[0020] Reference Figure 1-7 As shown, a sand-removing air purification unit includes a casing 1, a rain-sand separation component 2, a fine sand separation component 3, and a pre-filter component 4. The rain-sand separation component 2 is located at the front inlet of the casing 1. The fine sand separation component 3 and the pre-filter component 4 are sequentially arranged inside the casing 1. The rain-sand separation component 2 has a mounting frame 21 and louvers 22. The mounting frame 21 is fixed to the front end of the casing 1, and the louvers 22 are arranged in a louvered structure within the mounting frame 21. The fine sand separation component 3 has a fixing strip 31 and a "J"-shaped barrier 32. The fixing strip 31 is horizontally fixed inside the casing 1, and the "J"-shaped barrier 32... The J-shaped barrier plates 32 are vertically spaced on the fixing strip 31. The fine sand separation component 3 has at least two rows of J-shaped barrier plates 32 arranged in front and behind, and the front and rear groups of J-shaped barrier plates 32 are staggered. The primary filter component 4 is provided with a fixing frame 41, a primary filter screen 42, a sliding guide rail 43 and a dust removal brush 44. The fixing frame 41 is located in the housing 1 downstream of the fine sand separation component 3. The primary filter screen 42 is laid on the fixing frame 41. The sliding guide rail 43 is located on at least one side of the primary filter screen 42, either upstream or downstream. The dust removal brush 44 is located on the slider of the sliding guide rail 43 and is fitted to the primary filter screen 42.
[0021] The unit is divided into three parts: the front section blocks coarse sand and rainwater, the middle section blocks fine sand, and the end section blocks coarse dust and large particles. The front-end rain and sand separator consists of double-row louvered windbreak panels 23 arranged at a certain angle, which can be connected to an external duct to block rainwater and coarse sand. The middle section fine sand separator module consists of double-row distributed J-shaped sand-proof sheets arranged in an alternating pattern, with a sand and dust collection box 51 at the bottom for connection to a dust pump. The rear section is a pre-filter to block larger dust particles floating in the air, and is equipped with XY-axis track-driven dust removal brushes 44 to scrape dust and sand into the bottom collection box 51, achieving a self-cleaning effect. The unit can be equipped with a fan. This utility model features a three-stage filtration system, effectively blocking rainwater, coarse sand, and dust, and has a self-cleaning function, making it suitable for harsh industrial environments.
[0022] The louver 22 and the "J"-shaped barrier 32 are integrally formed or spliced together.
[0023] The rain and sand separation component 2 is composed of rain and sand filter louvers 22. The louvers 22 are tilted at an angle of 45 degrees and are fixed to the mounting frame 21 by bolts 28. They physically block rainwater and coarse sand from entering the unit.
[0024] The fine sand separation component 3 consists of two sets of J-shaped wind deflectors. The hooks on the deflectors facilitate the swirling and falling of fine sand, and a double-layer wind deflector is provided. At the same time, three sets of fixing strips 31 are provided at the front, middle and rear, and the J-shaped wind deflectors are assembled through screw locking holes.
[0025] The rear section is a primary metal filter with a self-cleaning scraper to block fine dust particles. The self-cleaning device is an XY axis slide rail with a long brush head. After cleaning, the dust falls into the dust collection box at the bottom of the unit. The sliding guide rail 43 can move horizontally or vertically, driving the dust removal brush 44 to clean the dust on the primary filter 42. The sliding guide rail 43 and the dust removal brush 44 can be set on the upstream side, downstream side, or both sides of the primary filter 42. In order to save costs and ensure cleaning effect, the sliding guide rail 43 and the dust removal brush 44 are set on the upstream side of the primary filter 42, where cleaning is more difficult on the windward side. When both sides are set, the sliding guide rail 43 and the dust removal brush 44 on both sides can be horizontal or vertical scrapers, or one side can be horizontal and the other side can be vertical. Both sides can scrape simultaneously, or move forward and backward or relative to each other.
[0026] Furthermore, a sand collection hopper 5 is provided below the fine sand separation component 3 and the primary filter component 4, respectively.
