Description

Technical Field

[0001] The utility model belongs to the technical field of mine boot washing machines, and particularly relates to a air knife structure. Background Technique

[0002] The sole of a mining boot is thick, with thick and deep patterns, and usually has good anti-slip and wear-resistant properties. The boot tube of a mining boot usually reaches the knees, is thicker than ordinary rain boots, and plays a protective role for the calves. It is a rubber surface protective boot suitable for miners to wear underground, which can ensure the feet of miners are clean and dry.

[0003] Chinese Patent with application number CN202322259678.9 discloses a multi-channel mine boot washing machine, which includes a water tank, a grille plate, N supports, a boot tube cleaning mechanism and a boot sole cleaning mechanism. The inlet end of the grille plate is provided with a grille-shaped pedal, and a vibrator is installed at the bottom of the grille-shaped pedal. The N supports are divided into N - 1 channels along the width direction of the grille plate for only single mining boots to pass through. On one side near the outlet end between each support and the grille plate, a boot tube air drying mechanism is installed. The air drying mechanism includes a number of vertical air pipes arranged at intervals. Each vertical air pipe is fixedly connected between the corresponding support and the grille plate, and a number of jet nozzles are provided on the pipe wall of each vertical air pipe facing the corresponding channel.

[0004] However, the air drying mechanism in the above prior art uses the method of installing jet nozzles on the air pipe to jet air for air drying. The air outlet efficiency of the air drying mechanism is low, resulting in low air drying efficiency and poor air drying effect. Therefore, an air knife structure is improved and designed. Content of the Utility Model

[0005] In view of the above deficiencies existing in the prior art, the utility model provides an air knife structure to solve the problems in the above background technique.

[0006] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0007] An air knife structure includes an air inlet pipe connected to an air source and an air knife structure installed on the air inlet pipe. The air knife structure includes a connecting pipe, and a plurality of air outlet notches are opened along the length direction of the connecting pipe. Side plates are arranged on the left and right sides of the air outlet notches, and the two side plates are fixedly connected to the outer wall of the connecting pipe. The upper and lower ends of the side plates are hermetically connected with cover plates, and a gap is left between the ends of the two side plates away from the connecting pipe to form an air outlet of the air knife.

[0008] By adopting the above structural design, the air knife structure includes an air inlet pipe connected to an air source and an air knife structure installed on the air inlet pipe. The air knife structure includes a connecting pipe, and a plurality of air outlet gaps are formed in the connecting pipe. Side plates are arranged on the left and right sides of the air outlet gaps. The high-pressure air flow of the air source is transported to the connecting pipe through the air inlet pipe and ejected from the air outlet gaps, entering the buffer chamber formed by the two side plates and the two cover plates. Since there is a gap between the ends of the two side plates far from the connecting pipe, a slender air knife air outlet is formed. Finally, the high-pressure air flow is ejected from the gap, and the high-pressure air is squeezed into the shape of an air knife, and at the same time drives the air flow on both sides of the air knife opening and sprays forward to clean the remaining water droplets after the boots are washed. By setting a slender air knife air outlet to replace the nozzle in the prior art, the air outlet efficiency of this air knife structure is higher, and the air drying effect of the mining boots is better.

[0009] Further, the ends of the two side plates close to the connecting pipe are far away from each other, and the ends of the two side plates far from the connecting pipe are close to each other.

[0010] Further, a flow guide plate is arranged along the length direction of the end of the side plate far from the connecting pipe, and the air flow is ejected from the air outlet gap and blown out between the two flow guide plates.

[0011] Further, it further includes a baffle plate. The baffle plate is arranged in parallel in front of the connecting pipe. A notch is formed in the baffle plate along its height direction. The flow guide plate is located in the notch, and a side baffle plate is arranged on the edge of the notch. The side baffle plate is fixedly connected to the side plate.

[0012] Further, the number of the air knife structures is three. Among them, two air knife structures are symmetrically arranged above the air inlet pipe, and the other air knife structure is arranged on the air inlet pipe between the two air knife structures.

[0013] By adopting the above structural design, the number of the air knife structures is set to three. One is horizontally arranged at the bottom, and the other two are symmetrically arranged above the air inlet pipe, which can dry the mining boots more comprehensively.

