Abstract
Description
Technical Field
[0001] This utility model belongs to the field of screening device technology, and in particular relates to a membrane element screening device. Background Technology
[0002] With the diversification of the water treatment field, various membrane element manufacturers have designed numerous membrane element series for different application scenarios. The operating conditions and pollutant rejection capabilities of different series of membrane elements vary greatly. Even within the same series of membrane elements, different models have different operating conditions and pollutant rejection capabilities. When mass-producing membrane elements, it is necessary to screen or classify various performance aspects of the membrane elements to select superior, medium, or defective products. However, existing screening devices are generally used for screening granular materials.
[0003] For example, patent document with publication number "CN216261929U" discloses a screening device for powdered raw materials for ceramic membrane elements, including a box, a feed pipe, a mounting plate, a rotating frame, a first connecting shaft, a screen frame, two sets of connecting seats, two sets of pistons, two sets of cylinders, two sets of second connecting shafts, a material bucket, a guide pipe, a feeding barrel, a spiral feeding roller, a motor, and a discharge pipe. The output end of the feed pipe passes through the top of the box and extends into the inside of the box. The feeding barrel is installed on the right side of the bottom of the box. The spiral feeding roller is rotatably installed inside the feeding barrel. The motor is installed on the left end of the feeding barrel, and the output end of the motor is connected to the left end of the spiral feeding roller. The input end of the discharge pipe passes through the lower right end of the box and communicates with the feeding barrel. A receiving device is provided inside the box. This patented technology can automatically collect and dump large, unqualified powdery raw materials remaining on the screen frame, saving labor, simplifying operation, and improving work efficiency. However, existing screening equipment often only performs a "two-choice" process for granular materials, treating materials that pass through the screen holes as one type and those that fail as another. In multi-stage progressive screening devices, each "two-choice" screening requires testing relevant characteristic parameters of the material for differentiation. However, for cylindrical materials like membrane elements, even with similar shapes, the performance parameters of membrane elements can vary significantly. Therefore, existing screening equipment is not suitable for membrane elements. Furthermore, if membrane elements need to be screened into multiple varieties, multiple "two-choice" screenings need to be connected in series, obviously increasing equipment costs and hindering the improvement of screening efficiency. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a membrane element screening device.
[0005] This utility model is achieved through the following technical solution.
[0006] This utility model provides a membrane element screening device, including a controller, a collector, a main material channel and several sub-material channels. One end of each sub-material channel is connected to one end of the main material channel, and the other end of each sub-material channel extends outward. Each sub-material channel is hinged to a baffle at the connection between it and the main material channel. Each baffle is also hinged to the output shaft of an actuator. The control end of the actuator and the collector are electrically connected to the controller.
[0007] Data collector: The data collector is used to collect the characteristic parameters of the membrane element and forward the characteristic parameters to the controller;
[0008] Controller: The controller is used to issue control commands to each actuator. The control commands include the status information of each material distribution channel. The controller also stores several element thresholds. Each element threshold corresponds one-to-one with the status information of each material distribution channel. Along the material movement direction in the main material channel, the element thresholds are arranged in ascending order. The controller is also used to compare the characteristic parameters from the collector with each element threshold. If the element threshold is greater than the characteristic parameter, the status information of the material distribution channel corresponding to the element threshold is set to "blocked", and the status information of the other material distribution channels is set to "open".
[0009] Actuator: The actuator is used to receive control commands from the controller and receive corresponding status information from the control commands. If the status information is "blocked", the actuator drives the baffle to block the corresponding material distribution channel. If the status information is "open", the actuator drives the baffle to block the main material channel.
[0010] A material collection frame is also provided at the end of the material distribution channel.
[0011] The number of material distribution channels is two or more.
[0012] The actuator is a cylinder.
[0013] The characteristic parameters include the pressure resistance of the membrane element.
[0014] The main material channel has a bend, and the branch material channel is connected to the bend of the main material channel.
[0015] The main material channel is composed of several unit material channels connected end to end, and the bends of the main material channel are formed by the connection between two adjacent unit material channels.
[0016] The left and right sides of the baffle are also fixedly connected to the protective wings.
[0017] The membrane element screening device also includes a frame, on which the controller, collector, main feed channel and distribution channel are all mounted.
[0018] The frame is constructed using aluminum profiles.
