Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly filter presses, and in particular to an adjustable flow rate environmentally friendly filter press feed inlet structure. Background Technology

[0002] An environmentally friendly filter press is a solid-liquid separation device designed specifically to reduce environmental impact. Compared to traditional filter presses, it has been optimized and improved in terms of energy saving, emission reduction and resource recycling.

[0003] The adjustable flow rate environmentally friendly filter press feed inlet structure is a feeding device for filter presses. It can precisely adjust the flow rate of the material entering the filter press according to the working status of the filter press and the characteristics of the material, so as to achieve an efficient and environmentally friendly solid-liquid separation process.

[0004] The existing adjustable flow rate environmentally friendly filter press inlet structure has the following shortcomings:

[0005] In the operation of a filter press, the feed inlet structure is a key aspect of material feeding. The feed inlet structure of the traditional filter press frame has obvious defects. Due to the lack of a pushing mechanism, solid-liquid mixtures are very likely to remain in the feed pipe. These residual materials will be mixed into the new raw materials when processing different products in the future. Even tiny residues can interfere with the composition and characteristics of the new materials, affect the filtration effect, and lead to a decrease in product purity and quality, or even cause quality failure. Utility Model Content

[0006] The scraper of this invention adheres to the inner wall of the feed pipe, and with the continuous rotation of the rotating rod, it can efficiently scrape off the solid-liquid mixture remaining on the pipe wall, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable flow rate environmentally friendly filter press inlet structure, comprising an integral mechanism, the outer wall of which is provided with facility components; the integral mechanism includes a fixed disc and a first connecting pipe, the top of which is fixedly connected to a feed pipe, a sealing ring is slidably connected to the outer wall of the first connecting pipe, a disc is fixedly connected to the outer wall of the sealing ring, a servo motor is fixedly installed on the outer wall of the disc, a connecting rod is fixedly connected to the output end of the servo motor, a set of scrapers is fixedly connected to the outer wall of the connecting rod, and threaded blades are fixedly connected to the outer wall of the connecting rod. Through the above components, the solid-liquid mixture adhering to the pipe wall can be continuously scraped off, effectively reducing material residue and avoiding cross-contamination between different batches of raw materials.

[0008] Preferably, a sealing cap is movably inserted into the inner wall of the feed pipe, and a handle is fixedly connected to the top of the sealing cap. The outer wall of the sealing ring is slidably connected to the inner wall of the first connecting pipe. By setting the sealing cap, it is possible to prevent foreign objects from falling into the first connecting pipe through the feed pipe when not in use.

[0009] Preferably, an electric regulating valve is fixedly connected to the outer wall of the fixed plate, and a second connecting pipe is fixedly connected to the outer wall of the electric regulating valve. The second connecting pipe is connected to the inner wall of the first connecting pipe. By using the electric regulating valve, the opening degree of the valve can be precisely controlled by driving the motor.

[0010] Preferably, an electromagnetic flow sensor is fixedly installed on the outer wall of the second connecting pipe, and an electrode is fixedly installed on the outer wall of the electromagnetic flow sensor. Through the electromagnetic flow sensor and the electrode, the electrode comes into contact with the material in the pipe to accurately measure the flow rate of the material. The flow rate is continuously monitored and the new flow signal is fed back to the PLC controller.

[0011] Preferably, a set of first bolts is threaded through the outer wall of the disc, and a first threaded hole is provided on the outer wall of the disc. The inner wall of the first threaded hole is threadedly connected to the outer wall of the first bolt. The outer thread of the first bolt penetrates the inner wall of the first connecting pipe. The first bolt and the first threaded hole facilitate the user to connect the disc to the first connecting pipe, making it easy for the user to disassemble and assemble the disc for maintenance of the components on it.

[0012] Preferably, the outer wall of the fixed plate is threaded with a second bolt, and the outer wall of the scraper is slidably connected to the inner wall of the first connecting pipe. The second bolts facilitate the user to connect the entire mechanism to the press frame.

[0013] Preferably, the facility component includes a pressing frame, the outer wall of which has a feed hole, a PLC controller is fixedly installed on one side of the front of the pressing frame, and the outer wall of the pressing frame has a second threaded hole. The inner wall of the second threaded hole is threadedly connected to the outer wall of the second bolt. The PLC controller is electrically connected to the components to control the opening and closing of the components.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, when the solid-liquid mixture flows into the first connecting pipe through the feed pipe, the PLC controller drives the servo motor to operate. When the servo motor rotates, it drives the connecting rod to operate synchronously, thereby causing the threaded blades and scraper to rotate together. The scraper adheres to the inner wall of the feed pipe. With the continuous rotation of the rotating rod, the solid-liquid mixture remaining on the pipe wall can be efficiently scraped off, effectively avoiding cross-contamination between different batches of raw materials and significantly improving product quality. At the same time, the threaded blades generate axial thrust during rotation, pushing the solid-liquid mixture forward quickly, greatly enhancing the smoothness of conveying, reducing the risk of blockage, significantly improving the feeding efficiency of the filter press, and ensuring the efficient and stable operation of the equipment.