[0014] Further, the side plates are connected to the connecting pipe, the cover plates and the side baffle plates by welding.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The air knife structure includes an air inlet pipe connected to an air source and an air knife structure installed on the air inlet pipe. The air knife structure includes a connecting pipe, and a plurality of air outlet notches are formed in the connecting pipe. Side plates are arranged on the left and right sides of the air outlet notches. The high-pressure air flow of the air source is transported to the connecting pipe through the air inlet pipe and ejected from the air outlet notches, entering the buffer chamber formed by the two side plates and two cover plates. Since there is a gap between the ends of the two side plates far from the connecting pipe, a slender air knife air outlet is formed. Finally, the high-pressure air flow is ejected from the gap, and the high-pressure air is squeezed into the shape of an air knife. At the same time, the air flow on both sides of the air knife opening is driven and ejected forward to clean the remaining water droplets after the boots are washed. By setting a slender air knife air outlet to replace the nozzle in the prior art, the air outlet efficiency of this air knife structure is higher, and the air drying effect of the mining boots is better.

[0028] Embodiment 1:

[0029] As Figures 1-5 shown, the present utility model. Specifically, a wind knife structure includes an air inlet pipe 1 connected to an air source and a wind knife structure 2 installed on the air inlet pipe 1. The wind knife structure 2 includes a connecting pipe 21. A plurality of air outlet notches 211 are formed along the length direction of the connecting pipe 21. Side plates 22 are arranged on the left and right sides of the air outlet notches 211. The two side plates 22 are fixedly connected to the outer wall of the connecting pipe 21. The upper and lower ends of the side plates 22 are hermetically connected with cover plates 212. A gap is left between the ends of the two side plates 22 away from the connecting pipe 21 to form the air outlet of the wind knife. By adopting the above structural design, the wind knife structure includes an air inlet pipe 1 connected to an air source and a wind knife structure 2 installed on the air inlet pipe 1. Among them, the wind knife structure 2 includes a connecting pipe 21. A plurality of air outlet notches 211 are formed on the connecting pipe 21. Side plates 22 are arranged on the left and right sides of the air outlet notches 211. The high-pressure air flow of the air source is transported to the connecting pipe 21 through the air inlet pipe 1 and ejected from the air outlet notches 211 into the buffer chamber formed by the two side plates 22 and the two cover plates 212. Since a gap is left between the ends of the two side plates 22 away from the connecting pipe 21, a slender air outlet of the wind knife is formed. Finally, the high-pressure air flow is ejected from the gap, and the high-pressure air is squeezed into the shape of a wind knife, and at the same time drives the air flow on both sides of the wind knife opening and sprays forward to clean the remaining water droplets after the boots are washed. The wind knife structure 2 replaces the nozzle in the prior art by setting a slender air outlet of the wind knife, and its air outlet efficiency is higher, and the air drying effect of the mining boots is better.

[0030] In this embodiment, one ends of the two side plates 22 close to the connecting pipe 21 are away from each other, and one ends of the two side plates 22 away from the connecting pipe 21 are close to each other. A flow guide plate 221 is arranged along the length direction at one end of the side plate 22 away from the connecting pipe 21. Airflow ejects from the air outlet notch 211 and blows out between the two flow guide plates 221.

[0031] In this embodiment, it further includes a baffle plate 23. The baffle plate 23 is arranged in parallel in front of the connecting pipe 21. A notch 231 is formed in the baffle plate 23 along its height direction. The flow guide plate 221 is located in the notch 231. A side baffle plate 24 is arranged on the edge of the notch 231. The side baffle plate 24 is fixedly connected to the side plate 22.

[0032] In this embodiment, the number of the air knife structures 2 is three. Two of the air knife structures 2 are symmetrically arranged above the air inlet pipe 1, and the other air knife structure 2 is arranged on the air inlet pipe 1 between the two air knife structures 2. By adopting the above structural design, the number of the air knife structures 2 is set to three, one of which is horizontally arranged at the bottom and the other two are symmetrically arranged above the air inlet pipe 1, so as to be able to dry the mining boots more comprehensively. The side plate 22, the connecting pipe 21, the cover plate 212 and the side baffle plate 24 are connected by welding.

[0033] Working principle: Connect the air inlet pipe 1 with a vortex blower. The high-pressure air flow of the air source is transported to the connecting pipe 21 through the air inlet pipe 1, ejects from the air outlet notch 211, and enters the buffer chamber surrounded by the two side plates 22 and the two cover plates 212. Since there is a gap between one ends of the two side plates 22 away from the connecting pipe 21, a slender air knife air outlet is formed. Finally, the high-pressure air flow ejects from the gap, and the high-pressure air is squeezed into the shape of an air knife, and at the same time drives the air flow on both sides of the air knife opening to eject forward, so as to clean the remaining water droplets after the boots are washed. The air knife structure 2 replaces the nozzle in the prior art by arranging a slender air knife air outlet, and its air outlet efficiency is higher, and the drying effect of the mining boots is better.
