Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a settling chamber structure for cutting and dust removal. Background Art

[0002] In various industrial productions, cutting machines are used very frequently and involve a wide range of fields. The use of various types of cutting machines will lead to a significant increase in their dust content, and the dust particles they generate are of different sizes and high density. In order to solve the larger particles in the dust, a sedimentation chamber structure for cutting dust removal has been derived.

[0003] Existing sedimentation chambers are usually arranged horizontally and need to be blocked by multiple layers of baffles. If they are manufactured according to existing specifications, in order to meet the requirements of on-site equipment, the manufactured size will be too long and the installation area will be large. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a settling chamber structure for cutting and dust removal.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A settling chamber structure for cutting and dust removal includes a casing, which is provided with an air inlet and an air outlet. A plurality of baffles are arranged side by side in the casing, and a dust-blocking channel extending vertically and having at least one bend is formed between adjacent baffles. The air inlet is connected to the air inlet end of the dust-blocking channel, and the air outlet is connected to the air outlet end of the dust-blocking channel.

[0007] A partition is provided inside the casing, which separates the interior of the casing into a dust reduction chamber and a circulation chamber connected from the top. Several baffles are provided in the dust reduction chamber, the air inlet is connected to the dust reduction chamber, and the air outlet is connected to the circulation chamber. The volume of the circulation chamber is smaller than the volume of the dust reduction chamber.

[0008] The air outlet is communicated with the bottom of the circulation chamber.

[0009] An inclined plate is obliquely arranged in the circulation chamber, and the inclined plate is used to guide the air flow to be discharged from the air outlet.

[0010] Both ends of the baffle are fixed by support members.

[0011] A circular arc plate is further provided in the circulation chamber, and the circular arc plate is used to guide the air flow to be discharged from the air outlet.

[0012] The support member includes a fixing plate with a supporting space formed by bending.

[0013] The support member includes a first connecting plate and a second connecting plate that are separately arranged. The first connecting plate is a bent member, and a supporting space is formed between the first connecting plate and the second connecting plate.

[0014] The casing is formed by splicing together a number of splicing plates.

[0015] The bottom of the casing is funnel-shaped, and the discharge port of the casing is opened at the bottom of the casing.

[0016] The beneficial effects of the present invention are as follows: dust-laden exhaust gas enters the casing from the air inlet, and due to the sudden and substantial increase in ventilation area, the overall wind speed rapidly decreases, and the wind direction passes vertically upward through the dust blocking channel, so that larger dust particles will find it difficult to overcome the effect of gravity and fall downward and settle at the bottom of the settling chamber. In addition, some larger dust particles will enter the dust blocking channel, but will be stopped at the bend of the dust blocking channel, and will then be deposited at the bottom of the settling chamber under the action of gravity. Compared with the prior art, the present invention achieves the purpose of blocking larger dust particles through a number of vertically arranged baffles, and the lateral dimensions of the casing are controlled, thereby reducing the floor space occupied by the settling chamber.

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0024] like Figures 1 to 5 The structure of a settling chamber for cutting dust removal is shown in FIG. The structure includes a housing 1 with an air inlet 2 and an air outlet 3 formed on the housing 1, and a discharge port formed at the bottom. For example, a dust removal device can be connected to the air outlet 3. When the dust removal device's fan is activated, dust-laden air can be drawn into the housing 1 through the air inlet 2 for settling.

[0025] To improve the sedimentation effect, a plurality of baffles 4 are arranged side by side within the housing 1. The baffles 4 can be made of sheet metal with a wavy cross-section. Thus, a dust-blocking channel 5 extending vertically and having a bent portion can be formed between adjacent baffles 4. It will be understood that the dust-blocking channel 5 having multiple bent portions can be formed by bending the baffles 4 multiple times. The number of bends of the baffles 4 is not limited in this embodiment.

