Description

Technical Field

[0001] The utility model relates to the technical field of water treatment membrane testing, in particular to a water treatment flat membrane wear resistance testing device. Background Art

[0002] Membrane separation technology has the functions of separation, concentration, purification and refinement, and is characterized by high efficiency, energy saving, environmental protection and easy control. It has been widely used in food, medicine and other fields, generating huge economic and social benefits and has become one of the most important means of separation technology today.

[0003] As the core component of membrane separation technology, flat membranes are often called the "chips" of water treatment membrane assemblies. Their quality determines the success of water treatment products. Therefore, quality testing of flat membranes is a top priority for water treatment product manufacturers.

[0004] Currently, quality testing for flat-plate diaphragms for water treatment primarily relies on basic performance testing. Once these tests are passed, on-site operation is used to assess the product's durability or robustness. This lack of pre-shipment durability and robustness testing increases the likelihood of product problems during field operation. Furthermore, there is currently no testing equipment or methods to perform pre-shipment durability and robustness testing on flat-plate diaphragms for water treatment. Utility Model Content

[0005] The purpose of the utility model is to design a wear resistance testing device for flat diaphragms for water treatment to address the shortcoming that the diaphragm products lack durability and toughness testing before leaving the factory, which easily increases the problems caused by the products during on-site operation. The testing device can carry out durability and toughness testing on flat diaphragms for water treatment before leaving the factory, thereby screening out unqualified products, greatly reducing the probability of problems caused by the products during on-site operation, and solving the above-mentioned problems.

[0006] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0007] The utility model designs a water treatment flat diaphragm wear resistance testing device, which includes:

[0008] Test device body;

[0009] a slide rail, which is provided on the testing device body;

[0010] a mechanical arm, which is slidably arranged on the slide rail;

[0011] A test platform, which is provided on the test device body and is used to place the water treatment flat membrane to be tested for wear resistance;

[0012] a control panel, which is provided on the testing device body and is used to control the reciprocating sliding of the mechanical arm along the slide rail;

[0013] and a wear-resistance test module, which is detachably arranged on the mechanical arm and driven by the mechanical arm to achieve friction on the water treatment flat diaphragm placed on the test platform.

[0014] Specifically, the testing principle of the water treatment flat diaphragm wear resistance testing device designed in the present invention is as follows: the water treatment flat diaphragm is laid on the test platform, and then the wear resistance test module is placed on the water treatment flat diaphragm and connected to the robotic arm, and then the reciprocating speed and number of round trips of the robotic arm are set through the control panel. After the wear resistance test module is driven by the robotic arm to complete the friction test on the diaphragm, the water treatment flat diaphragm on the test platform is subjected to a standard test, and the test data after friction is analyzed to judge the wear resistance and durability of the water treatment flat diaphragm.

[0015] Furthermore, a water treatment flat diaphragm wear resistance testing device: the wear resistance testing module is provided with a connecting portion, and the wear resistance testing module can be flexibly hung on the robotic arm through the connecting portion.

[0016] Furthermore, a water treatment flat diaphragm wear resistance testing device is provided: wear resistance test modules of different weights can be selected according to different wear resistance test requirements of the diaphragm. The higher the wear resistance requirement of the diaphragm, the heavier the weight of the selected wear resistance test module.

[0017] Furthermore, a water treatment flat diaphragm wear resistance testing device is provided: the wear resistance testing module is provided with a mesh structure on the friction surface with the diaphragm.

[0018] Specifically, the mesh structure is provided on a side of the wear-resistant test module opposite to the connecting portion.

[0019] Beneficial effects of the utility model:

[0020] (1) The wear resistance testing device for water treatment flat diaphragms designed in the present invention can test the durability and toughness of water treatment flat diaphragm products before they leave the factory, thereby greatly reducing the problems that may arise during the on-site operation of the products.

[0022] (3) Wear resistance test variable test: The wear resistance test device for water treatment flat diaphragms designed in this utility model can perform multivariate testing and evaluation of the wear resistance of the same water treatment flat diaphragm by adjusting the weight, speed, number of round trips and other conditions of the wear resistance test module.
