Description

Technical Field

[0001] This utility model belongs to the technical field of boiling tanks, specifically relating to a cement boiling tank. Background Technology

[0002] In the field of cement stability testing, boiling tanks are key testing equipment, and their traditional structure typically uses a fixed metal support frame to support cement specimens. However, the existing devices have significant drawbacks in practical applications: when the specimens undergo a chemical reaction in a high-temperature, high-pressure environment, the precipitated alkaline substances such as calcium hydroxide combine with water vapor inside the tank to form hard scale, which easily adheres to the bottom and side walls of the tank. Because the support frame and the tank body are rigidly connected, operators cannot simultaneously remove the deposited scale when removing the specimens, requiring additional manual scraping or chemical cleaning. This not only significantly increases the intensity of maintenance work, but the residual scale layer can also reduce heat transfer efficiency during subsequent tests and even affect the accuracy of the test data. Therefore, there is an urgent need for an innovative boiling tank structural design that can achieve simultaneous scale removal. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a template to solve the problems in the prior art where operators cannot simultaneously remove deposited dirt when taking out test blocks, resulting in high subsequent maintenance intensity and affecting the heat transfer efficiency of the boiling tank.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A cement boiling tank includes a main body, characterized in that: four fitting grooves are formed on the upper surface of the main body; a dirt filter frame is placed inside the main body, the height of the dirt filter frame is higher than the drain outlet of the main body, and two horizontal plates are fixedly fixedly arranged symmetrically inside the dirt filter frame; a scraper frame is fixedly arranged on the upper surface of the dirt filter frame, the top of the scraper frame is inclined outward and fits against the inner surface of the main body; two vertical rods are symmetrically arranged on the upper surface of the horizontal plates in the front-back direction, and the vertical rods are detachably connected to the horizontal plates; multiple hollow frames are installed between the four vertical rods, and the position of the hollow frames can be adjusted vertically; a U-shaped rod is fixedly arranged between each pair of corresponding vertical rods; two sealing blocks are fixedly arranged on the outer surface of the U-shaped rod, the sealing blocks are engaged with the corresponding fitting grooves, and the U-shaped rods pass through the corresponding fitting grooves and extend to the outside of the main body.

[0006] In the above technical solution, the horizontal plate is symmetrically perforated with soil-shaped rotating columns that can rotate around their own axis, and each soil-shaped rotating column has an internally threaded hole on its top surface. The lower end of the plumb rod is provided with an externally threaded structure that matches the internally threaded hole, and the plumb rod is detachably fixed in the threaded hole of the soil-shaped rotating column through a threaded pair.

[0007] In the above technical solution, sliding sleeves are fixedly installed at the four corners of the hollow frame, and the sliding sleeves are slidably engaged with the corresponding plumb rods. Each pair of diagonally positioned sliding sleeves has a through-hole with an internal thread, and a locking bolt is screwed into the through-hole. When the locking bolt is screwed axially inward until its inner end is tightly fitted against the outer surface of the corresponding plumb rod, the sliding sleeve and the plumb rod are relatively fixed.

[0008] In the above technical solution, four inverted T-shaped columns are fixedly arranged symmetrically on the lower surface of the hollow frame.

[0009] In the above technical solution, four support legs are symmetrically distributed and fixed on the lower surface of the dirt filter frame, and the bottom end face of the support legs forms a surface contact fit with the bottom surface of the inner cavity of the boiling tank body.

[0011] The advantages of this cement boiling tank compared to existing technologies are as follows:

[0012] This invention, by setting up a dirt filter frame, a scraper frame, a vertical bar, a U-shaped bar, and a hollow frame, enables the scraper frame to clean along the inner wall of the chamber during the hoisting and removal of cement test blocks. This allows for the simultaneous removal of test blocks and self-cleaning of the chamber, effectively solving the technical problems of low maintenance efficiency and increased thermal resistance in traditional processes. In addition, by making the horizontal plate on the dirt filter frame and the vertical bar detachable, the vertical bar can be removed to facilitate subsequent cleaning of the dirt filter frame and the scraper frame.

