Description

Technical Field

[0001] This utility model belongs to the field of calcium-zinc stabilizer preparation technology, and specifically relates to a feeding device for preparing calcium-zinc stabilizers. Background Technology

[0002] In the preparation of calcium-zinc stabilizers, the feeding device is a critical piece of equipment, and its accuracy plays a decisive role in product quality. Traditional feeding pipes often use a relatively simple gravity-flow conveying method. However, in actual production, because the feeding pipe cannot quantitatively discharge the material, it is difficult to accurately control the proportions of the various components of the calcium-zinc stabilizer. This not only causes fluctuations in product quality and reduces the product qualification rate, but may also lead to frequent adjustments and rework during the production process, increasing production costs and seriously affecting production efficiency and corporate economic benefits. Utility Model Content

[0003] This utility model addresses the problems of existing technologies by providing a feeding device for preparing calcium-zinc stabilizers. The specific technical solution is as follows:

[0004] A feeding device for preparing a calcium-zinc stabilizer includes a storage silo, a feeding port located at the top of the storage silo, and a feeding pipe located at the bottom of the storage silo. The feeding pipe contains a metering mechanism, which includes:

[0005] An upper baffle and a lower baffle are arranged at intervals along the axial direction of the feeding pipe, forming a temporary feeding space between the upper baffle and the lower baffle. The upper baffle has an inlet that connects to the storage bin, and the lower baffle has an outlet.

[0006] A baffle plate 1 rotatably connected to the upper baffle plate, a baffle plate 2 rotatably connected to the lower baffle plate, and a synchronizing link connecting baffle plate 1 and baffle plate 2;

[0007] The synchronous linkage drives baffle one and baffle two to rotate synchronously, so that the metering mechanism has:

[0008] In the first state, baffle one closes the inlet and baffle two opens the outlet;

[0009] In the second state, baffle one and baffle two respectively close the inlet and outlet;

[0010] In the third state, the first baffle opens the inlet, and the second baffle closes the outlet.

[0011] As a further technical solution of this utility model, the rotation path of the synchronous connecting rod is configured as follows:

[0012] During the quantitative feeding process, the process cycles through the third state, the second state, the first state, and the second state in sequence.

[0013] As a further technical solution of this utility model, a throttling mechanism is provided at the bottom of the feeding pipe, the throttling mechanism comprising:

[0014] A fixed ring that fits around the feed tube, a conical head that is coaxially inserted into the bottom of the feed tube, and a telescopic rod that connects the fixed ring and the conical head;

[0015] An annular throttling channel is formed between the conical head and the bottom of the feeding pipe, and the telescopic rod adjusts the area of ​​the throttling channel by axial displacement.

[0016] As a further technical solution of this utility model, the bottom of the conical head is connected to an output motor, the output end of the output motor is connected to a sleeve, and the sleeve is fitted onto the bottom of the synchronous connecting rod through a toothed key to form a telescopic structure.

[0017] The beneficial effects of this utility model are as follows:

[0018] In this application, by setting up a quantitative mechanism and using a closed feeding and discharging alternation mechanism in the temporary feeding space, the amount of material fed each time is kept constant. During the quantitative process, the feeding and discharging channels are strictly isolated to avoid cross-interference between feeding and discharging.

[0019] This application also includes a throttling mechanism, the area of ​​which can be dynamically adjusted according to the material flow rate to maintain a stable output per unit time and reduce manual intervention. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] Figure 1 A schematic diagram of the overall structure of a feeding device for preparing calcium-zinc stabilizers is shown. Figure 2 A schematic diagram of the internal structure of a feeding device for preparing calcium-zinc stabilizers is shown. Figure 1 and Figure 2 The feeding device for preparing calcium-zinc stabilizer includes a storage silo 110, a feeding port 120, and a feeding pipe 130. The feeding port 120 is located at the top of the storage silo 110 and is used to feed material into the storage silo 110. The feeding pipe 130 is located at the bottom of the storage silo 110 and is used to discharge the material in the storage silo 110 to realize feeding.

[0031] Figure 3 A schematic diagram of the structure at feed pipe 130 is shown; Figure 3 In the feed pipe 130, a metering mechanism 200 and a throttling mechanism 300 are installed. The metering mechanism 200 is located inside the feed pipe 130 and is used to pre-meter the material to form a precise temporary feeding area to ensure the discharge ratio. The throttling mechanism 300 is located at the bottom outlet of the feed pipe 130 and is used to control the outflow speed of the material. When the material has good flowability, the throttling area is reduced to decrease the discharge speed and avoid excessive discharge. If the material has poor flowability, the throttling area is appropriately increased to accelerate the discharge and ensure a relatively stable discharge volume per unit time.

