Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of dust collector, and relates to a wet dust collector, in particular to a self-excited wet dust collector. BACKGROUND

[0002] When polishing and grinding the outer surface of a workpiece, dust will be generated. The dust floating in the air will pollute the environment and seriously endanger the health of the workers. Moreover, some dust can even cause explosion. Therefore, it is necessary to use a dust collector to treat the dust. The dust collector is divided into a dry dust collector and a wet dust collector. The wet dust collector is more widely used. The wet dust removal is a method for purifying gas by fully contacting water with dust-containing gas and washing dust down. It is particularly suitable for treating high-temperature, high-humidity, flammable and explosive dust-containing gas. The traditional wet dust collector uses a water pump to supply water for spraying (i.e. the water is pumped into the wet dust collector through a pipeline by the water pump to spray and remove dust). However, the washing liquid will become dirtier and dirtier as the dust removal time increases. This will cause the water pump to be blocked and shorten its service life.

[0003] Therefore, a wet polishing dust collector is disclosed in Chinese Patent Application No. 201720075881.2. The wet polishing dust collector includes a shell having an inner cavity. The bottom of the inner cavity of the shell is a water storage area. The front part of the inner cavity is a polishing dust collection area. The side wall of the polishing dust collection area is provided with an operating port. The rear part of the inner cavity is an air outlet area. The polishing dust collection area and the air outlet area are separated by a partition plate fixedly connected to the shell. The side wall of the air outlet area of the shell is provided with an air outlet. The shell is also provided with a liquid level control mechanism for controlling the water level in the water storage area to leave a wind gap between the bottom edge of the partition plate and the liquid surface. A water vapor separation structure is arranged in the air outlet area or connected in series with the air outlet. The water vapor separation structure is a plurality of inclined plates arranged in the air outlet area and fixedly connected to the shell. In use, a certain amount of water is stored in the water storage area to ensure that a wind gap is left between the liquid surface of the water and the bottom edge of the partition plate. The dust generated during polishing is located in the polishing dust collection area. When the fan is started, the airflow will suck the dust into the air outlet area through the wind gap. The airflow speed is high when the airflow passes through the wind gap, which will force a large amount of water to splash on the liquid surface. The water mist formed by the water splash will mix with the airflow. As a result, water vapor will be mixed in the airflow. After the airflow containing water vapor and dust is separated by the separation mechanism (the water vapor separation structure is composed of a plurality of inclined plates. The inclined plates make the airflow flow in a winding and tortuous manner. The water mist will lose kinetic energy and condense on the surface of the inclined plate after colliding with the inclined plate), clean air will flow out of the air outlet, and dust and water vapor will adhere to the inclined plate. When the water vapor accumulates into a water flow, it will carry the dust down the inclined plate and return. The wet polishing dust collector uses the attraction of the fan to make the water self-excitation at the wind gap. It does not need to rely on the water pump to spray water mist, thereby eliminating the water pump blockage phenomenon.

[0004] However, according to the requirements of 8-4-10 in the national standard GB15577-2018 Dust Explosion Prevention Safety Regulations and the requirements of 5-2-2 in the national safety production line rule AQ4273-2016, in order to ensure the dust removal effect and use safety, the water quantity and water pressure of the wet dust collector should be provided with monitoring and alarm devices. In the conventional water pump water supply spray wet dust collector, the water quantity monitoring is realized by setting a liquid level sensor in the water storage area, and the water pressure monitoring is realized by setting a pressure sensor on the water pump water supply pipe. Compared with the water pump water supply spray wet dust collector, the water quantity monitoring of the self-excited dust collector can use the same structure, but the water pressure cannot be monitored and alarmed because it uses the water spray generated by the airflow on the water surface, so there is a safety problem. SUMMARY

[0005] The purpose of the present application is to solve the problem of safety caused by the inability to monitor the water pressure in the prior art.

