Description

Technical Field

[0001] The invention relates to a wastewater multi-stage treatment device, in particular to a packaging paper production wastewater multi-stage treatment device applied to the packaging paper production technology field. Background Art

[0002] Wrapping paper refers to paper used to package goods and materials. It usually has high physical strength, low moisture content, low air permeability and certain water resistance. According to its use, it can be divided into ordinary wrapping paper, food wrapping paper, oil-proof paper, moisture-proof paper, etc. In the production process of wrapping paper, a large amount of wastewater that needs to be treated is generated.

[0003] The invention patent with publication number CN118420013B discloses a wastewater treatment device for packaging paper bag production. The invention utilizes the bactericidal effect of paper ash to sterilize the wastewater, thereby saving the amount of bactericide used when the next-level purification system further purifies the wastewater.

[0004] The invention patent with publication number CN104445802B discloses a multi-stage sedimentation treatment system for papermaking wastewater. In the invention, the wastewater undergoes more than one biological sedimentation or fiber filtration, and finally undergoes a flocculation sedimentation to meet the reuse water standard and can be transported to the workshop for use as reuse water.

[0005] When treating wastewater from packaging paper production, the first step is usually to pre-treat the wastewater through a pre-treatment unit. The main purpose of pre-treatment is to remove suspended matter, adjust water quality and quantity, etc. When the raw water (untreated wastewater) is transported to the pre-treatment unit through the raw water pipeline, the suspended matter has not been removed, which leads to the easy generation of sediments on the inner wall of the pipeline. The sediments not only affect the wastewater treatment efficiency, but also easily lead to the deterioration of water quality and increased difficulty in treatment. Therefore, when the sediments in the pipeline accumulate to a certain amount, it is necessary to clean the sediments in the pipeline in time. However, the wastewater multi-stage treatment devices in the prior art generally lack the corresponding automatic sediment detection mechanism, making it difficult to accurately grasp the cleaning time, which easily leads to untimely sediment cleaning. Therefore, we propose a multi-stage treatment device for wastewater from packaging paper production. Summary of the invention

[0021] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0022] The first implementation method: Figure 1-Figure 6 A multi-stage treatment device for packaging paper production wastewater is shown, comprising a pretreatment unit, a biological treatment unit, and a deep treatment unit connected in sequence, and also comprising an intelligent inspection unit. The pretreatment unit comprises a coagulation sedimentation tank, the biological treatment unit comprises a contact oxidation tank, and the deep treatment unit comprises a membrane bioreactor. The intelligent inspection unit comprises a diversion inspection component installed at the end of a raw water pipeline, and the diversion inspection component comprises a transfer box 101. The bottom end of the transfer box 101 is connected with an outlet pipe 102, and the end of the outlet pipe 102 away from the transfer box 101 faces the coagulation sedimentation tank. The side wall of the transfer box 101 is connected with an inlet pipe 103, and the end of the inlet pipe 103 away from the transfer box 101 is connected to the raw water pipeline. An electromagnetic valve is arranged on the inlet pipe 103, and a lifting electric push rod 104 is fixedly installed on the inner wall of the top end of the transfer box 101. The output end of the lifting electric push rod 104 is fixedly connected with a valve matching the outlet pipe 102. A top sealing pipe plug 105 is provided, a support frame 106 is fixedly installed on the outer wall of the transfer box 101 away from the inlet connecting pipe 103, a push-pull electric push rod 107 is fixedly installed on the support frame 106, and the output end of the push-pull electric push rod 107 is fixedly connected to a bottom sealing plate 108 matching the outlet connecting pipe 102, the top end of the bottom sealing plate 108 is flush with the bottom end of the outlet connecting pipe 102, and an air guide pipe 109 is embedded through the bottom sealing plate 108, and the air guide pipe 109 The bottom end is connected to an air cylinder 110, and a controlled charging magnet 111 is fixedly installed on the inner wall of the bottom end of the air cylinder 110. An air piston plate 112 is provided above the controlled charging magnet 111 and is slidingly and sealingly connected to the inner wall of the air cylinder 110. The bottom end of the air piston plate 112 is fixedly connected to a linkage magnet 113, and a limit ring 114 is fixedly installed above the air piston plate 112, and an air pressure sensor 115 is fixedly installed above the limit ring 114.

