Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage treatment, in particular to a sewage treatment device and method based on urban ecological environment governance. BACKGROUND

[0002] With the acceleration of urbanization, the urban population is growing rapidly, and industrial activities are becoming more frequent. The amount of urban sewage is showing explosive growth. At the same time, people's requirements for water environmental quality are also constantly improving, which makes urban sewage treatment a key link to ensure the sustainable development of urban ecological environment. Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging to a water body or for reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering and other fields, and is increasingly entering the daily life of ordinary people.

[0003] Publication No. CN120247347A discloses a kind of urban sewage treatment device, it relates to the field of sewage treatment, including processing box, still including: the pre-treatment unit of separating large particle impurities in sewage, the compound biological reaction unit of organic degradation and nitrogen phosphorus conversion to the sewage after pre-treatment unit and further remove nano adsorption unit of small pollutants and heavy metal ions;The processing box is close to nano adsorption unit place and is provided with dismounting plate, the top of the processing box is provided with liquid pumping machine one, the outer surface of the liquid pumping machine one is provided with water pipe one towards compound biological reaction unit, the outer surface of the liquid pumping machine one is also provided with the spraying device with high pressure nozzle towards nano adsorption unit, sewage will first remove large particle impurities through pre-treatment unit, then enter compound biological unit after being organic degradation, finally, further remove small pollutants and heavy metal ions by entering nano adsorption unit through liquid pumping machine one, to realize multiple processing.

[0004] Although the above application and prior art can perform multiple processing on sewage, but when treating urban sewage in the above application and prior art, since the urban sewage may contain hair, the hair will gather together and block the intercepting guardrail when the impurities in the sewage are connected, so the intercepting guardrail needs to be treated multiple times, and since the hair will be wound on the surface of the intercepting guardrail during reverse flushing of the guardrail, a small amount of hair will still remain, and the small amount of remaining hair will again cause the hair to gather, thereby causing the intercepting guardrail to be blocked again, and when the hair on the surface of the intercepting guardrail is treated, the falling hair will again enter the pool, causing the hair to enter the subsequent processing step with the sewage, thereby affecting the subsequent processing. Therefore, the present application proposes a sewage treatment device and method based on urban ecological environment governance. SUMMARY

[0005] (1) Technical problem solved

[0006] To address the shortcomings of existing technologies, this invention provides a wastewater treatment device and method for urban ecological environment governance, which has advantages such as backwashing, anti-entanglement, and anti-flow. It solves the problems in the aforementioned applications and existing technologies where, during the treatment of urban wastewater, the presence of hair causes it to clump together and clog the intercepting barriers when connecting impurities in the wastewater. This necessitates multiple treatments of the barriers. Furthermore, during backwashing, hair remains on the barrier surface, causing further hair accumulation and clogging. Additionally, hair falling off the barrier surface during treatment re-enters the water tank, entering subsequent treatment steps with the wastewater and affecting subsequent processes.

[0007] (II) Technical Solution

[0008] To achieve the aforementioned objectives of reverse flushing, preventing entanglement, and preventing inflow, this invention provides the following technical solution: a wastewater treatment device for urban ecological environment management, comprising: a treatment tank and an interception frame rotatably connected inside the treatment tank.

[0009] A drive housing is fixedly connected to the back of the treatment tank. A sedimentation tank is provided at one end of the treatment tank, and the sedimentation tank and the treatment tank are connected by a connecting pipe.

[0010] A backwash assembly, located inside the treatment tank, is used to backwash the hair on the surface of the interception frame to prevent hair from clogging the interception frame. The backwash assembly includes a drive motor fixedly connected inside the drive housing. A drive rod is fixedly connected to the output end of the drive motor. The end of the drive rod away from the drive motor is fixedly connected to one end of the interception frame. Several connecting strips are fixedly connected inside the interception frame.

[0011] An anti-tangling component, disposed inside the processing pool, is used to remove hair tangled on the surface of several connecting strips;

[0012] An interception component, located inside the processing pool, is used to intercept hair after it has been processed by the recoil component and the anti-tangling component.