[0027] The sand collection bucket 5 is used to collect the sand and dust separated from the internal structure of the casing 1. The sand and rainwater separated by the rain-sand separation component 2 are usually directly piled up below or outside the casing 1 and cleaned regularly. Larger sand and gravel have little impact on the operation of the equipment.
[0028] Furthermore, the lower end of the sand collection hopper 5 is connected to a sand suction pipe or a collection box 51, the sand suction pipe is connected to a blower, and the collection box 51 is detachably connected to the sand collection hopper 5.
[0029] A sand collection hopper 5 is installed at the bottom of the unit. The opening of the sand collection hopper 5 is rectangular and fixed to the bottom of the unit. The bottom is conical and can be connected to the exhaust pipe to discharge sand or stored in the collection box 51.
[0030] Furthermore, the mounting frame 21 is provided with louver blades 22 with a front and rear double-layer louver structure.
[0031] The louvers 22 of the rain and sand separation component 2 can be placed vertically or horizontally.
[0032] Furthermore, the louver 22 is provided with a wind deflector 23, a connecting plate 24 and a sand deflector 25. The connecting plate 24 is located at both ends of the wind deflector 23 at an obtuse angle and is vertically arranged. The sand deflector 25 is connected to the connecting plate 24 at the downstream end. The sand deflector 25 is an acute-angle plate, a right-angle plate or an arc-shaped plate.
[0033] After the sand and sand pass through the windbreak plate 23, the sand and gravel are blocked by the sand baffle plate 25 and fall to the bottom by gravity.
[0034] Furthermore, at least the downstream side of the wind deflector 23 or the connecting plate 24 is provided with a screw hole post 26.
[0035] At least the wind deflector 23 or the connecting plate 24 can be either the wind deflector 23, the connecting plate 24, or both. The louvers 22 are then fixedly mounted to the mounting frame 21 using screws, which pass through the side of the mounting frame 21 and connect to the screw post 26. The screw post 26 reinforces the wind deflector 23.
[0036] Furthermore, the connecting plate 24 is provided with bolt holes 27, the front and rear connecting plates 24 are connected by bolts 28, and the bolts 28 between the connecting plates 24 are fitted with separator sleeves 29.
[0037] The adjacent layers of each louver 22 are connected by bolts 28 to form a double-row louver structure. This structure can also be installed after the frame 21 is assembled outside, which is convenient for assembly.
[0038] Furthermore, the angle of the baffle plate 23 is 40°-50°; preferably 45°. This angle provides better separation and reduces the impact on subsequent separation and filtration.
[0039] Furthermore, the "J"-shaped barrier plate 32 is provided with a wind guide plate 33, a wind baffle plate 34 and a swivel plate 35. The wind guide plate 33 is connected to the wind baffle plate 34. The wind baffle plate 34 is an "L"-shaped plate. The swivel plate 35 is connected to the other side of the wind baffle plate 34. The swivel plate 35 is a semi-circular plate.
[0040] Fine sand has low gravity, so a swirling plate 35 is needed for further separation.
[0041] Furthermore, the front end of the air guide plate 33 is provided with a mounting plate 36, which is perpendicular to the air guide plate 33. The mounting plate 36 and the wind baffle plate 34 are respectively connected to the fixing strips 31 on the front and rear sides. The diameter of the swirling plate 35 is 1 / 3 to 2 / 3 of the height of the "L"-shaped plate; it is usually set to 1 / 2.
[0042] The diameter of the rotary plate 35 is 1 / 3 to 2 / 3 of the height of the "L"-shaped plate, which means that the opening height of the rotary plate 35 is 1 / 3 to 2 / 3 of the height of the "L"-shaped plate.
[0043] The mounting plate 36 serves two purposes: firstly, it connects the "J"-shaped barrier plates 32 to the fixing strips 31; secondly, it blocks the gaps between the front "J"-shaped barrier plates 32, reducing the direct entry of sand and dust into the rear fine sand separation assembly 3, thus achieving two-stage separation of fine sand and improving the separation effect. Without the mounting plate 36, the fixing strips 31 at the front end of the "J"-shaped barrier plates 32 can be parallel to the length of the air guide plate 33 and connected to the air guide plate 33 at the position of the mounting plate 36, achieving the same effect.
[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