[0023] The intelligent inspection unit also includes an inspection intelligent control system, which includes an inspection setting module, an inspection control module, an inspection analysis module, and a remote reminder module. The inspection setting module is signal-connected to the inspection control module, the inspection control module is signal-connected to the lifting electric push rod 104, the control charging magnet 111, the air pressure sensor 115, and the solenoid valve, the air pressure sensor 115 is signal-connected to the inspection analysis module, and the inspection analysis module is signal-connected to the remote reminder module.

[0024] When treating packaging paper production wastewater, the raw water is sequentially transported to the pretreatment unit through the raw water pipeline, the inlet connecting pipe 103, the transfer connecting box 101, and the outlet connecting pipe 102. The pretreatment unit pretreats the raw water, and then the biological treatment unit further treats the pretreated wastewater. Finally, the deep treatment unit deeply treats the wastewater. The material of the outlet connecting pipe 102 is the same as that of the raw water pipeline. Since the raw water is also transported through the outlet connecting pipe 102, sediments will also be generated on the inner wall of the outlet connecting pipe 102. Therefore, the sediment accumulation in the raw water pipeline can be indirectly detected by detecting the sediment accumulation in the outlet connecting pipe 102. According to the actual situation, the detection cycle and the reference air pressure threshold are reasonably set through the detection and accumulation setting module. The detection and accumulation intelligent control system will regularly control the execution of the operation of detecting the sediment accumulation in the outlet connecting pipe 102 according to the monitoring cycle; During the inspection, the storage control module will first close the solenoid valve to stop the delivery of raw water, and then the storage control module will control the lifting electric push rod 104 to drive the top sealing plug 105 to move downward until the top sealing plug 105 is inserted into the outlet connecting pipe 102 to block and seal the top of the outlet connecting pipe 102. At the same time, the storage control module will control the push-pull electric push rod 107 to push the bottom sealing plate 108 until the bottom sealing plate 108 moves to the outlet connecting pipe 102 to block and seal the bottom end of the outlet connecting pipe 102. Then the storage control module will control the charging control The magnet 111 is energized, so that the charging magnet 111 applies a magnetic repulsion force to the linkage magnet 113. Under the action of the magnetic repulsion force, the gas-filled piston plate 112 moves upward until the gas-filled piston plate 112 abuts against the limit ring 114. The upward movement of the gas-filled piston plate 112 squeezes the air above it, causing the air above it to enter the inner side of the outlet connecting pipe 102 through the air guide pipe 109, thereby increasing the air pressure inside the outlet connecting pipe 102. Then, the inspection control module starts the air pressure sensor 115, so that the air pressure sensor 115 detects The air pressure data detected by the air pressure sensor 115 will be transmitted to the inspection and accumulation analysis module. The amount of sediment in the outlet pipe 102 will affect the final air pressure data. The more sediment, the greater the final air pressure data. Therefore, the accumulation of sediment can be determined by analyzing the air pressure data detected by the air pressure sensor 115. The inspection and accumulation analysis module will compare the air pressure data detected by the air pressure sensor 115 with the reference air pressure threshold. If the air pressure data is greater than the reference air pressure data, it means that a large amount of sediment has accumulated in the outlet pipe 102. If cleaning is required, at this time, the inspection and analysis module will control the remote reminder module to send reminder information to relevant personnel (the reminder method can be to send text messages, emails, etc., and remote reminders are existing technologies and will not be described in detail here). After the detection is completed, the inspection and control module will control the charging magnet 111 to cut off the power to make the inflatable piston plate 112 move downward and reset, and control the push-pull electric push rod 107 to pull the bottom sealing plate 108 to reset, control the lifting electric push rod 104 to pull the top sealing pipe plug 105 to reset, and close the air pressure sensor 115 and open the solenoid valve; Therefore, through the setting of the intelligent inspection unit, the intelligent inspection unit can automatically detect the accumulation of sediments in the connecting pipe 102, and then indirectly detect the accumulation of sediments in the raw water pipeline. When the sediment accumulation reaches a threshold, it can automatically send a reminder to the relevant personnel, prompting the relevant personnel to clean the pipeline in time, which can effectively avoid the problems of reduced wastewater treatment efficiency, deterioration of water quality, and increased treatment difficulty caused by untimely sediment cleaning.

