Description

Technical Field

[0001] This utility model relates to the field of septic tank cleaning equipment, specifically a septic tank bottom impurity cleaning device. Background Technology

[0002] Bar screens are key equipment for cleaning impurities at the bottom of septic tanks. Through their mechanical structure, they effectively separate large impurities such as paper and plastic bags from sewage. If these impurities accumulate at the bottom of the septic tank for a long time, they will not only affect the treatment efficiency of the septic tank, but may also cause problems such as pipe blockage and equipment damage. Bar screens, through their unique mechanical structure, can effectively separate these impurities from sewage, ensuring the smooth operation of the septic tank.

[0003] A search revealed that, according to announcement number CN217511326U, "A Bar Screen Cleaner," the rake teeth are easily covered with garbage and impurities, and the self-cleaning effect of the bar screen cleaner is poor. The description states that as the rake teeth move with the bar screen belt, they contact a scraper. The scraper, supported by a support spring, further scrapes away the debris adhering to the rake teeth surface. Finally, the cleaned waste falls through a chute into a waste collection bin for collection. However, during implementation, the support springs need to bounce repeatedly, which can easily lead to aging. Sometimes, feces or sewage splash onto the support springs, which may cause them to rust, affecting the cleaning effect. Furthermore, the scraper's adaptive scraping action on the rake teeth reduces the continuity of operation, thus reducing the ease of use of the bar screen cleaner. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a septic tank bottom impurity cleaning device to solve the technical problem that garbage and impurities easily adhere to the rake teeth and the cleaning result is poor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a septic tank bottom impurity cleaning device, comprising a septic tank, a cleaning device installed inside the septic tank, a motor housing installed on one side of the cleaning device, a conveyor belt installed inside the cleaning device, multiple sets of rake teeth installed on the surface of the conveyor belt, a cleaning roller installed on one side of the conveyor belt, multiple sets of spikes installed on the surface of the cleaning roller, a driven wheel installed at one end of the cleaning roller, a driving wheel installed at one end of the conveyor belt, and a belt sleeved on the outer side of the driving wheel and the driven wheel.

[0006] By adopting the above technical solution, the cleaning equipment is first adjusted to the working angle to ensure that the impurities in the septic tank can be effectively scooped up by the rake teeth and smoothly transported to the discharge port. Then, the control center starts the motor box, and the output end of the motor box starts to drive the drive shaft on the conveyor belt to rotate. As the drive shaft rotates, the rake teeth begin to move in the septic tank to scoop up the impurities at the bottom of the tank. At the same time, the rotation of the drive shaft also drives the rotation of the drive wheel. The drive wheel is driven by the driven wheel through the belt, thereby realizing the synchronous rotation of the conveyor belt and the cleaning roller. Since the rake teeth and the spiked teeth are staggered on the conveyor belt and the cleaning roller, when the rake teeth scoop up the impurities and pass through the cleaning roller, the spiked teeth will scrape off and clean the garbage wrapped or attached to the rake teeth.

[0007] Furthermore, the multiple sets of rake teeth are arranged at equal intervals along the outer periphery of the conveyor belt, and the multiple sets of spiked teeth are arranged in an equal-interval ring along the outer periphery of the cleaning roller.

[0008] By adopting the above technical solution, it is ensured that the rake teeth can evenly remove impurities from the bottom of the septic tank, avoiding blind spots caused by uneven distribution of the rake teeth.

[0009] Furthermore, each group of spiked teeth and rake teeth is provided with multiple spiked teeth, which are conical in shape and are staggered with the rake teeth.

[0010] By adopting the above technical solution, the contact area between the spikes and the rakes is increased, making the cleaning more thorough.

[0011] Furthermore, the top of the cleaning device is provided with multiple water inlets, each of which is equipped with a water inlet pipe, and each of the water inlet pipes is threaded with a top cover.

[0012] By adopting the above technical solution, it is possible to easily introduce external water sources into the equipment for rinsing.

[0013] Furthermore, the cleaning device is tilted as a whole, and a filter plate is provided on one side of the bottom of the conveyor belt.

[0014] By adopting the above technical solution, impurities can be more easily moved towards the discharge port under the action of gravity, thus improving cleaning efficiency.

[0015] Furthermore, an observation door is provided on one side of the top of the cleaning device, and two sets of handles are provided on one side of the observation door.

[0016] By adopting the above technical solution, staff can easily observe the internal operation of the equipment and the cleaning effect.

[0017] Furthermore, a discharge port is provided on one side of the bottom of the cleaning device, and a collection bin is provided below the discharge port.

