Description
Technical Field
[0001] This application relates to the field of building energy conservation technology, specifically a concrete raw material quality inspection device. Background Technology
[0002] In the construction of various building projects, concrete, as a core building material, directly affects the safety and durability of the project. Therefore, comprehensive and rigorous quality testing of concrete raw materials is crucial. Concrete quality inspection can be divided into three main aspects: internal quality (compressive strength, flexural strength, frost resistance, impermeability, chloride ion penetration resistance, and steel reinforcement protective layer thickness, etc.), surface quality, and dimensional quality. When testing lime raw materials for concrete, the lime needs to be screened in multiple layers to determine the proportion of different particles within the raw material.
[0003] Currently, it is not possible to quickly weigh and calculate the weight of the material on multiple layers of filter paper during screening. The material on each layer of filter paper needs to be poured out and weighed separately, which reduces the efficiency of concrete raw material quality inspection. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a concrete raw material quality inspection device that can quickly weigh and calculate the weight of materials on multiple layers of filter paper without having to weigh each layer of material separately, thus improving the efficiency of concrete raw material quality inspection. This solves the problem that during screening, it is impossible to quickly weigh and calculate the weight of materials on multiple layers of filter paper, requiring each layer of material to be weighed separately, resulting in low efficiency in concrete raw material quality inspection.
[0005] To achieve the goal of quickly weighing and calculating the weight of materials on multiple layers of filter paper without having to weigh each layer of filter paper separately, thus improving the efficiency of concrete raw material quality inspection, this application provides the following technical solution: A concrete raw material quality inspection device, including a vibrating base, an installation frame on the top of the vibrating base, a collection box inserted into the inner wall of the middle of the installation frame, multiple screening cylinders stacked above the collection box, a first installation ring at the bottom of the inner wall of the middle of the screening cylinder, multiple first positioning pins arranged in a circular array at the bottom of the first installation ring, the outer surface of the middle of the first positioning pins being inserted into the inner wall of one side of a second installation ring, a fixing nut being threaded onto the outer surface of the middle of the first positioning pins, and filter paper being disposed between the first installation ring and the second installation ring.
[0006] A fixing frame is provided on the inner wall of the middle part of the screening cylinder. A gravity sensor is provided at the bottom of the middle part of the fixing frame through a fixing block. A connecting rope is connected to the bottom of the gravity sensor. A connecting rod is connected to one end of the connecting rope. A mounting base is connected to the bottom of the connecting rod. A second positioning pin is provided at the bottom of the mounting base. The outer surface of the middle part of the second positioning pin is inserted into the inner wall of the middle part of the filter paper. A threaded sleeve is threadedly connected to the outer surface of the middle part of the second positioning pin. A fixing ring is provided at the top of the threaded sleeve. The middle part of the filter paper is located between the fixing ring and the mounting base.
[0007] The above solution uses filter paper to filter materials. The weight of the material isolated on top of the filter paper is used to pull a gravity sensor via a connecting rod and rope. This allows the gravity sensor to weigh the material on top of the filter paper, enabling rapid weighing and calculation of materials on multiple layers of filter paper without having to weigh each layer individually. This improves the efficiency of concrete raw material quality inspection.
[0008] Furthermore, a first anti-slip pad and a second anti-slip pad are provided between the first mounting ring and the second mounting ring. The first anti-slip pad is located at the bottom of the first mounting ring, and the second anti-slip pad is located at the top of the second mounting ring.
[0009] The above solution uses the first anti-slip pad in conjunction with the second anti-slip pad to stably clamp the edge of the filter paper, preventing the filter paper from slipping off between the first mounting ring and the second mounting ring.
[0010] Furthermore, the outer surfaces on both sides of the fixing frame are inclined, and the inclined outer surfaces on both sides of the fixing frame are symmetrically arranged.
[0011] The above solution allows the material falling from the filter paper above to slide off the outer surface of the fixed frame by symmetrically arranged inclined outer surfaces on both sides of the fixed frame. This prevents material from accumulating on the fixed frame and affecting the falling of the material, thereby preventing any impact on the accuracy of the screening and quality inspection of concrete raw materials.
