Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment device with a crushing function. Background Technology

[0002] In the field of wastewater treatment, for wastewater containing solid impurities, existing technologies typically employ treatment devices consisting of simple filtration units, sedimentation tanks, and basic pipelines. While some devices are equipped with preliminary crushing structures, the overall treatment process and efficiency remain limited. In practice, workers first introduce wastewater into a pretreatment tank. If the wastewater contains large impurities, these need to be broken up manually or with simple crushing equipment. The pretreated wastewater is then pumped into the filtration unit for preliminary filtration using a filter screen. The filtered wastewater is then sent to a sedimentation tank, where fine impurities settle naturally over a long period. Finally, the clarified wastewater is discharged, completing the wastewater treatment process. Impurities trapped by the filtration unit require disassembling the filter screen frame for cleaning; sediment at the bottom of the sedimentation tank needs to be manually removed periodically, making the operation cumbersome.

[0003] However, existing wastewater treatment devices have significant shortcomings, making it difficult to meet the demands for efficient and thorough treatment. Firstly, solid-liquid separation efficiency is low and ineffective. Traditional devices often rely on static sedimentation or fixed-screen filtration. Static sedimentation consumes a significant amount of time, and fine impurities easily remain suspended in the wastewater, making complete separation difficult. With fixed-screen filtration, impurities easily adhere to the filter surface, causing blockage and a gradual decrease in filtration speed. If the impurity particles in the wastewater are uneven, filter pore size mismatch issues arise, either failing to trap fine impurities or allowing large impurities to clog the filter, further affecting the separation effect and preventing rapid and precise separation of wastewater and impurities. Secondly, the separation process suffers from poor stability. Traditional filtration units lack active separation power, relying solely on gravity-driven filtration. When wastewater flow fluctuates, the filtration effect is easily affected, leading to impurities penetrating the filter or wastewater overflowing. Static sedimentation is significantly affected by factors such as ambient temperature and wastewater flow rate, making it difficult to guarantee consistent separation results. This results in unstable residual impurities in the treated wastewater, failing to meet the requirements for high-quality wastewater treatment. Utility Model Content

[0004] The problem this invention aims to solve is to provide a wastewater treatment device with a crushing function. This invention has excellent solid-liquid separation effect, can quickly separate wastewater from crushed impurities, and the separation process is stable and reliable. The bottom of the separation frame is triangular prism-shaped, which can prevent the accumulation of wastewater and impurities when shaking, and allows wastewater to pass through smoothly through its own screening structure, while accurately intercepting the crushed impurities, thus achieving efficient solid-liquid separation. Compared with traditional static sedimentation or simple filtration methods, this active shaking separation design has a faster separation speed and a more thorough effect, significantly reducing the amount of residual impurities in wastewater and improving the quality of wastewater treatment.

[0005] The technical solution provided by this utility model to solve the above problems is as follows: a sewage treatment device with a crushing function, including a first mounting frame, a driving component, a crushing component, a first side plate of a flow guiding structure, and a locking component. The crushing component is installed inside the first mounting frame and is used to crush impurities in the sewage. The crushing component can rotate. The driving component is installed on the side of the first mounting frame and on the crushing component and is used to drive the crushing component to rotate in opposite directions. Two flow guiding structures are fixed to the upper and lower sides inside the first mounting frame. The first side plate is hinged inside the first mounting frame. The locking component is installed on the first mounting frame to lock and limit the first side plate. It also includes a solid-liquid separation mechanism and an auxiliary buffer mechanism. The solid-liquid separation mechanism is used to divert the crushed impurities in the sewage. The auxiliary buffer mechanism buffers the solid-liquid separation mechanism during screening.

[0006] More preferably, the flow guiding structure is a frame composed of two inverted octaves.

[0007] More preferably, the solid-liquid separation mechanism includes a second mounting frame, a motor, a turntable, a contact element, a guide element, a support plate, a first damper, a first spring, a second side plate, and a separation frame. The second mounting frame is fixed inside the first mounting frame. The motor is fixed to the side of the second mounting frame by bolts. The turntable is fixed to the output shaft of the motor. The side of the turntable has a protruding round rod. The guide element is fixed to the second mounting frame. The contact element is slidably connected to the guide element. Several first dampers are symmetrically slidably connected inside the second mounting frame. Symmetrically arranged support plates are connected to the inner side of the first dampers. Symmetrically arranged first springs are connected between the outer side of the support plate and the inner side of the second mounting frame. The second side plate is hinged to the side of the second mounting frame. The separation frame is placed between the support plates.

[0008] More preferably, the middle part of the contact element is a frame, and the protruding round rod on the turntable is located in the frame of the middle part of the contact element.

