Description

Technical Field

[0001] The utility model relates to the technical field of solid waste treatment, in particular to a solid waste treatment device based on rainwater collection. Background Art

[0002] With the continuous development and progress of society, people's environmental awareness has been continuously strengthened, and the actions for resource recycling have also increased. For example, rainwater can be collected and reused for irrigation of crops to save water resources. As far as the current rainwater collection device is concerned, in the process of rainwater collection, it is inevitable that solid waste will be mixed in the water and enter the rainwater mixing device, causing solid waste to enter the farmland at the same time during irrigation, affecting the impact of the farmland and the growth of crops.

[0003] In response to the above defects, the Chinese invention patent with patent number 202210811802.5 discloses a solid waste treatment device that uses a gear structure to crush solids and dehydrate them to separate solid waste and rainwater. Although it is possible to avoid the situation where solid waste is also irrigated in farmland when watering crops, there is still the problem of only physically crushing and dehydrating solid waste. If the solid waste contains toxic or radioactive substances, even if the solid waste is crushed and dehydrated, the rainwater is already mixed with toxic or radioactive substances, and irrigating it into the farmland will cause immeasurable damage to the crops and the geology of the farmland. Utility Model Content

[0004] The utility model aims to provide a solid waste treatment device based on rainwater collection, which can achieve solid-liquid separation and disinfect the liquid at the same time, thereby improving the safety of recycled rainwater reuse.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a solid waste treatment device based on rainwater collection, and the specific implementation scheme is as follows:

[0006] A solid waste treatment device based on rainwater collection, comprising a rainwater collection box, a rainwater collection platform is provided on the top of the rainwater collection box, a guide pipe is provided inside the rainwater collection box, and an inlet of the guide pipe is connected to the rainwater collection platform;

[0007] A solid waste conveying pipe is connected to the outlet of the guide pipe, and a retractable blocking component is provided between the guide pipe and the solid waste conveying pipe to control the conduction or cutoff of the solid waste conveying pipe and the guide pipe;

[0008] A rainwater delivery pipe is also connected to the outlet of the guide pipe, a first filter is provided between the guide pipe and the rainwater delivery pipe, a rainwater purification box is connected to the other end of the rainwater delivery pipe, a sterilization component and a stirring component are provided in the rainwater purification box, a rainwater recovery pipe is connected to the bottom of the rainwater purification box, and the rainwater recovery pipe extends outside the rainwater collection box.

[0009] The utility model is a solid waste treatment device based on rainwater collection. Compared with the prior art, a guide pipe is arranged inside a rainwater collection box, a rainwater delivery pipe and a solid waste delivery pipe are connected to the guide pipe, and a rainwater purification box is connected by the rainwater delivery pipe. A stirring component and a sterilizing component are arranged in the rainwater purification box. In actual use, on the one hand, rainwater enters the guide pipe inside the rainwater collection box through the rainwater collection table, and solid waste is blocked in the guide pipe after being filtered by a first filter screen between the guide pipe and the rainwater delivery pipe. Rainwater passes through the first filter screen and the rainwater delivery pipe and enters the guide pipe. After entering the rainwater purification box, the sterilization component is sterilized under the stirring and mixing of the stirring component to remove harmful substances, radioactive substances and bacteria in the rainwater as much as possible, thereby reducing the risk of rainwater mixed with toxic substances or radioactive substances being irrigated into farmland and causing immeasurable damage to crops and farmland geology; on the other hand, after the rainwater completely enters the rainwater purification box, the blocking component is opened to allow the solid waste blocked in the guide pipe to fall into the solid waste conveying pipe, thereby realizing the solid-liquid separation of rainwater and solid waste, so as to facilitate the subsequent transportation and treatment of the solid waste.

[0010] In some embodiments, the blocking assembly includes a blocking cylinder, which is fixed on the outer wall of the guide pipe.

When the rainwater completely enters the rainwater purification box, the drop opening is opened through the operation of the blocking component to allow the solid waste to fall into the solid waste conveying pipe, ensuring that the solid-liquid separation effect can be completely achieved between the solid waste and rainwater.

