Description

Technical Field

[0001] This invention belongs to the field of silencer technology and relates to a water-cooled silencer. Background Technology

[0002] Exhaust processes are involved in various technical fields such as medical, chemical, industrial, and mechanical equipment. These processes often involve significant noise, causing substantial noise pollution to the surrounding area. To address this, a water-cooled muffler has emerged on the market, such as the one described in Chinese Patent No. "202220266508.6". The specific structure of this water-cooled muffler includes a muffler housing, within which a dry muffler housing is installed. A circulating water jacket is formed between the dry muffler housing and the muffler housing. An inlet is located on the back of the muffler housing, and an outlet is located on the side. The inlet and outlet are connected to the circulating water jacket. An engine exhaust port is located on the bottom of the muffler housing, and a muffler outlet is located on the back. The engine exhaust port and the muffler outlet are connected to the interior of the dry muffler housing. A muffler water temperature sensor is located on the bottom of the muffler housing. The engine exhaust port is connected to the exhaust port of the engine to be silenced. The high-temperature exhaust gas emitted by the engine enters the dry muffler housing for noise reduction and then exits from the muffler outlet. Flowing cooling water enters the circulating water jacket through the inlet. The water in the circulating water jacket surrounds the dry muffler housing, absorbing some of the noise and vibration transmitted from the housing, further reducing the overall noise. Simultaneously, the flowing cooling water cools the dry muffler housing. In this structure, the contact area between the cooling water and the muffler housing is small, resulting in poor muffler cooling and limited reduction of exhaust noise by the cooling water, leading to unsatisfactory noise reduction. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing a water-cooled muffler with good cooling performance.

[0004] The objective of this invention can be achieved through the following technical solution: A water-cooled muffler includes a housing and a core. The housing is sleeved and installed on the core. A cooling water channel is formed in the side wall of the housing. A cooling water inlet and a cooling water outlet are formed on the housing and communicate with the cooling water channel. A core water partition is provided inside the core. The core water partition is connected to a cooling water inlet and a cooling water outlet.

[0005] In the above-mentioned water-cooled silencer, the core is provided with several baffles, including an annular end baffle, several first baffles and several second baffles. The lower part of the end baffle has several through holes, the bottom of the first baffle has several through holes, and the top of the second baffle has several through holes.

[0006] In the aforementioned water-cooled silencer, the housing is provided with an air inlet, an air outlet, and a drain outlet.

The cavity on the right side of the air inlet cavity is an annular deflector ventilation cavity. The drain outlet communicates with the annular deflector ventilation cavity. Several first baffles and second baffles are alternately arranged in the annular deflector ventilation cavity. The annular deflector ventilation cavity communicates with the buffer cavity through a through hole at the bottom of the end baffle and a through hole at the bottom of the first baffle. The inner annular cavity is a straight-through annular airflow channel.

[0007] In the water-cooled silencer described above, the distance between several of the baffles gradually increases.

[0008] In the aforementioned water-cooled silencer, the lower part of the end baffle has seven through holes, the bottom of the first baffle has three through holes, and the top of the second baffle has three through holes.

[0009] In the above-mentioned water-cooled muffler, the core is also provided with reinforcing ribs. The reinforcing ribs connect the end baffle, the first baffle and the outer wall of the core. The reinforcing ribs make the air intake chamber fan-shaped.

[0010] In the aforementioned water-cooled muffler, a thin-walled corrugated pipe is provided inside the air inlet, which communicates with the air inlet chamber, and the outer wall of the thin-walled corrugated pipe is connected to the cooling water flow channel.

[0011] In the above-mentioned water-cooled silencer, a hollow air outlet pipe is provided inside the housing. The air outlet pipe is installed on the air outlet. The end of the air outlet pipe extends into the core and communicates with the inner annular cavity. The end of the air outlet pipe is provided with a plurality of vent holes, which are arranged circumferentially along the pipe wall of the air outlet pipe.

