However, after the material distribution device works for a period of time, the gate valve will be affected by abrasion, which affects the adjustment accuracy of the gate valve. Therefore, the gate valve needs to be adjusted or replaced, and thus the scheme of using the gate valve has the problems of difficult maintenance and high use cost. SUMMARY

[0037] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] The following is based on the appendix Figure 1 The material dispensing device according to an embodiment of the present invention is described.

[0039] The material distribution device of this invention includes a cylinder 1, a pressure stabilizing pipe group 2, a feeding pipe 3, and a discharging pipe 4.

[0040] like Figure 1 As shown, the upper end of the cylinder 1 is provided with an opening, and the lower end of the cylinder 1 is provided with a bottom plate 5; the pressure stabilizing pipe group 2 is spaced apart from the bottom plate 5 in the vertical direction, and part of the feeding pipe 3 extends into the pressure stabilizing pipe group 2 to convey materials into the pressure stabilizing pipe group 2; the discharge pipe 4 is located on the outside of the cylinder 1 and is connected to the discharge port 101 located on the cylinder 1.

[0041] like Figure 1As shown, the material distribution device of this embodiment of the invention is equipped with a pressure stabilizing pipe group 2. The material is fed in by the feeding pipe 3. The liquid level in the cylinder 1 first reaches the liquid level of the discharge port 101 so that the material can be output from the discharge pipe 4. As the material is fed in, the liquid levels in the pressure stabilizing pipe group 2 and the feeding pipe 3 rise, and finally stabilize at a state where the liquid level in the feeding pipe 3 is higher than the liquid level in the pressure stabilizing pipe group and the liquid level in the pressure stabilizing pipe group is higher than the liquid level at the discharge port. In this state, a stable pressure difference is formed between the liquid level in the feeding pipe 3, the liquid level in the pressure stabilizing pipe group 2 and the liquid level at the discharge port 101, thereby enabling the material to be discharged evenly from the discharge port 101.

[0042] The material distribution device of this embodiment of the invention, by setting up a pressure stabilizing pipe group 2, creates a stable pressure difference within the material distribution device, thereby achieving the effect that the material can be evenly discharged from the discharge port 101.

[0043] Therefore, the material dispensing device of this invention has the characteristics of low cost and easy maintenance.

[0044] The following is based on the appendix Figures 1-2 The material dispensing device of the present invention will be further described in an embodiment.

[0045] The material distribution device of this invention includes a cylinder 1, a pressure stabilizing pipe group 2, a feeding pipe 3, and a discharging pipe 4.

[0046] like Figure 1 As shown, the upper end of the cylinder 1 is provided with an opening, and the lower end of the cylinder 1 is provided with a bottom plate 5. In other words, the cylinder 1 is a cylindrical structure with a closed lower end and an open upper end.

[0047] The voltage regulator assembly 2 is spaced apart from the base plate 5 in the vertical direction, meaning that the lower end face of the voltage regulator assembly 2 does not contact the base plate 5.

[0048] Part of the feed pipe 3 extends into the pressure stabilizing pipe assembly 2 to convey material into the pressure stabilizing pipe assembly 2;

[0049] The discharge pipe 4 is located on the outside of the cylinder 1 and is connected to the discharge port 101 located on the cylinder 1. It is understood that the discharge port 101 is located on the side wall of the cylinder 1.

[0050] The material distribution device of this embodiment of the invention features a pressure stabilizing pipe assembly 2. Material is fed in through the feed pipe 3, and the liquid level inside the cylinder 1 initially reaches the liquid level at the discharge port 101, allowing the material to be output through the discharge pipe 4. As material is fed in, the liquid levels in the pressure stabilizing pipe assembly 2 and the feed pipe 3 rise, eventually stabilizing at a state where the liquid level in the feed pipe 3 is higher than that in the pressure stabilizing pipe assembly, and the liquid level in the pressure stabilizing pipe assembly is higher than that at the discharge port. In this state, a stable pressure difference is formed between the liquid levels in the feed pipe 3, the pressure stabilizing pipe assembly 2, and the discharge port 101, thereby enabling the material to be uniformly discharged from the discharge port 101. Compared to related technologies that use gate valves for regulation, the material distribution device of this embodiment of the invention does not require gate valves and requires no maintenance, offering advantages such as low cost and ease of maintenance.

[0051] In some embodiments, there are multiple discharge pipes 4, which are spaced apart on the outer side of the cylinder 1 in the circumferential direction and are connected to multiple discharge ports 101 provided on the side wall of the cylinder 1.

[0052] The material distribution device of this embodiment of the invention, by setting multiple discharge pipes 4, can further enable the material distribution device to discharge the material evenly.

[0053] In some embodiments, the minimum projected distance between the outlet 101 and the base plate 5 in the vertical direction is greater than the minimum projected distance between the lower end face of the voltage regulator assembly 2 and the base plate 5 in the vertical direction. In other words, as shown in the figure, in the vertical direction, the lower end face of the voltage regulator assembly 2 is located below the outlet 101.

[0054] Optionally, the projection distance between the lower end face of the pressure stabilizing tube assembly 2 and the discharge port 101 in the vertical direction is 50mm-150mm.

[0055] In some embodiments, such as Figure 1 As shown, the pressure stabilizing pipe assembly 2 includes a main pressure stabilizing pipe assembly 201 and a secondary pressure stabilizing pipe assembly 202. The secondary pressure stabilizing pipe assembly is sleeved on the outside of the main pressure stabilizing pipe assembly 201, and part of the feed pipe 3 is located in the main pressure stabilizing pipe assembly 201 to convey materials into the main pressure stabilizing pipe assembly 201.

