Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to sewage purification equipment and a process based on the production of thermoplastic elastomers. Background Art

[0002] Thermoplastic elastomers, also known as artificial rubber or synthetic rubber, are a type of elastomer that has the elasticity of rubber at room temperature and can be plasticized and molded at high temperatures. The cleaning and polymerization reactions in the production process of thermoplastic elastomers will generate a large amount of wastewater. The wastewater usually contains organic matter (such as residual monomers and additives), suspended solids (SS), oily substances, acidic and alkaline pollutants, etc. These wastewaters need to be treated in a standardized manner before they can be discharged.

[0003] Patent publication number CN116514251A discloses a wastewater treatment device and method for producing rubber accelerators, wherein the wastewater treatment device for producing rubber accelerators includes a barrel body, a treatment barrel is rotatably installed in the barrel body, a driving assembly for driving the treatment barrel to rotate is installed below the barrel body, a plurality of partitions are fixedly connected to the inner wall of the treatment barrel, the partitions are used to separate the treatment barrel into a plurality of water storage tanks, water outlets are respectively opened at the bottom end of the outer surface of the treatment barrel at positions corresponding to each water storage tank, a sealing assembly for automatically opening or closing the water outlet is provided at the water outlet, a filter is fixedly connected to the inner surface of the barrel body, and a cleaning assembly is provided on one side of the filter. The present invention can group the wastewater produced by rubber accelerators for treatment, so that each group of wastewater is subjected to stirring, mixing, flocculation, sedimentation and filtration processes in sequence, which is convenient to use and improves the use effect.

[0004] The existing technology has the following defects: During sewage treatment, chemicals need to be continuously added to the regulating tank to adjust the water quality. At present, the commonly used chemical mixing methods in sewage treatment plants include mechanical stirring. When the sewage flow fluctuates greatly and the treatment scale increases, it is easy to cause the chemical concentration in local areas to be too high or too low. The mixing process lacks targeted strengthening measures, and it is difficult for the chemical to fully react with the pollutants. The uneven mixing of the chemical directly leads to a decrease in the sewage treatment effect. At the same time, insufficient mixing will also cause ineffective consumption of chemicals, increase operating costs, and is not conducive to large-scale promotion.

[0005] When regulating water quality, in order to accurately control the amount of reagents added, it is necessary to extract sewage samples from the regulating tank for testing. However, due to the large scale of the regulating tank, the sewage reaction states in different areas are also uneven. Therefore, obtaining sewage samples from only one water area will lead to errors in the test results and affect the accuracy of the reagent addition. Summary of the Invention

When sampling, the sewage flows back into the receiving box, and the sample can be extracted from the connecting pipe, which makes it convenient to obtain the sample.

[0019] 3. By setting up a control component, when the liquid medicine is added, the sliding sleeve slides upward to control the rotation of the rotating shaft, and the rotating shaft drives the half-cylinder to rotate to open the outflow hole. This makes the control convenient and enables multiple half-cylinders to work synchronously.

When sampling, the sliding sleeve moves downward. After the sliding sleeve drops, the lower end of the flow hole is blocked. In this way, the sewage can be stably stored after entering the receiving box, making the sampling process more convenient.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] Example 1, reference Figure 1-15 , which is the first embodiment of the present invention, provides a sewage purification treatment equipment based on thermoplastic elastomer production, including a regulating tank 1, a bridge 2 arranged at the top of the regulating tank 1, a stirring motor 3 arranged at the top of the bridge 2, a main shaft 4 arranged at the lower end of the stirring motor 3, and a stirring shaft 5 arranged on the outside of the main shaft 4.