Detailed Implementation

[0021] 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.

[0022] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-7 This utility model provides a technical solution:

[0023] A cement boiling tank includes a main body 1, characterized in that: four fitting grooves 11 are formed on the upper surface of the main body 1, and a dirt filter frame 2 is placed inside the main body 1. The dirt filter frame 2 consists of an outer frame and a high-temperature resistant and corrosion-resistant metal filter screen fixedly connected to it. The filter screen has a filter diameter of 10-30 micrometers and is mainly used to intercept calcium hydroxide particles generated after the cement test block reacts in the main body 1. The dirt filter frame 2 is located at a height higher than the drain outlet of the main body 1 to ensure the filtration effect.

[0024] Combination Figure 3 and Figure 4 As shown, two horizontal plates 21 are fixedly fixedly arranged symmetrically inside the dirt filter frame 2. A scraper frame 22 is fixedly arranged on the upper surface of the dirt filter frame 2. The top of the scraper frame 22 is inclined outward and fits against the inner surface of the boiling tank body 1. When the scraper frame 22 moves upward together with the dirt filter frame 2, the dirt on the inner wall of the boiling tank body 1 can be scraped off by the scraper frame 22 and collected in the dirt filter frame 2. The dirt filter frame 2 can also collect the settled dirt.

[0025] Combination Figure 4 and Figure 5 As shown, two vertical rods 4 are symmetrically arranged on the upper surface of the horizontal plate 21 along the front-back direction, and the vertical rods 4 are detachably connected to the horizontal plate 21. Multiple hollow frames 5 are installed between the four vertical rods 4. The hollow frames 5 are used to hold the cement test blocks to be tested. The position of the hollow frame 5 can be adjusted vertically. When the upper hollow frame 5 is attached and fixed to the cement test block below, it can cooperate with the lower hollow frame 5 to clamp and fix the cement test block, which can ensure the stability of the cement test block when boiling water is churning.

[0026] Combination Figure 4 , Figure 1 and Figure 2 As shown, a U-shaped rod 41 is fixedly installed between the two corresponding vertical rods 4 at the front and rear. Both the vertical rods 4 and the U-shaped rod 41 are made of Hastelloy alloy, which has low thermal conductivity and high corrosion resistance. Two sealing sleeves 42 are fixedly installed on the outer surface of the U-shaped rod 41. The sealing sleeves 42 are engaged with the corresponding fitting grooves 11. The U-shaped rod 41 passes through the corresponding fitting grooves 11 and extends to the outside of the boiling tank body 1. When the lid of the boiling tank body 1 is closed, the lower surface of the lid is in contact with the upper surface of the sealing sleeves 42, which can ensure the sealing of the boiling tank body 1 and prevent hot steam from leaking from the fitting grooves 11.

[0027] like Figure 5 As shown, a soil-shaped rotating column 3 that can rotate around its own axis is symmetrically arranged through the horizontal plate 21 in the front-back direction. The top surface of the soil-shaped rotating column 3 is provided with internal threaded holes in the axial direction. The lower end of the vertical rod 4 is provided with an external thread structure that matches the internal threaded hole. The vertical rod 4 is detachably fixed in the threaded hole of the soil-shaped rotating column 3 through the threaded pair. By rotating the soil-shaped rotating column 3, the lower end of the vertical rod 4 can be disengaged from the internal threaded hole, and the vertical rod 4 can be disengaged from the horizontal plate 21 to complete the disassembly. After disassembly, it is convenient to use external cleaning tools, such as cleaning brushes, to clean the dirt filter frame 2 and scraper frame 22.

[0028] Combination Figure 6 and Figure 4 As shown, sliding sleeves 51 are fixedly installed at the four corners of the hollow frame 5, and the sliding sleeves 51 are slidably sleeved with the corresponding vertical rods 4; each pair of sliding sleeves 51 set diagonally is provided with an internal threaded through hole, and a locking bolt 6 is screwed into the internal threaded through hole; when the locking bolt 6 is screwed inward along the axial direction until its inner end is tightly fitted with the outer surface of the corresponding vertical rod 4, the sliding sleeve 51 and the vertical rod 4 are relatively fixed. By loosening the locking bolt 6, the position of the hollow frame 5 can be moved up and down to meet the placement requirements of cement test blocks of different heights.