[0012] In the above-mentioned water-cooled muffler, the airflow enters the intake chamber through the thin-walled corrugated pipe, and after being deflected by the reinforcing ribs, the airflow enters the buffer chamber, then passes through the end baffle, several alternating first baffles and second baffles in sequence, and then enters the inner annular cavity. It then enters the outlet pipe through the vent hole and is discharged through the outlet pipe.

[0013] In the aforementioned water-cooled silencer, the core includes an inner sleeve and an outer sleeve, forming a core water-cooling barrier between the inner sleeve and the outer sleeve. The core water-cooling barrier contains two baffles located at the midpoint between the two sides of the barrier, dividing it into an upper cavity and a lower cavity. The ends of the two baffles are provided with upper water inlets connecting the upper and lower cavities of the core water-cooling barrier. The upper water inlets and the cooling water inlet are located at opposite ends of the core. Cooling water enters the lower cavity of the core water-cooling barrier from the cooling water inlet, then enters the upper cavity through the upper water inlet, and finally flows to the cooling water outlet.

[0014] In the above-mentioned water-cooled silencer, the end of the core is provided with a core flange, and both ends of the core flange are provided with positioning steps. The end of the housing is provided with a housing flange, and the housing flange is provided with positioning holes. The core flange and the housing flange are fixedly connected by screws, and the positioning holes and the positioning steps cooperate with each other.

[0015] In the above-mentioned water-cooled silencer, the cooling water inlet and the cooling water outlet are located on the core flange, and both the cooling water inlet and the cooling water outlet are equipped with quick-release flange joints.

[0016] In the aforementioned water-cooled silencer, a triangular rib is provided between the core flange and the outer sleeve.

[0017] In the aforementioned water-cooled silencer, a watertight plate is provided inside the inner sleeve.

[0018] In the above-mentioned water-cooled muffler, the top of the housing is provided with an air inlet flange, the cooling water flow channel extends into the interior of the air inlet flange, the cooling water flow channel covers the outside of the housing, the cooling water inlet is located at the bottom of the housing, the cooling water outlet is located on the air inlet flange at the top of the housing, and the cooling water inlet and the cooling water outlet are respectively located at both ends of the housing.

[0019] Compared with existing technologies, this water-cooled muffler features dual cooling of the outer shell and the core. The baffle plate increases the contact area between the gas and the core, thereby increasing the cooling area and resulting in better cooling performance. By designing the inlet pipe as a corrugated pipe structure, the cooling area is increased, improving cooling efficiency. The use of thin-walled corrugated pipes, combined with the reinforcing effect of the corrugated pipe structure and the buffering effect of the cooling water channels in the shell, further enhances heat transfer efficiency and improves cooling efficiency. This water-cooled muffler achieves its noise reduction effect by weakening the noise source energy, improving the sound insulation effect of the shell, and extending the airflow distance for sound propagation. The cooling water channels on the shell reduce the temperature of the muffler's external contact surfaces to a safe range for human contact, preventing burns from accidental contact. The muffler adopts a detachable core structure, and the core's flow passage section uses a fully open design, making cleaning convenient and effective. Exhaust is unobstructed, with low exhaust pressure and minimal power loss. The annular airflow separates the gas and liquid, allowing the liquid to flow straight and quickly through the gap between the core and the shell, preventing liquid accumulation and blockage of the annular exhaust channels.

Detailed Implementation

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figure 1-4 As shown, this water-cooled silencer includes a housing 1 and a core 2. The core 2 includes an inner sleeve 21 and an outer sleeve 22. The core 2 is a hollow cylinder, and a core water separator is formed between the inner sleeve 21 and the outer sleeve 22.

[0027] In the above technical solution: the end of the core 2 is provided with a core flange 23, on which a cooling water inlet 24 and a cooling water outlet 25 are provided, both of which are connected to the core water partition. Both the cooling water inlet 24 and the cooling water outlet 25 are equipped with quick-release flange joints 211, which facilitate the connection and disconnection of the core 2 with external cooling water equipment. A triangular rib 26 is provided between the core flange 23 and the outer sleeve 22, which strengthens the structure of the outer sleeve 22, eliminates the weakness of the cantilever beam structure of the outer sleeve 22, and prevents forced vibration of the core 2.