[0013] Furthermore, the recoil assembly also includes a telescopic rod disposed inside the interception frame, the telescopic rod having a first spring disposed inside it, and a blocking frame fixedly connected to one end of the telescopic rod.

[0014] Furthermore, a placement box is fixedly connected to the top of the treatment pool, and an adjustment box is fixedly connected to the top of the placement box. The anti-tangling component includes a rotating rod rotatably connected inside the adjustment box and a storage cylinder fixedly connected inside the adjustment box. A half gear is fixedly connected to the surface of the rotating rod, and a release rack is slidably connected inside the storage cylinder. The release rack meshes with the half gear for transmission, and the rotating rod and the drive rod are transmitted through a first transmission mechanism.

[0015] Furthermore, the anti-tangling component also includes an air supply cylinder fixedly connected inside the regulating box and an air storage cylinder fixedly connected inside the regulating box. A disk is embedded inside the air supply cylinder, and a sealing iron plate is slidably connected inside the air supply cylinder. A push rod is fixedly connected to the bottom of the sealing iron plate, and a floating ball is fixedly connected to the bottom of the push rod.

[0016] Furthermore, the gas delivery cylinder and the gas storage cylinder are connected by an air inlet pipe, and a first one-way valve is provided on the surface of the air inlet pipe.

[0017] Furthermore, the anti-entanglement component also includes several telescopic cylinders fixedly connected inside the interception frame. The telescopic cylinders are connected to the air storage cylinder through an air outlet pipe, and a pressure relief valve is provided on the surface of the air outlet pipe.

[0018] Furthermore, a push plate is fixedly connected to one end of several of the telescopic cylinders, the push plate is slidably connected to the surface of the connecting strip, and a push rod is fixedly connected to the end of the push plate away from the telescopic cylinder.

[0019] Furthermore, the interception assembly includes a fixed rod rotatably connected inside the drive housing and a rotating rod rotatably connected inside the processing pool. A ratchet is fixedly connected to the surface of the rotating rod, and the rotating rod and the drive rod are driven by a second transmission mechanism.

[0020] Furthermore, a plurality of intercepting filter screens are fixedly connected to the surface of the fixed rod and inside the treatment pool. A fixed disk is fixedly connected to one end of the fixed rod. A pawl is rotatably connected inside the fixed disk. The ratchet is located inside the fixed disk and engages with the pawl.

[0021] This invention also provides a wastewater treatment method for urban ecological environment governance, which specifically includes the following steps:

[0022] Step 1: Discharge the wastewater containing hair into the treatment tank, where the hair in the wastewater is intercepted by several connecting strips inside the interception frame;

[0023] Step 2: When it is necessary to prevent hair from clogging the connecting strips inside the interception box, the interception box is flipped over by the backwash component, so that the sewage can flush the interception box in a specific direction.

[0024] Step 3: When it is necessary to remove the hair wrapped around the surface of the connecting strip, the anti-tangling component is driven synchronously when the recoil component is operating, so that the anti-tangling component removes the hair wrapped around the surface of the connecting strip.

[0025] Step 4: When it is necessary to avoid the processed hair from affecting subsequent processing, the backflush component operates in sync with the interception component, so that the interception component transfers the hair out of the processing pool.

[0026] Step 5: After being treated in the treatment tank, the wastewater enters the sedimentation tank through the connecting pipe, where it undergoes sedimentation treatment.

[0027] (III) Beneficial Effects

[0028] Compared with the prior art, the present invention provides a wastewater treatment device and method for urban ecological environment governance, which has the following beneficial effects:

[0029] 1. The wastewater treatment device and method for urban ecological environment governance utilizes a backwashing component. When hair clogs the surface of the connecting strip, the drive motor is activated. The drive motor drives the interception frame to rotate via the drive rod, causing the interception frame to rotate and the connecting strip to rotate. This causes the unblocked end of the interception frame to face the wastewater inlet, allowing the wastewater to flush the interception frame and wash away the hair on the surface of the connecting strip, thus achieving the effect of backwashing.

