Description

Technical Field

[0001] The invention relates to the technical field of multi-stage sewage treatment, in particular to washing sewage pretreatment equipment for rubber roller production. Background Art

[0002] In the production process of rubber rollers, residual particles of rubber raw materials, rubber crumbs and other solid impurities will enter the washing sewage. These rubber particles and other suspended matter will make the sewage turbid and affect the water quality. In the production process, there are lubrication processes or equipment maintenance using grease, which will mix into the washing sewage to form oil film or oil droplets. Therefore, the washing sewage needs to be treated in multiple steps and at multiple levels. First, the larger rubber particles, crumbs and other suspended matter in the sewage are removed through the screen to prevent these large particles from entering the subsequent treatment equipment. Then, the inorganic sand and heavier solid impurities in the sewage are precipitated. Finally, the grease in the sewage is removed through the grease trap to prevent the grease from entering the subsequent treatment unit and affecting the treatment effect. Although the sewage has been treated by the screen and the sand settling tank before entering the grease trap, a small amount of rubber particles and other solid impurities may still enter the grease trap. These solid impurities will absorb the grease or form precipitation with the grease, causing the grease to be unable to float normally. At the same time, it will also affect the normal operation of the grease trap, such as blocking the oil outlet or the oil outlet pipeline. Summary of the invention

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example 1

[0038] Reference Figure 1-Figure 7 , which is the first embodiment of the present invention, and this embodiment provides a washing wastewater pretreatment device for rubber roller production. The washing wastewater pretreatment device for rubber roller production includes a grease trap 101, and a water inlet pipe 102 and a water outlet pipe 103 are respectively arranged on both sides of the grease trap 101. A filter screen 104 is fixed in the water inlet pipe 102.

[0039] After the washing wastewater is discharged, it is firstly passed through a screen to remove the larger rubber particles, debris and other suspended solids in the wastewater to prevent these large particles from entering the subsequent treatment equipment and causing equipment blockage. After passing through the screen, the wastewater flows into the grit chamber, the main purpose of which is to precipitate the inorganic sand particles and heavier solid impurities in the wastewater. These impurities settle to the bottom of the tank by gravity, and the wastewater that has undergone preliminary sand removal continues to flow to the subsequent treatment unit. After the wastewater comes out of the grit chamber, it enters the regulating tank, which is used to regulate the water quality and water volume of the wastewater. Because the amount of wastewater generated and the concentration of pollutants in the rubber roller production process fluctuate, the wastewater is kept in the regulating tank for a period of time to achieve a relatively stable water quality and water volume, creating conditions for more stable and effective subsequent treatment. After the regulating tank is the grease trap 101, the wastewater flows into the grease trap 101 through the water inlet pipe 102, and the grease in the wastewater is separated by the grease trap 101, and the separated grease can be subjected to subsequent deep treatment.

[0040] The filter 104 is relatively fine and can filter the sewage entering the grease trap 101 again, further intercepting rubber particles and other solid impurities, so as to prevent the impurities from absorbing grease or forming precipitation with the grease, causing the grease to be unable to float normally, and then causing the grease to be unable to be completely separated from the sewage.

[0041] Specifically, the cleaning component 200 is arranged on the water inlet pipe 102, and includes a flushing part 201. The flushing part 201 includes a water injection pipe 201a. The water injection pipe 201a is fixed to the top of the water inlet pipe 102. A water storage tank 201b is fixed to the top of the water injection pipe 201a. A pressure plate 201c is arranged in the water storage tank 201b. A first spring 201d is fixed to the top of the pressure plate 201c. A support frame 201e is fixed to the top of the water storage tank 201b. The top of the first spring 201d is fixed to the support frame 201e.

[0042] The water tank 201b is used to store cleaning water. A water injection hole and a valve are provided at a lower position on one side of the water tank 201b, so that water can be added to the inside of the water tank 201b.

[0043] When the filter 104 needs to be backwashed, the first spring 201d applies a downward thrust to the pressure plate 201c, and the cleaning water inside the water tank 201b is squeezed into the water injection pipe 201a through the pressure plate 201c, so that the cleaning water entering the water inlet pipe 102 can have sufficient pressure, and the filter 104 can be backwashed by the cleaning water, thereby avoiding serious blockage of the filter 104, which will affect the normal flow of sewage into the grease trap 101.