[0018] By adopting the above technical solution, the cleaned impurities can be easily discharged outside the equipment.

[0019] Furthermore, the motor housing is electrically connected to an external power source via a control center, and the output end of the motor housing is connected to the drive roller of the conveyor belt.

[0020] By adopting the above technical solution, it is ensured that the motor box can stably receive power from the external power source.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. This utility model uses a cleaning roller to first adjust the cleaning equipment to a suitable working angle, ensuring that impurities can be effectively scooped up by the rake teeth and smoothly transported. Then, the control center starts the motor box, and the motor output drives the transmission shaft on the conveyor belt to rotate, thereby driving the rake teeth to move in the septic tank to scoop up impurities. At the same time, the rotation of the transmission shaft also drives the rotation of the drive wheel. The drive wheel is connected to the driven wheel through a belt, realizing the synchronous rotation of the conveyor belt and the cleaning roller. Because the rake teeth and the spiked teeth are arranged alternately, when the rake teeth scoop up impurities and pass through the cleaning roller, the spiked teeth will scrape off the garbage wrapped or attached to the rake teeth. This process not only reduces the accumulation of garbage on the rake teeth, avoiding the impact of excessive garbage on the cleaning effect of the septic tank, but also reduces the residue of dirt on the rake teeth, making the use of the bar screen cleaner more convenient and improving its cleanliness.

[0023] 2. This utility model, by setting up a water inlet pipe and a top cover, allows external water sources to be conveniently introduced into the cleaning equipment, providing the necessary rinsing water source for the equipment. During the cleaning process, injecting clean water into the equipment through the water inlet pipe can effectively wash away residual dirt and impurities on the rake teeth and conveyor belt, improving the cleanliness and cleaning efficiency of the equipment.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] Example 1:

[0031] A septic tank bottom impurity cleaning device, such as Figures 1-4 As shown, the system includes a septic tank 1, a cleaning device 2 inside the septic tank 1, a motor housing 3 on one side of the cleaning device 2, a conveyor belt 13 inside the cleaning device 2, multiple sets of rake teeth 14 on the surface of the conveyor belt 13, a washing roller 15 on one side of the conveyor belt 13, multiple sets of spikes 16 on the surface of the washing roller 15, a driven wheel 12 at one end of the washing roller 15, and a driving wheel 10 at one end of the conveyor belt 13. A belt 11 is fitted around the driving wheel 10 and the driven wheel 12. First, the cleaning device 2 is adjusted to its working angle to ensure that impurities in the septic tank 1 can be effectively scooped up by the rake teeth 14 and smoothly transported to the discharge port 7. Then, the control center starts the motor housing 3, and the output end of the motor housing 3 begins to drive the drive shaft on the conveyor belt 13. As the drive shaft rotates, the rake teeth 14 begin to move within the septic tank 1, scooping up impurities from the bottom of the tank. Simultaneously, the rotation of the drive shaft also drives the rotation of the drive wheel 10, which is transmitted to the driven wheel 12 via the belt 11, thus achieving synchronous rotation of the conveyor belt 13 and the cleaning roller 15. Since the rake teeth 14 and the spiked teeth 16 are staggered on the conveyor belt 13 and the cleaning roller 15, when the rake teeth 14 scoop up impurities and pass through the cleaning roller 15, the spiked teeth 16 scrape off and clean the garbage entangled or adhered to the rake teeth 14. This not only reduces the accumulation of garbage on the rake teeth 14, effectively preventing excessive garbage from hindering the cleaning of the septic tank 1, but also greatly reduces the amount of residual sludge on the rake teeth 14, thereby ensuring the long-term stable operation of the septic tank 1.

[0032] See Figure 3 , Figure 4Multiple sets of rake teeth 14 are arranged at equal intervals along the outer periphery of the conveyor belt 13, and multiple sets of spiked teeth 16 are arranged at equal intervals in a ring along the outer periphery of the cleaning roller 15. This ensures that the rake teeth 14 can evenly remove impurities from the bottom of the septic tank 1, avoiding blind spots caused by uneven distribution of the rake teeth 14. At the same time, the arrangement of multiple sets of spiked teeth 16 in a ring along the outer periphery of the cleaning roller 15 allows the spiked teeth 16 to fully contact the rake teeth 14, thoroughly scraping away the garbage wrapped or attached to the rake teeth 14, thereby improving the cleaning efficiency and effect of the cleaning equipment 2.