[0025] Specifically, the regulating tank 1 is filled with sewage, the bridge 2 is clamped on the top of the regulating tank 1, the stirring motor 3 is fixed to the bridge 2 by bolts, the main shaft 4 is sleeved on the outside of the output shaft of the stirring motor 3 and fixed by bolts, the stirring shaft 5 is welded to the outside of the main shaft 4 and connected to the main shaft 4, and the stirring shaft 5 is divided into three groups of upper, middle and lower, and each group is provided with three; the outflow hole 61 and the inflow hole 62 are distributed in a linear array along the central axis of the stirring shaft 5, and the outflow hole 61 and the inflow hole 62 are symmetrically distributed based on the central axis of the stirring shaft 5, and the central axes of the outflow hole 61 and the inflow hole 62 are both horizontally perpendicular to the central axis of the stirring shaft 5, and the inflow hole 62 is located on the stirring shaft 5 is in the same direction as the rotation direction of the stirring shaft 5. The opening diameter of the inflow hole 62 is larger than the outflow hole 61, so that sewage can flow in more easily. The half cylinder 64 is fixedly connected to the rotating cylinder 63. The half cylinder 64 is specifically a half cylindrical hollow cylinder. The half cylinder 64 closes the outflow hole 61 or the inflow hole 62. The outer wall of the rotating shaft 65 is in contact with the inner wall of the main shaft 4. The outer side of the rotating shaft 65 is provided with an inlet corresponding to the circulation hole 67. The communicating hole 66 is connected to the rotating cylinder 63. Four sets of sealing rings are arranged between the rotating shaft 65 and the main shaft 4, of which three sets of sealing rings are distributed on the upper and lower sides of the communicating hole 66, and one set of sealing rings is located below the circulation hole 67.

[0026] The purification agents specifically include an inorganic coagulant, an oxidant and a pH regulator. The inorganic coagulant may be polyaluminum chloride or polyferric sulfate, the oxidant specifically includes hydrogen peroxide plus ferrous salt, and the pH regulator may be sodium hydroxide or hydrochloric acid.

[0027] By setting up the diversion component 6, when adding the medicine, the half cylinder 64 is rotated to open the outflow hole 61, and the main shaft 4 drives the stirring shaft 5 to rotate and stir the sewage, and the medicine flows out from the outflow hole 61. In this way, the medicine flows into the sewage from the upper, middle and lower areas, and the outflow point of the medicine moves with the rotation of the stirring shaft 5, which can make it mixed more evenly and allow the sewage to react fully. When sampling, the half cylinder 64 is rotated to open the inflow hole 62, and the inflow hole 62 moves towards the sewage. The sewage in the upper, middle and lower areas flows into the main shaft 4 and is collected. In this way, mixed samples of multiple areas in the regulating tank 1 can be obtained, making the detection results more accurate, thereby reducing the cost of sewage treatment, improving efficiency, and being more suitable for large-scale promotion.

[0028] Specifically, the bottom of the bridge 2 is fixedly installed with a receiving box 8, and the main shaft 4 passes through the receiving box 8 along the central axis of the receiving box 8. The receiving box 8 is wrapped around the outside of the circulation hole 67. The receiving box 8 is fixed to the bridge 2 by bolts, and the bottom wall of the receiving box 8 is flush with the bottom wall of the circulation hole 67; a connecting pipe 81 is fixedly connected to the outside of the receiving box 8, and the connecting pipe 81 is "L-shaped", and the top opening extends to the top of the bridge 2.

[0029] By setting up the receiving box 8, when the medicine is added, the medicine can be put into the receiving box 8 from the connecting pipe 81, so that the medicine can enter the rotating shaft 65 from the high-speed rotating flow hole 67 and the inlet, so that the addition of the medicine is continuous and stable. When sampling, the sewage flows back into the receiving box 8, and the sample can be extracted from the connecting pipe 81, which makes it convenient to obtain the sample.

[0030] The control assembly 7 specifically includes a main slide groove 71 opened on the outside of the rotating shaft 65, a sliding sleeve 72 arranged on the outside of the main shaft 4, a main sliding rod 73 arranged inside the sliding sleeve 72, a secondary slide groove 74 opened on the outside of the rotating shaft 65, and a secondary sliding rod 75 arranged on one end of the rotating cylinder 63 close to the rotating shaft 65.

[0031] When the cam 72 is in the closed position, the locking cam 73 is in the closed position, and the stop 72 is in the closed position, the stop 73 is in the closed position, and the cam 73 is in the closed position, the stop 73 is in the closed position, and the stop 73 is in the closed position.

