Description

Technical Field

[0002] Carrageenan is a natural polysaccharide hydrophilic glue 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] The existing carrageenan production water recovery and treatment devices, when treating carrageenan waste water, mostly use a filter to filter out impurities therein, but the filter is easily clogged by impurities, resulting in the filter cannot be used for a long time. Although the prior art uses a scraping method to clean impurities, it is difficult to scrape away some impurities slightly larger than the mesh, which affects the efficiency of carrageenan waste water treatment.

[0016] A method for using a carrageenan production water recovery and treatment device comprises the following steps: S1. The collected carrageenan waste liquid is transported to the top of the liquid guide shell through the liquid inlet pipe, and the carrageenan waste liquid is guided to the top of the filter screen through the liquid guide shell. The meshes of the upper three of the four filter screens gradually become smaller from top to bottom, and the meshes of the bottom filter screen are consistent with the meshes of the second to last filter screen. The filter screen is used to filter impurities. During the filtering process, the rotating rod is rotated so that the scraper scrapes the impurities on the top of the filter screen, so that the impurities move to the drop hole, and the impurities are collected by the receiving shell, and there is no need to manually clean the filter screen frequently; S2. The water level and pH value of the carrageenan waste liquid in the concentration box 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 concentration box. 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 concentration 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; 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 started 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.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 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 guide the carrageenan waste liquid to the top of the filter screen through the liquid guide shell. The meshes of the upper three of the four filter screens gradually become smaller from top to bottom, and the meshes of the lowermost filter screen are consistent with the meshes of the second to last filter screen. The filter screen is used to filter impurities. During the filtering process, the rotating rod is rotated so that the scraper scrapes the impurities on the top of the filter screen, moves the impurities to the drop hole, and collects the impurities through the receiving shell, without the need for frequent manual cleaning of the filter screen.

[0018] 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 vacuum 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 vacuum pump. When adsorption is performed, 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.

[0019] 3. The present invention can detect the water level and pH value of the carrageenan waste liquid in the concentration box by setting an infusion mechanism, through a water level sensor and a pH sensor. When it is detected that the pH value of the carrageenan waste liquid is 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 concentration 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 concentration 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.

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 guiding 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 guiding shell 2108. The mesh size of the upper three of the four filter screens 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 impurities. During the filtering process, the rotating rod 2103 is rotated so that the scraper 2105 scrapes off the impurities on the top of the filter screen 2102, so that the impurities move to the drop hole 2106 for discharge.

[0025] One end of the rotating rod 2103 passes through the bottom of the central box 11 and is fixedly connected to a transmission shaft 2110. The two transmission shafts 2110 are connected through a belt 2111. A connecting rod 2112 is fixedly connected to the bottom of the central box 11. One end of the connecting rod 2112 is fixedly connected to a motor 2113. The output end of the motor 2113 is fixedly connected to the bottom of one of the transmission shafts 2110. By setting the motor 2113, the connecting rod 2112 and the transmission shaft 2110 for coordinated use, the motor 2113 is started by using an external control switch, so that the motor 2113 drives the transmission shaft 2110 to rotate, so that the belt 2111 drives the other transmission shaft 2110 to rotate, thereby achieving the effect of driving the two rotating rods 2103 to rotate at the same time, wherein the rotation speed of the rotating rod 2103 is slower, thereby reducing the carrageenan waste liquid falling into the inner cavity of the drop hole 2106.

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.

[0027] 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.

[0029] 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 the bottom of the absorption plate 2201 is provided with an absorption hole 2202, and the number of the absorption holes 2202 is several. 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, 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 outer shell 1, one end of the centralizing pipe 2205 is fixedly connected to the fixed box 2206, 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.

By setting the collecting unit 22, 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 circle.

When impurities enter the interior of the fixed box 2206, the dust filter net 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, wherein the dust filter net 2217 is installed by bolts, and the dust filter net 2217 can be replaced or cleaned.

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 impurities in the mesh.

[0031] A groove 2212 is 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 an 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.

[0032] 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, the number of the second sealing rings 2216 is several, the surface of the second sealing ring 2216 is in close contact with the inner wall of the central box 11, and the first sealing ring 2215 is provided to seal between the rotating rod 2103 and the round block 2104, and the normal rotation of the rotating rod 2103 can be ensured, and the second sealing ring 2216 is provided to seal between the rotating rod 2103 and the central box 11 to avoid leakage of carrageenan waste liquid.

[0033] 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 circle. At this time, the external control switch is started to start the vacuum 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 the 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. The filter screen 2102 is then cleaned by the knocking block 2209, thereby loosening the impurities in the mesh.

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 use together, water can be added to the water collecting chamber 305 through the feed pipe 309, and carrageenan waste liquid with a higher pH value can be added to the liquid collecting 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 can be sealed.

[0037] The specific implementation of this embodiment is as follows: the water level and pH value of the carrageenan waste liquid in the collection box 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 solution with a higher pH value to the collection box 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 box 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 (such as 6.0~7.0) for subsequent processing.

[0038] A method for using a carrageenan production water recovery and treatment device comprises the following steps: S1. 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 meshes of the three upper ones of the four filter screens 2102 gradually become smaller from top to bottom, and the meshes of the bottom filter screen 2102 are consistent with the meshes of the second-to-last filter screen 2102. The filter screen 2102 is used to filter impurities. During the filtering process, the rotating rod 2103 is rotated so that the scraper 2105 scrapes off the impurities on the top of the filter screen 2102, so that the impurities move to the drop hole 2106, and the impurities are collected through the material receiving shell 2114, and there is no need to manually clean the filter screen 2102 frequently; S2. The water level and pH value of the carrageenan waste liquid in the central 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 central 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 central 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 (such as 6.0-7.0) for subsequent treatment; 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 vacuum 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 vacuum pump 2207. During the 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.