[0006] The purpose of the present application can be achieved by the following technical solutions:

[0007] The self-excited wet dust collector comprises a fan and a shell with a dust removal cavity and a dust collection cavity, the bottom of the dust removal cavity is communicated with the bottom of the dust collection cavity, and a water vapor separation piece is arranged in the dust removal cavity, characterized in that a water collecting piece is fixed in the dust removal cavity, the water collecting piece has a substantially tubular body and a water inlet portion connected to the upper end of the body, the flow cross-sectional area of the water collecting piece at the water inlet portion is greater than the flow cross-sectional area of the water collecting piece at the connection between the water inlet portion and the body, the self-excited wet dust collector further comprises a sensor capable of detecting the water pressure in the body and an alarm capable of alarming when the value detected by the sensor is less than a set value.

[0008] The self-excited wet dust collector is the same as the existing self-excited wet dust collector in dust removal, and water is filled in the shell, the water is located at the bottom of the dust removal chamber and the dust collection chamber, and the liquid level of the water is lower than the upper edge of the communication part of the dust collection chamber and the dust removal chamber. When the fan starts, the airflow is sucked into the dust collection chamber from the outside and enters the dust removal chamber together with the dust in the dust collection chamber. At the same time, the airflow will force the water surface to produce a large amount of water splashes. The water splashes will fall downward under the action of gravity after reaching a certain height. The self-excited wet dust collector is provided with a water collecting part in the dust removal chamber. The water collecting part has a substantially tubular body and a water inlet portion connected to the upper end of the body. The cross-sectional area of the flow passage of the water inlet portion is greater than that of the connection part between the water inlet portion and the body. In this way, during the dust removal process, the water splashes falling under the action of gravity can be continuously collected by the water inlet portion, and the continuously collected water splashes can enter the tubular body to form a continuous flow state. The water flow will always generate water pressure (just like the state of continuously pumping water into the pipe by the water pump). In this way, the sensor can detect the water pressure, and an alarm can be given when the detected water pressure value is lower than the set value. Through the above arrangement, the self-excited wet dust collector can monitor the water pressure during work and give an alarm, thereby improving the safety of use.

[0009] In the self-excited wet dust collector described above, the body side is connected with a connecting pipe extending out of the shell, and the sensor is connected to the end of the connecting pipe outside the shell. The cross-sectional area of the flow passage of the water collecting part at the upper end of the body is greater than that of the water collecting part at the lower end of the body.

[0010] By connecting the connecting pipe extending out of the shell to the side of the body, the sensor can be arranged outside the shell while detecting the water pressure of the flowing water in the body. In this way, the alarm can be given when the pressure detected by the sensor is lower than the set value, and at the same time, the pressure display can be realized by arranging the sensor outside the shell, so as to facilitate the staff to master the internal working condition.

[0011] At the same time, the cross-sectional area of the flow passage of the water collecting part at the upper end of the body is set to be greater than that of the water collecting part at the lower end of the body. In this way, on the basis of ensuring that the upper end of the body can normally enter and the lower end can normally exit (i.e. ensuring that the water in the body is in a flowing state), the water collected from the water inlet portion and flowing into the body can also smoothly flow into the connecting pipe to ensure that the sensor can accurately read the pressure of the flowing water in the body.

[0012] In the self-excited wet dust collector described above, a plug is connected in the lower end of the body, and a drain hole is arranged on the plug.

[0013] In practice, the water flowing into the tubular body is discharged from the drain hole to form a flow. The plug is connected to the lower end of the body, and the drain hole is provided on the plug. The cross-sectional area of the flow passage of the water collecting member at the upper end of the body is greater than that at the lower end of the body, so that a continuous water flow is formed in the body during the dust removal process, and the water pressure can be detected at all times to ensure reliability.

[0014] In the self-excited wet dust collector described above, a valve is connected to the lower end of the body as another technical solution.

[0015] The cross-sectional area of the flow passage of the water collecting member at the upper end of the body is greater than that at the lower end of the body by adjusting the opening of the valve, so that a continuous water flow is formed in the body during the dust removal process, and the water pressure can be detected at all times to ensure reliability.

[0016] In the self-excited wet dust collector described above, the connecting pipe includes a pipe body one and a pipe body two. The housing has a mounting hole, one end of the pipe body one extends out of the mounting hole and is threadedly connected to one end of the pipe body two, the sensor is connected to the other end of the pipe body two, and the outer side of the pipe body one has a shoulder. The housing where the mounting hole is located is clamped between the shoulder on the outer side of the pipe body one and the end of the pipe body two.

