Problems solved by technology

Untreated sea sand contains shells, and the mixture of sea sand and shells is a heterogeneous mixture. The main component of shells in sea sand is CaCO3. Although shells are inert materials, they generally do not chemically react with cement, but these light substances often It is in the form of thin flakes with smooth surface, low strength, easy to crack alo

Embodiment Construction

[0040] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific implementation devices in conjunction with the accompanying drawings.

[0041] Such as Figure 1-3 As shown, a sea sand and shell separation device mainly includes a pressurized water tank 3 and a sand collection tank 7, and the pressurized water tank 3 and the sand collection tank 7 are adjacent to each other.

[0042] The top of the pressurized water tank 3 is provided with a "V"-shaped baffle 1, the "V"-shaped baffle 1 is fixedly connected with the inner wall of the pressurized water tank 3, and the length of the "V"-shaped baffle 1 is less than the length of the inner cavity of the pressurized water tank 3, so The rear end of the "V" type baffle plate 1 can form a sand inlet 2 with the inner wall of the rear end of the pressurized water tank 3 . Both sides of the top of the pressurized water tank 3 have a water outl...

Abstract

The invention relates to a sea sand and shell separating device. The sea sand and shell separating device comprises a sand collecting pool and a water pressing tank adjacent to the sand collecting pool. A baffle is arranged at the top of the water pressing tank, and a sand inlet is formed between the rear end of the baffle and the inner wall of the rear end the water pressing tank. Water outlets are formed in both sides of the top of the water pressing tank. A sand sliding plate arranged obliquely is fixed to the circumference of the inner wall of the middle part of the water pressing tank, and through holes penetrating up and down in a communication mode are densely distributed in the vertical direction of the sand sliding plate. A sand outlet is further formed in the joint between the water pressing tank and the sand collecting pool, the sand outlet is not lower than the lowest end of the sand sliding plate, and the water pressing tank is in communication with the sand collecting pool through the sand outlet. A water inlet is further formed in the bottom of the water pressing tank, and the water pressing tank communicates with a water inlet pipe through the water inlet. A sea sand and shell mixture can be separated by using the sea sand and shell separating device.

Description

technical field [0001] The invention relates to a separation device, in particular to a separation device for sea sand and shells. Background technique [0002] In architectural decoration and engineering construction, placer is an indispensable raw material, but with the economic development in recent years, the demand for placer is increasing, and sea sand is relatively cheap, which has become another choice for people. Untreated sea sand contains shells, and the mixture of sea sand and shells is a heterogeneous mixture. The main component of shells in sea sand is CaCO3. Although shells are inert materials, they generally do not chemically react with cement, but these light substances often It is flake-like, with a smooth surface, its own strength is very low, and it is easy to crack along the joints, and its bonding ability with cement slurry is very poor, so its content must be limited. The apparent density of sea sand is about 2650kg / m3, and the apparent density of she...
