Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mufflers, and particularly relates to a muffler for an exhaust system of a core shooter. Background Art
[0002] During the process of producing sand cores by a core shooter, it is necessary to inject sand into the internal mold. Therefore, gas with a certain pressure will be generated. After the core shooter produces sand cores, the gas needs to be discharged. The discharged gas carries sand. In order to slow down the flow rate of the gas discharged from the core shooter, a plug with dense small holes is installed at the air outlet of the equipment, and the air is discharged dispersedly through the small holes to achieve a noise reduction effect.
[0003] However, the discharged air will be mixed with sand grains, and the sand grains are likely to block the exhaust small holes, making it difficult for the gas of the core shooter to be discharged, resulting in poor exhaust effect of the equipment. Moreover, the exhaust plug also needs to be replaced frequently. Summary of the Utility Model
[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a muffler for an exhaust system of a core shooter, which can reduce noise and solve the problem of blockage caused by sand grains in the air.
[0005] A muffler for an exhaust system of a core shooter according to an embodiment of the first aspect of the utility model includes a tank body, and a first buffer assembly and a second buffer assembly located inside the tank body. The tank body has an air inlet and an air outlet, and the air inlet and the air outlet are respectively located at both ends of the tank body. The first buffer assembly and the second buffer assembly are arranged vertically in sequence, and the first buffer assembly and the second buffer assembly are arranged in sequence from the air inlet to the air outlet direction. A gas guiding channel connecting the air inlet and the air outlet is formed between the first buffer assembly and the second buffer assembly; the first buffer assembly includes a plurality of first baffles for slowing down the air flow rate, and the plurality of first baffles are arranged side by side from the air inlet to the air outlet direction, and a first buffer cavity is formed between two adjacent first baffles; the second buffer assembly includes a plurality of second baffles for slowing down the air flow rate, and the plurality of second baffles are arranged side by side from the air outlet to the air inlet direction, and a second buffer cavity is formed between two adjacent second baffles, and the top of the second baffle is higher than the bottom of the first baffle.
[0006] A muffler for an exhaust system of a core shooter according to an embodiment of the utility model has at least the following beneficial effects:
[0007] 1. The utility model sets a number of first baffles. When the sand core machine releases pressure, the discharged gas and air enter the interior of the tank through the air inlet. The first baffle can block the gas, causing the gas to flow along the bottom of the first baffle. Moreover, the gas can enter the first buffer chamber formed between the first baffles, which is beneficial to gradually slow down the flow rate of the gas. At the same time, the first baffle can make the sand grains entrained by the gas fall onto the inner wall of the tank, avoiding the use of a plug with a dense small hole for sound absorption and solving the problem of blockage of the small holes in the plug.

When the gas passes through the air guide channel, the second baffle can further block the gas, further slowing down the flow rate of the gas. And the top of the second baffle is higher than the bottom of the first baffle. The second baffle prevents the sand grains from flowing out of the air guide channel. The slowed-down gas is discharged through the air outlet, weakening the noise generated by the gas discharge and optimizing the exhaust effect of the sand core machine.
[0009] According to some embodiments of the utility model, the air guide channel has a sand separation section extending vertically. The sand separation section is formed between the first baffle and the second baffle. The tank is provided with a sand discharge port, and the sand discharge port is located at the bottom end of the sand separation section.
[0010] According to some embodiments of the utility model, a ball valve is provided at the sand discharge port, and the ball valve is used to open or close the sand discharge port.
[0011] According to some embodiments of the utility model, the air guide channel has an air inlet section. The tank has a first side wall provided with the air inlet. The air inlet section is formed between the first side wall and the first baffle.
[0012] According to some embodiments of the utility model, the air guide channel has a first buffer section, and the first buffer section is communicated with the first buffer chamber.

[0026] The following describes a muffler of an exhaust system of a core-making machine according to an embodiment of the present utility model with reference to the accompanying drawings.
