Description

Technical Field

[0001] This utility model relates to the field of sand mixer technology, and in particular to a sand mixer that is easy to clean. Background Technology

[0002] A sand mixer is a mechanical device used to mix materials such as sand and binders. In the field of refractory materials, sand mixers also play a crucial role. They are primarily used to thoroughly and uniformly mix various raw materials for refractory materials, such as refractory aggregates of different particle sizes, fine powders, and binders. Through the action of the sand mixer, these materials achieve a good mixing state, ensuring the uniformity and stability of the performance of refractory products. Sand mixers can precisely control the degree and uniformity of mixing, adapting to the requirements of different refractory material formulations and production processes. Their working principle typically utilizes mechanical stirring and tumbling to promote full contact and fusion between materials.

[0003] The prior art discloses a sand mixer for producing refractory materials, application number 202022793969.2, which includes a sand mixing drum with legs at the bottom. A first rotating shaft is rotatably mounted at the center of the sand mixing drum, with its bottom extending beyond the bottom of the drum. The bottom of the first rotating shaft is driven by a rotary drive mechanism, and two sand mixing mechanisms are evenly arranged on the first rotating shaft. Each sand mixing mechanism includes a grinding wheel mounted on the first rotating shaft, a shovel with a right-angled triangular cross-section mounted on the first rotating shaft and below the grinding wheel, and an anvil plate that mates with the grinding wheel on the rear side of the outer end of the shovel plate. The outer ends of the shovel plate and the anvil plate are arc-shaped, mate with the inner wall of the sand mixing drum, and a scraper is vertically mounted on the upper part of the anvil plate, with its outer end contacting the inner wall of the sand mixing drum. This invention can not only achieve thorough mixing of refractory materials but also prevent them from sticking to the side walls and bottom of the sand mixing drum. However, the prior art still has problems such as unsatisfactory crushing effect, inconvenient cleaning, and insufficient mixing. Therefore, we propose a sand mixer that is easy to clean to solve the above problems. Utility Model Content

[0004] To address the shortcomings mentioned above, this utility model provides a sand mixer that is easy to clean, enabling it to crush materials more effectively, clean them more conveniently and quickly, and mix them more thoroughly.

[0005] To solve the above problems, the technical solution provided by this utility model is as follows:

[0007] Furthermore, the cleaning mechanism includes a cleaning motor, a mounting plate, and a scraper. The output end of the cleaning motor is fixedly connected to the mounting plate, the mounting plate is rotatably connected to the inner wall of the sand mixing box, and a scraper is fixedly installed on the left side of the mounting plate, the scraper being in contact with the inner wall of the sand mixing box.

[0008] Furthermore, the crushing mechanism includes a stirring motor, a stirring rod, a connecting seat, and stirring blades. The output end of the stirring motor is fixedly connected to the left end of the stirring rod, the right end of the stirring rod is rotatably connected to the connecting seat, the stirring blades are fixedly mounted on the stirring rod, and the connecting seat is slidably connected to the mounting plate.

[0009] Furthermore, the crushing mechanism is symmetrically arranged on the left and right sides of the feed hopper. The crushing mechanism includes a cylinder, a crushing plate and sharp teeth. The output end of the cylinder is fixedly connected to the crushing plate, and sharp teeth are fixedly arranged on the crushing plate. The two sharp teeth on the left and right sides can mesh with each other.

[0011] Furthermore, a discharge valve is installed at the discharge pipe.

[0012] Furthermore, a support leg is fixedly installed at the lower end of the sand mixing box.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The crushing effect is more significant. Through the symmetrical crushing mechanism and the interlocking of sharp teeth, the material can be crushed into finer and more uniform pieces.

[0015] 2. Cleaning is more convenient and efficient. The specially designed cleaning mechanism can quickly and thoroughly remove residual materials from the inner wall of the sand mixing box.

[0016] 3. More thorough mixing: The design of the mixing structure allows the materials to be more thoroughly mixed in the mixing box, improving the mixing quality.

[0017] In summary, this easy-to-clean sand mixer has wide applicability, addressing the problems of insufficient crushing effect, inconvenient cleaning, and inadequate mixing in the existing technologies mentioned in the background section. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and examples, but the examples given are not intended to limit the present utility model.

[0022] like Figure 1 As shown, the embodiment of this utility model includes a sand mixing box 1 and a crushing box 2. The crushing box 2 is fixedly installed on the sand mixing box 1 by a support frame 8. The crushing box 2 is connected to the sand mixing box 1 through a connecting pipe 4. A feed hopper 3 is provided at the upper end of the crushing box 2. A discharge pipe 5 is provided at the lower end of the sand mixing box 1. A discharge valve 22 is installed at the discharge pipe 5. A support leg 7 is fixedly installed at the lower end of the sand mixing box 1. A crushing mechanism is provided inside the crushing box 2. A stirring structure and a cleaning mechanism are provided inside the sand mixing box 1. A liquid inlet 9 is provided at the upper end of the sand mixing box 1. The liquid inlet 9 is connected to a liquid storage tank 6 through a connecting pipe 10. A pump body 11 is installed at the connecting pipe 10.

[0023] The cleaning mechanism includes a cleaning motor 19, a mounting plate 20, and a scraper 21. The output end of the cleaning motor 19 is fixedly connected to the mounting plate 20. The mounting plate 20 is rotatably connected to the inner wall of the sand mixing box 1. The scraper 21 is fixedly installed on the left side of the mounting plate 20 and is in contact with the inner wall of the sand mixing box 1.

[0024] The crushing mechanism includes a stirring motor 15, a stirring rod 16, a connecting seat 17, and a stirring blade 18. The output end of the stirring motor 15 is fixedly connected to the left end of the stirring rod 16, the right end of the stirring rod 16 is rotatably connected to the connecting seat 17, the stirring blade 18 is fixedly installed on the stirring rod 16, and the connecting seat 17 is slidably connected to the mounting plate 20.

[0025] The crushing mechanism is symmetrically arranged on the left and right sides of the feed hopper 3. The crushing mechanism includes a cylinder 12, a crushing plate 13 and sharp teeth 14. The output end of the cylinder 12 is fixedly connected to the crushing plate 13. Sharp teeth 14 are fixedly arranged on the crushing plate 13, and the two sharp teeth 14 on the left and right sides can mesh with each other.

[0026] The material to be mixed is poured from the feed hopper 3 into the crushing chamber 2.

[0027] Inside the crushing chamber 2, the cylinders 12 on both sides push the crushing plates 13 to move towards each other, so that the sharp teeth 14 on the crushing plates 13 bite each other to perform preliminary crushing of the material.

[0028] After initial crushing, the material enters the mixing box 1 through the connecting pipe 4.

[0029] In the sand mixing tank 1, the stirring motor 15 drives the stirring rod 16 to rotate, and the stirring blades 18 stir and mix the materials. At the same time, liquid can be added to the sand mixing tank 1 from the liquid storage tank 6 through the liquid inlet 9, the connecting pipe 10 and the pump body 11 to meet the mixing requirements.

[0030] When the sand mixing work is completed and cleaning is required, the cleaning motor 19 is started. The cleaning motor 19 drives the mounting plate 20 to rotate, and the scraper 21 on the left side of the mounting plate 20 rotates accordingly. Since the scraper 21 is in contact with the inner wall of the sand mixing box 1, the residual material attached to the inner wall of the sand mixing box 1 is scraped off, thereby realizing the cleaning function.