[0032] Figure 4 A schematic diagram of the metering mechanism 200 in its first state is shown; Figure 5 A schematic diagram of the metering mechanism 200 in the second state is shown; Figure 6 A schematic diagram of the metering mechanism 200 in the third state is shown; Figures 4-6In the feeding mechanism 200, an upper baffle 210, a lower baffle 220, and a synchronous connecting rod 230 are provided. The upper baffle 210 and the lower baffle 220 are arranged axially along the feeding pipe 130 to form a temporary feeding space. The upper baffle 210 has an inlet 211 to connect the temporary feeding space to the storage bin 110, and the lower baffle 220 has an outlet 221 to connect the temporary feeding space to the outside. A first baffle 212 is rotatably connected to the upper baffle 210, and a second baffle 222 is rotatably connected to the lower baffle 220. The synchronous connecting rod 230 is also provided. A connecting rod 230 is used between baffle 1 212 and baffle 222 to enable them to rotate synchronously. When the synchronous connecting rod 230 rotates, the metering mechanism 200 has at least a first state, a second state, and a third state. In the first state, baffle 1 212 blocks the inlet 211, and the outlet 221 is open to allow the material in the temporary feeding space to flow out. In the second state, baffle 1 212 blocks the inlet 211, and baffle 222 blocks the outlet 221. In the third state, baffle 222 blocks the outlet 221, and the inlet 211 is open to replenish the material in the temporary feeding space.

[0033] In actual use, the synchronous linkage 230 is driven to rotate. At this time, the first baffle 212 and the second baffle 222 rotate synchronously. The inlet 211 opens first, while the outlet 221 closes. Figure 6 As shown, the metering mechanism 200 is in the third state. Material in the storage bin 110 flows into the temporary discharge space through the inlet 211, while the outlet 221 is closed to prevent simultaneous inflow and outflow, ensuring accurate metering. When the temporary discharge space is full, the driving synchronous linkage 230 rotates again, closing both the inlet 211 and outlet 221. Figure 5 As shown, the metering mechanism 200 is in the second state, where the material quantity is fixed and the storage bin 110 will not continue to replenish the temporary feeding space. The driving synchronous linkage 230 continues to rotate, at which point the inlet 211 remains closed while the outlet 221 opens. The material in the temporary space can then flow to the outside through the outlet 221 to form feeding, until the material in the temporary feeding space is exhausted. The driving synchronous linkage 230 continues to rotate, at which point both the inlet 211 and the outlet 221 are closed, and the metering mechanism 200 is back in the second state, preparing for subsequent replenishment. Thus, it can be seen that when the temporary feeding space continuously discharges metered material, the metering mechanism 200 alternates between the third state, the second state, the first state, and the second state. The transition is achieved by closing both the inlet 211 and the outlet 221 in the second state, avoiding the simultaneous opening of the inlet 211 and the outlet 221.

[0034] It should be noted that the rotation of the synchronous link 230 can be intermittent or continuous, neither of which affects the change of the working state of the metering mechanism 200.

[0035] Figure 7 A schematic diagram of the throttling mechanism 300 is shown; Figure 7 In the process, the throttling mechanism 300 includes a fixed ring 310, a telescopic rod 320, and a conical head 330. The fixed ring 310 is sleeved around the feed pipe 130. The pointed end of the conical head 330 is coaxially inserted into the bottom of the feed pipe 130. There is an annular gap between the conical head 330 and the bottom of the feed pipe 130 to form a throttling channel. The telescopic rod 320 is connected between the fixed ring 310 and the conical head 330 to adjust the area of ​​the throttling channel.

[0036] The fixed end of the telescopic rod 320 is installed on the fixed ring 310, and the free end of the telescopic rod 320 is connected to the conical head 330. When the telescopic rod 320 extends or retracts, it can drive the conical head 330 to move along the axial direction of the feeding pipe 130, thereby adjusting the throttling area between the conical head 330 and the feeding pipe 130. This allows for flexible control of the material outflow rate, and the conical head 330 can fit against the outlet of the feeding pipe 130 to form a ring seal, thus closing the feeding pipe 130.

[0037] See also Figure 7 The bottom of the conical head 330 is connected to an output motor 240, and the output end of the output motor 240 is connected to a sleeve 250. The sleeve 250 is fitted onto the bottom of the synchronous connecting rod 230 through a toothed key to form a telescopic structure. By placing the output motor 240 at the bottom of the conical head 330, material contact with it is avoided, which can protect the output motor 240. At the same time, the toothed key forms a connection between the sleeve 250 and the synchronous connecting rod 230, which can ensure that the two rotate synchronously and can extend axially to accommodate the displacement of the conical head 330.

[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
