Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal, and in particular relates to a wet grinding dust removal device. Background Art

[0002] A dust removal device is a device that removes particulate matter from the gas and is used to purify the air. A large amount of flying chips are generated during the grinding process of the workpiece. Therefore, a large amount of solid particulate matter is generated in the dust-laden gas generated during the grinding process. For this reason, a dust removal device is required to perform dust removal operations. There are various types of dust removal devices in the existing technology, such as bag dust collectors, cyclone dust collectors, and wet dust collectors. Wet dust collectors use the principle of water adsorption of particulate matter to remove dust. Therefore, wet dust collectors are widely used in the field of grinding technology for dust removal operations.

[0003] There are various types of wet dust collectors in the prior art. For example, Chinese utility model patent CN210522079U discloses an internal cleaning structure of a water vapor separation device and a wet dust collector. The dust collector includes a shell, a fan, a water vapor separation device, and a water pump. During dust removal, the dust-laden gas is introduced into the dust removal device by the fan, and then water is pumped by the water pump for spraying. When the dust collector is performing dust removal, the water pump sprays water to adsorb particulate matter in the dust-laden gas, thereby achieving the purpose of dust removal. The moisture in the gas is then removed by the water vapor separation device, and the dust-removed gas is discharged.

[0004] Although the dust removal device can spray and absorb particulate matter in the dust-laden gas, due to the large amount of flying chips generated in the field of grinding technology, when the flying chips with larger particles enter the dust collector due to the gravity of the fan, the flying chips can be retained in the dust collector by spraying. However, due to the large size of the particles, the sewage outlet of the dust collector is easily blocked, resulting in difficulty in discharging the sludge in the dust collector, thereby causing inconvenience in the use of the dust collector.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0037] like Figure 1-2 As shown, it is a structural diagram of the wet grinding dust removal device in this embodiment. The dust removal device in this embodiment adopts a wet dust removal method and is applied in the field of grinding technology. It is used to remove dust from the dust-containing gas generated during the grinding process to avoid the problem of air pollution caused by the dust-containing gas discharged into the atmosphere.

[0038] The dust removal device in this embodiment uses a wet dust removal method to remove dust. Specifically, water is injected into the dust removal device, and the introduced dust-laden gas contacts the water. The water can adsorb the particulate matter in the dust-laden gas, remove the gas emissions of the particulate matter, and thus achieve dust removal.

[0039] like Figure 1 As shown, the dust removal device in this embodiment includes a shell 100, an air inlet unit 101 is provided on one side of the shell 100, and an air induced draft component 103 is provided on the top of the shell 100. The air induced draft component 103 is used to introduce the dust-laden gas into the shell 100 through the air inlet unit 101. Water is injected into the shell 100. When the dust-laden gas contacts the water, the water can adsorb the particulate matter in the dust-laden gas, thereby achieving dust removal.

[0040] like Figure 1-3 As shown, in this embodiment, a water tank 102 is installed on one side of the shell 100, the water tank 102 is connected to the shell 100, and the water tank 102 has a built-in liquid level sensor for monitoring the liquid level position of the water in the water tank 102. In this embodiment, a water storage tank is provided at the bottom of the shell 100, and the water storage tank is connected to the water tank 102. The water in the water tank 102 enters the water storage tank to adsorb particulate matter in the dust-laden gas.

[0041] like Figure 4 As shown, when the induced draft component 103 is working, the dust-laden gas is introduced into the water tank through the air inlet unit 101 to contact with water, and the water adsorbs the particles in the dust-laden gas. In order to prevent large particles of flying debris from entering the dust removal device and clogging the sewage outlet, in this embodiment, as shown in FIG. Figure 5 As shown, the air inlet unit 101 includes an air inlet 101a, and a filter plate 101b is provided at the bottom of the air inlet 101a. The filter plate 101b is located above the water tank. When the air induced component 103 is in operation, the dust-laden gas is introduced into the shell 100. During the introduction process, the dust-laden gas passes through the filter plate 101b in the air inlet 101a. The filter plate 101b intercepts large particles of flying debris in the dust-laden gas to achieve the purpose of preliminary filtration, thereby avoiding the problem of large particles of flying debris entering the dust removal device and causing the sewage outlet to be blocked.