[0017] During installation, one end of the pipe body one is threaded through the mounting hole and out of the housing, and the pipe body two is threadedly connected. In this way, the housing where the mounting hole is located is clamped and fixed between the shoulder on the outer side of the pipe body one and the end of the pipe body two, thereby achieving the installation and fixation of the water collecting member in the housing. This installation method is convenient, and the water collecting member, the connecting pipe and the sensor form a modular structure and can be used on any self-excited wet dust collector.

[0018] In the self-excited wet dust collector described above, the cross-sectional area of the flow passage of the water inlet portion gradually decreases from top to bottom.

[0019] Through the above arrangement, it means that the inner wall of the water inlet portion is generally inclined, which can play a role in quickly collecting water into the body, so that the sensor can detect the water pressure in time.

[0020] In the self-excited wet dust collector described above, the water inlet portion is in the shape of a horn.

[0021] The shape of the horn is more conducive to the collection of water splashes, so that the sensor can quickly and reliably detect the water pressure and the alarm can timely alarm when the water pressure detected by the sensor is lower than the set value, further improving the safety of use.

[0022] The water collecting member is located in the lower part of the dust removal chamber.

[0023] The water splashes generated by the airflow on the water surface in the lower part of the dust removal chamber are the most, and the water collecting member is arranged in the lower part of the dust removal chamber, which is more conducive to forming a continuous flow state in the tubular body, so that the sensor can detect the water pressure in time and alarm when the water pressure is lower than the set value, thereby improving the safety of the self-excited wet dust collector in use.

[0024] In the self-excited wet dust collector, a connecting plate is fixed in the dust removal chamber, and the connecting plate cooperates with the front inner wall and the left and right inner walls of the dust removal chamber to form a water storage tank below the water vapor separation member. The connecting plate and the rear inner wall of the dust removal chamber have an air gap, and the body is located at the air gap and slightly higher than the air gap to the water inlet part.

[0025] In actual work, the airflow mixes with water vapor and flows upward from the air gap, and the water vapor entrains dust and separates from the airflow after passing through the water vapor separation member, and then continuously converges and condenses, and falls into the water storage tank from the water vapor separation member. This is the same as the existing self-excited wet dust collector.

[0026] The air gap restricts the flow direction of the airflow, and under the action of the airflow, most of the water splashes are excited upward from the air gap. By arranging the water collecting member such that the body is located at the air gap and the water inlet part is slightly higher than the air gap, the water collecting effect of the water collecting member is better, the detection accuracy of the sensor to the water pressure is higher, and the safety in use is further improved.

[0027] Compared with the prior art, the self-excited wet dust collector fixes the water collecting member in the dust removal chamber, the water collecting member has a body substantially in the form of a pipe and a water inlet part connected to the upper end of the body, the flow area of the water collecting member at the water inlet part is greater than the flow area of the water collecting member at the connection between the water inlet part and the body. During the dust removal process, the water splashes falling under the action of gravity are continuously collected by the water inlet part, and the continuously collected water splashes enter the tubular body to form a continuous flow state, and the water flow generates water pressure. In this way, the sensor can detect the water pressure, and alarm when the detected water pressure value is lower than the set value. Through the above arrangement, the self-excited wet dust collector can monitor the water pressure during work and alarm, thereby improving the safety in use. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0037] The following are specific embodiments of the present application and further describe the technical solutions of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0038] Example 1