[0019] The beneficial effects of this utility model are as follows: Using the technical solution of this utility model, before the membrane element is fed into the main feed channel, the characteristic parameters of the membrane element are first acquired by the collector and forwarded to the controller. The controller then issues control commands to each actuator, including the status information of each feed channel. The controller also stores several element thresholds, each element threshold corresponding one-to-one with the status information of each feed channel. The controller also compares the characteristic parameters from the collector with each element threshold. If an element threshold is greater than the characteristic parameter, the status information of the feed channel corresponding to that element threshold is set to "blocked," and the status information of the other feed channels is set to "open." The actuator receives control commands from the controller and corresponding status information within the control commands. If the status information is "blocked," the actuator drives the baffle to block the corresponding material distribution channel. If the status information is "open," the actuator drives the baffle to block the main material channel. After the membrane element enters the main material channel, the membrane element rolls into the corresponding material distribution channel according to the path selected by the controller. Membrane elements that meet the corresponding classification are directly obtained from the end of each material distribution channel. Compared with the prior art, this utility model enables the screening equipment to be applicable to cylindrical materials such as membrane elements, and it is equipped with only one collector, eliminating the two-choice screening method, simplifying the equipment structure, and reducing the equipment cost.

[0023] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.
[0024] like Figures 1 to 2 As shown, this utility model provides a membrane element screening device, including a controller 1, a collector 2, a main material channel 3 and several distribution channels 4. One end of the distribution channel 4 is connected to one end of the main material channel 3, and the other end of the distribution channel 4 extends outward. Each distribution channel 4 is hinged to a baffle 5 at the connection between it and the main material channel 3. Each baffle 5 is also hinged to the output shaft of an actuator 6. The control end of the actuator 6 and the collector 2 are electrically connected to the controller 1, respectively.
[0025] Data Collector 2: Data Collector 2 is used to collect the characteristic parameters of the membrane element and forward these characteristic parameters to Controller 1;
[0026] Controller 1: Controller 1 is used to issue control commands to each actuator 6. The control commands include the status information of each material distribution channel 4. Controller 1 also stores several element thresholds. Each element threshold corresponds one-to-one with the status information of each material distribution channel 4. Along the material movement direction in the main material channel 3, the element thresholds are arranged in ascending order. Controller 1 is also used to compare the characteristic parameters from the collector 2 with each element threshold. If the element threshold is greater than the characteristic parameter, the status information of the material distribution channel 4 corresponding to the element threshold is set to "blocked", and the status information of the other material distribution channels 4 is set to "open".
[0027] Actuator 6: Actuator 6 is used to receive control commands from controller 1 and receive corresponding status information from the control commands. If the status information is "blocked", actuator 6 drives baffle 5 to block the corresponding material channel 4. If the status information is "open", actuator 6 drives baffle 5 to block the main material channel 3.
[0028] Using the technical solution of this utility model, before the membrane element is put into the main feed channel, the characteristic parameters of the membrane element are first acquired by the collector and forwarded to the controller. The controller then issues control commands to each actuator. The control commands include the status information of each feed channel. The controller also stores several element thresholds, each element threshold corresponding one-to-one with the status information of each feed channel. The controller is also used to compare the characteristic parameters from the collector with each element threshold. If an element threshold is greater than the characteristic parameter, the status information of the feed channel corresponding to that element threshold is set to "blocked," and the status information of the other feed channels is set to "open." The actuators then... The actuator receives control commands from the controller and corresponding status information within the control commands. If the status information is "blocked", the actuator drives the baffle to block the corresponding material distribution channel. If the status information is "open", the actuator drives the baffle to block the main material channel. After the membrane element enters the main material channel, the membrane element rolls into the corresponding material distribution channel according to the path selected by the controller. Membrane elements that meet the corresponding classification are directly obtained from the end of each material distribution channel. Compared with the prior art, this utility model enables the screening equipment to be applicable to cylindrical materials such as membrane elements, and it is equipped with only one collector, eliminating the two-choice screening method, simplifying the equipment structure and reducing the equipment cost.
[0029] Specifically, a material collection frame 7 is also provided at the end of the distribution channel 4. There are two or more distribution channels 4. The actuator 6 is a cylinder. Characteristic parameters include the pressure resistance of the membrane element. The main channel 3 has a bend, and the distribution channels 4 are connected to the bend of the main channel 3. The main channel 3 is composed of several unit channels connected end-to-end, and the bend of the main channel 3 is formed by the connection between two adjacent unit channels. The left and right sides of the baffle 5 are also fixedly connected to the protective wings 8.
[0030] For example, when membrane elements need to be screened into three types: superior, medium, and substandard, the characteristic parameters of the membrane elements are selected based on the pressure resistance of the membrane elements and the number of feed channels is two. The corresponding element thresholds are 10MPa and 20MPa, respectively. When a membrane element with a characteristic parameter of 15MPa enters the main feed channel, the first feed channel is blocked because the first element threshold is greater than the characteristic parameter and the second element threshold is less than the characteristic parameter. The second feed channel is open, allowing the membrane element to roll out through the main feed channel and the second feed channel. This membrane element can be classified as medium grade.
[0031] In addition, the membrane element screening device also includes a frame 9, on which the controller 1, collector 2, main feed channel 3, and distribution channel 4 are all mounted. The frame 9 is constructed of aluminum profiles.
