Description
Technical Field
[0001] The present invention relates to the technical field of ash volume monitoring of ash storage tanks, and particularly relates to a simple device for monitoring the ash volume of ash storage tanks. Background Art
[0002] A cement ash tank, also known as a bulk material tank, is used to receive, store, and transport materials such as cement. Its form is vertical; with an elliptical head; and a cylindrical barrel. The lower part of the tank is conical, with an elliptical bottom. The cement tank is a device used on construction sites to store materials such as cement, and it mainly has the following functions: (1) Storing cement: Construction sites often need to use a large amount of cement for construction. The cement tank can store a large amount of cement to ensure the continuity and smoothness of construction; (2) Ensuring the quality of materials: The cement stored in the cement tank can avoid the influence of natural factors such as sun exposure and rain on the materials, and at the same time, it can also avoid the mixing of sundries such as soil with the cement, which affects the quality of the materials; (3) Ensuring the safety of construction: There are special mechanical devices inside the cement tank that can transport the cement to the required places, avoiding workers from transporting and handling cement at high altitudes, and improving the safety of construction.
[0003] Generally, for grouting projects, 2 - 3 cement ash tanks are erected beside the well site grouting station. The cement truck transports the cement from the cement factory to the well site and pumps it into the ash tank for use during grouting. The ash tank body is made of an iron wall, and the partition on the tank body is painted with blue and white paint. Since the tank body is opaque, it is impossible to observe the remaining amount of cement when using the cement in the tank. Generally, a rope is installed on the tank body, and an iron block is tied to the rope. The rope is pulled to strike the tank body with the iron block, and the position of the cement surface is judged according to the different sounds emitted by the empty tank and the full tank, so as to calculate the remaining amount of cement. Although this method is simple, it requires manual knocking and cannot automatically monitor the change of the cement amount in the tank. Summary of the Invention

[0035] In the embodiment of the present invention, rubber stoppers 7 are installed on the outer sides of the two parts of the fixed cylinder body 1 to fix the fixed cylinder body 1 and seal the drilled holes to prevent cement ash from leaking out through the drilled holes during the ash filling process.
[0036] The seesaw rod movable seam 9 is located at the connection of the two parts of the fixed cylinder body 1. A dust-proof foam 10 is provided in the gap outside the seesaw rod movable seam 9 at the connection.

[0043] In the embodiment of the present invention, the simple device 100 is installed at a position on the tank wall 200 near the upper and lower ash tank ladders and couplings.
[0044] In the embodiment of the present invention, the simple device 100 is installed at a position on the ash tank wall 200 near the upper and lower ash tank ladders and couplings.
[0045] Combined Figures 1 - 3 , the simple device 100 of the present invention is mainly composed of a fixed cylinder 1 and a seesaw rod 2.
[0046] 1. Fixed cylinder
[0047] Its function is to connect each component. First, drill holes in the ash tank wall 200, install and fix the cylinder 1 on the ash tank wall 200 and then seal it tightly. Part of the cylinder 1 is inside the ash tank and part is outside the ash tank. For the convenience of installation, it can be made into two sections and connected by screw threads in the middle. At the one-third position outside the cylinder, drill holes to string cross bars for installing the seesaw rod 3.
[0048] The cylinder 1 can be circular or elliptical. Generally, a thick-walled steel pipe is cut in the middle, iron sheets are welded on the cut surface, a seesaw rod moving gap 9 is left in the middle, and then the two halves are welded together again. The gaps outside the moving gap 9 are filled with dust-proof foam 10 to prevent ash.
[0049] Rubber plugs 7 are installed at both ends of the cylinder 1, and their sizes are slightly larger than the cylinder 1 so that they can be inserted into the ash tank through the drilled holes. Their function is to fix the cylinder 1 and seal the drilled hole gaps to prevent cement ash from leaking out through the gaps during the ash filling process.
[0050] A telescopic dust-proof cloth 8 is installed at the inner top of the cylinder 1. One end of the cloth is fixed on the cylinder 1 and the other end is fixed on the seesaw rod 2. Its function is that when the ash surface exceeds the pressing plate 4, the seesaw rod 2 sinks and pulls the telescopic dust-proof cloth 8 to close the seesaw rod moving gap 9 and prevent ash from leaking out through the seesaw rod moving gap 9.
[0051] A rain shield 6 is installed outside the cylinder 1, and its length is preferably the longest without affecting the up and down movement of the seesaw rod 2. Its function is to prevent rainwater from entering the ash tank through the seesaw rod moving gap 9.
[0052] 2. Seesaw rod
[0053] The seesaw rod 2 is made of a steel bar as thick as a finger. Drill holes in the middle position and fix it on the fixed point 3 of the cylinder. Its principle is similar to that of a seesaw. The seesaw rod is required to be heavier outside than inside. In the natural ash-free state, the head of the seesaw rod (colored flag 5) sinks.
[0054] A pressing plate 4 is installed at the tail of the seesaw rod 2 inside the tank. The pressing plate should not be too large, and its size should not exceed the size of the drilled hole in the tank wall. Its function is that when the cement covers the pressing plate 4, it sinks. A colored flag 5 is installed at the head of the seesaw rod 2 outside the tank to facilitate observing the rising and falling changes of the seesaw rod 2.
[0055] The cement storage tank for general grouting consists of 5 - 7 sections. There is a base 400 at the bottom of the cement storage tank. This device can be installed near the climbing ladder and coupling of the upper and lower ash tanks. For improving the accuracy of ash quantity calculation, it can be installed with increased density.
[0056] As Figure 3 shown, the process of monitoring and calculating the ash quantity in the storage tank using the simple device for monitoring the ash quantity in the storage tank provided by the embodiment of the present invention includes:
[0057] The first step: Drill holes in the ash tank wall 200, install the cylinder body 1 for sealing, and then install the seesaw rod 2, etc. For improving the monitoring accuracy, it can be installed with increased density at the coupling and the middle position of the ash tank.
[0058] The second step: Inject ash into the ash tank. When the cement ash exceeds the pressure plate 4, the tail of the seesaw rod 2 sinks, and the head of the seesaw rod 2 rises. The position of the cement surface 300 can be observed. During the process of using the cement in the tank, after the cement surface 300 drops and exposes the pressure plate 4, the tail of the seesaw rod 2 rises, and the head of the seesaw rod 2 sinks, and the position of the cement surface 300 can also be observed. Based on the position of the cement surface 300 and the diameter of the ash tank, the remaining cement quantity in the tank can be calculated.
[0059] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