[0039] As Figures 1-5As shown, the self-excited wet dust collector comprises a shell 1 having dust collection cavities 1a and dust removal cavities 1b in front and back, the number of dust collection cavities 1a is two and arranged side by side, both of which penetrate the front side of the shell 1, the top of the shell 1 has a through hole communicating with the top of the dust removal cavity 1b, the top of the shell 1 is fixed with a wind guide cover 2, the wind guide cover 2 has an air inlet 2a arranged downward and communicating with the through hole, and an air outlet 2b arranged on the side, the top of the wind guide cover 2 is fixed with a fan 3 and the impeller of the fan 3 is arranged downward in the wind guide cover 2. The water vapor separation piece 4 is fixed in the dust removal cavity 1b, wherein the water vapor separation piece 4 comprises two inclined plates 4a and one of the inclined plates 4a is located above the two inclined plates 4a, the rear end of the lower inclined plate 4a is fixedly connected with the inner wall of the rear side of the dust removal cavity 1b, the front end is inclined downward and the gap between the front end and the inner wall of the front side of the dust removal cavity 1b is provided; the front end of the upper inclined plate 4a is fixedly connected with the inner wall of the front side of the dust removal cavity 1b, the rear end is inclined downward and the gap between the rear end and the inner wall of the rear side of the dust removal cavity 1b is provided. In practice, the number of inclined plates 4a can be increased according to needs.

[0040] Specifically, as shown in Figure 4 and Figure 5 The inner wall of the front side of the dust removal cavity 1b comprises a connecting wall one 1b1, a connecting wall two 1b2 and a connecting wall three 1b3 from top to bottom, the connecting wall one 1b1 and the connecting wall three 1b3 are vertically arranged, the front end of the connecting wall two 1b2 is connected with the lower end of the connecting wall one 1b1 and the rear end of the connecting wall two 1b2 is inclined downward and connected with the upper end of the connecting wall three 1b3, the inclined plate 4a is located in the range of the dust removal cavity 1b where the connecting wall one 1b1 is located, and the front end of the lower inclined plate 4a is located above the connecting wall two 1b2.

[0041] Further, as shown in Figure 4 and Figure 5As shown, the dust removal cavity 1b is further fixed with a connecting plate 5, which is fixedly connected with the left and right inner walls of the dust removal cavity 1b. The front inner wall of the dust removal cavity 1b, the left and right inner walls of the dust removal cavity 1b and the connecting plate 5 jointly form a water storage groove 6 below the water vapor separation piece 4, and the connecting plate 5 and the rear inner wall of the dust removal cavity 1b have an air gap 7. In this embodiment, the rear end of the connecting plate 5 is inclined upward relative to the front end, the water storage groove 6 is specifically formed by the upper side of the connecting plate 5, the left and right inner walls of the dust removal cavity 1b and the connecting wall 3, the air gap 7 is located between the rear end of the connecting plate 5 and the rear inner wall of the dust removal cavity 1b, and the front end of the connecting plate 5 and the connecting wall 3 have a water outlet 8. The shell 1 has a communication port 1c which communicates the bottom of the dust collection cavity 1a and the bottom of the dust removal cavity 1b, the water outlet 8 communicates with the communication port 1c, and the communication port 1c penetrates the connecting wall 3. The lower end of the water storage plate is fixedly connected with a vertically arranged flow guide plate 9, the flow guide plate 9 is located at the communication port 1c and the lower end of the flow guide plate 9 is higher than the lower edge of the communication port 1c.

[0042] In use, water is filled in the shell 1, the water is located at the bottom of the dust removal cavity 1b and the bottom of the dust collection cavity 1a, and the liquid level of the water is ensured to be lower than the upper edge of the communication port 1c. When the fan 3 is started, the airflow is sucked into the dust collection cavity 1a from the outside and enters the dust removal cavity 1b through the communication port 1c along with the dust in the dust collection cavity 1a. The flow rate of the airflow is fast, so that a large amount of water splashes on the water surface, that is, self-excitation. The water mist formed by the water splashes mixes into the airflow and wraps around the dust, so that the airflow mixes with water vapor. The airflow flows to the upper part of the dust removal cavity 1b through the air gap 7, and when the airflow passes through the water vapor separation piece 4, the water vapor mixed in the airflow loses kinetic energy after colliding with the water vapor separation piece 4 and condenses on the surface of the inclined plate 4a (clean air flows out of the air outlet 2b), and the water vapor accumulates into a water flow and flows down along the water vapor separation piece 4. The water separated by the water vapor separation piece 4 falls into the water storage groove 6, and flows down along the side surface of the flow guide plate 9 from the water outlet 8, and finally supplements the communication port 1c to increase the water vapor content in the airflow.

