A sintering-free sand-washing mud brick, comprising the following components in parts by weight: 50-60 parts of sand-washing mud, 30-45 parts of cement, 5-10 parts of slaked lime, 0-1.1 parts of sodium chloride and 8 parts of water ~19 parts; the sodium chloride accounts for 0-2% of the total amount of cement and slaked lime, and the water accounts for 10-15% of the total amount of solid materials. The sand washing sludge is a powdery material obtained through digestion, grinding and sieving. Preferably, the slaked lime is a powdery material obtained by digesting, drying and grinding quicklime. The invention also discloses a preparation process of the sintering-free sand-washing mud brick. Beneficial effects of the present invention: sand washing silt is used as the main raw material, and the mixing amount can reach 50-60%, which not only solves the problem of stacking river silt, but also solves the problem of farmland damage caused by solid clay bricks; the preparation process is simple and the production cycle is short , to meet the requirements of energy saving and emission reduction; the product has high shape retention and excellent mechanical properties, and can be used instead of ordinary clay bricks.

The invention relates to a two-channel return air air-conditioning case. The two-channel return air air-conditioning case comprises a return fan section, an air exhaust section, a fresh return air mixing section, a filter section A, a surface cooling section, a heating section, a humidifying section, a forced draft fan section, a filter section B and a control air valve. A return air port is formed above the return fan section, the return fan section is connected with the air exhaust section, an air exhaust port is formed above the air exhaust section, the upper section the air exhaust section is connected with the fresh return air mixing section, a fresh air port is formed above the fresh return air mixing section, the fresh return air mixing section is connected with the filter section A, the filter section A is connected with the surface cooling section, a chilled water connector is arranged above the surface cooling section,, and the surface cooling section is connected with the heating section. The lower section of the air exhaust section is connected with the filter section B through a partition pipe, the filter section B is connected with the control air valve, and the control air valve is connected with the heating section. The heating section is connected with the humidifying section, and the humidifying section is connected with the forced draft fan section. The two-channel return air air-conditioning case improves the energy-saving potential of an air-conditioning system and meets the energy-saving and emission-reducing requirements.

The invention discloses a production process of a foaming headset sleeve, and the production process comprises the following steps of a, preparation of materials: placing a well mixed material A and a well mixed material B respectively into a mixing kettle to be stirred; b, mixing: simultaneously placing the material A and the material B into the mixing kettle to be adequately stirred and mixed to form a mixed material; c, injection: continuously injecting the mixed material into a plurality of molds which are matched with each headset sleeve in shape through a mixing reaction kettle, arranging the molds in a single row in the transverse direction, and realizing automatic circular work through a transmission device; d, baking: automatically feeding the molds with the mixed material into a baking box to be baked through the transmission device; and e, demolding: pouring out the headset sleeves from the molds through the transmission device so as to enable the headset sleeves to be separated from the molds after baking is completed. Compared with the prior art, the production process of the foaming headset sleeve has the advantages of simplicity in production equipment, few in manufacturing procedures, simplicity in mold structure, long in service life, capability of being formed in one step, good forming quality, low production cost and low energy consumption.