[0028] In the above technical solution: Two baffles 27 are provided inside the core water partition. The baffles 27 are located in the middle of both sides of the core water partition, dividing it into upper and lower chambers. At the ends of the two baffles 27, there are upper water inlets 28 connecting the upper and lower chambers of the core water partition. The upper water inlets 28, along with the cooling water inlet 24 and cooling water outlet 25, are located at both ends of the core 2. Cooling water enters the lower chamber of the core water partition from the cooling water inlet 24 and flows to the other end. Then, it enters the upper chamber of the core water partition through the upper water inlet 28 and flows to the cooling water outlet 25, preventing stagnant water in certain areas of the core water partition. The baffles 27 are welded to the outside of the inner sleeve 21 and tightly connected to the outer sleeve 22, improving the positioning accuracy between the inner sleeve 21 and the outer sleeve 22, making the surrounding water flow channels relatively uniform, thus ensuring relatively uniform cooling water flow rate and temperature, and improving the cooling effect of the core 2.

[0029] In the above technical solution: a watertight plate 29 is provided inside the inner sleeve 21. The watertight plate 29 and the left end of the inner sleeve 21 form a closed space, which can prevent water leakage inside the inner sleeve 21 caused by weld defects.

[0030] In the above technical solution: the core 2 is provided with several baffles. These baffles include end baffles 3, several first baffles 4, and several second baffles 5. The lower part of the end baffles 3 has seven through holes. The bottom of the first baffles 4 has three through holes, and the top of the second baffles 5 has three through holes. The first baffles 4 and second baffles 5 are alternately arranged. The distance between some of the baffles gradually increases.

[0031] In the above technical solution: the shell 1 is fitted onto the core 2, and the end of the shell is provided with a shell flange. The shell flange and the core flange 23 are fixedly connected by screws. The shell 1 can be removed from the core 2 by loosening the screws. The shell flange has positioning holes, and the core flange 23 has positioning steps 212. The positioning holes and positioning steps 212 of the shell flange cooperate to position the installation between the shell 1 and the core 2, so that the core 2 is fixed in the center of the shell 1, and the peripheral gap is uniform, which facilitates liquid flow.

[0032] In the above technical solution: the shell 1 has an air inlet, an air outlet 12, and a liquid outlet 13. The internal cavity of the shell 1 is divided into an outer annular cavity and an inner annular cavity that are interconnected by the core 2. The outer annular cavity is divided into several annular cavity segments by several baffles on the core. The cavity directly below the air inlet is the air inlet cavity, the left side wall of which is an end baffle 3, and the right side wall of which is a first baffle 4. The annular cavity on the left side of the air inlet cavity is a buffer cavity, which is connected to the air inlet cavity through a through hole on the end baffle 3. The cavity on the right side of the air inlet cavity is an annular deflection ventilation cavity, which is connected to the annular deflection ventilation cavity by the liquid outlet 13. Several first baffles 4 and second baffles 5 are alternately arranged in the annular deflection ventilation cavity, which is connected to the buffer cavity through the bottom through hole of the end baffle 3 and the bottom through hole of the first baffle 4. The inner annular cavity is a straight-through annular airflow channel. The drain port 13 is used to drain the liquid in the inner cavity of the shell 1. The drain port 13 is located at the tail end of the shell 1 because the tail end of the shell 1 is the first place to accumulate liquid under the action of airflow.

[0033] In the above technical solution: a cooling water channel 15 is formed inside the side wall of the housing 1, and an air inlet flange is provided at the top of the housing 1. The cooling water channel 15 extends into the interior of the air inlet flange, and the cooling water channel completely covers the outer side of the housing 1. A cooling water inlet 16 communicating with the cooling water channel 15 is formed at the bottom of the housing 1, and a cooling water outlet 17 communicating with the cooling water channel 15 is formed on the air inlet flange at the top of the housing 1. The cooling water inlet 16 and the cooling water outlet 17 are located at opposite ends of the housing 1.

