Technical Field
[0001] This utility model relates to the field of water tank technology, and in particular to a quantitatively adjustable hot water tank for concrete mixing plants. Background Technology
[0002] A concrete mixing plant mainly consists of five major systems: a mixing host, a material weighing system, a material conveying system, a material storage system, and a control system, as well as other auxiliary facilities. In addition, the mixing plant is equipped with a hot water tank during operation, which is used to provide hot water to the mixing plant to complete the mixing of concrete.
[0003] The existing hot water tanks in concrete mixing plants have some problems in practical applications. The amount of hot water required by the mixing plant when mixing concrete is fixed. In the existing technology, the hot water is generally delivered quantitatively through flow control structures such as flow valves. However, the cost of control through flow valves and other structures is relatively high. In addition, the water tank structure in the existing technology is simple. It uses a temperature control system and electric heating tubes. In order to maintain the water temperature inside the tank, the electric heating tubes need to operate at high power after water is added or removed to ensure a continuous supply of hot water, which results in a certain degree of energy waste.
[0004] Therefore, it is necessary to invent a quantitatively adjustable hot water tank for concrete mixing plants to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a quantitatively adjustable hot water tank for concrete mixing plants to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a quantitatively adjustable hot water tank for a concrete mixing plant, comprising a tank body, two partitions fixedly arranged at the top of the tank body, the two partitions being symmetrically arranged, a partition cover fixedly arranged inside the tank body, the partition cover being a "U" shaped structure, both partitions being located inside the partition cover, a gap being provided between the top of the partition cover and the top inner wall of the tank body, multiple main heating rods fixedly arranged at the bottom of the tank body, two sets of symmetrically distributed first heating rods and second heating rods fixedly arranged inside the tank body, each set of first heating rods and second heating rods having multiple rods, the two sets of first heating rods and two sets of second heating rods being staggered, and both sets of first heating rods and two sets of second heating rods being located outside the partition cover, heat-conducting fins fixedly arranged in the middle of the multiple second heating rods, one end of the heat-conducting fins being located between the partition cover and the partitions;
[0007] A water outlet cover is fixedly installed at the bottom of the main body of the water tank, and a three-way valve is fixedly installed at the bottom of the water outlet cover.
[0008] Preferably, a return water pipe is fixedly provided at one end of the three-way valve, and a circulation pump is provided below the main body of the water tank, with the input end of the circulation pump connected to one end of the return water pipe.
[0009] Preferably, a water inlet is provided through the top of the outer side wall of the water tank body, and one end of the water inlet is located between two partitions.
[0010] Preferably, a water supply pipe is fixedly provided at one end of the water supply inlet located on the outside of the water tank body, and a connecting pipe is fixedly provided in the middle of the water supply pipe, with the bottom end of the connecting pipe connected to the output end of the circulation pump.
[0011] Preferably, a water supply valve is fixedly provided at one end of the water supply pipe, and a connecting flange is fixedly provided at one end of the water supply valve.
[0012] Preferably, a heightening bracket is fixedly provided on the outside of the water tank body.
[0013] Preferably, the end of the heat-conducting fin located inside the partition cover is configured with an upward inclined structure.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] 1. This utility model provides a partition and a dividing cover inside the main body of the water tank. The dividing cover divides the interior of the main body of the water tank into two parts, and the water storage capacity between the dividing cover and the inner wall of the main body of the water tank is fixed. When the mixing plant is mixing concrete, the water between the dividing cover and the inner wall of the main body of the water tank can be directly drained to achieve the effect of quantitative water release. By setting a main heating rod, a first heating rod and a second heating rod between the dividing cover and the main body of the water tank, and setting multiple sets of heating rods in the cavity between the dividing cover and the main body of the water tank, the heating load of the heating rods is reduced while ensuring the water temperature of the concrete mixing water, thereby achieving the effect of reducing energy consumption.
[0016] 2. This utility model, by setting up a partition, a partition cover, a return water pipe, and a water supply pipe, allows water inside and outside the partition cover to slowly exchange heat when the device is not drained, thereby controlling the water temperature inside the main body of the water tank. Furthermore, the circulation pump can circulate hot water from outside the partition cover to inside the partition cover through the return water pipe and the water supply pipe, controlling the temperature inside the main body of the water tank by mixing hot and cold water. At the same time, the partition can act as a guide, allowing hot and cold water to flow along a fixed trajectory inside the main body of the water tank, so that cold water can move to the outside of the partition cover for heating when the mixing plant does not need to drain water, thus ensuring a constant water temperature inside the main body of the water tank.

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.
[0023] This utility model provides, for example Figure 1-4 The present invention relates to a quantitatively adjustable hot water tank for a concrete mixing plant, comprising a tank body 1, two partitions 2 fixedly installed at the top of the tank body 1, the two partitions 2 being symmetrically arranged, a partition cover 3 fixedly installed inside the tank body 1, the partition cover 3 being a "U" shaped structure, the two partitions 2 being located inside the partition cover 3, a gap being provided between the top of the partition cover 3 and the top inner wall of the tank body 1, the partition cover 3 dividing the interior of the tank body 1 into two chambers, and the two chambers being connected through the gap between the top of the partition cover 3 and the top inner wall of the tank body 1;

