Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a square protein separator. Background Art

[0002] Protein skimmers play an important role in sewage treatment. They can effectively remove organic matter in sewage, especially proteins, sugars, lipid colloids and other organic matter, which helps to improve sewage treatment efficiency, improve effluent water quality, and provide a new way for resource recycling.

[0003] The utility model with announcement number CN203006978U discloses a compression bin of a protein separator, which relates to auxiliary equipment of the protein separator; it comprises a bin body of the compression bin arranged at the bottom of the reaction bin of the protein separator, the bin body having an inner cavity communicated with the reaction bin of the protein separator, a water inlet being arranged on the bin body, and the water inlet being connected to the water outlet of a water pump of the protein separator, a sieve plate which divides the inner cavity into two parts being arranged on the bin body above the water inlet, and a plurality of water passing holes being arranged on the sieve plate; the bubbles in irregular motion are formed into bubbles which rise stably, and the surface of the bubbles is stable, thereby improving the effective utilization rate and processing capacity of the protein separator, and the processing capacity of the protein separator is better and more energy-saving.

DETAILED DESCRIPTION

[0058] The following will be combined with the specific implementation of the present invention to clearly and completely describe the technical solution in the present invention. Obviously, the described implementation is only a part of the implementation of the present invention, not all of the implementation. Based on the implementation of the present invention, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] like Figure 1-14 As shown, a square protein skimmer of the present invention comprises a body 1, a water vapor treatment box 2, a blocking mechanism 3, a water pump 4, a guide plate 5, a dividing plate 6, a receiving plate 7, a cover plate 8 and a receiving box 9.

[0060] Among them, the body 1 is used to carry other components. The body 1 includes a water tank 11, a water inlet pipe 12, a water outlet pipe 13 and an air inlet pipe 14. The water inlet pipe 12 and the water outlet pipe 13 are both penetrated and fixed on the water tank 11; the air inlet pipe 14 is penetrated and fixed on the water inlet pipe 12; the water pump 4 is fixedly arranged in the water tank 11, and its input end is sealed and connected with the water inlet pipe 12, and its output end penetrates and is sealed and fixed on the bottom side of the water vapor treatment box 2; when the water pump 4 is started, water enters the water tank 11 through the water inlet pipe 12, and the outside air enters the water inlet pipe 12 through the air inlet pipe 14, and mixes with the water to form a water vapor mixture, so as to separate the protein in the water by using bubbles.

[0061] The water vapor treatment box 2 is used to control the size and flow direction of the bubbles in the water vapor mixture. A plurality of water holes 201 are provided on the top side of the water vapor treatment box 2. When the water vapor mixture enters the water vapor treatment box 2, the water holes 201 can be used to refine the bubbles in the water vapor mixture, so that the particle size of the bubbles in the water vapor mixture is smaller than the inner diameter of the water holes 201, thereby increasing the contact area between the bubbles and the water body and improving the water purification effect of the protein skimmer; at the same time, the water vapor mixture can flow stably upward along the direction of the water holes 201, which can avoid the problem of uneven distribution of bubbles and ensure the purification efficiency of sewage.

[0062] When the air content in the water vapor mixture is relatively large, the air in the water vapor mixture will be presented in the form of linear air flow rather than bubble shape. The linear air flow has a smaller specific surface area, a smaller contact area with the water body, and the air gathers together, resulting in uneven distribution of water vapor, which affects the purification effect of the protein skimmer. For this reason, a blocking mechanism 3 is provided, and the blocking mechanism 3 intermittently blocks the water hole 201, so that the water hole 201 is intermittently opened and closed. Even if the air content in the water vapor mixture is relatively large, the air flow through the water hole 201 can only be in a small segment, and no long linear air flow will be formed, thereby increasing the contact area between the air and the water body, allowing the air and water to mix more evenly, thereby improving the water purification effect of the protein skimmer.