[0033] See Figure 3 , Figure 4 Each set of spiked teeth and rake teeth 14 is equipped with multiple spiked teeth 16. The spiked teeth 16 have a pointed conical structure and are staggered with the rake teeth 14, which increases the contact area between the spiked teeth 16 and the rake teeth 14, making the cleaning more thorough. At the same time, the pointed conical structure of the spiked teeth 16 makes it easier for the spiked teeth to penetrate and scrape off stubborn dirt on the rake teeth 14. In addition, the staggered arrangement of the spiked teeth 16 and the rake teeth 14 not only enhances the self-cleaning ability of the cleaning device 2, but also avoids interference between the spiked teeth 16 and the rake teeth 14, ensuring the stable operation of the equipment.

[0034] Example 2:

[0035] See Figure 1 , Figure 2 , Figure 3 The cleaning device 2 has multiple water inlets on its top, and each water inlet is equipped with a water inlet pipe 8. Each water inlet pipe 8 is threaded with a top cover 9. This allows external water to be easily introduced into the device for rinsing. At the same time, the threaded connection of the top cover 9 to the outside of the water inlet pipe 8 not only facilitates the installation and disassembly of the water inlet pipe 8, but also ensures the sealing of the device during operation, preventing the infiltration of sewage and impurities. Through regular rinsing, the cleanliness and service life of the cleaning device 2 can be further improved.

[0036] See Figure 1 , Figure 2 , Figure 3 The cleaning device 2 is set at an angle. A filter plate 17 is set on one side of the bottom of the conveyor belt 13, which makes it easier for impurities to move towards the discharge port 7 under the action of gravity, thus improving the cleaning efficiency. At the same time, the filter plate 17 on one side of the bottom of the conveyor belt 13 can block large particles of impurities from entering the equipment, protecting key components such as the conveyor belt 13 and the cleaning roller 15 from damage, and ensuring the long-term stable operation of the equipment.

[0037] See Figure 1 , Figure 2 , Figure 3An observation door 4 is provided on one side of the top of the cleaning device 2. Two sets of handles 5 are provided on one side of the observation door 4, which allows the staff to easily observe the operation and cleaning effect inside the equipment. At the same time, the two sets of handles 5 on one side of the observation door 4 not only facilitate the opening and closing of the observation door 4, but also improve the safety of the staff during operation. With the cooperation of the observation door 4 and the handles 5, the staff can more conveniently maintain and repair the equipment.

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The cleaning device 2 has a discharge port 7 on one side below the bottom. A collection bin 6 is set below the discharge port 7, which allows the cleaned impurities to be easily discharged outside the device. At the same time, the collection bin 6 can collect and store the cleaned impurities, which facilitates subsequent transportation and processing. Through the cooperation of the discharge port 7 and the collection bin 6, the impurities are quickly cleaned and effectively processed, which improves the practicality and convenience of the cleaning device 2.

[0039] See Figure 1 , Figure 2 , Figure 3 The motor housing 3 is electrically connected to an external power source through the control center. The output end of the motor housing 3 is connected to the drive roller of the conveyor belt 13, ensuring that the motor housing 3 can stably receive power from the external power source. At the same time, the output end of the motor housing 3 is connected to the drive roller of the conveyor belt 13. This connection method allows the motor housing 3 to directly drive the conveyor belt 13 to operate. Through the cooperation of the motor housing 3 and the control center, the automated control and efficient operation of the cleaning equipment 2 are realized, improving the stability and reliability of the equipment.

[0040] The implementation principle of this utility model is as follows: First, the cleaning device 2 is adjusted to a suitable angle, and then the control center controls the motor box 3 to operate, thereby enabling the output end to drive the transmission shaft on the conveyor belt 13 to rotate, so that the rake teeth 14 can scoop up the impurities in the septic tank 1. When the transmission shaft rotates, the transmission shaft drives the drive wheel 10 to rotate, and the drive wheel 10 drives the driven wheel 12 to rotate through the belt 11, thereby enabling the conveyor belt 13 and the cleaning roller 15 to rotate synchronously. Because the rake teeth 14 and the spiked teeth 16 are staggered, the spiked teeth 16 will clean the garbage wrapped around the rake teeth 14. In this process, due to the presence of the spiked teeth 16, not only is the amount of garbage adhering to or wrapped around the rake teeth 14 of the bar screen cleaner reduced, which affects the cleaning effect of the septic tank, but the residue of dirt on the rake teeth 14 is also reduced, thereby improving the ease of use and cleanliness of the bar screen cleaner.

[0041] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
