Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a mixed material conveying device. Background Art

[0002] At present, limestone and volcanic ash powder used in cement production are both powdery materials with high moisture content, and are pre-mixed with phosphogypsum with high adhesion and then transported through a belt conveyor;

[0003] Because the mixing ratio of limestone with lower moisture content has been greatly reduced, the moisture content of the actual mixed material entering the conveyor exceeds 9%, causing the material to adhere to the conveyor belt, making it difficult to unload the material and affecting the safe and stable operation of the equipment.

[0004] Generally, a fixed scraper is used to clean the surface of the conveyor belt. During the operation, due to the effect of gravity, the residue in some materials may be deeply embedded in the conveyor belt. When these residues touch the fixed scraper, the scraper forcibly scrapes them off the surface of the conveyor belt under strong force, causing greater friction damage on the surface of the conveyor belt, which affects the working life of the conveyor belt.

[0005] For this reason, we propose a mixed material conveying device to solve the existing problems. Utility Model Content

[0006] The purpose of the utility model is to propose a mixed material conveying device in view of the problems existing in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mixed material conveying device, comprising a base plate, a conveyor belt, a mounting plate, a scraper and a slide bar, wherein the conveyor belt transmission is arranged between two base plates, a sliding sleeve is fixed to the inner wall of the lower end of the two base plates by bolts, a scraper is elastically inserted on the sliding sleeve, and the working surface of the scraper contacts the outer surface of the conveyor belt;

[0008] A slide bar is slidably installed inside the slide sleeve, a scraper is installed on the slide bar through bolts, a spring is symmetrically installed on the lower surface of the slide bar through bolts, a mounting plate is installed at the bottom opening of the slide sleeve through bolts, and the other end of the spring is fixed on the mounting plate;

[0009] Two bases are symmetrically installed on the mounting plate by bolts, and contacts are installed on the two bases. A touch plate is installed at the middle position of the lower surface of the slide bar by bolts, and an alarm is installed on the outer surface of the mounting plate, and the alarm is electrically connected to the two contacts.

[0010] Preferably, there are two substrates, and two rollers are symmetrically mounted between the two substrates.

[0011] A conveyor belt is arranged between the two roller shafts.

[0012] Preferably, the original length of the spring is greater than the inner depth of the sliding sleeve.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] During the use of the mixed material conveying device of the utility model, the conveyor belt works, and the wet mixed material moves under the transmission of the conveyor belt;

[0015] During the conveying process of the conveyor belt, the conveyor belt and the scraper rub against each other, and the scraper scrapes off the materials adhering to the surface of the conveyor belt, completing the self-cleaning operation of the conveyor belt surface;

[0016] At the same time, when the scraper touches the residue that is difficult to scrape out automatically, the scraper is retracted into the sliding sleeve under the action of force. At this time, the sliding bar presses the spring, causing the spring to deform, and the sliding bar drives the touch plate to press down onto the contact head. The circuit in the installation plate is connected and energized, so that the alarm works.

[0017] Personnel can observe the working frequency of the alarm. When the alarm works frequently, it means that the conveyor belt needs to be manually disassembled for maintenance, cleaning and replacement.

[0018] The utility model can avoid the situation where the conveyor belt is subjected to strong force during the process of automatically cleaning the conveyor belt surface, reduce the friction damage on the conveyor belt surface, and prolong the service life of the conveyor belt.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The conveyor belt 2 is arranged between two base plates 1. The inner walls of the lower ends of the two base plates 1 are fixed with a sliding sleeve 3 by bolts. The scraper 6 is elastically inserted into the sliding sleeve 3. The working surface of the scraper 6 contacts the outer surface of the conveyor belt 2.

[0028] Based on Example 1:

[0029] During the use of the mixed material conveying device of the utility model, the conveyor belt 2 is in operation, and the wet mixed material moves under the transmission of the conveyor belt 2;

[0030] During the conveying process of the conveyor belt 2, the conveyor belt 2 and the scraper 6 are in friction contact with each other, and the scraper 6 scrapes off the materials adhering to the surface of the conveyor belt 2, completing the self-cleaning operation of the surface of the conveyor belt 2;

[0031] At the same time, when the scraper 6 touches the residue that is difficult to scrape out automatically, the scraper 6 is retracted into the sliding sleeve 3 under the action of the force, and the slide bar 12 presses the spring 8, causing the spring 8 to deform, and the slide bar 12 drives the contact plate 10 to press down onto the contact 11, and the circuit in the mounting plate 5 is connected and energized, so that the alarm 7 works;

[0032] The personnel can observe the working frequency of the alarm 7. When the alarm 7 works frequently, it means that the conveyor belt 2 here needs to be manually disassembled by personnel for maintenance, cleaning and replacement.

[0040] The original length of the spring 8 is greater than the internal depth of the sliding sleeve 3;

[0041] By limiting the length of the spring 8 , it is ensured that the spring 8 has sufficient elastic force to push the scraper 6 against the surface of the conveyor belt 2 .