[0026] Accordingly, the air inlet 2 is connected to the air inlet end of the dust-blocking duct 5, while the air outlet 3 is connected to the air outlet end of the dust-blocking duct 5. Therefore, when dust-laden air enters the housing 1, the ventilation area suddenly and significantly increases, causing the overall wind speed to rapidly decrease, and the wind direction passes vertically upward through the dust-blocking duct 5. As a result, larger dust particles will find it difficult to overcome gravity and will fall downward and settle at the bottom of the settling chamber. Furthermore, some larger dust particles will be carried by the airflow into the dust-blocking duct 5, but will be stopped at the bend in the dust-blocking duct 5 and subsequently, under the action of gravity, will settle at the bottom of the settling chamber.

[0027] For example, the bottom of the casing 1 can be constructed in a funnel shape, which is more conducive to the collection of settled dust; a dust discharge valve, a plug valve, etc. can be set at the discharge port to facilitate the discharge of dust.

[0028] In some embodiments, a partition 6 is provided in the casing 1, and the interior of the casing 1 is separated by the partition 6 into a dust reduction chamber 7 and a circulation chamber 8 connected from the top. Among them, a number of baffles 4 are provided in the dust reduction chamber 7, the air inlet 2 is connected to the dust reduction chamber 7, and the air outlet 3 is connected to the bottom of the circulation chamber 8. Therefore, the dust-laden airflow can flow along the air inlet 2, the dust blocking channel 5, the circulation chamber 8 and the air outlet 3 under the action of the fan. In addition, it is also preferred that the volume of the circulation chamber 8 is smaller than the volume of the dust reduction chamber 7. At this time, when the airflow passes through the dust blocking channel 5 and enters the circulation chamber 8, the wind speed will suddenly increase due to the sudden and substantial reduction in the ventilation area, and be discharged from the air outlet 3 from top to bottom. In other words, after the airflow completes the dust sedimentation in the dust blocking channel 5, it can increase the wind speed again in the circulation chamber 8, thereby improving the efficiency of dust removal.

[0029] For example, an inclined plate 9 is also tiltedly provided in the circulation chamber 8, and an arc plate 11 is also provided in the circulation chamber 8. Both the inclined plate 9 and the arc plate 11 can receive the airflow flowing from top to bottom, and guide the airflow to the air outlet 3 for discharge.

[0030] In some embodiments, the upper and lower ends of the baffle 4 are supported and fixed by support members 10. For example, the support member 10 can be a fixed plate 12 formed by bending to form a support space. Alternatively, the support member 10 can be a first connecting plate 13 and a second connecting plate 14, each of which is a bent member and defines a support space between them. Both types of support members 10 can be used to support the ends of the baffle 4, and a combination of the two can also be used.

[0031] The bottom end of the baffle 4 is supported and fixed by the fixing plate 12 , and the top end of the baffle 4 is supported and fixed by two connecting plates.

[0032] For example, the housing 1 can be formed by joining together a plurality of splicing plates 15. Specifically, the housing 1 as a whole can include, from bottom to top, a first base, a first side surface, a second base, a second side surface, and a top surface. The first side surface, the second side surface, and the top surface can all be formed by joining together a plurality of connecting plates.

[0033] In a preferred example, square tubes are provided at both ends of the baffle 4 in the casing 1, and the support members 10 at both ends of the baffle 4 are respectively provided on corresponding square tubes, which makes it easier to position and install the support members 10.

[0034] The utility model uses a sheet metal structure for pre-treatment, effectively separates and collects large particles of dust in the dust-laden exhaust gas, and the dust-laden exhaust gas that subsequently flows into the dust removal equipment has low content and is all small particles, which can effectively increase the service life of the dust removal equipment, increase the service life of the filter element and extend the replacement cycle of the filter element, directly reduce the maintenance cost, have obvious effects, and further improve the working environment and the safety of the equipment.

[0035] In a preferred embodiment, one of the aforementioned square tubes can be vertically slidable within the dust suppression chamber 7 via a sliding member such as a slide rail, and a material reduction groove is provided at the bend of the baffle 4, thereby facilitating rotation of the baffle 4 at the bend. It will be appreciated that the sliding of the square tube can cause the angle of the bend of the baffle 4 to change, thereby adjusting the speed of airflow through the dust blocking passage 5, ultimately achieving adjustment of both the dust suppression effect and the dust suppression speed.

[0036] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant fields. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
