[0002] Concrete mixing plants are mainly composed of mixing machines, material weighing systems, material conveying systems, material storage systems, control systems and other ancillary facilities. Sand and gravel cannot be stored in the silo in the open air, because rainwater in the open air will affect the moisture content of sand and gravel, thereby affecting the water-cement ratio of concrete and the quality of finished concrete. At present, the silos in most domestic mixing plants are not designed with drainage systems, which leads to the fact that in the actual operation process, when the moisture content of the stored materials in the silo is high, the accumulated water that is not removed in time will seep out along the discharge port, flow to the transfer belt below, and be sent to the mixing machine, affecting the moisture content of the product. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide a silo and a concrete mixing station, which can solve the problem that when the moisture content of the stored material in the silo is high, the accumulated water that is not removed in time will seep out along the discharge port.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] like Figure 1-Figure 4 As shown, an embodiment of the utility model provides a silo.

[0038] First, the silo includes a side plate 11, a bottom plate 12 and a drainage device, wherein the bottom plate 12 is connected to the bottom of the side plate 11; the bottom plate 12 includes a discharge port 121 and a bottom plate body, the discharge port 121 is a through hole for discharge, the connection position of the discharge port 121 and the bottom plate body protrudes from the top surface of the bottom plate body to form a protrusion 122, the protrusion 122, the bottom plate body and the side plate 11 form a water collection area; the drainage device is connected to the water collection area, and is used to discharge the water in the water collection area to the outside of the silo. See details Figure 1 There are four discharge ports 121, which are arranged in two rows, and two are arranged in each row, wherein the cross section of the discharge ports 121 is rectangular; but not limited to this, the number of discharge ports 121 can also be one, two or more, and the cross-sectional shape of the discharge ports 121 can also be circular or square. The specific number, arrangement position and cross-sectional shape of the discharge ports 121 can be specifically designed by those skilled in the art according to actual needs. It should be noted that the protruding height of the protruding portion 122 can be 100 mm or 110 mm, but it is not limited to this, as long as the protruding portion 122, the side plate 11 and the bottom plate body can form a water collection area, the specific height of the protruding portion 122 can be specifically designed by those skilled in the art according to actual needs. Moreover, the cross section of the protrusion 122 along the radial direction of the discharge port 121 and the dimension along the horizontal direction (i.e., the thickness of the protrusion 122) can be 50 mm or 100 mm, but it is not limited thereto, as long as it can ensure that the protrusion 122 is not damaged under the pressure of the material and water, the specific thickness of the protrusion 122 can be specifically designed by those skilled in the art according to actual needs. In addition, the connection position between the inner wall of the protrusion 122 and the inner wall of the discharge port 121 can be continuous or stepped.

[0039] It can be seen that in the silo provided by the embodiment of the utility model, the connection position of the discharge port 121 and the bottom plate body protrudes from the top surface of the bottom plate body to form a protrusion 122, the bottom plate body and the side plate 11 to form a water collection area; at the same time, a drainage device is provided on the bottom plate body to discharge the water in the water collection area out of the silo. When the moisture content of the stored material in the silo is high, the accumulated water that is not discharged in time will be stored in the water collection area and discharged from the silo through the drainage device, which can prevent the water in the silo from seeping out along the discharge port 121, flowing to the transfer belt below, and then being sent to the mixing main unit, which affects the moisture content of the product.

[0040] In specific implementation, the drainage device includes a drainage blind pipe 2; the drainage blind pipe 2 includes a first part 21 arranged on the top surface of the bottom plate body, and a second part 22 connected to the first part 21 and passing through the bottom plate 12; at least the outer side of the first part 21 of the first part 21 and the second part 22 is wrapped with a water-permeable layer 3 (that is, the outer side of the first part 21 is wrapped with a water-permeable layer, and the outer side of the second part 22 is not wrapped with a water-permeable layer; or the outer sides of the first part 21 and the second part 22 are both wrapped with a water-permeable layer), and the water-permeable layer 3 can play a good filtering role and can effectively prevent gravel from clogging the drainage blind pipe 2. Through the capillary phenomenon and siphon principle of the special microporous structure of the drainage blind pipe 2, water absorption, water permeation and drainage are integrated into one, and water accumulated at the bottom of the silo can be absorbed along the pipe body in multiple directions; the effective water collection range is expanded, and the accumulated water in the silo can be quickly and effectively guided to the drainage blind pipe 2. In addition, the drainage blind pipe 2 is easy to install and maintain. See for details. Figure 1 and Figure 2 The first parts 21 of the two drainage blind pipes 2 are arranged along a straight line and share a second part 22; but not limited to this, the specific number and specific position of the drainage blind pipes 2 and whether the second parts 22 of the plurality of drainage blind pipes 2 are shared or not can be specifically designed by those skilled in the art according to actual needs. It should be noted that the drainage blind pipe 2 can be completely protruded from the top surface of the bottom plate body, partially protruded from the top surface of the bottom plate body, or not protruded from the top surface of the bottom plate body (that is, the bottom plate body is provided with a groove for accommodating the drainage blind pipe 2, and the depth of the groove is less than or equal to the diameter of the drainage blind pipe 2).

[0041] In a specific implementation, the water-permeable layer 3 includes non-woven fabric; or, the water-permeable layer 3 includes geotextile, which has good hydrophilic properties, ensuring that the water-permeable blind pipe is not blocked and can guide moisture to the drainage blind pipe 2 more quickly.