[0044] Specifically, the cleaning component 200 also includes a blocking member 202, which includes a fixing ring 202a, which is fixed in the water inlet pipe 102 and located on one side of the filter screen 104. A baffle 202b is provided on one side of the fixing ring 202a, a positioning frame 202c is fixed in the water inlet pipe 102, a positioning column 202d is fixed on one side of the baffle 202b, and the positioning column 202d is movably connected to the positioning frame 202c, a second spring 202e is fixed on one side of the baffle 202b, and the other end of the second spring 202e is fixed to the positioning frame 202c.

[0045] The baffle 202b is positioned by the cooperation of the positioning frame 202c and the positioning column 202d to prevent the baffle 202b from being offset when moving. When the sewage inside the water inlet pipe 102 flows, the baffle 202b is pushed to move, so that the baffle 202b is separated from the fixing ring 202a, so that the sewage can flow into the grease trap 101.

[0046] When the filter 104 is clogged after being used for a long time, the flow of sewage passing through the filter 104 becomes less, and the thrust applied to the baffle 202b is reduced. At this time, the baffle 202b is pushed to move by the second spring 202e, so that the baffle 202b is close to the fixing ring 202a. When the baffle 202b is in contact with the fixing ring 202a, the cleaning water can be transported to the inside of the water inlet pipe 102 through the water injection pipe 201a, and the filter 104 is backwashed. At this time, the cleaning water flowing into the water inlet pipe 102 can be intercepted by the baffle 202b, so that it cannot flow into the grease trap 101, and only the filter 104 can be cleaned.

[0047] Specifically, the cleaning component 200 also includes an intercepting member 203 , which includes a supporting frame 203 a , which is fixed to the top of the water inlet pipe 102 , and an intercepting plate 203 b is arranged in the supporting frame 203 a , and the intercepting plate 203 b is plugged into the water inlet pipe 102 .

[0048] Support frame 203a The support frame 203a is used to position the interception plate 203b and protect the connection between the water inlet pipe 102 and the interception plate 203b to prevent sewage from flowing out.

[0049] When the water injection pipe 201a transports cleaning water to the inside of the water inlet pipe 102, the interception plate 203b will move downward and fit into the inside of the water inlet pipe 102, thereby intercepting the sewage and preventing it from approaching the filter screen 104, thereby not affecting the cleaning of the filter screen 104.

[0050] Example 2

[0051] Reference Figure 3-Figure 11, which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0052] Specifically, the cleaning component 200 also includes a rotating member 204, which includes a fixed column 204a, which is fixed to the top of the intercepting plate 203b. A rotating sleeve 204b is provided on the top of the support frame 203a, and a fixed shaft 204c is fixed in the rotating sleeve 204b. A spiral groove 204a-1 is opened on the fixed column 204a, and the fixed shaft 204c slides in the spiral groove 204a-1.

[0053] When the rotating sleeve 204b rotates, it can drive the fixed shaft 204c to slide in the spiral groove 204a-1, and the cooperation between the two can drive the fixed column 204a to move downward, so that the fixed column 204a can drive the intercepting plate 203b to move downward and make the intercepting plate 203b fit the inside of the water inlet pipe 102.

[0054] A mounting block is fixed to the top of the fixed column 204a, and a sixth spring is fixed to the bottom of the mounting block. The bottom end of the sixth spring is fixed to the fixed sleeve 205a. When the rotating sleeve 204b stops rotating, the sixth spring applies an upward thrust to the mounting block, and drives the fixed column 204a and the intercepting plate 203b to move upward through the mounting block, so that the intercepting plate 203b can be separated from the water inlet pipe 102, and the sewage inside the water inlet pipe 102 can flow normally.

[0055] Specifically, the cleaning component 200 also includes a driving member 205, which includes a fixed sleeve 205a, the fixed sleeve 205a is fixed to the top of the support frame 203a, the rotating sleeve 204b is rotatably connected to the support frame 203a, a blade 205c is fixed to the outside of the rotating sleeve 204b, a connecting pipe 205d is fixed to one side of the fixed sleeve 205a, the other end of the connecting pipe 205d is connected to the water injection pipe 201a, and a water receiving frame 205e is fixed to the end of the connecting pipe 205d and located inside the water injection pipe 201a.

[0056] There are multiple blades 205c, which are fixed in a ring shape on the outside of the rotating sleeve 204b. When the cleaning water inside the water injection pipe 201a flows downward, part of the cleaning water is intercepted by the water receiving frame 205e and guided into the connecting pipe 205d, and then transported to the inside of the fixed sleeve 205a through the connecting pipe 205d. At this time, the cleaning water will push the blades 205c to rotate, so that the rotating sleeve 204b can be driven to rotate through the blades 205c.