[0030] 2. This wastewater treatment device and method for urban ecological environment governance utilizes a backflushing component and an anti-entanglement component. When the drive rod rotates, it drives the rotating rod through the first transmission mechanism. This causes the rotating rod to move the detached rack out of the inside of the receiving cylinder via a half-gear. As the rack moves, the sealing iron disc separates from the disk, and the sealing iron disc, through the push rod, causes the suspended ball to fall onto the surface of the wastewater. As wastewater is continuously injected into the treatment tank, the wastewater, through the suspended ball and the push rod, causes the sealing iron disc to rise and fall continuously. This, in turn, transports the air inside the air delivery cylinder to the inside of the air storage cylinder through the air inlet pipe. When the air inside the air storage cylinder reaches a set threshold, the air inside the air storage cylinder is transported to the inside of the telescopic cylinder through the air outlet pipe. This causes the telescopic cylinder to move the push plate and push rod. During the movement, the push plate scrapes off the hair wrapped around the surface of the connecting strip, preventing the hair from getting tangled on the surface of the connecting strip, thus achieving the effect of preventing entanglement.

[0031] 3. This wastewater treatment device and method for urban ecological environment governance utilizes the combined use of a backwash component and an interception component. When the drive rod rotates the interception frame, it also drives the rotating rod to rotate via a second transmission mechanism. This rotating rod then drives the pawl to rotate via a ratchet. Because the ratchet and pawl engage, the pawl drives the fixed rod to rotate via a fixed disc. This, in turn, causes the fixed rod to rotate the interception filter. Therefore, when hair on the surface of the connecting strip is cleaned, it adheres to the surface of the interception filter as the wastewater flows and is removed from the treatment tank as the filter rotates, thus preventing inflow.

The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] The devices or elements referred to in the embodiments of this application or implied herein must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0051] For a specific implementation example, please refer to Implementation Example 1. Figures 1 to 3 A wastewater treatment device for urban ecological environment management includes: a treatment tank 1 and an interception frame 22 rotatably connected inside the treatment tank 1.

[0052] The drive housing 11 is fixedly connected to the back of the treatment tank 1. A sedimentation tank 131 is provided at one end of the treatment tank 1. The sedimentation tank 131 is connected to the treatment tank 1 through a connecting pipe 13.

[0053] The backwash assembly 2 is located inside the treatment pool 1 and is used to backwash the hair on the surface of the interception frame 22 to prevent hair from clogging the interception frame 22. The backwash assembly 2 includes a drive motor 21 fixedly connected inside the drive housing 11. A drive rod 211 is fixedly connected to the output end of the drive motor 21. The end of the drive rod 211 away from the drive motor 21 is fixedly connected to one end of the interception frame 22. Several connecting strips 221 are fixedly connected inside the interception frame 22.

[0054] The anti-tangling component 3 is disposed inside the processing pool 1 and is used to remove hair tangled on the surface of several connecting strips 221;

[0055] The interception component 4 is located inside the processing pool 1 and is used to intercept the hair processed by the recoil component 2 and the anti-tangling component 3.

[0056] It should be noted that the end of the treatment tank 1 away from the connecting pipe 13 is fixedly connected to an inlet, and the volume of the sedimentation tank 131 is larger than the volume of the treatment tank 1.

[0057] When sewage needs to be treated, sewage is injected into treatment tank 1 through the inlet, so that impurities in the sewage are intercepted by the connecting strip 221 inside the interception frame 22, thus performing preliminary treatment on the sewage. As sewage is continuously injected into treatment tank 1, the sewage treated by the interception frame 22 enters the interior of sedimentation tank 131 through the connecting pipe 13, so that the fine impurities in the sewage are settled in sedimentation tank 131, thus treating the sewage again.

[0058] For a specific embodiment two, please refer to Figures 1 to 4 Based on the wastewater treatment device for urban ecological environment management provided in Specific Embodiment 1, this embodiment provides a further technical solution:

[0059] The recoil assembly 2 also includes a telescopic rod 222 disposed inside the interception frame 22. The telescopic rod 222 is provided with a first spring inside, and a blocking frame 223 is fixedly connected to one end of the telescopic rod 222.

