Description

Technical Field

[0001] The present invention relates to the technical field of centralized liquid supply and purification tanks, and in particular to a carrageenan production water recovery and treatment device and method. Background Art

[0002] Carrageenan is a natural polysaccharide hydrophilic gel extracted from marine red algae. It is widely used in food, medicine, daily chemical industry, biochemistry, textile printing and other fields. In the process of recycling carrageenan waste liquid, the carrageenan waste liquid needs to be filtered and treated.

[0003] Existing carrageenan production water recovery and treatment devices mostly use filter screens to filter impurities when treating carrageenan wastewater. However, the filter screens are easily clogged by impurities, resulting in the filter screens not being able to be used for a long time. Although scraping is used to clean impurities in the existing technology, some impurities slightly larger than the mesh holes are difficult to scrape away, which affects the efficiency of carrageenan wastewater treatment.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing carrageenan production water recovery and treatment devices on the market.

[0016] A method for using a carrageenan production water recovery and treatment device comprises the following steps:

[0017] S1. The collected carrageenan waste liquid is transported to the top of the liquid guide housing through the liquid inlet pipe. The carrageenan waste liquid is guided to the top of the filter screen through the liquid guide housing. The mesh size of the three upper filters gradually decreases from top to bottom, and the mesh size of the bottom filter screen is consistent with the mesh size of the second-to-last filter screen. The filter screen is used to filter out impurities. During the filtering process, the rotating rod is rotated to cause the scraper to scrape off impurities on the top of the filter screen, so that the impurities move to the drop hole and are collected by the receiving housing. Frequent manual cleaning of the filter screen is unnecessary.

[0018] S2. The water level and pH value of the carrageenan waste liquid in the centralized tank can be detected by the water level sensor and the pH sensor. When the pH value of the carrageenan waste liquid is detected to be lower than the set value range, the controller starts one of the water pumps to transport the solution with a higher pH value to the centralized tank. When the pH value of the carrageenan waste liquid is higher than the set value range, the other water pump is started to transport the solution with a lower pH value in the water collection chamber to the centralized tank, thereby achieving the effect of adjusting the pH value of the carrageenan waste liquid to an appropriate range (e.g., 6.0-7.0) for subsequent treatment.

[0019] S3. After the work is completed, a small amount of impurities will be stuck in the mesh. When the round block rotates, it will drive the suction plate to move in a circle. At this time, the external control switch is turned on to start the vacuum pump, so that negative pressure is generated in the central pipe, air guide pipe, rotating rod, and suction plate. There is a certain gap between the suction plate and the mesh, so that the gas is sucked in from the suction hole. When impurities enter the interior of the fixed box, the dust filter in the fixed box can filter the impurities to prevent the impurities from being sucked into the vacuum pump. During adsorption, the knocking block will knock on the filter to loosen the impurities in the mesh, so that the impurities in the mesh can be cleaned.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention provides a filtering unit to transport the collected carrageenan waste liquid to the top of the liquid guide shell through a liquid inlet pipe, and guides the carrageenan waste liquid to the top of the filter screen through the liquid guide shell. The mesh size of the three upper filters among the four filters gradually decreases from top to bottom, and the mesh size of the bottom filter screen is consistent with the mesh size of the second-to-last filter screen. The filter screen is used to filter impurities. During the filtration process, the rotating rod is rotated to cause the scraper to scrape off the impurities on the top of the filter screen, so that the impurities move to the drop hole and are collected by the receiving shell, without the need for frequent manual cleaning of the filter screen.

[0022] 2. The present invention sets a collection unit. When scraping impurities, a small amount of impurities will be stuck in the mesh. When the round block rotates, it will drive the suction plate to move in a circle. At this time, the external control switch is started to start the air pump, so that negative pressure is generated in the central pipe, the air guide pipe, the rotating rod, and the suction plate. There is a certain gap between the suction plate and the mesh, so that the gas is sucked in from the suction hole. When impurities enter the interior of the fixed box, the dust filter in the fixed box can filter the impurities to prevent the impurities from being sucked into the suction pump. During adsorption, the knocking block will knock on the filter to loosen the impurities in the mesh, so that the impurities in the mesh can be cleaned.

