[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0038] A screw feeder is a conveying device for handling bulk solids. The principle of a screw feeder is to use rotating screw blades moving inside a conveying pipe to move powder or granular materials forward along the pipe, thus realizing the conveying process from the feeding device to the discharge port.

[0039] To ensure accurate and quantitative material delivery by the screw feeder, a slide gate valve is usually installed at the discharge port of the screw feeder. The opening and closing action of the slide gate valve enables timely start and stop of the feeder.

[0040] However, during the feeding process of the screw feeder, some material may stick to the slide plate of the slide valve, which can easily cause the slide plate to jam and prevent the slide valve from opening and closing properly.

[0041] Based on this, this application discloses a slide gate valve that can quickly clean up materials adhering to the slide gate, thus solving the problem of the slide gate valve being unable to open and close normally.

[0042] like Figure 1 and Figure 2 As shown, the slide gate valve 100 disclosed in this application includes: a housing 101, a slide gate 102, an actuator 103, a guide rail 104, a clamping plate 105, a base plate 106, an adjusting assembly 107, a connecting rod 108, and a flange 109.

[0043] The housing 101 has a hollow structure, and its sidewalls have a feed inlet and a discharge outlet. The feed inlet of the housing 101 is used to connect with the discharge outlet of the hopper of the screw feeder, and the discharge outlet of the housing 101 is located at the lower end of the housing 101 so that the material falls under the action of gravity. Optionally, the discharge outlet is connected via a flange 109.

[0044] In this paper, the first direction and the third direction are both parallel to the plane where the feed inlet is located, and the first direction and the third direction are perpendicular. The second direction is the axial direction of the feed inlet. The second direction, the third direction, and the first direction are all perpendicular to each other.

[0045] The insert plate 102, driver 103, guide rail 104, clamping plate 105, base plate 106, adjustment assembly 107 and connecting rod 108 are all installed inside the housing 101.

[0046] The insert plate 102 has a flat plate structure, and the first direction of the insert plate 102 is the direction in which the insert plate 102 moves along the guide rail 104. The third direction of the insert plate 102 is perpendicular to the first direction, and the insert plate 102 is slidably installed on both sides of the third direction along the guide rail 104.

[0047] The end of the insert plate 102 away from the discharge port along the first direction is connected to the driver 103. The driver 103 includes, but is not limited to, a cylinder, a linear motor, or a lead screw and nut assembly, which are structures that enable the insert plate 102 to move in a straight line.

[0048] By setting the driver 103, the mechanical drive of the insertion plate 102 during the movement process can be realized, which can replace the operator's manual movement of the insertion plate 102 and help reduce the labor intensity of the operator during the movement of the insertion plate 102.

[0049] The guide rail 104 extends along a first direction and is fixed within the housing 101. The fixing methods between the guide rail 104 and the housing 101 include, but are not limited to, threaded connections, adhesive bonding, or snap-fit ​​connections. The guide rail 104 includes, but is not limited to, a C-shaped guide rail. An insert plate 102 is inserted into the C-shaped guide rail and moves along the C-shaped guide rail under the driving action of the driver 103. Optionally, two guide rails 104 are used in this document and arranged side-by-side along a third direction. The insert plates 102 are connected to the guide rails 104 one-to-one along their respective sides in the third direction.

[0050] In this embodiment, two guide rails 104 are provided, which can improve the stability of the slide plate 102 during movement, prevent the slide plate 102 from tilting, and improve the accuracy of the opening degree of the slide plate valve 100.

[0051] In some embodiments, the thickness of the insert plate 102 on both sides along the third direction is less than the thickness of the insert plate 102 at the middle position along the third direction. This can be understood as the insert plate 102 forming a stepped structure on both sides and at the middle position along the third direction. The thickness of the insert plate 102 is the dimension of the insert plate 102 along the second direction.

[0052] The thickness of the insert plate 102 on both sides along the third direction is small, which makes it easy to insert into the guide rail 104; the stepped structure of the insert plate 102 can limit the insertion plate 102 and the guide rail 104 along the third direction after they are connected, preventing the insert plate 102 from moving relative to the guide rail 104 in the third direction.

[0053] Combination Figure 2 and Figure 3 As shown, the clamping plate 105 and the base plate 106 of the slide valve 100 disclosed in this application embodiment are arranged along the second direction, and the clamping plate 105 and the base plate 106 have a gap along the second direction, which is the insertion space for the slide plate 102 to be inserted.

[0054] Optionally, the distance between the clamping plate 105 and the base plate 106 along the second direction is adjustable to adjust the clamping force of the clamping plate 105 and the base plate 106 on the slide plate 102. Under a larger clamping force, the slide plate 102 can ensure the sealing performance of the slide valve for highly fluid fine powder.