[0060] When the surface of the connecting strip 221 is blocked by hair in the sewage, the drive motor 21 is started. The drive motor 21 drives the intercepting frame 22 to rotate through the drive rod 211. The intercepting frame 22 drives the connecting strip 221 to rotate, so that the unblocked end of the intercepting frame 22 faces the sewage inlet. The flow of sewage flushes the intercepting frame 22, and the hair on the surface of the connecting strip 221 is washed off by the flow of sewage. Thus, the hair no longer blocks the connecting strip 221 inside the intercepting frame 22, so that the impurities in the sewage can be quickly intercepted. Therefore, it is no longer necessary to disassemble the entire connecting frame 22 for processing. After the reverse flushing is completed, the drive motor 21 is started again. The drive motor 21 drives the intercepting frame 22 to reverse through the drive rod 211, so that the intercepting frame 22 drives the connecting strip 221 back to the initial state.

[0061] For a specific embodiment three, please refer to Figures 1 to 11 Based on the wastewater treatment device for urban ecological environment management provided in Specific Embodiment 2, this embodiment provides a further technical solution:

[0062] A placement box 12 is fixedly connected to the top of the treatment tank 1, and an adjustment box 121 is fixedly connected to the top of the placement box 12. The anti-tangling component 3 includes a rotating rod 31 rotatably connected inside the adjustment box 121 and a storage cylinder 32 fixedly connected inside the adjustment box 121. A half gear 311 is fixedly connected to the surface of the rotating rod 31, and a disengagement rack 321 is slidably connected inside the storage cylinder 32. The disengagement rack 321 meshes with the half gear 311 for transmission. The rotating rod 31 and the drive rod 211 are transmitted through a first transmission mechanism 312. The anti-tangling component 3 also includes an air supply cylinder 33 fixedly connected inside the adjustment box 121 and an air storage cylinder 34 fixedly connected inside the adjustment box 121. A disk 331 is embedded inside the air supply cylinder 33. A sealing iron plate 332 is slidably connected to the part, and a push rod 333 is fixedly connected to the bottom of the sealing iron plate 332. A floating ball 334 is fixedly connected to the bottom of the push rod 333. The air supply cylinder 33 and the air storage cylinder 34 are connected through an air inlet pipe 335. A first one-way valve 336 is provided on the surface of the air inlet pipe 335. The anti-entanglement component 3 also includes several telescopic cylinders 35 fixedly connected inside the interception frame 22. The several telescopic cylinders 35 are connected to the air storage cylinder 34 through an air outlet pipe 341. A pressure relief valve is provided on the surface of the air outlet pipe 341. A push plate 351 is fixedly connected to one end of the several telescopic cylinders 35. The push plate 351 is slidably connected to the surface of the connecting strip 221. A push rod 352 is fixedly connected to the end of the push plate 351 away from the telescopic cylinder 35.

[0063] It should be noted that a second one-way valve is provided on the surface of the air delivery cylinder 33. When the sealing iron plate 332 descends, the second one-way valve opens, allowing outside air to be transmitted to the interior of the air delivery cylinder 33. When the sealing iron plate 332 rises, the second one-way valve closes, allowing the air inside the air delivery cylinder 33 to be transported to the interior of the air storage cylinder 34 through the air inlet pipe 335. The first transmission mechanism 312 includes a first driving sprocket fixedly connected to the surface of the drive rod 211 and a first driven sprocket fixedly connected to the surface of the rotating rod 31. The first driving sprocket and the first driven sprocket are driven by a first chain.