[0063] like Figure 4 As shown, the blocking mechanism 3 includes a rotating shaft 31, a plurality of spiral blades 32 and a baffle 33. The rotating shaft 31 passes through and is rotatably arranged on the top side of the water vapor treatment box 2; the spiral blades 32 are fixedly arranged on the rotating shaft 31, and when the water vapor mixture flows through the water vapor treatment box 2, the cooperation between the spiral blades 32 and the spiral blades 32 will drive the spiral blades 32 to rotate; the baffle 33 is fixedly arranged on the rotating shaft 31 and blocks the water through hole 201. A plurality of connecting holes 301 are opened in the baffle 33, and the number of connecting holes 301 is less than the number of water through holes 201. When the rotating shaft 31 rotates, at least one connecting hole 301 is connected to at least one water through hole 201; preferably, the baffle 33 is arranged on the top side of the water vapor treatment box 2, and the spiral blades 32 are arranged inside the water vapor treatment box 2, as shown in FIG. Figure 8 As shown, when the water-gas mixture flows through the water-gas treatment box 2, the rotating shaft 31 can drive the baffle 33 to rotate, and then the baffle 33 and the water-gas treatment box 2 cooperate to intermittently block the water hole 201, thereby avoiding the generation of long linear air flow.

[0064] like Figure 6-Figure 7 As shown, the plurality of water holes 201 and the plurality of connecting holes 301 are arranged in a circular array around the center line of the rotating shaft 31, as shown in FIG. Figure 7 As shown, the solid circle line is the connecting hole 301, and the dotted circle line is the water hole 201. It is preferred that the number of the connecting holes 301 is half of the number of the water holes 201, and the interval between two adjacent connecting holes 301 is twice the interval between two adjacent water holes 201. When the connecting holes 301 are all connected to one water hole 201, the remaining half of the water holes 201 are blocked by the baffle 33. When the rotating shaft 31 rotates, multiple water holes 201 can be blocked in turn, thereby achieving the technical effect of intermittently blocking the water holes 201 by the blocking mechanism 3.

[0065] The inner diameter of the connecting hole 301 is larger than the interval between two adjacent water holes 201, but not larger than the inner diameter of the water holes 201. It is preferred that the inner diameter of the connecting hole 301 is equal to the inner diameter of the water holes 201; Figure 6As shown, when the connecting hole 301 rotates to the middle of two adjacent water holes 201, the connecting hole 301 can still be partially connected to the two water holes 201, thereby avoiding the situation where all the water holes 201 are blocked, allowing the water-gas mixture in the water tank 11 to flow continuously, thereby driving the spiral blades 32 and the rotating shaft 31 to rotate continuously, driving the baffle 33 to block the water holes 201 in turn.

[0066] When the baffle 33 abuts against the water-gas treatment box 2 and is rotatably connected thereto, part of the water holes 201 are blocked, resulting in a relatively small conveying cross section of the water-gas mixture, which is not conducive to increasing the displacement of the protein skimmer; Figure 8 As shown, in order to solve this problem, the rotating shaft 31 is rotatably and slidably connected to the water vapor treatment box 2, and an elastic member 34 is arranged in the sealing mechanism 3. The elastic member 34 is fixedly arranged on the water vapor treatment box 2 and abuts against the rotating shaft 31. In a natural state, the elastic member 34 makes the baffle 33 abut against the top side of the water vapor treatment box 2. When the air content in the water vapor mixture is small, the output pressure of the water pump 4 can be increased, thereby increasing the pressure of the water vapor mixture, driving the rotating shaft 31 and the water vapor treatment box 2 to slide, separating the baffle 33 from the water vapor treatment box 2, and allowing all the water holes 201 to be unblocked by the baffle 33, so that the water vapor mixture can flow through each water hole 201.

[0067] As a preferred embodiment, the elastic member 34 includes a sleeve 341, a slide rod 342, a supporting head 343 and a spring 344. The sleeve 341 is fixedly arranged on the water vapor treatment box 2 and has a slide groove 302 therein; the slide rod 342 is slidably arranged in the slide groove 302; the supporting head 343 is fixedly arranged on the slide rod 342 and is supported by the rotating shaft 31; the spring 344 is slidably arranged in the slide groove 302 and is supported by one end of the slide rod 342 away from the supporting head 343; the spring 344 is used to The elastic support of 344 on the sliding rod 342 makes the supporting head 343 elastically support the rotating shaft 31. When the pressure of the water-gas mixture is less than the pressure of the spring 344, the baffle 33 is in contact with the water-gas treatment box 2, so that the baffle 33 blocks part of the water holes 201. When the pressure of the water-gas mixture is greater than the pressure of the spring 344, the baffle 33 is separated from the water-gas treatment box 2, so that all the water holes 201 are not blocked, thereby ensuring the displacement of the protein skimmer.

