Description

Technical Field

[0001] The embodiments of this utility model relate to the technical field of dust removal hoods for sand removal machines, specifically, to a dust removal hood for a sand removal machine. Background Technology

[0002] After casting is completed, the casting needs to enter the sand removal machine to separate the casting from the sand mold, and then the sand clumps are further crushed; however, the above process can easily cause dust to fly in the foundry workshop. Reducing dust is of great significance for eliminating the hazards of sand and dust and improving the working conditions of workers.

[0003] Current large-scale sand removal machines are usually equipped with a three-sided opening hood, with a suction fan on each side corresponding to one dust suction port. While this basically controls dust, it results in a large overall footprint, high cost, and complicated maintenance. At the same time, the position and arrangement of the dust suction ports inside the dust removal hood still need to be optimized to improve the airflow field inside the dust removal hood, so as to avoid severe gas turbulence, which would cause dust to overflow and be difficult to control. Utility Model Content

[0004] To overcome the above-mentioned defects, the present invention provides a dust hood for a sand removal machine, which solves the technical problem that the position and arrangement of the dust suction port in the dust hood still need to be optimized in the related technology in order to avoid severe gas turbulence, which would cause dust to overflow and be difficult to control.

[0005] According to one aspect, at least one embodiment of the present invention provides a dust collector hood for a sand removal machine, comprising:

[0006] The cover has two sets of dust suction ports on its two symmetrical side walls. Each set of dust suction ports includes at least one dust suction port, and the two sets of dust suction ports are staggered. The cover is used to cover the sand removal machine to prevent dust from flying.

[0007] For example, at least one embodiment of the present invention provides a dust removal hood for a sand removal machine, wherein each group of dust suction ports includes a plurality of dust suction ports arranged horizontally, and the dust suction ports are located on the top side wall of the hood.

[0008] For example, at least one embodiment of this utility model provides a dust removal hood for a sand removal machine, wherein the top walls on both sides of the hood are provided with inclined surfaces, the two inclined surfaces are symmetrically arranged, and the dust suction port is located on the inclined surface to reduce the eddy currents inside the hood.

[0009] For example, at least one embodiment of this utility model provides a dust collector hood for a sand removal machine, wherein the side wall of the hood is provided with a rope inlet / outlet, the rope inlet / outlet being located between two sets of dust suction ports, and further includes:

[0010] A closed door is slidably connected to the cover, and the closed door is configured to close or open the rope inlet / outlet after sliding.

[0011] For example, at least one embodiment of this utility model provides a dust removal hood for a sand removal machine, wherein there are two closed doors, which are symmetrically arranged, and the two closed doors slide in opposite directions and are both horizontal. After the two closed doors slide, they can close or open the rope inlet and outlet.

[0012] For example, at least one embodiment of this utility model provides a dust removal hood for a sand removal machine, wherein the top wall of the hood is provided with an opening for the sand box hoisting rope to enter.

[0013] For example, at least one embodiment of this utility model provides a dust removal hood for a sand removal machine, wherein a blocking door is rotatably provided at the edge of the opening, and the blocking door is configured to be located inside the opening after rotation, so as to reduce the amount of ash discharged at the opening.

[0014] For example, at least one embodiment of this utility model provides a dust removal hood for a sand removal machine, wherein two sets of blocking doors are symmetrically arranged at the edge of the opening, and each set of blocking doors includes at least two blocking doors arranged horizontally.

[0015] For example, at least one embodiment of this utility model provides a dust removal hood for a sand removal machine, wherein the outer wall of the hood is provided with a blower pipe, and the air outlet of the blower pipe is inclined toward the opening and / or passes horizontally through the opening to change the direction of ash discharge into the hood.

[0016] For example, at least one embodiment of this utility model provides a dust removal hood for a sand removal machine, wherein the inner wall of the hood is provided with a sound insulation layer.