[0064] When hair wrapped around the surface of the connecting strip 221 needs to be removed, when the drive rod 211 drives the intercepting frame 22 to rotate, the drive rod 211 drives the rotating rod 31 to rotate through the first transmission mechanism 312. This causes the rotating rod 31 to drive the disengaging rack 321 out of the inside of the receiving cylinder 32 through the half gear 311. As the disengaging rack 321 moves, it separates the sealing iron plate 332 from the disk 331. This causes the sealing iron plate 332 to be pushed by the push rod 333, which in turn drives the suspended ball 334 to fall onto the surface of the sewage. As sewage is continuously injected into the treatment tank 1, the sewage is pushed by the suspended ball 334 and the push rod 333, which in turn drives the sealing iron plate 332 to the air conveyor 3. 3. The internal structure continuously rises and falls, thereby transporting the air inside the air delivery cylinder 33 to the inside of the air storage cylinder 34 through the air inlet pipe 335. When the air inside the air storage cylinder 34 reaches a set threshold, the air inside the air storage cylinder 34 is transported to the inside of the telescopic cylinder 35 through the air outlet pipe 341, causing the telescopic cylinder 35 to drive the push plate 351 and the push rod 352 to move. During the movement, the push plate 351 scrapes off the hair wrapped around the surface of the connecting strip 221, so that the hair is no longer wrapped around the surface of the connecting strip 221. During the rise of the push plate 351, the push plate 351 drives the blocking frame 223 to rise through the push rod 352, so that the blocking frame 223 does not affect the removal of the wrapped hair.

[0065] For a specific implementation example, please refer to Implementation Example 4. Figures 1 to 15 Based on the wastewater treatment device for urban ecological environment management provided in Specific Embodiment 3, this embodiment provides a further technical solution:

[0066] The interception assembly 4 includes a fixed rod 41 rotatably connected inside the drive housing 11 and a rotating rod 42 rotatably connected inside the treatment tank 1. A ratchet 421 is fixedly connected to the surface of the rotating rod 42. The rotating rod 42 and the drive rod 211 are driven by a second transmission mechanism 422. Several interception filters 413 are fixedly connected to the surface of the fixed rod 41 and inside the treatment tank 1. A fixed disk 411 is fixedly connected to one end of the fixed rod 41. A pawl 412 is rotatably connected inside the fixed disk 411. The ratchet 421 is located inside the fixed disk 411 and meshes with the pawl 412.

[0067] It should be noted that a recycling box is slidably connected inside the treatment pool 1 near the connecting pipe 13. When the intercepting filter 413 rotates continuously, the hair attached to the top of the intercepting filter 413 can fall into the recycling box as the intercepting filter 413 rotates. The second transmission mechanism 422 includes a second driving sprocket fixedly connected to the surface of the drive rod 211 and a second driven sprocket fixedly connected to the surface of the rotating rod 42. The second driving sprocket and the second driven sprocket are driven by a second chain.

[0068] When it is necessary to prevent fallen hair from flowing into the sedimentation tank 131, when the drive rod 211 drives the interception frame 22 to rotate, the drive rod 211 drives the rotating rod 42 to rotate through the second transmission mechanism 422, so that the rotating rod 42 drives the pawl 412 to rotate through the ratchet 421. Since the ratchet 421 and the pawl 412 are engaged, the pawl 412 drives the fixed rod 41 to rotate through the fixed plate 411, which in turn drives the interception filter screen 413 to rotate. Therefore, when the hair on the surface of the connecting strip 221 is cleaned, the hair will adhere to the surface of the interception filter screen 413 with the flow of sewage, and be removed from the treatment tank 1 as the interception filter screen 413 rotates.

[0069] In a specific embodiment five, the present invention also provides a wastewater treatment method for urban ecological environment governance, which specifically includes the following steps:

[0070] Step 1: Discharge the wastewater containing hair into the treatment tank 1, and intercept the hair in the wastewater through several connecting strips 221 inside the interception frame 22;

[0071] Step 2: When it is necessary to prevent hair from clogging the connecting strips 221 inside the interception box 22, the interception box 22 is flipped over by the backwash assembly 2 so that the sewage can flush the interception box 22 in a directional manner.

[0072] Step 3: When it is necessary to process the hair wrapped around the surface of the connecting strip 221, the anti-tangling component 3 is driven synchronously when the recoil component 2 is operating, so that the anti-tangling component 3 removes the hair wrapped around the surface of the connecting strip 221.

[0073] Step 4: When it is necessary to avoid the processed hair from affecting subsequent processing, the backflush component 2 operates in sync with the interception component 4, so that the interception component 4 transfers the hair out of the processing pool 1.