[0042] In a specific implementation, the drainage device further includes a drainage pipe 4, which is connected to the outlet end of the second part 22. The water in the drainage blind pipe 2 is orderly discharged to the outside of the silo through the drainage pipe 4. This prevents the drainage blind pipe 2 from directly discharging the silo from the outlet end of the second part 22 due to height difference and other reasons, and avoids the water from being discharged in an unorganized manner, splashing and affecting the surrounding environment or equipment.

[0043] In specific implementation, the drain pipe 4 includes a funnel portion 41 and a tube body 42; the upper end opening of the funnel portion 41 is larger than the lower end opening and is located below the outlet of the second portion 22; the tube body 42 is connected to the lower end opening of the funnel portion 41. Since the opening of the first portion 21 is larger, the funnel portion 41 can accommodate all the water outlet of the second portion 22, and can effectively collect the water from the second portion 22, so that the water flow is more concentrated, which is convenient for rapid introduction into the drain pipe 4, improves the drainage efficiency, reduces the phenomenon of water accumulation, and avoids water leakage at the opening position of the funnel portion 41. The wide mouth design of the funnel can slow down the speed of water flow entering and reduce the splashing phenomenon caused by the water flow directly impacting the drain pipe 4. It should be noted that the tube body 42 can be straight or Z-shaped. However, it is not limited to this. The structural form of the tube body 42 can be specifically designed by those skilled in the art according to actual needs. The Z-shaped tube body 42 is a horizontal section set in the middle part of the tube body 42.

[0044] In specific implementation, the diameter of the drain pipe 4 ranges from 110 mm to 150 mm. Avoid the situation where the diameter of the drain pipe 4 is too small to effectively drain all the water, causing problems such as water accumulation and overflow; at the same time, avoid the situation where the diameter of the drain pipe 4 is too large. When the drainage of the drainage blind pipe 2 suddenly stops, the water in the large-diameter pipe continues to flow due to inertia, which may produce a greater water hammer effect and damage the pipe. The diameter of the drain pipe 4 is preferably 125 mm, but it is not limited to this. The diameter of the drain pipe 4 can be specifically designed by technicians in this field according to actual needs.

[0045] In specific implementation, the bottom plate body is provided with a first through hole, and the first through hole is provided with a sleeve 5 for penetrating the second part 22. This facilitates the arrangement of the second part 22, the installation of the drainage blind pipe 2, and the later maintenance and replacement of the drainage blind pipe 2. It should be noted that the sleeve 5 is a waterproof sleeve, which prevents water in the second part 22 from penetrating through the sleeve 5 to the hole wall of the first through hole, and at the same time, prevents the sleeve 5 from being damaged by water erosion.

[0046] In specific implementation, the diameter of the drainage blind pipe 2 ranges from 50 mm to 110 mm. Avoid the drainage capacity of the drainage blind pipe 2 being too small, and avoid the difficulty and risk of on-site installation due to the increase in weight and size during transportation, hoisting and installation caused by a too large diameter. The diameter of the drainage blind pipe 2 is preferably 75 mm, but is not limited to this. The diameter of the drainage blind pipe 2 can be specifically designed by those skilled in the art according to actual needs.

[0047] In specific implementation, in the direction perpendicular to the horizontal plane, the height of the position where the free end of the first part 21 is located is higher than that of the other end, so that the water in the drainage blind pipe 2 can be discharged in time, and the water can be prevented from being stored in the drainage pipe 4, thereby failing to achieve the purpose of drainage; the ratio of the height difference between the two ends of the first part 21 to the length of the first part 21 is in the range of 0.5% to 1%, that is, the slope is 0.5% to 1%, but it is not limited thereto. The slope of the drainage blind pipe 2 can be specifically designed by those skilled in the art according to actual needs. It should be noted that the slope of the drainage blind pipe 2 is achieved by finding the slope on the contact surface between the bottom plate 12 of the bottom plate body and the drainage blind pipe 2.

[0048] In specific implementation, the height of the protrusion 122 ranges from 50 mm to 150 mm. Avoid the protrusion 122 being too small, which results in insufficient water collection capacity in the water collection area, and avoid the protrusion 122 being too large, which results in too much material being contained in the water collection area. Due to the stopping effect of the protrusion 122, the material in the water collection area is not easy to be discharged from the silo through the discharge port 121. The height of the protrusion 122 is preferably 100 mm, but is not limited thereto. The height of the protrusion 122 can be specifically designed by those skilled in the art according to actual needs.

[0049] In specific implementation, the drainage device includes a drainage ditch 6 located below the bottom plate 12. It is convenient for the water in the water collection area to be drained away in an organized manner, avoiding the water from being directly discharged to the ground of the transfer belt layer, affecting the ground environment, and avoiding the accumulation of drainage on the ground of the transfer belt layer, and the high humidity affecting the equipment.

[0050] An embodiment of the utility model provides a concrete mixing station, comprising the above-mentioned silo.

[0051] It can be seen that the embodiment of the utility model provides a concrete mixing station, in which the connection position between the discharge port 121 of the silo and the bottom plate body protrudes from the top surface of the bottom plate body to form a protrusion 122, the bottom plate body and the side plate 11 to form a water collection area; at the same time, a drainage device is provided on the bottom plate body to discharge the water in the water collection area out of the silo. When the moisture content of the stored material in the silo is high, the accumulated water that is not discharged in time will be stored in the water collection area and discharged from the silo through the drainage device, which can prevent the water in the silo from seeping out along the discharge port 121, flowing to the transfer belt below, and then being sent to the mixing main unit, which affects the moisture content of the product.