[0025] The inspection and accumulation intelligent control system also includes a compensation calculation module. The inspection and accumulation setting module is signal-connected to the compensation calculation module, and the compensation calculation module is signal-connected to the inspection and accumulation analysis module. A temperature sensor 120 is also fixedly installed in the inflator 110. The inspection and accumulation control module is signal-connected to the temperature sensor 120, and the temperature sensor 120 is signal-connected to the compensation calculation module. When the reference air pressure threshold is set through the inspection and accumulation setting module, a reference temperature corresponding to the reference air pressure threshold needs to be set. During detection, when the inspection and accumulation control module starts the air pressure sensor 115, the temperature sensor 120 will also be started (after the detection is completed, the inspection and accumulation control module will also turn off the temperature sensor 120 when turning off the air pressure sensor 115). The temperature sensor 120 is used to detect the temperature, and the detected temperature data will be transmitted to the compensation calculation module. The compensation calculation module will perform temperature compensation calculation on the reference air pressure threshold according to the temperature data detected by the temperature sensor 120, and calculate the reference air pressure threshold at the current temperature (the compensation calculation module is based on the ideal gas state equation Calculate the reference pressure threshold at the current temperature, where: is the reference pressure threshold at the current temperature, is the preset reference pressure threshold, is the reference temperature, The current temperature is the current temperature), and the calculation result is sent to the inspection and accumulation analysis module. When the inspection and accumulation analysis module analyzes and judges, it will analyze and judge according to the reference air pressure threshold at the current temperature calculated by the compensation calculation module, thereby eliminating the influence of temperature on the detection result and improving the accuracy of the detection result.

[0026] A pair of elastic pull ropes 116 are fixedly connected between the bottom end of the inflation piston plate 112 and the inner wall of the bottom end of the inflation cylinder 110. The elastic pull ropes 116 are conducive to the resetting of the inflation piston plate 112. A matching sealing baffle 117 is fixedly installed in the transfer box 101. The top sealing pipe plug 105 passes through the sealing baffle 117 and is slidably and sealedly connected thereto, and the bottom end of the top sealing pipe plug 105 is flush with the bottom end of the sealing baffle 117. The sealing baffle 117 can prevent the side wall of the top sealing pipe plug 105 from generating sediment, thereby ensuring the sealing effect of the top sealing pipe plug 105 on the top of the outlet pipe 102.

[0027] The outlet connecting pipe 102 and the inlet connecting pipe 103 both penetrate the outer wall of the transfer box 101 and are slidably and sealedly connected to the outer wall of the transfer box 101. The outer side of the outlet connecting pipe 102 is sleeved with a lower connecting seat 118, and the outer side of the inlet connecting pipe 103 is sleeved with a side connecting seat 119. The lower connecting seat 118 and the side connecting seat 119 are both fixedly connected to the transfer box 101, and the outlet connecting pipe 102 is threadedly connected to the lower connecting seat 118, and the inlet connecting pipe 103 is threadedly connected to the side connecting seat 119, so that the lower connecting seat 118 and the side connecting seat 119 are easy to disassemble, and then it is easy to clean the sediment in the lower connecting seat 118 and the side connecting seat 119.

