Description

Technical Field

[0001] This utility model relates to the field of baffle technology, and in particular to a baffle for environmental protection equipment. Background Technology

[0002] With increasing public awareness of environmental protection and higher requirements for waste disposal, environmental protection facilities such as waste disposal equipment are becoming increasingly important in modern society.

[0003] However, in practice, a common problem is the insufficient sealing performance of the feed inlets of these devices. Many existing environmental protection devices have not fully considered the effective sealing of the feed inlets during their design phase, especially during dynamic feeding. Since efficient waste treatment usually requires a relatively closed environment to ensure treatment efficiency and effectiveness, any degree of air leakage may lead to gas escape, odor diffusion and release of harmful substances, which in turn will have an adverse impact on the surrounding environment and the waste treatment effect. Utility Model Content

[0004] The purpose of this utility model is to provide a baffle for environmental protection equipment in order to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A baffle for environmental protection equipment includes a housing with an inlet and an inlet baffle. An electric telescopic rod is mounted on the housing. A fixed plate is fixedly connected to the inlet baffle. The free end of the electric telescopic rod and the fixed plate are connected by a linkage mechanism for opening and closing the inlet baffle. An annular groove is formed at the bottom of the inlet baffle. A plurality of first conical rods penetrating the annular groove are slidably arranged on the inlet baffle along its axial direction. Second conical rods are slidably arranged in a second guide groove along the radial direction of the inlet baffle. The conical surfaces of the two sets of conical rods are tangent. A ring bracket that mates with the annular groove is fixedly connected to the free end of the first conical rod. A sealing ring is adhered to the bottom of the ring bracket. A compression spring sleeved on the inner first conical rod is arranged between the ring bracket and the annular groove.

[0007] As a further description of the above technical solution:

[0008] The feed baffle is provided with a plurality of first guide grooves for accommodating the first cone rods, and a plurality of second guide grooves for accommodating the second cone rods. One end of the first guide groove and the second guide groove are connected together, and limiting rings that transitionally cooperate with the guide grooves are fixedly connected to the two sets of cone rods respectively.

[0009] As a further description of the above technical solution:

[0010] The feed baffle is an inverted frustum-shaped structure, and the feed inlet is a conical stepped hole that mates with the feed baffle. The sealing ring mates with the stepped surface of the stepped hole.

[0011] As a further description of the above technical solution:

[0012] The free end of the second cone rod is a hemispherical structure, and the spherical surface of the free end of the second cone rod is tangent to the cone surface of the feed inlet.

[0013] As a further description of the above technical solution:

[0014] The linkage mechanism includes a first link, a second link, a third link, and a fourth link. A convex plate is fixedly connected to the middle of the first link. The free end of the electric telescopic rod is rotatably connected to the convex plate. One end of the first link is rotatably connected to one end of the second link. The free end of the second link is rotatably connected to one end of the fixed plate. The other end of the fixed plate is rotatably connected to one end of the fourth link. The free end of the fourth link is rotatably connected to one end of the third link. The middle parts of the second and fourth links are rotatably engaged.

[0015] As a further description of the above technical solution:

[0016] The linkage mechanism further includes a first fixed seat, a second fixed seat, and a third fixed seat. The three sets of fixed seats are fixedly connected to the equipment housing and are arranged in the radial direction of the feed baffle. The fixed end of the electric telescopic rod is rotatably engaged with the first fixed seat, the free end of the first connecting rod is rotatably engaged with the second fixed seat, and the free end of the third connecting rod is rotatably engaged with the third fixed seat.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, during the closing process of the feed baffle and the feed inlet, the sealing ring descends to make contact with the stepped surface of the feed inlet, improving the sealing performance between the feed baffle and the feed inlet. This allows the waste to be processed in a relatively closed environment, ensuring processing efficiency and effectiveness, and preventing gas leakage, odor diffusion, and release of harmful substances. Conversely, when the feed baffle disengages from the feed inlet, the sealing ring returns to the annular groove under the elastic force of the compression spring. This protects the sealing ring when it is not in use, reducing its contact with impurities in the external environment, reducing wear, and increasing the service life of the sealing ring.