[0043] Further, as shown in FIG. 2, Figure 5 and Figure 6As shown, a water collector 10 is fixed inside the dust collection chamber 1b. The water collector 10 has a generally tubular body 10a and a water inlet 10b connected to the upper end of the body 10a. The flow cross-sectional area of ​​the water collector 10 at the water inlet 10b is larger than the flow cross-sectional area of ​​the water collector 10 at the connection between the water inlet 10b and the body 10a. This wet scrubber also includes a sensor 11 that can detect the water pressure inside the body 10a and an alarm 12 that can sound an alarm when the value detected by the sensor 11 is less than a set value. The flow cross-sectional area of ​​the water inlet 10b gradually decreases from top to bottom. Specifically, the water inlet 10b is funnel-shaped. Alternatively, the water inlet 10b can also be cylindrical or triangular, etc. The water collector 10 is located in the lower part of the dust collection chamber 1b, the body 10a is located at the air gap 7, and the water inlet 10b is slightly higher than the air gap 7.

[0044] Furthermore, such as Figure 6 As shown, a connecting pipe 14 extending out of the housing 1 and communicating with the interior of the body 10a is connected to the side of the body 10a. A sensor 11 is connected to the end of the connecting pipe 14 located outside the housing 1, and the sensor 11 has a digital display function. The flow cross-sectional area of ​​the water collecting component 10 at the upper end of the body 10a is larger than the flow cross-sectional area of ​​the water collecting component 10 at the lower end of the body 10a. Specifically, a plug 13 is connected to the lower end of the body 10a, and the plug 13 has a drain hole 13a. The connecting pipe 14 includes a first pipe body 14a and a second pipe body 14b. The housing 1 has a mounting hole. One end of the first pipe body 14a extends out of the mounting hole and is threaded into one end of the second pipe body 14b. The sensor 11 is connected to the other end of the second pipe body 14b. The outer side of the first pipe body 14a has a shoulder 14a1. The housing 1, where the mounting hole is located, is clamped between the shoulder 14a1 and the end of the second pipe body 14b. The sensor 11 specifically adopts an intelligent pressure controller, and the alarm 12 is integrated into the intelligent pressure controller. Regarding the setting of the set value, in practice, first select a suitable sensor 11 based on the size parameters of the water collection component 10 and the installation height of the water collection component 10. After the water collection component 10 is installed on the housing 1 and connected to the sensor 11, turn on the machine and record the minimum pressure value and the maximum pressure value that the sensor 11 can display. Then select a value slightly larger than the recorded minimum pressure value as the set value.

[0045] The water splashes caused by the airflow flowing over the water surface reach a certain height and then fall down under the action of gravity. The self-excited wet dust collector fixes a water collecting part 10 in the dust removal chamber 1b. The water collecting part 10 has a substantially tubular body 10a and a water inlet part 10b connected to the upper end of the body 10a. The cross-sectional area of the flow passage at the water inlet part 10b is larger than that at the connection between the water inlet part 10b and the body 10a. In this way, the water splashes falling under gravity can be continuously collected by the water inlet part 10b during the dust removal process, and the continuously collected water splashes can enter the tubular body 10a to form a continuous flow state. The water flow will always generate water pressure (just like the state of continuously pumping water into the pipe for continuous delivery). In this way, the sensor 11 can detect the water pressure, and an alarm can be given when the detected water pressure value is lower than the set value. Through the above arrangement, the self-excited wet dust collector can monitor and alarm the water pressure during operation, improving the safety of use.

[0046] Embodiment Two

[0047] The structure and principle of this embodiment are basically the same as those of Embodiment One, except that, as shown in Figure 8 the lower end of the body 10a of the water collecting part 10 is connected with a valve 15. The opening of the valve 15 is adjusted to ensure that the cross-sectional area of the flow passage at the upper end of the body 10a of the water collecting part 10 is larger than that at the lower end of the body 10a, so that a continuous water flow state can be formed in the body 10 during the dust removal process. In this way, the water pressure can always be detected to ensure reliability.

[0048] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.
