Description

Technical Field

[0001] This utility model relates to the field of concrete material testing, and in particular to a washing device for testing the mud content of aggregates. Background Technology

[0002] The mud content of aggregates refers to the proportion of impurities such as mud, sand, and dust contained in aggregates during the concrete preparation process. These impurities include dust, silt, and clay with a particle size of less than 0.08 mm.

[0003] In related technologies, the washing procedure for testing the mud content of aggregates typically involves placing the aggregate in a beaker, adding water, and thoroughly stirring the aggregate with a stirring rod. After standing for 2 hours, the upper turbid liquid in the beaker is poured out. During this process, the turbid liquid is filtered through a sieve to prevent aggregate from spilling out of the beaker. Subsequently, the aggregate on the sieve is returned to the beaker, water is added again, and the above steps are repeated until the upper liquid in the beaker is clear, thus completing the washing procedure.

[0004] However, during the process of recycling the aggregate from the sieve back into the beaker, the sieve is difficult to clean completely, and some aggregate will inevitably be missed, thus affecting the accuracy of the experiment, which needs to be improved. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a washing device for testing the mud content of aggregates, which can reduce the risk of aggregate loss and thus improve the accuracy of the test.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a washing device for testing the mud content of aggregates, including a washing beaker, wherein a filter screen is detachably connected inside the washing beaker, and the circumferential sidewall of the filter screen is in close contact with the inner sidewall of the washing beaker.

[0007] In a preferred embodiment, the present invention can be further configured such that: the inner wall of the washing beaker is provided with a stepped surface, and the bottom edge of the filter screen can abut against the stepped surface to limit the position of the filter screen.

[0008] In a preferred embodiment, the present invention can be further configured such that: a plurality of elastic limiting posts are fixedly connected at equal intervals along the circumference of the bottom of the filter screen, the diameter of the limiting posts gradually decreases from the middle to both ends, a plurality of limiting grooves are provided on the stepped surface, the inner sidewall of the limiting groove fits with the outer sidewall of the limiting post, and the plurality of limiting posts can be respectively inserted into the corresponding limiting groove.

[0009] In a preferred embodiment, the present invention can be further configured such that a lifting ring is fixedly connected to the filter screen.

[0010] In a preferred embodiment, the present invention can be further configured such that: the filter screen includes a support frame and a screen surface, the screen surface is fixed inside the support frame, the support frame is made of an elastic material, and the circumferential sidewall of the support frame can tightly abut against the inner sidewall of the washing beaker.

[0011] In a preferred embodiment, the present invention can be further configured such that the screen surface is made of stainless steel.

[0012] In a preferred embodiment, the present invention can be further configured such that the upper and lower surfaces of the screen surface are flush with the corresponding surfaces of the support frame.

[0013] In summary, this utility model has at least the following beneficial effects: The turbid liquid is filtered by a filter screen built into the washing beaker. At the same time, the filter screen can also keep the aggregate inside the washing beaker. When the tester adds water to the beaker, the aggregate can return to the bottom of the filter beaker with the water flow, effectively reducing the risk of aggregate loss and thus improving the accuracy of the test.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] Reference Figure 1 , Figure 2 A washing device for testing the mud content of aggregates includes a washing beaker 1, a filter screen 2 detachably connected inside the washing beaker 1, and the circumferential sidewall of the filter screen 2 tightly abutting against the inner sidewall of the washing beaker 1 to achieve filtration of turbid liquid and blocking of aggregates.

[0018] The turbid liquid is filtered by the filter screen built into the washing beaker 1. At the same time, the filter screen 2 can also block the aggregate in the washing beaker 1. When the tester adds water to the beaker, the aggregate can return to the bottom of the filter beaker with the water flow, effectively reducing the risk of aggregate loss and thus improving the accuracy of the test.

[0019] Reference Figure 2 , Figure 3 The inner wall of the washing beaker 1 is integrally formed with a stepped surface 3, and the bottom edge of the filter screen 2 can abut against the stepped surface 3 to limit the vertical downward direction of the filter screen 2. At the same time, a lifting ring 4 is fixedly connected to the filter screen 2 so that the test personnel can lift the filter screen 2.

[0020] Reference Figure 2 , Figure 3 The bottom of the filter screen 2 is fixedly connected with multiple elastic limiting posts 5 at equal intervals along its circumference. The diameter of the limiting posts 5 gradually decreases from the middle to both ends. Multiple limiting grooves 6 are provided on the stepped surface 3. The inner sidewall of the limiting groove 6 fits with the outer sidewall of the limiting post 5, and the multiple limiting posts 5 can be respectively inserted into the corresponding limiting groove 6.

[0021] Reference Figure 2 , Figure 3 The filter screen 2 includes a support frame 21 and a screen surface 22. The screen surface 22 is fixed inside the support frame 21 and is made of stainless steel, which improves both the rust resistance and durability of the filter screen 2. The support frame 21 is made of elastic material, and its circumferential sidewalls can tightly abut against the inner sidewall of the washing beaker 1 to improve the sealing effect between the filter screen 2 and the washing beaker 1 and reduce the risk of material leakage.

[0022] Reference Figure 2 , Figure 3 The upper surface of the screen surface 22 is flush with the upper surface of the support frame 21, and the lower surface of the screen surface 22 is flush with the lower surface of the support frame 21, so as to prevent the aggregate from depositing or getting stuck between the screen surface 22 and the support frame 21, thereby improving the stability of use.