[0074] Step 5: After being treated in treatment tank 1, the wastewater enters sedimentation tank 131 through connecting pipe 13, where sedimentation tank 131 performs sedimentation treatment on the wastewater.

[0075] Working Principle: During operation, wastewater is injected into treatment tank 1 through the inlet. Impurities in the wastewater are intercepted by the connecting strip 221 inside the interceptor frame 22, thus performing preliminary treatment. As wastewater continues to be injected into treatment tank 1, the wastewater treated by the interceptor frame 22 enters the sedimentation tank 131 through the connecting pipe 13, where fine impurities settle, thus further treating the wastewater. When the surface of the connecting strip 221 is blocked by hair in the wastewater, the drive motor 21 is started. The drive motor 21 drives the interceptor frame 22 to rotate via the drive rod 211, causing the interceptor frame 22 to rotate and the connecting strip 221 to rotate, thus turning the unblocked end of the interceptor frame 22 towards the wastewater inlet. The water inlet, through the flow of sewage, flushes the interception frame 22, causing hair on the surface of the connecting strip 221 to be washed off, thus preventing hair from clogging the connecting strip 221 inside the interception frame 22. This allows impurities in the sewage to be quickly intercepted. When it is necessary to remove hair wrapped around the surface of the connecting strip 221, when the drive rod 211 drives the interception frame 22 to rotate, the drive rod 211 drives the rotating rod 31 to rotate through the first transmission mechanism 312. The rotating rod 31, through the half gear 311, drives the release rack 321 to move out of the inside of the collection cylinder 32. As the release rack 321 moves, it separates the sealing iron plate 332 from the disk 331, thereby allowing the sealing iron plate 332 to be pushed by the push rod 333. The suspended ball 334 is brought to the surface of the sewage. As the sewage is continuously injected into the treatment tank 1, the sewage, through the suspended ball 334 and the push rod 333, causes the sealed iron plate 332 to rise and fall continuously inside the air delivery cylinder 33. This, in turn, transports the air inside the air delivery cylinder 33 to the air storage cylinder 34 through the air inlet pipe 335. When the air inside the air storage cylinder 34 reaches a set threshold, the air inside the air storage cylinder 34 is transported to the telescopic cylinder 35 through the air outlet pipe 341. This causes the telescopic cylinder 35 to move the push plate 351 and the push rod 352. During the movement, the push plate 351 scrapes off the hair wrapped around the surface of the connecting strip 221, preventing the hair from getting tangled on the surface of the connecting strip 221. During the upward movement of the push plate 351... In the process, the push plate 351 drives the blocking frame 223 to rise via the push rod 352, ensuring that the blocking frame 223 does not hinder the removal of tangled hair. When it is necessary to prevent fallen hair from flowing into the sedimentation tank 131, the drive rod 211 drives the intercepting frame 22 to rotate. Simultaneously, the drive rod 211 drives the rotating rod 42 to rotate via the second transmission mechanism 422. The rotating rod 42 drives the pawl 412 to rotate via the ratchet 421. Since the ratchet 421 and the pawl 412 are engaged, the pawl 412 drives the fixed rod 41 to rotate via the fixed plate 411. In turn, the fixed rod 41 drives the intercepting filter screen 413 to rotate. Therefore, after the hair on the surface of the connecting strip 221 is cleaned, the hair will adhere to the surface of the intercepting filter screen 413 with the flow of sewage.As the intercepting filter 413 rotates, it is removed from the interior of the treatment tank 1.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0078] Parallelism: The parallelism defined in this application is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism. It allows for situations where the parallelism is not absolute due to factors such as assembly tolerance, design tolerance, and structural flatness. It also allows for errors within a small angular range, such as within 10 degrees of assembly error. These can all be considered as parallel relationships.

[0079] Perpendicularity: The perpendicularity defined in this application is not limited to an absolute perpendicular intersection (with an included angle of 90 degrees). It is permissible for non-absolute perpendicular intersections caused by factors such as assembly tolerances, design tolerances, and structural flatness. It is permissible for errors within a small angular range, such as an assembly error range of 80 to 100 degrees, which can all be understood as a perpendicular relationship.

[0080] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