[0057] A drainage pipe is fixed on one side of the fixed sleeve 205a, and the other end of the drainage pipe is connected to the water inlet pipe 102. The cleaning water inside the fixed sleeve 205a can be discharged into the water inlet pipe 102 through the drainage pipe.

[0058] Specifically, the cleaning component 200 also includes a blocking member 206, which includes a support plate 206a, which is fixed in the water injection pipe 201a, and a water baffle 206b is hinged to the top of the support plate 206a through a hinge plate, and a push column 206c is provided at the bottom of the water baffle 206b, and a force block 206d is fixed to the bottom end of the push column 206c, and an extrusion rod 206e is fixed to one side of the baffle 202b, and the extrusion rod 206e cooperates with the force block 206d.

[0059] The support plate 206a is used to support the water baffle plate 206b, which blocks and intercepts the cleaning water inside the water storage tank 201b to prevent the cleaning water from flowing downward when the filter screen 104 does not need to be cleaned, thereby causing a waste of cleaning water.

[0060] One side of the force block 206d is inclined. When the baffle plate 202b moves toward the fixing ring 202a, it will drive the extrusion rod 206e to squeeze the inclined surface of the force block 206d, pushing the force block 206d to move upward on one side, and driving the push column 206c to move upward through the force block 206d, and then the water baffle plate 206b can be pushed upward to open through the push column 206c, so that the cleaning water inside the water tank 201b can flow downward.

[0061] Specifically, the cleaning component 200 also includes an emptying part 207, and the emptying part 207 includes an emptying pipe 207a, the emptying pipe 207a is fixed at the bottom of the water inlet pipe 102, and a blocking block 207b is inserted at the top of the emptying pipe 207a, a supporting block 207c is fixed on the top of the blocking block 207b, a sliding shaft 207d is fixed on one side of the supporting block 207c, a rotating rod 207e is arranged on the top of the blocking block 207b, a sliding groove 207e-1 is opened on the rotating rod 207e, the sliding shaft 207d is slidably connected with the sliding groove 207e-1, a stabilizing rod 207f is fixed in the water inlet pipe 102, and the center of the rotating rod 207e is rotatably connected to one side of the stabilizing rod 207f through a rotating shaft, and a pressure block 207g is fixed on one side of the intercepting plate 203b.

[0062] The drain pipe 207a is connected to the water inlet pipe 102. When the filter screen 104 is being cleaned, the waste water containing solid impurities after cleaning can be drained to a designated location through the drain pipe 207a and processed centrally.

[0063] The bottom of the block 207b is conical, and the inside of the drain pipe 207a is conical. When the filter screen 104 does not need to be cleaned, the block 207b will fit inside the drain pipe 207a, thereby blocking the drain pipe 207a and preventing the pretreated sewage inside the water inlet pipe 102 from flowing out through the drain pipe 207a.

[0064] When the intercepting plate 203b moves downward to the designated position, it will drive the pressing block 207g to press one end of the rotating rod 207e downward. At this time, the other end of the rotating rod 207e drives the blocking block 207b to move upward through the cooperation of the sliding shaft 207d and the slide groove 207e-1, so that the blocking block 207b is separated from the inside of the drain pipe 207a, so that the cleaned water can be discharged outward through the drain pipe 207a.

[0065] A fixing frame is fixed inside the drain pipe 207a, and a stabilizing column is fixed at the bottom of the blocking block 207b. The stabilizing column is movably connected to the fixing frame, and the two cooperate to position the blocking block 207b to prevent the blocking block 207b from shifting when moving.

[0066] Specifically, the cleaning assembly 200 also includes a shut-off member 208, which includes a plug plate 208a, which is plugged into the bottom of the connecting pipe 205d, a third spring 208b is fixed to the bottom of the plug plate 208a, a force-bearing sleeve 208c is fixed to the bottom of the third spring 208b, and the force-bearing sleeve 208c is sleeved on the outside of the plug plate 208a.

[0067] The third spring 208b is used to connect the plug plate 208a with the force-bearing sleeve 208c. When the force-bearing sleeve 208c moves upward, the third spring 208b pushes the plug plate 208a to move upward, so that the plug plate 208a is inserted into the connecting pipe 205d and the water flow inside the connecting pipe 205d is intercepted, so that the water flow cannot flow into the fixed sleeve 205a, and the rotating sleeve 204b stops rotating.

[0068] A mounting frame is fixed on one side of the support frame 203a, and the plug plate 208a is movably connected to the mounting frame to guide and position the plug plate 208a.