[0032] By setting up the control component 7, when the medicine liquid is added, the sliding sleeve 72 slides upward to control the rotation of the rotating shaft 65, and the rotating shaft 65 drives the half cylinder 64 to rotate to open the outflow hole 61. This makes the control convenient, so that multiple half cylinders 64 can work synchronously, and after the sliding sleeve 72 is lifted, the lower end of the flow hole 67 is opened, so that the medicine liquid in the receiving box 8 can completely flow into the rotating shaft 65, avoiding the occurrence of medicine liquid residue. When used, the sliding sleeve 72 moves downward. After the sliding sleeve 72 drops, the lower end of the flow hole 67 is blocked, so that the sewage can be stably stored after entering the receiving box 8, making the sampling process more convenient.

[0033] Specifically, an outer opening communicating with the inner space of the stirring shaft 5 is formed at one end of the stirring shaft 5 away from the main shaft 4, and a tail cap 51 is also threadedly connected to this end, which closes the outer opening. In this way, the installation of the rotating cylinder 63 and the half cylinder 64 can be facilitated by disassembling and assembling the tail cap 51.

[0034] Specifically, the interior of the rotating shaft 65 is fixedly connected to the inner shaft 68, and the rotating shaft 65 and the inner shaft 68 are fixed by a connecting beam. A flow cavity is provided between the inner wall of the rotating shaft 65 and the outer wall of the inner shaft 68. The space of the flow cavity is relatively narrow, so that the liquid medicine therein can flow relatively evenly into the upper, middle and lower parts of the stirring shaft 5, which is also convenient for lifting the sewage when pumping the sewage.

[0035] Specifically, fifteen unit areas are equidistantly arranged on the outer circumference of the rotating shaft 65, and the communicating holes 66 are correspondingly distributed in the fifteen unit areas. The communicating holes 66 are divided into three groups corresponding to the stirring shaft 5, namely, six in the upper part, nine in the middle part, and twelve in the lower part. Initially, the rotating cylinders 63 in the upper, middle and lower parts are all docked with the communicating holes 66; when the rotating shaft 65 rotates one unit, the upper rotating cylinder 63 no longer docks with the communicating holes 66, and the rotating cylinders 63 in the middle and lower parts dock with the communicating holes 66; when the rotating shaft 65 rotates two units, the upper and middle rotating cylinders 63 no longer dock with the communicating holes 66, and the lower two rotating cylinders 63 dock with the communicating holes 66; when the rotating shaft 65 rotates three units, the upper rotating cylinder 63 The three rotating cylinders 63 in the middle and lower positions are no longer connected to the connecting hole 66; the rotating shaft 65 rotates four units, and the three rotating cylinders 63 in the upper, middle and lower positions are all connected to the connecting hole 66. The length of the auxiliary sliding rod 75 covers five units, and the lower section occupies four units. A spiral blade is installed on the inner wall of the rotating shaft 65, and the inner side of the spiral blade fits into the surface of the inner shaft 68, which can be used to lift sewage. When setting the spiral blade, it is necessary to avoid the connecting hole 66 so that there is no overlapping part between the two. A rotating bearing is set between the top of the inner shaft 68 and the rotating shaft 65. The bottom end of the inner shaft 68 passes through the rotating shaft 65 and the main shaft 4. The inner shaft 68 is inserted into the bottom wall of the regulating tank 1, and the height of the receiving box 8 from the sewage liquid level is not more than fifty centimeters.

[0036] By providing the communicating holes 66 arranged in a standardized manner, the deflecting rotating shaft 65 can be used to control the delivery of the liquid medicine to a designated area when discharging the liquid medicine, so that targeted adjustments can be made according to the on-site conditions.

[0037] The control assembly 7 further includes an adjustment disk 76 arranged on the outside of the sliding sleeve 72 , three guide rods 77 arranged on the inner bottom wall of the receiving box 8 and distributed in a circular array, and a regulator 78 arranged on the top of one of the guide rods 77 .

[0038] Specifically, the adjusting disk 76 is rotatably connected to the outer side of the sliding sleeve 72. A through hole and a shock-absorbing hole are provided on the surface of the adjusting disk 76. A guide rod 77 passes through the through hole. An external interface is provided on the side of the top of the receiving box 8 away from the connecting pipe 81. The adjuster 78 is located above the guide rod 77 at the external interface, and a thread for controlling the up and down movement of the adjusting disk 76 is provided on the outer side of the guide rod 77 here. The adjuster 78 can be externally connected to an adjusting motor or an external rotating handle to control the rotation of the adjuster 78. The adjusting disk 76 and the sliding sleeve 72 are separated in half and fixed by bolts.