[0017] The beneficial effects of the embodiments of this utility model are as follows:

[0018] In this technical solution, two sets of staggered dust extraction ports are set on the symmetrical side walls of the enclosure. From an overall layout perspective, compared to the traditional three-sided opening with both the suction fan and dust extraction ports, this solution only requires dust extraction ports on the symmetrical side walls of the enclosure, reducing the number of ports and the suction fan, and directly lowering equipment costs. Simultaneously, since it eliminates the need to arrange equipment on three separate surfaces, the equipment's footprint is reduced, resulting in more efficient space utilization and effectively solving the problem of large footprint inherent in traditional solutions.

[0019] In addition, the staggered arrangement allows the suction force generated by the dust inlet to form a more uniform and orderly airflow field within the dust hood, reducing gas turbulence and effectively preventing dust from spreading. This facilitates the control and collection of dust. During the operation of the sand removal machine, dust flies irregularly and in multiple directions. If the dust inlets are neatly arranged on the same side, the airflow near the dust inlets will be too concentrated, while the airflow in other areas will be weak, thus generating gas turbulence.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] One embodiment of this utility model provides a dust removal hood for a sand removal machine, such as... Figures 1-2 As shown, the hood 1 is the basic structure of the entire dust removal hood, which can completely cover the sand removal machine, sealing off the area where dust is generated during the operation of the sand removal machine and preventing dust from flying into the workshop in a large area. Two sets of dust suction ports 101 are provided on the symmetrical side walls of the hood 1. Each set of dust suction ports 101 includes at least one dust suction port 101. This double-sided multi-set arrangement changes the traditional mode of setting dust suction ports 101 on three sides of the opening 104. By arranging dust suction ports 101 on the side walls, the number of dust suction ports 101 can be reduced while ensuring effective coverage of the dust-generating area of ​​the sand removal machine. Taking a common medium-sized sand removal machine as an example, two sets of dust suction ports 101 can be set on each side of the left and right side walls of the hood 1. Each set contains 2 to 3 dust suction ports 101. In this way, the dust collection needs are met while reducing equipment costs and floor space.

[0035] The term "misalignment" refers to the fact that two sets of suction ports 101 on the same side wall are offset from each other by a certain distance in the vertical or horizontal direction. Specifically, one set of suction ports 101 is located near the top of the left side wall of the cover 1, and the other set is located near the top of the right side wall of the cover 1, and is offset from the set of suction ports 101 on the left side wall by a certain distance in the horizontal direction. This misalignment allows the suction force generated by the suction ports 101 when extracting dust to form a more reasonable airflow field within the dust removal cover.

[0036] When the sand removal machine generates dust, the dust suction ports 101, which are staggered on both sides of the wall, will work simultaneously, driving the air upward. The two airflows work together to avoid the formation of local turbulence in the dust removal hood, so that the dust can be sucked into the dust suction port 101 more smoothly, effectively preventing dust from overflowing and improving dust removal efficiency.

[0037] Each set of dust suction ports 101 includes several dust suction ports 101 arranged horizontally and located on the side top wall of the cover 1. It can form a horizontal coverage area on the side top wall of the cover 1 to specifically adsorb dust that spreads horizontally above the sand removal machine. Compared with random or irregular arrangement, it can capture dust more efficiently and improve dust removal efficiency. It conforms to the upward movement characteristics of dust. When the sand removal machine generates dust, the dust will be directly sucked into the dust suction ports 101 on the side top wall during the rising process, reducing the residence time and diffusion range of dust in the cover 1.

[0038] like Figures 1-2 As shown, symmetrical inclined surfaces 102 are provided on the top walls of the two sides of the cover 1, and the dust suction port 101 is placed on them. When the dust generated by the sand removal machine rises with the airflow and encounters the inclined surface 102, the airflow direction will change accordingly, avoiding airflow collision and vortex formation caused by abrupt structures such as right angles, so that the airflow can flow more smoothly to the dust suction port 101, effectively reducing the vortex inside the cover 1.

[0039] like Figures 1-3 As shown, a rope inlet / outlet 103 is provided on the side wall of the enclosure 1 and equipped with a sliding closed door 2. First, the design of the rope inlet / outlet 103 being located between two sets of dust suction ports 101 makes it convenient for operators to send the castings or materials to be processed into the sand removal machine without affecting the overall dust removal system layout. Second, the closed door 2 can effectively prevent dust from overflowing from the opening 104 when the rope inlet / outlet 103 is open, ensuring a good dust removal environment inside the enclosure 1 and ensuring that the dust suction ports 101 can continue to function efficiently and maintain a high dust removal efficiency.

