Description

Technical Field

[0001] The utility model relates to the technical field of separation devices, and particularly relates to a device for efficiently separating additive precipitate particles from water Background Technique

[0002] In the polyethylene granulation technology, the polyethylene particle water needs to be cooled by circulation. The prior art uses a finned heat exchanger to cool the particle water. Since a large amount of additive precipitates will precipitate after the particle water is cooled, this additive precipitate will adhere to the surface of the finned heat exchanger. However, the heat exchanger needs to be maintained by manual high-pressure water flushing every once in a while to remove the additive precipitate on the surface of the heat exchanger. The operation is cumbersome and requires shutdown operation, which affects the work efficiency Content of the Utility Model

[0003] In order to solve the technical problems mentioned in the above background technique, the utility model provides a device for efficiently separating additive precipitate particles from water, and the technical scheme adopted is as follows

[0004] It includes an extruder particle water chamber, and is characterized in that the extruder particle water chamber is connected with an air cooler through a pipeline, the air cooler is connected with an air pump through a pipeline, a water storage tank is arranged downstream of the air cooler, and the interior of the water storage tank is divided into several chambers by several partitions. The height of the partitions decreases one by one from right to left. A skimmer is arranged above each chamber, and the bottom of the skimmer just touches the upper part of the particle water surface in the chamber. A pipeline is arranged at the bottom of the air cooler and the pipeline extends into the rightmost chamber. An inclined pipe is connected to the rear of each chamber and the front end of the inclined pipe is higher than the rear end. One-third of the pipe orifice of the inclined pipe is immersed in the particle water in the chamber. A collection tank is arranged downstream of the water storage tank, and the other end of the inclined pipe extends into the collection tank

[0005] Preferably, the skimmer includes a motor, a stirring rod is arranged on the motor, and paddle blades are arranged on the stirring rod, and the bottom of the paddle blades just touches the upper part of the particle water surface in the chamber

[0006] Preferably, a sewage discharge pipe is arranged at the bottom of each chamber, one end of the sewage discharge pipe extends into the collection tank, and a sewage discharge valve is arranged on the sewage discharge pipe

[0008] Preferably, the water pump is connected with a particle water heater through a pipeline, and the particle water heater is connected with the extruder particle water chamber through a pipeline

[0009] The utility model has the following advantages: The granular water in the granular water chamber of the extruder enters the rightmost chamber in the water storage tank after being cooled by the air cooler. The granular water in the rightmost chamber flows from right to left and successively flows into the left chambers. Since the height of the partition gradually decreases from right to left, the water level height in each chamber gradually decreases from right to left. Additives are precipitated on the upper surface of the granular water in each chamber and the water level of the granular water in the chamber gradually rises. At the same time, the skimmer rotates. When the granular water in each chamber reaches the uppermost part of each chamber, the liquid level of the granular water submerges one-third of the lower part of the inclined tube. The granular water enters the inclined tube. At this time, the bottom of the skimmer just contacts the upper part of the granular water in each chamber, and the additives floating on the granular water are skimmed into the inclined tube as much as possible by rotation and then discharged into the collection tank. The utility model enables the cooled granular water to pass through the three-stage chambers of the water storage tank, and the skimmer skims the precipitated additives floating on the granular water into the collection tank, eliminating the need for equipment cleaning and maintenance and greatly improving the production efficiency.

Detailed Embodiment

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0014] Embodiment

[0015] As Figure 1-2 shown:

[0016] The utility model provides a device for efficiently separating additive precipitate particles from water, which comprises a granule water chamber 1 of an extruder. The granule water chamber 1 of the extruder is connected with an air cooler 2 through a pipeline. The granule water in the granule water chamber 1 of the extruder enters the air cooler 2 through the pipeline. An air pump 3 is connected to the air cooler 2 through a pipeline. Air is made to enter the air cooler 2 through the air pump 3 and then come out of the air cooler 2. A water storage tank 4 is arranged downstream of the air cooler 2. After the granule water is cooled by the air cooler 2, it enters the rightmost chamber 6 in the water storage tank 4 through a pipeline. The interior of the water storage tank 4 is divided into several chambers 6 by several partition plates 5. The height of the partition plates 5 decreases one by one from right to left. A skimmer 7 is arranged above each chamber 6. The bottom of the skimmer 7 just touches the upper part of the granule water surface in the chamber 6. Through multiple chambers 6 and multiple skimmers 7, the skimmer 7 can more efficiently skim the additive precipitates in the granule water in multiple chambers 6. A pipeline is arranged at the bottom of the air cooler 2 and the pipeline extends to the rightmost chamber 6. An inclined pipe 8 is connected to the rear of each chamber 6 and the front end of the inclined pipe 8 is higher than the rear end. So that the granule water and the additive precipitates in the granule water can flow downward after entering the inclined pipe 8. The cooled granule water first enters the rightmost chamber 6 in the water storage tank 4. One third of the pipe orifice of the inclined pipe 8 is immersed in the granule water in the chamber 6, so that a small part of the granule water in the chamber 6 enters the inclined pipe 8 and then enters the collection tank 9 through the inclined pipe 8. A collection tank 9 is arranged downstream of the water storage tank 4. The other end of the inclined pipe 8 extends into the collection tank 9.

[0017] It should be noted that the interior of the air cooler 2 is a hollow structure. The external air flow enters the outer wall sandwich of the air cooler 2 and then is pumped away by the air pump 3. For reference, see Figure 1 .

[0018] The skimmer 7 comprises a motor 10. A stirring rod 11 is arranged on the motor 10. A paddle 12 is arranged on the stirring rod 11. The bottom of the paddle 12 just touches the upper part of the granule water surface in the chamber. The stirring rod 11 is driven to rotate by the motor, and the paddle 12 is driven to rotate by the stirring rod 11. The paddle 12 skims the additive precipitates in the granule water into the inclined pipe 8.

[0019] A sewage discharge pipe 13 is arranged at the bottom of each chamber 6. One end of the sewage discharge pipe 13 extends into the collection tank 9. A sewage discharge valve 14 is arranged on the sewage discharge pipe 13. The granule water in each chamber 6 can be discharged into the collection tank 9 by opening the sewage discharge valve 14. Some precipitates will be carried in the granule water.

[0020] A filter 15 and a water pump 16 are connected to the left part of the water storage tank 4 through pipelines. The utility model adds the filter 15 as a device for assisting in removing the additive precipitates in the granule water. Since a lot of additive precipitates have been removed before, the filter 15 does not need to be frequently cleaned when filtering the additive precipitates in the granule water at this time.

[0021] The water pump 16 is connected with a granular water heater 17 through a pipeline. The granular water heater 17 is connected with the granular water chamber 1 of the extruder through a pipeline. The circulating granular water enters the granular water heater 17 through the pipeline, is heated and then newly supplied to the granular water chamber 1 of the extruder for use.

[0022] The working principle of the present utility model is as follows:

[0023] The high-temperature granular water coming out of the granular water chamber 1 of the extruder enters the air cooler 2 through the pipeline. After being cooled by the air cooler 2, it enters the chambers 6 on the left and right sides of the water storage tank 4. Since the height of the partition plate 5 gradually decreases from right to left, the granular water in the chamber 6 flows from right to left through the upper part of the partition plate 5. Additives are precipitated on the upper surface of the granular water in each chamber 6, and the water level of the granular water in the chamber 6 gradually rises. At the same time, the motor 10 drives the stirring rod 11 to rotate, and the stirring rod 11 drives the paddle 12 to rotate. When the granular water in each chamber 6 reaches the uppermost part of each chamber 6, the liquid level of the granular water submerges one-third of the lower part of the inclined pipe 8, and the granular water enters the inclined pipe 8. At this time, the skimming paddle 12 just contacts the upper part of the granular water in each chamber 6. By the rotation of the paddle 12, the additives floating on the granular water are skimmed into the inclined pipe 8 along with the granular water and are collected in the collection tank 9.

[0024] The present utility model is simple to operate and convenient to use, and is suitable for comprehensive promotion and application. Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