[0068] like Fig. 9As shown, there are multiple slide grooves 302, slide rods 342 and springs 344, and the multiple slide grooves 302, slide rods 342 and springs 344 are arranged in a circular array around the center line of the rotating shaft 31 and correspond one to one. The lengths of the multiple slide rods 342 are the same, and the lengths of the multiple springs 344 are different. When the pressure on the abutting head 343 is small, the slide rod 342 abuts against one spring 344. As the pressure of the water-gas mixture increases, the spring 344 contracts, and the slide rod 342 abuts against two springs 344 or even three springs 344. As the number of springs 344 abutted by the slide rod 342 increases, the elastic force of the springs 344 on the slide rod 342 increases exponentially, thereby increasing the range of water-gas mixture pressure borne by the elastic member 34, so that the elastic member 34 can adapt to water-gas mixtures with different pressures; at the same time, relative to the arrangement of one spring 344, three springs 344 of different lengths can also reduce the occupied space of the elastic member 34, thereby improving the space utilization rate of the protein skimmer.

[0069] In some embodiments, multiple groups of water holes 201 are provided, and multiple water holes 201 are provided in each group of water holes 201. The multiple water holes 201 in the same group are arranged in a circular array around the center line of the water vapor treatment box 2. The multiple groups of water holes 201 are concentric and equidistant. The inner diameters of the multiple water holes 201 in the same group are equal, and the inner diameters of the multiple water holes 201 in different groups are different, and the inner diameter of the water hole 201 is inversely proportional to the distance between it and the center line of the water vapor treatment box 2; Figure 2 As shown, a plurality of water holes 201 are radially distributed, and the inner diameter of the water holes 201 gradually decreases in the direction from the middle of the water vapor treatment box 2 to the outer edge of the water vapor treatment box 2. When purifying the water body, the inner diameter of the bubbles in the middle position of the water tank 11 is relatively large, and the disturbance effect on the water body is relatively good, so that the water body at the edge position of the water tank 11 can flow toward the middle position of the water tank 11, thereby promoting the mixing of the bubbles and the water body, which is beneficial to improving the purification effect of the water body.

[0070] The guide plate 5 is used to guide the water-gas mixture in the water tank 11. The guide plate 5 includes a first guide portion 51 and a second guide portion 52. One end of the first guide portion 51 and one end of the second guide portion 52 are integrally formed and continuously arranged. The first guide portion 51 and the second guide portion 52 are both sealed and fixed in the water tank 11 and are located above the water-gas treatment box 2. The end of the second guide portion 52 away from the first guide portion 51 is spaced apart from the inner wall of the water tank 11. By guiding the water-gas mixture with the first guide portion 51 and the second guide portion 52, the water-gas mixture can be made to flow toward one of the side walls in the water tank 11, which is beneficial for centralized treatment of bubbles and foam mixed with protein. The end of the second guide portion 52 close to the first guide portion 51 is located below the end of the second guide portion 52 away from the first guide portion 51, and is located above the end of the first guide portion 51 away from the second guide portion 52. The inclination angle of the second guide portion 52 to the horizontal plane is greater than the inclination angle of the first guide portion 51 to the horizontal plane. Figure 1 As shown, the first guide portion 51 is arranged in a relatively gentle manner, allowing the bubbles to slowly pass through the water body, thereby fully purifying the water body; the second guide portion 52 is arranged in a relatively steep manner, which allows the bubbles to be quickly concentrated together, thereby helping to improve the purification efficiency of the protein skimmer and avoid secondary dispersion of protein into the water body.

[0071] The dividing plate 6 is used for secondary refinement of the bubbles. The dividing plate 6 is fixedly arranged between the first guide part 51 and the water tank 11, and is located on the side of the first guide part 51 close to the water vapor treatment box 2. The dividing plate 6 is parallel to the horizontal plane, and a plurality of dividing holes 601 are opened inside it. In the process of full overlap between the bubbles and the water body, the plurality of dividing holes 601 are used to decompose the bubbles with relatively large particle size into a plurality of tiny bubbles, which is beneficial to improving the purification effect of the protein skimmer.

