Problems solved by technology

[0002] In the northwestern region of our country, the climate is dry and noisy, and the wind and sand are strong in spring and autumn. The use of central air-conditioning air handling units in this area is a very big test for its filtration system. The filtration system needs to be replaced frequently, which increases maintenance costs and maintenance costs. It is a common way to install a sand removal device at the air inlet, but the current sand removal device also has certain shortcomings, the sand removal rate is relatively low, and the sand removal performance needs to be improved

Embodiment

[0021] Such as Figure 1-3 As shown, a fresh air sand removal device includes an air inlet 1, a sand removal box 2, a sand shield assembly 4, a sand collection tank 5, and an air outlet 3. The air inlet 1 can be a rain-shielding louver air inlet, so Said sand baffle assembly 4 is arranged above the sand collection tank 5, said sand baffle assembly 4 includes several sand baffles 41 arranged together, and a curved air duct 42 is formed between adjacent sand baffles 41, specifically The sand-blocking plate 41 is a wave-shaped sand-blocking plate, and the two sides of the sand-blocking plate 41 are provided with several arresting grooves 43, and the arresting grooves 43 are arranged on the peaks and valleys of the wave-shaped sand-blocking plate At the place, the curved air duct 42 and the blocking ditch 43 can effectively reduce the wind speed, and can effectively block most of the dust and sand.

[0022] Specifically, the sand baffle assembly 4 also includes a fixed sleeve 44 ...

Abstract

The invention belongs to the technical field of central air conditioner air treatment, and particularly relates to a fresh air sand removing device. The fresh air sand removing device comprises an air inlet, a sand removing box body, a sand baffle assembly, a sand collecting groove and an air outlet, wherein the sand baffle assembly is arranged above the sand collecting groove and comprises a plurality of sand baffles arranged together, and a curved air duct is formed between every adjacent sand baffles. According to the fresh air sand removing device, the innovative sand baffle assembly structure can greatly improve the sand blocking rate and the sand removing rate, the curved air ducts and blocking ditches can effectively reduce the air speed, and most dust and sand can be effectively blocked, so that the sand removing effect is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of central air-conditioning air treatment, and relates to a fresh air sand removal device. Background technique [0002] In the northwestern region of our country, the climate is dry and noisy, and the wind and sand are strong in spring and autumn. The use of central air-conditioning air handling units in this area is a very big test for its filtration system. The filtration system needs to be replaced frequently, which increases maintenance costs and maintenance costs. It is a common way to install a sand removal device at the air inlet end, but the current sand removal device also has certain shortcomings, the sand removal rate is relatively low, and the sand removal performance needs to be improved. Contents of the invention [0003] The invention provides a fresh air sand removal device, which can solve the problems pointed out in the background technology. [0004] A fresh air sand removal device, co...