[0023] 3. The present invention is provided with an infusion mechanism, and the water level sensor and the pH sensor can detect the water level and pH value of the carrageenan waste liquid in the collection box. When the pH value of the carrageenan waste liquid is detected to be lower than the set numerical range, the controller starts one of the water pumps to transport the solution with a higher pH value to the collection box. When the pH value of the carrageenan waste liquid is higher than the set numerical range, the other water pump is started to transport the solution with a lower pH value in the water collection chamber to the collection box, thereby achieving the effect of adjusting the pH value of the carrageenan waste liquid, and adjusting the pH value of the carrageenan waste liquid to an appropriate range (such as 6.0~7.0) for subsequent treatment.

[0039] As a further limitation of the processing mechanism 2 of the present invention, the filtering unit 21 includes a circular ring 2101 fixedly connected to the inner wall of the central box 11, the number of the circular rings 2101 is two, the inner wall of the circular ring 2101 is fixedly connected with a filter screen 2102, the inner cavity of the filter screen 2102 is rotatably connected with a rotating rod 2103, the surface of the rotating rod 2103 is fixedly connected with two round blocks 2104, the surface of the round block 2104 is fixedly connected with a scraper 2105 in contact with the top of the filter screen 2102, the number of the scrapers 2105 is several, the surface of the rotating rod 2103 is also rotatably connected to the inner wall of the central box 11, the top of the filter screen 2102 is provided with a drop hole 2106, and the lower part of the drop hole 2106 is connected with a material guide pipe 2107, and the inner cavity of the central box 11 is fixedly connected with a liquid guide pipe. Shell 2108, the surface of the rotating rod 2103 is fixedly connected with stirring blades 2109, and the number of stirring blades 2109 is several. By setting the filtering unit 21, the collected carrageenan waste liquid is transported to the top of the liquid guide shell 2108 through the liquid inlet pipe 12, and the carrageenan waste liquid is guided to the top of the filter screen 2102 through the liquid guide shell 2108. The mesh size of the upper three of the four filter screens 2102 gradually becomes smaller from top to bottom, and the mesh size of the bottom filter screen 2102 is consistent with the mesh size of the second-to-last filter screen 2102. The filter screen 2102 is used to filter impurities. During the filtration process, the rotating rod 2103 is rotated to make the scraper 2105 scrape off the impurities on the top of the filter screen 2102, so that the impurities move to the drop hole 2106 for discharge.

[0040] One end of the rotating rod 2103 passes through the bottom of the central box 11 and is fixedly connected to the transmission shaft 2110. The two transmission shafts 2110 are connected by a belt 2111. The bottom of the central box 11 is fixedly connected to a connecting rod 2112.

The handle 2116 can be pulled to make the connecting plate 2115 and the material receiving shell 2114 detach from the inner cavity of the outer shell 1, thereby achieving the effect of collecting impurities.

[0042] The specific implementation of this embodiment is as follows: the collected carrageenan waste liquid is transported to the top of the liquid guide shell 2108 through the liquid inlet pipe 12, and the carrageenan waste liquid is guided to the top of the filter screen 2102 through the liquid guide shell 2108. The mesh size of the three upper filters 2102 gradually decreases from top to bottom, and the mesh size of the bottom filter screen 2102 is consistent with the mesh size of the second-to-last filter screen 2102. The filter screen 2102 is used to filter the impurities in the carrageenan waste liquid.

The filter screen 2102 is filtered through the filter element 2104 and the filter element 2105 is moved to the filter element 2102 to be filtered. The filter screen 2102 is filtered through the filter element 2104 and the filter element 2105 is moved to the filter element 2102 to be filtered.

[0043] Example 2: Please refer to Figures 1-12 The present invention provides a technical solution: a carrageenan production water recovery and treatment device, and the present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0044] As a further limitation of the processing mechanism 2 of the present invention, the collecting unit 22 includes an absorption plate 2201 fixedly connected to the surface of the round block 2104, and an absorption hole 2202 is opened at the bottom of the absorption plate 2201. The number of the absorption holes 2202 is several, and the surface of the rotating rod 2103 is rotatably connected to the rotating block 2203, and the surface of the rotating block 2203 is fixedly connected to the air guide pipe 2204. The inner wall of the centralizing box 11 is fixedly connected to the centralizing pipe 2205, and one end of the air guide pipe 2204 is communicated with the centralizing pipe 2205. One end of the centralizing pipe 2205 passes through the centralizing box 11 and extends to the outside of the shell 1. One end of the centralizing pipe 2205 is fixedly connected to the fixed box 2206, and one side of the fixed box 2206 is fixedly connected to the air pump 2207. The air extraction end of the air pump 2207 is fixedly connected to the bottom of one side of the fixed box 2206, and the inner cavity of the fixed box 2206 is installed with a dust filter 2217 by bolts. The central pipe 2205, the air guide pipe 2204, the rotating rod 2103, the suction plate 2201 and the suction hole 2202 are connected. By setting the collection unit 22, when the impurities are scraped, a small amount of impurities will be stuck in the mesh. When the round block 2104 rotates, it will drive the suction plate 2201 to move in a circle. At this time, the external control switch is started to start the air pump 2207, so that negative pressure is generated in the central pipe 2205, the air guide pipe 2204, the rotating rod 2103 and the suction plate 2201, so that the gas is sucked in from the suction hole 2202. When impurities enter the interior of the fixed box 2206, the dust filter 2217 in the fixed box 2206 can filter the impurities to prevent the impurities from being sucked into the suction pump 2207, so that the impurities in the mesh can be cleaned. The dust filter 2217 is installed by bolts and can be replaced or cleaned.