[0056] like Figure 1 As shown, the upper surfaces of the main voltage regulator 201 and the secondary voltage regulator 202 are flush.

[0057] Furthermore, there are multiple secondary voltage regulator fittings 202, which are arranged radially at intervals on the outside of the main voltage regulator fitting 201.

[0058] Optionally, the number of secondary pressure stabilizing fittings 202 is 1-4.

[0059] Furthermore, the projection distance between the lower end face of the main voltage regulator 201 and the base plate 5 in the vertical direction is greater than the projection distance between the lower end face of the multiple secondary voltage regulators 202 and the base plate 5 in the vertical direction; in other words, in the vertical direction, the lower end face of the main voltage regulator 201 is located above the lower end face of the multiple secondary voltage regulators 202.

[0060] The projection distance between the lower end face of the multiple secondary voltage stabilizing pipes 202 and the base plate 5 in the vertical direction decreases from the inside to the outside in the radial direction. In other words, in the vertical direction, the lower end face of the multiple secondary voltage stabilizing pipes 202 decreases from the inside to the outside in the radial direction.

[0061] It is understandable that the main pressure stabilizing pipe 201 is located at the center of the pressure stabilizing pipe group 2, and part of the feed pipe 3 extends into the main pressure stabilizing pipe 201 to convey materials into the main pressure stabilizing pipe 201.

[0062] The material distribution device of this embodiment of the invention is configured with a pressure-stabilizing pipe group 2, including a main pressure-stabilizing pipe 201 and multiple secondary pressure-stabilizing pipes 202. Material is fed in through a feed pipe 3, and the liquid level inside the cylinder 1 first reaches the liquid level at the discharge port 101, allowing the material to be output through the discharge pipe 4. As material is fed in, the liquid levels in the pressure-stabilizing pipe group 2 and the feed pipe 3 rise, eventually stabilizing at a state where the liquid level in the feed pipe 3 is higher than the liquid level of the main pressure-stabilizing pipe 201, the liquid level in the main pressure-stabilizing pipe group 2 is higher than the liquid level of the secondary pressure-stabilizing pipes 202, and the liquid level in this pressure-stabilizing pipe group 2 is higher than the liquid level of the discharge pipe 4. It can be understood that the liquid levels of the multiple secondary pressure-stabilizing pipes 202 decrease sequentially from the inside out, and the lowest liquid level of the secondary pressure-stabilizing pipe 202 is higher than the liquid level at the discharge port 101.

[0063] Therefore, under the above conditions, a stable pressure difference is formed between the liquid level in the feed pipe 3, the liquid level in the main pressure stabilizing pipe 201, the liquid levels in the multiple secondary pressure stabilizing pipes 202, and the liquid level in the discharge port 101, thereby enabling the material to be discharged uniformly from the discharge port 101. Compared with the related technology that uses gate valves for regulation, the material distribution device of this embodiment does not require gate valves and requires no maintenance, thus having the characteristics of low cost and easy maintenance.

[0064] In another embodiment, such as Figure 2 As shown, the material distribution device of this embodiment of the invention also includes a material distribution cylinder 6, which is arranged radially between the cylinder body 1 and the pressure stabilizing pipe group 2; the lower end of the material distribution cylinder 6 is connected to the bottom plate 5, and a material distribution port 601 is provided on the material distribution cylinder 6 corresponding to the discharge port 101.

[0065] In some embodiments, an annular support plate 7 is provided at the lower end of the dispensing cylinder 6, the outer edge of the annular support plate 7 is connected to the inner sidewall of the dispensing cylinder 6, and the annular support plate 7 is provided on the bottom plate 5.

[0066] Optionally, the annular support plate 7 and the base plate 5 are sealed together.

[0067] The material distribution device of this invention provides an annular support plate 7 at the lower end of the material distribution cylinder 6, which can better fix the material distribution cylinder 6 to the base plate 5. At the same time, the annular support plate 7 and the base plate 5 are sealed together, which can prevent material from seeping into the outside of the material distribution cylinder 6 from the connection between the annular support plate 7 and the base plate 5.

[0068] In some embodiments, such as Figure 2 As shown, the material distribution device of this embodiment of the invention also includes an annular partition screen 8, which is detachably disposed on the side wall of the material distribution cylinder 6.

[0069] Optionally, the annular screen 8 can be provided on the inner wall surface of the distribution cylinder 6 and the outer or inner wall surface of the distribution cylinder 6. The specific arrangement can be determined according to the actual situation.

[0070] In some embodiments, an annular cavity 9 is defined between the side wall of the dispensing cylinder 6 and the side wall of the cylinder 1. A plurality of partitions are provided in the annular cavity 9, and the plurality of partitions are respectively disposed between adjacent discharge ports 101 to divide the annular cavity 9 into a plurality of arc-shaped cavities 901.

[0071] The material distribution device of this invention, by setting multiple baffles, can ensure uniform material output from each material distribution pipe.

[0072] In some embodiments, such as Figure 3 As shown, the axes of the multiple discharge pipes 4 are parallel.

[0073] The material distribution device of this invention sets the axes of multiple discharge pipes 4 to be parallel to each other, which facilitates the arrangement of subsequent pipelines of multiple discharge pipes 4.
