission gear 35 and the rotating shaft 36. The rotating impeller 37 pushes the air in the circular groove 34 downward, so that the pressure between the impeller 37 and the piston rod 38 increases, thereby partially pushing the piston rod 38 out of the circular groove 34 and pushing the soft plate 310 to move toward the storage cylinder 13, so that the bottom side of the soft plate 310 is aligned with the storage cylinder 13. The opening wall is tightly fitted, thereby blocking the top opening of the storage barrel 13, so that when the stirring rod 12 stirs the raw material, the raw material will not splash out of the storage barrel 13 from the opening of the storage barrel 13. At the same time, there is a strong resistance between the soft plate 310 and the top opening wall of the storage barrel 13, so that a great friction force is generated between the storage barrel 13 and the soft plate 310, thereby exerting a large restraining force on the storage barrel 13, so that when the raw material in the storage barrel 13 rotates, the adhesion between the raw material and the inner wall of the storage barrel 13 will not drive the storage barrel 13 to rotate together;
[0029] During the directional flow of the raw materials in the storage cylinder 13 due to the stirring of the stirring rod 12, due to the mutual interference between the raw materials and the guide plate 25, part of the raw materials can flow in different directions along the inclined surface of the guide plate 25, so that part of the raw materials are subjected to counter-mixing treatment, thereby accelerating the mixing of the raw materials;
[0030] After the stirring process of the water reducer in the storage barrel 13 is completed, the motor 11 stops rotating. According to the above-mentioned impeller 37, the impeller 37 stops rotating due to the loss of driving force, so that the thrust on the piston rod 38 disappears. At this time, the spring 39 pushes the piston rod 38 to reset, so that the soft plate 310 is separated from the opening wall of the storage barrel 13. At this time, the restraining force on the storage barrel 13 disappears. At this time, the water in the heating barrel 21 still maintains the set temperature to maintain the temperature of the raw materials in the storage barrel 13, and the raw materials in the storage barrel 13 are kept warm. With the evaporation of the heating barrel 21, the water vapor is discharged from the annular groove 22, and the water vapor will push on the push plate 24 during the flow and discharge process, thereby driving the storage barrel 13 to rotate, so that the guide plate 25 in the storage barrel 13 slowly moves the external raw materials in the storage barrel 13.
[0031] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
