Abstract

The utility model relates to a water washing device for wood chip, comprising a washing machine and a screw dewatering mechanism whose feed inlet faces the discharge hole of the washing machine. In the shell of a screw dewatering machine, water filter holes of a water filter sieve are column aspect holes. The utility model breaks the traditional ideas in which the wood chip is put into a front pump bin after coming out from the washing machine, and pumped to the screw dewatering machine by a wood chip pump. The wood chip which comes out from the washing machine gets into the screw dewatering machine directly, and is washed again in the process of the screw dewatering machine. Because of leaving out the technology in which the wood chip is put into the front pump bin and pumped to the screw dewatering machine, the utility model saves the energy source greatly. The installed gross capacity is reduced by 50 percent. The power consumption is decreased by 50 percent. The technology can also reduce the wood chip consumption by 90 percent. Because of the compact technology, the utility model is easy to control. The failure rate drops down greatly. The water washing device for wood chip is more compact with less investment which is 2/3 of the original investment. The water washing device for wood chip has a compact structure, a low energy consumption, a low cost and a simple process.

Description

Chip washing equipment

(1) technical field:

The utility model relates in the building board production process, the chip washing equipment when cleaning wood chip.

(2) background technology:

Make make plate the time, must earlier the wood chip as raw material be cleaned, impurity such as the silt in the wood chip, sandstone, ironware, iron fourth are washed, then the moisture content in the wood chip is removed, pass through some Transport Machinery again, washed wood chip is sent in the defibrator, carried out defibrator process, thereby prepare wood fibre.When cleaning wood chip, be in order to reduce the loss of impurity, to reduce power consumption of the mill simultaneously, improving fiber quality on the other hand, the moisture content of stable fibers on the one hand to the grinding machine mill.Existing chip washing equipment comprises rinsing machine, and charging aperture is connected to the bin before pump of rinsing machine discharging opening and is located at the wood chip pump of bin before pump discharging opening, and the charging aperture of spiral dewater is connected to the discharging opening place of wood chip pump.Because the wood chip pump is when the pumping wood chip, not only need a large amount of water, it is also very big consume energy, and the wood chip pump that rotates at a high speed also can damage a large amount of wood chips, causes the waste of wood chip.

(3) utility model content:

The utility model will disclose a kind of simple in structure, and it is little to consume energy, to the almost undamaged chip washing equipment of wood chip.

The utility model and existing chip washing equipment difference be, it is made of rinsing machine and the charging aperture spiral dewater over against the rinsing machine discharging opening.

The difference of the utility model and existing chip washing equipment is that also in the shell of spiral dewater, the treatment hole on the set drainage screen cloth is a cylindrical hole.

After the utility model has been broken tradition thought that wood chip comes out from rinsing machine, must enter bin before pump, and, allow the wood chip that from rinsing machine, comes out directly enter spiral dewater through the traditional concept of wood chip pump pump to spiral dewater, allow wood chip in the process of dewaterer, be cleaned once more.

Because utility model has been saved wood chip has been sent into bin before pump, and be pumped to the technology of spiral dewater with the wood chip pump, and therefore greatly saved the energy, total installation of generating capacity has reduced 50%, power consumption reduces by 50%, and this technology also can reduce the wood chip waste more than 90%.Because technology is succinct, therefore control is convenient, and fault rate declines to a great extent, and equipment is more succinct, and equipment investment reduces, less than original 2/3.

This device structure is succinct, less energy consumption, and cost is low, handling ease.

Fig. 1 is a kind of embodiment structural representation of the present utility model;

Fig. 2 is a spiral dehydration pump structural representation;

Fig. 3 is the A-A view of Fig. 2.

(5) specific embodiment:

In the embodiment of chip washing equipment shown in Figure 2, the charging aperture of spiral dewater 2 is over against the discharging opening of rinsing machine, when wood chip be input to clean in the rinsing machine 1 after, come out from rinsing machine 1 discharging opening, directly, enter in the spiral dewater 2 from the charging aperture of spiral dewater 2.In the shell 23 of spiral dewater 2, be provided with drainage screen cloth 21, drainage screen cloth 21 is provided with treatment hole 22, and treatment hole 22 is a cylindrical hole, and promptly treatment hole 22 inside and outside sizes are identical.

Claims

1, chip washing equipment is characterized in that: it is made of rinsing machine (1) and the charging aperture spiral dewater (2) over against rinsing machine (1) discharging opening.

2, chip washing equipment according to claim 1 is characterized in that: the treatment hole (22) in described spiral dewater (2) shell (23) on the set drainage screen cloth (21) is a cylindrical hole.