[0055] It should be noted that in the slide gate valve disclosed in this application embodiment, the slide gate 102 can move along the guide rail 104 in a first direction, and during the movement, the slide gate 102 can be inserted between the clamping plate 105 and the base plate 106. If the slide gate 102 gets stuck, the distance between the clamping plate 105 and the base plate 106 in a second direction can be increased, so that the slide gate 102 can be inserted between the clamping plate 105 and the base plate 106. By repeatedly inserting and withdrawing the slide gate 102 between the clamping plate 105 and the base plate 106, the slide gate rubs against the clamping plate and the base plate respectively, thereby achieving rapid cleaning of materials adhering to the slide gate 102 and saving maintenance time of the slide gate valve 100.

[0056] The distance between the clamping plate 105 and the base plate 106 in this embodiment is adjustable, thereby changing the clamping force of the clamping plate 105 and the base plate 106 on the insert plate 102.

[0057] Combination Figures 3 to 5 As shown, this application discloses a connection method between a clamping plate 105 and a base plate 106, which allows for adjustment of the distance between the clamping plate 105 and the base plate 106. This application is not limited to this connection method; other connection methods that allow for adjustable distance between the clamping plate 105 and the base plate 106 are also within the scope of protection.

[0058] The base plate 106 is, but is not limited to, fixedly connected to the guide rail 104. The connection method between the base plate 106 and the guide rail 104 includes, but is not limited to, threaded connection. The clamping plate 105 can move relative to the base plate 106 in a second direction, thereby changing the distance between the clamping plate 105 and the base plate 106.

[0059] One end of the clamping plate 105 along the first direction (near the flange 109) is connected to the base plate 106 via a connecting rod 108; the other end of the clamping plate 105 along the first direction (away from the flange 109) is connected to the housing 101 via an adjusting assembly 107.

[0060] In some embodiments, the insert plate 102 and the base plate 106 are arranged along a first direction, and the insert plate 102 is located at the upper end of the base plate 106 along the first direction, that is, at the first end of the base plate 106 and the clamping plate 105.

[0061] The clamping plate 105 has a first end that is fixedly connected to the base plate 106, including but not limited to a fixed connection. The second end of the clamping plate 105 can be adjusted via the adjusting assembly 107 to change the distance between the clamping plate 105 and the base plate 106. This can be understood as follows: the distance between the first end of the clamping plate 105 and the first end of the base plate 106 along the second direction is not adjustable, while the distance between the second end of the clamping plate 105 and the second end of the base plate 106 along the second direction is adjustable.

[0062] It should be noted that the distance between the second end of the clamping plate 105 and the base plate 106 in this paper is adjustable, which can reduce the difficulty of the clamping plate 105 moving relative to the base plate 106 in the second direction, making it easier for the operator to operate; and can improve the efficiency of adjusting the distance between the clamping plate 105 and the base plate 106.

[0063] like Figure 4 As shown, the adjustment assembly 107 includes: a connecting seat 1071, an adjustment rod 1072, and an adjustment nut 1073.

[0064] The connecting seat 1071 is fixedly connected to the clamping plate 105. The connecting seat 1071 and the clamping plate 105 are connected by means including but not limited to threaded connectors, welding or snap-fit.

[0065] The adjusting rod 1072 is arranged along the second direction, and one end of the adjusting rod 1072 along the second direction is fixedly connected to the connecting seat 1071, while the other end of the adjusting rod 1072 along the second direction extends out of the housing 101. The adjusting rod 1072 and the connecting seat 1071 are connected by, but are not limited to, welding, integral molding, or threaded connection.

[0066] Optionally, the side wall of the housing 101 has a mounting hole 1011, through which the adjusting rod 1072 extends out of the housing 101.

[0067] The adjusting nut 1073 is threadedly engaged with the adjusting rod 1072, and the adjusting nut 1073 is located on the outside of the housing 101. During the rotation of the adjusting nut 1073, since the adjusting rod 1072 cannot rotate with the adjusting nut 1073, the adjusting nut 1073 moves along the adjusting rod 1072; since the adjusting nut 1073 abuts against the housing 101, the adjusting rod 1072 moves along its axial direction, i.e., along the second direction. Because the adjusting rod 1072 is fixedly connected to the connecting seat 1071, and the connecting seat 1071 is fixedly connected to the clamping plate 105, the movement of the adjusting rod 1072 along the second direction simultaneously drives the clamping plate 105 to move along the second direction, thereby achieving the adjustment of the distance between the clamping plate 105 and the base plate 106 along the second direction.

