Description

Novel shell structure of wood chip rinsing machine and wood chip rinsing machine

Technical Field

The utility model relates to a papermaking equipment technical field especially relates to an equipment that carries out water washing to wood chip.

Background

In the domestic papermaking industry at the present stage, wood is used as a raw material for pulping, and a large part of the proportion is still occupied. In the process of treating the raw materials, the cut wood chips must be cleaned, so that the abrasion of subsequent equipment caused by impurities in the wood chips is avoided, and unnecessary maintenance cost and downtime are increased.

The principle adopted by the traditional wood chip cleaning method is mostly that the density of wood chips is lower than that of water, and the wood chips can always float on the upper layer of the water in the water. The washing water mixed with the wood chips is stirred to the discharge port by the rotation of a rotor with a plurality of stirring sheets, and the wood chips are separated from impurities such as stones, iron wires and the like under the stirring action of the rotor, slowly settle to the bottom of the shell and are discharged through two gate valves which are opened intermittently.

The structure of the existing wood chip washing machine is shown in figure 1, wood chips enter the washing machine from a feed port 1, and the wood chips always float on the surface of washing water because the density of the wood chips is less than that of water. When the wood chips pass through the rotor 6 with the poking piece, the rotor 6 is continuously rotated and stirred to remove impurities and pollutants contained in the wood chips, metal, stones and the like contained in the impurities are precipitated to the slag discharge port 4, and after the impurities are accumulated to a certain amount, the impurities are discharged by the gate valve 5. At this time, the wood chips come to the discharge port side. Because the liquid level 3 in the washing machine is always higher than the highest point of the baffle 7 at the discharge hole, the washing water can easily drive the wood chips to enter the next procedure along the discharge chute 8. Meanwhile, in order to maintain the liquid level 3 in the washing machine, water is injected into the washing machine continuously through the water injection port 2.

The wood chip washing machine is simple in structure and can meet production requirements. However, since the wood chips are discharged by the washing water, it is necessary to continuously inject new washing water into the housing. Meanwhile, the discharged washing water needs to be treated by subsequent equipment for reuse, but the equipment investment and the loss are increased undoubtedly, and the reduction of the production cost is not facilitated.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve the problem among the prior art, provide a shell structure and wood chip rinsing machine of novel wood chip rinsing machine.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model provides a shell structure of novel wood chip rinsing machine, includes the casing and locates the discharge gate of casing one side, forms the washing pond in the casing, is equipped with the rotor that has the plectrum with the washing pond cooperation, the washing pond is equipped with the weir plate with the discharge gate junction, and the top of weir plate is the arc structure, and the top of weir plate is a little higher than or maintains the water level in the washing pond.

A water filling port is arranged above the water washing pool, a liquid level sensor is arranged in the water washing pool, when the liquid level is lower than the required liquid level, the liquid level sensor sends a signal, and the water filling port starts to fill water.

The top of the shell is provided with a feed inlet.

The bottom of the washing tank is provided with a slag discharge port, the slag discharge port is provided with a gate valve in a matching way, and the lower side of the slag discharge port is provided with a back flush water gap.

The discharge port is of a vertical downward channel structure.

The utility model also discloses a wood chip rinsing machine, include novel wood chip rinsing machine's shell structure.

The utility model has the advantages that:

the utility model optimizes the shell of the wood chip washing machine, especially changes the baffle which is originally at a certain included angle with the discharging chute into a weir plate structure with an arc top in the design of the discharge port; the discharge gate weir plate design after the improvement can reduce the inside liquid level height of equipment, relies on the rotatory surface of water that arouses of rotor simultaneously undulant, just can make the wood chip under the drive of trickle, discharges via the discharge gate through the weir plate smoothly, has reduced the washing water consumption of wood chip rinsing machine.

Meanwhile, the water filling port does not need to work continuously, and the back washing water added at the slag discharging port can back wash a small amount of wood chips brought to the bottom to the upper layer of the washing water on one hand and can supplement the loss of the washing water on the other hand. And only when the liquid level sensor monitors that the liquid level is too low, the water filling port can be started to supplement.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 2, the housing structure of the novel wood chip washing machine of the embodiment includes a housing and a discharge port 8 disposed on one side of the housing, a washing tank is formed in the housing, and a rotor 6 with a shifting piece is disposed in cooperation with the washing tank. The washing tank is provided with a weir plate 10 at the joint of the discharge port 11, the top of the weir plate 10 is of an arc-shaped structure, and the top of the weir plate 10 is slightly higher than or maintains the water level in the washing tank.

In this embodiment, the discharge port 11 is a vertically downward channel structure.

A water filling port 2 is arranged above the water washing pool, a liquid level sensor 9 is arranged at the position of a liquid level 3 in the water washing pool, when the liquid level 3 is lower than a required liquid level, the liquid level sensor 9 sends a signal, and the water filling port 2 starts to fill water.

The arc-shaped weir plate 10 is slightly higher than or maintains the liquid level 3 in the washing tank, regular fluctuation is generated when the washing water is stirred by the rotor 6 during working, and the wood chips are driven to turn over the arc-shaped weir plate 10 and are discharged through the discharge hole 11. Because the loss of the washing water is not very fast according to the working principle, the water injection port 2 does not need to be injected continuously. When the liquid level 3 is lower than the required liquid level, the liquid level sensor 9 sends a signal, and the water filling port 2 starts to fill water.

The bottom of the washing pool is provided with a slag discharge port 4, the slag discharge port 4 is provided with a gate valve 5 in a matching way, the lower side of the slag discharge port is provided with a back flush water port 12, and the back flush water port 12 injects flushing water into heavy impurities deposited at the slag discharge port 4 to flush the wood chips contained in the heavy impurities to the upper layer of the washing water. This also makes it possible to replenish the washing water lost in a small amount.

The utility model optimizes the shell of the wood chip washing machine, especially changes the baffle which is originally at a certain included angle with the discharging chute into the weir plate 10 with the top of arc structure in the design of the discharge outlet; the discharge gate weir plate design after the improvement can reduce the inside liquid level height of equipment, relies on the surface of water fluctuation that 6 rotations of rotor arouse simultaneously, just can make the wood chip under the drive of trickle, discharges via the discharge gate through the weir plate smoothly, has reduced the washing water consumption of wood chip rinsing machine.