[0072] like Fig.11 As shown, the dividing hole 601 includes two end holes 6011 and a slit 6012. The end hole 6011 is provided on the dividing plate 6. The two end holes 6011 are arranged at intervals, and the inner diameters of the two end holes 6011 are equal. The spacing between two adjacent end holes 6011 in different dividing holes 601 is equal to the spacing between two end holes 6011 in the same dividing hole 601, that is, a plurality of end holes 6011 are arranged in a matrix manner; the slit 6012 is provided on the dividing plate 6, and its two ends are respectively connected to the two end holes 6011, and the width of the slit 6012 is smaller than the inner diameter of the end hole 6011. When a relatively large bubble passes through the dividing hole 601, the bubble can be squeezed into an I-shape. In the process of the bubble rising, the middle position of the I-shaped bubble will be disconnected due to the influence of water resistance, thereby decomposing the I-shaped bubble into two spherical bubbles. Compared with the existing circular dividing hole 601, the dividing hole 601 has a better bubble segmentation effect.

[0073] It is preferred that the length direction of the slit 6012 is perpendicular to the length direction of the guide plate 5. When the bubbles are guided by the guide plate 5, they can still move evenly to the two end holes 6011 in the dividing hole 601, thereby avoiding the problem of bubbles in the two end holes 6011 in the same dividing hole 601 being larger and smaller.

[0074] At the same time, since multiple end holes 6011 are arranged equidistantly, the dividing hole 601 can be cleaned using an equidistantly arranged conical needle plate. The specific operation is: first insert the conical needle into one of the end holes 6011, clean one of the end holes 6011, then slide the needle tip of the conical needle through the slit 6012 into the other end hole 6011, and finally insert the conical needle completely into the other end hole 6011, thereby cleaning the entire dividing hole 601. Compared with the circular dividing hole 601, the inner diameter of the dividing hole 601 is larger, which makes it easier for dirt to be dispersed, thereby making the cleaning of the dividing hole 601 more thorough.

[0075] The receiving plate 7 is used to collect the floating foam or bubbles on the top of the water tank 11. The receiving plate 7 is sealed and fixed between the second guide portion 52 and the water tank 11, and is respectively arranged on both sides of the guide plate 5 with the dividing plate 6. The top side of the receiving plate 7 is a structure with a middle bottom and a high edge, and a stepped hole 701 is arranged in the middle of the receiving plate 7. The top side of the water tank 11 is provided with an opening 101, and the cover plate 8 is detachably fixed in the opening 101; the receiving box 9 is fixedly arranged on the cover plate 8 and is snap-fitted with the stepped hole 701. A receiving hole 901 is opened on the peripheral side of the receiving box 9, and the bottom side of the receiving hole 901 is flush with the top side of the receiving plate 7; after the bubbles and floating foam are guided by the guide plate 5 to move to the top side of the receiving plate 7, they will gather toward the middle position of the receiving plate 7, and then enter the receiving box 9 through the receiving hole 901 for storage; in actual application, the receiving box 9 can be disassembled by disassembling the cover plate 8, so as to facilitate the cleaning of the receiving box 9.

[0076] The working principle of a square protein skimmer of the present invention is as follows:

[0077] After starting the water pump 4, the external water and air flow into the water tank 11 through the water inlet pipe 12 and the air inlet pipe 14 respectively, and form a water-gas mixture. The water-gas mixture first flows into the water-gas treatment box 2. The water holes 201 and the connecting holes 301 cooperate with each other and the baffle 33 blocks the water holes 201, so that the bubbles can fully and evenly merge with the water, thereby purifying the water. Subsequently, the water-gas mixture continues to move upward under the guidance of the guide plate 5, and the bubbles inside it continue to be subdivided through the dividing plate 6, so as to fully merge with the water, and fully purify the water. The bubbles attached with organic matter continue to rise and move, and move through the receiving plate 7 and the receiving hole 901 and are stored in the receiving box 9 for centralized treatment, and the purified water is discharged from the body 1 through the water outlet pipe 13. When the air content in the water-gas mixture is small and the air is not in a linear shape, the output pressure of the water pump 4 can be increased to separate the baffle 33 from the water-gas treatment box 2, thereby improving the purification efficiency of the protein skimmer.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