[0042] In addition, if Figure 3 as well as Figure 4 As shown, a guide portion 104 is provided at the bottom of the water tank in this embodiment. The guide portion 104 is an arc-shaped structure, and the water tank is connected to the water tank 102. When the dust-laden gas enters the water tank and comes into contact with water, the water absorbs the particulate matter in the dust-laden gas, and the particulate matter settles to the bottom of the water tank. The pollutants can be introduced into the water tank 102 through the arc-shaped guide portion 104 and then discharged through the sewage outlet.

[0043] In addition, if Figure 6As shown, in this embodiment, in order to further ensure the dust removal effect of the dust removal device, the shell 100 in this embodiment is equipped with a partition assembly 200. The partition assembly 200 divides the inner cavity of the shell 100 into two chambers, namely the inner cavity and the outer cavity. The outer cavity is connected to the air inlet unit 101. When the air induced assembly 103 is working, the dust-laden gas is preliminarily filtered through the air inlet unit 101 and introduced into the outer cavity and then into the water storage tank. The water in the water storage tank preliminarily adsorbs the dust-laden gas, and a channel for gas to pass through is formed between the partition assembly 200 and the liquid surface of the water storage tank. When the dust-laden gas passes through the channel, the flow rate is faster, so that the water in the water storage tank flows and collides with the partition assembly 200 to generate water splashes. The water splashes further contact the dust-laden gas to further adsorb the particulate matter in the dust-laden gas, thereby improving the dust removal effect of the dust removal device.

[0044] like Figure 8 As shown, the baffle assembly 200 in this embodiment includes a fixed plate 201, and fixed teeth 201a are distributed at the bottom of the fixed plate 201. A channel for gas to pass through is formed between the fixed teeth 201a and the liquid surface of the water storage tank. When the dust-laden gas passes through the channel, the water collides with the fixed teeth 201a due to the fast flow rate to generate water splashes, which adsorb particulate matter in the dust-laden gas.

[0045] In addition, the gas after dust removal has high humidity due to contact with water. In order to avoid the discharge of gas with high moisture content, the dust removal device in this embodiment is also provided with a demisting component, which removes moisture from the gas. Figure 6 as well as Figure 7 As shown, the demisting assembly includes a guide plate 202 obliquely mounted on a fixed plate 201, a through hole 202a is provided at the connection between the guide plate 202 and the fixed plate 201, and a guide plate 203 is installed on the other side of the fixed plate 201 relative to the guide plate 202, a cavity is formed between the guide plate 203 and the fixed plate 201, the through hole 202a is connected to the cavity, and a guide groove 203a is provided at the bottom of the guide plate 203, the guide groove 203a is used to direct the water in the cavity to flow back to the surface of the fixed plate 201 and then drain it into the water storage tank.

[0046] In this embodiment, when the gas containing moisture contacts the fixed plate 201, the moisture condenses on the surface of the fixed plate 201 to form water droplets. The water droplets gather to form a water flow that passes through the through hole 202a and enters the cavity of the guide plate 203, and then is drained to the surface of the fixed plate 201 through the guide groove 203a and enters the water storage tank. The moisture in the gas can be removed by setting the demisting component. Therefore, the dust removal device in this embodiment can remove dust and moisture from the dust-containing gas and then discharge it, avoiding the problem of air pollution.

[0047] In addition, if Figure 1 as well as Figure 2As shown, the induced draft component 103 in this embodiment includes a fan and a silencer 103a installed on the fan exhaust pipe. The fan in this embodiment can introduce dust-laden gas into the housing 100 for dust removal and discharge it through the exhaust pipe. Since the fan generates huge noise during operation, in order to avoid noise pollution, in this embodiment, a silencer 103a is installed on the fan exhaust pipe. The silencer 103a silences the noise generated when the gas is discharged, thereby avoiding the problem of noise pollution.

[0048] In addition, the side wall of the shell in this embodiment is also equipped with components such as a control panel and a pressure gauge. The control panel is used to control the operation of the draft assembly 103, and the pressure gauge is used to monitor the pressure inside the shell 100. This structure belongs to conventional technology in this field and will not be repeated in this embodiment.

[0049] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
