Description

Technical Field

[0001] The utility model relates to the technical field of production of redispersible latex powder, in particular to an intermediate transition bin for production of redispersible latex powder. Background Art

[0002] In the production process of redispersible latex powder, the intermediate transition bin is a key component. It is mainly used to temporarily store the latex powder that has been preliminarily treated but has not yet reached the final dry state before spray drying. The intermediate transition bin plays a connecting role in the production process of redispersible latex powder. It is closely connected with the upstream latex preparation and preliminary treatment links to ensure that the latex can be promptly and evenly transported to the spray dryer for drying after preliminary treatment. At the same time, it is also closely connected with the downstream spray drying link to provide a stable and continuous supply of latex to the spray dryer.

[0003] When a general transition bin is in use, the latex adhered to the side wall cannot be effectively utilized, thereby reducing the effective storage capacity of the storage tank. If the adhered latex deteriorates or is contaminated during storage, it will affect the quality of the latex powder produced subsequently.

[0004] Therefore, it is particularly important to design an intermediate transition bin for the production of redispersible latex powder to change the above-mentioned technical defects and improve overall practicality. Utility Model Content

A limit block 304 and a connecting block 303 are connected to a fixed tube 4. A fixed groove 401 is provided inside the fixed tube 4. A plurality of compression springs 402 are provided on the inner side wall of the fixed groove 401. A scraper 403 is provided inside the fixed groove 401. A fixed plate 404 is provided on the top of the fixed tube 4. A cover cylinder 101 is provided on the top of the storage tank 2. A filling port 102 is provided through the cover cylinder 101. A discharge pipe 103 is provided at the bottom of the storage tank 2. A flow meter 104 is provided outside the discharge pipe 103. A solenoid valve 105 is provided on one side of the flow meter 104.

[0027] The inner bottom surface of the storage tank 2 is provided with a temperature sensor, the inner side wall of one side of the storage tank 2 is provided with a liquid level sensor, the inner part of the discharge pipe 103 is provided with a viscosity sensor, a battery and a control panel are provided on the support base 1, the control panel and the battery are electrically connected, the control panel and the motor 203, the flow meter 104, the solenoid valve 105, the temperature sensor, the liquid level sensor, and the viscosity sensor are electrically connected to facilitate monitoring the state of the latex powder during storage, the motor 203 and the stirring shaft 201 are key-connected, the connecting ring 3 and the stirring shaft 201 are fixedly connected, and a rubber The connecting tube 302 is provided with a card slot for matching with the card slot, and the connecting tube 302 is provided with an avoidance slot for matching with the limit block 304, so as to fix the position of the fixed tube. The fixed slot 401 is matched with the scraper 403, and the scraper 403 can slide between the fixed tubes 4. The fixed plate 404 is connected to the fixed tube 4 by bolts to prevent a large amount of latex powder from entering the interior of the fixed tube 4. A heater is provided on the outside of the storage tank 2, and the heater is connected to a heating plate. The heating plate is arranged on the outside of the storage tank 2 along the height thereof, so as to control the temperature of the latex powder and maintain the best state.

[0028] The working process of the utility model is as follows: when using the intermediate transition bin for the production of redispersible latex powder, first the latex liquid undergoes preliminary processing, such as filtering and heating, and then the latex powder raw material is added to the storage tank 2 through the filling port 102. At this time, the temperature sensor and the liquid level sensor respectively monitor the temperature and liquid level inside the storage tank 2 to ensure that the raw materials are in suitable storage conditions. Once the raw materials are added, the motor 203 starts to work, and drives the stirring rod 202 to rotate through the stirring shaft 201 to evenly stir the latex powder raw materials. During the stirring process, the scraper 403 is acted upon by the compression spring 402 in the fixed groove 401, and is always in close contact with the inner wall of the storage tank 2. As the motor rotates, it continuously scrapes the inner side wall of the storage tank 2 to prevent the raw materials from attaching during the stirring process. On the tank wall, when discharging is required, the operator controls the solenoid valve 105 to open through the control panel, and the latex powder flows out through the discharge pipe 103. At the same time, the flow meter 104 monitors the discharge flow in real time to ensure the accuracy of the discharge amount. If the viscosity of the latex powder does not meet the requirements, the viscosity sensor will send a signal to the control panel. The operator can adjust the stirring speed or temperature as needed. The fixed tube 4 can be slightly rotated to disengage the limit block 304 from the avoidance groove and separate the rubber block from the groove. Then the fixed tube is taken out, the fixed plate 404 is removed by bolts, and the scraper 403 is pulled out upward for cleaning or replacement. It can be replaced with a cleaning brush to facilitate the later cleaning of the inner side wall, or it can be replaced after the scraper 403 is worn.