[0012] In some embodiments, the guide pipe is arranged to be inclined from top to bottom from the rainwater collection platform to the rainwater delivery pipe box, and a water volume sensor is provided at a position of the rainwater delivery pipe close to the first filter, and the water volume sensor is electrically connected to the blocking cylinder.

[0017] By arranging a driving rod with a crushing roller in the solid waste conveying pipe, the teeth on the two crushing rollers crush the solid waste after the solid waste enters the solid waste conveying pipe, thereby improving the convenience of subsequent transportation, compaction and degradation of the solid waste.

[0018] In some embodiments, a pull-out solid waste collection box is provided at the bottom of the rainwater collection box, the top of the solid waste collection box is open and is located below the solid waste conveying pipe, and the bottom of the solid waste collection box is inclined from top to bottom from close to the solid waste conveying pipe to away from the solid waste conveying pipe.

[0019] By arranging a pull-out solid waste collection box at the bottom of the solid waste conveying pipeline, the convenience of removing solid waste is improved, and the bottom of the solid waste collection box is arranged to be inclined so that the solid waste can be guided to the bottom after falling into the solid waste collection box to avoid accumulation under the solid waste conveying pipeline, thereby increasing the storage capacity of the solid waste collection box.

[0020] In some of the embodiments, the sterilization component includes a fixed light panel fixed on the top wall of the rainwater purification box, and a plurality of ultraviolet sterilization lamps are arranged on the fixed light panel.

[0021] By adopting a structure in which a number of ultraviolet sterilization lamps are arranged on a fixed lamp panel, the rainwater entering the rainwater purification box is irradiated with ultraviolet rays, thereby achieving the purpose of sterilizing and disinfecting the rainwater and removing harmful substances and radioactive substances to the greatest extent.

[0022] In some embodiments, the stirring assembly includes a rotating shaft mounted in the rainwater purification box, a plurality of stirring paddles are provided on the outer wall of the rotating shaft, and one end of the rotating shaft extends outside the rainwater collection box and is transmission-connected to a stirring motor fixed in the rainwater collection box.

[0023] The stirring motor drives the rotating shaft to rotate and drives the stirring paddle to stir the rainwater in the rainwater purification box, thereby improving the irradiation uniformity of the ultraviolet sterilization lamp of the rainwater sterilization component, thereby improving the sterilization and purification effect of the rainwater.

[0024] In some of the embodiments, a control valve and a water pump are provided on the rainwater recovery pipe, the control valve is used to control the opening and closing of the rainwater recovery pipe, and the water pump is used to transport the rainwater in the rainwater purification box to the outside.

[0025] By installing control valves and water pumps on rainwater recycling pipes, the convenience and controllability of rainwater recycling can be improved.

[0026] In some embodiments, a control panel is embedded in the outer wall of the rainwater collection box, the control panel is electrically connected to a control circuit board, the control circuit board is electrically connected to the blocking component, the stirring component and the sterilization component, and a start-stop button, a first indicator light and a second indicator light are provided on the rainwater collection box, and the start-stop button, the first indicator light and the second indicator light are electrically connected to the control circuit board.

[0027] By embedding a control panel connected to a control circuit board in the rainwater collection box, the basic information of the device is displayed on the control panel, and the working parameters of the blocking component, the stirring component and the sterilization component are set and adjusted through the control panel, so as to further improve the controllability of the device.

The rainwater passes through the first filter and the rainwater delivery pipe and enters the rainwater purification box. Under the stirring and mixing of the stirring component, the sterilization component is sterilized to remove harmful substances, radioactive substances and bacteria in the rainwater as much as possible, thereby reducing the risk of inestimable damage to crops and the geology of the farmland caused by toxic substances or radioactive substances mixed in the rainwater; on the other hand, after the rainwater completely enters the rainwater purification box, the blocking component is opened to make the solid waste blocked in the guide pipe fall into the solid waste delivery pipe, so as to achieve solid-liquid separation of rainwater and solid waste, so as to facilitate the subsequent transportation and treatment of the solid waste.
