Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of air curtain equipment, in particular to an air curtain structure with nozzles convenient to replace. BACKGROUND

[0002] The resin sand flow line environmental protection air curtain is an environmental protection equipment applied to the resin sand production flow line. It mainly utilizes high-speed airflow to form an air screen similar to a curtain, limits dust and other pollutants in the resin sand treatment process within a certain range, and prevents them from spreading to the surrounding environment. The existing resin sand flow line environmental protection air curtain has obvious defects. The nozzles are subjected to continuous impact of high-speed airflow, frequent friction of resin sand particles and possible chemical substance erosion in the resin sand production environment, and are prone to wear and blockage. The nozzles are mostly closely connected with the main structure of the air curtain, such as welding or complex embedded installation.

[0003] When the nozzles fail, the conventional response is to suspend the entire resin sand flow line operation and arrange professional technicians to handle it. The technicians often need to spend a lot of time to disassemble the surrounding related components and connect the pipelines before they can access the faulty nozzles, and then perform replacement or cleaning operations. This method causes the production line to be shut down for a long time, greatly reduces the production efficiency and increases the time cost of the enterprise, so a new structure is needed to solve the above technical problems.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0020] Please refer to Figs. 1 to 3 The present application provides a technical solution: a wind curtain structure with a nozzle convenient to replace, comprising: a wind curtain assembly and a blowing assembly, the blowing assembly for outputting a wind curtain is installed inside the wind curtain assembly, the wind curtain assembly comprises: a shell 100 and a bottom shell 110, the bottom shell 110 is fixed on the lower side surface of the shell 100 through a clamping block 120 and a hand screw bolt 121, a plurality of air outlet holes 111 for air outlet are formed on the surface of the bottom shell 110, the blowing assembly comprises: a blower 200 and an air outlet pipe 220, the air outlet pipe 220 is installed inside the shell 100, the blower 200 is installed on the outer surface of the shell 100 through an air inlet pipe 210, the air outlet pipe 220 is in a rectangular structure, a plurality of mounting pipes 230 are installed on the outer surface of the air outlet pipe 220, air outlet nozzles 240 are sealingly connected inside the mounting pipes 230, and a plurality of reinforced fans 250 are installed on the inner surface of the air outlet pipe 220.

[0021] Please refer to Figs. 1 to 3 As a first embodiment of the present application: the lower side surface of the shell 100 is designed as an opening, one fixing groove is symmetrically formed on the left side surface and the right side surface of the shell 100 respectively, the structure of the fixing groove is matched with the structure of the clamping block 120, and threaded holes are formed on the surfaces of the fixing groove and the clamping block 120;

[0022] Two clamping blocks 120 are integrally formed on the left side edge and the right side edge of the upper side surface of the bottom shell 110 respectively, the number and position of the clamping blocks 120 are matched with the number and position of the fixing grooves, and the bottom shell 110 is fixed on the opening of the lower side surface of the shell 100 through the clamping blocks 120, the fixing grooves and the hand screw bolt 121;

[0023] In use, the user first installs the air curtain assembly in the position to be installed through the fixing bolt, and after the air curtain assembly is installed, the bottom shell 110 of the air curtain assembly faces downward, so that a gap is formed between the bottom shell 110 of the air curtain assembly and the ground, and the gap is the interval for the air curtain (the number, position and height of the installation need to be selected according to the actual situation, and details are not described here). Since the air curtain assembly is used in the working environment of the resin sand flow line, the blowing part of the air curtain assembly may fail or be blocked due to long-term operation or the entry of resin sand particles. At this time, the user can rotate the hand screw bolt 121 (the butterfly bolt) to release the clamping block 120 from the restraint, so as to separate the bottom shell 110 from the shell 100. After the bottom shell 110 is separated from the shell 100, the threaded air outlet nozzle 240 inside the air outlet assembly can be replaced. At this time, the bottom shell 110 fixed by the clamping block 120 is matched with the threaded air outlet nozzle 240, so that the disassembly and installation without using work are realized. The fixing mode of the clamping block 120 and the hand screw bolt 121 makes the disassembly of the bottom shell 110 very convenient. When the blowing assembly needs to be checked, repaired or replaced with the air outlet nozzle 240, the worker can simply unscrew the hand screw bolt 121 and then remove the bottom shell 110 to quickly access the internal blowing assembly, greatly shortening the repair time and reducing the impact of equipment downtime on production.

[0024] Please refer to Figs. 1 to 3 , as a second embodiment of the present application: the lower surface of the bottom shell 110 is uniformly provided with a plurality of air outlet holes 111 in strip structure, and the right surface of the shell 100 is provided with a circular through hole 101, and the circular through hole 101 is internally penetrated by the air inlet pipe 210, and the outer end of the air inlet pipe 210 is connected with the air outlet end of the air blower 200;

[0025] The inner end of the air inlet pipe 210 is connected with the air outlet pipe 220 inside the shell 100, and the outer surface of the air outlet pipe 220 is provided with a mounting end of the mounting pipe 230 facing the inner surface of the bottom shell 110, and the inner wall of the mounting pipe 230 is provided with threads;

[0026] The end of the mounting pipe 230 away from the air outlet pipe 220 is sealingly connected with the air outlet nozzle 240, and the air outlet end of the air outlet fan 250 installed in the air outlet pipe 220 is aligned with the inner surface of the bottom shell 110;

[0027] In use, the user first starts the air blower 200, so that the air blower 200 generates a large amount of air, and then supplies air to the air outlet pipe 220 through the air inlet pipe 210, and then supplies air to the installation pipe 230 outside the surface of the air outlet pipe 220, and then supplies air to the air outlet nozzle 240 connected with the installation pipe 230, so that air is discharged through the air outlet nozzle 240, and then the air is discharged through the air outlet hole 111 on the surface of the bottom shell 110, so that the air curtain is formed, and the reinforced fan 250 inside the air outlet pipe 220 can enhance the strength of the air curtain. Since the plurality of installation pipes 230 and the air outlet nozzles 240 connected therewith are uniformly distributed outside the air outlet pipe 220 during use, the air curtain can be uniformly sprayed to form a complete and continuous air curtain. This uniform air curtain can better control the diffusion path of the resin sand dust. Since the air outlet nozzle 240 and the installation pipe 230 are connected by a sealing thread, when a certain air outlet nozzle 240 is blocked, damaged or needs to be replaced with a different type of nozzle (such as changing the air outlet angle or air outlet strength) according to the actual production situation, the worker can conveniently detach the nozzle from the installation pipe 230 by rotating the nozzle, and then replace the new nozzle. This convenient replacement mode combined with the conveniently detachable bottom shell 110 can reduce equipment maintenance time and improve the working efficiency of the resin sand assembly line.

[0028] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