[0045] The inner cavity of the suction plate 2201 is slidably connected with a moving block 2208, and the bottom of the moving block 2208 is fixedly connected with a knocking block 2209. The number of knocking blocks 2209 is several. The inner wall of the suction plate 2201 is fixedly connected with a telescopic rod 2210. The surface of the telescopic rod 2210 is movable with a spring 2211. One end of the spring 2211 is fixedly connected to the inner wall of the suction plate 2201, and the other end of the spring 2211 is fixedly connected to the top of the moving block 2208. By setting the moving block 2208 and the knocking block 2209 , the telescopic rod 2210 and the spring 2211 are used in combination. When the suction plate 2201 is used for circular movement, the moving block 2208 is moved upward, so that the moving block 2208 drives the telescopic rod 2210 to contract, and the spring 2211 is compressed. When the squeezing of the moving block 2208 is cancelled, the force deformation of the spring 2211 will drive the moving block 2208 to move downward, so that the knocking block 2209 knocks on the filter screen 2102, thereby achieving the effect of loosening the impurities in the mesh.

[0046] Grooves 2212 are provided on one side of the suction plate 2201 and one side of the scraper 2105. The bottom of the moving block 2208 is fixedly connected to the extrusion block 2213. The bottom of the extrusion block 2213 is set at an angle. The inner wall of the ring 2101 is fixedly connected to the cylinder 2214 used in conjunction with the extrusion block 2213. There are several cylinders 2214. By setting the groove 2212, the extrusion block 2213 and the cylinder 2214 in conjunction with each other, when the suction plate 2201 moves in a circular motion, the cylinder 2214 will be located in the groove 2212 to squeeze the extrusion block 2213, thereby achieving the effect of driving the moving block 2208 to move upward.

[0047] The inner wall of the round block 2104 and the inner wall of the rotating block 2203 are fixedly connected with a first sealing ring 2215. The inner wall of the first sealing ring 2215 is in close contact with the surface of the rotating rod 2103. The surface of the rotating rod 2103 is fixedly connected with a second sealing ring 2216. There are several second sealing rings 2216. The surface of the second sealing ring 2216 is in close contact with the inner wall of the central box 11. By setting the first sealing ring 2215, it is used to seal between the rotating rod 2103 and the round block 2104, and the normal rotation of the rotating rod 2103 can be guaranteed. By setting the second sealing ring 2216, it is used to seal between the rotating rod 2103 and the central box 11 to avoid leakage of carrageenan waste liquid.

[0048] The specific implementation of this embodiment is as follows: after the work is completed, when the impurities are scraped off, a small amount of impurities will be stuck in the mesh. When the round block 2104 rotates, it will drive the suction plate 2201 to move in a circular motion. At this time, the external control switch is started to start the air pump 2207, so that negative pressure is generated in the central pipe 2205, the air guide pipe 2204, the rotating rod 2103, and the suction plate 2201, so that the gas is sucked in from the suction hole 2202. When impurities enter the interior of the fixed box 2206, the dust filter 2217 in the fixed box 2206 can filter the impurities to prevent the impurities from being sucked in. When the suction plate 2201 is used for circular movement, the moving block 2208 is moved upward, so that the moving block 2208 drives the telescopic rod 2210 to contract, and the spring 2211 is compressed. When the squeezing of the moving block 2208 is cancelled, the force deformation of the spring 2211 drives the moving block 2208 to move downward, so that the knocking block 2209 knocks the filter screen 2102, thereby achieving the effect of loosening the impurities in the mesh, thereby better cleaning the impurities in the mesh.