[0034] In the above technical solution: a thin-walled corrugated pipe 11 is provided inside the air inlet, which communicates with the air intake chamber. The outer wall of the thin-walled corrugated pipe 11 is connected to the cooling water channel 15. The thin-walled corrugated pipe 11, as an air intake pipe, can increase the cooling area and improve the cooling efficiency. The corrugated structure enhances the compressive strength of the thin-walled pipe, which can reduce the pipe wall thickness, improve the heat transfer efficiency of the air intake pipe, and further improve the cooling efficiency. The cooling water channel 15 is filled with cooling water, which squeezes the thin-walled corrugated pipe 11 inward, thereby improving the ability of the thin-walled corrugated pipe 11 to resist the impact of internal airflow and avoiding forced vibration of the thin-walled corrugated pipe 11.

[0035] In the above technical solution: the housing 1 is provided with a hollow vent pipe 14, the vent pipe 14 is installed on the vent port 12, the end of the vent pipe 14 extends into the inner sleeve 21 and communicates with the inner annular cavity, and the end of the vent pipe 14 is provided with a number of vent holes 141, the vent holes 141 are arranged in multiple rows and are arranged circumferentially along the pipe wall of the vent pipe 14.

[0036] In the above technical solution: the air intake chamber is provided with three reinforcing ribs 210. The reinforcing ribs 210 connect the end baffle 3, the first baffle 4, and the outer wall of the core 2. The three reinforcing ribs 210 are distributed in a triangular pattern, making the air intake chamber fan-shaped. The two reinforcing ribs on the lower sides isolate the air intake chamber from the lower air passage. The reinforcing ribs 210 enhance the structural strength of the end baffle 3 and the first baffle 4, preventing forced vibration and noise generation of the baffles, while increasing the cooling area of ​​the air intake chamber and improving the cooling effect.

[0037] The core cooling water enters the core water compartment through the cooling water inlet 24 and flows to the cooling water outlet 25 through the upper water outlet 28. The shell cooling water also enters the cooling water channel 15 inside the shell 1 through the cooling water inlet 16 and exits through the cooling water outlet 17. The cooling water outlet 17 is located at the top of the cooling water channel 15 to avoid local stagnant water at the top of the cooling water channel 15, thus preventing local overheating due to the inability to exchange water in certain parts of the cooling water channel 15. It also prevents air from being trapped at the top of the cooling water channel 15, thus preventing local blasting and allowing nearby cooling water to oscillate, which would significantly reduce the noise reduction effect of the cooling water channel 15. At the same time, local blasting would severely weaken the strengthening effect of the surrounding cooling water on the bellows structure, making the bellows susceptible to forced vibration and damage.

[0038] The airflow enters the fan-shaped intake chamber through the thin-walled corrugated pipe 11. The airflow is then deflected by the two reinforcing ribs 210 on both sides of the lower part, and enters the buffer chamber through the vent in the middle of the end baffle 3. The buffer chamber smooths the fluctuations in the exhaust airflow and promotes the sedimentation of liquid and solid substances within the airflow, preventing backflow of liquid and solids. Next, the airflow sequentially enters the annular deflection ventilation chamber through the bottom vents of the end baffle 3 and the first baffle 4. Several first baffles 4 and second baffles 5 are alternately arranged within the annular deflection ventilation chamber to alternately guide the airflow in an upward or downward annular flow. Then, the airflow enters the annular channel within the inner sleeve 21 and flows straight forward. The gas enters the outlet pipe 14 through the vent 141 and the end hole of the outlet pipe 14, and is then discharged through the outlet pipe 14. The alternating guidance of the vents on the first baffle plate 4 and the second baffle plate 5 transforms the exhaust airflow into a ring-shaped reversible flow, significantly extending the gas flow distance and reducing the airflow's ability to transmit noise, thereby achieving noise reduction. Furthermore, the ring-shaped exhaust airflow facilitates gas-liquid separation using centrifugal force. The uniform gap between the outer edge of the baffle plate of the core 2 and the inner cavity of the shell 1 allows for rapid liquid flow after gas-liquid separation, preventing liquid accumulation inside the shell 1 from clogging the ring-shaped exhaust channel. The baffle plate is fixed to the outer surface of the outer sleeve 22, increasing the contact area between the gas and the core 2, thus increasing the cooling area and improving the cooling effect. The exhaust pipe 14 extends into the inner sleeve 21, increasing the effective cooling area and improving the cooling effect. The vents 141 on the exhaust pipe 14 are arranged in multiple rows circumferentially. When the airflow passes through, the gas in the airflow can enter the exhaust pipe 14 through the vents 141. The liquid and solid are relatively less likely to change their direction of movement, maintaining a straight line motion and depositing on the inner wall of the inner sleeve, effectively reducing the amount of liquid and solid entering the exhaust pipe.