Both sets of first heating rods 6 and two sets of second heating rods 7 are located on the outside of the partition cover 3. It should be noted that the first heating rods 6 and second heating rods 7 are used for slow heating, so the number of first heating rods 6 and second heating rods 7 is relatively small. As long as the water heating in the outer cavity of the partition cover 3 can be completed within the water cycle of the mixing plant, the number of them is not limited. The main heating rods 5 are used for rapid heating. Their number is staggered and the distribution density is relatively large. As long as the cold water is heated to the temperature required by the mixing plant while the water is discharged, the number of them is not limited.
[0025] A heat-conducting fin 8 is fixedly provided in the middle of a plurality of second heating rods 7, and one end of the heat-conducting fin 8 is located between the partition cover 3 and the partition plate 2. The end of the heat-conducting fin 8 located inside the partition cover 3 is set as an upward inclined structure. The design of the inclined structure increases the contact area between the heat-conducting fin 8 and the water, thereby improving the heat exchange efficiency between it and the water.
[0026] A water outlet cover 4 is fixedly installed at the bottom of the water tank body 1. A three-way valve 9 is fixedly installed at the bottom of the water outlet cover 4. One end of the three-way valve 9 is used to connect to the water discharge pipe to realize the water supply of the mixing station.

[0027] One end of the three-way valve 9 is fixedly equipped with a return water pipe 10. A circulation pump 11 is provided below the main body of the water tank 1. The input end of the circulation pump 11 is connected to one end of the return water pipe 10. A water inlet 13 is provided through the top of the outer wall of the main body of the water tank 1.

[0028] A water supply valve 15 is fixedly provided at one end of the water supply pipe 14, and a connecting flange 16 is fixedly provided at one end of the water supply valve 15. The connecting flange 16 is used to connect to the water supply pipeline to control the water supply of the device.
[0029] An extension frame 17 is fixedly installed on the outside of the water tank body 1. The extension frame 17 is used to raise the water tank body 1 so that water can be discharged from the bottom of the water tank body 1.
[0030] Working principle of this utility model:
[0031] When this device is in use, the partition cover 3 divides the interior of the water tank body 1 into two chambers. The water in the outer chamber of the partition cover 3 is heated by the main heating rod 5, the first heating rod 6 and the second heating rod 7. When mixing concrete at the mixing plant, the three-way valve 9 is opened, and the heated water on the outer side of the partition cover 3 is discharged through the water outlet cover 4 and the three-way valve 9 to ensure the water supply for the mixing plant. During the water discharge process, the water storage capacity of the outer chamber of the partition cover 3 is equal to the water required for a single batch of concrete mixing at the mixing plant. The three-way valve 9 can be opened until the hot water in the outer chamber of the partition cover 3 is emptied, thus achieving quantitative water discharge.
[0032] After the water is drained, the water in the outer chamber of the partition cover 3 is emptied. At this time, the device needs to be replenished with water. Water in the water supply pipeline is transported to the water tank body 1 through the water replenishment pipe 14 to complete the water replenishment. After the replenished water enters the water tank body 1 through the water replenishment port 13, the replenished water directly enters the chamber between the two partitions 2. At this time, the water volume in the inner chamber of the partition cover 3 increases and the water level rises. After the water level rises, the water in the inner chamber of the partition cover 3 overflows into the outer chamber of the partition cover 3 through the gap between the top of the partition cover 3 and the water tank body 1 to replenish the water in the outer chamber of the partition cover 3. Continue to add water until the outer chamber of the partition cover 3 is filled with water to complete the water replenishment of the device.
[0033] After water replenishment, the first heating rod 6 and the second heating rod 7 are energized to heat the water in the outer chamber of the partition cover 3. At the same time, the second heating rod 7 heats the water between the inner wall of the partition cover 3 and the partition plate 2 through the heat-conducting fins 8. During this process, the water in the outer chamber of the partition cover 3 is heated quickly to facilitate the next water use, while the water in the inner chamber of the partition cover 3 is heated slowly. During this process, the main heating rod 5 does not work, and the device operates in a low-power state, achieving slow heating of the water in the main body of the water tank 1. Furthermore, considering that the water inside the partition cover 3 heats up slowly, the circulating pump 11 can extract hot water from the outside of the partition cover 3 and transport it to the inner chamber of the partition cover 3 to achieve hot water circulation. This enables rapid heating of the water in the two chambers inside the main body of the water tank 1. When the water temperature in the two chambers inside the main body of the water tank 1 reaches the requirements of the mixing station, the first heating rod 6 and the second heating rod 7 can stop working to reduce the energy consumption of the device.
[0034] During the water discharge process, if the water temperature in the outer chamber of the partition cover 3 meets the requirements of the mixing plant, water can be discharged directly. If the water temperature in the outer chamber of the partition cover 3 is lower than the requirements of the mixing plant, the main heating rod 5 will be activated during the water discharge process. The dense main heating rod 5 can quickly heat the water in the outer chamber of the partition cover 3 to meet the water demand of the mixing plant.
[0035] It should be noted that the water tank body 1, three-way valve 9, circulation pump 11, water supply valve 15 and other structures in this embodiment all adopt the corresponding structures in the prior art. The main heating rod 5, the first heating rod 6 and the second heating rod 7 are all electric heating rods, and are equipped with corresponding controllers and power supplies. In addition, the water tank body 1 is provided with a heat insulation layer on the outside.
[0036] It should be further explained that, in order to meet the monitoring of water temperature and water level in the two chambers inside the water tank body 1 in this embodiment, multiple sets of temperature sensors and water level sensors are installed inside the water tank body 1 to meet the requirements for monitoring water temperature and water level. The installation positions of the temperature sensors and water level sensors can be selected according to the actual situation, such as on the side wall or top of the partition cover 3. Their positions are not limited as long as the normal implementation of this embodiment is met. The above technical means are common in the field and are not limited here.