[0068] It should be noted that the adjustment component 107 in this embodiment has a simple structure, and the adjustment nut 1073 is located on the outside of the housing 101, which facilitates operation by the operator. In addition, the adjustment rod 1072 extends out of the housing 101 through the mounting hole 1011, and the housing 101 can be used to limit and guide the movement of the adjustment rod 1072, ensuring the accuracy of the movement of the adjustment rod 1072.

[0069] like Figure 5 As shown, the connecting rod 108 includes: a first section 1081, a second section 1082, an intermediate section 1083, and a shoulder 1084.

[0070] The first segment 1081, the middle segment 1083, and the second segment 1082 are arranged sequentially along the second direction. Optionally, the first segment 1081, the middle segment 1083, and the second segment 1082 are integrally formed structures.

[0071] Shoulder 1084 is provided in the middle section 1083, and the diameter of shoulder 1084 is larger than the diameter of middle section 1083.

[0072] During the connection between the clamping plate 105 and the connecting rod 108, the second mounting hole 1052 of the clamping plate 105 is assembled to the middle section 1083 via the first section 1081, and abuts against one side of the shoulder 1084 for limitation. During the connection between the base plate 106 and the connecting rod 108, the third mounting hole 1063 of the base plate 106 is assembled to the middle section 1083 via the second section 1082, and abuts against the other side of the shoulder 1084 for limitation.

[0073] The shoulder 1084 is used to limit the distance between the base plate 106 and the clamping plate 105 in the second direction, so as to prevent the distance between the clamping plate 105 and the base plate 106 in the second direction from being too small, which would affect the movement of the insert plate 102 in the first direction.

[0074] In this embodiment, the first segment 1081 and the second segment 1082 are, but are not limited to, threaded segments. The first segment 1081 is connected to a first threaded component, which includes, but is not limited to, a nut. By abutting against the clamping plate 105 with the first threaded component, the clamping plate 105 is limited in the second direction under the action of the first threaded component and the shoulder 1084. The second segment 1082 is connected to a second threaded component, which includes, but is not limited to, a nut. By abutting against the base plate 106 with the second threaded component, the base plate 106 is limited in the second direction under the action of the second threaded component and the shoulder 1084.

[0075] Optionally, an elastic sealing ring is provided between the first threaded component and the clamping plate 105. The locking force of the first threaded component can be adjusted by using the elastic sealing ring, thereby adjusting the clamping force between the clamping plate 105 and the base plate 106, that is, achieving elastic clamping of the insert plate 102 by the base plate 106 and the clamping plate 105.

[0076] During the insertion of the insert plate 102 between the base plate 106 and the clamping plate 105, the clamping plate 105, under the action of the elastic sealing ring, has an elastic space along the second direction, thereby achieving elastic clamping of the insert plate 102 between the first end of the base plate 106 and the first end of the clamping plate 105. Furthermore, under the elastic action of the elastic sealing element, the insert plate 102 can achieve a seal between the base plate 106 and the clamping plate 105.

[0077] like Figure 6 As shown, the clamping plate 105 disclosed in this application embodiment is a rectangular frame. The upper end of the rectangular frame along the first direction has a first mounting hole 1051, and the lower end of the rectangular frame along the first direction has a second mounting hole 1052.

[0078] The first mounting hole 1051 is used to connect with the connecting seat 1071 of the adjusting assembly 107 via a threaded fastener. The second mounting hole 1052 is used to connect with the first section 1081 of the connecting rod 108.

[0079] The clamping plate 105 disclosed in this application embodiment is a frame structure, which allows the inlet of the base plate 106 to communicate with the discharge port of the housing 101 through the hollow position of the clamping plate 105. It is understood that the clamping plate 105 in this document includes, but is not limited to, a rectangular frame, and the space enclosed by the frame of the clamping plate 105 is opposite to the inlet of the base plate 106.

[0080] like Figure 7 As shown, the base plate 106 disclosed in this application embodiment has a first inlet 1061, a second inlet 1062 and a third mounting hole 1063.

[0081] The first inlet 1061 and the second inlet 1062 are arranged along a first direction. Optionally, the areas of the first inlet 1061 and the second inlet 1062 may be different; alternatively, the area of ​​the first inlet 1061 may be larger than the area of ​​the second inlet 1062. The first inlet 1061 is higher than the second inlet 1062 along the first direction to accommodate the distribution of materials in the direction of gravity.

