Technical Field
[0001] This utility model belongs to the field of powder storage and transportation technology, specifically relating to a quantitative feeder and the silo made therefrom. Background Technology
[0002] There are already integrated silos that do not require cement bags, which have advantages in storage and transportation and are welcomed in the construction industry.
[0003] However, the quantity of material discharged depends on electronic metering equipment (such as weight sensors). Electronic metering has certain limitations and its manufacturing cost is too high. This problem affects the overall users of the silo and needs to be solved. Utility Model Content
[0004] The technical problem to be solved by this utility model is: how to design a quantitative feeder and the hopper made therefrom, so as to facilitate the control of the feed rate.
[0005] The specific technical solution of this utility model is as follows:
[0006] A quantitative feeder includes a barrel-shaped body that is open at both ends. The hollow part of the barrel-shaped body is a storage space. Each end of the storage space is provided with an opening and closing component. The "opening" and "closing" of the opening and closing component determines the "opening and closing" of the inlet or opening of the storage space.
[0007] The two opening and closing components are two partitions: an upper partition and a lower partition. The "opening" and "closing" of the partitions determine the "opening" and "closing" of the storage space.
[0008] The partition is rotatably connected to the barrel-shaped body, and the partition can be one of the following types:
[0009] The first type: the edge of the partition is hinged to the barrel-shaped body, and the side wall of the barrel-shaped body is provided with a gap for the upper partition to move through;
[0010] The second type: The edge of the lower partition is hinged to the barrel-shaped body. When opening and closing, the movement trajectory of the lower partition is in the vertical plane, and the lower partition passes through the outlet at the lower end of the barrel-shaped body.
[0011] The third type: The middle part of the partition is fixed to the pin, and both ends of the pin are hinged to the barrel-shaped body.
[0012] The partition secures the handle.
[0013] A sealing ring is provided on the top or bottom of the partition. The sealing ring cooperates with the partition to prevent materials from passing through the partition.
[0014] Two pairs of annular clamps are fixed on the inner wall of the barrel-shaped body. Between each pair of annular clamps is a sealing ring installation chamber, and the sealing ring is fixed in the sealing ring installation chamber.
[0015] The side wall of the barrel-shaped body is provided with a breathing slit, and a breathing mask is fixed outside the breathing slit. The space between the breathing mask and the outer wall of the barrel-shaped body is a breathing channel. The breathing slit is connected to the breathing channel. A sealing device is provided at the bottom of the breathing channel. A breathing port is provided on the breathing channel and the breathing port is connected to the outside.
[0016] The top of the breathing channel is the breathing port; the sealing component is a sealing plate, which is fixed to the outer wall of the breathing mask and the barrel-shaped body; in the vertical direction, the breathing seam is located within the corresponding section of the breathing channel; the breathing seam extends in the vertical direction; the cross-sectional shape of the breathing mask is arc-shaped or triangular; the breathing mask is an angle iron, which is welded to the barrel-shaped body; the mask body is fixed above the breathing port.
[0017] A silo, wherein the aforementioned quantitative discharge device is fixed to the bottom surface of the silo body, and the discharge port of the silo body is connected to the inlet of a barrel-shaped body.
[0018] The upper part of the barrel-shaped body of the aforementioned quantitative feeder is welded to the bottom surface of the bin.
[0019] Compared with the prior art, the technical effect of this utility model is that the quantitative feeder of this utility model controls the output amount, which is convenient for metering and does not require electronic metering equipment, thus facilitating the use and promotion of the overall silo.

[0028] Figure 9 A schematic diagram of a quantitative feeder (6). Detailed Implementation
[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0030] like Figure 1-3 A quantitative feeder includes a barrel-shaped body 10 that is open at both ends. The hollow part of the barrel-shaped body 10 is a storage space. Each end of the storage space is movably provided with an opening and closing component. The "opening and closing" of the opening and closing component determines the "opening and closing" of the inlet or opening of the storage space.
[0031] The opening and closing component is similar to a general "valve" that can control the flow path to open or close. It can be a regular valve or a baffle.
[0032] like Figure 3 The two opening and closing parts are two partitions: upper partition 20 and lower partition 21. The opening and closing of the partitions determine the "opening and closing" of the storage space.
[0033] When designed as a partition, the mounting position can be the same thickness as the normal position, which facilitates manufacturing and material cutting. The partition is rotatably connected to the barrel-shaped body 10. The partition can be implemented in the following specific ways:
[0034] The first type: such as Figure 1-3 The edge of the partition is hinged to the barrel 10, and the side wall of the barrel 10 is provided with a gap 11 for the upper partition 20 to move through.
[0035] The second type: such as Figure 8 The edge of the lower partition 21 is hinged to the barrel 10. When it is opened and closed, the movement trajectory of the lower partition 21 is in the vertical plane, and the lower partition 21 passes through the outlet at the lower end of the barrel 10.
[0036] The third type: such as Figure 9 The middle part of the partition is fixed to the pin 201, and both ends of the pin 201 are hinged to the barrel 10.