[0019] 2. In this utility model, the dynamic opening and closing of the feed inlet is realized through the extension and retraction of the electric telescopic rod in conjunction with the operation of the linkage mechanism, thereby supporting the waste treatment equipment to carry out efficient dynamic feeding operations. This not only ensures the convenience and accuracy of operation, but also improves the safety and sealing effect of the waste treatment equipment. Attached Figure Description

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5This utility model provides a technical solution: a baffle for environmental protection equipment, including a housing 1, such as a waste treatment equipment housing, with an inlet 101 on the housing 1, an inlet baffle 11 mounted on the inlet 101, an electric telescopic rod 3 installed on the housing 1, and a fixed plate 10 fixedly connected to the inlet baffle 11. The free end of the electric telescopic rod 3 and the fixed plate 10 are connected by a linkage mechanism for opening and closing the inlet baffle 11. The linkage mechanism includes a first fixed seat 2, a second fixed seat 4, a third fixed seat 5, a first connecting rod 6, a second connecting rod 7, a third connecting rod 8, and a fourth connecting rod 9. The three sets of fixed seats are arranged at the inlet... In the radial direction of the baffle 11, a protruding plate 12 is fixedly connected to the middle of the first connecting rod 6. The free end of the electric telescopic rod 3 is rotatably connected to the protruding plate 12. One end of the first connecting rod 6 is rotatably connected to one end of the second connecting rod 7. The free end of the second connecting rod 7 is rotatably connected to one end of the fixed plate 10. The other end of the fixed plate 10 is rotatably connected to one end of the fourth connecting rod 9. The free end of the fourth connecting rod 9 is rotatably connected to one end of the third connecting rod 8. The middle parts of the second connecting rod 7 and the fourth connecting rod 9 are rotatably engaged. The fixed end of the electric telescopic rod 3 is rotatably engaged with the first fixed seat 2. The free end of the first connecting rod 6 is rotatably engaged with the second fixed seat 4. The free end of the third connecting rod 8 is rotatably engaged with the third fixed seat 5. By retracting the free end of the electric telescopic rod 3, the protruding plate 12 is driven to swing the first connecting rod 6 in the opposite direction. Then, the movement of the first connecting rod 6 will drive the second connecting rod 7 to the right (according to...). Figure 1 The first link 7 pulls the feed baffle 11 away from the feed inlet 101. Subsequently, the movement of the second link 7 will cause the third link 8 to swing in the opposite direction. In turn, the movement of the third link 8 will drive the fourth link 9 to pull the feed baffle 11 further to the right, ensuring that it is completely away from the feed inlet 101, thus opening the feed inlet 101. Conversely, when it is necessary to close the feed inlet 101, the free end of the electric telescopic rod 3 will extend. This action drives the above-mentioned linkage mechanism in the opposite direction, so that the feed baffle 11 gradually approaches and finally closes tightly with the feed inlet 101, completing the closing process of the feed inlet 101. Through the extension and retraction of the electric telescopic rod 3, in conjunction with the operation of the linkage mechanism, the dynamic opening and closing of the feed inlet 101 is realized, thereby supporting the waste treatment equipment to carry out efficient dynamic feeding operations. This not only ensures the convenience and accuracy of operation, but also improves the safety and sealing effect of the waste treatment equipment.