[0027] Refer to Figure 1 , a muffler of an exhaust system of a core-making machine according to an embodiment of the present utility model includes a tank body 100, and a first buffer assembly and a second buffer assembly located inside the tank body 100. The tank body 100 has an air inlet 110 and an air outlet 120. The air inlet 110 and the air outlet 120 are respectively located at both ends of the tank body 100. The first buffer assembly and the second buffer assembly are sequentially arranged up and down, and the first buffer assembly and the second buffer assembly are sequentially arranged from the air inlet 110 to the air outlet 120. A gas guiding channel 130 communicating the air inlet 110 and the air outlet 120 is formed between the first buffer assembly and the second buffer assembly.
[0028] Among them, the first buffer assembly includes a plurality of first baffles 140 for slowing down the air flow speed. The plurality of first baffles 140 are arranged side by side from the air inlet 110 to the air outlet 120, and a first buffer chamber 150 is formed between two adjacent first baffles 140.
[0029] In some embodiments of the present utility model, the gas guiding channel 130 has an air inlet section 200. The tank body 100 has a first side wall provided with the air inlet 110, and the air inlet section 200 is formed between the first side wall and the first baffle 140.
[0030] It can be understood that there is a certain space between the first side wall and the first baffle 140. The first baffle 140 can directly block the gas at the air inlet 110, or part of the gas can directly flow through the bottom of the first baffle 140, thereby helping to slow down the gas flow speed.
[0031] In some embodiments of the present utility model, the air guiding channel 130 has a first buffer section 210, and the first buffer section 210 communicates with the first buffer chamber 150.
[0032] Thus, when the gas passes through the first buffer section 210, it can enter each first buffer chamber 150, gradually slowing down the flow rate of the gas, and can also greatly reduce the noise effect.
[0033] Wherein, the second buffer assembly includes a plurality of second baffles 160 for slowing down the air flow rate. The plurality of second baffles 160 are arranged side by side in the direction from the air outlet 120 to the air inlet 110. A second buffer chamber 170 is formed between two adjacent second baffles 160, and the top of the second baffle 160 is higher than the bottom of the first baffle 140.
[0034] In some embodiments of the present utility model, the air guiding channel 130 has a sand separation section 180 extending vertically. A sand separation section 180 is formed between the first baffle 140 and the second baffle 160. The tank body 100 is provided with a sand discharge port, and the sand discharge port is located at the bottom end of the sand separation section 180.
[0035] Thus, when the gas passes through the sand separation section 180, the second baffle 160 can block the sand grains entrained by the gas, separating the sand grains from the gas. The sand grains fall into the sand discharge port, preventing the sand grains from being discharged outside following the gas.
[0036] In some embodiments of the present utility model, a ball valve 190 is provided at the sand discharge port, and the ball valve 190 is used to open or close the sand discharge port.
[0037] According to the actual production situation, at regular intervals for discharging sand grains, when discharging sand, the ball valve 190 can be opened to allow the sand grains to be discharged from the sand discharge port. After the discharge is completed, the ball valve 190 is closed.
[0038] In some embodiments of the present utility model, the air guiding channel 130 has a second buffer section 220, and the second buffer section 220 communicates with the second buffer chamber 170.
[0039] Thus, when the gas passes through the second buffer section 220, it can enter each second buffer chamber 170, gradually slowing down the flow rate of the gas, and can also greatly reduce the noise effect.
[0040] In some embodiments of the present utility model, the air guiding channel 130 has an exhaust section 230. The tank body 100 has a second side wall provided with an air outlet. An exhaust section 230 is formed between the second side wall and the second baffle 160. Thus, the gas with reduced speed is discharged from the air outlet to the inside of the tank body 100.
[0041] In some embodiments of the present utility model, both the first baffle 140 and the second baffle 160 are made of steel plates. Therefore, the manufacturing costs of the first baffle 140 and the second baffle 160 are low, and they can be fixed inside the tank body 100 by welding.
[0042] In a further embodiment of the present utility model, referring to Figure 2 , the tank body 100 is a cylindrical tank, and both the first baffle 140 and the second baffle 160 are semi-circular steel plates matching the inner wall of the cylindrical tank. Therefore, the structures of the first baffle 140 and the second baffle 160 are simple and the manufacturing costs are low.
[0043] In the description of this specification, the descriptions with reference to terms such as "one embodiment, some embodiments, illustrative embodiments, examples, specific examples or some examples" etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
[0044] The embodiments of the present utility model have been described in detail above with reference to the drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art to which it pertains.