[0012] Furthermore, one end of the connecting rod is inserted into the inner wall of the middle part of the positioning tube, and the positioning tube is located at the bottom of the gravity sensor.
[0013] The above solution fixes the movement trajectory of the connecting rod by inserting it into the positioning tube, thus preventing the connecting rod from tilting and affecting the weighing of the material above the filter paper.
[0014] Furthermore, the mounting base is tapered, and the outer surface of the middle part of the mounting base is smooth.
[0015] The above solution allows the material falling onto the mounting base to slide back onto the filter paper for sieving through the conical design of the mounting base, thus preventing the mounting base from affecting the sieving of the material by the filter paper.
[0016] Furthermore, a material collection hopper is provided on the inner wall of the middle part of the screening cylinder. The material collection hopper is funnel-shaped, and the diameter of the discharge port at the bottom of the material collection hopper is smaller than the diameter of the inner wall of the middle part of the first mounting ring.
[0017] The above scheme guides the material falling from above by setting up the collection hopper, allowing the material to fall stably onto the filter paper and preventing it from falling onto the first mounting ring, which would affect the screening and weighing of the material.
[0018] Furthermore, the filter paper has positioning holes of the same number and specifications as the first positioning pins around its perimeter, and the positioning holes around the filter paper are fitted onto the outer surface of the middle part of the first positioning pin.
[0019] With the above solution, the positioning holes opened around the filter paper are fitted onto the first positioning pin, which can position the filter paper during installation, so that the second mounting ring can cooperate with the first mounting ring to stably clamp and fix the filter paper.
[0020] Furthermore, an inner positioning ring is provided at the top of the screening cylinder, and an outer positioning ring is provided at the bottom of the screening cylinder. The inner positioning ring and the outer positioning ring between two adjacent screening cylinders are sleeved on each other. The inner positioning ring at the top of the screening cylinder is inserted into the inner wall of the middle part of the top cover, and the outer positioning ring at the bottom of the screening cylinder is sleeved on the outer surface of the top of the collection box.
[0021] The above solution allows two screening cylinders to be stacked together by using an inner positioning ring in conjunction with an outer positioning ring. This improves the stability of the stacked cylinders and prevents them from separating due to vibration. It also ensures that the top cover is stably placed on the top of the screening cylinders, and the outer positioning ring at the bottom of the screening cylinders allows them to be stably placed on the collection box.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] This concrete raw material quality inspection device works by filtering the material through filter paper. The weight of the material isolated on top of the filter paper is used to pull a gravity sensor via a connecting rod and a connecting rope. This causes the gravity sensor to weigh the material on top of the filter paper, enabling rapid weighing and calculation of the material on multiple layers of filter paper without having to weigh the material on each layer separately. This improves the efficiency of concrete raw material quality inspection.
[0024] This concrete raw material quality inspection device generates vibration through the setting of the vibrating base, which in turn causes the filter paper to shake, assisting the filter paper in screening materials. The first positioning pin and the fixing nut can easily press and fix the edge of the filter paper and remove it. The threaded sleeve and the second positioning pin can easily press and fix the middle of the filter paper and remove it. Furthermore, the threaded sleeve and the second positioning pin allow the mounting base to clamp and fix the middle of the filter paper with the fixing ring, so that the weight on the filter paper can be stably transmitted to the gravity sensor through the connecting rod and the connecting rope.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] Please see Figure 1 , Figure 3 and Figure 4This embodiment of a concrete raw material quality inspection device includes a vibrating base 1, an installation frame 2 on the top of the vibrating base 1, a collection box 3 inserted into the inner wall of the middle of the installation frame 2, multiple screening cylinders 4 stacked on top of the collection box 3, a first installation ring 5 at the bottom of the inner wall of the middle of the screening cylinder 4, multiple first positioning pins 6 arranged in a circular array at the bottom of the first installation ring 5, the outer surface of the middle of the first positioning pin 6 inserted into the inner wall of one side of the second installation ring 7, a fixing nut 8 threadedly connected to the outer surface of the middle of the first positioning pin 6, and filter paper 9 provided between the first installation ring 5 and the second installation ring 7.