[0029] Specifically, such as Figure 2-5As shown, the feed baffle 11 is an inverted frustum-shaped structure. The feed inlet 101 is a conical stepped hole that mates with the feed baffle 11. The sealing ring 18 mates with the stepped surface of the stepped hole. An annular groove 1103 is provided at the bottom of the feed baffle 11. Several first guide grooves 1101 communicating with the annular groove 1103 are provided on the feed baffle 11 along its axial direction. Several second guide grooves 1102 communicating with the first guide grooves 1101 are provided on the side of the feed baffle 11 along its radial direction. The inner ends of the first guide grooves 1101 and the second guide grooves 1102 are connected. A first conical rod 13 is slidably arranged in the first guide groove 1101. A second cone rod 14 is slidably arranged inside the groove 1102. Limiting rings 15 that transition with the guide groove are fixedly connected to the two sets of cone rods respectively. The conical surfaces of the two sets of cone rods are tangent to each other. The free end of the second cone rod 14 is a hemispherical structure. The spherical surface of the free end of the second cone rod 14 is tangent to the conical surface of the feed inlet 101. The free end of the first cone rod 13 is fixedly connected to a ring bracket 17 that cooperates with the annular groove 1103. A sealing ring 18 is bonded to the bottom of the ring bracket 17. A compression spring 16 is arranged between the ring bracket 17 and the annular groove 1103 and is sleeved on the inner first cone rod 13. The two ends of the compression spring 16 are fixedly connected to the annular groove 1103 and the ring bracket 17 respectively. During the closing process between the feed baffle 11 and the feed inlet 101, the second cone rod 14 is pushed into the second guide groove 1102 by the action of the cone surface of the feed inlet 101, and the cone surface of the first cone rod 13 is pushed out of the first guide groove 1101 by the action of the cone surface of the second cone rod 14. The compression spring 16 is stretched, and the first cone rod 13 pushes the ring bracket 17 and the sealing ring 18 down to press against the stepped surface of the feed inlet 101, thereby improving the sealing performance between the feed baffle 11 and the feed inlet 101. This allows the waste to be processed in a relatively closed environment, ensuring processing efficiency and effectiveness, and preventing gas leakage, odor diffusion, and release of harmful substances. Conversely, when the feed baffle 11 disengages from the feed inlet 101, the sealing ring 18 returns to the annular groove 1103 under the elastic force of the compression spring 16. This protects the sealing ring 18 when it is not in use, reducing its contact with impurities in the external environment, reducing wear, and increasing the service life of the sealing ring 18.

[0030] Working principle: In use, the free end of the electric telescopic rod 3 retracts, driving the convex plate 12 to cause the first connecting rod 6 to swing in the opposite direction. Then, the movement of the first connecting rod 6 will cause the second connecting rod 7 to move to the right (according to...). Figure 1The first link 7 pulls the feed baffle 11 away from the feed inlet 101. Then, the movement of the second link 7 will cause the third link 8 to swing in the opposite direction. In turn, the movement of the third link 8 will drive the fourth link 9 to pull the feed baffle 11 further to the right, ensuring that it is completely away from the feed inlet 101, thus opening the feed inlet 101. Conversely, when it is necessary to close the feed inlet 101, the free end of the electric telescopic rod 3 will extend. This action drives the above-mentioned linkage mechanism in the opposite direction, so that the feed baffle 11 gradually approaches and finally closes tightly with the feed inlet 101, completing the closing process of the feed inlet 101. Through the extension and retraction of the electric telescopic rod 3, in conjunction with the operation of the linkage mechanism, the dynamic opening and closing of the feed inlet 101 is realized, thereby supporting the waste treatment equipment to carry out efficient dynamic feeding operations. This not only ensures the convenience and accuracy of operation, but also improves the safety and sealing effect of the waste treatment equipment.

[0031] During the process of the feed baffle 11 closing the feed inlet 101, the second cone rod 14 is pushed into the second guide groove 1102 by the action of the cone surface of the feed inlet 101, and the cone surface of the first cone rod 13 is pushed out of the first guide groove 1101 by the action of the cone surface of the second cone rod 14. The compression spring 16 is stretched, and the first cone rod 13 pushes the ring bracket 17 and the sealing ring 18 down to press against the stepped surface of the feed inlet 101, thereby improving the connection and sealing between the feed baffle 11 and the feed inlet 101. This allows the waste to be processed in a relatively closed environment, ensuring processing efficiency and effectiveness, and preventing gas leakage, odor diffusion, and release of harmful substances. Conversely, during the process of the feed baffle 11 opening the feed inlet 101, the sealing ring 18 returns to the annular groove 1103 under the elastic force of the compression spring 16. This protects the sealing ring 18 when it is not in use, reducing its contact with impurities in the external environment, reducing wear, and increasing the service life of the sealing ring 18.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