[0028] The second implementation method: Figure 7-10 The figure shows a multi-stage treatment device for packaging paper production wastewater. Different from the first embodiment, a spacer ring 201 is provided on the inner side of the top of the outlet connecting pipe 102, which is slidably and sealedly connected thereto. The bottom end of the spacer ring 201 is fixedly connected to an annular scraper 202 matching the outlet connecting pipe 102. A connecting rope 203 is fixedly connected between the spacer ring 201 and the top sealing pipe plug 105. Since sediments may adhere to the inner wall of the outlet connecting pipe 102, during the detection process, the top sealing pipe plug 105 is inserted into the outlet. When the top sealing plug 105 is inserted into the connecting tube 102, the sediment may hinder the insertion of the top sealing plug 105 and affect the sealing effect of the top sealing plug 105. To avoid this phenomenon, in this embodiment, a spacer ring 201 and an annular scraper 202 are provided. The spacer ring 201 can prevent the inner wall at the top of the connecting tube 102 from generating sediment. During the detection process, when the top sealing plug 105 is inserted into the connecting tube 102, the spacer ring 201 will be pushed downward. At the position where the placeholder ring 201 was originally located, since there is no sediment here, the sealing effect of the top sealing plug 105 can be guaranteed. In the process of the top sealing plug 105 and the placeholder ring 201 moving downward, if they encounter obstacles of sediment, the annular scraper 202 will break the obstacles of the sediment, and ensure that the top sealing plug 105 can move downward smoothly, thereby ensuring that the top sealing plug 105 can be smoothly inserted into the outlet connecting tube 102. Therefore, through the setting of the placeholder ring 201, the annular scraper 202, etc., it is possible to prevent the sediment on the inner wall of the outlet connecting tube 102 from affecting the detection, and ensure that the top sealing plug 105 can be smoothly inserted into the outlet connecting tube 102 and effectively seal the top of the outlet connecting tube 102, thereby further improving the accuracy of the detection results. In addition, during the detection, since the annular scraper 202 may scrape off a small amount of sediment, the influence of this factor needs to be considered when setting the reference air pressure threshold, and the reference air pressure threshold is appropriately adjusted to eliminate the influence of this factor on the detection results.

[0029] A connecting ring 204 that matches the air guide tube 109 is provided on the inner side of the top end thereof, and an intercepting net 205 that matches the air guide tube 109 is fixedly connected to the bottom end thereof. During the detection process, a small amount of sediment may fall downwards, and the intercepting net 205 can prevent the sediment from falling into the inflation cylinder 110. The connecting ring 204 is threadedly connected to the air guide tube 109, and the intercepting net 205 is movably connected to the air guide tube 109. A screw rod 206 is fixedly installed on the inner side of the connecting ring 204, so that the connecting ring 204 can be rotated by the screw rod 206, so as to take out the connecting ring 204 and the intercepting net 205, thereby facilitating the cleaning of the sediment inside the connecting ring 204.

[0030] A cleaning brush 207 is provided on the side of the outlet pipe 102 away from the bottom sealing plate 108. The cleaning brush 207 is fixedly connected to the outlet pipe 102 by a connecting rod 208. The bottom end of the cleaning brush 207 and the top end of the bottom sealing plate 108 are at matching heights. During the detection process, a small amount of sediment may also fall onto the bottom sealing plate 108. Therefore, after the detection is completed, before the inspection and accumulation control module controls the push-pull electric push rod 107 to pull the bottom sealing plate 108 to reset, the inspection and accumulation control module will first control the push-pull electric push rod 107 to push the bottom sealing plate 108 again, so that the bottom sealing plate 108 moves toward the cleaning brush 207, so as to clean the sediment dropped on the bottom sealing plate 108 by the cleaning brush 207, so as to avoid the sediment on the bottom sealing plate 108 affecting the subsequent detection, thereby further improving the accuracy of the detection.

[0031] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
