Description

Technical Field

[0001] The utility model belongs to the technical field of wear-resistant rings, and particularly relates to an elastic dust-proof and wear-resistant ring for a particle forming device. Background Art

[0002] In the biomass particle industry, as one of the most important devices, the horizontal particle forming device has a horizontal feeding method for raw materials. Horizontally, there is a static door cover, and a screw feeder (referred to as forced feeding) is installed. The forced feeding pushes the raw materials into a rotating transition cover (referred to as a die cover) and a mold for raw material extrusion and particle forming. A wear-resistant ring is usually used for sealing between the door cover and the rotating die cover.

[0003] In the existing wear-resistant rings, during the raw material transportation process, there must be a rotating gap between the static door cover and the rotating die cover in the particle forming device. However, the existing wear-resistant rings cannot fully seal the gap, resulting in the leakage of raw material dust from the gap, affecting the surrounding environment and the quality of the particles.

[0004] Therefore, we provide an elastic dust-proof and wear-resistant ring for a particle forming device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an aluminum single plate and an aluminum single plate fixing structure, which have the advantage of good sealing effect, and solve the problem that the existing aluminum single plate cannot seal the gap between the door cover and the rotating die cover.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model provides an elastic dust-proof and wear-resistant ring for a particle forming device, which comprises a bracket. A first placement groove and a second placement groove are formed on the back surface of the bracket. A first graphite packing is fixedly connected inside the first placement groove, and a second graphite packing is fixedly connected inside the second placement groove. A third graphite packing is fixedly connected inside the bracket. A threaded pin is fixedly connected to the front surface of the bracket. A nut is threadedly connected to one side of the surface of the threaded pin, and a spring is sleeved on the surface of the threaded pin.

[0008] The utility model is further arranged such that the diameter of the second placement groove is smaller than that of the first placement groove, and the groove shapes inside the first placement groove and the second placement groove are both trapezoidal.

[0009] The utility model is further arranged such that the number of the threaded pins is eight, and they are symmetrically fixed on the back surface of the bracket.

[0010] The utility model is further arranged such that the number of the nuts is eight, and they are all threadedly connected to one side of the surface of the threaded pin.

[0011] The present utility model is further configured such that the number of the springs is eight, and both ends thereof are fixedly connected to the front surface of the nut and the back surface of the bracket respectively.

[0012] The present utility model is further configured such that a sealing groove is provided at the rear side of the inner cavity of the bracket, and the third graphite packing is fixedly connected inside the sealing groove.

[0013] The present utility model has the following beneficial effects:

[0014] Through the arrangement of the nut and the threaded pin, the wear-resistant ring can be fixed on the door cover of the pellet forming device. The spring can provide certain elasticity when installing the threaded pin, so that the threaded pin can be compensated when stressed or the temperature changes. This helps to maintain the appropriate tightening force or clearance between the threaded pin and the component it is fixed to, ensuring the sealing performance during use. Through the arrangement of the first graphite packing and the second graphite packing, the gap at the end face of the die pressing cover can be sealed. Through the arrangement of the third graphite packing, the gap in the diameter direction of the forced feeding can be sealed.

[0015] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present invention will be described in conjunction with the attached drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Specific Embodiment 1

[0026] Please refer to Figures 1-6 , the present invention is an elastic dust-proof and wear-resistant ring for a particle forming device, including a bracket 1. A first placement groove 2 and a second placement groove 3 are opened on the back surface of the bracket 1. A first graphite packing 4 is fixedly connected inside the first placement groove 2, a second graphite packing 5 is fixedly connected inside the second placement groove 3, a third graphite packing 6 is fixedly connected inside the bracket 1, a threaded pin 7 is fixedly connected to the front surface of the bracket 1, a nut 8 is threadedly connected to one side of the surface of the threaded pin 7, and a spring 9 is sleeved on the surface of the threaded pin 7.

[0027] Specifically: The first placement groove 2 has the largest diameter and is opened on the outermost side of the back surface of the bracket 1, while the diameter of the second placement groove 3 is smaller than that of the first placement groove 2. It is opened on the back surface of the bracket 1 and is adjacent to the first placement groove 2. The number of nuts 8 is eight, which can facilitate subsequent installation work. The number of springs 9 is also eight, and they are symmetrically sleeved on the surface of the threaded pin 7. Specific Embodiment 2

[0029] Please refer to Figures 1-6 , on the basis of Specific Embodiment 1, the diameter of the second placement groove 3 is smaller than that of the first placement groove 2. The groove shapes inside the first placement groove 2 and the second placement groove 3 are both trapezoidal. The number of threaded pins 7 is eight, and they are symmetrically fixed on the back surface of the bracket 1. The number of nuts 8 is eight, and they are all threadedly connected to one side of the surface of the threaded pin 7. The number of springs 9 is eight, and both ends thereof are fixedly connected to the front surface of the nut 8 and the back surface of the bracket 1 respectively. A sealing groove 10 is opened at the rear side of the inner cavity of the bracket 1, and the third graphite packing 6 is fixedly connected inside the sealing groove 10.

[0030] Specifically: The interiors of the first placement groove 2 and the second placement groove 3 are both trapezoidal, which can facilitate the fixation of the first graphite packing 4 and the second graphite packing 5. The threaded pin 7 can fix the wear-resistant ring on the door cover. The nuts 8 are all threadedly connected to the front side of the surface of the threaded pin 7. The spring 9 can fill the gap between the die pressing cover and the door cover through its own elasticity. The sealing groove 10 is opened at the rear side of the inner cavity of the bracket 1, which can facilitate the installation of the third graphite plate.

[0031] The working principle of the present utility model is as follows: When it is necessary to seal the gap, the user sleevs the inner hole of the bracket 1 on the surface of the forced feeding port, then inserts the threaded pin 7 into the door cover, and then rotates the nut 8 to fix it, so as to complete the installation work. Then, during the process of transporting raw materials, the spring 9 will maintain an appropriate tightening force or gap between the die pressing cover and the door cover through its own elasticity to ensure sufficient sealing performance. The first graphite packing 4 and the second graphite packing 5 can seal the gap at the end face of the die pressing cover, and the third graphite packing 6 can seal the gap in the diameter direction of the forced feeding port, so as to fully seal the gap between the door cover and the rotating die pressing cover.