By setting up the infusion mechanism 3, the water level and pH value of the carrageenan waste liquid in the collection tank 11 can be detected by the water level sensor 303 and the pH sensor 302. When it is detected that the pH value of the carrageenan waste liquid is lower than the set numerical range, the controller 308 starts one of the water pumps 307 to transport the carrageenan waste liquid with a higher pH value to the collection tank 11. When the pH value of the carrageenan waste liquid is higher than the set numerical range, the other water pump 307 is started to transport the water in the water collection chamber 305 to the collection tank 11, thereby achieving the effect of adjusting the pH value of the carrageenan waste liquid.

[0051] Two feed pipes 309 are fixedly connected to the top of the liquid storage tank 304, and a pipe cover 310 is threadedly connected to the surface of the feed pipe 309. A control valve 311 is fixedly connected to one side of the liquid storage tank 304. There are two control valves 311. By setting the feed pipe 309, the pipe cover 310 and the control valve 311 for coordinated use, water can be added to the water collection chamber 305 through the feed pipe 309, and carrageenan waste liquid with a higher pH value can be added to the liquid collection chamber 306 through the feed pipe 309, thereby achieving the effect of replenishing water and carrageenan waste liquid. By rotating the pipe cover 310, the feed pipe 309 is sealed.

[0052] The specific implementation of this embodiment is as follows: the water level and pH value of the carrageenan waste liquid in the collection tank 11 can be detected by the water level sensor 303 and the pH sensor 302. When the pH value of the carrageenan waste liquid is detected to be lower than the set numerical range, the controller 308 starts one of the water pumps 307 to transport the solution with a higher pH value to the collection tank 11. When the pH value of the carrageenan waste liquid is higher than the set numerical range, the other water pump 307 is started to transport the solution with a lower pH value in the water collection chamber 305 to the collection tank 11, thereby achieving the effect of adjusting the pH value of the carrageenan waste liquid and adjusting the pH value of the carrageenan waste liquid to an appropriate range (e.g., 6.0~7.0) for subsequent processing.

[0053] A method for using a carrageenan production water recovery and treatment device comprises the following steps:

[0054] S1. The collected carrageenan waste liquid is transported to the top of the liquid guide housing 2108 through the liquid inlet pipe 12. The carrageenan waste liquid is guided to the top of the filter screen 2102 through the liquid guide housing 2108. The mesh size of the three upper filters 2102 gradually decreases from top to bottom. The mesh size of the bottom filter screen 2102 is consistent with the mesh size of the second-to-last filter screen 2102. The filter screen 2102 is used to filter out impurities. During the filtering process, the rotating rod 2103 is rotated to cause the scraper 2105 to scrape off impurities on the top of the filter screen 2102, so that the impurities move to the drop hole 2106 and are collected by the receiving housing 2114. Frequent manual cleaning of the filter screen 2102 is unnecessary.

[0055] S2. The water level and pH value of the carrageenan waste liquid in the collection tank 11 can be detected by the water level sensor 303 and the pH sensor 302. When the pH value of the carrageenan waste liquid is detected to be lower than the set value range, the controller 308 starts one of the water pumps 307 to transport the solution with a higher pH value to the collection tank 11. When the pH value of the carrageenan waste liquid is higher than the set value range, the other water pump 307 is started to transport the solution with a lower pH value in the water collection chamber 305 to the collection tank 11, thereby achieving the effect of adjusting the pH value of the carrageenan waste liquid to an appropriate range (e.g., 6.0-7.0) for subsequent treatment;

[0056] S3. After the work is completed, a small amount of impurities will be stuck in the mesh. When the round block 2104 rotates, it will drive the suction plate 2201 to move in a circle. At this time, the external control switch is started to start the air pump 2207, so that negative pressure is generated in the central pipe 2205, the air guide pipe 2204, the rotating rod 2103, and the suction plate 2201. Among them, there is a certain gap between the suction plate 2201 and the mesh, so that the gas is sucked in from the suction hole 2202. When impurities enter the interior of the fixed box 2206, the dust filter 2217 in the fixed box 2206 can filter the impurities to prevent the impurities from being sucked into the suction pump 2207. During adsorption, the knocking block 2209 will knock on the filter 2102 to loosen the impurities in the mesh, so that the impurities in the mesh can be cleaned.