[0033] Please see Figure 2 , Figure 3 and Figure 4 A fixed frame 12 is provided on the inner wall of the middle part of the screening cylinder 4. A gravity sensor 13 is provided at the bottom of the middle part of the fixed frame 12 via a fixed block. A connecting rope 14 is connected to the bottom of the gravity sensor 13. A connecting rod 15 is connected to one end of the connecting rope 14. A mounting base 16 is connected to the bottom of the connecting rod 15. A second positioning pin 17 is provided at the bottom of the mounting base 16. The outer surface of the middle part of the second positioning pin 17 is inserted into the inner wall of the middle part of the filter paper 9. A threaded sleeve 19 is threadedly connected to the outer surface of the middle part of the second positioning pin 17. A fixing ring 18 is provided at the top of the threaded sleeve 19. The middle part of the filter paper 9 is located between the fixing ring 18 and the mounting base 16.
[0034] Please see Figure 2 , Figure 3 and Figure 4 A first anti-slip pad 10 and a second anti-slip pad 11 are provided between the first mounting ring 5 and the second mounting ring 7. The first anti-slip pad 10 is located at the bottom of the first mounting ring 5, and the second anti-slip pad 11 is located at the top of the second mounting ring 7. The first anti-slip pad 10 and the second anti-slip pad 11 can stably clamp the edge of the filter paper 9, preventing the filter paper 9 from slipping off between the first mounting ring 5 and the second mounting ring 7.
[0035] Please see Figure 2 , Figure 3 and Figure 4 The outer surfaces of the two sides of the fixing frame 12 are inclined and symmetrical. The inclined outer surfaces of the two sides of the fixing frame 12 are symmetrically arranged so that the material falling from the filter paper 9 above can slide off the outer surface of the fixing frame 12, avoiding the accumulation of material on the fixing frame 12 and affecting the falling of the material, thereby preventing the impact on the accuracy of the screening and quality inspection of concrete raw materials.
[0036] Please see Figure 2 , Figure 3 and Figure 4One end of the connecting rod 15 is inserted into the inner wall of the middle part of the positioning tube 24. The positioning tube 24 is located at the bottom of the gravity sensor 13. The connecting rod 15 is inserted into the inside of the positioning tube 24 to fix the movement trajectory of the connecting rod 15 and prevent the connecting rod 15 from tilting, which would affect the weighing of the material above the filter paper 9.
[0037] Please see Figure 2 , Figure 3 and Figure 4 The mounting base 16 is conical, and the outer surface of the middle part of the mounting base 16 is smooth. The conical shape of the mounting base 16 allows the material falling on the mounting base 16 to slide back onto the filter paper 9 for screening, thus avoiding the mounting base 16 affecting the screening of the material by the filter paper 9.
[0038] Please see Figure 2 , Figure 3 and Figure 4 A material collection hopper 23 is provided on the inner wall of the middle part of the screening cylinder 4. The material collection hopper 23 is funnel-shaped. The diameter of the discharge port at the bottom of the material collection hopper 23 is smaller than the diameter of the inner wall of the middle part of the first mounting ring 5. The material collection hopper 23 can guide the material falling from above, so that the material can fall stably onto the filter paper 9, and avoid the material falling onto the first mounting ring 5, which would affect the screening and weighing of the material.
[0039] Please see Figure 2 , Figure 3 and Figure 4 The filter paper 9 has positioning holes of the same number and specifications as the first positioning pin 6 around its perimeter. The positioning holes of the filter paper 9 are fitted onto the outer surface of the middle part of the first positioning pin 6. By fitting the filter paper 9 onto the first positioning pin 6 through the positioning holes of the filter paper 9 around its perimeter, the position of the filter paper 9 can be positioned when the filter paper 9 is installed, so that the second mounting ring 7 can cooperate with the first mounting ring 5 to stably clamp and fix the filter paper 9.