[0039] All vent holes on the baffles in this water-cooled silencer are round holes, and the baffles have high strength, which can prevent the baffles from being forced to vibrate.

[0040] This water-cooled silencer features dual cooling of the outer shell and the core. The baffle plate increases the contact area between the gas and the core 2, thereby increasing the cooling area and achieving good cooling effect. By setting the air inlet pipe as a corrugated pipe structure, the cooling area is increased and the cooling efficiency is improved. Furthermore, the use of thin-walled corrugated pipes, which utilize the reinforcing effect of the corrugated pipe structure and the buffering effect of the cooling water flow channel in the shell, results in high heat transfer efficiency and further improves the cooling efficiency.

[0041] This water-cooled silencer achieves its noise reduction effect by weakening the noise source energy, improving the sound insulation effect of the casing 1, and extending the airflow distance for sound propagation. The cooling effect rapidly and significantly reduces the airflow temperature, and through the principle of thermal expansion and contraction, the gas volume flow rate decreases substantially, thereby reducing the impact intensity of the airflow. The noise source energy decreases, and the noise intensity generated by the airflow in the silencer is weak, with minimal impact. Simultaneously, the cooling water channel 15 acts as a buffer layer, reducing the vibration of the casing 1, thus significantly reducing the ability of the casing 1 to propagate sound. Furthermore, the cooling water channel 15 extends into the air inlet flange, achieving full coverage of the outer surface of the air inlet end of the casing 1. At the same time, the outlet is positioned at the highest point to ensure no bulging within the cooling water channel. The airflow phenomenon effectively improves the sound insulation effect of the shell 1; by alternately setting the first and second baffles to create multiple deflection effects, the airflow travels a longer distance within the shell 1, reducing the effect of noise propagation through the airflow; by alternately setting the first and second baffles, the airflow direction is continuously and significantly changed, gradually weakening the propagation of airflow disturbance caused by periodic backflow and exhaust, making the airflow gradually flow smoothly, and limiting the airflow velocity at the outlet to avoid generating new noise sources; the front baffles have a small interval and a large number of deflections, weakening airflow fluctuations quickly and making the airflow tend to stabilize more quickly, while the rear baffles have a large interval and a large channel area, resulting in a slow airflow velocity and low impact force, which can avoid secondary airflow noise near the outlet.

[0042] This water-cooled muffler effectively reduces airflow temperature, decreasing the corrosiveness of corrosive substances and extending the muffler's service life. Cooling water channels 15 on the shell 1 lower the temperature of accessible surfaces to a safe range for human contact, preventing burns from accidental contact. All flow surfaces of the core 2 are free of localized depressions, preventing liquid accumulation and reducing the risk of corrosion damage to weak points such as welds. The muffler features a detachable core structure with a fully open design for easy and effective cleaning. Exhaust is unobstructed with low pressure and minimal power loss. The circular airflow separates the gas and liquid, allowing the liquid to flow quickly and linearly through the gap between the core 2 and the shell 1, preventing liquid accumulation and blockage of the circular exhaust channels.