[0039] By providing the adjustment disk 76 , it is convenient to control the movement of the sliding sleeve 72 , and the guide rod 77 can guide the adjustment disk 76 to make it move smoothly and apply a uniform thrust to the sliding sleeve 72 .

[0040] The working principle of the sewage purification treatment equipment produced based on thermoplastic elastomer of the present invention is as follows: The hopper 74 is then driven by the piston rod 76 to move upwards, and the piston rod 77 is rotated to move upwards, so that the piston rod 76 moves upwards, and the piston rod 76 is rotated to move upwards on the outside of the hopper 4. The piston rod 76 is driven upwards, and the piston rod 76 is driven upwards, so that the piston rod 76 moves upwards, so that the piston rod 76 moves upwards, and the piston rod 76 is rotated to move upwards on the outside of the hopper 4. The piston rod 76 is driven upwards, so that the piston rod 76 moves upwards, so that the piston rod 76 moves upwards, and the piston rod 76 is rotated to move upwards on the outside of the hopper 4. The piston rod 76 is driven upwards, so that the piston rod 76 moves upwards, and the piston rod 76 is rotated to move upwards on the outside of the hopper 4. The piston rod 76 is driven upwards, so that the piston rod 76 moves upwards, and the piston rod 76 is rotated to move upwards to the end of the lower section of the piston rod 76. The piston rod 76 is driven upwards, so that the piston rod 76 is rotated

[0041] The sliding sleeve 72 is controlled to move downward a certain distance, and the main sliding rod 73 is used to rotate the rotating shaft 65 one unit. At this time, the upper rotating cylinder 63 is no longer connected to the connecting hole 66, and the middle and lower rotating cylinders 63 are connected to the connecting hole 66. In this way, the upper outflow hole 61 no longer discharges liquid medicine, while the middle and lower outflow holes 61 continue to discharge liquid medicine, and the open area of the lower half of the circulation hole 67 is also reduced. Later, you can choose to rotate two units or three units.

[0042] When sampling, the rotating shaft 65 is controlled to rotate four units, and the auxiliary sliding rod 75 enters the upper section from the lower section of the auxiliary chute 74 through the transition section. The auxiliary sliding rod 75 moves from the bottom of the central axis of the rotating cylinder 63 to the top, causing the half cylinder 64 to rotate one hundred and eighty degrees. The half cylinder 64 closes the outflow hole 61 and opens the inflow hole 62. When the rotation is accelerated, the inflow hole 62 moves against the sewage, and the sewage and the stirring shaft 5 move relative to each other. The sewage forms pressure on the space inside the stirring shaft 5, and the sewage level in the rotating shaft 65 rises. At the same time, the rotating spiral blades will also generate thrust on the sewage, causing the sewage to flow into the receiving box 8, so that samples can be extracted from the connecting pipe 81.

[0043] Example 2, reference Figure 1-15 , as a second embodiment of the present invention, provides: a wastewater purification process based on the production of thermoplastic elastomer, comprising the following steps: Pretreatment: Large particles of impurities are intercepted by mechanical screens, inorganic particles are removed in grit chambers to prevent clogging of subsequent equipment, and floating oil is separated using gravity oil separators. Water quality regulation: balance the water quality and quantity of sewage in regulating tank 1, add chemicals, equip with a stirring device for stirring, and adjust the pH to neutral.

[0044] Biochemical treatment: Use activated sludge method (traditional aeration tank, SBR) or biofilm method (contact oxidation method, aerated biological filter) to degrade organic matter through microbial metabolism and reduce COD and BOD.

[0045] Coagulation, sedimentation and filtration: Add PAC, PAM and other coagulants to flocculate gel particles and organic matter, and then remove suspended matter and some organic matter through quartz sand filter, activated carbon filter or ultrafiltration.

[0046] Advanced oxidation: Use ozone oxidation, Fenton oxidation or photocatalytic oxidation to decompose refractory organic matter (such as benzene series and polyurethane intermediates).

[0047] Sludge treatment: Reduce the moisture content of sludge by gravity concentration or centrifugal concentration, and further dehydrate it to form a sludge cake using a plate and frame filter press, belt filter press or centrifugal dehydrator.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