[0040] Operation process: The closed door 2 and the cover 1 are connected by a sliding slider guide rail. When it is necessary to feed castings or materials into the sand removal machine, the operator manually pushes the closed door 2 so that it slides on the cover 1 along the pre-set slide rail or groove. As the closed door 2 slides, the hoisting rope inlet and outlet 103 is gradually exposed until it is fully open. At this time, the operator can put the material into the sand removal machine through the hoisting rope inlet and outlet 103 to complete the feeding operation. It can be further set up with two closed doors 2 with opposite sliding directions to quickly realize the above process.

[0041] A rotatable baffle 3 is provided at the edge of the opening 104. Direct ash discharge through the opening 104 alone may result in excessive ash discharge, and in some cases, external airflow may even backflow into the hood 1, affecting the stability of the internal airflow. The rotatable baffle 3 can adjust the flow area of ​​the opening 104 according to actual needs. When it is necessary to reduce the ash discharge, the baffle 3 is rotated to be located inside the opening 104, partially blocking the opening 104, thereby reducing the ash discharge speed and volume. When it is necessary to quickly discharge a large amount of dust, the baffle 3 is rotated to increase the area of ​​the opening 104, improving the ash discharge efficiency, achieving flexible control over the ash discharge volume, and maintaining a good airflow environment inside the hood 1.

[0042] Furthermore, two sets of blocking doors 3 are symmetrically arranged at the edge of the opening 104. Each set of blocking doors 3 includes at least two blocking doors 3 arranged horizontally, which can make the force on both sides of the opening 104 uniform and avoid uneven airflow at the opening 104 due to the action of blocking doors 3 on one side, which would affect the dust removal effect and the airflow stability inside the hood 1. Before the sand removal machine starts working, the operator adjusts the position of the blocking doors 3 in advance according to the expected sand removal workload and workshop environment. If the expected amount of dust is small, some of the blocking doors 3 in the two sets of blocking doors can be rotated to a certain angle with the opening 104, so that the opening 104 is in a slightly open state, allowing only a small amount of dust to be discharged, while maintaining a relatively stable negative pressure environment inside the hood 1, which is conducive to the efficient dust collection of the suction port 101. If it is detected that the amount of dust inside the hood 1 is gradually increasing, affecting the smooth airflow inside, the operator can rotate more blocking doors 3 through the control device or manual operation to increase the flow area of ​​the opening 104, accelerate the dust discharge speed, ensure that the amount of dust inside the hood 1 is maintained within a reasonable range, and ensure the normal operation of the dust removal system.

[0043] like Figures 5-6 As shown, during the dust removal process of the sand removal machine, the direction of dust discharged from the opening 104 may be difficult to control, easily causing dust to drift outside the hood 1 and affect the workshop environment. The air outlet of the blower duct 4 is inclined towards the opening 104 and / or passes horizontally through the opening 104. By blowing air, it applies force to the dust discharged from the opening 104, which can guide the originally disordered dust discharge direction to a designated area inside the hood 1, preventing dust from overflowing and effectively improving the air quality in the workshop.

[0044] Specifically, a blower pipe 4 can be installed on the outer wall of the enclosure 1, with its air outlet tilted towards the opening 104. This form is suitable for scenarios where the dust discharge direction is relatively simple and the dust needs to be concentrated and guided to a specific area inside the enclosure 1. Alternatively, two blower pipes 4 can be symmetrically installed on the outer wall of the enclosure 1 on both sides of the opening 104, with the air outlets passing through the opening 104 in a horizontal direction. This form can apply a lateral airflow force to the discharged dust from both sides, so that the dust is confined in the horizontal direction inside the enclosure 1.

[0045] Additionally, a sound insulation layer can be installed on the inner wall of the enclosure 1 to further improve the sound insulation effect.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