[0037] In the above three cases, the upper partition 20 and the lower partition 21 are set independently and are not affected by the other. The above three can be combined arbitrarily as long as the requirements are met.
[0038] For example: the upper partition 20 uses the first type, and the lower partition 21 uses the second type; for another example: the upper partition 20 uses the first type, and the lower partition 21 uses the third type; for yet another example: the upper partition 20 uses the third type, and the lower partition 21 uses the second type.
[0039] like Figure 1 To save effort, the partition is used to fix the handle 22.
[0040] like Figure 3 To facilitate sealing, a sealing ring is provided on the top or bottom of the partition, such as the upper sealing ring 14 and the lower sealing ring 13. The sealing ring and the partition cooperate to prevent materials from passing through the partition.
[0041] like Figure 3 Two pairs of annular clamps 15 are fixed on the inner wall of the barrel-shaped body 10. Between each pair of annular clamps 15 is a sealing ring installation chamber 17, and the sealing ring is fixed in the sealing ring installation chamber 17.
[0042] The sealing ring is made of materials such as wool felt or rubber gasket.
[0043] When the dusty material (cement) falls into the sealed barrel 10, the air inside the barrel 10 is not easily expelled, which affects the falling speed of the dusty material. Therefore, further improvements are needed.
[0044] like Figure 3-5 The side wall of the barrel-shaped body 10 is provided with a breathing slit 12, and a breathing mask 30 is fixed outside the breathing slit 12. The space between the breathing mask 30 and the outer wall of the barrel-shaped body 10 is a breathing channel. The breathing slit 12 is connected to the breathing channel. A sealing member 31 is provided at the bottom of the breathing channel, which isolates the breathing channel from the outside world. A breathing port 32 is provided on the breathing channel, which is connected to the outside world.
[0045] The top of the breathing passage is the breathing port 32.
[0046] like Figure 3-5 For secure installation, the sealing component 31 is a sealing plate, which is fixed to the outer wall of the breathing mask 30 and the barrel 10.
[0047] like Figure 3-5 To prevent material from flowing out, the breathing seam 12 is located entirely within the area corresponding to the breathing channel in the vertical direction.
[0048] like Figure 3-5 To prevent falling materials from affecting breathing, the breathing slit 12 extends vertically.
[0049] The cross-sectional shape of the breathing mask 30 is arc-shaped or triangular.
[0050] like Figure 1 For ease of manufacturing, the breathing mask 30 is made of angle iron and is welded to the barrel-shaped body 10.
[0051] like Figure 4-5 To prevent rainwater or foreign objects from entering the breathing port 32, a fixed cover 34 is installed above the breathing port 32.
[0052] like Figure 6-7 A hopper, wherein the aforementioned quantitative discharge device is fixed to the bottom surface 81 of the hopper body 80, and the discharge port of the hopper body 80 is connected to the inlet of the barrel-shaped body 10.
[0053] For secure installation, the upper part 16 of the barrel-shaped body 10 of the aforementioned metering device is welded to the bottom surface 81 of the bin.
[0054] Its working principle is as follows:
[0055] S1. Installation: Secure the quantitative feeder to the hopper.
[0056] S2. Preparation: Both partitions are in the "closed" position.
[0057] S3. Loading: Open the upper partition 20, and the material (such as cement) in the silo 80 enters the barrel 10 from its discharge port. Because the lower partition 21 is in the "closed" state, the metering space of the barrel 10 (that is, the storage space between the two partitions) is quickly filled.
[0058] In this step, because a breathing system is provided, the air inside the barrel 10 can be discharged from the vent 32, which can reduce the impact of this part of the air on the material feeding and make the material feeding speed faster.
[0059] S4, Metering: Close the upper partition 20, and the inlet of the barrel 10 is blocked.
[0060] At this time, the space inside the barrel 10 is a sealed space, and the amount of material inside is a fixed value (in order to be consistent with the original cement construction habits, this fixed value can be the regular weight of a bag of cement, such as 50kg).
[0061] S5. Discharge: Open the lower partition 21 and the material (such as cement) in the barrel 10 flows out from its discharge port.
[0062] In this step, because a breathing system is provided, outside air can enter the barrel 10 through the breathing port 32, thereby preventing negative pressure from being generated at the top of the barrel 10, thus preventing negative pressure effect and obstructing material discharge, and making the discharge speed faster.
[0063] S6. Judgment: Determine whether to continue discharging material. If “yes”, repeat steps S2-S6; if “no”, proceed to step S7.
[0064] S7, End.
[0065] Features of this application:
[0066] S1. This application relates to a non-powered silo device, in which cement flows out by its own gravity. In order to effectively control the feeding speed and amount, a sealed feeding device has been added to the bottom. However, since the air in the feeding device cannot be vented, the flowability of the cement is hindered, thereby affecting production efficiency.
[0067] S2. The breathing system facilitates the removal of air from the quantitative discharge device, improving the smoothness of cement feeding, ensuring smooth cement flow, and increasing work efficiency. The structure is simple, efficient, and cost-effective.
[0068] For other details, please refer to the existing technology.
[0069] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
