Description

Technical fields:

[0001] This utility model belongs to the field of deep coal processing, and in particular relates to a slurry pump hose conveying buffer device. Background technology:

[0002] Slurry pumps are widely used in industries such as mining, metallurgy, power, and coal. The core function of slurry pumps is to transport slurry media containing solid particles through centrifugal force.

[0003] Taking the coal washing system of a coal preparation plant as an example, coal slurry needs to be injected into a matching rubber hose via a slurry pump, and then transported to a sedimentation tank or thickening tank for solid-liquid separation. In actual production, because the slurry pump imparts potential energy to the coal slurry, and there is no buffer structure in the coal slurry conveying system, the direct impact force of the coal slurry on the bends of the rubber hose during high flow is relatively large. This leads to frequent cracking and leakage accidents at the bends of the coal slurry conveying rubber hose, which not only pollutes the production site environment and causes production system shutdowns, but also, in severe cases, affects the normal, safe and stable operation of the coal washing system. Summary of the Invention:

[0004] The purpose of this utility model is to provide a slurry pump hose conveying buffer device, which overcomes the shortcomings of the prior art and effectively solves the existing problem of damage caused by direct impact of coal slurry on conveying rubber hoses.

[0005] The present invention relates to a slurry pump hose conveying buffer device, comprising a buffer box, an inlet pipe connected to one side of the buffer box, a discharge pipe connected to the outer end of the front of the buffer box, a plurality of support rods installed side by side and at equal intervals in the inner cavity of the buffer box, a plurality of sleeves fitted at equal intervals along the length direction on the support rods, the sleeves being rotatably connected to the support rods, a buffer rod being connected to the sleeves, and a limit protrusion provided at both ends of the sleeves, the limit protrusions being installed on the outer circumferential surface of the support rods.

[0006] Furthermore, the two adjacent buffer bars are staggered with each other.

[0007] Furthermore, an L-shaped pad is installed on the bottom wall of the buffer box.

[0008] Furthermore, an arc-shaped support plate is provided at the outer end of both the feed pipe and the discharge pipe, and a bracket is installed on the bottom wall of the arc-shaped support plate, with the bottom end of the bracket being fixedly connected to the top wall of the L-shaped pad.

[0009] Furthermore, the arc-shaped support plates are all coaxial with the feed pipe and the discharge pipe.

[0010] Furthermore, bolt connection holes are provided at each apex corner of the L-shaped pad.

[0011] The beneficial effects of this utility model are as follows: by setting a buffer box at the bend of the slurry pump conveying hose, the impact force brought by the coal slurry can be buffered and absorbed, thereby protecting the slurry pump conveying hose from damage and avoiding cracking and leakage accidents, so that the production system can be installed and operated continuously and stably.

Detailed implementation method:

[0017] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:

[0018] like Figures 1 to 4 As shown, a slurry pump hose conveying buffer device includes a buffer tank 1. A feed pipe 2 is connected to one side of the buffer tank 1, and a discharge pipe 3 is connected to the outer end of the front of the buffer tank 1. Several support rods 4 are installed side-by-side at equal intervals inside the buffer tank 1. Several sleeves 5 are fitted onto the support rods 4 at equal intervals along their length. The sleeves 5 are rotatably connected to the support rods 4. Buffer rods 6 are connected to the sleeves 5. Limiting protrusions 7 are provided at both ends of the sleeves 5. 7 is installed on the outer circumferential surface of the support rod 4; the two adjacent buffer rods 6 are staggered; an L-shaped pad 8 is installed on the bottom wall of the buffer box 1; an arc-shaped support plate 9 is provided at the outer end of the feed pipe 2 and the discharge pipe 3, and a bracket 10 is installed on the bottom wall of the arc-shaped support plate 9, the bottom end of the bracket 10 is fixedly connected to the top wall of the L-shaped pad 8; the arc-shaped support plates 9 are all coaxial with the feed pipe 2 and the discharge pipe 3; a bolt connection hole 11 is opened at each apex corner of the L-shaped pad 8.

[0019] Specifically, the buffer box 1 installed at the bend of the slurry pump delivery hose can buffer and absorb the impact force brought by the coal slurry, thereby protecting the slurry pump delivery hose from damage.

[0020] In actual use, a buffer box 1 is set at the bend in the slurry pump conveying hose laying route, and expansion bolts are inserted into the bolt connection hole 11. The L-shaped pad 8 and the buffer box 1 are fixed to the ground. At this time, the two sections of rubber hose are flanged to the feed pipe 2 and the discharge pipe 3 respectively. When the coal slurry enters the buffer box 1 through the feed pipe 2, it comes into contact with several metal buffer rods 6 that fall naturally. After the buffer rods 6 absorb the impact force of the coal slurry, they swing on the support rod 4 together with the sleeve 5. The limiting protrusion 7 prevents the sleeve 5 from shifting. During the continuous and repeated swinging of the buffer rods 6, part of the impact force of the coal slurry is absorbed and unloaded, thereby slowing down the original impact force of the coal slurry and protecting the rubber hose from being damaged by the impact.

[0021] In the above process, several support rods 4 arranged side by side and at equal intervals form a multi-layered buffer absorption barrier with several buffer rods 6 connected to them. As the coal slurry flows through the buffer rods 6 in sequence, its impact force is also buffered and absorbed step by step, further reducing the original impact force of the coal slurry. The two adjacent buffer rods 6 are staggered, so that when the buffer rods 6 are shaken by the impact force, the two adjacent buffer rods 6 will not collide with each other, and at the same time, they can fill the gaps generated between the buffer rods 6, so that the impact force of the coal slurry can be further buffered and absorbed evenly. The arc-shaped support plate 9 coaxially set at the outer end of the feed pipe 2 and the discharge pipe 3 can not only lift the end of the rubber hose connected to it, which facilitates the quick connection between the pipes, but also alleviate the slope difference generated after the rubber hose is connected to the feed pipe 2 and the discharge pipe 3, reduce the occurrence of the rubber hose bending point, further reduce the impact force of the coal slurry on the rubber hose, and protect the rubber hose from impact damage.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
