Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, and in particular to a multi-stage sedimentation and separation device for chemical wastewater. Background Technology

[0002] Multistage sedimentation separation primarily utilizes gravity to cause suspended solids, pollutants, or different components with a specific gravity greater than water to gradually settle to the bottom in multiple sedimentation layers, thereby achieving separation and purification. This process is based on the differences in sedimentation rate and solubility of different particles in the solution.

[0003] The existing Chinese utility model patent with application number CN202221792297.6 relates to a multi-stage sedimentation wastewater treatment device, including spiral blades, rotating shaft, filter screen, collection bucket, collection funnel and elastic plate, which can reduce the labor intensity of workers and improve the use effect; it is convenient to remove impurities after wastewater filtration, saving time and effort and is highly efficient.

[0004] However, in actual use, the above-mentioned device collects and stores sediment through a collection tank. When it is necessary to clean the sediment, the wastewater in the equipment must be discharged before the collection tank can be disassembled. The above-mentioned device does not have the ability to output and clean the sediment during the wastewater treatment process. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-stage sedimentation and separation device for chemical wastewater. It provides space for sedimentation of pollutants in wastewater through a sedimentation structure, enables the device to output the sediment from the bottom of the device during the wastewater treatment process through an output device, and collects and sends out the sediment output from the output devices in multiple areas through a collection device. This reduces the difficulty of equipment maintenance, reduces the labor intensity of operators, and improves the practicality of the device.

[0006] This utility model discloses a multi-stage sedimentation and separation device for chemical wastewater; it includes a sedimentation structure, an output device, and a collection device. The output device is installed on the sedimentation structure, and the collection device is installed on the output device. The sedimentation structure provides space for the sedimentation of pollutants in the wastewater. The output device enables the device to output the sediment from the bottom of the device during the wastewater treatment process. The collection device collects and sends out the sediment from the output devices in multiple areas, reducing the difficulty of equipment maintenance, reducing the labor intensity of operators, and improving the practicality of the device.

[0007] Preferably, the sedimentation structure includes a main tank, a grading tank, a sludge storage hopper, and filter plates. The main tank contains multiple grading tanks, and multiple filter plates are installed on the partitions between the multiple grading tanks. A sludge storage hopper is installed at the bottom of the grading tank. The filter plates filter the impurities in the wastewater, enabling the wastewater to undergo grading and sedimentation. The grading tanks provide space for the sedimentation process, and the sludge storage hoppers temporarily store the sediment, thus improving the practicality of the device.

[0008] Preferably, the device also includes a support frame, a first vibration motor, a support plate, and a connecting plate. Multiple sets of support frames are installed on the upper surface of the main tank, and these support frames are located on the upper side of the partition between two adjacent sub-tanks. The first vibration motor is installed on the support frame, and a set of connecting plates is connected to the left and right sides of the lower end face of the support frame. The support plate is installed on the partition, and the lower part of the connecting plate is connected to the middle part of the support plate. The support plate provides auxiliary support to the middle part of the filter plate. The first vibration motor is turned on periodically to transmit power to the support plate through the connecting plate, causing the support plate to vibrate, thereby shaking off the debris adhering to the filter plate, maintaining the working performance of the filter plate, and improving the practicality of the device.

[0009] Preferably, the output device includes a sludge discharge pipe, a first spiral blade, a first geared motor, and a bearing support. The bottom of the sludge storage hopper is inclinedly connected to the sludge discharge pipe, and the first geared motor is installed on the lower end face of the sludge discharge pipe. The output end of the first geared motor extends into the sludge discharge pipe and connects to the first spiral blade. The upper part of the first spiral blade extends into the bottom of the sludge storage hopper and connects to the inner side of the sludge storage hopper through the bearing support. When a large amount of sediment accumulates in the sludge storage hopper, the first geared motor is turned on to transmit power to the first spiral blade, which drives the first spiral blade to rotate. The rotating first spiral blade outputs the sediment in the sludge storage hopper, and the rotation speed of the first spiral blade is controlled to reduce the impact of sludge transportation on the turbidity of the sewage in the grading tank, thereby improving the practicality of the device.

[0010] Preferably, it also includes a weld overlay guide slope, with a weld overlay guide slope provided at the bottom of the sludge storage hopper, one side of which is inclined toward the side of the connected sludge discharge pipe; the weld overlay guide slope provided at the bottom of the sludge storage hopper reduces the situation where sediment accumulates in the corners of the bottom of the sludge storage hopper and cannot be discharged, thus improving the practicality of the device.

[0011] Preferably, the collection device includes a collection pipe, a base, a second spiral blade, a first plate-type solenoid valve, a second geared motor, and a second plate-type solenoid valve. The base is installed on the lower end face of the collection pipe, and the second geared motor is installed on the right end face of the collection pipe. The output end of the second geared motor extends into the collection pipe and connects to the second spiral blade. The second plate-type solenoid valve is installed on the left end face of the base. A discharge port is provided on the lower side of the sludge discharge pipe, and the discharge port is connected to the inside of the collection pipe through the first plate-type solenoid valve. The first plate-type solenoid valve is opened periodically to cooperate with the output device to send the sediment into the collection pipe. The sediment output from the output device on the multi-group grading tank is collected through the collection pipe and discharged through a unified port, which facilitates the operator's treatment of the sediment. The second geared motor is turned on to transmit power to the second spiral blade, which drives the second spiral blade to rotate and cooperates with the second plate-type solenoid valve to send out the sludge, thus improving the practicality of the device.

[0012] Preferably, it also includes a second vibration motor, which is installed on the lower side of the sludge hopper; turning on the second vibration motor transmits power to the sludge hopper to make it vibrate, thereby reducing the amount of sediment adhering to the inner side of the sludge hopper during the discharge of sediment in the grading tank, reducing sediment residue, and improving the practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the sedimentation structure provides space for the sedimentation of pollutants in sewage; the output device enables the equipment to output the sediment at the bottom of the equipment during the sewage treatment process; and the collection device collects and sends out the sediment output from the output devices in multiple areas, thereby reducing the difficulty of equipment maintenance, reducing the labor intensity of operators, and improving the practicality of the device.
