Description

Technical Field

[0001] This utility model relates to the field of cooling water filtration technology for roll grinding machines, specifically to a grinding mud sedimentation tank. Background Technology

[0002] Steel rolling requires periodic roll replacement. Rolls that have been removed from the production line are ground to remove fatigue layers and reach the required precision before being put back into the rolling line. The rolls are ground on a special grinding machine. During grinding, a large amount of grinding heat and grinding mud are generated, which need to be carried away by cooling water. The main components of the grinding mud include the material removed from the rolls (iron) and the material shed from the grinding wheel (non-iron). The cooling water is recycled through a filtration system.

[0003] Currently, the cooling water filtration system for roll grinding machines is generally divided into two stages. The first stage uses a magnetic separator to filter the rolls and remove substances (iron); the second stage uses a paper filter to filter the substances (non-iron) that fall off the grinding wheel.

[0004] The existing technology has the following drawbacks:

[0005] 1. Cooling water carrying a large amount of grinding mud directly enters the magnetic separator, which is overloaded and frequently malfunctions.

[0006] 2. Ferrous and non-ferrous materials are mixed in the grinding mud, and the magnetic separator is not effective in separating them.

[0007] 3. Non-ferrous materials contain binders with strong adhesion, which can accumulate over time and clog the drain outlet of the magnetic separator.

[0008] 4. The cable chain of the paper filter press often punctures the filter paper, causing paper jams.

[0009] 5. Paper filter presses consume a lot of filter paper, and environmental treatment is difficult. Utility Model Content

[0010] The technical problem to be solved by this invention is that the cooling water filtration effect in the existing cooling water filtration system of the roll grinding machine is not ideal.

[0011] To solve the above problems, the technical solution adopted by this utility model is a grinding mud sedimentation tank, including a tank body, a mud baffle plate fixed obliquely on the inner side of the tank body, a water baffle plate fixed on the inner side of the tank body next to the mud baffle plate, a water tank fixed on the top of the tank body, and a water inlet on the top of the tank body. A drain outlet connected to the water tank is fixed on the top of the tank body, and a drain valve is connected to one side of the tank body. One end of the drain valve is connected to a drain pipe.

[0012] As a further embodiment of this invention, the height of the mudguard is less than the height of the box body.

[0013] As a further embodiment of this utility model: a lifting lug 1 and a lifting lug 2 are respectively fixed at the top center and one bottom side of the box body. The lifting lug 1 is a hoisting lug, and the lifting lug 2 is a slag-pouring lug.

[0014] As a further embodiment of this utility model: the inside of the box is filled with cooling water, and grinding mud settles at the bottom of the box.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. Cooling water enters the sedimentation tank directly, settling most of the grinding mud and significantly reducing the load on the magnetic separator.

[0017] 2. The cooling water after sedimentation improves the separation effect of the magnetic separator.

[0018] 3. Prevent the long-term accumulation of binders in non-ferrous materials from clogging the drain outlet of the magnetic separator.

[0019] 4. Eliminate the paper filter machine to avoid paper jams and save costs.

[0020] 5. Solve the problem of environmentally friendly filter paper disposal. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0029] Combined with appendix Figure 1-3 It can be seen that the tank includes a tank body 1, which is a steel structure water tank with a storage capacity of 1.5 cubic meters. A mudguard 2 is fixed obliquely on the inner side of the tank body 1 to block sediment. A water baffle 3 is fixed on the inner side of the tank body 1 next to the mudguard 2 to reduce the oscillation of cooling water and facilitate sufficient sedimentation. A water tank 4 is fixed on the top of the tank body 1 to guide the settled cooling water to the drain outlet 6. The top of the tank body 1 is provided with a water inlet 5, which is connected to the transition water tank of the roll grinding machine. The top of the tank body 1 is fixed with a drain outlet 6 connected to the water tank 4 to discharge the cooling water into the magnetic separator. A drain valve 7 is connected to one side of the tank body 1 to drain the upper layer of cooling water before slag is dumped to prevent the cooling water 11 in the tank body 1 from overflowing during hoisting. One end of the drain valve 7 is connected to a drain pipe 8 to connect the cooling water to an external water tank.

[0030] The height of the mudguard 2 is less than the height of the box body 1; the top middle and one side bottom of the box body 1 are respectively fixed with lifting lug 1 9 and lifting lug 2 10. Lifting lug 1 9 is a hoisting lug, and lifting lug 2 10 is a slag dumping lug; the box body 1 is filled with cooling water 11, and grinding mud 12 settles at the bottom of the box body 1. When the grinding mud 12 reaches about 3 / 4 of the height of the box body 1, slag dumping must be performed.

[0031] The working principle of this application is as follows: before the cooling water 11 undergoes magnetic separation, it first passes through the process shown in the attached document. Figure 1 , 2 The items numbered ① to ⑧ in the middle are settled in the box 1. Specifically, the cooling water 11 is discharged from the roller grinding machine and enters the box 1 from the water inlet 5. The grinding mud 12 will settle in the box 1 under the obstruction of the mud baffle 2. The cooling water 11 will be discharged into the magnetic separator from the drain outlet 6 through the water tank 4, thereby achieving the initial sedimentation and filtration of the cooling water 11.

[0032] When slag removal is required, excess cooling water 11 is first discharged through drain valve 7, then the box 1 is lifted by crane through lifting lug 1 9, and then slag is removed by lifting through lifting lug 2 10.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