[0009] More preferably, the auxiliary buffer mechanism includes a mounting base, a contact plate, a second damper, and a second spring. The second damper is slidably connected to the mounting base, the end of the second damper is fixedly connected to the contact plate, and the second spring is connected between the contact plate and the mounting base.

[0010] More preferably, there are four auxiliary buffer mechanisms, which are respectively fixed to the side of the second side plate and the inner wall of the second mounting frame via mounting bases.

[0011] Compared with the prior art, the advantages of this utility model are: the solid-liquid separation effect of this utility model is excellent, which can quickly separate sewage from crushed impurities, and the separation process is stable and reliable. The bottom of the separation frame is triangular prism-shaped, which can avoid the accumulation of sewage and impurities when shaking, and can also allow sewage to pass through smoothly through its own screening structure, while accurately intercepting the crushed impurities, thus achieving efficient solid-liquid separation. This active shaking separation design is faster and more thorough than traditional static sedimentation or simple filtration methods, which can significantly reduce the amount of impurities remaining in sewage and improve the quality of sewage treatment.

[0012] It possesses excellent buffering protection capabilities, reducing component wear and extending the service life of the device. At the same time, it ensures the stability of the separation process. The four auxiliary buffering mechanisms are respectively fixed to the side of the second side plate and the inner wall of the second mounting frame through mounting bases. The second damper and the second spring in each auxiliary buffering mechanism work together to effectively prevent the separation frame from directly impacting the inner wall of the second mounting frame or the second side plate, reducing the hard collision wear between the separation frame and surrounding components, lowering the probability of component damage, and extending the overall service life of the device. The buffering effect keeps the separation frame in a stable shaking state, preventing the separation frame from shifting or tipping over due to excessive shaking amplitude, ensuring that the solid-liquid separation process is not affected, and guaranteeing separation efficiency and effect.

[0013] Maintenance and cleaning operations are convenient, reducing manual labor intensity and ensuring continuous and stable operation of the device. When cleaning impurities trapped in the separation frame, simply rotate the second side plate hinged to the second mounting frame to directly remove the separation frame from between the support plates. After cleaning, it can be put back without disassembling complex structures, greatly reducing the labor intensity and operation time of manual cleaning, allowing staff to complete maintenance and cleaning work more quickly, ensuring that the device is always in good working condition, reducing downtime caused by untimely maintenance and cleaning, and improving the overall operating efficiency of the device.

[0026] Example: As shown in the attached drawings, a wastewater treatment device with a crushing function includes a first mounting frame 1, a driving component 2, a crushing component 3, a flow guiding structure 4, a first side plate 5, and a locking component 6. The crushing component 3 is installed inside the first mounting frame 1 and is used to crush impurities in the wastewater. The crushing component 3 can rotate. The driving component 2 is installed on the side of the first mounting frame 1 and on the crushing component 3. The driving component 2 is used to drive the crushing component 3 to rotate in opposite directions. Two flow guiding structures 4 are fixed to the upper and lower sides inside the first mounting frame 1. The first side plate 5 is hinged inside the first mounting frame 1. The flow guiding structure 4 is a frame composed of two inverted V-shapes used to guide the wastewater and the crushed impurities in the wastewater. The locking component 6 is installed on the first mounting frame 1 to lock and limit the first side plate 5. It also includes a solid-liquid separation mechanism 7 and an auxiliary buffer mechanism 8. The solid-liquid separation mechanism 7 is used to divert the crushed impurities in the wastewater. The auxiliary buffer mechanism 8 buffers the solid-liquid separation mechanism 7 during screening.

[0027] In this embodiment, specifically, the solid-liquid separation mechanism 7 includes a second mounting frame 71, a motor 72, a turntable 73, a contact member 74, a guide member 75, a support plate 76, a first damper 77, a first spring 78, a second side plate 79, and a separation frame 710. The second mounting frame 71 is fixedly connected to the inside of the first mounting frame 1. The motor 72 is fixedly connected to the side of the second mounting frame 71 by bolts. The turntable 73 is fixedly connected to the output shaft of the motor 72. The turntable 73 has a protruding round rod on its side. The guide member 75 is fixedly connected to the second mounting frame 71. The contact member 74 is slidably connected to the guide member 75. The middle part of the contact member 74 is a frame. The protruding round rod on the turntable 73 is located in the frame in the middle of the contact member 74. The turntable 73 rotates... The contact member 74 moves laterally. Several first dampers 77 are symmetrically slidably connected to the second mounting frame 71. Symmetrically arranged support plates 76 are connected to the inner side of the first dampers 77. Symmetrically arranged first springs 78 are connected between the outer side of the support plate 76 and the inner side of the second mounting frame 71. The second side plate 79 is hinged to the side of the second mounting frame 71. The separation frame 710 is placed between the support plates 76. The bottom of the separation frame 710 is triangular prism-shaped to divert sewage and impurities and prevent accumulation. The lateral movement of the contact member 74 pushes the separation frame 710 to move. Under the action of the first springs 78, the separation frame 710 shakes, thereby screening and separating sewage and broken impurities. Furthermore, the auxiliary buffer mechanism 8 includes a mounting base 81, a contact plate 82, a second damper 83, and a second spring 84. The second damper 83 is slidably connected to the mounting base 81, and the contact plate 82 is fixedly connected to the end of the second damper 83 for buffering during the shaking of the separation frame 710 to prevent the separation frame 710 from hitting the inner wall of the second mounting frame 71. The second spring 84 is connected between the contact plate 82 and the mounting base 81. There are four auxiliary buffer mechanisms 8, which are respectively fixed to the side of the second side plate 79 and the inner wall of the second mounting frame 71 through the mounting base 81.

