Technical Field

[0001] The present invention relates to the technical field of polycarboxylate water reducers, and particularly to a sterile fermentation device for polycarboxylate water reducers. Background Art

[0002] Polycarboxylate water reducer is a concrete admixture with a comb-shaped structure. It disperses cement particles through electrostatic repulsion and steric hindrance, thereby reducing the water consumption of concrete mixing, enhancing the performance of concrete, and improving the workability. It is widely used in fields such as precast components, high-performance concrete projects, and commercial concrete production.

[0003] Due to the good and stable properties of polycarboxylate water reducers, they are widely used in concrete projects. The main purpose is to reduce the mixing water consumption, improve the workability of concrete, and enhance the mechanical properties of concrete to meet the requirements of different projects for the quality and performance of concrete. When a large amount of polycarboxylate water reducer needs to be put into use, a sterile fermentation device for polycarboxylate water reducers is required.

[0004] However, there are the following deficiencies in the existing sterile fermentation device for polycarboxylate water reducers: Currently, the sterile fermentation devices for polycarboxylate water reducers on the market all use chemical additives to sterilize the raw materials of polycarboxylate water reducers and then carry out blending production. However, the extensive use of chemical additives not only increases the cost but also easily affects the raw material composition and purity of polycarboxylate water reducers, resulting in the impact on the performance of polycarboxylate water reducers in subsequent production reactions, leading to a decline in the quality of polycarboxylate water reducers, and further affecting the unqualified quality of the produced concrete.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the polycarboxylate superplasticizer is fermented in the present invention, the electric telescopic rod is started to raise the lifting frame fixed at the top, driving the DC motor and the top cover, so that the evaporation pan composed of the top cover and the bottom cover is opened. The raw materials are put into the material basket in the bottom cover. Then the electric telescopic rod is started again to lower the top cover and the bottom cover to fit. It is sealed by the sealing ring of the top cover and the sealing groove of the bottom cover. The heating coil inside the top cover is started to heat. The temperature is observed according to the pressure gauge on the top cover. After reaching a certain value, the temperature is maintained by the controller. After the sterilization time is up, the DC motor on the top of the top cover is started. By engaging the connecting rod A and the connecting rod B, the dial plate on the connecting rod B and the composite stirring structure are driven to rotate. The dial plate stirs the materials in the material basket, so that the materials fall from the holes on the basket to the bottom of the bottom cover and are dispersed and stirred by the composite stirring structure, and the raw materials are fermented. At the same time, the internal temperature can be maintained at a sterilizable temperature to kill residual bacteria and microorganisms. After the fermentation is over, the solenoid valve at the bottom of the bottom cover is opened, and the raw materials flow into the sterile finished product barrel through the connecting pipe. To ensure the sterility of the pipeline, the connecting pipe connects the material basket and the vacuum pump, and the high-temperature air flow inside the top cover and the bottom cover is introduced into the connecting pipe and the solenoid valve to raise their temperature and prevent bacteria from growing. Thus, the state of sterility is achieved during the fermentation of the polycarboxylate superplasticizer, avoiding the cost increase caused by the large use of chemical additives and affecting the raw material composition and purity of the polycarboxylate superplasticizer, avoiding affecting the performance of the polycarboxylate superplasticizer in subsequent production reactions, and at the same time avoiding the problem that the quality of the polycarboxylate superplasticizer decreases and affects the quality of the produced concrete not meeting the standards.

[0018] 2. For the equipment of the present invention, to prevent the evaporation pan composed of the top cover and the bottom cover from leaking air due to high temperature and high pressure, resulting in the internal temperature not reaching the standard, a stepping motor is installed on the support column at the top of the base.

Two fastening slide bars on the fastening turntable, one rotates in the limit rotation hole of the bottom cover, and the other slides along the fastening slideway on the top cover. Since the distance between the two fastening slide bars is fixed, with its sliding, the reinforcement and sealing of the top cover and the bottom cover are realized, thereby preventing air leakage between the top cover and the bottom cover, resulting in the situation that the internal temperature does not reach the standard.

[0023] The effect achieved by the entire Example 1 is as follows: Start the electric telescopic rod 301, and the lifting frame 304 fixed at the top will slowly rise immediately. The DC motor 305 and the top cover 206 connected thereto are also driven to move upward synchronously. As the top cover 206 rises, the evaporation pan formed by the top cover 206 and the bottom cover 209 will be opened accordingly. At this time, various raw materials of polycarboxylate water reducer for fermentation are successively placed into the material basket 401 inside the bottom cover 209. After the raw materials are placed, start the electric telescopic rod 301 again to drive the top cover 206 to descend smoothly until the top cover 206 fits tightly with the bottom cover 209. At this time, the sealing ring at the edge of the top cover 206 just fits into the sealing groove opened on the bottom cover 209, completing the sealing process.

[0025] The effect achieved by the entire Example 2 is as follows: Turn on the heating coil 303 installed inside the top cover 206 to quickly fill the inside of the evaporation pan with heat. Pay attention to the internal temperature change through the pressure gauge 210. When the temperature climbs to the set value, the controller 8 automatically intervenes to precisely control the power of the heating coil 303 to maintain the current temperature constant. When the effective sterilization duration is reached, start the DC motor 305 fixed to the top of the top cover 206. The motor rotates to drive the connecting rod A 306. Due to the tight engagement between the connecting rod A 306 and the connecting rod B 402, the connecting rod B 402 is driven to rotate together. The baffle 403 and the composite stirring structure 404 fixed on the connecting rod B 402 also start to operate. The baffle 403 is attached to the bottom of the basket body inside the material basket 401 and continuously stirs along the circumferential direction, gradually pushing the materials in the material basket 401 to the preset holes on the basket body. The materials then fall from the holes to the bottom of the bottom cover 209.