[0069] Example 3

[0070] Reference Figure 1-Figure 11 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0071] Specifically, a movable groove 203b-1 is opened in the intercepting plate 203b, and a force-bearing plate 208d is arranged in the movable groove 203b-1. A fourth spring 208e is fixed to one side of the force-bearing plate 208d. A push rod 208f is inserted into the fixed column 204a, and a force-bearing rod 208g is fixed to the bottom of the push rod 208f. The bottom end of the force-bearing rod 208g extends into the movable groove 203b-1.

[0072] The force-bearing plate 208d fits tightly with the movable groove 203b-1, and a movable groove is provided on the fixed column 204a. The force-bearing rod 208g can move in the movable groove, and the end of the push rod 208f is inclined.

[0073] The fourth spring 208e has a strong elastic force. When the interception plate 203b fits against the inside of the water inlet pipe 102 and intercepts the sewage inside the water inlet pipe 102, the pressure generated by the sewage will act on the force-bearing plate 208d. As the amount of sewage on one side of the interception plate 203b increases, the force-bearing plate 208d will gradually be pushed to move. At the same time, after the filter net 104 has been cleaned for a sufficient period of time, the movement of the force-bearing plate 208d will contact the force-bearing rod 208g and push the force-bearing rod 208g to move, so that the force-bearing rod 208g drives the push rod 208f to move, and the inclined surface at the end of the push rod 208f contacts the bottom of the fixed sleeve 205a, thereby pushing the fixed sleeve 205a to move upward, and then the fixed sleeve 205a can drive the plug plate 208a to move upward.

[0074] When the intercepting plate 203b moves upward, it will drive the push rod 208f to move upward. At this time, the end of the push rod 208f is still squeezing the fixed sleeve 205a. As the push rod 208f moves upward, it will drive the fixed sleeve 205a to move upward. At this time, since the plug plate 208a cannot move upward, the fixed sleeve 205a will squeeze the third spring 208b.

[0075] Specifically, the cleaning assembly 200 further includes a locking member 209, which includes a fixing frame 209a, which is fixed in the water inlet pipe 102, a stopper 209b is provided in the fixing frame 209a, and a fifth spring 209c is fixed to the bottom of the stopper 209b.

[0076] When the baffle 202b is separated from the fixing ring 202a, the fifth spring 209c will apply a downward pulling force to the block 209b, so that the block 209b is always located inside the fixing frame 209a. When the baffle 202b is in contact with the fixing ring 202a, the block 209b will move upward and contact one side of the baffle 202b, thereby locking the baffle 202b and preventing the baffle 202b from being separated from the fixing ring 202a, thereby preventing the cleaning water from pushing the baffle 202b to open when flowing downward, thereby preventing the cleaning water from not being able to flow to the filter 104, thereby making it impossible to fully clean the filter 104.

[0077] Specifically, a moving rod 209d is inserted into the fixed frame 209a, a force groove 209b-1 is opened on the stopper 209b, the moving rod 209d cooperates with the force groove 209b-1, and an extrusion block 209f is fixed to one side of the blocking block 207b.

[0078] One side of the extrusion block 209f is inclined, the inner wall of the force-bearing groove 209b-1 is inclined, and the moving rod 209d is movably connected with the filter screen 104 and the fixing ring 202a.

[0079] When the blocking block 207b moves upward, it will drive the extrusion block 209f to squeeze the end of the moving rod 209d, thereby pushing the moving rod 209d to move, and the moving rod 209d will squeeze the inner wall slope of the force groove 209b-1. The cooperation of the two can drive the blocking block 209b to move upward.

[0080] Specifically, a stabilizing frame 206f is fixed inside the water injection pipe 201a, and a positioning block 206g is fixed outside the push column 206c.

[0081] The push post 206c is movably connected to the stabilizing frame 206f. The push post 206c is positioned by the stabilizing frame 206f to prevent it from tilting during movement. The push post 206c is supported by the positioning block 206g to prevent it from falling downward.

[0082] When in use, after the washing wastewater is discharged, it first passes through the screen to remove larger rubber particles, debris and other suspended matter in the wastewater to prevent these large particles from entering the subsequent treatment equipment and causing equipment blockage. After passing through the screen, the wastewater flows into the grit tank, whose main purpose is to precipitate inorganic sand particles and heavier solid impurities in the wastewater. These impurities settle to the bottom of the tank by gravity, and the wastewater that has undergone preliminary sand removal continues to flow to the subsequent treatment unit. After the wastewater comes out of the grit tank, it enters the regulating tank, which is used to regulate the water quality and water volume of the wastewater. Because the amount of wastewater generated and the concentration of pollutants in the rubber roller production process fluctuate, by stopping in the regulating tank Leave it for a while so that the water quality and quantity of the sewage can reach a relatively stable state, creating conditions for subsequent more stable and effective treatment. After the regulating tank is the grease trap 101, the sewage flows into the grease trap 101 through the water inlet pipe 102, and the grease in the sewage is separated by the grease trap 101. The separated grease can be subjected to subsequent deep treatment, and the sewage entering the grease trap 101 is filtered again through the filter net 104 to further intercept rubber particles and other solid impurities, so as to prevent the impurities from absorbing grease, or forming precipitation together with grease, which makes it impossible for the grease to float normally, and then makes it impossible for the grease to be completely separated from the sewage.