[0028] When using the wastewater treatment device with crushing function, the wastewater to be treated is first introduced into the first mounting frame 1. The wastewater first comes into contact with two guide structures 4 fixed to the upper and lower sides of the first mounting frame 1. The guide structure 4 is a frame composed of two inverted V-shapes, which can guide the wastewater to flow precisely to the crushing component 3, while preventing the wastewater from spreading randomly inside the first mounting frame 1 and improving the wastewater transport efficiency.

[0029] Activate drive assembly 2, which is installed on the side of the first mounting frame 1 and on the crushing assembly 3. Drive the crushing assembly 3 to rotate in opposite directions. The rotating crushing assembly 3 can squeeze, cut and crush large impurities in the sewage into smaller particles, laying the foundation for subsequent solid-liquid separation and preventing large impurities from clogging the subsequent separation structure, thus ensuring a smooth sewage treatment process. If maintenance is required on the crushing assembly 3 or the interior of the first mounting frame 1, the locking assembly 6 installed on the first mounting frame 1 can be unlocked, and the first side plate 5 can be rotated around the hinge point to open the interior space of the first mounting frame 1. After maintenance, rotate the first side plate 5 in the opposite direction to lock it in place using the locking assembly 6. The operation is convenient.

[0030] The crushed wastewater and impurity mixture enters the solid-liquid separation mechanism 7 under the secondary guidance of the guide structure 4. The motor 72 of the solid-liquid separation mechanism 7 is started. The motor 72 is fixed to the side of the second mounting frame 71 by bolts. The output shaft of the motor 72 drives the fixed turntable 73 to rotate. The round rod protruding from the side of the turntable 73 is located in the frame of the contact member 74. As the turntable 73 rotates, the round rod pushes the contact member 74 to slide laterally along the guide member 75 fixed to the second mounting frame 71. When the contact element 74 moves laterally, it pushes the separation frame 710 placed between the support plates 76. Under this force, the separation frame 710 moves the support plates 76, causing the first spring 78, which connects the outer side of the support plate 76 to the inner side of the second mounting frame 71, to stretch or compress. Simultaneously, the first damper 77, symmetrically slidably connected within the second mounting frame 71, moves accordingly. When the contact element 74 moves in the opposite direction, the first spring 78 resets, causing the support plates 76 and the separation frame 710 to shake in opposite directions. This cycle continues, causing the separation frame 710 to shake continuously. The bottom of the separation frame 710 is triangular prism-shaped. During the shaking process, it can both divert sewage and impurities, preventing accumulation, and allow sewage to pass through through its own screening structure, while retaining broken impurities, achieving efficient solid-liquid separation and improving sewage treatment efficiency.

[0031] During the shaking of the separation frame 710, four auxiliary buffer mechanisms 8 are activated. The auxiliary buffer mechanisms 8 are fixed to the side of the second side plate 79 and the inner wall of the second mounting frame 71 via mounting bases 81. When the shaking amplitude of the separation frame 710 is large and it contacts the contact plate 82, the contact plate 82 pushes the fixed second damper 83 to slide along the mounting base 81. At the same time, the second spring 84 connected between the contact plate 82 and the mounting base 81 is compressed. Through the damping effect of the second damper 83 and the elastic buffering of the second spring 84, the impact force of the separation frame 710 is absorbed, preventing the separation frame 710 from directly hitting the inner wall of the second mounting frame 71 or the second side plate 79, reducing component wear, extending the service life of the device, and ensuring that the shaking of the separation frame 710 is stable and does not affect the solid-liquid separation efficiency.

[0032] If it is necessary to clean the impurities trapped inside the separation frame 710, the second side plate 79, which is hinged to the side of the second mounting frame 71, can be rotated to directly remove the separation frame 710 from between the support plates 76. After cleaning, it can be put back. The operation is convenient, reduces the labor intensity of manual cleaning, and ensures the continuous and stable operation of the device.

[0033] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the scope of the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