[0026] Example 3, according to Figure 5 、 Figure 6 and Figure 7As shown, a sealing ring is fixed to the bottom of the top cover 206. The size of the sealing ring is consistent with the size of the sealing groove formed on the bottom cover 209. The bottom of the bottom cover 209 communicates with a sterile sampling agent bottle 408. The fastening slide bar 205 is slidably connected to the fastening slideway 208, and another fastening slide bar 205 is rotatably connected to the limit rotating hole 207. A pressure gauge 210 is fixedly connected to the top of the top cover 206. The inner size of the fastening slideway 208 is slightly larger than the size of the fastening slide bar 205. A rotating pipe fitting is fixed to the inside of the material basket 401. The connecting B rod 402 is rotatably connected to the material basket 401 through the rotating pipe fitting.

A plurality of support columns 6 are fixedly connected to the bottom of the support 201, and the plurality of support columns 6 are fixedly connected to the bottom plate 7. A controller 8 is fixedly connected to the top of the bottom plate 7.

[0027] The effect achieved by the entire Embodiment 3 is as follows: After the vacuum pump 503 is turned on, using its powerful suction force, the high-temperature airflow inside the top cover 206 and the bottom cover 209 is guided into the connecting pipe 407 and the solenoid valve 405. The continuous influx of high-temperature airflow causes the temperature inside the connecting pipe 407 and the solenoid valve 405 to rise rapidly, creating a high-temperature environment that is not conducive to the growth of bacteria and microorganisms, effectively preventing bacteria and microorganisms from multiplying in the pipeline system, and ensuring the sterility of the entire transportation process.

[0028] The working principle of the whole device is as follows: When polycarboxylate superplasticizer fermentation is required, first start the electric telescopic rod 301 to drive the lifting frame 304 fixed at the top to rise. When the lifting frame 304 rises, it drives the DC motor 305 and the top cover 206 to rise together. At this time, the evaporation pan composed of the top cover 206 and the bottom cover 209 opens as the top cover 206 rises. Then, put each raw material of polycarboxylate superplasticizer to be fermented into the material basket 401 inside the bottom cover 209. At this time, start the electric telescopic rod 301 again to drive the top cover 206 to descend until the top cover 206 fits with the bottom cover 209. At this time, the sealing ring of the top cover 206 fits with the sealing groove opened on the bottom cover 209 for sealing. Then, start the heating coil 303 arranged inside the top cover 206 to heat its interior. At this time, observe the internal temperature through the pressure gauge 210 on the top cover 206. When it reaches a certain temperature, make the heating coil 303 maintain the temperature through the controller 8. After reaching the effective sterilization time, the DC motor 305 fixed on the top of the top cover 206 drives the dial 403 fixed on the connecting rod B 402 and the composite stirring structure 404 to rotate through the engagement of the connecting rod A 306 and the connecting rod B 402. Since the connecting rod B 402 rotates inside the material basket 401, at this time, the dial 403 rotates along the bottom inside the material basket 401, and the materials on the material basket 401 are stirred until they are stirred into the holes opened on the material basket 401. At this time, the materials fall into the bottom of the bottom cover 209 from the holes and are dispersed and stirred by the rotating composite stirring structure 404. At this time, the polycarboxylate superplasticizer raw materials ferment, and during this process, the internal temperature is always in a state where sterilization can be carried out, sterilizing the remaining bacteria and microorganisms inside the dispersed polycarboxylate superplasticizer raw materials. When the fermentation time is over, the solenoid valve 405 connected to the bottom of the bottom cover 209 opens, and the raw materials flow into the sterile finished product barrel 406 through the connecting pipe 407 along the opened solenoid valve 405. In order to keep the raw materials sterile in the pipeline, it is connected to the material basket 401 through the connecting pipe 501, and then through the connecting pipe 501 and the vacuum pump 503 at the bottom, the high-temperature air flow inside the top cover 206 and the bottom cover 209 is driven to flow into the connecting pipe 407 and the solenoid valve 405, so that the temperature in the connecting pipe 407 and the solenoid valve 405 rises to prevent the growth of bacteria and microorganisms.

[0029] To prevent the evaporation pan composed of the top cover 206 and the bottom cover 209 from leaking air due to high temperature and high pressure, resulting in the internal temperature not meeting the standard, the stepper motor 202 is fixed on the bracket 201 at the top of the pillar 6 through the pillar 6 at the top of the base 1. The connecting plate 203 is driven to rotate by the stepper motor 202. Since the connecting plate 203 is designed with connecting rods on the side and is connected to the fastening turntable 204 through this connecting rod, at this time, one of the two fastening sliding rods 205 on the fastening turntable 204 rotates in place in the limit rotation hole 207 opened on the bottom cover 209, and the other slides along the fastening slideway 208 opened on the top cover 206. Since the distance between the two fastening sliding rods 205 cannot be changed, when one of them slides farther and farther along the fastening slideway 208, the effect of strengthening and sealing the top cover 206 and the bottom cover 209 is achieved.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