[0016] 2. In this utility model, the sealing ring at the connection between the disc and the first connecting pipe effectively enhances the sealing performance and prevents material leakage. The design of the first bolt and the first threaded hole facilitates quick disassembly and assembly of the disc by the user, improving maintenance convenience. In addition, the PLC controller, electrodes and electromagnetic flow sensor work together to monitor the flow rate in the first and second connecting pipes in real time and accurately. Once an abnormal flow rate is detected, the PLC controller can immediately control the electric regulating valve to automatically adjust the opening, thereby achieving precise control of the flow rate and ensuring the stable and efficient feeding process of the filter press.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Please see Figures 1-5 This utility model provides a technical solution: an adjustable flow rate environmentally friendly filter press inlet structure, including an integral mechanism 1, with a facility component 2 provided on the outer wall of the integral mechanism 1; the integral mechanism 1 includes a fixed disk 101 and a first connecting pipe 106, the top of the first connecting pipe 106 is fixedly connected to a feed pipe 107, a sealing ring 111 is slidably connected to the outer wall of the first connecting pipe 106, a disc 110 is fixedly connected to the outer wall of the sealing ring 111, a servo motor 116 is fixedly installed on the outer wall of the disc 110, a connecting rod 117 is fixedly connected to the output end of the servo motor 116, a set of scrapers 114 is fixedly connected to the outer wall of the connecting rod 117, and threaded blades 115 are fixedly connected to the outer wall of the connecting rod 117. Through the above components, the solid-liquid mixture adhering to the pipe wall can be continuously scraped off, effectively reducing material residue and avoiding cross-contamination between different batches of raw materials.

[0026] like Figure 2 As shown, a sealing cap 109 is movably inserted into the inner wall of the feed pipe 107. A handle 108 is fixedly connected to the top of the sealing cap 109. The outer wall of the sealing ring 111 is slidably connected to the inner wall of the first connecting pipe 106. By setting the sealing cap 109, it is possible to prevent foreign objects from falling into the first connecting pipe 106 through the feed pipe 107 when not in use.

[0027] like Figure 2As shown, an electric regulating valve 103 is fixedly connected to the outer wall of the fixed plate 101, and a second connecting pipe 104 is fixedly connected to the outer wall of the electric regulating valve 103. The second connecting pipe 104 is connected to the inner wall of the first connecting pipe 106. By using the electric regulating valve 103, the opening degree of the valve can be driven by the motor, and the flow rate can be precisely controlled.

[0028] like Figure 2 As shown, an electromagnetic flow sensor 105 is fixedly installed on the outer wall of the second connecting pipe 104. An electrode is fixedly installed on the outer wall of the electromagnetic flow sensor 105. Through the electromagnetic flow sensor 105 and the electrode, the electrode comes into contact with the material in the pipe to accurately measure the flow rate of the material. The flow rate is continuously monitored and the new flow signal is fed back to the PLC controller 204.

[0029] like Figure 2 As shown, a set of first bolts 113 are threaded through the outer wall of the disc 110. A first threaded hole 112 is opened on the outer wall of the disc 110. The inner wall of the first threaded hole 112 is threadedly connected to the outer wall of the first bolt 113. The outer wall thread of the first bolt 113 passes through the inner wall of the first connecting pipe 106. Through the first bolt 113 and the first threaded hole 112, it is convenient for the user to connect the disc 110 to the first connecting pipe 106, so that the user can disassemble and assemble the disc 110 for maintenance of its components.

[0030] like Figure 2 and Figure 3 As shown, the outer wall of the fixed plate 101 is threaded with second bolts 102, and the outer wall of the scraper 114 is slidably connected to the inner wall of the first connecting pipe 106. The second bolts 102 facilitate the user to connect the overall mechanism 1 to the pressing frame 201.

[0031] like Figure 5 As shown, the facility component 2 includes a pressing frame 201. The outer wall of the pressing frame 201 has a feed hole 203. A PLC controller 204 is fixedly installed on one side of the front of the pressing frame 201. The outer wall of the pressing frame 201 has a second threaded hole 202. The inner wall of the second threaded hole 202 is threadedly connected to the outer wall of the second bolt 102. The PLC controller 204 is electrically connected to the components to control the opening and closing of the components.

[0032] The operating method and working principle of this device are as follows: When the solid-liquid mixture slowly flows into the first connecting pipe 106 along the feed pipe 107, the user starts the servo motor 116 through the control panel on the PLC controller 204. After the servo motor 116 starts, its powerful output drives the connected rod 117 to rotate. The scraper 114 and threaded blade 115 on the connecting rod 117 rotate accordingly. The scraper 114 adheres to the inner wall of the feed pipe 107. During the continuous rotation of the scraper 114, it can efficiently scrape off the solid-liquid mixture adhering to the pipe wall, effectively avoiding cross-contamination between different batches of raw materials and improving product quality. When the threaded blade 115 rotates, it generates axial thrust. In the first connecting pipe 106, the threaded blade 115 pushes the material forward. After entering the second connecting pipe 104, it mainly flows under the action of pressure difference, etc., enhancing the smoothness of conveying, reducing the risk of blockage, and improving the feeding efficiency of the filter press. During the entire feeding process, the electromagnetic flow sensor 105 and its matching electrodes installed on the outer wall of the second connecting pipe 104 begin to play their role. The electrodes are directly connected to the pipe. The electromagnetic flow sensor 105, through contact with the internally flowing material and utilizing the principle of electromagnetic induction, can accurately measure the flow rate and continuously monitor real-time changes in flow. Subsequently, the electromagnetic flow sensor 105 quickly feeds back these newly acquired flow signals to the PLC controller 204. Upon receiving the flow signals from the electromagnetic flow sensor 105, the PLC controller 204 immediately initiates its internal data analysis and comparison program, meticulously comparing the actual flow value with the preset ideal flow value. If an abnormal flow rate is detected, it quickly issues a command to immediately control the electric regulating valve 103 to automatically adjust its opening. When the actual flow rate is higher than the preset value, the opening of the electric regulating valve 103 is precisely reduced, thereby reducing the amount of material conveyed. Conversely, when the actual flow rate is lower than the preset value, the opening of the electric regulating valve 103 is correspondingly increased to ensure that more material can pass through smoothly. Through this precise and timely adjustment mechanism, accurate control of the material flow rate entering the filter press is ultimately achieved, comprehensively ensuring that the filter press feeding process remains in a stable and efficient operating state.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