[0029] To reduce the contact area between the cement test block and the upper perforated frame 5, and to increase its contact area with boiling water, such as... Figure 6 As shown, four inverted T-shaped columns 52 are fixedly installed on the lower surface of the hollow frame 5 in a symmetrical manner. The four inverted T-shaped columns 52 can contact the upper surface of the cement test block from four points and provide a larger flow space for boiling water.

[0030] By setting the inverted T-shaped column 52, a four-point symmetrical contact mode can be adopted, which improves the original planar contact to discrete point contact. The contact area is reduced by more than 70%, thereby locking the contact area during clamping. The reduction in contact area increases the effective contact area of ​​the cement block with boiling water by about 40%, significantly improving the heat exchange efficiency.

[0031] During the reaction of the cement test block, in order to reduce the stress on the U-shaped rod 41 and prevent it from deforming and being removed from the fitting groove 11, four support legs 23 need to be symmetrically distributed and fixed on the lower surface of the dirt filter frame 2. The bottom end face of the support leg 23 forms a surface contact fit with the bottom surface of the inner cavity of the boiling tank body 1. The support legs 23 can be used to support the cement test block, effectively reducing the risk of deformation of the U-shaped rod 41.

[0032] Finally, when removing the reacted cement sample from the main body 1 of the boiling tank, to address the issue of the U-shaped rod 41 being too hot and requiring cooling before operation, thus reducing experimental efficiency, a ceramic sleeve 43 is fixedly fitted onto the outer surface of the U-shaped rod 41. The ceramic sleeve 43 is a high-purity alumina ceramic sleeve with a thickness of 1.5-2mm, and an anti-slip rubber sleeve 44 is fitted onto the outer surface of the ceramic sleeve 43. The ceramic sleeve 43 can reduce the surface temperature of the U-shaped rod 41 by 80%, thereby reducing the temperature of contact with the human hand during operation, shortening the cooling time of the U-shaped rod 41, and improving experimental efficiency.

[0033] Working Principle: In use, first adjust the distance between the two perforated frames 5, and place the cement test block to be tested on the perforated frame 5. Multiple cement test blocks can be placed simultaneously for boiling tests, facilitating experimental comparison. Then, tighten the corresponding locking bolts 6 to secure the cement test block using the upper and lower perforated frames 5. Next, two operators work together, using a U-shaped rod 4 to lift the dirt filter frame 2, scraper frame 22, the perforated frame 5 with the cement test block, and the plumb rod 4 into the boiling tank body 1. During this process, the sealing sleeve 42 must be inserted into the fitting groove 11. Afterward, water is added to the boiling tank body 1, ensuring the water level covers the cement test block. Then, the lid of the boiling tank body 1 is closed, and the heating reaction begins.

[0034] After the reaction is complete, the pressure is released using the pressure relief structure on the lid of the boiling tank body 1, and then the boiling water is discharged. During the wastewater discharge process, the dirt filter frame 2 intercepts the deposited dirt. Next, the lid of the boiling tank body 1 is opened, and again, two people operate the system, using a U-shaped rod 41 to lift and remove the dirt filter frame 2, scraper frame 22, the perforated frame 5 with the cement test block, and the plumb rod 4. During the lifting of the dirt filter frame 2 and scraper frame 22, the scraper frame 22 scrapes off the dirt adhering to the inner wall of the boiling tank body 1 and guides it into the dirt filter frame 2 for collection. In this way, while removing the cement test block, the residual dirt inside the boiling tank body 1 is effectively cleaned, solving the problems of existing technologies where operators cannot simultaneously remove deposited dirt when removing the test block, resulting in high subsequent maintenance intensity and affecting the heat transfer efficiency of the boiling tank.
