Description

Technical Field

[0001] The utility model relates to the technical field of salt spray test chambers, in particular to an energy-saving water replenishing device for a salt spray test chamber. Background Art

[0002] The salt spray test chamber is a device used to test the salt spray corrosion resistance of materials and their protective layers. It simulates the salt spray environment to assess the corrosion resistance of materials and their protective layers to ensure the stability and reliability of the product in various environments. It tests the corrosion resistance of the tested samples through salt spray corrosion, simulates extreme conditions under natural conditions or working conditions, and understands the performance of each sample.

[0003] Patent number CN217332109U discloses a salt spray test chamber comprising: a chamber housing; a spray assembly disposed within the chamber, the spray assembly comprising a vertically arranged spray pipe and a plurality of atomizing nozzles disposed around the spray pipe; and a material rack disposed within the chamber surrounding the spray assembly. This utility model surrounds the spray assembly with the material rack, ensuring that products on the material rack come into full contact with the salt spray sprayed by the spray assembly. This ensures a uniform salt spray concentration across the product within the chamber, reducing test errors and time, thereby ensuring test efficiency.

[0004] The above-mentioned device has certain shortcomings when used: the material trays are stacked vertically on each other to realize the simultaneous salt spray test of multiple groups of products. However, during the experiment, the salt water solution on the surface of the product sample located at the top will drip onto other product samples located at the bottom, causing problems such as test data errors.

[0005] To this end, the utility model provides an energy-saving water replenishing device for a salt spray test chamber to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides an energy-saving water replenishing device for a salt spray test chamber, which solves the above problems.

The outer sides of the two L-shaped placement racks are in contact with the inner wall of the box. A number of U-shaped seats are evenly fixedly installed on the adjacent sides of the two L-shaped placement racks. The inner walls of the U-shaped seats located in the middle are rotatably mounted with inclined plates, and the sides of the bottom walls of the inclined plates that are away from each other are fixedly mounted with abutment seats. The inner walls of the U-shaped seats located at the top and bottom are rotatably mounted with placement racks, and the top walls of the placement racks are provided with placement grooves, and the bottom walls of the placement grooves are evenly provided with a number of drainage ports, and the sides of the bottom walls of the placement racks that are away from each other are fixedly mounted with abutment blocks;

[0010] Through the above technical solution, the placement component is set up, and during the test, the product to be tested can be placed on the inner wall of the placement groove on the top of the placement plate. When the salt mist comes into contact with the product, it condenses into beads and slides down and contacts the inclined plate and then slides into the box body without coming into contact with the product located below.

[0011] Furthermore, two L-shaped racks are provided with insertion openings on the tops, and several of the U-shaped seats are evenly arranged in the upper, middle and lower parts. The side walls of the abutment seats are all fitted with the inner walls of the corresponding L-shaped racks, and the side walls of the racks are provided with grooves. The side walls of the abutment blocks are all fitted with the inner walls of the corresponding L-shaped racks. Blocking bars are fixedly installed on the left and right sides of the bottom wall of the box body and at positions corresponding to the bottom of the L-shaped racks. The side walls of the blocking bars are all fitted with the outer walls of the corresponding L-shaped racks. The bottom wall of the liquid storage tank is fixedly connected to the inner bottom wall of the control cabinet, the bottom wall of the liquid storage tank is connected to the atomization assembly, the water inlet pipe is connected to the external salt spray liquid tank, and the liquid level meter and the liquid pump are electrically connected to the controller.

[0012] Through the above technical solution, the setting of the insertion opening is mainly convenient for taking and placing the L-shaped placement rack, and the blocking bar mainly serves to support and limit the L-shaped placement rack.

[0013] Furthermore, the atomization assembly includes an L-shaped connecting pipe, the right top of the L-shaped connecting pipe is connected to the bottom wall of the liquid storage tank, and the top of the L-shaped connecting pipe passes through the control cabinet, workbench and box body in sequence through a leak-proof rubber sleeve and is connected to a vertical pipe.

[0014] Through the above technical solution, the L-shaped connecting pipe is mainly used to transport the salt solution into the interior of the vertical pipe.

[0015] Furthermore, the vertical pipe is located in the middle of the inner cavity of the box, the outer wall of the vertical pipe is evenly connected to a plurality of spray heads, and a concentration sensor is installed on the inner rear wall of the box.

[0016] Through the above technical solution, the concentration sensor is mainly used to detect the salt spray concentration inside the box.

[0017] Furthermore, a cover plate is rotatably mounted on the top wall of the control cabinet, a transparent observation cover is hingedly mounted on the top wall of the box body, a sealing ring is fixedly mounted on the bottom wall of the transparent observation cover, a sealing groove is opened on the top wall of the box body, and the inner wall of the sealing groove is in contact with the outer wall of the sealing ring.

[0018] Through the above technical solution, the sealing groove and the sealing ring cooperate with each other, so as to increase the sealing performance between the transparent observation cover and the box body.

[0019] Furthermore, the rear wall of the box is connected to a drain pipe.

[0020] Through the above technical solution, the drain pipe is mainly used to discharge the salt solution collected on the bottom wall of the box.

[0021] Furthermore, support legs are fixedly installed at the four corners of the bottom wall of the workbench.

[0022] Through the above technical solution, the supporting legs have the function of supporting and fixing the entire device.

[0023] Beneficial effects

[0024] The utility model provides an energy-saving water replenishing device for a salt spray test chamber. Compared with the existing technology, it has the following beneficial effects:

[0025] (1) The energy-saving water replenishing device of the salt spray test chamber drives the placement plate and the inclined plate to be placed into the interior of the chamber and fit with the blocking strip through the L-shaped placement rack, flips the placement plate to drive the abutment block to fit with the inner wall of the L-shaped placement rack, rotates the inclined plate to drive the abutment seat to fit with the inner wall of the L-shaped placement rack, and the product is placed in the placement tank. When the liquid level of the storage tank drops to the liquid level gauge at the bottom, the liquid pump draws the solution from the outside through the water inlet pipe and enters the storage tank through the water outlet pipe until the liquid level reaches the liquid level gauge at the top. The liquid pump stops working, and the solution inside the storage tank enters the vertical pipe through the L-shaped connecting pipe and then sprays salt mist from the spray head to fill the chamber and contact the product surface for salt spray corrosion test. The salt spray concentration inside the chamber is detected by the concentration sensor, so that when conducting the salt spray corrosion resistance test, the products to be tested can be classified and placed first, and multiple batches of tests can be carried out at the same time. The salt solution on the sample surface will not drip onto the surface of other samples at the bottom, and when the salt solution is insufficient, water can be automatically replenished without additional manual intervention.