[0083] When the filter 104 is clogged after being used for a long time, the flow of sewage passing through the filter 104 becomes less, and the thrust applied to the baffle 202b is reduced. At this time, the baffle 202b is pushed to move by the second spring 202e, so that the baffle 202b is close to the fixing ring 202a. When the baffle 202b moves toward the fixing ring 202a, it will drive the extrusion rod 206e to squeeze the inclined surface of the force block 206d, and one side pushes the force block 206d to move upward, and drives the push column 206c to move upward through the force block 206d, and then the water baffle 206b can be pushed upward to open through the push column 206c, so that the cleaning water inside the water tank 201b can flow downward.

[0084] At the same time, when the cleaning water inside the water injection pipe 201a flows downward, part of the cleaning water is intercepted by the water receiving frame 205e and guided into the connecting pipe 205d, and then transported to the inner side of the fixed sleeve 205a through the connecting pipe 205d. At this time, the cleaning water will push the blade 205c to rotate, so that the rotating sleeve 204b can be driven to rotate through the blade 205c. When the rotating sleeve 204b rotates, it can drive the fixed shaft 204c to slide in the spiral groove 204a-1, and the fixed column 204a is driven to move downward through the cooperation of the two. Therefore, the fixed column 204a can drive the interception plate 203b to move downward, and the interception plate 203b can fit with the inside of the water inlet pipe 102, so as to intercept the sewage and prevent the sewage from approaching the filter 104, thereby not affecting the cleaning of the filter 104.

[0085] At the same time, the first spring 201d applies a downward thrust to the pressure plate 201c, and the cleaning water inside the water tank 201b is squeezed into the water injection pipe 201a through the pressure plate 201c, so that the cleaning water entering the water inlet pipe 102 can have sufficient pressure, and the filter screen 104 can be backwashed by the cleaning water, so as to avoid serious blockage of the filter screen 104, which will affect the normal flow of sewage into the grease trap 101.

[0086] When the intercepting plate 203b moves downward to the designated position, it will drive the pressing block 207g to press one end of the rotating rod 207e downward. At this time, the other end of the rotating rod 207e drives the blocking block 207b to move upward through the cooperation of the sliding shaft 207d and the slide groove 207e-1, so that the blocking block 207b is separated from the inside of the drain pipe 207a, so that the cleaned water can be discharged outward through the drain pipe 207a.

[0087] When the interception plate 203b fits with the inside of the water inlet pipe 102 and intercepts the sewage inside the water inlet pipe 102, the pressure generated by the sewage will act on the force-bearing plate 208d. As the amount of sewage on one side of the interception plate 203b increases, the force-bearing plate 208d will be gradually pushed to move. At the same time, after the filter screen 104 has been cleaned for a sufficient period of time, the movement of the force-bearing plate 208d will contact the force-bearing rod 208g and push the force-bearing rod 208g to move, so that the force-bearing rod 208g drives the push rod 208f to move, and the inclined surface of the end of the push rod 208f contacts the bottom of the fixed sleeve 205a, thereby pushing the fixed sleeve 205a to move upward, and then the fixed sleeve 205a can drive the plug plate 208a to move upward, so that the plug plate 208a is inserted into the connecting pipe 205d and intercepts the water flow inside the connecting pipe 205d, so that the water flow cannot flow into the fixed sleeve 205a, and then the rotating sleeve 204b can stop rotating.

[0088] When the rotating sleeve 204b stops rotating, the sixth spring applies an upward thrust to the mounting block, and the mounting block drives the fixed column 204a and the intercepting plate 203b to move upward, so that the intercepting plate 203b can be separated from the water inlet pipe 102, and the sewage inside the water inlet pipe 102 can flow normally. At this time, the sewage will push the baffle 202b to move, so that the baffle 202b is separated from the fixed ring 202a, and the extrusion rod 206e will separate from the force block 206d, thereby releasing the support for the baffle 206b, and the baffle 206b is closed downward, and the cleaning water inside the water storage tank 201b is blocked again.