[0082] During the movement of the insert plate 102 along the first direction, the opening degree of the first inlet 1061 and the second inlet 1062 can be adjusted. Optionally, the movement of the insert plate 102 can only realize the control of the opening and closing of the first inlet 1061 and the second inlet 1062. The control of the opening degree of the first inlet 1061 and the second inlet 1062 can be related to the stroke of the driver 103 and the start and stop position of the driver 103.

[0083] The third mounting hole 1063 is located at the lower end of the base plate 106 along the first direction and is used to connect with the second section 1082 of the connecting rod 108.

[0084] The shape and size of the base plate 106 in this application embodiment can be set according to different needs, and all are within the protection scope.

[0085] In some embodiments, at least one of the base plate 106 and clamping plate 105 of the slide valve 100 is provided with a discharge hole for preventing material sticking that extends in a second direction.

[0086] It should be noted that by setting a discharge hole, the material stuck between the base plate 106 and the clamping plate 105 can be discharged through the discharge hole, thereby reducing the situation of material jamming.

[0087] In addition, such as Figure 8 As shown in the figure, this application embodiment also discloses a feeder, including a hopper 201, a coarse feeding spiral channel 202, a fine feeding spiral channel 203, and a slide valve 100.

[0088] The hopper 201 includes, but is not limited to, a funnel-shaped structure, and contains materials to be conveyed.

[0089] The coarse batching spiral channel 202 is connected to the outlet of the silo 201, and the fine batching spiral channel 203 is also connected to the outlet of the silo 201. It is known that the pitch of the spiral blades in the coarse batching spiral channel 202 is greater than the pitch of the spiral blades in the fine batching spiral channel 203, and the size of the spiral blades in the coarse batching spiral channel 202 is greater than the size of the spiral blades in the fine batching spiral channel 203.

[0090] The outlets of the coarse feeding spiral channel 202 and the fine feeding spiral channel 203 are provided with slide gate valves 100. Optionally, the slide gate valve 100 is the slide gate valve 100 disclosed in the above embodiments. Therefore, the feeder using the slide gate valve 100 also has all the above-mentioned technical effects, which will not be repeated here.

[0091] During the connection between the coarse batching spiral channel 202 and the fine batching spiral channel 203 and the slide gate valve 100, the outlet of the coarse batching spiral channel 202 is connected to the first inlet 1061 of the slide gate valve 100, and the outlet of the fine batching spiral channel 203 is connected to the second inlet 1062 of the slide gate valve 100.

[0092] Using the above connection method, the amount of material conveyed by the coarse batching spiral channel 202 and the fine batching spiral channel 203 can be controlled during the movement of the slide plate 102 of the slide valve 100 along the first direction.

[0093] like Figure 9 As shown in the embodiments of this application, the feeder disclosed includes multiple hoppers 201 and a collector 300.

[0094] The discharge port of the slide valve 100 of the silo 201 is connected to the collector 300. The collector 300 is equipped with a weighing sensor, which can weigh the material in the collector 300.

[0095] Since the dimensions of the slide gate valve 100 disclosed in the embodiments of this application are small in the planes in the second and third directions, that is, the slide gate of the slide gate valve 100 is arranged along the first direction, the radial dimension of the slide gate valve 100 is small, which makes the radial structure of the slide gate valve 100 compact and helps to reduce the radial space occupied by the slide gate valve 100.

[0096] In some embodiments, multiple hoppers 201 can be connected to the collector 300 simultaneously. Optionally, the collector 300 has multiple material inlets along its circumference, and the discharge port of the gate valve 100 of the hopper 201 communicates with the material inlets. Because the radial dimension of the gate valve 100 is small, multiple hoppers 201 can be arranged circumferentially along the collector 300, which is beneficial for increasing the number of hoppers 201 communicating with the collector 300.

[0097] Optionally, the hopper 201 and the collector 300 are arranged in a tower configuration, meaning the feeder is a tower-type device. The tower configuration is as follows: the hopper 201 and the slide gate valve 100 are arranged along a first direction, and the hopper 201 and the slide gate valve 100 are radially offset; the slide gate valve 100 and the collector 300 are arranged along the first direction, such that the hopper 201 and the collector 300 are arranged along the first direction, and the hopper 201 and the collector 300 are offset along a second direction, such that the slide gate valve 100 is located below the funnel-shaped structure of the hopper 201.

[0098] Optionally, the collector 300 has a frustum-shaped structure, and the diameter of the end of the collector 300 near the slide gate valve 100 is larger than the diameter of the end away from the slide gate valve 100, and the upper surface of the collector 300 is connected to the slide gate valve 100.

[0099] The tower-style arrangement makes full use of the space formed by the lower cone of the silo, allowing more silos to be transported into a smaller volume weighing scale.

[0100] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