[0040] Please see Figure 2 , Figure 3 and Figure 4 The sieve cylinder 4 is provided with an inner positioning ring 20 at the top and an outer positioning ring 21 at the bottom. The inner positioning ring 20 and the outer positioning ring 21 between two adjacent sieve cylinders 4 are sleeved together. The inner positioning ring 20 at the top of the sieve cylinder 4 is inserted into the inner wall of the top cover 22. The outer positioning ring 21 at the bottom of the sieve cylinder 4 is sleeved on the outer surface of the top of the collection box 3. The inner positioning ring 20 and the outer positioning ring 21 can make the two sieve cylinders 4 stacked together, which can improve the stability of the two sieve cylinders 4 when stacked and avoid the two sieve cylinders 4 from falling apart due to vibration. It can also make the top cover 22 more stably cover the top of the sieve cylinder 4. The outer positioning ring 21 at the bottom of the sieve cylinder 4 can make the sieve cylinder 4 stably placed on the collection box 3.
[0041] In this embodiment, a concrete raw material quality inspection device is used. The material is filtered by filter paper 9. The weight of the material isolated on top of the filter paper 9 is pulled by the gravity sensor 13 through the connecting rod 15 and the connecting rope 14. The gravity sensor 13 weighs the material on top of the filter paper 9, which can quickly weigh and calculate the weight of the material on multiple layers of filter paper 9 without having to pour out the material on each layer of filter paper 9 for weighing separately, thus improving the efficiency of concrete raw material quality inspection.
[0042] It should be noted that the filter paper 9 is made of a soft material and has a redundancy in the middle, so that the middle of the filter paper 9 can be lowered by the weight of the material, thereby allowing the gravity sensor 13 to weigh the material above the filter paper 9.
[0043] The working principle of the above embodiment is as follows: The top cover 22 is removed from the uppermost screening cylinder 4. The concrete material to be screened is placed on the filter paper 9 of the uppermost screening cylinder 4. The vibrating base 1 operates, generating vibration, causing the screening cylinder 4 to vibrate. This causes the filter paper 9 to shake continuously, allowing the concrete material to be screened through the filter paper 9. The material is screened step-by-step through multiple layers of filter paper 9 until the final screened material falls into the collection box 3. The material isolated on the filter paper 9 causes the middle part of the filter paper 9 to fall. This fall of the middle part of the filter paper 9 pulls the connecting rod 15 downwards through the fixing ring 18 and the mounting base 16. The connecting rod 15 transmits gravity to the gravity sensor 13 through the connecting rope 14. The gravity sensor 13 weighs the material on the filter paper 9. When the filter paper 9 needs to be replaced, the screening cylinder 4 is lifted and inverted. The fixing nut 8 is rotated to remove the fixing nut 8 from the first positioning pin 6. Remove the second mounting ring 7 from the first positioning pin 6, rotate the threaded sleeve 19 to remove it from the second positioning pin 17, release the retaining ring 18 from clamping the filter paper 9, remove the filter paper 9 from the first positioning pin 6 and the second positioning pin 17, take out a new filter paper 9, fit the inner wall of the middle of the filter paper 9 onto the second positioning pin 17, fit the positioning holes around the filter paper 9 onto the first positioning pin 6, fit the second mounting ring 7 onto the first positioning pin 6, press the filter paper 9 around its perimeter, screw the retaining nut 8 onto the first positioning pin 6 to fix the position of the second mounting ring 7, so that the second mounting ring 7 and the second anti-slip pad 11 cooperate with the first mounting ring 5 and the first anti-slip pad 10 to clamp and fix the filter paper 9 around its perimeter, screw the threaded sleeve 19 onto the second positioning pin 17, so that the retaining ring 18 cooperates with the mounting base 16 to clamp and fix the middle of the filter paper 9.
