Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a polycarboxylic acid water-reducing agent reaction kettle. Background Art

[0002] In the modern concrete admixture production process, polycarboxylate water reducer occupies an important position due to its excellent performance and wide applicability. The key step in its production process is to carry out polymerization reaction in the reactor, which will generate chemical reaction heat and cause the temperature inside the reactor to rise significantly. When the heat in the reactor cannot be dissipated and controlled in a timely and effective manner, the water vapor generated by the reaction will escape from the material port of the reactor. When the steam escapes into the workshop environment, it will quickly condense into liquid water, thereby greatly increasing the air humidity in the workshop and causing a humid working environment.

[0003] The workshop humidity problem caused by the steam escape from the reactor will not only have a negative impact on the normal operation and life of the production equipment, such as accelerating the corrosion and aging of the equipment and affecting the insulation performance of the electrical equipment; it may also pose a potential threat to the safety and health of the operators, including increasing the risk of slips and falls, inducing occupational diseases, etc. Therefore, how to effectively prevent the steam from escaping due to the reaction heat during the use of the polycarboxylate water-reducing agent reactor, and thereby avoid the humidity of the workshop environment, is one of the technical problems that the industry needs to solve urgently.

[0018] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] Example 1

[0020] As attached Figure 1 As shown, a polycarboxylate water-reducing agent reactor comprises a stirring barrel 3 with a feeding port 1 and a liquid inlet pipe 2, and a condensing barrel 5 with a support leg 4; the upper end of the stirring barrel 3 is connected to a drainage pipe 6, and the drainage pipe 6 is connected to the side wall of the condensing barrel 5; the lower end of the condensing barrel 5 is provided with a drain valve 7; the upper end of the condensing barrel 5 is provided with an exhaust pipe 8; the stirring barrel 3 and the condensing barrel 5 are connected through the drainage pipe 6.

[0021] As a preferred technical solution of this embodiment, the condensation barrel 5 is cylindrical. After the air containing water vapor enters the condensation barrel 5, since the condensation barrel 5 has a large space, it is convenient for the air to be quickly cooled to achieve cooling of the water vapor. Obviously, condensation barrels of other suitable shapes can also be used.

[0022] As a preferred technical solution of this embodiment, a rainproof cap 11 is installed at the top of the exhaust pipe 8 to prevent rainwater from entering the condensation barrel 5 along the exhaust pipe 8 during the rainy season.

[0023] Example 2

[0024] As attached Figure 2 As shown, a polycarboxylate water-reducing agent reactor is provided, wherein a perforated plate 10 is arranged above the drainage pipe 6 in the condensation barrel 5, and the perforated plate can further capture atomized water droplets in the air to improve water recycling. The rest is basically the same as Example 1.

[0025] Example 3

[0026] As attached Figure 3 As shown, a polycarboxylate water-reducing agent reactor, wherein the drainage pipe 6 extends into the condensation barrel 5, and one end extending into the condensation barrel 5 is fixedly connected to a condensation hood 9. The condensation hood 9 is conical, and the open end is downward. The condensation hood 9 of this structure can effectively condense water vapor in the air, improve the recovery rate of steam, and further reduce water waste; the condensation hood is preferably made of metal material with good heat exchange. The rest is basically the same as Example 1.

[0027] The working process is as follows:

[0028] When in use, the exhaust pipe 8 should be long enough to extend beyond the top of the plant. Due to the temperature difference between the ground and the air, the channel formed by the mixing barrel 3, the drainage pipe 6, the condensation barrel 5 and the exhaust pipe 8 will form a chimney effect. The water vapor in the mixing barrel 3 is drained to the condensation barrel 5 for cooling and condensation, and then discharged from the exhaust pipe 8. The escape of steam in the reactor is effectively controlled, and the workshop humidity problem caused by the escape of steam is also solved. The utility model does not consume energy during the drainage and condensation of water vapor, so the operation and maintenance costs are relatively low.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
